e6600 voltages not matching bios settings

post #1 of 5
Thread Starter 
I just got a TR ultra-120 extreme, and I'm trying to get my e6600 to 3.4. Well I did, but as soon as I started a stress test, BSOD. So I set my BIOS voltage to 1.425. Now I can stress it in TAT with no problems (still going to use Orthos later to make sure it's stable). The weird thing though, is that in CPU-Z, it's indicating a steady 1.392v at idle (look at the CPU-Z in the upper-left hand side, sorry about the size):



and a steady 1.360v under load:


despite me setting the voltage to 1.425. So when I go back into BIOS to make sure I set it right, here's what I get:


I haven't changed anything, this is what I saw when I opened the page. How can the "current value" and the "setting" be that different? Is it my PSU or just not an accurate voltage measurement somewhere? Thanks for any help.

Edit: Also, what's the best program/utility to get the best reading on actual core voltage?

believe this is a case of 'voltage droop.' Completey normal but something to keep an eye on.

also, you might get a better overclock if you manually set FSB to 1.5v. Mite even help the droop (tho I have no idea if it will or not). I'd up the SPP too, but that's just me.

ok, thanks for the info. I'll definetly set my FSB, but what's SPP or MCP for that matter? Should I set all my voltages manually?

Also, I've heard to not put more than 1.5v into the core. So should the "setting" or the "current value" not go over 1.5?

Yeah that voltage reading is the vdroop, the setting is what matters. My P5B Deluxe also has a vdroop of 0.055v and if I pass 1.42v the vdroop goes up to 0.3v.

SPP is the north bridge, up that a tad for a bit more stability (not much, if any really). MCP is the south bridge, no need to adjust this.
