8800GT Overclocking Thread (Official?)

[Matkun]

Any reccomendations for a cheap but effective aftermarket cooler for the 8800 GT? I'm curious if I can get a better OC by getting some more cooling, and the tiny fan on this whines like mad if I push it above 50% duty cycle.

[Freeboy63]

air or water?

For Air, The Artic Cooliing Accelero S1 is cheap and you can stick a 120mm fan on it.

[Freeboy63]

note, lots of water options if so inclines, I am going Danger Den Maze 5, and soon they will add a full sized block, but those are never my preference...

[Matkun]

I'm looking for air.. and yeah, does seem Accelero S1 is cheapest, though I'm getting worried about the ram and the PWM chips on the far right of the card.. Would it cool those sufficiently?

Also looking at Zalman VF1000 and Thermaltake DuOrb, but those seem to be $50 compared to $30 for the S1.

I am not doing the traditional heatsinks, on the memory in favor of blown air from a VERY high volume 80mmZalman RdM8015B

With heatsink on the PWM and the RAM + 120mm fan zip tied on the GPU heatsink, it will give you enough airflow to cool them down

If you are really worry you can buy PCI fans and put them under you card or use a spare fan + chop stick mod.

what can I expect for overclocking on the stock 8800gt @ 600/1800 not sure shader

and about vmods you can use nibitor VID? or have to use physical vmod?

There is a Bios mod that can increase the stock 8800GT Vcore from 1.05 to 1.1V: http://www.xtremesystems.org/forums/...35#post2560835

Works great and can give you between 0 to 50 MHz on the core and the shaders. there is also a Hard Vmod that can increase up to 1.3V if you have good cooling, search in the the Vmod sub-forum.

[ziddey]

I wonder what voltage we can feel comfortable at. I know with the g71, there were models that had 3d mode up to 1.4 or 1.45v, vs the stock 1.2v.

I just ordered the XFX 8800GT Extreme anyone has this card? I'm interested to know how the card clock and what is the default shader clocks.

[Matkun]

Anybody done a stock vs aftermarket OC comparison? Not sure if it's worth it to spend another $40 (20% of the price of the card) to get 1-2% more performance.

Today I put a Thermaltake Duorb on my 8800GT. It works pretty good considering the price of 30€. Load temps dropped like 25 degrees...

Now i want a new motherboard....i need SLI

Hello folks..

See ya!

My first run with my new set-up:

See sig for spec

CPU VCore is set at 1,3V in BIOS (1,256V after droop)

Guys I really need your help here. I experience some crashes in Gears of War in default speed and Crysis if i OC the core a bit. I get blue red and green pixels along with a freeze of the screen, then one new frame is drawn where my pc freezes completely, but the sound continues. It is ofc my brand new asus 8800gt.

I removed the stock heatsink and installed my waterblock, 8 small copper heatsinks on each ram chip and 4 small heatsinks on some mosfets. Theres a 12cm fan blowing towards everything.
The GPU temp in everest and atitool shows ~30 on idle and ~50 on load. Wtf is going on?
I lowered the core and shader clocks and it seemed to be more stable in Gears of war. I have tried reinstalling my waterblock 3 times. It seems to be fitting perfectly.
I noticed the stock heatsink is in contact with many mosfets. I noticed where the white compound was touching the card and added heatsinks there. I think i got the right mosfets. Are there any particular ones i should pay more attention? Could it be the mosfets?
Should I keep the core and shader clocks linked when OCing?
Any help would be appreciated thanks.

Edit: I noticed theres a difference in gpu temp from atitool to everest. Atitool shows 54 on load while everest shows 47

The thing is I never tried the stock core heatsink, I put some glue on the ram heatsinks and it will be a big deal to remove them to put it back

[giorgos th.]

Did you put the glue carefully?
you might have a short circuit there in your mem chips,so you have artifacts.

[nuttah]

Very carefully. The thing is Gears of war makes this happen in 3-5 mins. The other games dont.
I reinstalled the waterblock and now the core temp seems NOT to increase at all when I run atitool - Scan for artifacts!!! Only 1-2 degrees

I have had this card for about a month now and........well have probs
Maybe someone could help
INNO 8800GT wont run 3dmark06 and 05, 03 is OK in XP sp2, XP 64 corp, or vista 64 and 32
all dx up to date also tried with dx supplied with card, no success.
in Xp I get a message
D3DERR_DEVICELOST
IDIRECT3DDEVICE9

Also, card runs damn hot, fan on 100% all the time, case open and a pedestal fan blowing in side (during day), idle is 53-58, in game about 78-84, only take around 10 mins to get hot, all temps at default clock settings, worse if overclocked, best yet is 648/1053

And last of all, in game eg COD4 stalker, crysis, mouse and keyboard go crazy IE the controls, all this has happened since 8800GT installed

All the above were done with clean install and format each time

I assume thats with a hardware mod?

Yep, VR volt mod.

pics of the duo orb ?

[Freeboy63]

well, it is a hot running card, 50 c is not tooo hot though under load, Without seeing , reading of the wc system I hesitate to advise..
My 8800 oem which says Nvidia gforce but made by galaxy oc's on stock runs hot.. but my water sys goes in the next few days.. will post temps.
