Got around to modding the old G75VX

So i been doing a ton of mods on this thing some i will talk about later they are still in the process of being finished.


First up we got a bios mod. Unlocked pretty easy to do i uploaded a vid. Please not not all the option were unlocked but can be its pretty easy to do so. Main point in doing this for most people is to unlock the ability to set at what points your fans kick in and at what % of power they run at. You got 2 points for this.

Building on that i pulled the vbios and after a while in a hexeditior i was able to unlock it along with some other stuff. Bumping the max clock from 820mhz to 1,100 before the system just can not get enough power from the dinky little 180w psu. Using a 220w i was able to get more out of it but just a heads up this card can stuck some power and stock the cpu and gpu are taking up 120w alone at load. That gives you 60w for the rest of the system as well as your headroom for overclocking amusing the psu is giving out a full 180w what its not unless you got lucky. Expect the 160's on the low 170's on the high.


Next mod is a requirement for a upcoming mod. This involves relocating the SATA connectors closer to the top of the case "Towards the keyboard". Pretty simple mod and when you look at it you will see what needs to be done pretty easy. This was so i could get more space on top of my drives. Removed the OCZ Vectors from their cases and used some small heat sinks with some thermal epoxy to mount them to the controller. Then used some 3m 2 sided tape to hold them in place since i no longer have mounts. In there pretty solid. Key here is low profile. Ended up with the room i needed for the mod that this is for. SSD's run perfect


I'll update as i do more and what i do. Also toss in some pics and screenshots.




Please dont ask me to unlock your bios or for my modded vbios. I dont really care how high of skill level you are if you brick your system i dont want you to come crying to me saying i gave you a corrupt file.


Been toying around with the idea of some stuff. One is to improve cooling by adding a passive heatsink to the GPU since Asus was cheap and used a craptastic 2 heat pipe system. Main goal is not to greatly improve cooling but add a little cooling by sucking some heat off the heatsink and dumping it into a heatsink.

I got some heat pipes that will work as well as some solder. I gutted a old 9800GT heatsink so i got all the fins it will be close i might have to trim them 1-2m to get it to fit in but it should be a nice fit and help dissipate some heat. Will require notching out some of the case but nothing major. No idea on if this will drop the temps at all or 1-10c but its worth a shot. Will be losing one hdd bay since that will be a heatsink but i got a idea on how to stack 2 SSd's in the other bay without the housings so it should all work out just dont know how well. If it works out good i'll get some part numbers from the heatsinks i took the pipes from and work up a guide.

 

If your not willing to share then what's the point in flaunting it?

 

Letting people know it can be done. Really why should i upload a file 9/10 people wont have any idea what to do with it and they will attempt to use it and brick their system then start crying to me because they screwed their system up. This is a list of what i'm doing not a step by step let me hold your hand guide. Just because im doing and posting a list of what i do does not mean i have to post step by step tuts on how to do them and provide 24/7 in home support on them. This is not a guide its just a list of what i'm doing and have done and what can be done if you do your research.

 

The hell we need a mod for if the gtx 670mx default power is more than enough for mosr gaming needs unless this mod brings it close to a gtx 680m speeds. Does it?

 

Well overclocked the GTX 670mx does get close however maxed out wow on a stock GTX 670mx with 8x MSAA does bring this system to the low 20's in some parts.

Now for some good news.

GTX 680m installed, working and running like a champ.

Now for the bad news.

Tons of cutting must be done to get this to fit in the case.
You lose both HDD bars but you are able to mod the bays so you can use a SSD with no housing.
Overclocking if very limited due to the fact the psu is crap and low power.
Custom heatsink must be made using the stock heatsink and pipes.

Tested it outside the case and it ran pretty nice. Now its just going to be a matter of cutting and fitting it in the case as well as making a custom heatsink but good thing im pretty good at removing heatpipes now. The first few years ago got to hot and boom. Wont post how to do this just because of how hard it is in terms of getting it to fit and rigging up a cooling solution. This weekend i'll be doing some cutting and i hope get it in the system so i can start to work on the heatsink. By then my 330w psu should be here.


