If we do this mod does it require a 130 W power brick?

Perhaps. The obstensible purpose of this thread is discern why the GTX bios scores differently than the native bios in a 7900GS card. But you certainly can't draw that conclusion without a much more detailed analysis. Scores are clearly not dependent only on clock frequency. A score can move >50% without changing clocks at all due to driver choices, background processes & a roster of other factors. I clearly stated that I was adjusting parameters such as δ, tRAS, tRP, etc, which all have significant impacts on the ultimate score. If you post detailed information on your scores & perhaps we can draw some meaningful comparisons.

Which is more important for overclocking on this card, the core or the memory? If the memory is more important, should people leave the core low at first, find the max memory overclock, leave the memory overclocked, and then find the max core overclock? If the core is more important, they would do the opposite.

This card is core limited. As you described, it would be prudent to start with a low memory clock until you get a sense of where the core tops out. Then reduce the vertex shader δ to see if you have really reached core max or if the shader is the holding the core per se back. Then memory clock & lastly latencies. Don't forget to include some safety margin before settling on your final clock or your card will be instable when ambient conditions vary.

A bit out of a novice's league. A slightly more in depth guide is needed for the vertex shader and latency settings. What program to use and how to change them would be appreciated. Say one finds the max core clock with low memory clock. Next, you say to reduce vertex shader (insert funky symbol). First, show how to do this. Next, what indicates whether the shader is holding back the core? What do you do next if the shader is holding back the core? What do you do next if the shader isn't holding back the core? After this, you find your max mem clock. Fine, not too hard. Lastly, you check your latencies. Please inform us novices how to change/check latencies as well. You also state to include a safety margin. How exactly is that done? Do you simply back off all of your overclocks, vertex shader settings, and latencies a bit, or just one of them to be safe? I am sure everyone that is not a pro at this appreciates any help you can give them. Attaching screenshots as our truck driving friend does is always appreciated by the novice!

Okay, okay, I'll explain all of the above. But I'm really busy at work this week, so either check back in a few days for explanations. Or everything is already accessible via Google, if you don't want to wait. All of the adjustments can be made with NiBiTor. δ = delta, which is an offset for the shader module, if you want to give it a different clock than the core. As I said above, more details when I can spare 45 minutes to write a more detailed description

would someone be willing to create a new iso image for me? i've gone through a couple cds and cant get my computer to boot off the iso image on the cd. i need some additional roms placed on the cd, so if someone would please pm me, i only need a couple more. thanks

ok after another hour of gamming i have to say that

Before with 2500m bios after 1h of gamming

Temp with windows fans 94º
Temp with i8kfangui fans 85º

Now with 7900gtx bios after 1 hour of gamming

temp with windows fans 90º
temp with i8kfangui 81º...

If i put screen vertical sync on i get about 30fps on need for speed which is a 5-10 boost... enough to play hehe...

Remember that changing latencies wan not part of this thread, or was not meant to be, so i havent added that information, first of all becuase i havent succesfully changed them without major crashes! lol As soon as someone adds that information i will gadly add it to the main post, i will try it myself and see jow it goes. A safty margin means going about 5-25mhz back to ensure stability on extreme conditions. That will reduce you about 1FPS but is worth it. Shader means memory, Normaly with this bios mod you may raise it above 700 but your GPU max clock will remain the same, just more stable.

We are not suposed to change latencies and allmost noone is doing it, so that information is not being posted. But in the end everyone can compare only thier scores to their own, using different settings, and configurations and clocks. I dont advice it for noobs, not until some sort of guide is out. Finally i know that everyone here want to have the best posible score posted even if not even them are going to use that configuration (I know its not ethical that is why i posted my day to day used configuration) so every one is cheating in some way, but then if everyone is doing so, then all scores are comparable (except for mine). lol

What kinf of rooms would you need? I could add them on the next ISO version. Updates done!

t2600/2gig 533/wuxga/80 gig 7200/single pipe/xg mobileforce driver 91.28/90w/615/850/1.24v/GTX bios

Update:
moved slider to high performance instead of high quality, netted almost 100 points more

Ok.. I am attempting to flash my 7900GS to the GTX bios. I successfully got the image onto my thumb drive and am in the command prompt and can see all of the .rom files. I wish to flash to the 615C850.rom, so I input "nvflash -4 -5 -6 615C850.rom" and hit enter. This is what comes up:

Checking for matches betwee display adapter(s) and image(s).

Adapter: GeForce Go 7900 GS (bunch of stuff)
WARNING: Firmware image PCI Device ID (10DE.0299) does not match adapter PCI Device ID (10DE.0298).
WARNING: Firmware image Board ID (7107) does not match adapter Board ID (7106).

Press 'y' to confirm override of PCI device ID (this is usually needed only for special circumstances)



Is this normal? I don't just want to hit 'y' and hope I got it right, if you know what I mean!!!

Also, will this .rom up the voltage to the 1.24 automatically??

Thanks guys!! Nice job on this so far!

Yes because your changing the cards TAG id to a GTX from a GS. And yes this will up th evoltage to the native 1.24 that the GTX uses.

Are you talking about NFS Carbon? If yes, then... which resolution and settings are you using? With 1600x1200 + max settings (no AA and no vertical sync), I don't recall getting more than 20 fps.

Has anybody got a spare go7900GS ?
My BIOS flash has gone belly up and I have a 'dead duck'

Anybody with a go7900 GS lying around after a dual heat pipe upgrade etc or knows of somewhere where to get one, can they please PM me.

I want to get back in the game again
All my efforts to undo the bad flash have been fruitless.

Glad to negociate on a price for it.

Hmmm but try again, maybe your problem is getting trew the initial setups, hitting F12 low arrow to boot from CD then enter, low arrow to select max memory, enter, enter again, then nvflash again.

If it does not work try calling dell and tell them that your laptop just died and if you are still under warranty they may repair the "random dead laptop" lol, just dont tell them what you did.

Wow. Which flash was that pieter, was it this ISO? I was going to flash quite soon, but reading your statement has made me second guess the safety of something like this. I understand the risks, but I wasn't aware of anyone killing their card yet. Care to share exactly what happened?
