^ agreed. tight or loose LLC has an effect on VRIN, SA, IO's.

However, It does not effect Vcore, which always ends up being around ~0.02v higher than VID (in my experience at least). Keep in mind that the software sensors report an estimate of what Vcore is, so if under load your Vcore is estimated as something other than 0.02v above VID, don't stress.

Well I figured I'll give those a go to see if they were the magic sauce I was missing but unfortunately they don't help me. Core x45 @ 1.325v / uncore x42 @ 1.3v with VCCIN @ 1.83v = stable everywhere

If settings are off, up to x45 I get BSOD 124. Anything beyond it's always BSOD 101.

Anyway, I figured I'll use a quick test and run Cinebench15 and if it crashes within 10 runs, it's unstable and no point trying anything else.

x46 @ 1.385v / x42 @ 1.33v with VCCIN @ 1.95v = BSOD 101
x46 @ 1.385v / x42 @ 1.33v with VCCIN @ 2.00v = BSOD 101
x46 @ 1.385v / x42 @ 1.33v with VCCIN @ 2.05v = BSOD 101
x46 @ 1.385v / x42 @ 1.33v with VCCIN @ 2.10v = BSOD 101
x46 @ 1.385v / x42 @ 1.33v with VCCIN @ 2.15v = BSOD 101

x46 @ 1.390v / x42 @ 1.33v with VCCIN @ 2.15v = BSOD 101

x46 @ 1.400v / x42 @ 1.33v with VCCIN @ 2.15v = BSOD 101

x46 @ 1.410v / x42 @ 1.33v with VCCIN @ 2.15v = BSOD 101

x46 @ 1.420v / x42 @ 1.33v with VCCIN @ 2.15v = BSOD 101

Yes, it took more runs to fall over @ 1.42v but that's a 0.1v increase and it's still not stable. My chip doesn't like me and I don't like it, so I then threw XTU Bench at it and it passed but only because it was clicking 100 most of the run and was throttling. Didn't even beat my x45 score!

Are your SA, DIO and AIO at automatic, and your RAM at 1333mhz? Stuff can act weird when you're pushing core and IMC throws 101's. I had similar issues for a while where i couldn't use even 1600mhz solidly (temporarily) on 47x and 2400 would make everything fail like crazy

Also uncore down 33x/1.15v just to be safe. More variables not good. If you can pass everything with 46x core, you can probably bring uncore/memory back up and work out if/where instability exists

Anyone got a link for how much the IPC improvements help through sandy? I'm interested to see how my 3930k stacks up against my 4770k in single core performance.

I'm on mobile otherwise I'd search through the thread and find it myself because I believe it has been mentioned before.

x264 devs quoted 28% (it's a favorable app due to avx2 acceleration etc) but that seems high to me. 15 or even 20% seems no problem though. You can run x264 bench and affinity it to one core

Haswell vs Sandy bridge is good enough to make up half of the gap between 2600k and 3930k, or roughly so, encoding, by some numbers. SB seems easier to clock though.

Sb is so much easier to clock. I went straight for 5.0 lol.

Woke up this morning to boot my computer and I got the asus overclocking failure... I then proceeded to turn down my overclock to 4.3GHz then to 4GHz then to auto none of them helped me boot. Did my cpu die? Ok, got my computer to boot to windows once then i shut down and tried to turn it back on again and it's doing the same thing

I was benching intel XTU on the 2600k pretty recently, not single core but gives an idea of the performance difference



5.5Ghz 2600k above Vs. 4.7Ghz 4670k below
