Windows 7 Random BSOD

well ya that's what i was getting at it does the job but only skims the surface! ok so i started off with 1 2gb stick on the board i ran it for a total of 21 hours with 52 pass's no errors so i am now trying both sticks right now so i will let you know what happens then. but here is the thing i did not pick the parts out for this pc i just built it i don't see the ram anywhere in this mother board booklet for being correct for this board.

motherboard: asus P7P55D
Ram: ocz30b1600lv4gk

i know the motherboard booklet says do not put any ram over 1.65v on the board and this ram is 1.65v.

if this test comes back with no errors i will be lost... sigh

thanks for all the help guys hopefully i can learn something new from this lol

ok after putting the second stick of ram in i did not even get 1 pass done and there were already over 1020 errors

test: 4
Failing add:0040200080-1026.0mb
Good:db99eb9d
Bad:db59eb9b
Err:00c0000

test: 4
Failing add:0004020030-1026.0mb
Good:db99eb9d
Bad:dbcceb9b
Err:00550000


to sum it up the
First test: i did i had 1 stick in Dim-A1 (no errors 52 pass)
Second test: i had both sticks in Dim-A1, Dim-A2 (1020 errors 1 pass)
Third test: i am ruining now but i took out the stick from Dim-A1 (it has made it threw its first pass with out any errors)

i think the problem comes from having both sticks installed on the board at a time can that be timing issues?

We have limited it down to 3 possible causes: a bad motherboard, a bad stick of RAM, or incompatibility between the sticks and board.

Make sure it isn't the 2nd stick of RAM. Run Memtest on that stick only, in Slot 1.

I suspect it will pass, however. Most likely the sticks are mismatched.

Try setting the RAM timings to 9-9-9-24, and then test both sticks at the same time.

ok well i have had the second stick in slot A2 and have had the test runing for bout 4 hours now no errors so the sticks are not bad i know that for sure so ill have to take a look at the timeing in bios but im pretty sure its going to be incompatibility because the sticks of ram are not mentioned in the motherboard booklet what ram would u suggest for me i need 4 gigs at least

the bios had the ram set to 7-7-7-20 so i changed it to 9-9-9-24 with both ram on the board im running the test now

ok well with both sticks on the board and 18 hours and 24 pass later no errors so im gonna stop the testing on the ram and run the system i will post up results hopefully no more BSOD!!!!


thanks guy s

alright so it has been bout half a day with no BSOD ill keep ya updated also do you guys have any go articles i can read about Ram timing i would like to know a little more about it thanks!!
