No benching above 1.45v and that was only for a SuperPi 1Mil. Yes, it degraded in my opinion. I'm currently priming 4.6ghz now :down: Makes me want to kill this cpu and get a new one.

All clocks where tested Prime95 8hr blend and small fft stable.

2500k
4.8ghz 1.36v original oc
4.8ghz 1.38v retested 3months later after a blue screen. 1.36v wouldn't do a 8hr Prime95 no more....

I had that problem when I flashed to 1305 from 1204.

Played with some offsets and llc settings. Wonder if this gonna 8hr prime stable also.

First time Asus mobo user here also and probably might use EVGA next if they get around to releasing their boards. Asus just has too many problems.

My new replacement b3 board needs more volts for 8hr prime stable. bah.

Got mine today and Asus sent my a brand new pair of ear phones also! Wow...nice.

I wouldn't be do 1.5 for 5ghz when you can do 4.7-9 for less then 1.4v.

Same for me. Hoping I get 1204 bios in my b3. Not liking 1305.

Wow I thought those C chips were mostly sexy. Too much volts for 5ghz.

I got the same batch and 5ghz needs 1.42v+ for 8hr prime stable. So I stayed at 4.8ghz also.

I do. Please provide info.

lol nice desktop ;) haha i wouldnt show some of the things on there.

okay...i dont like this bios version. i'm constantly booting into windows at 1.42 volts then it goes to my bios inputted 1.38v when stressed. wtf. then randomly jumps to 1.42v when stressing too....

Anyone see a jump in temps with the new 1304 bios? I never hit 80c or high 70s with my 24/7 oc settings and now they do in stress tests.

20 Pass Linx is not 24/7 stable. Thats what I use to narrow down my max oc. I run a 8hr small fft and then 8hrs blend to make sure my rig is 24/7 stable.

Try getting a c batch.

I'm using mine currently and signed up for Asus exchange program for these boards. They'll contact me for the exchange when available.

All my systems are 24/7 stable by 8hrs small fft then 8 hrs blend. I test them roughly by using Linx 25 passes with around 3-4gb of ram test out of 8gb.

Just use it. Asus has a replacement program which by that time you'll get a new board with a newer rev. and bios.

Thats a newer batch. So no.

Finalized my OC. L042B291 4.8ghz@1.37v Linx stable and 8hr+ prime small fft and blend.

I5 2500k
2x4gb G.Skill
Asus P8P67 Pro
OCZ Agility 2 SSD

1 hour down 7 more to call it stable. Was hoping to do 1.35v@4.8ghz but gonna...

2500k L042B291 4.8ghz@1.35v passed linx. Gonna try a 5ghz run.

edit: just a average batch. looking like i'll need 1.37v just to get 4.8ghz 24/7 stable / 8hrs prime stable.
