Overclocking the 7800 Go GTX - Page 4

post #61 of 83
err bill i'm sorry but i cannot tell you if its safe or not i don't wanna be the bastard that told you its safe when you fried your card lol

it should be pretty safe though. the 7800go gtx seems to be downclocked by nvidia to assure its not overheating but it seems that every laptop cooling system is able to cool this baby down pretty well. so if your temps are fine now this flashing shouldnt be a problem. just dont overdo it. stick to something around 450/1200. that should be fine.

and codename i was kind and voted

thanks vollgasasi for the answer but if you please to help me for a little more.
1.How can i find my gpu temperature?PCWizard and Everest can only monitoring cpu and hd's
2.i made a new bios with Nibitor changes the clock and memery in 450/1200,does it needs to change and something else?
3.i had download the nvflash 5.25 can you tell me please how it's works?
Thanks again(and sorry it's first time to trying oc and i wan't to be sure for the steps i shall follow)

np bill
the gpu temp you can see with rivatuner. download it if you dont have it and look in hardware monitoring you can find the temp there.
to your secont point: dont change anything else. it's for experts or for guys that really wanna try their luck...
third point: i wrote a quick walktrough if you wanna call it on page 3 or 4 of this thread. either you read that or the readme. i don't know exactly what i did since i did the falshing some days ago. so i dont wanna tell you something thats not right. ok?
good luck

Thanks for the info and the tip. I've tried overclocking the Sager 9750's 7800GTX with amazing results. http://www.notebookforums.com/forums...d.php?t=125972

The bios of the 7800GTX in the 9750 isn't locked. I just downloaded the x64 81.89 drivers and performance modded .infs from laptop to go. I OCed through the driver interface to 456/ 1.21. Result...

7702. I haven't run a 3Dmark test from x86 with the standard drivers yet.

Again, the 9750's are NOT locked as you mentioned, this is a well known fact. The 5720 is and I believe it's because we got a bunch of cards that were originally intended for the XPS M170 since the two are so similar... See earlier post for more on this if you care. Nice score

I am probably going to Uber OC my 5720 this weekend and get my 7800 pulling 430-440c/1200m (No AS5, wanna be safe). We will see how things go, I may open it up and install a temperature probe on the GPU as well, we will see...

would it be possible to once flash the 9750's bios to the 5720's graphics card and then be free to software overclock all the time? are they compatible?

Well that's a very good question...

Believe it or not, I think it all may be heat related. The compact confines of the XPS M170/5720 warrant the GPU to be positioned right next to the CPU (Can't speak for the XPS, ONLY the 5720, though presumably they are similarly architected). As I have mentioned, this whole issue may boil down to RMA risks, which equal profit losses. This is a wild theory and does not hold much water from a technical standpoint other then a "What If" scenario. The scenario being, If the CPU FSB was OC'd along with the GPU, could the chassis design of the XPS/5720 efficiently deal with the heat? Would a potential "Heat soak" situation arise from the CPU/GPU being so close together? I think DELL/SAGER is just playing the ultra-conservative card to avoid RMA's and over-zealous OC'ers.

The 9750 has generous chassis confines (It has to because of a higher voltage chip and operating temps) and must deal with heat differently then the 5720. However, I feel this is not the reason for the ability to OC the 7800 in the 9750, the 5720 runs ICY cold. I feel its the positioning of the CPU/GPU in such a close proximity may be the purpose behind the GPU OC lock on the 5720.

Just my opinion...

codename: yea i also think its RMA related. i mean a bios lock is the only way to keep newbs from frying their cards.

well does anyone dare flashing their 7800 in the 5720 with the bios of the bigger brother? i dont wanna be the first one

