Mind sharing what your other voltages are?

My 4.5 score is the same as your 4.6

Cinebench @4.8...

Note: Uncore not stable. Not sure if uncore makes a big difference. Think that last run with 10.29 was with uncore left at x39.

Uncore makes a little difference, not much as long as it's "up" in general to like 4ghz, RAM makes a pretty big gap though. I might be able to hit 10.5 on 4.7 with tightly tuned RAM and a lot of work, i didn't get over 10.4 easily though..

If your RAM is a 1333 9-9-9-24 kit and it's not just set that way, you might wanna even throw in some faster stuff and tune it, it's worth a lot more than 100mhz on the cpu core clock

What is "WHEA_UNCORRECTABLE_ERROR"? Looking around it seems related to vcore, but I can set the vcore to 1.4 v with a multi of 47x and still get it. Unless I have a terrible cpu, I feel like I am missing something. I see everyone with a vcore way lower than what mine needs at the same multiplier.

If you're an AMD overclocker, maybe you're not familiar with recent trends on intel cpu wink.gif

Some CPU's will do 4.3ghz on 1.3v, others 5.0, but it's not too uncommon to have a chip that can't do 4.7@1.4, especially with other untuned voltages. You gotta go quite slowly with haswell unless you want to fall into the trap where you are unstable in three different ways, but it's impossible to know if you have fixed one because another one is tripping you up, even with water i'd start slow, taking a few lower clocks first

Whea uncorrectable (0x0124) is usually vcore, but if you're throwing settings fast it could be from something like too low ring voltage, if you're trying to clock hard suddenly then i'd say just set 1.2 ring and 34x uncore, deal with uncore afterwards. Also, you can get setting +0.05 or +0.1 digital io vs auto, but be careful because sometimes auto works on sa/aio/dio voltages while +0.1 for example does not. I'm not sure why, but some of my oc's refused to work if i manually altered them, but it's quite common to raise digital io

If you're not tuning VRIN properly, your chip will also demand far more vcore than it needs for any kind of stability, as a quick guideline throw llc on it and keep it ~0.5v above vcore

Yeah, RAM's set at 1333Mhz for now till the CPU's done. G.Skill TridentX 2x8GB@2400Mhz. Hoping it will perform well!

Have you checked vcore/vrin voltages with a multimeter? Stuck one on it now and seem to get +.02v off the board compared to XTU. Just goes to show the HWM readings are fairly accurate. Is there a reason why there's such a difference between set voltages and actual?

With regards to vrin & uncore multi, is it wise to have the vrin higher than vcore? Vcore is reasonable for x48 on the cpu @ 1.245, actual of 1.265. I failed with uncore at x45 1.2v 4hrs into XTU and trying again with it raised to 1.22v (1.24v actual off the board). Wondering if it's worth trying to raise uncore higher which will obviously need increased vrin but from what i've read on the forums it's probably not worth the effort.

VCCIN i've set at 2.0v for now but i'll dial that back down once uncore is stable. x48 on the cpu was done at 1.9v. With uncore raised will that help stability with the cpu? i.e, lower vcore for same multi/increase multi with less vcore?

Cpu-z shows the CPU vid not the core voltage, or?
