nilssab it is your responsibility should you decide to overclock. Nobody can tell exactly what may happen. I pushed it to 4200mhz at 1.40V. GPU- 1086mhz at 1.3V Below is the result of Prime95 (closed mini itx case!) after 12-15 minutes. Used to OC the APU to 4.5ghz, using Biostar A85W, but no much difference; and didn't like it at 1.5V.
What really matters is GPU overclock and fast memory.
Also, covered the south bridge up with a custom made heatsink (that used to be a socket A cooler). Never hurts.




some mods to the case (IN WIN BP655.300TB3L)






Cable management would've been better had the audio cable been longer (the grey cable above the cpu fan). Cable ties helped a lot. Thanks home depot.







Prime95 (in Biost the temperatures were lower after an hour)



The mobo seems to be solid. Can recommend it to a friend biggrin.gif

Does anyone know if raid cards work in the PCIe 16x slot. I want to pick this up and an LSI HBA SAS controller. I've already ran into an issue with an E35M1-I failing to recognize the SAS controller I have (LSI 1068e based sas3444e).

hmm, well I guess so, but in this case its even printed on the card DDR3 2600+.. I really wonder how they achieved that.. I tried to lower the multiplier and work on the base clock, but got unstable as early as 105MHz.
and even if I understand that the responibility is mine its the first time a motherboatd sets the limit in this way for me, so what I esentially want to know is if I should observe unstability from the clock before it becomes a hazard to this board?

I guess things are different now with the NB in the CPU, earlier the NB would overheat and get unstable before there was any real risk to the board save for long term wear(like lifetime reduced from 10yrs to 5yrs or something) but if you managed to make a 4.2 clock with the fm2a85x and the vrms etc are still cool I think I'll be able to play around a bit without taking too much of a risk..

Edit:

Looks like 2400Mhz is a no go. I could pass HCI memtest but I am getting random freezing /locking during games. I backed off to 2133 for now but was able to up the GPU to 1030MHz. I've also mimic'd the A10-5700 CPU speed settings as I'm shooting for a reduced wattage small enclosure setup. I still have my magic 30nm Samsung's to try out.

Hi guys, small update.

I received my Mobo and new RAM + Noctua cooler. I realized pretty fast I can't install my new Noctua cooler NH-L9A as it requires a damn backplate to be installed but these motherboards don't allow for that a they don't follow AMD standards for socket clearance. I think I may be able to rig it up using some plastic washers but i'll likely need longer screws as well.

Anyways for now I'm just using an older stock AMD cooler for the A10-5800K CPU and have disabled turbo boost and running it at 3400mhz with a voltage of 1.35 volts (undervolts to 1.32 according to CPU-z under load).

Some good news - So far I have that new G.Skill RAM (F3-2400C10D-8GZH) running at 2400Mhz at SPD timings (10, 12, 12, 31, 1) stable albeit with no long term stress testing. I had to increase the NB voltage to 1.45 and the DDR voltage to 1.67 to pass heaven benchmark and am now running 3 iterations of HCI memtest which I'll run for a few hours before I call this really stable.

I can tell you that compared to the A75 ASRock ITX this thing has a proper voltage setup and heat seems to not be an issue. Even while running 3 iterations of memtest I can keep my finger on the heatsinks which only feel warm. This is a huge improvement over the the 75. I guess if she dosen't blow in a few hours I'll know it's a win smile.gif

Anyway, if you guys want any specific testing let me know. I'm tight on time but may be able to run a few tests over the next few days.

So far so good! thumb.gif

I'm also getting this motherboard in day or two. I was planning to use Noctua's NH-L9A with it, but like poster before me said, it doesn't fit. So I'm now kinda wondering, what cooler I should get... most of the cooler brands don't show compatibility lists on their sites like noctua does =/

I'm getting it for HTPC use, so I'm not sure if the stock cooler is quiet enough with my A10-5800K...

Hi, why not try Thermalright AXP 100, I believe it can be installed without a back plate!
post #77 of 213
Any cooler can be installed without a back plate. Just use some washers. Mine weighs 330g-not a problem.
post #78 of 213
hmm, washers sounds like a good idea, I was using a scythe mugen 3 on my a75, the backplate does cover some components, but it has a 2mm foam to relieve such stress, so I just let the components get pushed into the foam, so you could probably do that too.
I have rubber sheet and washers so I'll probably go with the washer path, most itx cases mount the motherboard horizontally so there shouldn't be any problem..
post #79 of 213
I think I would want something a little more puncture-proof than foam!

Hello,

Could you try with the samsung sticks, and see how far an overclock you can achieve? This is very important for me as I'm about to purchase yet ANOTHER set of DDR3 RAM, just because I've been hearing that those samsung ("magic") RAM sticks don't do well with this APU platform (had already bought them though).
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?
