No, that's not how it works. Voltage is not the same thing as watts/power, and i'm not a certified electrician so i'll shut up now instead of saying some things that are maybe not entirely correct wink.gif

Just stick with x46 for your own sake, lol.

Download a program called "BlueScreenViewer" in case you weren't able to catch the code....

Perhaps pre 8. Personally I have never had the above do me wrong (so far)

Of course this is relative to running stress tests and overclocking solely. Obviously there are plenty of other reasons and that's further complicated by what you are doing. Still every time I have blued during a stress test and it indicated clock machine it was my vcore or vrin, everytime I got a whea blue screen it was my dram or sa/io/id, and if it froze it was only while I was overclocking uncore and vring took care of it. Bar none. (Obv excluding heat as a culprit)

Was getting in the low 90s at that point anyway, so Im just selling this one and getting another.



The Team 2133s I got are nice. Stable at 2400Mhz 10-12-12 with 1.575V in BIOS (haven't tested less voltage yet). Cant fit all four under my NH-D14, so got to change that.


Oh! Well since asus says it.... (Asus also says don't run prime) tee hee.

Fwiw I found the higher the vcore the larger the gap needed between vcore and vrin (beyond .4)

Also for the guy curious about 2.1 making u nervous, if your on water don't be. These chips are fairly hearty. I don't even pause for thought till north of 2.3. Though I haven't found 2.2 even necessary (Atleast as far as 1.55v I haven't gone past that as degredation worried me and heat was nearing 80 on blend which I'm certain meant over 90 if it were via IBT or small fft)

My 2c

That was me. Firstly that assume 2.1 is the missing link to stability, which it might very well not be. I'll get to testing it later. But anyways...

 

The Asus claims about prime not being recommended has been stripped down and analyzed over and over. There is zero evidence that Prime is dangerous in any way to the CPU, any more than Linpack is anyways. The issue is whether Prime is a good stability test. That I'm not as sure, but it's not useless. My regimine still includes running x264 overnight, and then game all day when I wake. No issues then call it a pass.

It can take the single 1.8V input, split that into multiple 1.8V phases, and then regulate each of them individually to whatever is required. So the input voltage only has to be higher than any of the individual output voltages (plus some amount of overhead), not the combined value. The power it supplies has to be enough for all of them at once, but that's different.

That's exactly what I'm doing. x264 all night, or at least 15-20 passes before moving on to do what I normally do. I don't mind a BSOD or two while gaming, but can you imagine BSODing just by testing voltage while gaming? I'd be too frustrated to even game. XD

I"m currently testing x46 with x40 uncore. at 1.15v uncore I'd passed 2 passes of the more intentensive part of x264 and it seems that just going to 1.16 has made it stable. I'm going to see how high I can get it as long as I can stay under 1.2 on the uncore.

EDIT: Nevermind... I moved the mouse to turn the screens on and then instant BSOD. 1.17 it is.

You're aware that Win 8 BSOD's still give you crash information below the message, right? And that information can be used to determine the culprit....
