TCL - 5 OK
TRCD - 5 OK
TRP - 5 OK
TRTP - 4 Set to Auto, or select 2-4?
TRAS - 15 OK
TRC - 48 Do not have 48 - 42 is highest value
TWR - 10 Only have 5,6,8
TRRD - 4 OK

TWTR - 4 OK
TRFC0 - 195 OK
TRFC1 - 127.5 OK

tRTP - 4, tRC - 42, tWR - 8, and give it a shot. If no go, take tRFC1 up to 195.....still no go, take both tRFC to 220+

TCL - 5
TRCD - 5
TRP - 5
TRTP - 4 2-4 selected.. Should this be set to auto?
TRAS - 15
TRC - 42
TWR - 8
TRRD - 4

TWTR - 4
TRFC0 - 195 Tried 195, then next one which was 327
TRFC1 - 127.5 Tried 195, then next one which was 327

I'm making the assumption that these are set for both sets under the 2T config, correct?



Still no luck. BSOD. Only gets a few seconds past Bios page when booting

DRAM voltage = 1.9V
HT Voltage = 1.4V
NB Voltage = 1.4V

[GSKILL TECH]

Do you have 3-5 for tRTP? Try 2.1V on the DRAM Voltage. Yes, command rate should be 2T. Keep us posted on the results.

Thank you

I tried with 3-5 selected for trtp. Also tried with 2.1V DRAM. Still the same results, BSOD doesn't even get a chance to display. Computer goes directly into a reboot.



Should I be testing each individual stick to see if one is bad? If so, what is the best way to go about this?

[atmos_sc]

Update --- I ran several tests with memtest and all came through with no errors. To the best of my knowledge, my mem is healthy.

[Tradesman]

Is the system itself stable now?

Is the system itself stable now?

Yes, actually the system has been very stable.. aside from me trying to make changes to the bios settings. That is, stable because I had to resort to changing all bios settings back to default.

Any changes I make, that have been listed in this thread or any other on this forum for configuring my memory to work at 1067,, have not worked.

Apparently the BIOS has been a problem with this mobo and may be a big part of ur problem, 15 updates in the last 7 months or so, latest is 1601 - 9-15-2009 which followed, 1404 from a week earlier (9-9-2009)
