CPU multiplier and FSB messed up

post #1 of 29
Thread Starter 
I already enabled 4 core without any crash and I set the CPU ratio to 16.5 and the FSB frequency to 200, CPU NB-ratio set to x10 (based on default value). AMD Cool n Quit was disable and the rest I let it to auto (voltage,ram etc)

Now, my problem is sometime i turn on my pc, the core speed will change by itself. Here are the result from CPUZ:

803.7MHz (multiplier;4 bus speed; 200.9MHz) try to restart, i get
3315.8MHz (multiplier;16.5 bus speed; 200.9) and sometime I get
3300MHz (multiplier 16.5 bus speed; 200)

And IMO, the performance are decrease when it's 803.7MHz so I didn't think it was software bugs. And AIDA64 Extreme Edition give me the same result. And during OCCT test, run smoothly except GPUmemtest.

Hopefully somebody can explain and help me. My mobo doesn't have a lot function. I'll try to attach a screenshot sooner. TQ

It's 800mhz, the leftover is just ref clock variance. Same with the 3315.8, nothing unusual. When it's at 800mhz, cool and quiet is on meaning it's on power saving mode. Shouldn't have any decreased performance, because it should go back to 3300mhz instantly when you load up an application.

Does the frequency stay at 800mhz even if you run Prime95 or any stress test program?

Wait till this problem recurrent again, i try to run a test. It really random. I think it have connection to voltage setting but I didn't dare to fry my mobo. This is my 2nd mobo in 1 month. Fried up my 1st mobo less than 24 hour when my machine out from store.

It seems that it stay wit 800Mhz even when I'm running OCCT and AIDA stress test. Haven't try Prime95 yet but one thing I notice is my core speed also detected as 800MHz in bios though i already set it to 3300MHz. This thing make me insomnia...

During 800MHz, I notice my core voltage decrease to 1.032V in CPUZ, and my pc suddenly freeze during OCCT, and after restart, back to 3315.8MHz, noted my core voltage are 1.376V while in AIDA, I get 1.4250V, 2 hour playing Alice Madness Returns without crash. Prime95 test 1 hour, no error. AIDA, OCCT, run smooth too.

I try to set the voltage manually, still having the same problem. Am I having PSU issue right now?

Just one respond I guess gonna sell my mobo and cpu *sigh

Same problem here dude, its the mobo overheating -> you need mosfet/VRM area cooling. Since you can't just glue some copper on there (warranty void) best thing you could do is mount a good fan to dissipate heat in that area OR try a Katana 3 cpu cooler since its at a 30 degree angle and its supposed to cool VRM area (not tested though). Let me know if you find a a better solution, right now i'm waiting for my katana3 and also modding my case to fit 2 fans that blow on the MOBO.


edit: some motherboards have holes designed to fit special mosfet cooling kits, mine doesn't but maybe yours does! found this useful thread btw http://www.overclock.net/amd-motherb...t-cooling.html

My FSB is messed up, If I set it to 300, it will always go to 301, or 250, and it will show up at 251..... Really annoying, It's been doing it since Iv'e updated my BIOS with the 3017 AM3+ Bios with a 1055T Chip, Iv'e reverted back to 1902, and it's now a curse.... stuck with it forever!

emdea22: How you know it was mobo overheating? I found out that this problem most of it occur after shutdown. My current solution is to turn on my pc, then have a restart and I will get my suppose to core speed. Inform me if the Katan 3 cpu cooler settled it for you, okay?

Atomfix: So, there is no solution until right now dude? As i told above, my solution is the restart and so on but it's really annoying

I'd ditch that MSI board real fast. No MOSFET cooling = danger when trying to overclock or unlock. Just take a look around here at some of the stories about MSI boards catching fire/exploding.
