Decided to turn HT off today, as its a 'heat' hog, and not much benefit, if any, anyway.

Upped BCLK to 211 @ 19 Multi (4005GHz) and tested with same voltages as above, and all passed LinX etc no problems. Decided to reduce vcore a little, so took it down to 1.40v, and all passed no problems...BUT!

2Gb RAM disappeared just like that, 4Gb instead of 6Gb? BIOS and OS.

Dropped vdimm to 1.64v, and presto......I have my 6Gb back?, not tested for stability as yet.

Any thoughts guys?
Hi.

Yeah, I'm sort of experiencing the samething....

It seems that if I go over a certain speed with 6GB, mainly 1900, 2GB just dissapear...

anyone else experiencing this where 2GB RAM just dissapear with certain settings?
