Equipment
CPU: Core i5 2500k
Cooling: Cooler Master Hyper 212+
Motherboard: ASRock P67 Extreme6 (updated to latest BIOS)
Memory: 4GB DDR3 1600Mhz G.Skill Ripjaws X
Video Card: HD 5770 + HD 5450 (for multiple screens)
Storage: 1TB Spinpoint F3 7200 RPM + 1TB Hitachi Deskstar 7200 RPM
Case: Cooler Master Storm Scout
Intro
I have been googling (and searching in these forums) for quite some time on this specific bios/motherboard. There doesn’t seem to be too much information out there, unless I’m just missing something. I’ve seen where others say it was very possible to get anywhere from 4.5 to even 4.8 24/7 stability for the 2500k on this motherboard. However, those posts don’t show what specific BIOS settings they have been using. I’ve been turning on/off my computer trying to guess what I should keep on for about two days now and I haven’t had much luck.
At first, I would either just get BIOS to POST, but couldn’t get past the Windows boot-up. Thankfully, I haven’t had to clear CMOS once yet. Then, I finally got it to boot Windows, but it would either freeze, shut-down, or BSOD when I was about to log-in to my Windows account. Now, I got it to boot at 4.5 but there are still a lot of things wrong with it.
It seems to be sticking at 4.5 at idle, as you can in the pics.
Here are the BIOS settings I have for this particular set-up:
VCore – this seems to be fluctuating on CPU-Z even when 100% usage on prime95, as you can see in the pics above
Load-line Calibration – I don’t see an option to disable this: it only allows me to set it to Level 1-5, and Auto:
Host Clock Override (BCLK) – I set this to 101Mhz because it wasn’t at a firm 100Mhz in CPU-Z even when it says so in BIOS; I read in other guides that people upped this to get a stable 100Mhz
PLL Overvoltage – I disabled this as suggested by many other guides. But there is also the option for CPU PLL Voltage underneath which is set to Auto. So, I’m not even sure if this is still on or not.
C1E, CPU C3/C6 State, CPU Thermal Throttling – I also disabled these as suggested by other guides.
RAM settings – I left these at auto for now; but the modules are rated at 9-9-9-24-2T (at Auto, I think they are using 9-9-9-24-1T as you can see in the pics)
I tried to put as much as effort into this post hoping someone could help me, and that maybe some others in the future could benefit from this as well. If anyone could help me with this, it would be much appreciated. I’m starting to get a headache.
I was using a P67A-UD3-B3 rev.1 before getting this “upgrade” and getting 4.8 stable at 65C, even though I didn’t have manual control of VCore. I wanted control of VCore and hoped I could get it higher and now I’m having second thoughts.
