L702x Modded GPU BIOS

I didnt changed any default setting value at the modded bios, the modded bios have the same settings than the original one by default, however my modded bios allow some locked/hidden settings to be changed.

thats why I suggested thim to try loading default settings at the BIOS setup, it usually fix things when people mess with some advanced bios options

 

Still he or someone else could've changed the setting in his previous bios, so then when your bios gets loaded with default the setting is different from what it was before. And if that is the case, windows will behave exactly as he described.

 

I think all settings are reseted by default while flashing the new bios, specially because while flashing my modded bios I use the /CVAR flashing parameter wich manually clear all the settings ^^

however, to ensure it isnt related with custom settings, I suggest he go to the bios setup, try to load default settings, save and start the system with default BIOS settings

 

haha yes, my point is that before flashing your bios he could've had changed the default setting (i think is AHCI) to IDE (before installing windows). Then when your bios loaded defaults while flashing and it set it to default (AHCI). So if he installed his previous windows with customized setting then the default would be actually bad for his windows installation. He could install windows with this setting and then it should work anyway, but to make sure this is the issue i'd recommend changing that particular setting first.

BTW, i swing by 127.0.0.1 almost every day, and yet i never see you there

 

yeah,you are right, that could be too, but It is very rare someone change AHCI to IDE without a reason, also AHCI is better as far I know, it should be only set to IDE for compatibility reasons.

haha, never expected someone noticed about the 127.0.0.1 address on my profile

 

127.0.0.1 very funny indeed!!!!!!!!!!

 

Hi guys
Thank's at all! I've changeed the settings AHCI/IDE and now the XPS Work fine!... with GPU Clocks stable at 800/1080MHz!!!... with more 28/30% performance!
Great Job capitankasar!!!

 

Glad that it works fine now One note though, as capitankasar said, IDE is used mostly for compatibility and it's better to have a windows installation working on AHCI. In order to to that you have to reinstall windows from scratch (after changing the setting to AHCI in bios), or use a guide like this:
How to Switch from IDE to AHCI without repairing/reinstalling windows - Neowin Forums

@capitankasar I finally got my 1600mhz ram and installed your bios mod, everything works like a charm One question though - voltages behaviour on GPU didn't seem to change. Can you point me to what I should be looking for? And one more question: you advise to enable fast strings setting, can you tell me what it does? (EDIT: I found that link: http://www.bios-mods.com/blog/unlocked-motherboards/2012/12/bios-spotlight-uefi-dell-xps-15z-l511z/ , where a lot of unlocked functions are explained )

Since I will be reinstalling windows in order to use 32gb ram (instead of 16gb) is it worth reinstalling in UEFI mode?


Thanks and once again big thumbs up for your work

 

@fixdgchd

well, I didnt change the voltages by myself, I just picked the GPU bioses Sharadeos modded and made a version of the modded bios with sharadeos' GPU bioses, I supose it works, but cant confirm, I also dont have a XPS 17 to test ^^

try using HWmonitor to test the voltages, take two reads, one while the system is iddle, and another one when you are gamming (alt+tab or playing in a window)

mmm, I dont think windows reinstall is needed just for a ram upgrade, it probably will just detect the new ram and will be ok

as for install in UEFI mode, mmm I remember the L502X users had some issues with that.

it seems the UEFI support for this laptop is limited and it have some issues, I remember people had issues with the function keys and stuff like that, if you want to test, give it a try, but you are warned if bugs appear later

oh, and thanks for your comment

 

do we have a new bios ? im using the advanced one though , i havnt been up to date with bioses,


do we have raid in bios now !? please let me know bcuz i search advanced bios with raid and modded gpu bios thx in advance

if thats the case , anyone thought about fancontroll options/support in bios ? to make it less anoying ^^:

 

@capitankasar

Thanks for the info - I need to reinstall cause I had win 7 home, so it sees only 16gb I guess I will give UEFI a pass, everything works for me now and I don't really need it. As for voltages, it seems the computer behaves exactly the same, but I don't mind since it was very overclockable before already. Can you tell me which version of change is in the bios you provided me with? What I mean exactly is what are the changes in this bios from stock. (under or overvolting and when)

Once again thanks for your help and terrific work

@WesleyNL
No, there's no new bios, it just took me this long to test drive the modded A19

 

so no raid enabled either ? bcuz i readed some posts ....

 

@fixdgchd

ah ok ^_^

in that case try installing win 7 ultimate x64 like I did, it have good stuff and have no limitations.

well, as for the changes, I made a small description of my changes over the stock bios.

relating the GPU changes, they are the changes sharadeos made to the GPUs

I picked the modded ones from his A17 BIOS at the first post but didnt touched anything else related with the GPUs











@WesleyNL

as far I know there are no sucessfull raid modded bios for the L702X or L502X, I tried something but without success, maybe someone else can get it working ^_^

 

ah ok, hey have you ever tried to change fan settings ?

