Toshiba romless MXM-II HD4650 DDR3 1 GB @ Acer 5920G soldering project for beginners

@.NetRolller 3D: Indeed, the given fix is more a workaround than a real solution, but I like such ways a lot. It shows the creativity and enthusiasm of the users, but I also like the professional solutions. E. g., one cannot/shouldn't sell a notebook with such workarounds. - I thought, your tutorials(s) for all the different bios at your thread " Acer MXM BIOS Mods and discussion" give the answer for many corrupted/strange MXM structures. I am not sure, if the MXM standard "has told" the companies to add the cards BIOS to a chip at the card (as now for my card) or if it is allowed to add the vBIOS to the system bios of a special laptop (as originally for the unmodded Toshiba card). The second option makes the card incompatible for the use at other notebooks, no "plug and play". At least you need to change the vBIOS "space" of the system BIOS every time you change a BIOSless video card or you need to implement an universal MXM bios - which should work for every possible card - OR you need to find such great NBR hard- and software tutorials.

@triturbo: The Radeon Bios Editor tells me, that the selectable voltages are hard-wired to the card and for the Toshiba vBIOS the highest value is 1.1 V. I am not sure why, but the overclocked card runs very stable and without problems at that voltage. Just take a look:

Weekend result: I run a little standard 3DMark06 benchmark updated to the last official patch (v1.2.0 v120_1901) for my Toshiba 1GB DDR3 HD4650 card with the added M25P10A and modded vBIOS and Windows 7 64bit. I used the Radeon Bios Editor v1.28 to change the clocks of the GPU (to 675 MHz) and memory (to 800 MHz) and set the Voltage to the maximum available value for the card (to 1.100V). I clicked on the "clock tuning wizard" of the tool to change all settings. Manually editing the frequencies ended up in problems while booting the (windows) system. I used the mobility modded (hardwareheaven.com) ATI Catalyst 9.12 drivers 64bit for Windows 7 (9-12_vista64_win7_64_dd_ccc_wdm_enu) after removing the old ATI drivers. The T9500 CPU was overclocked by Throttlestop to 2800 MHz. Here are the stats for the benchmark. I used the standard settings of the tool and additionally pasted three infos of the graphic card and cpu:



You can compare it to tirturbos results: http://forum.notebookreview.com/gam...424963-msis-hd4670-running-my-acer-5920g.html. My cpu score is a bit higher, because of the overclocking, I guess. The other scores are higher for triturbo.

If somebody wants to have more tests, just tell me. Regards.

 

It could be the case, so even with modified vBIOS it's possible that you wont see 1,2v. Yeah, it's stable, I'm running mine @1,1v so I can't see why it shouldn't be. The problem would be if you want to get more out of it, then 1,1v would be insufficient. Nice results

 

I'd say the only way to get a higher voltage is with a hardware mod.

 

Thanks for your tremendous support to my small project!

@.NetRolller 3D: Hardware mod could be the only possibility. - Maybe I need to add some resistors to change the max. voltage of the card. I have to search for such mods tomorrow. - I know, there are tutorials at the net (e.g. Example - GTX285 voltage mod (German)), but I need to find more specific information for my Toshiba MXM-II HD4650 card. May I kindly ask again, do you have any information as you seem to know every detail for this card?

@triturbo and all enthusiastic NBR users: I overclocked the card a bit tonight at 1.1 V to 720 MHz (=gpu) and 800 MHz (=memory). Be careful, watch the temperatures and stability! I played a bit with GPUTool CPT1 to find the max GPU frequency (WITHOUT modding the vBIOS via RBE) and then subtracted 5 MHz as safety value, fired up the 3Dmark06:



Can overvolting stabilize the card at higher frequencies? - The temperature is already a bit high at 1.1 V, ca. 85°C, but the card seems to be stable. -- Maybe, adding more voltage is not a good idea then. -- Some more new questions to find the answer...

 

Adding more voltage would definitely improve stability, it would also bring you more headroom for overclocking, but it's going to bring like +10ºC. King of Interns was researching the matter of hard modding the HD4670, but I don't think that he succeeded though. I could ask him if you want to, but both boards have their differences.