evan stranger is the fact that some dell lappys can volt mod there cards , makeing them incredibly stable evan at very high oc. for those of you wondering how to flash video bios . heres it is i dont pretend im a guru or anything this is just from personal experiance 1/ create a bootable floppy disc with windows (mines a usb floppydrive, just click on my computer/right click floppy disc drive / format / create an ms dos start up disc. 2/ down load nvflash and unzip it and put it on your bootable disc 3/ download nibitor 2.6 . with nibitor open it up and click on the second tab which says read bios /choose and object (7800gtx go) then press read again accept choose read into nibitor. this is your current bios, now before you do anything choose your second tab again and select "read into file" and put that on your bootable disc, remember what you named the file and it has to be old dos naming scheme ie 8:3 eg msi66mod.rom accept you dont have to put the rom part on windoze does that automatically when you save it.now that disc is your backup disc should anything go bad and believe me make one it aint funny haveing a $700 paper wieght. now create another bootable disc put nv flash on there. 4/ if you want to mod your bios , just read/select object/7800gtx go/read/read into nibitor change what ever you want (i havent been very succesfull volt modding it crashes on windoze) my clocks were 430/1200 and they were stable on ati tool for 24 hours. also in your bios youll notice near the end where it says temp reading that there is a tab that reads 6800gt temp reading or something if you click this the latest ati tool can read your gpu temp.now that youve changed what you want go to adavanced tab which tells you bios gibberish and board number and press rescan then press the first tab then save , now once again make sure you remember what you named the file and it has to be standard dos character numbering ie 8 characters then 3 for the file extension "ie msi66mod.rom".then move that file onto your second boot disc.5/ now restart your machine press f2 and make sure your booting from your floppy drive then press save and exit bios. after a while youll come across a screen that says starting....... then windows mellinium , then A:\ prompt , at the prompt type " nvflash -4 -5 -6 filename.rom" without exclemation marks its say a whole heap of stuff then itll ask continue ? press y, then it will say complete or done or something. now remove your usb floppy drive then hard reset and boot into windows with your new video bios.********* if things go wrong ********** if things go wrong dont fret you made a backup remember so boot from your floppy insert your backup disc and reflash it back to the way it was if you forget what your file name was at a:\ prompt simply type "dir" and it will tell you all the files on the floppy.hope this was a help to you guys.

mickthemad: no offense but we already know how to flash yea even the clevo guys know how to do it :P but thanks! the problem with reflashing your original bios if something goes wrong is: if something goes really wrong and i mean really then you probably dont have a chance of flashing back because your screen stays black all the time and thats why we want a software solution.

If anybody could get the VGA BIOS from the 9750s I would have a look at them and could say if we could flash it.

And yes it is true, if your flashing goes realy, realy wrong then you wont have your screen to flash from, however that needs not to be the end, I've created an autoflash, meaning when I put it in my CD drive and the CD boots it will automaticly, without any input from me override the current VGA bios and replace it with my original one.

I haven't had the need to test it yet, lucky, I might this weekend, would be nice to know if I'm goint to flash the 9750s BIOS.
post #73 of 83
how do you do an autoflash cd? thats pretty interesting. if you dont mind, could you post a quick walkthroguh?
post #74 of 83
sorry guys didnt mean to insult anyones inteligence. the other option is just flash with out the screen , after youve flashed 20 times it gets pretty easy to memorise it happened to me when i tryed to use a dell based bios, im asumeing they use a diferant eeprom cos my video card really didnt like it.
post #75 of 83
Ofcourse let me test it first, I'll have the chance to do so later this evening, if it works I should see no problem in trying to flash the 9750s 7800 BIOS.
post #76 of 83
that would be great silent. you could help everyone else out.
post #77 of 83
I'll test it tonight and if it works I'll post a little guide on how to make it a little later.

oki doki good luck mate

Then we just need a 9750s VGA bios.

How to make an emergency flash disk.

You need a floppy drive.
And an internet connection.

First I downloaded NiBiTor and NvFlash.

Using NiBiTor I read the cards bios and saved the unmodded version as backup.rom.

Then I opened up notepad and typed in nvflash -4 -5 -6 -A -y backup.rom then saved the file as "Autoexec.bat" when you put this on the boot disk it will automatically be run no matter what. Make sure that it's saved as .bat and not as .txt.

Now, make a MS-DOS boot disk from your floppy drive. Then move the two nvflash files over to the floppy disk together with the backup.rom file and the Autoexec.bat, it will ask if you wish to overwrite and you do.

I then chose to burn a bootable cd using Nero 6, you don't have to do this your floppy will work just as well.

Note: Your system has to be set to boot from either floppy or the cd drive, depending on what you choose to use. It will automatically flash your VGA BIOS whether you like it or not. I also had to press y to confirm my flash, not the biggest problem even when you cannot see anything, however the -A entry should fix this, although I'm not sure.

NvFlash
NiBiTor