 

I tried once on my L502X, but I noticed by just entering at the menu made monitoring software to crash and going too slow, I supose that was caused because it enabled some kind of unfinished or buggy alternate monitoring sensors.
I fixed it by loading default bios settings, and configure everything else, but keeping myself away from the thermal menus.

it was a little buggy at the L502X, not sure at the L702X

 

i find this 2 way speed step anoying
low and high watching a movie and fan turns on at max speed its like you get a heart attack, if i only could controll it with speed fan then i am happy but even that doesnt work, sometiles fan doesnt even know what to do it turns on/off everytime untill i reboot, what i also notices when pressing rightclick on desktopor when going to nvifdia controll panel the fan switch off for a sec and then turn on again at high speed

 

If I swap my 1333 ram with 1666 and of course change the bios to 1666 ram speed, will I see a noticeable improvement with 3d gaming? My laptop has a gt555m.

 

No such thing is 1666 Mhz,I believe you were trying to say 1866Mhz!!!No you wouldn't notice any performance increase in a game but will notice little performance increase among other Programs and benchmark!!!!!!!!!

 

Actually, I meant 1600. The ram is also shared by the video card so I thought perhaps it would help, but I'm guessing it's not really noticeable.

games dont relly on memory as far as i know , on 1080p the gt555m suck , mines was basicly a 900p but swapped to a non 3d 1080p screen and saw fps drpping by like 6-8 , ram speed is only noticeable if you actualy do memoy things like video encoding or a ram disk , byt games wont improve, besideds the gt555m have its own memory and aint shared, the video shared memory is for the internal gpu intell 3k this is howfar my knowledge brings me

 

actualy kingston suck , my corsair vengance do beter, could be my laptop,

 

I decided to upgrade my laptop memory from a Samsung m471b5273dh0-ch9 (1x4GB) memory module to a Corsair Vengeance 8GB (2x 4GB) 1866MHz DDR3 Memory Kit, benchmarks are below. I'm using the A19 modded bios + modded Nvidia vbioses. I'm using a non-3D L702x with a crucial m4 512GB SSD. Benchmark ideas are welcome.

does anyone know if I could have messed up something when I changed my palm rest? my CDrom shows an error code 19 in the device manager in windows 8. I tested another drive in the slot and I get the same error. so I know the Drive is ok.

edit: I also added 16gb of ram recently.

 

it most likely Window 8 problem!!!!!!!!!!!!!see if you can update firmware for the drive or try different drive....

 

yep I just used a windows 8 disk to boot from and it works fine out of windows 8. Im ready to loose windows 8. Windows 8 seemed pretty cook at first. but now I think its just a POS.

 

unlikely, palmrest only contains the mouse pad and a few btns, even if it could go wrong then the wrst you can get is that they dont work w/o windows knowing it ,

if the cdrom give error code then it means it doesnt support the os or oc dont support cdrom, dell is known for crap hardware afterall , dell is cheap performance

dell suck so much that the mechanics are from hp , dell support themselfs dont even know the xps series at all , well atleast here in the netherlands that is it gone wrong multiple times with replace parts, they see what device i have by its servicetag , and they send me L701x parts , i clearly tell them what part i need but either they dont listen or they dont read , so yeah i now order parts myself from ebay ... i swapped my screen to non3d 1080p from 900p , it works like a charm compare to old screen , fun thing is , when i bought it it had an samsung screen and it gotten dead pix so i let them fix it i got an philips in return, backlid died after a week, i was like i order my screen myself , and sofar this chinese brand does great, it even have more brightness to

i opened mines alot , every 2-3 months clean from dust i removed the dust filter from fan to incrase airflow

anyways it seems xps series are discontinued , no more driver updates or mods sadly

 

windows 8 suck more then 7 for me , i rather go linux mint if it was more powersaved

 

Any one was able to get the recovery disk working? Or do we have a working recovery method for the bios, incase something goes wrong, I would like to upgrade after making sure, i can recover if anything goes bad. I am too scared to open anything up, and dont have any expertise with hardware related stuff

 

I reinstalled windows 7 pro and all is well. Everything works perfect again. Win 8 is a joke. I'm glad I only paid 16$ for the upgrade disk. My CDROM works perfect as well as the rest of my power management.

 

To all that have overclocked the GPU for the l702x

Just wanted to ask you where you found the link for the Unlocked Bios for your l702x?
I tried using the one posted last november by capitankasar located here:
http://forum.notebookreview.com/dell-xps-studio-xps/641688-l702x-modded-gpu-bios-18.html

However my voltage on my GPU didn't seem to change. It wants to hang out at .8700.
I'm wondering if you used a different flash than i did.

