Picked up a 4670k, Z87-A and H80i the other day to upgrade my old system. I've been trying to OC it the past few days but I am confused at this point.
Here are my relevant specs
CPU: 4670k
Mobo: Z87-A
RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 1333 (F3-10666CL7D-8GBRH)
CPU Cooling: H80i Push/Pull SP120's
PSU: Ultra LSP650 650-Watt
I've looked around and even asked on other sites such as overclockersDOTcom as to how I should go about OCing and so far things are not making sense. I tried the 1.25v x46 boot to get a feel for the chip and it made it to the desktop with ease. I then decided to tweak things a bit and try a stresstest w/ Prime under the following settings
CPU multi at 45 voltage at 1.25
CPU cache multi at 43 voltage a 1.15
Mem at 1300 7-7-7-21 1t at 1.5v
Speedstep disable
Turbo disabled
C states disabled
LLC set to level 8
I'd run prime for about 14-25ish mins and it'd crash. Tried a variation of other tweaks with that voltage on the cpu but no luck. Only been able to keep 4.2 stable at 1.25v (was too lazy to try it at a lower temp) in prime for exactly an hour.
Also when I first installed the H80i I cleared the paste it came with and applied about 3-4 small dots together of MX-2. My idle temps were in the high 30's to low 40's. When I'd place it under stress even up to 1.27v at x45 (no other settings changed) I would crash after 15ish mins but temps never left the 70's. Now at 1.25v after a few mins it jumps to 80's and peaks out around the high 90's before the typical 20min crash in prime. The reason I brought this up is because since this was my first intel build I was unaware that the 4th core was sometimes 10C lower than the rest under load so I reapplied the paste again twice. The 1st time with a smear method and the 2nd (what it is on now) with the single small drop method. What confuses me about this now is that my idle temps at stock settings are in the mid 20's but under load at 1.25 they make it past 80C within a few mins
I'm aiming for 4.5 since apparently if you can boot with 1.25v at 4.6 it's a decent chip. As of right now it's looking like a below average chip If I'm going to need more than 1.25v for 4.3
Any tips/info would be appreciated. Thanks!
