Never got a reply to my above Q due to some kind of argument going on!

I tested my 2600k tonight and got to 55x Multi (I lowered BLK) before it would fail to boot to Windows, not sure if settings/voltage was limit or if 55x was Max!

Anyhow be on my 2700k in day or so when I can be bothered swapping over!

What was the normal highest Multi for 2600k's or was 55x normal and 58x luck on a good sample?
