G50VT 9800M GS Overclocking?

well I read this thread before I got my g50vt-x5 and wasnt impressed with the overclocking I personally get 640/1600/955 and I ran 3dmark06 and got 10240 but was at 1280x800 on vista and cpu at 2480, could get higher cpu, but when I got my laptop checked extra it was 1.11 and ran 620/1550/955 and uped it to 1.15 and got barley anything anmore, runs hot at 88C but if anyone knows a way to lower ram clocks for I can overclock my cpu higher please tell me it runs 56C tops after prime95

 

what is more important? the core or the shader speeds?
cause if i higher the core for about 10.. i need to lower the shader.. else i get artificials.

thanks :>

 

shaders, but shaders are every 50mhz like 1500 1550 1600

 

hmm is there smth like this 50mhz step for the core too?
i can get 555-1465

 

no the core works in many little jumps like 4mhz or 10mhz just download rivatuner and montior your clocks,

But anyway I found out how to overclock your cpu farther, i first was get 2.45 with my t7450 and now im getting 2.85, my ram was 460mhz with 2.45 and now 445mhz so i found a program called SPDTool that lets me modify my ram so i went in ther and change it to 400mhz to 333mhz and change the timeing back to 6 so this allowed me to overclock the cpu 400mhz withou running into ram instability

 

Hello there,

Well, I've been trying to flash the BIOS and OC this. But either I'm doing something very wrong or I have extremely bad, bad luck.

You see, if I try to flash the bios all the way to a GTS (600 / 800 / 1500 | core / mem / shaders) @ 1.1V then I get all this display driver crashed but recovered or some other kind of error. I'm using the 185.85 DOX drivers.

So I tried something more modest, as someone here proposed, going to 570/800/1425 @ 1.05V... alas, I get display driver errors. Even at 1.1V.

I was sad, very sad. But then, I got the nVidia Ntools whatchamathingie and began overclocking from the control panel, one step at the time to see what was the problem.

I was able to reach 550/830/1425 @ 1.05V with the control panel. Upping either the core or the shaders would start giving me display driver errors. So then what I did was go and flash the BIOS changing only the voltage to 1.1V, leaving the clock at the stock speed.

With 1.1V, I've been able to reach 580/830/1425. It seems I can't move my shader speed or else I start getting driver errors.

... hum... am I in bad luck? The CPU is a T9400, so I figure there's some extra heat, but I'm not sure that's the problem.

What I haven't tried it to flash the clocks I reached directly to the BIOS and see if it works that way.

Any other ideas, tips or tricks you could share?

Thanks in advance!

 

I'll post my experience with my 9800M GS

Successfully, I was able to reach 640/1600/800 @ 1.05v. Anything further, would give me a display error. Now, Even if I flash the voltage to say 1.11v or 1.15v, I am not able to push it beyond 650/1625/800. I get the usual display error.

Success #1 I am able to push the GPU to 600/1500/800 @ 0.95v with total stability for over 25 minutes with ATiTool + Furmark. I can only say that only few people here are able to reach those close at those voltages. In fact, I haven't heard/seen anyone go below 1v at those clocks. Guess I am a happy 9800m GS camper.


My 2c...


Best Regards, Leonid

 

You lucky bastad Hehehe.

Did you do something else besides just flashing the thing? Put some thermal paste maybe? What driver are you using?

 

I do have 2 1/8" thick & 7/8" squre blocks attached to the lower part of the GPU heatsink. That has nothing to do with the clocks or voltage though. I have 186.81 Nvidia drivers.

 

Which lines did you change in SPDTool? I've been trying to change my memory frequency but no luck. Every time i try it gives me a verify failed error.

Thank you in advance.

 

Sorry for the huge bump, but does anyone have the flashed bios file for the G50vt-X5?

 

Follow steps I and II in this thread to get your own. The link to the rapidshare files might work (it's from a G50vt-x1), but the safest way is to extract and modify your own.

 

I can't get my own. I'm having an issue backing up my own. It says"

"Write of EEPROM image to file failed.

I/O ERROR: Cannot create file: OLDBIOS.ROM"

 

Well that's troublesome. Not having encountered that problem, I'm not sure what to tell you.

My guesses would be: 1. There is something wrong with the format of your flash drive, or something else which somehow prevents it from being written to in certain circumstances. Make sure it is formatted in FAT...
2. You somehow have a locked BIOS. If this is so, I doubt you will be able to write to it if you can't even read from it. I would recommend that you go to the Asus website and grab the latest BIOS for your laptop. It's this one here I believe. Even if this is already the BIOS you're running, try re-installing it anyway.

Finally, I checked, and we are both using the same BIOS, so you should be able to use the modified .ROM files in the rapidshare link I put in my guide.

Good luck!

 

Does the flash drive need to be formatted to FAT to flash my BIOS to the newest version, or is that only for backing it up? Cause I can't format it to FAT. My flash drive is 8 gigabytes, so it says "Volume is too large". Is there any way to do it, or do I need a new flash drive?

Thanks a ton for your help!

UPDATE:

I was able to flash my bios with NEWBIOS.ROM, though NEWESTBIOS.ROM refuses to write.

How do I know which is my voltage? RivaTuner gives me a list of voltages.

UPDATE#2

I was able to get my clocks up to GTS speeds by opening NEWBIOS.ROM in NiBiTor and modifying the clocks and saving as NEWBIOS2.ROM. Any idea why I couldn't copy over NEWESTBIOS, but I could copy NEWBIOS2?

 

Actually, here's the easy answer: download gpu-z

Go to the sensors tab and see the VDDC. You may have to run something like a game to get your card to jump up to the higher voltage setting.

If you have NVidia's performance tools installed, you can overclock with that (and even set it to overclock on startup).

 

Oops, new version of NVidia System tools is out: http://us.download.nvidia.com/Windows/nForce/system_tools/6.06/6.06_nvidia_system_tools.exe

 

Thanks. I figured out how to check after I posted that. Well I'm all set. Running at GTS speeds and voltage. Thanks again for the help.

 

No problem.
