How does BCKL affect temperatures?

post #1 of 12
Thread Starter 
I've got a stable system running at 4GHz@1.304v and those 1.304v is kind of high imho.

Will increasing the BCKL affect temperatures or is it Only the vcore that makes temp go up and down?

usually vcore, cpu ppl, qpi/vtt will increase temps (anything on the cpu with requires voltage and which are raised.

OK, so increasing the BCKL / Uncore Ratio / Mutliplier / Memory Ratio will Not increase temperatures?

just voltages, but in order to get faster bclk you usually need more voltage, so i guess in that sense, lol

Short Answer:

Bclk increases the Frequency of everything(given constant multipliers) and that will increase temps across the board.

However, increasing frequency is not going to cause temps to rise near as fast a voltage will...


Think of it this way when something moves faster it has more energy, heat basically is a measure of energy.

it doesnt do anything unless it also increases CPU frequency.

191x21 and 200x20 should be around the same voltage, which means same temps

yes it will, but not really noticable like 1*c with every 50 BCLK because the cpu is still getting faster

If you are lowering the cpu multiplier and upping the BCLK to keep the same CPU clock speed then no. For example if you are using 175 BCLK x 24 = 4.2GHz or 200 x 21 BCLK to give 4.2GHz CPU temps will be very similar. You will however increase the temp of your motherboard/memory as that is being put under more stress and may require additional voltage for stable operation.

As said however if you are increasing the BCLK to increase your overclock then yes because you CPU is obviously working harder.