Side note Kingston HyperX 2133mhz ram is working with the modded bios.


So what is the cost to make the world fastest G75VX?

$1250 for the VX
$750 for the GTX 680m "Spare card i had in case one of them die on my main system.
$100 for the heatsink to use for the mods. Have not ordered this yet.
$180 for the 16gigs of DDR3 2133
$239 for the Samsung 840 pro
$100 for the psu
$750 I7 3920ES "Might be cheaper now bought mine a week after mobile ivy was released."

Total price. $3369 not including the hours spent modding it. I'm keeping a work log so i'll post how long it took to get the GTX 680m in it. And as you can see the full price is more expensive for other brands with the same specs.


Update on the cooling mod for the stock GTX 670mx that's got pushed back until the new bottom gets here off ebay. swapping gpu's is a higher priority to me and i needed another bottom in case i cut to much so i just decided to put that on the back burner.



Now for a tease. Note the system was out of its case and the GTX 680m was using a heatsink off my main laptop with desktop 120mm fan blowing at the heatsink. It was a fresh install so i was limited to programs on a flash drive. I'll put some gpuz and what not after i get it all installed. But i did not have any wifi on it and i use my phone as a hotspot so i have no way to get internet to it other then wifi. Should have some progress made beginning of next week but till then. here is a little tease shot. And i did not run furmark because i just did not want it sitting like it was for to long and running. It was kinda ghetto.


And to answer the $3300 question. Why would i do this? well because i can sell it to a fanboy when i'm done and get more then what i payed for it and then pick up a MX17 when the GTX 7XX come out

 

Damn Bignaz, you must have a lot of time on your hands for this type of project lol. But anyway as long as it's fun to do then it's all good and maybe you can make a lil money down the road for it.

I'm actually thinkin about pickin up the G75VX at best buy for around $1,330 after tax and I dunno if i should do it or should I go for the MSI GT70 with a 670mx also which is for sale at xoticpc and bhphotovideo for $1,399. What do you think

 

What this boils down to is are the features the GT70 have worth $69. To me they are. You get a better kb, better backlight on the kb, better sound, ability to upgrade the gpu without having to do a super mod like i have to on the G75 that not only takes time and money. extra usb port or a total of 5. and the GT70 has a 9 cell battery vs the G75's 8. Also MSI are much better with RMA's and warranty work. To me hands down the GT70 is the better buy and if i had to pick i would pick the GT70 and never look back. That $69 goes a long ways in terms of extra details. Also from what i been seeing the GTX 670mx's have been clocking higher in the MSI's then the Asus's. But if i have to pick i pick the MSI. Just go ahead and look at the ports and what not if it is something you need or want then get the MSI but if the ports dont really matter to you, Can deal with bad cust. service then the G75VX is not to bad. The $69 can be saved up and that can turn into a SSD pretty fast.

 

Great work! +rep

This is a huge step forward, proving that a GPU upgrade in the G75VX is doable. For now I just have two questions:

- would a 7970 work instead of the 680?
- it's not clear for me if the bios modification is absolutely necessarily for the new GPU to work? Basically if you manage to do the case fit modifications and adapt the cooling for it, the new GPU should just work plug and play?

 

I wont go into to many details about it at this time. I dont know if any other cards will work other then the one i tested. To be honest this is not something that most people can do. The only way to do the cooling system for the card is to remove the stock heat pipes off the stock heatsink then put those on a heatsink for that card. If you do not do it right the temps can be very bad or you can heat up a pipe so much it blows apart.

Can you do the upgrade? Yes. Is it practical? God no. For the price of the VX with a GTX 680m, heatsink to mod you can just buy a system with a GTX 680m that you can just plug in any mobile gpu you want without doing extreme case mods to fit it. Asus really went out of their way to keep you from being able to upgrade the gpu why keeping the cost down for them self. Doing the modded forces you to use a SSD that you mod to fit in the now limited space or convert the optical drive to a hdd bay. Really the G75 is what it is. The one time use camera of gaming laptops. It was never meant to be upgraded outside the ram and hdd's and if you need more power they expect you to buy the next version of it.

