870A G54 (I did something stupid)

post #1 of 5
Thread Starter 
Long time lurk, first time post.

So today I did a combination of very stupid things all of which I will list, but long story short I cleared CMOS when all was said and done and now I have no POST, nor do I have a speaker to tell me what the problem is (but from reading around, when this board gives up very often will it give no beeps at all.)

So first off is CPU, I have a PII X4 965, I've read the stories of 4.2ghz on stock HSF so I tried to get at least 3.9 or 4GHZ OC. So on this particular occasion I put the CPU Core Voltage to 1.467 multiplier to x21 and CPU-NB at 1.282 @ 2.4Ghz, shouldn't be that bad worse that'll happen is OC will fail, and ill just rule that out as a possibility and aim lower.(or so I thought.)

Next is memory, when I first built my PC I was on a very tight budget so I opted for a single 1GB DIMM of ADATA DDR3 1600, it always ran well with the 1:4 to 1600, until I picked up 2gB 1333 intel xmp dimm. It plays very nicely with the ADATA RAM in dual channel 1333 9-9-9-24. But I thought "hey if I match the XMP timing it can reach 1600 with 1.65v. So after many failed attempts and BSOD with BCCode a, today I thought I would try 8-9-9-24, 1333 (I had tried this config before and it just resulted is the "a" BSOD, but i thought maybe the CPU-NB OC, would make a difference. So I set it up so and put the DRAM V to 1.63 (This board has coarse Voltage selection :/ )

Lastly I gave the SB NB and HTT All a boost into the highest safe range as specified by MSI.

saved, and hoped for the best.

Well I got far less than the best. Twhis board has an OC retry max times option, and I set it to the lowest. But more often than not i have to clear the cmos, or move a stick of RAM to get it out of it's destructive cycle.

Well this time I restarted it twice after no POST and the third time I could have sworn I got a whiff of burning plastic from my antec 902's big boy exhaust, if only for a second. I shut it down and tried clearing the cmos. Battery removal, jumper, nothing seems to be working.

I had an extra stick of RAM lying around and I tried using it but it still wont POST, so I've ruled out RAM.


I could care less about the board, since I got it, it's had audio static and the usb ports are quite literally insane often, and it wouldnt boot with my 9500gt and an x4 pci tv tuner at the same time. My only worry is that i've fried the processor but based on the actions I took how likely is it the CPU as opposed to Mobo?

If this provides any info (Idk if it does but I thought it was noteworthy) it will start via power button, but wont shut off via Power Button.

Oh and almost forgot, if it is indeed the motherboard, should I go for

Sabertooth 990FX
GIGABYTE GA-990FXA-UD5

I'm actually trying to save some money so Crosshair is out of question, so if someone could recommend me a good future proof AM3+ board that has x16 X2 CF as I plan on getting 2 radeon 6870s down the road that would be great.

Hey mate, welcome to OCN. Too bad this happened though... The thing is the 4.2GHz OCs you may have read about certainly weren't on a 4phase VRM MSI board. In fact here are tenths of threads about burnt MSI boards with only 4 phase voltage regulation (VRM) that are barely enough to run 125W processors at stock speed; OCing should be completely overruled on them unless the user is an expert - one has to tune each and every parameter by hand, test and follow VRM temps.

So considering these things:
*your motherboard's design
*the setting you used - not exaggerated for a decent board, though I'd never OC the way you did - best results come when you start slowly
*the hiss, burnt smell and that it came from the PSU area
...likely the board's VRM are fried, so dead motherboard. Less likely is that when it broke down the board may have send a voltage spike to the CPU and toasting it too; in the majority of cases the CPU is fine.

Two more things - first all Phenom II x4 have a very hard time going over 3.8GHz; 4.2 GHz is an extremely best case scenario. Also anything over 3.2GHz and 1.35V on stock cooling is asking for trouble, if the mobo didn't burn out the CPU might have @4.2 and 1.45V - this is water cooling territory. Sencond thing is that unless you want to crossfire 2x 6990 you don't need 2x PCIe x16 - not now and not in a few years. There's no point in paying 100$ more on the motherboard for that, better divide that 100 by 2, add that to each 6870 cost and just get 2x6950 1GB on a 2x PCIex8 board, it would be much faster.

Bottom line - OC slowly and don't put much emphasis on PCIe x16.

*EDIT: got carried away with this post, slow morning @work

Well apparently it was just my luck then that you had a slow morning!

Big thanks on your post, I never quite knew about the VRM component of motherboards and what the whole 4+1 phase thing exactly did. Luckily though I read up on it and now I have a good idea of the next board I'm aiming for, Kind of makes me feel like I was duped into buying a bum board on msi's part though considered the way it was advertised.
Luckily though there appears to be plenty of 8+2 boards from asus and gigabyte with x16 x8 cf within my price range.

Even though I won't be heading for fx, I still wanted to keep my options open and go for am3+. Even though zambezi doesn't exactly match the criteria I'm looking for hopefully the platform achieves something great next year in am3+.

If the VRMs totally fried it would not boot at all...

What if just a mosfet or capacitor went out? Maybe it can no longer handle the tdp of the processor even after cmos reset (stock) clocks?

Also I searched all over the internet, there are cases floating around where their pc not only won't post, but the power button stops working to shut off their pcs as well. None of them ever post back with what it was though.

If anyone has a definitive idea of what not posting and not shutting off via power button hold down it would be a godsend at this point.

Edit: http://forum-en.msi.com/index.php?topic=143018

This guy on the msi forums had the same symptoms, and it turned it was the mobo so I guess that's where I should be placing my bets.
