CPU Throttling

by Frop • 26 Oct 2007, 19:53 • Journals
Mate of mine bought a ASUS P5K and Intel Core 2 Duo E6850, however when we run the System Stability Test in Everest we get 100% CPU throttling. :x

I've already let him update both the Intel chipset drivers and his BIOS, but the problem persists. The CPU also reports temperatures of over 80 degrees at full load even tho it's around 30 degrees when idle (it jumps to 80 degrees within a second, looks like a faulty readout).

If anyone knows how to fix this I'd appreciate any help...

Check weither the motherboard and chipset support the processor

Also it might be overclocked by default

P5K is one of the newer ASUS boards and definitely supports the CPU.

Well if the reading is incorrect you will have to wait until and update of bios/chipset

You are a nuisance indeed.

mmm, might sound stupid but: applied the thermal paste? (i have a "secret" recipie if you wan't it, just give me a pm)

It was supplied stock with thermal paste and like I said, I doubt the temperature readout is correct at the moment.

Check if the cpu fan attached correctly, check if the thermal cream
is there and spread correctly.

It is, but even then that has probably nothing do with the throttling issue.

It is if the temperature is too high everest will report thottling

Check if he setup the bios properly, if the cpu clock, voltage and everything else is fine.

I've intentionally set most of the BIOS options to automatic... it might not have given him the best performance, but it should have been stable.

Check the cpu on other motherboard and see if it's working there, if not send it back to intel :P

if it is, send the mobo back :P

uuh.. idk if everest reads directly from the CPU or from the thingy/sensor thats on your board
try core temp..

wow this shit is too long ago:( and idk if this program reads from the cpu directly

Intel and AMD recently published detailed, public information about the "DTS" (Digital Thermal Sensor), which provides much higher accuracy and more relevant temperature reading than the standard thermal diode sensors do.

I'm expecting that it's some BIOS issue indeed, but the throttling is way more annoying.

I take it th 80 degrees are coming from the BIOS itself and not the monitor software that comes with the motherboard? Also, when you flashed the BIOS, was it the latest version? Sometimes issues like that can happen with the latest versions of a BIOS. Try getting an older one if you can, it's helped me in the past at least.

One last thing I can think of, with the new Intel CPU's, they have those dodgy heat sink attachments, that require you to push them through the board. Make sure once all four are through the board that you turn them to lock them, otherwise, you will get silly temperatures on your CPU.

Those are just things off the top of my head, hope one might help.

We had the same issues with the stock and newest BIOS, so that wasn't it.

On the other hand your heat sink attachment tip was gold! It indeed turned out you have to apply even more force than I expected, they are quite retarded indeed. He's running at a nice 35 degrees now under full load without any throttling. :)

Yea, I've had that a lot recently. One of my jobs at the moment is in a PC repair shop. Loads of people come in with the Intel standard heat sink for a dual core, complaining that once they start their system up, 2-5 minutes later the PC just switches itself off. No event log, no blue screen, nothing.

Almost all of those where because they hadn't attached the heat sink properly, so it wasn't making a decent contact with the top of the chip. They are retarded though, you have to really shove them through to get a decent connection and even then, most people don't lock them (from my experience). Plus, people are nervous building their own systems, so using that force doesn't really happen, unless you are working on someone else's machine.

Glad I could help your friend though. :)