 

Hi triturbo, every information is welcome! Please ask your friend and tell him about my project or do you think, The Great King of Interns would answer me - just a small peasant - directly? For the cooling problem I saved another joker card: I still have the old heatsink of a Targa Visionary XP10 (died in 2012 by charred voltage regulator chips at the board) at my spare parts box which should fit fine after some cutting, rasping and polishing work. I already use the cooler next to the card, but additionally mounting the adjusted heatsink should improve the cooling system and, yes, I will not try to hit the GPU chip directly.

EDIT: Added a nice link describing the modding of graphic cards in general. A nice read for me:
http://www.techspot.com/tweaks/radeon_voltmod/

 

*** UPGRADED the CPU to an Intel X9100 @ Acer 5920G***

No news, connected to "the overvolting idea" for my MXM graphic card, BUT, I was able to get and mount one of the rare X9100 CPUs ( FSB downclock mod applied) for my Acer:



The temperatures are ok at normal use and also for gaming at the 3.2 GHz level.

Though, A continuous stresstest with the tool PRIME95 (a fine calculator for prime numbers) gives NO ERRORS, BUT TEMPERATURES UP TO 90°C for both cores. I will post some pictures of an optimized cooling system soon and hope to get better temps then.

DONE: See the next post...

 

*** UPGRADED the CPU to an Intel X9100 @ Acer 5920G - Simple Cooling Mod *** :hi2: Here is the NB with the second cooler ( see #56) mounted. I could use a native screw of the casing next to the HDD, a screw at the GPU cooler and clamped the plate at a third point to mount the construction tightly to the metal elements of the nb to achieve a maximum surface. Therefore, I customized a small metal heatsink (for an old 486 CPU, cut into parts, rasped and polished) to bridge the distance between the nb heatsink and the 2nd cooler and also used some nonconducting thermal paste and some pads. The second fan gets the power by the 5V PINs of the mainboard as the original nb fan. The system looks terrible, but works fine. The temperatures are about 5°C lower (ca. 85°C) at full load and 3.2 GHz:

 

I've ordered a card at aliexpress like ergoon has. Now I have a plan to repeat soldering operations and get normally working hd4650 on my 5920g. Could anybody help me with getting ROM for it? All the links I've found here are dead.

 

@ AlexCos: Welcome! :hi2: I did not order the card at aliexpress. I have no experiences with that supplier, but you can tell me yours. I hope you get the correct model. - Actually, I got my card(s) from ebay by HQ Computers. - That's no advertisement, in fact, I think, that information could be essentially: Jacek - their service specialist - was very helpful. He even sent me a flashed EEPROM in addition to my card and helped to remove the metal frame of the card and checked the card twice.

How good are you at soldering SMD elements? Though, it was a hard way for me to get my card working. I damaged my first card, I don't want to conceal that. You can read it at the first page.

Here is the ROM file for the MXM2 Toshiba DDR3 1 GB version (by .NetRolller 3D). I have also the modded videoBIOS files and a working HP vBIOS by triturbo posted at this thread, but for the start you should use this version: View attachment HD4650DDR3.zip

Be careful, modding your sBIOS could damage your notebook! No guaranties!
I also changed the system BIOS to the MXM corrected version of my ACER before I started the project. That could be optional. See page http://forum.notebookreview.com/acer/575866-acer-mxm-bios-mods-discussion-x920g-vs-9600m-gt.html for more information. - There are also problems with the links. Here is the systemBIOS file: View attachment 5920G_MXM_V3.zip

Please keep me informed about your progress and be careful, as I learned the hard way! I'll keep my fingers crossed for you!

 

@ ergoon:
Thanks a lot for firmware files. Actually, english is not my native language so there can be some mistakes in expression of my thoughts I'm from Russia.

Aliexpress is something like ebay with most of suppliers from China. I've found there an interesting and not expensive offer of HD4650. Here is it HD4650 M96 1G 216 0729042 K00005001 WK910 K LS 5001P KSKAE MXM II DDR3 VGA Video Card for TOSHIBA A500 L500 L550 laptop-in Graphics Cards from Computer & Networking on Aliexpress.com

In order to find out how can I make it work I've got to this thread. Photo and description matches with yours so I decided that I can repeat your experience as well. I will lie if I said that soldering SMD components is my everyday routine, but I had such kind of experience before. At least, I have a heat gun which can help

Since I've purchased my order recently, delivering will take a month or more. Anyway early or late I'll tell you the story about my process.

