Unlocked Nvidia-Dell Video BIOS! Overclock your 17inch notebook Videocards! - Page 20

do you think 655 on the memory is to high with 1 volt flash. (my optimal freqvens is 455/655) people talking about clocks way higher, booth on core and memory, it should be fine, or ? use 455/655 right now.

Try to increase memory and core slowly with lots of testing untill you reach a point were you get artifacts.
Then lower the clocks 15 to 20 mhz and you should be fine.

Every card has its own limit. You just have to try.

i cant go higher, 455/655 is the highest clock with 1 volt on my go7900gs. im really pleased with the power and the temp. think i stop there.

Hey, that's all that matters =) If you're happy then that's the best part. I monitor my temperatures with rivatuner, and I'll tell you that if you set the recordings at about 5 sec intervals you will see temperatures rise and fall. The power brick might get more hot depending on how much CPU, memory, hard drive, and other component usage there might be, but here I'm just guessing on this curiosity. Anyway, enjoy your laptop!

I wish I could install a 79xx on my inspiron 9300... :B

i use rivatuner, (love that program), BUT how do you monitor the temp wiyh it ?

I have a question about the unlocked BIOSes. Is there an advantage to using the GTX BIOS on the GS as opposed to using the GS BIOS? I know when the first GSes were flashed to GTX it was so they could reach higher voltages and higher memory clocks, but it seems that you can reach the same with the memory-optimized GS BIOS, is this correct?

There is no difference between the stock unlocked 7900 GTX bios and the unlocked, memory-optimized overvolted 7900 GS bios. The only difference b/w the 2 bioses are the labels: 7900 GS and 7900 GTX.

On another note, on page 11 of this thread, Yolda posted a PM from Centi regarding adjusting the timings and delta values on the card through NiBitor. Has anyone tried this themselves yet? Centi mentioned that he could hit approximately 9000 3dmark2k5 on just stock 1v by just tuning those settings...Perhaps this could solve a lot of the heat issues around here.

There is a customize button in the main window, if you click it one of the options pops up a hardware monitor. It is not the same customize button that you use to overclock.

I tried the delta offset and got ~8550 3dmark05@1v. This is a great way to improve performance my results:
shader/geometry/mem/result
540/640/550/CRASH
530/630/550/stable
520/620/550/stable (I use this one)
510/610/550/stable
500/600/550/stable
anything less=stable

my previous high score with 3dmark05@1v was ~7980
I now get 8500 easily.

This is a great alternative to increasing the voltage for those who don't like their card running @ 90 c

Awesome, thanks for the update Justageek95, I will try out some of those delta settings.

did you use gtx flash to your gs-card ????????????????????

have the same like you, but use 455/655 instead.

Justageek95:
Surely you mean geometry = 420, shader = 520, and memory = 550?
Geometric Delta Clock should be lowered (you put in a value of 156 to offset delta by 100 mhz right?) in order to achieve a higher shader and ROP clock right?
It would be hard to imagine that you could run 620 core clock speed by just off-setting delta by 100 mhz...

I'm currently testing out clockspeeds with a 100mhz offset to delta (-100 mhz). For some reason, I can't get my core any higher without getting artifacts from ATiTool (even with compatibility mode on), and when I try to set my core manually with Nvidia Control panel, it always tells me I've failed. When show the 3d window and then activate the artifact scanner however, it gives me no artifacts...could I be doing something wrong here?
My max core was 485 and memory was 710 when I was testing out my maximum clock speeds @ 1v without the delta offset. I'm currently using the 790GSUON rom from JuanLu and running on 84.63 drivers...

790GTXUO.ROM for 7900 GS Rocks! 3DMark05 10057 Baby!

Just wanted to share my findings with this Unlocked BIOS and all I can say is INSANE!!!!!

With the 7900 GSX BIOSES, my 7900 GS card could only hit v540c800 before starting to crash. But with the Unlocked Memory Optimized BIOS 790GTXUO.ROM from juanlu206, I maxed out the Nvidia Control Panel settings at 640/800 and I think my card can still go higher.

I've only had a chance to compare the GSX BIOSES vs the Unlocked Memory Optimized 790GTXUO.ROM, but in every instance, the 790GTXUO.ROM came out ahead.

Thanks juanlu206, you are da man!!!

Everyone else, party on!!!!!!

I am using an external Dvd/Cd now after adding a second hdd. How can I boot the iso cd with the external? I have tired and it will just boot the hdd. I've made sure the bios will boot usb and cd, but still no joy?

Help!

Steve

the easy way is to move the iso flash to a USB memory.

then boot .

I did set the delta offset to +100. I also found that software overclocking was difficult with the offset. I just decided to flash a stock gs bios with modified clocks.

Justageek95:
Hmm, thats interesting, you increased delta (for a higher geometric clock) instead of decreasing it in return for higher core clock speeds.
How is your stability with an extra 100 mhz on geometric?
Did you try doing the opposite and decreasing your geometric?
