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)
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.Originally Posted by munaim1;12778480
hey guys a little update:
so I bumped the vcore up by +0.5 to 1.472 and left prime running last night, well I woke up and found that my pc restarted after 8 hours of prime. sorry I dont have a screenshot but I do have the results.txt if that helps lol.
On top of that I thought maybe I could do something else to help the temps even further. I reseated the block and re applied some ic7 and let it cure a for a couple of hours, guess what it helpedit shed a few degrees of the load temps. I think this time round, that is the best seating I have got with the perfect amount of TIM. Anyways I'm doing another run on prime with the same volts and ambient temp, screenshot with temps will be up soon.
By the way if I bump up the vcore another +0.05 it will go to 1.480, which I'm thinking is a little on the high side, what do you think?
Would you leave at 1.472 with 8+ hours prime blend stable or bump up the vcore +0.05 to 1.480 and get it 12+ blend stable?
EDIT: sorry but I also increased all 6 fans on my rad from the lowest possible setting to about a 1/4(so its still silent), which must have helped with drop in temps.
My H50 keeps my 2500k @ 58C load @ 4.7 Ghz / 1.33 vcoreOriginally Posted by E-Peen;12772155
Same thing I'm wondering. I just got my rig built yesterday, OC'd to 4.5 and I got 70c max recorded temp over 8 hours of Blend.
Some say it's 75c, but I'm not sure.
well it's not on max just a 20% increase on all the fans, sorry I didn't mention that im using a fan controller.Originally Posted by E-Peen;12778574
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 is 1.480 considered high? my temps are slightly better than before.Originally Posted by Blue Destroyer;12778579

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.
At the moment im doing 1.472 which is just over 8 hours blend stable. About the pll and pwn frequency, I will definitely take a look at those. Thanks for the suggestionsOriginally Posted by Scorpion667;12778934
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.
thanks bro. now only thing left to upgrade is ssd and maybe another 460.Originally Posted by Scorpion667;12779270
Oh you're 8 hour blend stable? That's all you need really for 24/7 use, the only way I would see an 8 hour blend test fail is maybe folding for days. Anyway nice OC +1
so far so good, same settings but only difference is that I reseated block and applied new TIM. Just past the 4 hour mark and temps are still looking awesome, hasn't gone above 70cOriginally Posted by Scorpion667;12779538
Yea man best of luck with it!
here's the best time I got on superpi and cinebench. while doing cinebench I oc gpu to 930c/1860s/2100m.Originally Posted by Boyboyd;12772107
Wait a minute. Your batch sounds familiar.
Damn, we're 1 number apart. Probably created from the same sheet (or something).
Run some benchmarks like cinebench and super pi next
I got mine to 5.4 with 1.45v but it was too hot for every day use. I bet you can go higher. See my sig for some validation.
