Max your power usage and voltage out. You won't burn your card out so don't worry about it.

Windows 7 64-bit, Nvidia Driver 310.90, MSi Afterburner 2.3.0

Gigabyte GTX 670OC 2GB @ 1149 MHz Core Clock, 3005 MHz Memory Clock.

Stabe Overclock @ 1293 MHz Core Clock, 3602 MHz Memory Clock.

Settings Adjustments @ +144 MHz Core Clock, +600 MHz Memory Clock.


Additional Notes:

@ 70 C the Core Clock decreases by 13 MHz to 1280 MHz. Increased fan speed to keep temperatures below that point to solve this.

Can only increment settings by +13 MHz after 105 MHz. Crashes occurred @ + 157 MHz.

Tested several games and MSi Kombuster. No crashes occurred @ +144 MHz.

I think I found my sweet spot. It's stable with heaven also stable with 3DMark11 (dont have network connection yet to send results from 3DMark11). I will test those settings with BF3 and GW2, we will see if it crashed, but for now this is the best results I got as so far with my video card.

PS: Don't pay attention to the CPU temperature, I didn't OC it yet but I will do. I just got a new pc and for now I OCed my GPU card. Time for CPU biggrin.gif

I wanna see if your max Heaven stable works in GW2. For me, I had to back off my mem by 37 and lowered my core from 1280 to 1267 to gain stability in GW2.

what was the max temperature your gpu hit with those OC settings running ur benchmarks?

My GTX 670 with no OC at all wont down clock. Usually they downclock to like 300MHz or something but mine is not doing so. Nothing is running not even a browser. Is this the result of flashing the bios? All I did was unlock it.

Make sure K-boost in EVGA Precision is disabled.

I'm having trouble getting a stable OC on my 670 FTW and was hoping to find some help here. I think I should be able to get A LOT more out of my GPU than it's giving me. Here is a screenshot of Afterburner (was using precisionx but it wouldn't save some of my settings randomly). With the OC shown, I am around 90-95% power usage, but when it crashes it dips to 40% and then peaks to 330%... is that normal? and considering my low power usage and temps (usually around 50-55), why am I not able to get a higher OC...? Thanks in advance.

have you tried maxing both power limit and voltage ? your ss shows you havent...

if you have an h80 modded to it, you need to figure out why your temps are so high. 60* is hot for an h80 on it. im on air and dont hit 62*
