Voltage woes on a Z68.

post #1 of 4
Thread Starter 
I don't overclock much at home...After a day of blowing up things in the office, OCing custom builds etc...I just didn't feel the need, until Monday, that is.

Setup is in my signature...The first one, second build is my PCOIP//work PC.

On Monday, a divine presence urged me to OC my 2700k at home to 4.5ghz and...I was bored so, I did.

Primed it for 36 hours (I worked overtime that night so, didn't get home until 36 hours and change)...0 errors...Also IBT'd it about 100 times solid, no issues what-so-ever.

My sound card occasionally has a senior moment and locks up the entire PC, about 1x every 2 weeks but, that's something I choose to put up with because the Fatal1ty has a bangin sound.

Anyway, I'm getting 3 different voltage readings...And while my loop is heavy duty and can dissipate FAR more wattage than this PC (Used to be a 990x with full cover + ram, etc...) it's very...odd.

I've never encountered this issue and our Intel tech conveniently took a 2 week vacation to Peru...Lucky bastard.

I have it set in the bios at 1.26...Which, from experience is a little high but, I haven't had time to play with it...I can see it running fine at 1.22 but, like I said, just haven't had time.

Anyway:

Eleet has the core at 1.36
Bios has the core at 1.26
CPU-Z has the core at 1.3
AIDA has the core at 1.28

If I attempt to edit the voltages in Eleet, the whole thing goes wonky...I.E. it gets really slow and I have to force re-start or else it's just really unusable.

I've had 0 BSOD's and 0 lock-ups due to the core...0 issues in any ram test and/or anything else really.

Now, I can run 1.36, it genuinely isn't going to effect the longevity of the core or cause any degradation because on load it's max 38-40c but, that's still too high for my tastes if that's an accurate depiction of the CPU's V.

Any ideas?

1.26v is not too high. You yourself have hammered me for complaining about 1.385 for 4.8 GHz. My chip needs 1.285 with ultra high LLC to be Prime Blend stable for 12 hours at 4.5 GHz. The second chip I bought needs 1.290 for 4.5. Regardless, I would go with what CPU-Z tells you. Are you using auto, manual, or offset voltage? When you say BIOS shows 1.26, do you mean that you've set it to that or that is what BIOS is showing the current voltage as? Do you have any LLC going on? If you have manual voltage set to 1.26 in BIOS, the highest level of LLC could push it up over 1.30 at load and that's what CPU-Z could be showing you.

As I said, I'm not worried about it...It's just an oddity...I know it can go lower considering it's batch but, I was waiting to get some opinions before I even tried.

Seeing 3 different voltages, halted my efforts to go lower...

It's set on Manual to 1.26, Ram is at 1.45...Everything else is normal.

Load line = Vdroop and it's disabled, however.

Very odd then if Vdroop is disabled. You should be seeing way lower volts under load then, probably under 1.2 in CPU-Z with prime 95 blend. What about spread spectrum? Disabled or Enabled. There's a lot of chatter on the Sandy Stable Thread about spread spectrum giving some better results while huring others. Maybe switch it from whatever it's at and see what happens. Also, ditch ELEET for the time being to make sure this isn't a software problem. After that, maybe enable a low level of Vdroop to see which direction your voltage moves, just in case.
