The multiplier on my 1090t keeps dropping to x8. Why?

post #1 of 39
Thread Starter 
Running 4.0GHZ at a 20 multiplier, and I noticed when I'm stress testing and such, it will randomly drop to 8. Did I leave some setting I shouldn't have on in the BIOS? wink.gif

Turn off/disable Cool N' Quiet and C1E in BIOS.

I've tried that, however the option for minimum CPU usage (or something along those lines) is not under the advanced options.

I've only seen that option on laptops. So I can't set it to 100% manually.

I had this happening on my old motherboard..... its actually none of the above. Mine was caused by the mossfets on the motherboard overheating. I was able to get some stick on copper heatsynics from newegg that fixed the issue.

I have the ASUS M4A88TD-V EVO/USB3.

I'm assuming you mean these:

mosfets.png

I just added another exhaust fan to the top of my case so it pulls the hot air from my H50 right as it exits the radiator. Hopefully that will cool them better because it was pretty toasty in that area. If not, I'll just pick up some of the heat sinks you mentioned.

(In case you were wondering, this is a friends computer I helped him put together, that's why it doesn't match with my rig in my signature, just saying.)

Nah, those things you circled are the chokes.
To the left of them, under the long blue heatsink are the transistors, or MOSFET's.

If you've got a heatsink on them, you should be fine in general, but it depends on the quality of MOSFET's used by the motherboard manufacturer.
X6 CPU's in particular when OC'd put alot of strain on the MOSFET's, you may have heard about alot of MSI 790FX-GD70 and 890FX-GD70 Motherboards toasting, this was due to people pushing their X6's for a great OC, and even though the MOSFET's had a heatsink on them, the quality of them wasn't enough to hold the power and heat.

AFAIK, that Asus Mobo is very good, and hasn't had any problems with X6's, I'm curious though, what kinda temps were you getting when stress-testing the OC? And at what Voltages?
HardWare Monitor, and CPU-Z screenies when running the tests and getting the CPU to throttle.

I've seen a few of the M-ATX versions of that board to do a similar thing, but they lacked MOSFET cooling, so people put those heatsinks mentioned on them, aswell as a fan directed in that area.

You could also see if there's a BIOS update for that Mobo, that raised the throttle temperature, if it was ever a problem.
But checking the Temps and Voltages would be a first for sure. smile.gif
