impressed

So here we are .

The Card,

Stok Runs 7900gs@ 450-660[All test without LOD or something else tweak except maximum performance enabled from nv control panel ]

3dmark 01



3dmark 03



3dmark 05

Next step @ setting randomly 535-700

3dmark 01 , 535-700



3dmark 03 535-700



3dmark 05 535-700

Then i switch to WaterCool [watercool setup , eheim1250 , NeXXos xtreme240 , cpu block silverprop Cyclone , Vga block Asetek Dyo ]

I cover the smd's around the core to protect it from contacts with waterblock


The Card attached



Card temps with water [i had applied 2 mutch ceramiq i reapllied and idle temps now are 40-41c]



And the Cake.... First boot --> autodetect optimal Frequencies from Nv Cpanel :holyBatman:

Still Searching 4 the core&mem limits

[Okda]

why did u cover the smd so it won't touch the water block ???

and very nice results

and very nice results

To avoid the Card destroying ?

Thnx . I will run later higher freqs and some tweaks .

[Okda]

maybe i am not that smart but i can't figure out how it can destory the card

about the 7900GS, are u still able to get higher freq !!!!!!!!!

[chron]

yea pretty sweet. With my X1800GTO oc'd and unlocked at 16p 700/700 and my e6400 at 3.2GHz I score 11230 in 3dmark05 but only 5400 in 3dmark06. I wonder if the extra video ram bandwidth is what pushes you 1000 points above me in 06

[Athens[2004]]

SaFrOuT@ Τhe distance between smd' and waterblock is very low , and the waterblock is a bit small so i taped around the core to avoid the block contact with the smd's [on a simple block mevement eg ]

@chron I dont know if mem's do the job only couse those two card's [x1800xl-7900gs] are totaly different core-pcb ect ect. [btw the 7900gs rams are hynix 1.4ns]



My excellent English owns day by day

[Okda]

thanks for ur explanation and sorry for asking a lot

hope to see more O/Cing results

when u where at

Next step @ setting randomly 535-700

did you suffer from heat problems at that frequancy? and how hot did it get with the stock cooler?

[guess2098]

nice man!!!
mine still using stock cooling at 610/800 24/7

Nice overclock!
To my surprise a 7300GT SLi setup is on par /slighlty faster than a 7900GS.
At least for benchmarking. Might be different with games, especially those that arent SLi optimised.

[higgins]

whow.. thats some crazy clocks man. no voltmod? you beat my 05 score by 1000 points. a great deal is thanks to that allendale but still.. impressive

Hmm, not convinced.

My DX9 GT4 in 03 was 189fps with highly overclocked 7300GT but top score with 7900GS was 207fps with stock as far as I can tell. True the total score is about the same but we're running volt mods and bench specific values. 5 quads should beat 2 quads after all ....

I didnt look at specific numbers.
With untouched cards I got 15x fps in Aquamark at 3500Mhz.
3D Marks are better with the 7900GS, considering he is using a Allendale.
But I am quite impressed by the 7300GT setup, I thought the gap would be much bigger.
Keep in mind that he is watercooling his card. With the stock cooler scores are lower than what I got running at stock coolers. But again, its Allendale vs. Conroe, so it aint comparable.

Nonetheless the 7900Gs is a damn nice bang for the buck card and 2 of those cards are really,really fast for their money.

ataky@ I tested with stock cool , ~30minutes No heat problem at all.

guess2098 @ Thnx Maybe we can married eatch other card 2 run some sli :p

higgins@ No volt mod as i said , next step is some tweaks-pencil mods

[ataky]

thanx, 7900gs ordered
club3d, lets see what we can get out of that, no money for buying a vf900 yet

[su27upgrade]

Conroe E6700 - LOD +3 - no mod's.

I have also score with single moded card : >61k

[mundi]

Can you post detail picture of back side PCB, place about R508-511,
its place in 7900GT which can mod by conductive link,
what I little see this 7900GS have same

[DEVIL K-ce]

Bad quality foto - sory

This is mod for 1.4V. With my card mod to more V ( 1.5, 1.55, 1.7V ) is not working.

Vmem mod --> 7900GT pencil trick
