I know, but OCCT now causes BSOD (014) with the XMP applied...

Perhaps I have to tune some voltage in SA or IO?

That shouldn't happen, have you used the memory sticks with a previous processor with XMP enabled and no probs?

Its all new hardware...

They run fine with stock cpu, I tested 3 times for 8h with memtest86+

How've you OC'ed your CPU currently?
post #5195 of 19540
44x
35x
vcore: 1.35v
vccin: 1.9v
everything else on auto/default

I kept raising vcore 0.01v until it passed 1h OCCT at jedec

vccin was at 1.8v up until 1.36, then i was told it was too low so once i bumped it it was stable at 1.36, I so I retried 1.35v and it passed as well.

Not with XMP enabled it failed OCCT again.

Which BSOD is 014?

I think your chip may need more VCore or VCCIN depending upon the BSOD code.

Without running it on XMP, it runs at 1600Mhz, due to Haswell's IMC's supportage of that speed. With XMP, it does 2400Mhz, but you're saying it fails.

As the XMP profile works fine on stock but causes problems when OC'ed, it looks like a CPU problem, not being stable that is. I can't come up with much unless I have a BSOD code.

Is it just me or for that VCore it would seem like more VCCIN is necessary? Also, I believe using XMP increases voltage ( not sure, I think Darkwizzie was supposed to check it out ).

Anyway I'll check out this stuff today. Have some work to finish up in the morning.

I have my VCCIN at 1.95 for 1.325Vcore, I haven't messed with it it see if lowering it caused BSODs though. I'd try upping your VCCIN to 1.95 and see if that helps.

Well, I tried some overclocking recently. I tested it out on Prime95 running the In-Place Large FFT's test for about 1 hour and 40 minutes. That's about as long as I've tested anything else before.


Here's what I have it at right now:

Is it safe to keep it on that voltage?

I still haven't touched uncore, I think it's ratio is on auto, so I'm not sure if I should bother with that.

I tried it on some lower voltages, but it BSOD'd on 0.01v lower than that in about 20 mins. It's fine for doing, say, the Valley benchmark, but screws up on much above that.

Temperatures while running that Prime95 test capped out at about 80 C. Is that normal?

Opinions?

Thanks.
