[Official] The Sandy Stable Club **Guides, Voltages, Temps & BIOS Templates** Inc SPREADSHEET - Page 3

Almost 2 days...still have ss of it somewhere. Ill find it and post it tomorrow when I get on my pc(on phone right now)

Just curious man, how did you increase your fan speeds to max? I'm struggling with the same issue, I don't think my fans are running full speed so it's hard to get to 4.8ghz+.

We have the same Bios.

well if it restarted at 1.472 after 8+ hours, i would say back down the overclock or up the v. entirely up to you but if it restarted i wouldnt consider it stable.

8 hour blend test is fine for 24/7. I found that an 8 hour blend test failed the new AVX Linpack for SP1 within 5 minutes. Took a bit of tweaking to get AVX Linpack stable. Then again the 8 hour prime blend saw about a month and a half of daily use without BSOD so I'm not saying blend is unreliable, just saying it's not the best per se.

Depending how long you want to keep your chip, it may not be worth going above 1.48v to 1.49v although your cooling is amazing. If your board allows you to do this, drop CPU PLL below 1.7v, I actually tweaked it down to 1.65v to pass AVX Linpack and that seemed to have helped me. I think you can set the pwm frequency on the Asus boards up to 350hz, doing that may help you achieve stability at 5.1 w/ 1.464v as it lowers the ripple going into the cores. I'm just trying to suggest things that don't involve increasing vcore but ultimately vcore is king.

You must also consider your chip would likely be able to do 5 Ghz with much lower volts than most of us, but 5.1 is worth trying for tho.

Prime95 blend takes ages to be honest, AVX Linpack for sp1, although the temps and current draw on the cpu is much higher than blend, is a very quick efficient stability test. While prime95 blend might take 7 hours to pop up a BSOD, that OC would fail AVX Linpack in under 10 minutes, allowing you to spend more time tweaking and less time waiting for 8 hour blend runs to fail. If you try AVX Linpack however, it would be wise to lower your ambients, just to give you an idea cpu watts during blend sit at about 118w, for AVX Linpack I've seen 152watts so expect some serious heat. The only way my air cooling can handle that is sub zero ambients lol. I should go for WC but I gotta save 4000$ for tuition.

You have a very nice chip there.

My H50 keeps my 2500k @ 58C load @ 4.7 Ghz / 1.33 vcore

Rasa 360 comes in today

No one really knows how much volts these chips can handle, people will tell you different things. I've had no issues or degrading pumping 1.45v - 1.46v 24/7 for 2 months but my cooling is the bottleneck unfortunately so I have not had a chance to go any higher on the core voltage. My chip does 74c after 8 hours of blend, IMO you have nothing to worry about in terms of temps, stop trying to tweak it haha.
