Asus M5A99X Evo R2.0 Issues

Sorry for lengthy post but please bare with it as I am completely confused right now and in need of some help.

Received this motherboard today and I currently have 2 issues with it so was wondering if anyone knew the causes?

Firstly, I installed the board with my new FX-6300 cpu, which I also received today, and mounted a Artic Cooling Freezer 7 Pro Rev2 but instantly came across my first problem. The fan appears to be working properly (spinning) but bios alerts me that the fan has an error and also displays erratic speeds ranging from N/A to 650000RPM!? :eek:

Unplugged and plugged but with no change, finally resorting to use the stock cooler which resolves the error. Afaik this cooler is compatible with AM3+ boards so unsure of the issue, baring in mind I have had this cooler on an AM3 board for almost 2 years without problems and changed settings on the AM3+ bios. Any ideas?

Secondly, once I had installed the stock cooler I tried to boot into Windows 7. No luck. BSOD's everytime at the exact same moment during the Windows loading icon and have 3 ideas as to why, either the CPU or motherboard are faulty OR the OCZ DDR3 PC3-10666 GOLD LOW VOLTAGE DUAL CHANNEL ram is not compatible with the board despite Asus saying it is?

I do have some new ram coming and will try again once that is installed but as for now I am completely stumped :confused:

As a side note I have not flashed the motherboard bios as of yet due to the fact it is 'brand new' so didn't want to risk it just yet until I have illuminated all possibilities.

Thank's yet again to anyone with information/help

Update

I managed to get into windows, all I had to do was reinstall Windows and BAM! Working just dandy

But now I've noticed my CPU temps are reading as low as 7C or even as low as 5C , have read though that this is to do with the cpu sensor only being accurate during load so it's not really a problem.

Still haven't fixed the fan issue yet which is frustrating but oh well

CPU temperature that low is a DREAM, but seriously you might have to possibly get a replacement, it's a possibility that the sensor is rather faulty. I've used M5a99x EVO last year with my first ever gaming rig and never experienced such issues. Also with the ram are you installing it correctly?
slot 1_1 they have to be paired up i think that was how the m5a99x was i cant remember from the top of my head
slot 2_1
slot 1_2
slot 2_2

I thought it could have possibly been a bad sensor on either the MoBo or the CPU but apparently quite a few people have had this happen (reading through other forums). As for the ram I believe so? Just installed my new Vengeance ram in
DIMM A_2
DIMM B_2
Which seems to be working fine, did have to set the speeds manually to 1600MHz but looks alright now. Any way of checking this with software?

should it be dimm a_1 and a_2 (rams are recommended being installed together like this) as the board is:
a_1 b_1 a_2 b_2?

Also unfortunately i do not think you can, unless you try a BIOS upgrade via the asus website and hopefully that may adrress any issues you are having. worth a try

Sadly I can't Use the A_1 dimm slot due to my CPU cooler and the ram not being low profile, so I've had to opt for B_1 and B_2 slots, do you think this will make any difference to performance?

I'm not sure if there's much else I can do other than getting a new low profile cooler or maybe even a CPU water cooler

Not sure about performance but It is recommended by RAM manufacturers and made in that way so yeah it's best to follow up on that and use it the way it has been made to prevent any issues. Id your using b_1 and b_2 that is totally fine you don't need to get yourself a low profile cooler just to move ram from B to A (no difference in that) as long as your using number 1 and number 2 of the same letter. which in your case is B which are coloured either black and blue.
As far as the sensor reading are concerned I really dont know, Maybe replug in your fan controller and hope for the best, if that does not work then the sensor is most likely at fault.
