CPU throttle when overclocking? - Page 2

Funny that you mentioned the Zalman 7700cu. I owned the 7700Alcu and was having some really high temp readings (load went as high as 68 degrees). I then purchased the AC Freezer 7 Pro and my load temps wouldn't go past 44 degrees. Read this link for my info

Well, I decided to give the Zalman a second chance, but this time around I lapped it. Now I'm getting readings of 35 Degrees idle and 50 Degrees load.

I'm not saying that you should or shouldn't get the cooler (the all copper version should cool better too), but I thought I should give you my personal testimony first.

my 550 doesn't even throttle at 75C (highest it ever went) and it IS enabled..

Sounds to me like your board has a poor temp monitor and as such its reading temps to low in windows programs. If throttle watch is showing the CPU throttle then you can believe the CPU is overheating, also when the CPU throttles it doesnt change the multi or lower the FSB it slows down the chip internally and the only way you know it is by watching throttle watch and notice a big drop in performance in games and benchmarks or any calculating program. Drop the overclock untill it stops throttleing or just return it to stock, there is absolutely no point in running a Overclocked chip when it throttles because all the increase in speed is lost due to temps.

I don't think my cpu temp sensor is bad.. I think I might have a bad RMA cpu. Intel sent me back a RMA cpu in a new box but when I open the package I can tell the cpu is not brand new cause there were scratch marks from heatsink. Anyways, I was told I was suppose to get a brand new cpu..

My cpu is not overclock anymore and if I run 2 prime95 together, throttlewatch still shows it is throttling and speedfan says the temp is 62c.

When I touch the heatsink, it is barely warm at full load .. this is driving me crazy.

Might be dumb, but what is throttling?

runs at a slower speed to lower the heat to cool down the cpu.

hmm i think i might have found my problem.. the zalman i was using may not be connected properly even thought it dam tight.. i installed my oem intel cooler and at stock spec, it is at max load at 65c and no throttling..

if my zalman was not on properly why the hell would the cpu temp reading be so low err..

might go and pick up the artic freezer 7 tomorrow.

hmm ok nevermind, i overclock the cpu and it is again throttling at 62c... seems like when I overclock it knows and it will throttle even if the temp is still ok. mb temp is 29c so my case is not hot at all..

seems like it only throttle for me when I run prime95.. i ran 3DMark05 and it ran fine with out throttle and temp is at 65c..

throttlewatch log
Average load63%
Average throttling0%

Can it be that my cpu can't take full load?? and it is not the temp issue? can this be a defective cpu again?

Was the box sealed? Intel tests a certain amount of the chips from every batch to make sure they work at the settings intended. It is possible that you simply got a chip that was pulled for internal testing before shipping.


I would definatly recomend a better heatsink and maybe look at your case airflow as well, be sure you have enough fresh air going in and good exhuast to pull the hot stuff back out.
