Hi

I had real issues using my new Zotac H55 ITX board and Crucial RAM. It set the timings all wrong.

This RAM is part of a triple channel kit CT3KIT25664BA1339

Crucial states timings of 9-9-9-28

Couldnt even get win 7 to install initially....then when did install ran very buggy....would randomly freeze up when watching films etc

BIOS had set timing to 9-9-9-24. So set it to 10-10-10-30...as apparently there is a known bug on this board where CL9 CAS needs to be set to 10.

Windows is still freezing up on me! Everything ran fine in my other rig before changing to this mobo and this processor

There are several other settings in BIOS I am not sure of....please advise best settings for the following :

DRAM tCL
DRAM tRAS
DRAM tRP
DRAM tRCD
DRAM tWR
DRAM tRFC
DRAM tWTR
DRAM tRRD
DRAM tRTP
DRAM tFAW

Im sure its the RAM messing my system up. CPU seems ok, voltage all reporting ok. GPU has all correct drivers installed. SSD running ok

I could only get windows to install by removing one of the 2 x 2gb sticks I had installed

Very lost, please help!

There is also PEG Port (NV PCIE Congifg) and PEG Force GEN1

One is auto, the other is enabled.

Also this is running at 1.5volt (per CPU-ID) as per manufacturer

What the max I can run it at for stability

Not sure what going on with this board, giving me big headache

The CAS being set to 10 bug is weird enough....but everything just running so unstable

Installed new G Skill CL8. Mobo likes this RAM, all runs perfect on auto. Sold the crucial on good old gumtree
