Could you tell me the exact (best/safe) Bios settings for this memory.

Best regards

Seems like they are optimized. The memory settings are on the modules themselves or the packaging.

Try testing each module individually to insure neither is defective. You can also run memtest86+ for confirmed results.

Thank you

I going to test each module individually.

One question, the command rate (CR) should be 1T or 2T??

[Tradesman]

2T would be best

Disappoint with GSKILL

Hi,

i?ve test each module individually and one of the module are given many errors on the memtest86.

Already contacted the store where I purchased the memory, and they said because it?s a KIT (2x2GB) i have to return both modules the good one and the bad one.
They said it?s because the GSKILL. I don?t understand why i have to return both modules. So because of that i have to stop my new computer!!. I?m very disappoint with GSKILL .Why can?t I return only the bad one???

(sorry about my English)

Best regards
