7800 GT Artifact Issue

[vikingblade]

Ive been told that the only 7800gt's with the artifact problem was the evga's due to the geometric clock. this is supposed to have been fixed by a bios flash.

I was wondering two things..

If anyone is experiencing artifacts with a non-evga card?

If you had an evga card with artifacts, and you flashed the bios... did it always fix?

its possible other 7800 GT's get artifacts if the cards cant handle the clock speeds.

EVGA 7800 GT's are the ONLY 7800 GT's that have the geometric clock set to 40mhz, other 7800 GT's have it set to 0. The geometric clock adds 40mhz to the GPU running 3D apps (making the GPU 486mhz). Some EVGA 7800 GT's can handle the GPU at 486mhz, but some cant. If you do get artifacts, flashing is a good idea.

What the new BIOS does is remove the 40mhz geometric clock (so it runs at 445 in 3D apps instead of 486). EVGA also made the 3D and 2D clocks the same making it more stable. The old BIOS had the 2D clock set to 275mhz and the 3D clock at 445/486. I'm guessing EVGA is starting to put the new BIOS in their new cards, but old stock will have the old BIOS.

The new BIOS SHOULD fix the artifact problems, but if your card cant even handle 445mhz, you will still get artifacts, but this probably wont happen.

thanks man. great info. are you now running stable/artifact free, at 445 with the new bios?

 

[rahzel]

yup, i can run at 470mhz now.

so if i buy a evga 7800gt co and it artifacts on me, what do i do, go to evga and look for the newest bios...then flash to new one. dunno how to flash.... is it simple?

Very simple. Go to evga's site. Hit up their forums. Enter the 7 series forum. Sticky at the top explaining the new bios.

They have a self extracting image that will write itself to a floppy and you boot from that. It'll take care of itself from there.

My 7800GT is much happier now that random spikes don't shoot out at me in BF2.

EVGA_Engineer posted BIOS updates for both the regular 7800 GT and the CO version. Just click the link, have your serial number in hand (it will ask for your serial number. also, the flash instructions are on this page), download the BIOS and flash.

does anyone know if the new bios flash for the CO will lower my clock to a regular evga 7800gt or will it still be overclocked faster than the regular model
