ASRock Z77 VRM/phase cooling badly needed - Page 2

post #11 of 34
Someone pointed me here since I have this board also, I have no issues my self.... idk anything about capacitors/vrms though admittedly this is only my second custom built pc.


I have never bothered to check how hot a vrm is, for one I don't have a laser temperature checker so idk how i'd tell if it was too hot. I can tell you this: I don't suffer from any problem priming, if my vcore is enough I will not BSOD/ have a worker stop in prime (even if the temps are 95c+ on the cores). Maybe that dude just got a bad board or his 2500k is somehow responsible?

my case cooling is like this, 2x 120 MM front intake. 1x top 120MM (switched to intake recently) hyper 212 evo 120MM fan on front of the heatsink (is this considered push or pull?) 1x 80MM (I think its def smaller than 120MM) rear exhaust. and obviously gpu/power supply has fans too. I dropped the 2x 120MM side fans cause of noise / diminishing return and haven't had any issues. afaik nothing has ever overheated on my board in the 5+ months i've had it at this point

They use Renesas PowerPAK VRMs.

Well, he has a Sandy Bridge CPU which has 95W TDP, to start with.

I have a very good 2500k I think. It scales very well until 1.3v then it seems to go crazy, random BSODing after longterm testing in a row. The BSODs stop when I leave it off for a while.

Holy crap the VRM gets hot on this board, if I had stumbled across this post before buying this I would have just saved up the money for the 200€ Fatal1ty version with more power phases and much better VRM, starting to look like a pretty awful board to me this Extreme 4 compared to the P67 Extreme 6 I had frown.gif

I'd just have steered clear of asrocks. The extreme 4 has pretty sub par mosfets that really shouldn't be used these days anymore. And even with those, asrock boards report lower volts than they're actually running (well at least many of them do, including the extreme 4).

Well that would also explain why it is stable with "less" volts than my P67 Extreme 6 was (Which was frankly a ****in awesome board compared to this ****...)

Had I know about the ****in ****ty mosfest, I wouldn't have thought twice about putting 200€ on the Fatality version instead, or another manufacturer all together but I got no clue about their boards.
(Seriously, no review meantions it unless you specificly look for extreme4+mosfets on google...)

These days you shouldn't rely on 99% of motherboard reviews since they don't even mention anything about VRM mad.gif. P67 Extreme4/6 are epic. True 8 phase digital VRM design compared to 4 phase analog design doubled to 8 with D-PAK mosfets on Extreme4...

I think it is mixed, digital steering but analog measuring or something like that, at least not simply pure analog.

They call it hybrid, if not only for marketing. Some makers really demand analog PWMs, some demand digital. A lot of older engineers like analog b/c it i simple to implement and doesn't require firmware.

This so much :l The P67 Extreme 6 that died on me was awesome on every level compared to this frown.gif
