ASRock FM2A75 Pro4-M shutting down trouble shoot questions

post #1 of 6
Thread Starter 
So, I am putting together a little HTPC/Everyday Use PC for my parents and I had the PSU, RAM, CPU and MoBo all hooked up outside the case to run a start test before I strapped everything into the case and it booted fine, right to the BIOS, and then after about 15-30 seconds after bringing up the BIOS the whole system just shuts down. Here is what I did to trouble shoot;

Checked for shorts, metal touching anything on the MoBo, and had it sitting on cardboard outside of the case, the 24pin connection was not coming apart from what I could see

Tried my back up working PSU (Antec Earthwatts 650W), same problem occurred.

Plugged in the PWM heat sink fan, same problem occurred.

Then I noticed that the CPU was running right up to about 50C, I am thinking mainly because the Heat Sink was not installed, so I switched the CPU Temp Monitor Auto Shut Down off and rebooted, still the same shut down problem. I did not want to get the heat sink all hooked up only to waste time and thermal paste to remove it shortly after.

Also, the HDD and Blu-Ray were not hooked up, since there was no OS installed and this was just a boot test. The MoBo recognized all the CPU and RAM at the correct speeds and names right away, if that helps.

After all this trouble shooting and perusing the forums I have just decided to post my problem. I told my parents to RMA the MoBo because that is what I think is the problem, but any other insight, or confirmation, would be greatly appreciated as soon as possible. Thanks!

System Specs:
AMD A6-5400K
ASRock FM2A75 Pro4-M AMD A75
PC Power and Cooling Silencer Mk II Series 400W Modular
G.Skill Ripjaws X Series 8GB (2x4GB) 1600mhz
(this is just the list of parts that were installed during the problem)

P.S. I know its a little overkill, but they had a good sized budget and I wanted it to be a little beast that they will be happy with for years to come.

Thanks again!

That is weird. I have the ATX version and I haven't had any problems so far with it.

Temps look a bit too high for what it should. Have you make sure that the heatsink is seated properly?

Heat sink was not on since I was just testing everything. Then yesterday I tried it with heat sink and same problem plus now I get no video. Sending the mobo back still. Hopefully the next one works.

I just had the same problem with the Asrock FM2A75 Pro4 (an almost identical board)

It was the memory.

Kingston 1333 Mhz (9,9,9,24 timing) seems to have fixed it.

The crashing memory was Corsair 1600Mhz which also has 9,9.9,24 timing.
It seems to be faulty memory as even the BIOS screen was corrupted (blue and green lines up and down the monitor before locking up).

Since the memory change it doesn't seem to have crashed even once due to memory.

Apparently a lot of AMD systems are quite sensitive to memory.

Both my computers are very sensitive to memory (Asus M5A88V-EVO)... and both have integrated graphics... which is probably what is doing the crashing (lines up and down the screen before crashing).

ASUS went through a lot of iterations of the BIOS to stabilise the motherboard... so the problem probably lies at least partially with the way the hardware works... not just the memory.

The previous Asrock board also had integrated graphics and ran 2000Mhz OC DDR3 quite happily... but the current Asus didn't like it so had to change memory (from a less common brand) to Kingston Hyper DDR.

The Asus still crashes on boot from time to time (Kingston memory seems to need to warm up?).

That's really annoying as the FM2 supports up to 2600 OC memory... and because it runs integrated graphics the faster the memory... the faster the graphics will work. Thus the computer graphics are currently running at half theoretical speed.

Who's to blame? Memory manufacturers or the motherboard manufacturers?

Currently moved the faster Kingston (1800?) to the FM2 where it seems to be running very happily... and the slower 1333 to the Asus bulldozer system... which also seems to be running happily.

If both boards remain stable over the next few weeks I'll consider the problem solved.

FM2 gives very good Windows experience results with the faster Kingston so it seems to be a win win all around.

I'll look around for some faster DDR3 in my spare time... but it looks like really fast 2600 OC memory is rare and VERY expensive.

In the end it played up again so bought some 1333 Mhz Kingston (2 x 1 GB).
It has one stick in the 1st and 3rd socket.

Even the 1333 Mhz occasionally causes it to lock up on boot (blank screen no BIOS post).

Reboot the system a few times usually works

Today rebooting a few times didn't work but disconnecting the Bluray worked.
NB. Disconnecting the HD didn't work.

It was showing Code 10 on the motherboard... which according to the online documentation is a memory problem.

Might have to try removing one of the memory sticks next time?

:-)
