[Help]New AMD PC, motherbord problems

post #1 of 14
Thread Starter 
First of all i wanna salute everyone on the forum, as you can see i'm a new memeber. FYI i have red the TOS and used the search function but i couldn't find a specific part of the forum which caters to "Help and support".

Now for the reason of this thread, i have recently bought new parts for a modest gaming computer but after assembling them i encountered 2 main problems:
1. The motherboard(i will get to the spex soon) doesn't always POST
2. The computer freezes randomly even in the BIOS eek.gif and after holding down the power button and restarting the system the mobo doesn't POST so i have to redo the Clear_Cmos routine to get the mobo posting again.

My computer specifications:
1. Motherboard: Asrock M3A770DE
2. CPU: Phenom II x4 955 BE
3. RAM: 2 Gb DDR3 1333Mhz A-DATA, 1 stick
4. GPU: nvidia GTX 560 TI from Gainward
5. HDD: Western Digital 500 Gb Sata II, 32 mb buffer
6. PSU: Seasonic S12II-520W Bronze
7. Asus DVD-RW
8. Chassis: In Win Griffin Black

Things that might have gone wrong:
1. Since this is the first time i build a PC myself i didn't know which way i should install the heatsink fan that came with the CPU (mainly the clamping leaver)so i switched the orientation 3 times wheee.gifaxesmiley.png which could have yielded 2 results:
-the thermal paste got too thin
-i might have damaged the CPU?!
2. The schematics for the connection of HDD_LED, Power_LED, Power_Switch, Restart_Switch are conflicting, the one in the mobo manual shows the connection in 1 way and in the manual for the cassis in another way.Still i got the system running at one time and managed to start installing Windows but the computer froze during installation. My point being that the connections probably aren't an issue.
3. This i am asking, is the motherboard just bad and i need to RMA it? Or there is more to it?

If i posted (pwn intended) in the wrong section please forgive me, i am new on the forum but i have been reading the OCN articles for years, just never got into the community, well until now.

Regards,
P.

Sounds like a memory or CPU stability problem. You may need to crank up the CPU and/or RAM voltage.

agreed, i would check here www.cpu-world.com for the vcore specs for your cpu and go to your ram's manufacture website or look on the ram itself for the voltage ratings for that and make sure your bios is set for those voltages and go from there.

A CPU stability yes, could be and i will try today to reinstall everything and reaply thermal paste and i will check the voltage,for the memory i will check the voltages as well and i will post here the values, but now i'm at work so i will do it later today.

Also when i got the mobo posting i ofc entered the BIOS and the CPU frequency was set to default, 3200 Mhz. What surprised me was that 2 of the voltages displayed in the BIOS keept changing quite rapidly.

Also the rest of the voltages were above spex, for example the 5 Volt was something like 5,123 and so on. Is that acceptable?

When i accesed the BIOS the CPU voltage was something like 1,3V+ i can't remember the exact value, since i only got there 2 times. To get the mobo to post is quite troublesome, i have a dual slot GPU and the Clear_CMOS header is right underneath it, so i have to uninstall the GPU then short pins reinstall GPU.....the mobo doesn't have a VGA or DVI out which would have been wonderfull in my situation.

Also Asrock has included a header to set a stupid imo preset for the mobo called something like EUP, which is supposed to save current....i set this header both on default (1,2 pin) which is EUP on and also the other way arround 2-3 pin but the symptoms of the system were unchanged.

Could the problem be caused by the motherboard not supporting the CPU and RAM? If the BIOS was one of the old versions before the Phenom II x4 955 HDZ955FBGMBOX was released? Same goes for the RAM, i just checked Asrock M3A770DE support list for CPUs and BIOS version 1.20 added support for the 955 Black Edition but not the one with the code i mentioned above. The A-Data ram i have seems to be on the supported list but it might depend on how new the BIOS is.

So question 1:
What is wrong with my CPU code?

It's not even shown in AMD's compare list
http://products.amd.com/en-us/DesktopCPUResult.aspx

Question 2:
What would be the best mobo, at a reasonable price, for my CPU with the specific code i mentioned above?

Your board should work fine,you just might need to update the bios.Check what version bios you have when you boot it.Sometimes you have to change the pin orientation for your cases front panel-just lift the little tab on the side of the connector and push the wire out of the connector.Match them to your motherboards pin-out.Make sure your board is using stand-offs and nothing is shorting on your case.

I speak English and i know a little about pins and wires but i really didn't understand this part. Could you please explain? I'm really desperate, i will try to update the BIOS with the latest version but my fear is that might not solve my problem.

I checked and there is nothing shorting my mobo, i only have 1 stand-off the rest are built-in from the case. I will call the e-tailer tomorrow and ask to send it for repairs if i can't feagure it out by then.

It's flipping impossible to work with it, i only got it to post like 4 or 5 times and i shorted the Clear_Cmos like 30-40 times in 3 days. I'm at the end of my wits.

Can you clarify anything about the serial code? Why isn't it equivalent to anything on the motherbord's manufacturers? I can find in the support list the other Ph II x4 955s but not mine, it's pissing me off.

Edit, i finally found the OPN tray number for HDZ955FBGMBOX, it's actually HDZ955FBK4DGM.

Asrock says it's supported by Bios v1.20....i just tryed to flash v 1.70, the Instant Flash worked perfectly till the very end when it said "Installation complete, press any key to restart". Well i pressed and the PC froze AGAIN. I'm pretty sure the mobo is f***ed up now.

you say you have re-seated your hsf 3 times? and not replaced the TIM? you must replace your TIM every time you remove the heatsink..
no such thing as too thin TIM....
Also,does your board support a 125w proc?

Yes the mobo supports up to 140W CPU
http://www.asrock.com/mb/overview.asp?Model=M3A770DE

And no, i haven't replaced thermal paste since i reset the hsf 3 times but in like 10 minutes, the paste was still soft. I don't have any available now, i'll procure some and some cleaning kit for the paste but it will take a few days.

Also if this is causing the problem why is the CPU freezing even in the BIOS when there is no actual load?

I wouldn't trust it for overclocking... unheatsinked 4+1 (3+1?) phase and it's low quality. You'll have to make do at stock.
It may just be a simply faulty mobo, but check the RAM
