I might not really understand what it is you meant, but it's a regular steel backplate, the motherboard-side of the backplate has a plastic film for insulation and the part around where the screws will add the most pressure is covered in a somewhat soft foamy plastic. This also happen to be where a chip (can't remember which) and a set of small components are in the way of the backplate. But since the backplate has a foam the components will not be directly pressured by the backplate and if heat is no problem for the chips in the way it should be fine.

Are you suggesting that the components could penetrate the foam and short to GND? I have to check again if there is a thicker plastic under the foam in that case.

Edit, it has plastic covering the whole metal part, and foam on top of that (https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTRrRihEqJyFU_2cxkEU1xhwKlWzvZFc6z5ernqGX9UcBBlVs9C)

Also you say that you've been able to use those (rated) 2400MHz sticks, if I read that correctly. Is everything stable at these clock speeds?

Also, I don't get it; we cannot install ANY aftermarket cooler that has its own backplate? That's pretty much ALL coolers! I've also purchased the Zalman LQ-310 cooler which I intend to install on a mini ITX case. Would that mean that I'm screwed, and need another cooler? Why is that?

It should be ok with washers if your board will be mounted horizontally or if the heat sink isn't too heavy.
Or you could like me use something with foam on the backplate, I immagine that's a common case.. I use Scythe Mugen 3.

Yes I'll try the Samsung sticks soon, maybe this evening if I get time. I could not achieve full stability at 2400mhz with my G.Skill sticks so I backed off to 2133 for now but I have some more room with voltages to play with. I don't think it's the RAM though, I think it's my APU that is having trouble at this speed.

Good news about the Noctua cooler. I was able to mount it securely to the ASRock using rubber spacers on the back side of the motherboard along with the steel back plate. This was enough to just clear the surface mount components which is what you want so you have enough thread left on the screws. You don't want to over-tighten the screws or you could crack the PCB area under the APU. I spoke with a Noctua engineer who said this should be OK but they will not be responsible for any damages as the board is not officially supported. With the Noctua installed it works really well and keeps my temps under 60C plus due to the size you have the added bonus of cooling the surrounding components. I'm very impressed with it and can recommend it for this board, just be careful with the installation.

--

My system as currently configured:

I did some basic power measurement tests last night with the APU running at 5700 CPU speeds but under-volted to 1.285 volts on the APU and 1.375 volts on the GPU as well as 1.6 volts on the RAM. I kept the RAM at 2133 and the APU at 1030 mhz for these tests.

Power supply is an XFX 550W Core Edition which is an 80+ supply. According to reviews at it maintains 80+ efficiency already at 100W though with a Pico PSU these numbers would be much better.

180GB Intel SSD 520

2 sticks (8GB) of G.Skill DDR3 RAM.

Skyrim running at 1920/1200 (16:10) with high detail settings drew at most 112W but averaged closer to 100W.

Prime 95 large FFT drew 95W.

Occt CPU + Heaven drew 135W!

Idle power usage is a little high at 32W.

So given the efficiency of the power supply I guestimate my current set-up is drawing roughly 110W in total in a worst case scenario but likely closer to 90-95W under heavy loads. If I back off my GPU overclock, switch to my Samsung sticks and lower the volts to accordingly I'm thinking I could keep it closer to 100W max for worst case scenario draw but I want to keep performance as high as I can.

This will take some time to get right but it's looking like I'm going to want to buy a 160W Pico to give me the headroom for dual graphics and future FM2 processors.

160W pico wont give you enough headroom for dual graphics. its only just enough for an overclocked A10. remember you are pulling 135w at 3.4ghz and that only gives you 25w overhead.

