try lowering ram speed to 1300mhz and loosen timings. I like to find core stable with ram at 1300mhz and loose timings 11-11-11-26-2.

Then add digital i/o.100v analog i/o. 100mv amd System agent.150v as needed when trying to raise ram back up.

Aside from droping cache its the next best way to lower vcore maybe .020v.

Thats only if its clocked so high the imc is struggling.

That's a lot, I'm running -145mV for 2400C9 with 4 4GB sticks tongue.gif

Here is what i can achive with fine tuning the cpu.



I have a problem i did not find in any other of these cpu: i can reach 5GHz easily, watercooled and fully stable (now i'm at these settings runnig XTU) and i can step up to 5.1 or 5.2 under 1.55V but the problem is 5.3!! 5.3 is stable @1.7, no matter what i do. Maybe I'm missing something, strange CPU btw.

What did that chip do to you in order to deserve that kind of torture? biggrin.gif

What torture? XTU? I use it to see if it is really fully stable, but I'm very disappointed... I wanted a 5.3-5.4GHz chip :-(((

The search continues!

I'm talking 1.7V under water tongue.gif

Hahahahahaha, yes totally, sucide OC but you see: these pentiums really like high voltages, i cannot stress test with 1.7V but only look at the freq I can reach. This is a good daily chip, not a good OC chip but maybe under LN2... well for sure this is a candidate!

One thing for certain: I do not want to burn this one too... it is tooooo sweeet!

Im not running any adjustments at system agent, digital i/o or analog on my pentium.

He was asking what else was there to tweak to try and lower vcore and those are the only knobs left to turn that I could think of.

My z87 plus does fine with all of those settings left alone (auto).


My m6h on the other hand requires me to manually raise system agent to get my 4790k 4.7ghz profile stable at the same vcore the z87 plus had with memory at 2400mhz.

These different boards make adjustments differently.

This actually enabled me to drop VCore. Seems some of these pentiums are programmed to a default 1.000V SA. I reach stability at around 0.85V (that's where most are at default).

Here's the Haswell oc guide I used in the past:

FYI smile.gif.



New board arrived and I'll start playing around with it.