 

@AlexCos: Добрый день! The best known Russian word is "Достопримечательности". Am I right? I'm not a native English speaker and not an engineer. - That's why, I prepared a lot of pictures at this thread. Just ask, if there is a problem to understand something. - You are right cheap offers can be found there, but buying from China might be a problem in some rare cases as you can get trouble to enforce your rights, just in case of problems (e.g. a damaged product). Normally, everything should run fine and of course one can always contact the seller, ask some questions and check the rating.

So you have more soldering experience than me! Found some nice youtube soldering videos, e. g.:
Solder 54pin ram chip with hotair only - YouTube

CU!

 

Hello everyone!
Even though i don't write here often, i watch this forum quite often and find many interesting and useful things. But now i have some problems and felt like i need to ask a few questions. I hope i picked the right thread.

I am a Compal IFL90 owner and my 8600M GT died. I baked it about 4 times now and its starting to show artifacts. So i rushed to buy a replacement. I ordered Toshiba 4570 in belief that it would work. But it didn't. The layout seem identical to the one on ergoon's pictures. From reading this thread i gathered that i need to:
1. solder an EEPROM chip on the front side of the board
2. solder 3x 10kOhm on the back side on the @A position and left and right of it
3. flash EEPROM with an ACER vBIOS?

Tell me if i got things right?

Thank you

 

@black_stormy: I don't have baking exp. for graphic cards. .NetRolller 3D posted the information for soldering my HD4650 and he confirmed, the soldering manual was originally for a HD4570. You need the following things:

1. A M25P05A or M25P10A SOIC8 EEPROM chip.
2. A Bios for the Toshiba HD4570 card, see EDIT.
3. Three 10 KOhm resistors (SMD or classic style).
4. Soldering experience for SMD elements. - I was using conducting color to secure the PIN connections and two component glue at the body of the EEPROM, but I guess, that is not a perfect solution for everyone.
5. A (DOS) system to blind flash the BIOS (or a programmer to "hard flash")

There are two ways to get the job done. Soldering the three resistor bridges at the back of the card OR soldering the resistors directly to the PINs of the EEPROM. Way one is for pros, way two is easier for beginners. Look at the pics and at your HD4570 card, that should make it clear:



Be careful, I damaged one card.
I am not sure, if that way works for a Compal IFL90 nb too.

EDIT: View attachment HD4570DDR3.zip ... this is a vBIOS for a HD4570 DDR3 card, originally posted by .NetRolller 3D. The links were down, so this is a repost.

Just tell me, if you need more assistance.

 

I'm assuming that this will work for all acer models? I would like to stick one of these bad boys into my as6920g.

Will my heatsink work? Or will I have to make one?

From what I have read... Sounds like u got it right.

 

I've read your signature: Congrats to your "Sager NP-8170". Impressive system! :thumbsup:

I don't know, if there are problems with other Acer nb. .NetRolller 3D examined the MXM structure for a lot of the Acer computers and corrected the MXM structure at system BIOS level (see http://forum.notebookreview.com/acer/575866-acer-mxm-bios-mods-discussion-x920g-vs-9600m-gt.html). That was important for a "GeForce 9600M GT" card.

I added an additional heatsink at the back(!) of my card and used a thin thermal pad and some non conducting paste as a spacer, because the native cooling of my 5920G is not the best and the temperatures were a bit too high at stresstesting:

 

Thanks

I am using .NetRoller 3D's bios with my 9600m gt now, which was a nice little upgrade from the 9500m gs. I really didn't have any problems installing that one, except I had to blind flash another video bios when it was all said and done.

The cooling on the 6920g is nothing short of awesome! With a max temp of 65c with the 9600m I think it could cool just about any card that would fit. (I really want to find a 330m but I know I won't) I can get a 230m pretty easily, but not sure if I should go for that or a HD4650. It seems the Radeon card benches a little higher, but as I love to overclock, the 230m might be the better choice.

*edit* if you are interested, here is the video of me installing the 9600m

 

@ergoon: i have 2 problems to consider. first is where to get the m25p10-a. as i live behind gods back, need a store that is willing to ship to this part of europe.

second is that i dont know how to blind flash. i guess i would have to make a bootable dos usb drive. after that i dont know what to do. is there any way i can get an inexpensive preprogrammed chip?

