yeh they are great cards , 450Mhz stok cloks to 570mhz its realy good and i also agree that they only dont go further cause they want more voltage

yeh but CO versions its not always = will get more OC than others .They come with higher cloks default than others versions but that dont means that will OC more
look at the example of XFX 7900GT XXX edition that come with more cloks than XFX 7900Gt Extreme Edition and get same OC , only diference is that comes with high cloks default .
i think + 120Mhz OC core with stokcooler and stok bios its good

The NVXP-3 will fit the 7900 GT and 7900 GTX out-of-the-box without any problems. My two 7900 GTX are already running with two NVXP-3. :)Quote:

Have anyone tryed some stock clocked cards and see how they perform?
My XFX Extreme (560mhz) is in the mail already. Cant wait to see what it can do with stock heatsink.
If anybody here actually hit anywhere close to 650Mhz on 7900GT with stock HS, I would be really really shocked. (EDIT: and stock voltage ofcourse)Quote:

How many of you are running Athlon64@3Ghz wtih 1.4V.. how many with 1.2V? 0.2V is HUGE.
2. Thus, about 40% more power due to higher clocks and 40% more due to extra voltage (about double combined - I posted more accurate numbers somewhere) -> thats what the heatpipe cooler for GTX is for.
Congrats to the guy who got 615Mhz.. amazing clocks for so little voltage.. just need to wait for nBitor (or voltmod)
thats what i said , that +120Mhz in the core than the default cloks (450Mhz) its already very good for this cards with default voltage ;)
BTW: who get 615Mhz in 7900GT ??? and with stokcooler and stokvoltage??? didnt saw yet
I went from 500/1500 to 553/1590 as detected by coolbits. EVGA CO cost me $300 shipped to my door from zipzoomfly.com. I will mess around with it later. I am making great progress getting my 146 0604 cab2e epaw that I got earlier. So far I am up to 2.85ghz on stock volts.
in coolbites in Find optimal frekuncies i get 550/815 with stokcooler , and Max core that it past in coolbites its 570Mhz.
next week i will buy a waterblok to the card and see if can get more than 570Mhz
I got an MCW60 and copper ramsinks for mine. I just need some bios that will add voltage and definitely work.
We all, don't you think ;)Quote:

Will a regular small saw be fine for cutting the NV Silencer 5 to fit the 7900GT, or would you use something else?
Maybe you can heat up a sharp knife and slice trough it like butter.Quote:

I post this because i have modded an NV5 once and I noticed it is really tuff plastic. Didn't try the hot knife method though, it's just a suggestion. Else you could try a normal small saw, like a saw for iron or something.
That should not be a trouble ;)Quote:

This is stock voltage ( 2.03v mem) and a hardware mod with a 50K ohm trimmer for the gpu
cpu 3015 Mhz @1.6v Opteron 170 0550 UPMW 434
gpu 600 Mhz @ 1.275v 3D, 1.265v 2d
mem 1790 2.03v
3DMARK06 9560

3DMARK05 15547
Very very impressive score!
would you be able to take pics of the hardmod?
Thanks here is a pic of one of the cards. I wish I could send more volts to them, but they won't take it at this point.
Thanks for the pic!
Did some nice work there :)
prolly gonna need some pretty cold water to get them to like more volts and go higher. Keep up the good work, your flying through a fast pace haha.

higher than 1.275v 3d for gpu? that doesn't seem like much of an increase at all. they load temp in these runs were 24-28 c for both cards, which is fairly low. why can' th these cards take 1.400 gpu voltage or at least 1.300?
oh wow I read that totally wrong. :-S Thought the volts were high lol. Odd that they are not responding at all to the higher volts. Perhaps there is some sort of OVP???
1:30Am here....brain is dead.
evga 7900gt superclocks
550/1580 stock
bench run at 550/1800
cards game at 580/1820 with stock cooling.
cant publish 7900 scores in the orb yet, hence no link. but only 6 or 7 scores higherthatn mine @ 2850mhz, half were x1900xtx crossfire the other half 7800gtx 512 sli. highest score was around 9600. my score with 7800gt sli was 7200, so i got an 1800 point increase for a 25% performance bump, well worth the $160 the 2 cards cost after selling the 2 7800gt's. i had.
