8800GT Overclocking Thread (Official?)

**leoftw** · 12-15-2007, 02:41 AM

how good are these scores ?

**Budwise** · 12-15-2007, 11:55 AM

funny how my 3.6Ghz Core 2 Duo ruins my 3dMark06 score so badly. I beat leoftw's SM2 and SM3 scores quite badly although i score over 1200 points lower just cuz its a dual core instead of quad.

**[XC]Atomicpineapple** · 12-16-2007, 02:57 AM

I have a problem. I ran 3DM 06 at leoftw's GFX clocks and got the same scores, but our scores are made in different ways. Im way low on SM2 performance and a bit down on SM3. However I have an extra 1k points on the CPU test (I'm running dual quad core xeons clocked at 3.4GHz) that bring my score up to 14.3k. This seems odd when I'm running an identical card at identical clocks.

So really what I'm asking is are there any settings that can raise my SM2/3 scores. See link below for screenshot.

**Budwise** · 12-16-2007, 12:34 PM

thats why 3dMark06 blows. Its very CPU dependent with its scoring. It sounds like drivers maybe? Do you have the Vista hotfixes installed?

**Paxi** · 12-16-2007, 01:18 PM

I´ll get my EVGA 8800GT SSC tomorrow, but i need to wait for my new res to rebuild my Waterloop (dont cool the GPU for now). Can´t wait to see how it performs, expecting results for the weekend

**TheCarLessDriven** · 12-16-2007, 03:01 PM

im at 730 mhz core now, and 2015 mem (not halved) and 1625 shaders (stock shaders). No pics right now.

8800 GT 720/2044 Q6600@3.8ghz

**LagunaX** · 12-16-2007, 10:06 PM

Hey guys quick question as this topic is spread out over a coupla threads:

Which 8800gt cards are the better overclockers and which are the worst?

Or do they all overclock the same?

Will a cheap PNY 600mhz card hit EVGA SSC 700mhz levels by a bios flash or do I need to go EVGA/XFX/BFG for a better chance of success?

Thanks.

**S1mon-** · 12-17-2007, 12:20 AM

All companies are about the same... It just a hit and miss with these card so just prey to have a good one

Mine is doing just great... My shaders are backing me up a bit...

1775MHz seems to be the max for 24/7 usage... but I can bench at 1860MHz...

Is there any way to raise the voltage a bit on these cards?

**Budwise** · 12-17-2007, 09:24 AM

so far with the stock bios im hitting 750/1810/2000 with my XFX Aplha Dog...

**TheCarLessDriven** · 12-17-2007, 01:04 PM

I wish people wouldn't post halved scores, god thats so annoying, just post the actual freaking Mhz. So damn confusing.

Probably Vista > XP :P I'm @ 3.2GHZ btw if that makes any difference :P

his run is in Vista too if you look at his screenie. Either that or its a transformation pack for Vista icons...

Doesn't look like vista

Whooops I see it is vista "DOH"

**[XC]Atomicpineapple** · 12-18-2007, 05:46 AM

Yup its vista. Though I'd disable Aero to see if that helped things.

**LagunaX** · 12-22-2007, 08:59 PM

Finally got a BFG 8800gt OC 512mb stock 625/1900 off ebay. Picked up a Zalman VF900 Fatal1ty too. Total for everything was $275.

Used NiBiToR v3.6 to modify the original bios to come as close to the MSI 8800GTS 512mb at 730/1800/2000. Tried 1825 for shaders but somehow would let me flash past 1800.

B4 with the stock cooler I could only hit SSC levels stable at temps 52>81 C.
After installing the quiet VF900 Fatal1ty I hit MSI 8800gts OC levels, 40>55 C.

Not too extreme but I'm happy

**david901101** · 12-24-2007, 02:11 PM

703/1728/1000 is max with stock cooler for me

.

I know it's not that bad, but it would be nice to have a good clocking card for once. So now I'm thinking about returning this card to the shop and get another 8800 GT. Hopefully with samsung memory

.

Ordered me a Galaxy 8800GT today for $209 after rebate

Does anyone know if the mounting holes on these are the same the rest of the 8800s?

Good price

They do not match the previous generation 320/640/768mb 8800 series cards.
But all the new G92 8800 series cards have the same mounting holes including the new 8800GTS 512mb. Check out the review of the XFX 8800GTS 512mb on www.hardwarecanucks.com for more info on mounting an HR-03, or Hardocp has a review of several current aftermarket coolers that fit the new 8800GT/GTS

Kinda late in the game but here's my 8800GT-OC.CPU is bottlenecking me as you can see from the final score.

**giorgos th.** · 12-28-2007, 05:20 AM

oh yeah...it`s bottlenecking you badly....

**eva2000** · 12-28-2007, 05:51 AM

Yup these cards will bottleneck ya if ya don't have enough cpu powa!