 

Hi black_stormy! I have got a programmed EEPROM by the seller of my HD4650 card ( HQ Computers), you can buy such stuff at Farnell, RS Components, Eibtron, Distrelec Schuricht etc., but the delivery charges could be higher than the cost of the chip OR does this link help you? - m25p10-a - Mercateo -- Please send me a PM for a contact, maybe there there is a chip left at my box or I can give you the contact to Jacek of HQ Computers. He programmed a chip for me in addition to my card.

BTW: Are you a soldering pro? - It was very hard for me to get the job done.

Making a bootable DOS USB disk is the right way. Do you have a working MXM card for your nb? That would make it easier to setup and test the flash system with the working card. I added some commands to the autoexec.bat and some beep markers, who tell me the status of the blind flashing. You need to add the tool ATIFlash (I used v3.99) to the Dos system and run it: ATIFLASH.EXE -f -p 0 VBIOS.ROMI will try to help you, if you got a chip... programmed or not.

 

I have watched your video. Nicely done! :thumbsup: - I can see, the chip of the graphic card is on the other side compared to my Acer 5920G. That makes the cooling much easier for you. Do you have some more information about the cards you mentioned: 330m, 230m? Are they easier to overclock compared towards a HD4650 or HD4670? How powerful are they?

 

I am a nvidia fanboy, so this may be somewhat biased...

As in easy to overclock, they are both about the same, as long as they are older cards. Nvidia drivers are always better, from what I have seen. I have helped quite a few of my friends overclock their laptop GPUs and have had a much better time overclocking nvidia cards than radeon cards. I always find the max overclock and then pull back down a good 15-100mhz depending on what I think is best, or what the temps are. I do most of my testing with Furmark, OCCT, and Crysis gpu benchmark, and monitor the temps closely with something like CPUID hardware monitor.

I usually flash the clocks to the video bios when I'm done so I won't have to worry about driver upgrades, or upgrades to an overclocking program such as msi afterburner.

 

One important difference is that the 330M is 40nm, while the 4650M is 55nm. This can be felt quite strongly in the temperatures.

 

@ajbutch123 and .NetRolller 3D: Wishing a good start to the "13" and thx for the gpu info. At the moment I have no preferences for choosing Nvidia or ATI/AMD, but I would agree to the driver quality. Some years ago, I thought ATI has forgotten their Win and Linux users. -- I often installed the modded OmegaDrivers at Win. --- I liked my very old 3dfx voodoo Guillemot Maxi Gamer (NVidia?!) card. I guess, that is no option for gamers in 2013. ((-;

 

Hi everyone.
I've got my HD 4650 today. It was delivered from China. The same design as on ergoons photo. Chinese guys had put into the package some useful stuff like thermal pads, heatsink and a copper plate (15x15x1mm). Now I need some time for experiments. I'll post my impressions later.

 

Cool! I'll keep my fingers crossed for you! Just nice to hear that somebody is accepting the challenge! Let's go...

 

I've soldered resistors on the back side, then flashed vBIOS to the M25P05A chip through the self-made programmer (SPI programmer on LPT port). Chip was taken from old Radeon 9500 desktop graphics card. Now it works Drivers are installed and I can even play games.
But there is one problem. When it goes to the welcome screen, backlight turns off. I can enable it by sequently pressing Fn+left and Fn+F6 combinations, but it is rather inconvenient After enabling the backlight I have a situation when pressing Fn+left affects brightness decrease, but pressing Fn+right has no affect. After reboot I can see the BIOS screen, but when it goes to the welcome screen, my trouble repeats again. Everithing is fine, when I uninstall ATI drivers and OS works with standard VGA adapter. Could anyone help me with backlight? My OS is Windows XP. I tried many versions of ATI drivers without effect.

P.S. I'll surely describe my experience in soldering and flashing. But later.

 

I solved my problem. Everything is fine under Windows 7.

 

@AlexCos: Respect, well done!

 

Here is my story. First of all l received a package. You can see how it looks:

And inside:

Here is graphics card:

And some usefull stuff:

thermal pads, 1mm thick copper shim and thermal compound.

Then I took my old desktop radeon 9500 card

As you can see, it is useless without memory chips

 

Only one thing had attracted me on this card

Video BIOS chip M25P05AV.

And I'd desoldered it

with the help of heat gun.

Standalone version


Afterall I put it on my board and soldered it with the soldering iron.

I hadn't made the photo after I used the heat gun, but I can say that after heat-gunning I've got better looking contacts.

