You're making the argument that Haswell is hotter because it is 22nm?

22nm IB-E runs cooler at the same voltage than 32nm SB-E though

Not to mention I believe that there's lesser power usage on haswell when overclocked, and the real issue is heat dissipation, once again relating to the lack of soldering on the chips.

Haswell's not more efficient than ivy at load and has the ivr, but the difference is simply silly

I was testing another overclock, and then suddenly my PC BSOD'ed. I checked what the cause was and WinDBG says the cause was ntkrnlmp.exe. I found another thread about this but it was a bit outdated. Other times it says that the BSOD was caused by GenuineIntel, which probably is the CPU overclock. Anyone knowing what ntkrnlmp.exe is and how to repair/remove it?

Also, overnight I ran a X264 run with a higher overclock on core 1 (which is usefull because of AC4's ****ty port). Core 1 ran on a 48 multiplier, the other 3 cores on a 47 multiplier.
I did not find HWINFO being capable of showing the individual clock speeds per core, but Asus AI suite and CPU-Z (under multiplier) say 48.
1.38VID, 1.408Vcore, 2.15 VCCIN, 34x cache ratio, 2400Mhz RAM C10.
Can I be charted? Here your form:

CPU Model: 4670k
Core Multiplier: 48 on first core, other three 47.
CPU VID: 1.38
Vcore: 1.408
Uncore Multiplier: 34
Uncore Voltage: stock
Cooling Solution: Dark Rock Pro 2
Stability Test: X264, overnight. Ran about 46 times.
Batch Number: L310C195
Ram Speed: 2400Mhz CAS 10
Input Voltage: 2.15
Motherboard: Asus Maximus Vi Hero

I could probably get the voltages a bit lower, but I will do that another time when I'm bored. Temps aren't a problem yet so I don't see a reason to do it now.

Use bluescreenview and say the error code (like 0x00000124, 0x00000101) instead of file that caused crash

Honestly i'd just stay with 1600MHz, I'm only at 2000MHz because my ram is fantastic! Unless you are going to be running servers and running virtual machines you don't really need much higher. The performance benefit you will get is from overclocking. It's you ram you can do what you want in the end, but try to get a standard number like 1600, 1866, 2000 etc. biggrin.gif good luck

Yes, so 9c, probably vcore. I'd remove your 48 on core 1 and run 47/47/47/47 to see if everything works then, it seems like a bad idea considering i need to add like 0.07vcore for 100mhz at that point? It's quite wasteful to use high enough vcore to run 48x on some cores when the cores at 47x have to use that high vcore too, but can't run @48x

Temps are fine so why not tonguesmiley.gif
Now I am trying to see if I can get a 49x multiplier on core1 with 1.4Vcore 2,15VCCIN and the other cores on 47x. I suspect I am having one bad core that messed up my other try at 1,4Vcore 2,15VCCIN and a 48x multiplier on all cores. When I found out what the bad core is I will probably keep that one at 47x and the rest at 48x (or 49x?) unless I have multiple bad cores. Anyone else done something like this? Does it work out?

If you can manually set multi for core 1, 2, 3, 4.. maybe it's good. How are you doing that?

Turbo multipliers that raise 1 core speed act in a rather unpredictable way (if i remember belial's rant correctly) and you can't actually stabilize higher core speeds with them because they raise speed of whatever core they feel like and you have to use extra vcore anyway, but sounds like you have more manual control?

I know there's a 3770k a couple rooms away from me that primed @5ghz, 1.35v for a few fft lenghs on 2 cores when i tried it out, but barely booted at ~1.33 with all four cores up, so i got better results there. I tried such for my 4770k and didn't see the same gains
