GTX 570 overclocking thread - Page 159

Hey DPH. I think I'm going to try to shoot for 850/2000. Hoping my cards will accept those settings at around 1-1.3 voltages. Found the sync settings box in MSI afterburner and have that checked. Also checked unlock voltage control as that was the only way for me to adjust it. I don't have a custom fan profile set as of yet, but will def do so once temps start getting a bit on the high side. My old 470's use to get HOT so I've played around with the custom fan profiles. These 570's run so much cooler Also have a HAF X with pretty good airflow inside as well. My 570's are EVGA so I'll be a little more at ease knowing EVGA supports OC's. I'm super excited for the VG236HE that should be coming in tomorrow. I know a lot of people say 120hz is a waste, but I really don't believe so. I've played on my friends 120hz monitor and the overall feel is so much smoother granted you have good enough GPU's to sustain the frames. Another reason for the purchase is I absolutely hate screen tearing. Turning VSYNC on does eliminate it, but for a lot of games VSYNC makes the overall feel sluggish for me.

I'm currently downloading 3D Mark Vantage as a bench mark test to see how many frames upping the settings will improve. Realistically I'd be content with 5-10 FPS gain granted I don't have to raise the voltages too much. Do you have any other recommendations for testing stability? I currently only have OC Scanner. Thanks for the reply

So after some fiddling and testing I'm sitting on 1.038 Volts running 850/1700/2000. Do those volts seem a little low to you? I ran OC Scanner for 20 minutes and no artifacts. Ran heaven bench multiple times no crashing or artifacts. file:///F:/FPS-Bench/unigine_20120117_0242.html I keep getting a stupid low minimum FPS. My FPS starts really low when the benchmark first begins, but then it just jumps up. Afterwards never really saw it dip much below 30.

OCCT gave me a crap load of problems. I first tried 4.0 and no matter what, I just could not get the GPU test to run in full screen mode with error reporting enabled. I was able to run it in windows mode without error reporting for about 45 minutes then I stopped it. No artifacting that I could see. Then I downloaded OCCT 3.0 and was able to run that for 30 minutes full screen with error reporting. No errors, but the FPS stayed very low and my GPU usage was very jumpy so don't know if that counts. I tried OCCT on stock settings and had the same issues so it's not the overclock. Did quick a search and two other people had the same problem so it's not just me.

UPDATE
PC froze during Metro 2033. Upped voltage to 1.050. Also download OCCT 4.1 Beta and the GPU test actually worked for it. Ran it for a hour no errors or artifacts. Two videos cards never exceeded 73C. Pretty content at this point, I think if I have anymore game crashes I'll underclock the core clock a bit as I don't want my voltages any higher then it's at now.

Ive been reading through the thread as I have watercooled my 570 I thought i'd push for some pretty high OC's. What I want to know tho is the maximum save voltage for this card? I have the Gainward GTX 570 golden sample goes like hell..... XD. To me it seems that 1.1v is the maximum safe, is this true? (for a 24/7 overclock)

Currently sitting on 900/1800/2075 with 1.088mV which Im quite happy with, was getting it stable at 1075mV in heaven benchmarks but crashed instantly in BF3, so I had to bump it up and presto, currently playing BF3 now

I think I have settled on a similar 1.088v 900/1800/2100. I don't think mine can handle higher voltages and slightly higher clocks from what I have seen.

Well the increase in performance for the increase in voltage from now on isnt worth it imo, card will start to die out quicker from what I know over 1.1v, so keeping it under 1.1 is nice

Agreed. Going from 732/797 to 900 brings BF3 Ultra from ~50fps to 60. I can live with that.

I've settled at a 820/2000 and 1.05v myself. I don't get much better performance, I get more heat and the occasional instability above that. I can do runs with benchmarks, but can't game for hours with 875-900range.

BL I guess. I got a shocking OC'ing core. For a d0 i7 920 it needs 1.38v on the core to hit 3.8ghz... -.- SO im just running it at 3.6 at 1.3v. Gotta say I love liquid cooling as my system is whisper quiet

I was able to push a single card further with less voltage, the second card must be a dog, but I can't run them at different frequencies
