CPU Water loop work log

I meant the whole rig man. 1.5, 2k?

Looks like you have a lot of gear in there. I'm just curious as to what it's all worth...

yea, id say about $1900... wish i had a i7 and a 5970 tho :/

oh well, next time

idle temp 73*F ambient

load temp running prime95

Some nice temps there. I wonder what kinda temps you'd get if you had an i7 @ 1.5v in that system. Probably a bit higher right?

there's no good reason to have 1.5v going thru a i7.

Ok. So the temps would obviously be out of control then.

 

[Sean W.]

i7s like about 1.35

Yup. That's what I have mine at!

the reason i have my voltage so high is because my hardware is not effiecent, i have a crap mother board and i dont have a C3 stepping processor.

even when i had my H50 radiator in a bucket of ice water, and i was getting 10* idle temp and 25* load temp, i was barley able to boot at 4ghz. so its not temperatures keeping me from going higher, its hardware. i dont belive i ahve a C3 stepping CPU and i have the last gen chip set on my mobo. i did flash the mother board with the newest bios when i reinstalled windows and that didnt help at all.

its hardware, not temps keeping me from going higher

I got my 940 to 4.16GHz in a Gigabyte MA790X-UD4P.

I think it's more likely the board - nothing to do with the chipset, mind you. It's the power regulation. This board does have a vdroop of about 0.03-0.04V in my case.
So when setting the core volts, you need to set them by about that much higher than your target.

But then the board also does have a limit of 1.7V in BIOS (which results in about 1.66V) if you're pushing your CPU to the very limits.

Some nice temps there. I wonder what kinda temps you'd get if you had an i7 @ 1.5v in that system. Probably a bit higher right?

You wouldn't want an i7 running at 1.5V, at least unless you're prepared for the possibility of killing the board/chip.

With an i7 and Phenom II chip with equal power consumption, the Phenom II uses higher volts.
