Please post 7900GT / GTX overclock results

[Zyprex^^]

Delta is a setting in the bios. As far as I know, it can only be changed there.

At 560/1800 I get just under 10K. Around 9800 or so.

I would try a different driver and see how it works out. Look on the orb and find the one all the guys are using that are on the fron page and use that one. Should be 84.21 official driver I think.

Ok, I will try other drivers. But that delta thing, is it dangerous to my graphic-card?

But I don't have an account on the orb, so I can't see what drivers they are using.

[Zyprex^^]

84.21 gave me a lower score. It gave me 8.9k with 580/1830 and X2 3800+ 2.6.

[vocch]

This is my 24/7 settings...quite a nice sore i think

Which drivers are you using vocch, I only get 10696 shown below using 84.21

[vocch]

That is a sad score compared to mine at lower clocks......what drivers...now that would be telling ....nah let us know how they do for you.

MSI NX7900GT 84.26

Edit: Just noticed they are the original drivers for your card.

But I don't have an account on the orb, so I can't see what drivers they are using.

A quick search on the orb of the highest 7900GT scores with FM approved WHQL drivers shows every score on the first page with 84.21 drivers, including mine I went through the first 4 pages and they were all 84.21 drivers. Maybe that is the highest driver that is WHQL and FM approved, I dunno.

If you search for all drivers, 84.21 is still on top. But 84.25 shows up a few times as well.


The delta thing will not hurt your card. Its kinda complicated, and I don't get it all, so I can't explain it that well. But there is more than 1 core clock speed on your card. When you adjust the core clock, the others are automaticly adjusted to match. You can see all these clocks if you use rivatuner with the 7800 cards, of course this doesn't work for the 7900 cards yet.

The geometric delta clock adds a certain speed to one of the clocks. So if you set a 40mhz delta in the bios and set your core clock to 600 with coolbits, your core is actually running at 640mhz, which is 600+40.

What I usually do is set the delta to 0 and overclock the card as far as I can. Then I start adding delta in small increments to see how high I can get it. With my 7900GT it was 724mhz plus 40mhz delta.

Hope that helps, but like I said, I don't fully understand it all myself. Maybe someone else with better understanding can explain it better.

Thank you for taking time to help me But where du I find delta in bios?

[madgravity34]

When you open up the bios in nbitor is is the clock usually 0 - 50 on the gt/gtx's that are right across from core clocks and before the memory clocks.

[Zyprex^^]

Where can I download nBitor? I don't find it in google..:S

mvktech.net is who releases nibitor. You can download the latest version, 2.8a here.

There is also a very usefull guide on mvktech.net that walks you through using the program.

Thanks, but where are my BIOS file that I must open?

Read the guide, it tells you everything you could possibly want to know, and even a bit more.

With cpu@2.830 scored 10845... card same as above

Tried the 84.26 but score was even lower so tried 84.30 and got

Thats more like it....i think i'll give em drivers a go and see what i get

Edit:Here's the results

The BIG 11K acheived with a standard 7900gt1.4v@660/1650+an opty165@2750

Some optimisations

(i did the dumb with teh screen)
Freqs : 710 / 903 MHz @ 1.5V @ chill -10°c

Nice

I cant understand how you get a higher CPU score tham me though, I am @ 2.8GHz with 2GB memory, maybe the loose timings have someting to do with it ??, did you apply the AMD dual core driver etc ?? cheers

Thanks alpha0ne.....the amd driver was a big no no for me tried it once and had to format my system messed it right up....i tried my cpu even @ 2840mhz still could'nt hit 11k....i could have hit 11k easy if i did 1.5v but 1.4 is my limit.....what did it for me was to drop cpu a bit + and used 166 divider instead of 133...which i thought higher cpu clock would have done it.....well i suppose it would if you clocked it high enough....but more v's no thanks....it was ram speed that gave it that little bit of help it needed

[mascaras]

my new score with 1.40vmd , no artifacts yet


Opty 148@2990mhz |XFX 7900GT XT (520/1500) @ 1.40vmod@670/880

[vocch]

3dmark06 same settings as 05 run

[Zyprex^^]

Sorry of-topic, but is there any lower vmod then the 1.4v?

[Shark-357]

Yes there is u can add voltage in 0.5V increasments...
Check it out in xtreme graphics mods section

[Zyprex^^]

I can't find 0.5vmod, only 1.3/1.4/1.5v. But do the stockcooler handle 1.3v?
