First I'd like to congratulate Nick Shih on a fantastic product and just say I couldn't be happier with my new board.
I've just finished a modest build on a system with an OC Formula and a 3570K at the heart of it.
I'm cooling her with the Hyper Evo 212 in push pull, and she's running 16 gb of Crucial Vengeance 1866
over an array of hd's (ssd boot) with Win 8 Pro 64. No discreet graphics card yet. I didn't build her for gaming,
but for 3d parametric CAD work, architectural rendering/image editing, and digital art. I consider it a "budget"
high end workstation.
I am so stoked over the performance of this motherboard and chip combo. After some very brief fiddling
about in the bios (I'm not being modest), I managed to squeeze 4.7 ghz
out of her for 12 hours in Prime using the blend test. She tickled 82d in one core briefly,
but ran mostly in the low to mid 70's the whole time at that clock speed.
I basically used Nick's profiles to get me into the zone on this OC.
First, I loaded his 4.5 profile, dialed back the voltage to 1.185 and ran Prime for an hour with no prob.
Same thing at 4.6, with a tad more juice (1.205), and then I decided to see if I could get the 4.7
profile to stick with the voltage set to 1.235. It stuck.
So the old saying goes, if it works, don't fix it, but I'm wondering if there are any temp. or
reliability tweeks I could apply to Nick's "undervolted" OC profile that would make a difference for 24/7 graphics usage?
For instance, should I be concerned that I'm running the CPU LLC at Level 1 (100%) full time? Or, if I install
a discreet graphics card, will that help my daily temps (even though many CAD and graphics apps rely heavily
on the CPU to process their data)? I'm also wondering if there would be a benefit to dialing her back to 4.6 or 4.5
because I can do that at pretty low voltages with this particular chip. Or, like I said, if it ain't broke?
Also, I'm really interested in maybe pushing my little 3750 to the limit on air, just to see what
she can do, but the only problem is, I really don't know what the hell I'm doing in this league
other than the basic stuff. (I might go water or a better air sys. if I get some solid recommendations).
I mainly adjust multipliers and voltages to get where I'm going, but that's as deep as I play.
So if anyone is interested, I might make myself available for some vicarious
Finally, I have to compliment Asrock for a superior product. I bought this board for a replacement of a
major competitor's board that was only 7 weeks old (an Asus p8z77 that RMA'd).
On that board, I couldn't go any higher than 4.5 ghz, and even at that, it was not stable.
Also, the install was a nightmare under Windows 8. On my new OC Formula, everything worked 100%
after the first boot up (I upgraded bios to 1.6 prior to first OS boot).
I'm now stable at 4.7 on air, and I've only spent a couple of low tech hours messing around to get there.
I'm sure with a little guidance and learning, I could get stable at even higher clock rates.
I'm a happy guy.
