Asrock P67 Extreme4 UEFI & Drivers thread [Extreme6 & Pro3 owners welcome]

[Ket]

okay .. thanks for the quick reply. hmm.. Im using third party cooler... the the load temp were good.. using the OCCT and prime95 to test.. . never even went past 60c... mostly in the range of 54-58c for all for core ..

may I know which temp monitor software as of current is able to give the correct temp of these sandybridge..

I realized that the realtemp 3.60 was like outdated.. last year oct.

I use CoreTemp 0.99.8.

Hey guys, I recently purchased an Asrock P67 Extreme6 and a Core-i5 2500K as part of a new system build a while back. I've been lurking in the thread for weeks (I've read every single page!)

My goal:
I want fixed OC @ 4.7ghz (or more), with all power-saving features off. I will not be browsing, checking e-mail, or anything else on the build; it is ONLY for performance. I'm posting this on my separate 24/7 machine. The Asrock P67 Extreme will be used for performance and ONLY performance.

Anyway, here's my problem:
I can't get stable/boot past 44x multi.

These settings work beautifully:
- All C-settings off
CPU ratio: 44
PLL Overvolt: Disabled
Speedstep: Disabled
Turbo Boost power limit: 250/250/1
Add. Turbo Voltage: Auto (can't disable)
Core Current Limit: 250
BCLK: 100.0
Spread Spectrum: Auto (should I disable this?)
Power Saving: Disabled
CPU Core Voltage: Fixed/1.375v
LLC: Level 3
(all of the following @ AUTO: here are reported values)
DRAM: 1.635v
PCH: 1.059v
PLL: 1.832v
VTT: 1.142v
VCCSA: 0.925v

These settings 100% stable in IBT, Prime95 (blend). BTW, temps are a non-issue; load barely touches 60C on medium fan setting w/ Tuniq Tower 120 Extreme.

- @ multi:45, I eventually fail Prime95 (blend)... Oddly, upping vcore does not seem to help (should I try the other voltages?).
- @ multi:46, I get black screen with flashing cursor after POST. Upping the vcore to 1.4 makes no difference. What the heck is going on?
What settings do you guys recommend?

My specs:
Core-i5 2500K (Tuniq Tower 120 Extreme)
Asrock P67 Extreme6 (B3)
2x2gb DDR-2133 on XMP profile (G.Skill F3-17000CL9D-4GBXL)
XFX Black Edition 750W
Windows 7 64-bit
-----------
Secondary issue (nowhere near as important)

I have a Toshiba CDRW/DVD drive installed on SATA port 2 (just above the ports 0/1), but for some reason it reads discs VERY VERY slowly. It also causes Intel Rapid Storage to hang for several minutes when Windows loads up. The drive works perfectly in other builds.
This sounds a little like the infamous SATA port issue, but my MB is a B3 model...so what's up?

- Enable PLL overvoltage
- Set LLC level 2
- Change PLL to 1.85v
- Change VCCSA to 1v
- VTT doesn't need to be that high
- Dial in 1.36v (fixed mode)

Now try booting 46x multi. You may just have a bum 2500k.

As for the other issue, try a different SATA cable and/or optical drive. Slow disc reading is ually the cause of a dirty laser, dying drive, or a bad cable.

As of the argument:
"if it was a problem with either Asrocks boards or the P67 chip itself there would be many people complaining about it."
Please try to find in the Internet any and I mean any person with Asrock P67 board using hardware raid card with or without success. Good luck. This is simply a niche market. Nobody reports because (almost)nobody uses.
Please try to find anyone using Asrock P67 with hardware PCI or PCIe DVBs(2) SAT card. Good luck too. The same applies.

1. It wasn't a argument.
2. Don't act like a toward me, I'm not a Asrock rep just a mediatary passing on info I get from my contacts.
3. RAID cards being used isn't that abnormal, I'd think any decent RAID card (or most at least) and not the cheapest you can possibly find would work in most boards. If hardware is cheap, its usually cheap for a reason (lack of QC, little to no driver updates, little to no tech support, etc).
