evga Nvidia Geforce 6800GT overclocking results?

[dejacky]

My max seems to be 435mhz core & 1180mhz memory. Is this good?

That's a fair bit better than the 6800 Ultra's stock core/mem speeds, so yeah, that's very good.

I've been trying to overclock my own eVGA 6800 GT (now w/ Arctic Cooling NV Silencer 5) but had much worse luck. It has issues, even at a mere 376/1000 - 3dmark03 stutters, and I get worse benchmark results in Aquamark3. Temperatures are okay...guess I just have a GPU that doesn't want to overclock very high. Hey, it happens.

Got mine at 450core and 1185 memory could do a little more but shows artifacts in games

holy "f" mine maxes out at 405/1100
ive thought about getting an NV5...what are your temps like dgevert? could that be limiting your oc?
EDIT: 49C idle, 78C load

410/1080 here with stock cooling. Temps are 57 idle 76 load.

Have u tried increasing the core voltage of the GPU?

I tried that, caused my computer to be unstable and freeze..so I just left it at the stock voltage.

I can't get mine running over 416/1.12!!!!

Were do you raise the GPU's Core Voltage??

U flash bios to raise volts and if you need more yolts again u can pencil mod card or wire it, im on ULTRA ita 1,43v and bios can take to 1,5v, i get 460/1220 totally 3d mark 2005 stable no artifacts but i can run 470+ 1220+ in games and looks ok but white flakes immed in 3 d mark 2005, i prob could flash bios to get it stable but i am waiting to see outcome on pvp so i need keep defaults no mods, temps are never above 52C load in rom temp 21-23C. Chaintech 6800U stock 425/1100

thats not air though; but nice OC. search the video forums for "thugsrook gtu"
he modded a 6800GT bios (the GT bios improves performance over the Ultra bios, it has tighter ram timings) with 1.4 vcore. you can also do another vcore mod to 1.5v if you want