Also, i see you are running it around the 800mhz range. How were you able to get it above 770mhz? *(using MSI Afterburner here)

 

I am glad it work for you!!!I am still using Vista 64 in my Desktop with very minimal issue with it!!!Window 8 is two step backward as far what I can see!!!!!!!!!!

Firstly,

Congratulations on a wonderful job to get UEFI to work on the L702X, A19

One problem, pressing Fn+F2 (with Windows 8 UEFI Installed using the A19 mod bios) I get a hang in Windows 8, just freezes. all other Fn keys work as intended. What could be the cause?

Thanks,

Jase

 

@hotjase

I suspect one of the reasons dell decided to disable Uefi was because the uefi was just partially done, as for the moment uefi installations with L502X and L702X laptops give some issues.

I noticed about more guys having freezing isues with the function keys on uefi installations at the L502X topic

as for the moment I dont have any fix, but maybe some other does

 

i dont use uefi snce i also run linux mint, and uefi blocks that

 

Could the Inspiron 17R SE UEFI 2.3 be transferred across to the L702x?

That bios has a UEFI/Legacy option instead of UEFI Enable, Legacy Enable.

I guess true UEFI implementation the UEFI bios will only be available within the OS like seen on the Samsung Series 9/Acer Aspire S7

 

From my research, there seems to be that the Function keys use BIOS calls to get functionality, where as UEFI uses ACPI, I guess only way around is to intercept the BIOS call and convert it to ACPI, how that is done I don't know

 

@hotjase

porting almost the whole firmware from another laptop will probably not posible, since it is coded for an especific machine, sadly, adding newer versions of UEFI to the machine is not posible without the manufacturer support.

about your other post,even it should be posible/easier I am not sure how to do it either.

my knowledge is pretty limited unlike most people believe over here.

your best chance is ask to the people of this topic

(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO

most of my progress with the bios mods couldnt be made without their help

 

Hello all. How has it been going in here. Just pooped in to see if there is any progress. I have had a few people email me about my setup and hoped it helped them achieve their goals. Any new modifications to the bios? I am about to do a new project on my XPS. Going to put a 2920xm in this bad boy to stop the bottleneck in the mem. And looking to turn this 17 3d display into touch as well.

so will there be more mods to bios l702x ? like adding functions or changes in fan speeds? adding raid if possible , dunno if you ppl still wanna continue l702 since its an old notebook and new geenrations took over

 

I still hope for the raid capabilities. It would be nice to have a dual ssd raid. This may be an older laptop but still blows most others out of the water.

well it seems the chip dont support raid, also yeah its a nice notebook, far more supperior in capabilities then any othher notebook for the price dell sell them, and sofar i only see dell have unlocked bioses now , dont know about other brands like msi/asus/bto exc.., a raid and fancontroll otion sothat you can controll it trough a program would be nice, though im thinking to switch over to msi bcuz it have msata+sata so meaning 3 ssd spots inside + fancontroll as far as i read

 

Just wanted to register to say thank you for the uefi support for the l702x. My only issue now is quickset won't install and using the FN-F2 option hangs the laptop. Other than that it's working great. I see you responded that no fix exists for this. I can live with that. UEFI is worth it.

One last question. my gpu has a bios version of 70.06.32.00.02. I noticed someone here had a .03 version. I can't find it anywhere. Any ideas?

Thanks again!

 

@all

as for me, there are no plans of relasing more bioses for the xps17, there arent any new researchs relating more unlocked features, people at the bios-mods forums seems inactive, and I have now less free time, I also have to focus at the XPS15 bios requests from my topic, so unless someone else have time and interest to keep tweaking the bios, I dont see so much progress in here.

keep in mind also sharadeos started this topic, and he became inactive at this topic when he sold his xps17 machine, a machine I NEVER had. so I couldnt test anything relating my mods.
all I did was replicate the mods I did on the l502x at the l702x latest bioses with sucessfull results, but nothing else.

@akajester

there are some issues with the uefi mode on windows 8, I suspect it is due incomplete uefi support, thats probably why dell disabled uefi on xps 15 and 17 models

as for the gpu bios versions, U supose that is why the l702x have many different motherboard with onboard GPUs
when I modded the xps 17 bios, I noticed up to 4 different nvidia bioses + the intel hd graphics bios.

the l502x have two nvidia bioses and the intel hd graphics bios inside the main BIOS
one for the 540m and another one for the 525m, that will probably the same history for the xps 17, with the 550m,555m card and maybe others.

also it is posible the video bios version got updated on newer bios updates, but I guess dell is too lazy for that, we noticed poor bios job on the laptop while comparing official bios updates at the l502x.
so I supose you have a different gpu board than the one you saw at that screenshot

 

Capitankasar, thanks again for everything you've done here and thank you for the information.
