Overclocked 1100t underclocking itself under stress testing....

post #1 of 9
Thread Starter 
Exactly as the title says! I've got a 1100t, overclocked to 4.01GHz 1.45v on the core. Rig specs in the sig! When gaming or any normal task, it runs at overclocked speeds, but when using p95 or intel burn test, it runs at 4ghz for a while then underclocks to 1.7ghz and stays there. Any suggestions to stop this? Does it mean my overclock is unstable?
Thanks for any help, just ask for anymore information if I haven't included it!!

Are there any failures during the prime95 run? (cores dropping off) Have Task manager running and watch the CPU levels (for all cores) under the Performance tab.

Watch test results and look for a "Worker has failed" error during prime95, this is my guess at this point.

Its your motherboard downclocking and undervolting the chip to avoid hardware failure. I solved this problem on one of my Asus boards by laying a 90mm fan on top of the Mosfets. Kept them cool enough not to cause the throttling. Heatsinks are not enough to keep Mosfets cool when stress testing on some boards. Well they may be cool enough, but Asus boards have lots of features that prevent damage, some like this one, are annoying.

Did a run of prime95 last night and no workers failed, but when i woke up it was running at 1.7ghz. I have noticed in CPU-Z that the volts do drop when it goes to 1.7ghz. Do you reccommend a fan over the mosfets then? Anyway i can mount that in my case?

CPU temperatures? Can it be it's throttling itself?

This usually happens on the M4A88 series and 89 series a lot. I did some testing with these motherboards and found this issue, way back when it was launched. After discussions with Asus tech, I finally realised that this was due to throttling. This happens due to high temps of the mosfets/NB/VRM area. Therefore the motherboard kicks in to kind of save itself...I hope this answers your question.

I've mounted 120/80mm fans to the back side of the optical drive bays (with empty drive bay of course) using zip ties for a temporary mount. Than after finding proper position fab up a rigid mount to connect two screws in fan and other end having two screws to mount w/nut + bolt, using extra screws from other builds etc.

I keep the fan just inside the drive bay, but angle it to aim at VRMs only issue depends on which style CPU cooler you have (it may block flow from this location) Newegg has remote fan mounts available also.

Another solution may be to take a top case fan (if your case has one) and have it blow inward into case onto the VRM's. Many solutions, just depends on what you have to work with.

Will any of these "cure" your issue? No, it may/should improve it, but cure it, no. Definitely worth doing to help as much as it can, but only as long as it takes to upgrade the mobo to something designed to handle OCing better.

Till that point you might want to consider reducing the OC a tad and call it good.