Getting a GTX 680m in it will run you at least $800and require some work hours. For that price it moves the G75VX price from $1250 to $2050 what for that price you can get much much better systems. Maybe if the system did not require modding to as many things it would not be that bad of a job to do the swap but right now you need to cut the case, mod the heatsink, mod the SATA connectors to lower then make your SSD'S thinner by removing them from the housings. And that's just what needs to be done to get it to fit. Im debating wither or not to even go ahead and post more info on this or a guide because theirs so many ways you can screw something up and end up costing a few hundred to fix, I'll see how well the whole process goes and make my decision then.

 

You need more then 150°C to blow the heatpipe. I used a heatgun to mod my JH heatsink to work with the alienware one and soldered it using temps over 500 °C. Yes the pipe is cooling the heat but I did test how much the pipe could handle. The solder on the radiator started melting and just about 230 °C the pipe started expanding. You will find out that getting old parts off is easy but soldering new on will be a pain in the ...

Also if you heat the heatsink to much the copper plate that is on the core.....well it will just fall off and you will have to solder it back again. Happond to me the first time i did the mod.

I think testing with the same brand GPU is the way to go as the geforce GPU did not work in G73JH eihter.

 

It's absolutely true that this is not practical in any way at the moment. The VX has a fair price in my opinion and I would only consider such an upgrade mod after a year or so when it's out of warranty and the resale value is too low. Also maybe we'll be able to use at that time some even faster GPUs.

On a personal note, I also agree that for about 2k there are much better machines out there, heck I would be ready now to buy one, but each of them has some dealbreaker issue in my eyes (AWs stupid mirror screen, Sager/Clevo design and maybe questionable build quality, MSI - I just don't like how they look, toy-ish).

 

The MSI retail series are now brushed aluminium finished, they look and feel very nice and actually properly reward tweaking efforts like this as while they are interesting, pretty much any other brand of $2000 machine will annihilate yours.

 

Honestly when that time comes the GTX 680m will be matched by any mid end card and its just better off selling the VX for $500 and spending another $500 and buying a new system.

Oh yeah but i have been a big pusher that the price for any G75 should be $1250 any more and there just way better systems out there. I mean the system just docent have anything other then basic bare bone stuff. But i had a GTX 680m sitting here as a back up so i said why not. Slap my extra parts i got in the system here and just pay for the SSD's and sell it on ebay. Someone will buy it. No way i would ever sink the $600-700 into this system for the card. Its just not worth it.


Really i got my main laptop that i game on this was just a system i wanted to test out the 670MX and the price was right so i figure i would give it a shot then slap some crap in it and sell it off. But for $1250 with the MX i will say its a sold value. The 670MX gets mean after about 850mhz on the core. But sadly its just playing cachup to the $2000,$2500 systems at that point. But i have gotten the 670mx pulling the same numbers as a stock 680m so that's not to bad for a $1250 note book.


As for modding the heatpipes. Yeah i used a blow torch and burst one lol. Now i just take them to work and run them in our reflow oven and they come right off. Then i just re solder them at a rework station. So unless you know what your doing and or have the right equipment to do this stuff. Its hard im lucky enough that i can just take it to work and in 15 min have the pipes off and 5min after that have new ones installed.


Will say i have gotten some off with a blow torch in the past without the pipes expanding or any damage but i did blow 2 of them and they are like very small pipe bombs and when they go off you can get some metal in your eyes or burns. But when they went off for me all i got was a poop stain in my pants.

 

Just a small update.

Case is cut got it all fitting in. Just gotta lower the sata ports now so i can drop in a ssd lower to the case. Easy mod for that. Monday i'll be setting up the heatsink. Since i have it mounted and all that i can see what i have to do with the heat pipes then i can finish the heatsink and should be able to do some testing some times next week as soon as y new PSU gets here.


CPU was not supported so guess i'll have to address that issue but it should not be to hard.


Also last run on the GTX 670mx that i done for a while without a volt mod.

I'll get some max clocks with the volt mod at the end of the month.

 

Funny that there is not a huge disparity between the 670MX and 675MX even when both are overclocked.

 

Oh yeah that GTX 670MX you can oc the memory to make up for that 192bit buss pretty each.