 

The same thing with these resistors:

The thin copper wire you see on the picture was just an useless experiment, you shouldn't care about it. The final version goes without it.

If I had an empty flash-memory chip, I could do a blind-flashing operation. In my case (with radeon 9500 firmware onboard) I had to use external flashing device. After that I've found the solution with "spipgm" program. Here is the developer's site: RayeR's homepage/Programming. This program works under DOS, Windows from 9x to Win7 and Linux and supports flashing via LPT port, so one need a desktop PC. Here is the schematics for needed hardware http://rayer.g6.cz/elektro/spipgm/spipgm.gif. And this is my solution

The brown connector is for power supply.
This is my do-it-yourself power supply unit:

LD1117 detail was soldered out from beloved radeon9500. The unit gives 3.14Volt output, which is good enough for flashing.

So, after flashing, soldering, assemblying, installing Win7 I can enjoy the new power of my laptop.
Big thanks to Ergoon and his helpers for such a good idea for upgrade.

 

@AlexCos: That's a very cool story! Very informative pics! THX! - Sorry for my late reply, there are a lot other projects and things to do. - Your posts take this modding thread to a new level. - You are a pro :thumbsup:

 

Hi ergoon,

It’s been a long time since I read threads like this. You have my deep respect for the good work you did.

The thread is one of the best for me :thumbsup:!

 

@duhai: I appreciate your kind words! - Actually, I don't deserve it. It is just a small project and I learned a lot things by reading and collecting the information of other threads. -- If you plan to modify a HD4650, I will keep my fingers crossed for you! My construction is still working fine and the postings of AlexCos show an alternative way to do the mod. -- Be careful: PLEASE DO NOT add one more card to your dead-graphic-card-list. Three are enough! -- I am happy, that some users still find this project.

 

You are extremely modest about your work and I like that. BTW it is too late for you to get rid of my gratitude because you are the reason for my decision to make the mod .

I asked Angel (he is like triturbo in the C90S world) for his opinion and advice. He surprised me with an EEPROM programmed with the right vBIOS ready for soldering on Toshiba 4650-1G-DDR3-Hynix and some additional bits. I tell him that I would like to know how to program the chip by myself on my laptop . He promised me to show how to do that with all details in pictures.

As far as the AlexCos’s way it seems too complicated for me . I am curious to see Angel’s pictures too and then I will start the procedure. It’s relaxing to know that there are guys successfully performed already the mod and sharing their results :thumbsup:!

Thank you for the support! I promise to be gentle with the 4650 .
We are living in a 4 Dimensional world and 4D video card is something natural .
I prefer to stay in 3D mode.

 

@duhai: Fine, looking forward to the pictures of your modding project. It's always nice to see, that the nbr users are helping each other to do such things successfully. Are Angel's pictures online? Searching for ............ BTW: Who knows, how many dimensions are the right answer: 3D+1D+?D. There are some models out there, postulating much more of them. :GEEK:

 

That is a great job, that you have done! Very impressive.

But I don`t understand only one thing - why you are soldering resistors for the inputs of ROM chip? Does it is required for this chip by its manual? For example - I`m planing to by HD6770M romless, but it has other rom chip. On its manual there is no schematic, that shows the necessarity of resistors.

 

@propolkin: You need appropriate instructions for your special card and chip. It will not work to use this manual. - I am not an electrical engineer. I can't tell you the details. - I have checked the following: The HD4650 card isn't working without the resistors.

The user .NetRolller 3D posted the solution for this special card with this special chip and that's why I used his modding manual; "the alternative way":

Cheers!

 

Latest cooling mod. I had some problems with the temperatures of my old Acer 5920G with the HD4650-GPU and X9100-CPU. That's why, I added one more cooling system. It is not as "cool" as triturbos solution - see http://forum.notebookreview.com/not...tom-builds/569783-5920g-cooling-overhaul.html - but works too (physical and psychological):

 

Hello everyone, i want to thank you for the work you have done on the subject and the heap of information the community has accumulated on breathing new life on mxm II laptops. On to the problem at hand now. I have a romless toshiba HD4650 with 1GB DDR3 Hynix memory from a toshiba satellite l550 that i would to reuse on an acer 5920g. I found it hard to find a M25P05A/10A but recently a radeon 9600 came into my hands. Inspired by AlexCos work i would like to know if it is possible to reflash the radeon 9600 inline from an old computer with an agp port with the hd4650 bios and then remove the chip and the resistors from underneath(just tested them, they are 3x10kOhm resistors!) and solder them to my card. Kudos.

