Is my CPU throttling?

post #1 of 3
Thread Starter 
Hi, I've had a Xeon E3-1230v2 for a little over a week now, and I've decided to run prime95 yesterday and I noticed in CPU-Z the frequency only going up - to only 3.5 and not 3.7 (the max turbo frequency that's advertised).
Does this mean it's throttling? HWmonitor was reading 62 after about 5minutes. I have a Hyper TX3 Evo. Also just browsing the internet temps go from ~35 to 48, very abruptly.
I've applied TIM the "pea" way after having it applied between the heatpipes for 1week+, and I see no difference...

Is this normal? Why is it no going to 3.7, I think Ive only seen it once go to that freq,on the day I purchased it...
Thanks in advance.

probably not thermal throttling. See if power profile in windows is allowing your processor to reach 100% (usually balanced and high performance will)

The maximum turbo multiplier is 37 but for your CPU, this is only available when a single core is active. When all 4 cores are active, the maximum multiplier decreases. It's likely only 35 for your Xeon E3-1230-v2.

This limitation is built into the hardware. A Xeon CPU is not the same as a K series CPU. The K series can be adjusted so you can run the same maximum multiplier whether 1, 2, 3 or 4 cores are active but you can not do this on your Xeon CPU.

Run a single threaded benchmark like the XS Bench in RealTemp and it will accurately show you your maximum 1 core multiplier. It should be close to 37 but there are always background tasks running on any Windows PC. As soon as these tasks need to be processed, additional cores have to become active and that instantly lowers the maximum multiplier. RealTemp reports a very accurate average as this is happening using high performance timers within the CPU and a monitoring method recommended by Intel.

Many non-K CPUs allow limited overclocking by up to +4 bins above the default maximum multiplier but I am pretty sure this feature is turned off inside your Xeon CPU.