Ok update.


Finishing up the heatsink. Decided to add a 3rd pipe to the heatsink and add my passive heatsink to one of the HDD bays. Waiting for the rest of the parts i need to get here and i might see if i can add a small fan to that heasink if not its worth a shot. Might consider using the ssd in the optical bay then in one of the bays for the HDD use a single slot GPU fan blowing across into a heatsink then ducting it out a vent in the bottom cover i'll cut out. Still tossing around some ideas i wanna do it right and get the most cooling i can on the GTX 680m to see how hard i can push it in this laptop.


On the upside i got a machinist at my work to do all the milling for me. Case it done and looks pretty good. They send out the wrong PSU to me to. Its a 330 but wrong tip so i'll be getting a replacement sent out soon as i don't want to chop off the tip and change it since i'll be selling this laptop when its done.


Side note i really wish Asus was not so cheap and hell bent on limiting features in the G series and would of put a MSATA port in the thing. I mean how many corners do you really need to cut the G series was all ready damn circle from it.

 

680M really does step up the heat production, just to warn you Performance too though.

 

Should post some photos, would love to see progress. !

 

Asus are really funny about which features to include, they stop caching from working on chipsets that support it that have mSATA slots, so it can be really odd.

 

I know my main system is rocking 2 of them lol. Thats why im trying to plan for some 85c load temps since the G75's cooling system is nothing amazing like fan boys will tell you.


Who process is being documented as well as part numbers and hours it took to do what. After i get the cooling all set up i'll be hooking it up to some equipment "O scopes and what not" to see how the power circuits handle the GTX 680m. Should handle it at stock fine but who knows its a Asus so i might find yet another corner they cut in the qualty of components used for this and start blowing out parts.

 

I would get a copper plate and have it milled to the same shape as the geforce cards have and then solder heatpipes on that. Copper is not hard to mill and if you get the right heatsink to get the shap off of then you will get low temps.

You need something like this:



Had almost the same idea as you once with the 6970m. Maybe try it in the summer. Would use the HDD space for the cooling and then just get a copper heatsink and add the extra cooling for maximum OC

The cooler is off of a old Futjitsu siemens :Amilio notebook that had a desktop CPU in it and that was to keep it cool. I manage to salvage it form a computer graveyard If you want i can get the full model number of the notebook so can look for something similar

 

No progress on this? No pictures? Pics or never happened*

 

Yeah as soon as you OC you get increases of around 30W from it lol.

hi
request oc cpu n gpu to max utilize of 32gb ram and other resources,

anyone who may help

thanks

You need to get in touch with the right people for that sort of work, unlocked system bios (are there any options worth bothering with) and then GPU voltage and clock settings.

 

yup yup

will do

thanks

 

I Wonder why OP stopped updating his thread??

 

Usually life has a tendency of doing that

 

I have researched a bit and I believe this two guys are one and same person. And looks very much like he is just talking big but actualy shows little or nothing . It was specialy interesting to read page 2 in this thread: G75VX + 220w psu + OC = Need more power
So it looks his 680m ugrade was just wett dream .
But hei he can answer here if he does not agree and prove me wrong.

 

Guys, talking about mods, does anyone know how to steal a 12V source from the motherboard or the battery ? I am designing a fully internal water cooling system for the G75 and I WILL be showing you pics of how to do it and how it was done. But to move forward with the project I need a 12v source to hook up the motor of the custom slim pump that I designed.
Will get you with pics and updates faster if I know this.

 

12v rail is not usually there in a notebook. You may just have to put your own dc to dc off the main input

 

Lol.

If you were to attempt the OP's imaginary project, wouldn't it be better to carve up a VW instead?

Why get the higher spec version just to remove all the higher spec components?

 

These sorts of projects rely on what you have to hand usually.

 

I have an ASUS G75VX with an nVidia GTX670MX

I downloaded the AMIBCP ( Download amibcp mmtool.rar from Sendspace.com - send big files the easy way) and I changed the settings I want to be available from Default to USER but they aren't showing up still.

Do I need to choose Supervisor or Extended User? Or do I have to do anything else that I missed?