IMO you get better gaming performance per watt while keeping it minimal if you downclock the CPU and give that TDP to the GPU overclocks

my power draws are still way past 100W while running at 1.15v on the CPU and GPU

btw i've no issues installing the zigmatek preaton on my board given it has the same layout and design. the stock mounts are easy to remove and you just need to thread your screws through those holes

Hope you don't mind me asking you, but you've got a setup that I'm rather interested in. Have you got the new Praeton LD963 with the 3 nickel coated heatpipes or the old one with 4 heatpipes, the LD964?

What are the temperatures on load with that cooler and what clocks you got on the CPU/GPU?

Thanks.

Its the triple heatpipe preaton.

load temps around 65c. im still experimenting with my clocks but CPU currently is at 3.5ghz and GPU is at 950mhz. im still trying to get more GPU clocks

Mine came in today and I spent the evening testing it out and preping my LSI controller. My use for this build will be a nas4free setup with 4 internal 2tb drives and 4 external 2tb drives via sff8088 sas expansion (sans digital).

I was worried the LSI SAS 9112-4i4e wouldn't work; it was kind of a gamble because I couldn't find anyone with an ASRock FM2 board using an LSI controller to confirm it will work. Luckily the controller is picked up by this board, however there doesn't seem to be a way to enter the LSI configuration utility during POST.

Good thing that won't be an issue since I was able to flash the controller to HBA target initiator mode, so I won't need to setup any JBOD, and freebsd will see my drives natively (it came with integrated raid firmware). Although I had to flash it through the EFI Shell (got "Failed to initialize PAL" when trying to flash in DOS). Also for some reason the screen would not scroll while in EFI Shell, I had to use scroll lock / page up / page down to see my command output.

I also messed around with under clocking the A6-5400K paired with this board. I had less then good results. I was able to do turbo off, 1600 MHz, x16 multiplier @ 1.15v and graphics core at 460MHz @ 1.27v - Windows Idle was about 52 watts.

Yet at stock settings, with turbo off Windows Idle was about 47 watts.

I'm trying to get it close to power usage of an AMD E-350 APU; that setup idles in windows using about 42 watts. So I think I'm just gonna run with stock settings / turbo off for now. I still need to check power usage in nas4free.

Other than that the board runs cool, the BIOS is decent and has good voltage options, and not to mention the 7 sata ports on board smile.gif

what sort of PSU do you use? your idle is pretty high IMO. you should be able to hit around 30-35w or atlest thats what im getting with my A10 though i'm only running a SSD + 2.5" 7500rpm drive

i do realise that an inefficient PSU will give higher wall readings as i've been measuring my pentium G620 with a crappy PSU with just a single HDD is pulling 65-70w idle while an i5 3470 running a 3.5" drive + 2x 2.5" drives is pulling around 35w idle and an i7 3770 with 2x 2.5" drives with a GTX670 at idle is only around 50-60w

not too sure how much my E350 HTPC draws as i havent bothered to measure that

Thanks, just received mine in the post today (the cooler that is). That's a bit too high for this cooler it seems, for my liking anyway. Not sure if I should go for this or stick with a slightly bigger desktop build where I don't have to compromise on so much apart from the size.

It's temporarily in a test case with a Enermax 600 Watt Noise Taker II (http://bigbruin.com/reviews05/enermaxeg701ax/). I'm going to have to try another power supply; like you, others have also stated to be able to get 23 - 35 watts idles as well.

my temps are high because of the fan used and the orientation of it.

for starter im not using the original fan nor does my fan fully covers the heatsink, the fan is a slim scythe fan so it deosnt push much air in the first place and my fan is in "pull" orientation so the fan effectiveness is mostly gone. i had to orientate it this way due to the case and the air flow.

the zigmatek can accomodate a standard thickness 92mm and it seemed to work better

none the less 65c max load temps isnt that bad

seems like a old non 80+ PSU, its probly why. i was running a old thermaltake PSU (its bad i know) to measure the power for the pentium rig and had a shock due to its high idle. my other rigs have decent 80+ PSUs like the one from the SG08 and a seasonic x-750 so the power draws at idle is low
