Thought I smelled burning...

post #1 of 8
Thread Starter 
...but everything seems to be ok. I have been tweaking some small OC settings in the BIOS of my sig rig. I've read that I really shouldn't OC on this board because the MOSFETs in it are weak. I have been wondering if maybe just raising the NB frequency and dropping RAM timings without raising voltages could harm my board at all. I was under the impression that the MOSFETs burn out because the excess power being drawn, so does a small OC without voltage changes draw more power or not?

Anyway, I shut the computer down for around ten minutes before I changed back all of the BIOS settings. I don't think anything was actually burning, as I don't smell anything now. Maybe this board just has me paranoid with all of the MSI horror stories I've read.

OC with the addition of voltage will still draw more power than a standard clock, just not as much. thats being said ur CPU isnt exactly high wattage compared to others so I dont think its much of an issue.

In this thread, it's one of the MOSFETs not under the heatsink that burned up and from a six core CPU. Would putting some of these on the uncovered ones help, as a just in case measure?

I'd say just stick your settings back to stock, and if you really want to overclock grab a motherboard with a 8+2 Phase Power Design. I couldn't see any information on MSI's site about your motherboards power design, do you have any idea whether its 4+1 phase or higher?

It's 4+2 phase
post #6 of 8
Often the gets under the heatsink fry on msi boards; it's due to over current with no protection and improper driver size
To avoid permanent damage I recommend no oc and revert to te stock cooler immediately.

okay, therefore you should definitely not overclock it at all. It may say it supports 140W cpu's, but I guarantee you that the next time you smell that burn when your CPU is overclocked your entire system's life could end. Of course it isn't your fault, it's MSI's, but I still recommend a Motherboard with 8+2 phase as soon as possible.

I'm pretty broke currently, so it will be at least a few months before I get a new board. If nothing newer hasn't replaced it by then, I've been eying this motherboard.

Going back to my original question, will I still be putting my motherboard in danger if I OC without increasing any voltages? I can have 2400 MHz stable on the NB at stock voltage, but I'm not sure if that is still stressing it.

I didn't replace the stock cooler on the board. I just meant what if I bought some of these:

And stuck them here:

And leave the stock heatsink on. That's not my motherboard, by the way.
