Quick question about Temperature and Vcore

[Taxus]

When overclocking, the CPU Temperature only increases with frequency, right?

Example: if i use 166 * 12x will iget the same temperature as using 200 * 10x?

The same thing aplies to vcore, ill need the same voltage to 200x10 and 166x12, right?

Tkx in advance

temperature only really increases with voltage, but yes the temps should be the same with a higher fsb to get the same freq as using a lower fsb - assuming same voltages

200 X 10 will run hotter than than 166 X 12.

Closest data I have is from notes for an XP2500+ in sig system:
210 X 11 = 2310MHz, 1.875Vcore to stabilize CPU, 40C idle, 45C load.
215 X 10.5 = 2257MHz, 1.975Vcore to stabilize CPU, 43C idle, 50C load.

Hope this helps!

its because of your vcore not the fsb. you whent up .1v

Excuse me. I didn't know we were just pretending.

In the real world, Vcore often has to be increased when the CPU is doing more work.

Memory bandwidth obviously increases when FSB/memory frequency is increased from 166MHz to 200MHz. That bandwidth increase is not 'free'. The CPU (and Northbridge) have to work harder.

eh?

it all depends on the chip, not all chips need extra voltage to get to a higher fsb.

more voltage = higher temperature

its as simple as that, i really don't see what you're getting pissy about with jsw

to put it simply and to end all disputes: there are way more variables than those you listed. First and foremost it depends on the chip itself. Some need no extra vcore to oc and shoud not get much if any hotter. However if you get a chip that needs extra vcore to run stable at an oc then it will get hotter.

isnt that what i just said?
