8800GT Overclocking Thread (Official?)

[styxnpicks]

not bad, CPU score is kinda blah, but still not shabby 2.0 and 3.0 scores for a stock BFG 8800gt OC

Received my Galaxy 8800GT yesterday. It is a rev3 which has the long rectangular heatsink

However is it a pretty decent clocker.

Keep it @ 736/1836/1100 24/7. Don't know high it will bench yet.

My Score (my 8800Gt is at RMA now ;Both Shader Model scores above 6000 )

A quick stability test on my vGPU&OCP modded 8800GT 512MB @ 1.55v with the OpenGL Fur-benchie:



50% core overclock
58% shader overclock
with only 39% vGPU increase

Aye, 'tis be a good start.

Quick question:

From previous cards, I've always found overclocking the core yields better performance than overclocking the memory. Is this also true of the 8800 series?

[giorgos th.]

especially in these cards with the smallest bus width (256bit..)

[BTK]

yeah +/- 25 MHz on memory is like 0.1 fps decrease in games on these cards
anyways

1 hour ati tool
100% game stable

Q6600 - Watercooled
Asus P5K premium/wifi
Crucial Ballistix Tracer DDR2 PC2-8500 2GB
Galaxy 8800GT-stock cooling 756/1008
Ultra x3 1000W

I got 1 from NCIX with new design :/


First testing today, not too bad for 229$

3dMark 06 - 16031
GPU 756/1008

Got my card a month ago and ive come up with this overclock so far: Core: 700mhz Mem: 1009Mhz, Shader: 1750 Mhz with stock cooling, idle it's 44-47C ( 116 F) and load its approximatly 55-58C, seems like i got a cold, stable card.

which memory give better overclocking qimonda or samsung?.

8800GT bios for better overclocking *test*: http://www.xtremesystems.org/forums/...69#post2528669

8800GT at 800 is xtreme! What is vmodded???? Can u give me some links?

try playing CRYSIS for one hour if it works then card is stable, i've read somewhere GPUs report stable on ATI Tool etc but Crysis crashes easily!

What video driver are you fellas using for XP?
Im using vesion 169.28 an rivatuner 2.06 an Overclocking it in Riva has no effect to reverse effect meaning my 3dm06 scorre will drop if I even OC the cards 60mhz. 2X Evga 8800gt 512 in sli on the 780i with the E8400.
Im not new to graphics overclocking this just has me stumped.
Im trying to improve this 3dm06 score but they are being stubborn.

is it true that you need more than a G92 8800 GTS card to appreciate your 24" or bigger monitor?

looking to partner with:
WinXPPRO SOP2
Abit IP35 PRO
e8400 C2D
4GB Corsair Dominator
Dell 2407FPW-HC
to play:
Ground Branch
COD4
BF2
GRAW1&2

Samsung. No idea about hynix though which my card have, that i havent installed yet.

Hey, I'm a noob at overclocking video cards so I was wondering if you guys could help me out with my MSI 8800GT OC with Zalman VF1050 cooler. I'm pretty stable at 700 core, 1750 shader, 975 ram. My temps get up to around 64C in ATI tool. I had a couple questions:

Are there any disadvantages if you don't link clocks between the core and the shader?

How much of a real-world benefit do you get in overclocking the shaders? I'm guessing this depends on the game and I will just have to bench them, unless someone has done an in-depth analysis already for a few games.

Would I get any benefit from increasing my voltage? I know I'll run hotter but 64C doesn't seem that hot. On the other hand, although 64C doesn't seem that hot I'm pretty sure it's heat buildup that prevents me from overclocking further because after about 20 minutes it goes nuts.

I have some RAM sinks I was thinking of sticking on underneath the VF1050 because teh rams are naked. If I drop my RAM to stock clocks, and this allows me to push my core a little further, I'm assuming that I will be able to push the ram AND the core if I stick the RAM sinks on.

Lastly I doubt I can get the card to go much faster than 700 no matter what I do. Am I going to notice a big real world difference between 710 and 700 or even 690? I know you guys are all about the 3dmark scores but I don't really care, all I care about is playin' games. All of the info I've read on anandtech and hardocp tell me that no, the real world benefit will be next to nil. I should probably just drop to 690 for stability and just leave it alone, I think. All the time I spend tooling around, I could probably just work a few extra hours and buy myself another 8800GT.

my XFX 8800gt 512 uses Hynix Chips instead of Qimonda. is this an upgrade or are hynix just as bad as qimonda chips. i read somewhere that qimonda are rated for 1000mhz and dont last at anything over that for a good period of time.
