Same problem, replacement board!

Ok, so I posted about a month ago about the problems I had with a rather light OC of my new 1055t. The short short version: I used the Easy OC 10% switch on the mobo (MSI 880GMA-E45) and it just crashed after about 1/2 hour of Prime 95. Would not post. Ended up RMA'ing the mobo and CPU.

So this time i did some reading up on OC'ing and decided to do it through the BIOS. Set it up to 230*14, lowered multiplier on CPU-NB to keep it under 2000 MHz. No problems on stress testing (Prime95 for ~1 hour). Max temp ~33C.

Next I tried 240*14 for 3360 MHz. Prime95 again with HWMonitor, CoreTemp, and CPU-Z up. Max temp reached 38C, 1.41V. After about half an hour, poof! Just shut off. Will not reboot, will not post, nothing!

This is driving me nuts! Did I just buy a junk mobo? Or am I doing something else wrong? Here is the gist of my setup:

Phenom II X6 1055T
MSI 880GMA-E45
Cooler Master Hyper212+
Mushkin Enhanced Silverline 4GB DDR3 1600
Rosewill Green Series RG630-S12 630W 80+ Certified PSU
No Graphics Card
2*1TB Spinpoint F3's in RAID 1

The worst part is, my 30 day RMA at Newegg is up now. So all I can do is get another junk board from MSI? I really don't want this POS anymore!

Have you tried resetting the BIOS.

Work through our standard checklist and troubleshooting thread:
http://www.tomshardware.com/forum/261145-31-read-postin...
I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

If not, continue.

I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different.

Breadboard - that will help isolate any kind of case problem you might have.
http://www.tomshardware.com/forum/262730-31-breadboardi...

Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

Make sure you plug the CPU power cable in. The system will not boot without it.

I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

If no beeps:
Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

Silence or long single beeps indicate a problem with the memory.

Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.

That's just it, this is the second time it's done this exact same thing. Don't think it's worth my time to go through all of the troubleshooting again if it is the same problem and it didn't work for the first dead mobo!

Yes, no difference.

The first time I had this problem about a month ago, I cleared the BIOS, breadboarded it with just PSU, CPU, & HSF w/mobo and it would not post. The only way anything would turn on is if I unplugged the 4 pin CPU power. Then the fans and LED's would come on. Now I have a board that even if I do return to MSI, I'll just get another one which I can't O/C! Should have done my homework!

Try removeing the CMOS batt. for 30 seconds reinstall and boot.
See if that works.

I dont know other than its an MSI board.
I have only owned 1 MSI motherboard and I absolutely hated it, it was about worthless.
The only thing I can say is either RMA through MSI or buy something else, but if you have had enough of the MSI board I would judt get something else.
The only other thing I could think of that it might be is the PSU.

Took your advice. Bit the bullet and bought another mobo, this time a Gigabyte GA880GA-UD3H. Working great! Currently OC'd to 3.7GHz w no vcore increase.

MSI is evil!

Great I am glad you got a good board, I have always loved Gigabyte.
Good luck and enjoy the new board.
Thanks for the BA!
