3930k not taking any OC - Page 2

post #11 of 17
Thread Starter 
OK update, I set the bios to default which means it sets most things on auto. I changed back the vcore to 1.395 and set the turbo boost to 40 for all 6 cores and set to auto. CPU-Z shows 4ghz clock speed on prime 95 no crashes. However when I set the turbo boost to 45 it crashes. When I disable turbo boost and increase the multiplier to 45 it crashes. Mind you the system is water cooled. so right now I have turbo boost set to auto with all 6 cores at 40 with a 32 multiplier which seems to be stable. Im not sure if this is a hardware issue or a setting, possible voltage related. I'd gladly take a screen of my bios but i have a crap wireless keyboard and mouse and it says the bios cant find the USB key...I did however write the settings down.

I should also note that I have the memory using XMP profile one which gives its rated speed of 2133, also voltage is at 1.650. Not sure if memory will affect the CPU overclock stability.

In my experience XMP profile can screw up 3930k overclock.

I would suggest setting your bios to manual. Also, I have had a difficult time with high memory overclock and high cpu clock. You are going to need to up your VTT and VCCSA likely to achieve higher memory clocks with higher CPU clocks. DO NOT GO ABOVE 1.2V FOR EITHER VTT OR VCCSA. This will degrade your 3930k.

I currently have my 3930k set to Turbo ratio set to 47. VTT and VCCSA are set to 1.13. My ram is set to 1833mhz (It is the max combo I could with that ratio). Vcore is set to 1.395.

I would also try changing things such as LLC to high for Vcssa and CPU can help (and any other LLC setting for that matter). Also increasing current capability to 130% or 140% helps (I cannot remember which I can check when I get home if you'd like).

So the instability could be because I am running the ram at 2133 as well as the CPU at 4.5? The memory I have is rated for 2133, is there another way to achieve this without using the XMP profile? Also my VTT and IMC are both 1.1v.

The system crashes to the bsod 101 whenever I change the multiplier even by 1. I really don't understand it unless its a faulty chip or board. Prime 95 still instantly freezes up and the system crashes. The only thing I have been able to do is set the turbo boost to 40 on auto which holds and runs prime 95. Setting the turbo boost to 45 crashes. This is so frustrating I really hope its not faulty hardware.

I have a stable overclock at 4.3 using turbo boost set to enable. I still cannot increase the multiplier at all. When I set 43 as the multiplier its crashes. When I set the turbo boost at 43 it runs prime95.

Still running stable at 4.3 with turbo boost. I might try and re flash the bios maybe its corrupt? Does this sound like a hardware issue? Or a bios issue?
