2600k+Z68XP-UD3P Crazy Voltage issue!

post #1 of 7
Thread Starter 
So I built a somewhat new rig out of some left over parts and some I got used and I must say this 2600k has given me way more problems than my old 2500k did.

Multiplier - 4.6
Vcore - 1.36
Vtt - 1.7

Everything disabled that supposed to be.

RAM rated at 2133 set to 1600 for OC purposes.

Here's the catch..

Vcore is manually set in the BIOs at 1.365, it will boot in windows etc and everything is all fine and dandy but when I start testing stability my vcore will drop down to 1.31 and stay there while I'm stressing my CPU to 100%. Then when idle it'll jump back up to 1.365 and as soon as I do anything it shoots back down to 1.31-1.32.

Shouldn't that be the complete OPPOSITE? Like, ***?

Anyone feel free to shed some light on this, if you can +rep for the help. Would really like to get something going so I can get down on the Beta lol.

Thanks OCN!

Why run ram at 1600 when you can do 2133?

and what are your temps when your running 100%

That is not the question at hand. Please stay on topic and just stick to the question at hand.

Would really hate the bug a mod to clean up a thread due to off-topic questions.

I believe you're experiencing VDROOP which is normal. You can lessen the vDroop if you enable LCC (load line calibration) and it will depends on how much LCC you use. For example in my MIVE I have 75% LCC and I get minimal vdroop with load but if I put it on EXTREME LCC, my voltage actually goes higher (on load) than how I configured it in BIOS. LCC compensates on the voltage loss

Usually any LLC level for me SHOOT my vcore threw the roof.

Which scares me a bit, but I guess I can give it a shot, thanks.

Should have thought about that before I made this thread, kind of obvious in a way lol.

Thanks man!

While I haven't used a 2600K on that board, I just built a 2500K setup for a buddy, using the Z68XP-UD3.

To get rid of v-droop, I'm using LLC on Level 6, which raises the Vcore by 0.03V under load. I'm using 1.360 in bios, and EasyTune6 shows 1.392V idle, and 1.426 fully loaded.

What do you consider "through the roof"? For myself, I'd feel perfectly safe about .03V. I think where people get into trouble is using 1.5+V during suicide runs, and running LLC on Level 10!

But on the other hand, it may be a good idea to set a really low Vcore, like 1.300, and using LLC 10. That way, you'd get a nice cool idle, and stable overclock. I'll have to try this out when I build my own SB system (if AMD messes up again on Oct 12).

I did LLC Level 6 last night and finally got it stable.

Anything higher than level 6 and my vcore will shoot up from say 1.3 to 1.49 at a random given time.

Level 6 did the trick for me though, so I can't say I have anymore room to complain..
