I think my vrm temps were likely hurting me on that too.

All that torture and think it only cost me 50mhz of OC with stock voltage. I just keep it at 1424mhz now a days.

1424Mhz @ what voltages (66) ?

I'm trying to overclock my Gainward 770 2Gb Phantom but having some trouble with the flashing. More precisely, I've flashed it with the Gainward BIOS listed in the first post but my voltage is still locked at max +12mV which is how it was before. My card has Samsung memory and an ASIC score of 92.5%, if that's relevant.

Valley on ExtremeHD gets me an FPS of 49.5 with a +30 GPU and +500 MEM - this doesn't seem that great to me?

Would appreciate any input from you hardcore overclockers!

Cheers!

Hey mister, you're in luck, your Gainward 770 uses the NCP4206 voltage controller so you can unlock your voltage using the AB Volt-Mod. Go HERE to read more about it, it's pretty easy to do, just make sure you have adequate airflow/cooling method to keep your GPU below 85c thumb.gif

Ah nice, I'll give that a go. Thanks!

Also, I noticed the power target was supposed to be able to go up to 150% but mine was still locked at 106%. Is it supposed to be like that?

EDIT: I did the softmod and 1.3v is unlocked, but the voltage hack thing doesn't seem to work. LLC seems to be permanently disabled (it never returns 00 like the thread suggests).

EDIT 2: This is weird. The power limit now shows as 150% after a restart, so I've whacked that up to max. My core clock is +225 (1375) and Memory is now +500 (4006) at 1.3v, it only gets to 82c but then at a point in the Valley benchmark, my FPS cuts in half and stays that way until I restart my machine. Even after my temps return to normal, every time after that I run Valley, my FPS stays halved. Does anyone know what this is? No matter how much I fiddle with settings in AB, nothing fixes the half FPS until I restart :S

EDIT 3: I've watched my stats while it's running the benchmark, and the temps hit 82 and power target hit 145 before it dives back down to conservative power targets (~106). At this point my fans were running at 100% so I'll try reducing the voltage slightly and see if I can get the power target to stay lower.

EDIT 4 (sorry!): Lowered voltage to 1.263 volts, core to +200 and now the power target only gets to 122% and the temp gets to 78 and still it dives down into what I'm dubbing "sensible mode." What gives?

1.33v/1424mhz. When new 1372mhz benching and 1359mhz gaming was max on 1.212 (actual 1.222 when using a meter) but now I think the max on 1.22 is 1320mhz or 1333mhz to give you an idea of the voltage scaling and some degradation. Had it within 2weeks of launch and have done some pretty high voltage runs. Tough card/GPU for sure.

hey guys i own gigabyte gtx 770 2gb and these are my results with heaven 4.0

Stock oc

FPS: 27.6
Score: 695
Min FPS: 7.4
Max FPS: 50.6

1st oc

FPS: 29.7
Score: 747
Min FPS: 17.5
Max FPS: 60.0

2nd oc

FPS: 29.9
Score: 753
Min FPS: 15.6
Max FPS: 60.1

Now the question is should i push it and reach 780 points?

Gpu boost offset: 30
memory clock offset:60
power target 110%

Oced with asus gpu tweak, i dont really like precision nor gigabyte supported tweaker and AB for me is just a pain in the back, i like asus gpu tweak even if i dont own asus gpu it still works. its nvidia afterall

Just ordered an EVGA 2GB GTX 770 ACX SC a couple of days ago, was supposed to arrive today "guaranteed" from Amazon, but sadly it hasn't. Hoping it'll show tomorrow so I can break it in this weekend and possibly overclock it. Should've bought the Dual bios version, but amazon had a pretty decent price on this one and I had to upgrade my power supply as well, so money was a bit tight. Ordered an EVGA supernova NEX750g so I can SLI in a couple of months, unless we are surprised with the high end Maxwell cards within my step-up period and the performance difference justifies upgrading. If not, then the price drop on the 770 will more than likely be what I plan to do. I haven't even experienced one yet, though. I mainly play first person shooters and some Star Wars: The Old Republic, on a 23" 1080p IPS Monitor, but plan on buying either an oc'able 27" PLS 1440p monitor or a 144hz monitor, either of which would definitely require SLI. Hopefully it arrives tomorrow, too anxious upgrading from a GTX 460 SE, the performance should more than double. Looking forward to being part of the owners club. tongue.gif

weird fps drops with heaven happens, i try to test on same offsets and sometimes fps are good, then they go very low. OC is stable, tested in games and no drops like that.
