Help! I'm having a really hard time O/C with my new rig

post #1 of 4
Thread Starter 
Well I received my new parts yesterday and took the entire day assembling and installing windows.

OS : Windows 7 Pro 64bits
Case : Cooler Master HAF X
PSU : Corsair 1050w
CPU : Intel i7 Ivy core 3770k
MOBO : Asus Sabertooth Z77
Cooler : Noctua NH-D14
Memory : 4x4gigs of G.Skills Jigsaw of DD3-1600 F3-12800CL9
Video Card : 2x Gigabyte GTX-670 OC Edition
SDD : (Recycling my old Crucial C300 128gb)


I installed windows and a few programs, once the PC was stable I started trying some overclocking. Changing multiplicator from 35x to 49x right away (4.9ghz), with a 1.38v VCORE. Right away I can tell something is wrong, in the POST screen it still says my cpu is @3.5ghz. I go to the bios to check my temps haven't changed and the multi really is at 49x.So I get it in windows, but even tough my temps were below 40degrees I got a few blue screen so I toned it down to 48x with 1.35v and now it has never crashed.

CPU ID Shows my cpu Core Speed being at 4.8ghz. But under "Specification" it says :
Intel(R) Core(TM) i7-3770k CPU @ 3.50ghz. Other applications such as 3D Mark 11 report my PC running at 3.5ghz aswell... what's going on? Is it O/C'ed or not?

Well after a couple messing around I shrug it off and give 3D Mark 11 a try. I get the worse score ever. I wonder, wth? A quick comparaison with a good score explained why. It says I'm running with TWO Cpu Cores instend of four?!!!!? Wow I went in the bios put a bunch of stuff back to Auto, removed the overclock, default VCORE.. still same thing each time I boot now my computer only has 2 cores.... !?!?!?! I've been googling/reading a lot of stuff, but 2cores on my IVY bridge nothing comes up for that.. Oh PC Wizard and taskmanager apparently show activity from 4 cores... this is f'ed up

On top of that my gigabyte 670s are suposed to be @ 980mhz core, and multiple programs report the core running at 751mhz.

Sight.. here is a screen I just took:

edit: I cleared CMOS booted with default setting and it still says 2 cores

Only thing I did with my ram in the BIOS is put the primary timing shown on my box : CL9-9-9-24-2N

Resolved the biggest problem of all.. # of cores.
run > MSCONFIG > advanced options > numbers of core

So here's the thing.. I had this set to 4.. but apparently this screws up everything.
Unchecked the box, reboot, CPU-ID now shows 4 cores.
