Just curious to see how many of you guys are clocked at 5 ghz stable and with which cpu.
I've done a 1hr run no errors. However I had to stop it due to heating issues, as is with the hot and humid climate here in Singapore.
WOW! I knew there were some good chips out there, but 5.6 ghz? And on a pre-built system at that. That's unreal. And only 55c on Prime95? Still got room, it won't throttle until 70's.That thing must be blazing fast. That's real interesting though because up until now I was thinking that the FX-8350 were the best binned. Just goes to show there are good chips out there regardless of model number. You have some lucky friends. I hope I get that lucky on mine. Also makes me wonder if those new FX-9370 and 9590 are all binned like that one.Originally Posted by azanimefan
not my cpu, but my buddy called me after he got his prebuilt fx6300 system, so i came over and helped him overclock. He paid too much for the system but it had a solid mb (ga-990a-ud5) an alright psu (xfx-600W) and a corsair h80i. so i figured we'd see how good his fx was and we started out just increasing the multiplier and loading into windows.
4.5, 4.6, 4.7 i was a little weirded out, no vcore bump yet, so we ran prime95... passed with flying colors on stock voltage at 4.7ghz... at that point i looked at him and said "we gotta go for it, you just won the lottery" so we strapped in and enjoyed the ride. it started to need vcore to load into windows at 5.2ghz, we hit a prime stable overclock at 5.6ghz and i think it was 1.4625 (?) vcore... ended up bowing out at that point as we could get it to load into windows up to 5.8, but we couldn't get it stable there... and at 5.7 we needed something stupid like 1.55vcore, and the temps were nuts
so... a day to day 5.6ghz, 1.4625V vcore with a 55C prime95 temp (not sure on that temp, the cpu doesn't report the temps right, going on a best guess from the socket temp reported by the mb) on a corsair h80i with a ga-990fxa-ud5 mb. About as good an fx 6300 as i've seen. (a friend of a friend of mine has an 8320 he got to 5.5ghz stable on air, probably could get it further on a custom water loop, i know he could get it to load into windows at 5.7)
but yeah... even not having an fx or even working with many (grand total of 3) i could tell that chip was special. Great overclocking little monster. I don't know if it was pre-binned by fry's or not. i don't think they do that, so he might have just won the lottery with it. i've been meaning to look into if fry's bins their chips they use in their custom systems ever since i saw that little baby. Cause it's a one in a hundred... maybe a one in a thousand.
we're guessing on the temps... as i said, the chip doesn't report it's temps right (30C all the time, no change). At 5.7 it took too much vcore to try to stabilize for prime... and temps went through the roof on the socket... we pulled the plug on prime after 1 pass, when the socket temp was around 67C and it was still rising. but yeah.. it just sorta hit its wall at 5.6, but still that was a crazy ride. first time i ever personally hand my hands on a pc which broke 5ghz in front of my eyes.Originally Posted by computerparts

What C.P.U. cooler, case, and motherboard do you have to keep your eight core Zambezi stable at 5GHz?
If AVX in IBT was actually working you should be getting around 100Gflops not 45-47. Just sayinOriginally Posted by neurotix
I can run mine at 5ghz at 1.575v and even fold on it.
It will fail Prime95 on some cores in the 2nd test and gets way too hot. It also fails IBT eventually.
However, I ran it that way for about a month and it was totally usable, I could bench with it, I could game on it, do just about anything on it really and the temps stayed below 50C most of the time.
Completely stable? No. Usable? Yes. Sometimes I'd leave it sit overnight and wake up to a frozen mouse cursor. Once or twice in a months time it froze on me completely during gaming. But big deal, I'd just power the machine off then on again and it'd be good to go.
I decided I'd just leave it at 4.7ghz, because at 5ghz I only gain about 2 GFLOPS in Intelburntest-AVX, 47 instead of 45. It didn't improve my scores in 3dmark very much. And running that much voltage through it is going to make it degrade over time. It's the classic balance between more power vs stability, and to me, 4.7ghz is plenty fast, and much more stable.
I'd love to get a custom loop and run it 5ghz daily stable, but the last I tried to push it it needed 1.6v and still wasn't stable. My machine also shut off completely in the middle of Prime.
