P5N-T Deluxe BIOS settings for Gskill F2-8500CL5D 4GB

My system has been randomly hanging when using the AUTO settings in the bios , while having SLI ready memory set to "expert". the gskill website does not have settings for that particular mobo, so what specific settings should I be using to avoid such hang ups? Running it in sync mode (667 MHz) does not make the system hang, but I really want to make full use of my RAM.

Asus P5N-T Deluxe
QX9650

ive set it to 2.03 now

4GB, 1066MHz DDR2, stock no. F2-8500CL5D-4GBPK as per title

thats the memory i have, but pc wizard tells me it is sli ready, and in fact, when i set sli ready to disabled in the bios, the system hangs everytime even when putting in the settings for voltage to 2.03 V.

Ive set it to 2.05V now, but maybe i should just copy and paste whatever pc wizards says about the EPP profile #1:

EPP Profile #1 : Full Performance
Voltage Level : 2.1V
Address Command Rate : 2T
Cycle Time : 1.875ns @533.33 MHz
CAS Latency (tCL) : 5 clocks
RAS to CAS (tRCD) : 5 clocks
RAS Precharge (tRP) : 5 clocks
Cycle Time (tRAS) : 15 clocks
tRC : 48 clocks
tWR : 13 clocks

and use those as bios settings.

maybe then i wont get any more random hangs.
