**[Official]]** ASRock z87 OC Formula + (M) Thread

[xdan]

Nick, can you tell me, there are some problems with stock in eastearn Europe, Romania more exact?
Z87M OC Formula still none sign of it here, as for OC Formula was in stock, 2-3 weeks ago, now it's not in stock.
And also was available at just 2 online shops.

Problems with stocks from Asrock here in Romania were not in the past ...
Alex-Ro has the motheboard from other source not from any local shop.
Want to buy next week Z87M OC Formula to pass to Haswell.

How much CPU input voltage and cache voltage do you think is safe to use for 24/7 on air? I've been testing clocking my new 4670K on my ASRock Extreme6 and vcore wise it seems pretty decent so far seemingly stable (still need more various tests to be sure) at 4.5GHz 1.21v vcore (might go a few 0.01v lower even) but seems to need like 1.2v cache voltage or so (at least not stable at 1.15v cache voltage and will BSOD quite randomly/quickly without stress testing too and I've set CPU input voltage to 1.9v currently. The Input and cache voltage is more worrisome, the vcore isn't worrying (seems pretty low) and temps more than fine ~65C without AVX and ~75C (hottest core, the rest are like 5C lower) with Prime95 and AVX. Phanteks dual fan cooler + CL Liquid Pro for those who wonders, pretty impressed by the cooling capabilities but the cooler costs almost the same as entry lvl WC kits so it better be. :p

Been out of the OC hobby for 3 years, feels like it's changed so much when UEFI appeared and now you can just flash BIOS with a click of a button in UEFI directly from the Internet lol.

EDIT: Seems stable at:

4.5GHz
Vcore: 1.21v
Cache: 1.185v
Input: 1.92v

Seems good enough for me for a start, maybe I push for higher, maybe not, already quite satisfied with that as I always used to get very poor chips in the past

I also hope mobo can be in stock everywhere.

I think that it is depends on the distributor there ...

Maybe distributor wait for the C2 version..
