Core i5 power = 112W

[gurusan]

Any links to any programs, I'd be interested see my usage - DFI X38

Everest. However IIRC DFI boards have digital PWM for the CPU so I'm not sure it will show the power draw. My X48 Rampage has a digital PWM and doesn't show.

I would say that its turbo going over the TDP, and also, have you see now much power i5's draw at heavy overclock?!

Yep it's definitely the effect of Turbo mode. No matter what speed the core I5/I7 is, the TDP will always be 95w and if Turbo mode is on, it will go up to 112w. I wouldn't port attention to it because actual power consumption will be totally different.

Ah oh well, I have Everest and it doesn't show it.

They are still the "numbers you should be looking for".

In fact I should in theory be using MORE power as I have HT.

Your program is wrong, mine is in the right ballpark.

I said nothing about how correct the program I was using was as I'd downloaded it minutes before. Yours is equally wrong.

130watts is your TDP it is certainly not showing that if 80watts is what it pulls out and waves on load.

tdp for the i7 920 is 130watts is it not?

Yeah, not sure why I have 125 connected with it in my mind. Fixed.

it wasnt in reference to your post, sorry i should have quoted lol. its in reference to concord rules's

if it's closer to 130watts then concord rules is wrong

When working my CPU (Prime95, etc), my CPU shows up as 112 watts in HWMonitor. I thought the maximum power was 95 w?

I seem to remember it used to show 95 stable, but now it just hops up to 112.xx watts

The TDP is 95 watts. Thats the Thermal Design Power or the number of watts that the cooling system is required to disipate.

The actual current drawn will always be higher.

Forget HWMonitor. The only way to find out how much power is being drawn is to put on a power meter. The cheap ones that fit between the plug and mains socket are pretty good. You can then look at the total power of the system drawn.

Yes, and so is the 2.83 and 3.2 versions. Somehow I think they draw more.

Also mines a lower voltage Xeon...

And as people said before TDP does not equal actual power draw.

90W is what i hit today and thats within in the right ballpark.

After some rummaging as to what apple stuffs their mac pros with...

The chip you're using is a server/workstation one and isn't called an i7 at all. It's a Nehalem based Xeon which sounds like a i7 920 but costs as much as a i7 975.

It's the Gainestown chip X5550 and has a TDP of 95 watts.

Bloomfield is the Nehalem desktop chip under i7 and ALL have a TDP of 130 watts hence the confusion.

Thats the chip I have in my mac pro. Its the ECC enabled version of the 920.
