What is wrong with my 8800gt?

Drinkyoghurt · Dec 3, 2007

I have the Jetway 8800gt, did the bios softmod.

before the softmod my max clock on the core was 680, after the bios voltmod it was 720, however when I de-linked my shaders and put them to 1782 they worked fine, but if I bumped it up to 18xx it would artifact on me.

I can now do 730 on the core, haven't tried anything above it yet, but does it cause damage to slow down the shaders?

You're fine. I can only get 1728 on the shaders w/o any artifacts.

What do you mean by "slow down the shaders"? What were your stock shader clock? Mine is 1500, so anything more than that is speeding up the shaders.

I mean slow down as in slower then linked speed.

how high can you clock your card then?

I haven't read of many people getting 1800Mhz+ on their shader, especially with stock cooling. Surely a 280mhz overclock is high enough for the card.

At the moment I'm at 720Mhz core, 1780Mhz shader and 1910Mhz memory. This is unvoltmodded, I presume. (It's a BFG card, so I am not sure)

Anything higher than 1780Mhz shader doesn't work for me either. It doesn't cause artifacts though, it just causes a flat out GPU reboot (not system, just the video card)

this is the highest I could score with my card, those numbers don't seem right, I see people with even lower clocks( 700/1000 ) beat me...but they have their e6750 @ 3.6ghz, I only have my e6420 @ 3.6ghz

No it will not hurt the card. The relationship of the core ROP to the core Shader clock is just
a function of where they are set in bios. That can be easily changed by editing the bios and
is done all the time.

clocks are in sig. This is w/ the 1.1v mod as well.

Your score looks fine. I have a quad at 3.6GHz, and get almost exactly 1500 more than you...which is expected.

Yup no issues with running shaders at different clock speed then core here.

740/1828/1000 is the highest I've tried in 3D Mark. 720/1782/950 is typical gaming speed for me without Bios mod. Get a new cooler tomorrow so I'm eager to see what it can do then
