these are the VRMs right? I placed some heatsinks here and have a small fan sucking from this area. I do notice a difference but it still throttles after a while. before it would go from 4.3ghz to 3.3 and then 1.6.
It's been running for quite a while now. I've found the same thing as you guys have...it throttles to 3.4GHz in Prime95 after about 20-30 seconds regardless of what clock you have it set at. I've tried a bunch of settings but I've settled on the generic "Turbo 4.3GHz" mode in the BIOS as it seems to work well. I'm not sure what it changes behind the scenes but it sure seems like it gives the board a little more time before it pulls back the multiplier and anything I've tried in the BIOS hasn't replicated it. I wish it had a turbo 4.4 and higher so I could give that a shot.My board is here but I'm still waiting on ram from Mushkin:

The pair will be replacing an H67 ASRock board in an existing system. The rest of the build:
2600k
Scythe Samurai ZZ cooler
Silverstone SG07 Case
GTX 590 driving a Dell 30" Monitor
120GB OCZ Vertex 3 SSD
I believe those are the chokes, the small black ones beside them are the mosfets. I think the mosfets get hotter and need cooled, referencing gaming boards have heatsinks on them and not the chokes.
Howdy,
What is the best Blue Ray burner that could go with this board? IDE or SATA?
Cheers

Is there any off the shelf/cleaver way to cool those mofsets? I'm not sure there is a simple way to get air over there in a SG06 since I'm running a H60. :\
is that silver bit where the asrock logo is on the blue heatsink removable by any means(without damaging the board)?
Just got this board set up, but when i pressed power nothing happened...excepet the fans came on. I got no bios screen from any of the outputs, no lights on the board, no beeps, just fans. Did I get a bad board, CPU, both?
It's held on by two of those spring mounted plastic push pins, you can just about see them in the picture a few posts above yours. A pair of needle nose pliers to squeeze the pin ends should be all you need.
actually ment just the silver bit while keeping the blue bit intact and in use
I just installed these on the MOSFETs. They're not a 100% fix but they were a significant improvement. On "Turbo 4.3GHz" mode in Prime95 it used to scale back to 3.4GHz after 20-30 seconds and I recorded right around 50 seconds now (CPUID Hardware Monitor shows 104-105W sustained) compared to 20-30 seconds before. Additionally it now consistently tries to ramp back up to 4.3GHz...staying there about 1/4-1/3rd of the time (it hardly ever popped back up to 4.3GHz once it got heat soaked before).
anybody tried the i3 2125 on this mobo?
Come on! I didn't want to OC the CPU, I wanted UC the CPU...lolAs we mentioned earlier, the BIOS of the Z68M-ITX HT while offering the normal "OC Tweaker" section, is lacking the ability to adjust the voltage on the CPU side of things;

All of that testing was with my SG07's 180mm chassis and CPU cooler fans on auto so they had to play catch up after the heat already had a head start. With the fans locked on max speed I got 73 seconds of sustained 104-105W before it pulled back to 3.4GHz (before it really didn't make much of a difference than having the fans on auto; maybe 5 extra seconds).
It sure seems that the power system on the board is protecting itself and somehow the little MOSFET heatsinks helped out the situation.
BTW...still super happy with the board. I'm not complaining...probably just a compromise/limitation of the form factor.
I had no issues installing an AXP-140 on my Z68M-ITX/HT with video card installed. No special adjustments needed. Installation properly matched the documentation.
Nice to know that those MOSFET heatsinks actually make a difference. I figure your situation is kind of a "best case" scenario because you have that big SG07 case fan blowing down on your motherboard. For people using water cooled CPU coolers in other cases (e.g. SG05) I wouldn't expect the results to be as good because there probably isn't going to be as much airflow over those sinks.
That actually answered my question but gave the answered I feared.
Come on! I didn't want to OC the CPU, I wanted UC the CPU...lol
Sad, very sad.
Really? You didn't have trouble with screwing down the pressure plate? Chumby has an AXP-140 on his board, and reported a problem with that(last post on page 5). If it works without any jury rigging then I'll just get an AXP-140.
Especially as the PSU is blowing hot air down onto the area around the CPU...
Even though I am running at stock speeds with the 2600K, this board is still throttling with Prime95. Just like my Asrock H67M-ITX board did before I added Enzotech heatsinks to the mosfets.
With the H67M-ITX, I was able to make some taller heatsinks by ordering the larger one-piece Enzotech kit and cutting it up with a jewelers' sawblade. I didn't want to spend as much time though.
I've got the Enzotech MOS-C1 Mosfet heatsinks on the way. I am going to use Arctic Alumina Thermal Adhesive to mount them. I want to cover all of the mosfets, so I ended up buying two MOS-C1 kits for $30 total.
ehh.... neither the SG05, SG06, or the SG07 have their PSU blowing hot air in... (well, the SG07 does blow it right into a vent).
Do you own any of these cases?
Correct, I did not have any issues, not even with the pressure adjustment screw. Sample variance might be playing a role in this.
