I'm not too experienced with the i5/i7 platform yet to say if it's worth it (I just upgraded). I would say it's a different way of doing the same thing. OCing the BLCK is going to oc other components though and as a whole make your rig run faster than just the multiplier. That's up to you though. Now for it shutting down... that could be a few things, but most likely indicates your OC probably isn't stable. Try setting a ram profile as XMP and setting your multiplier to 45 with an offset of .030-.050. The above advice is good, but I think you're playing with too many things yet.. that you don't really need to touch. Anyway, try that offset and back-down from there until not stable. The word "stable" can vary too. You can be "stable" for your use and purposes such as gaming... or 24 hr + benchmark stable. That again is up to you. I'm rambling a bit, but take your time and try resetting your overclock little by little. Check youtube as there are helpful videos as well, rather than just reading walls of text.

I hope that kind of helped. As I said, I'm new to i5/i7, so I don't want to give too much advice yet. Good luck! thumb.gif

Unfortunately things have gone worse in general... I wasn't getting BSoD on IBT until i tried prime95 with the same message about "A clock interrupt was not received on a secondary processor" etc. Also as soon as i get to desktop my USB's (mouse, keyboard, pendrive) aren't recognized or don't work after a few seconds until they do...

Edit:

As of my latest config i managed to get rid of BSoD and USB problems but my PC still shuts down once before turning on, any idea what exactly is causing this or how to narrow it down?

Hello people I'm back after a lot of testing. I decided to go for 4.4. GHz for the sake of temps and OC 24/7. But i got one question, i still get the BSoD under high stress tests, i already found the sweet spot on the vcore to be 1.336 but i have a problem, when i do the stress tests the vcore goes up as much as 1.344 and as low as 1.328. The problem is that once it goes to 1.328, it seems too low for the stress tests and at some point it gives me the x01 BSoD which is lack of vcore so what i want to know is what config do i want to try in order to keep my vcore steady under load and I'm also wondering if its a good idea to have a steady vcore 24/7? I'm not using EIST nor C1E, what am i missing here?

you should email your motherboard maker about negative cpu multipliers in the bios. thumb.gif

What do you mean, can you be more specific?

I would set Clock Gen Filter to 10uf for 2133, I use 20uf for my Ripjaws Z kit which I run anywhere from stock 2133 9-11-10 to 2580 10-12-10-26 1T and at 20uf I can get away with a max DIMM voltage of 1.655v for the highest speeds, but without I need at least 1.735v. I have never had to run more than 1.165v VTT/VCCSA either.
Keep voltage as low as stable, even the secondary and tertiary voltages, as they can really contribute to heat. That said, I would rather run 1.365v core and 1.175 VCCSA than 1.4/1.1 respectively.

I have my 3930K @ 4896Mhz with DDR3-2284 9-11-9-26 1T, with just 1.365v core.... I would be happy to give you my BIOS settings when I gethhome, although what works for me may be very different from what works for you, both due to the differences between chips and the fact we have different boards (although both Asus).

FYI, after a couple of BSOD's while working of course (referring to my earlier post about topping out comfortably at 4.4Ghz), I upped VCORE to 1.31 and VTT to 1.15). That's about it. Nothing detailed. I also kept EPU enabled. Has worked like a charm since while Avid and After Effects are churning. Benches don't throw up flags.

Temps are hot (44c min 77c max, 82c max in prime [edit- hovered around 49-55 doing light work) but the ambient was 37c today. Almost 100F outside today and the room ventilation loops to exterior air on only 210cfm. Eh, summer.

Honestly don't think you need to get very complicated to be stable at 4.4 under even harsh conditions. Of course take that with salt.

Cheers!