 

@pchatzop: Very interesting idea. Maybe you can post the detailed specifications of your radeon 9600 card, so the pros can take a look...

Do I understand correctly? - You plan to boot into a flashing environment and force a flash with the "wrong" HD4650 bios, because you don't like the blind flashing option and have no programmer? -- Your card will not work anymore after that procedure. -- Then, you desolder the vbios chip and the resistors and mount them to the hd4650. -- There could be a kind of ID check, to prevent flashing the completely wrong vbios to the card. -- I cannot give the final answer, but I found a lot of threads dealing with flashing the wrong bios to a card. Example:

I flashed my 5970 wrong! - techPowerUp! Forums

 

Blind flashing is impossible, as AlexCos has stated, because the 9600 vbios will prevent the laptop from booting up at all(as opposed to an empty chip, that allow for the laptop to boot albeit with a black screen, but still allow bling-flashing). I can make a programmer myself but would prefer the easier way of just software flashing the card in dos and then desoldering the chip and resistors and putting them in my hd4650. The primary obstacle in my endeavor is sourcing a M25P05A/10A without costing me an arm and a leg, and AlexCos gave me the idea of reusing an old's card vbios chip for the project. I will probably go for it at some point soon and tell you how it goes. The 9600 card does not even work properly(works only in safe mode in low resolution, probably bga chip failure) so using it for the project would be a godsend.
EDIT: If someone where to send me a close up photo of a M25P05A/10A to check if the chip on the old card is compatible, it would be great. Regards.

 

@pchatzop: Ok, take a look at the chips - some good and some badly damaged parts - and some more info (the unit of the scale is cm --- 1 inch = 2.54 cm):

 

Sadly, my cards have the kind of bios chip suited for gt 230/330 mods. I was unable to source a M25P05/10-A in my inventory, so it would be really convenient to send me some of your leftover chips,(i would cover the shipping charges and the cost of the chips) so i can continue the project. PM me for info if you are interested. Thanks for all your help.

 

there's nothing missing, I have the same toshiba, identical MXM card, this place is empty, and card is working on toshiba laptop. will try to make it working on acer 5920g soon^.^

 

You can try to include the vBIOS in the sBIOS as described in this topic. Basically all you have to do is open the sBIOS in Phoenix BIOS Editor, place the vBIOS in the "Option ROM" folder, save it, and then flash it. For more in-depth guidance check the thread.

You can use whichever method suits you better.

No hard feelings, ergoon

 

OMG, that would be a real cool solution for everybody without any soldering stuff! Good job! I will take a look at the given thread. So I could declare this thread closed.

 

---

IMPORTANT UPDATE 2013: "valuxin" suggested a mod of the bios WITHOUT soldering a chip (thx to "triturbo" for the link):

My question: Has anybody successfully completed the procedure with a romless HD4650 (or other cards)? It would be interesting to know!

Be careful, modding your sBIOS could damage your notebook! No guaranties!
Needed files, system bios for the 5920G and video bios for the HD4650: Posting #60

---

@pchatzop: Sorry, I can't PM you until you have enough nbr messages, but maybe the sBIOS mod could be a solution for you. Be careful, I haven't checked that way. You should ask valuxin for more information.

 

After a lot of time, i came across the card , and thought about giving it a shot again. I did the sbios bios as valuxin suggested, integrating hd4650ddr3.rom as oprom2 in the Option ROM in netroller3d 5920g_mxm_v3 bios using phoenix bios editor pro 2.2.1.3 . It worked with both the (reflowed) 8600 gt and with the romless toshiba 4650 card . So it may seem ergoon work was for nothing, but it may still pave the way of using these cards on other mxm laptops where sbios mods are risky or impossible. This thread can really close now as we really have exhausted all possible ways on making these niche cards working on the 5920g and similar laptops. Thanks everyone for your input and your contribution to the community.

 

I should also add, this paves the way for the ultimate 5920g upgrade, the peculiar shaped 360m gts from asus. Integrating its vbios into the sbios could bring it down to plug and play level, and create the world's first 2007 laptop with a 2010 GDDR5 gpu! Thanks to the 5920g's heatsink peculiar inverted shape, it should require no trimming at all to fit this beast. Now if someone were to take the plunge...
