Default Twin3x2048-1333c9

I started getting BSOD and crashes a couple of days ago while either booting OS or gaming.

Stuff like MEMORY_MANAGEMENT error and PAGE_FAULT_IN_NONPAGED AREA

After trying memtest with both sticks in for about 3hrs (7-8 passes) it wasn't showing any errors.. but when i remove one stick the blue screens stop and crashes disappear..... I've tried the sticks in both A1&B1 and also A2&B2 slots and the errors persist.

I read that MEMORY_MANAGEMENT error could be related to other stuff like a bad HDD or bad PSU.

Also my timings/voltages are set to auto in BIOS, could this also cause the problem? what are recommended settings? thanks

Mobo : M4A79XTD EVO
RAM : Twin3x2048-1333c9 (CM3x1024-1333C9) (1.5v) (ver7.1)

Try 1.6v for the memory voltage. If it is not stable, disable Legacy USB Support in your BIOS temporarily for testing and test each module individually for 3-5 passes each with Memtest, which is linked on the left side bar of this page.

Well i'm probably doing something wrong... but i can't seem to get memtest to run from an iso .. (it works fine from a usb stick, but to boot from usb i need legacy usb support enabled)

I ran some more memtest86+ with usb legacy support enabled, this time tested both dimms individually instead of both at once for about 4 passes each and still no errors..

On the other hand, I ran prime95 on one stick for a couple hours... then went to run it on the suspect stick, which i put in the same slot with same bios settings, it would bluescreen/crash after a few mins.. i repeated this just to be sure and same thing again

If it's not a stupid question, how important is having USB legacy support disabled?

Also, i should clarify, that DDR voltage is indeed already 1.6, which is what my motherboard assigns as auto; when i said '(1.5v)' in my OP i was referring to what is printed on the back of the stick.. sorry for the confusion

Let's get them replaced, please use the On Line RMA Request Form and we will be happy to replace them. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.”

I submitted an On-Line RMA Request Form.
how long does it usually take to get a response?

Thanks.

I managed to get memtest to boot from a CD.

However, memtest shows my frequency as DDR400/200MHZ; Will the test still run properly like this?

Also after a short amount of time (less than one full pass) memtest starts steaming continuous errors referring to bad memory addresses.. it reached about 50k errors before i rebooted. This is with one stick of CM3X1G1333C9 from my 2GB kit installed.
is this normal behaviour for faulty stick in memtest?

Changing the following options in bios and memtest still sees DDR400

Frequency : from AUTO to 1333
Volts: from AUTO to 1.60


Just want to make sure it's the memory before i go through the trouble of getting it replaced

Sorry for the doublepost. = /

What happens when you test the other module by itself? As far as it reading the frequency wrong dont worry about that.

Confused

Ok so i did a few more tests and heres where i'm at:

I moved the stick that gave me 50k+ errors from B2 to A2 and the errors were gone...

I then tested the other stick in A2 which also produced no errors after one pass

I moved it to B2 and no errors after one pass... then i switched it out for the other stick, and this time no errors after one pass...

so i guess it could have just been dust in my dimm slot..

I know you said not to worry about timings but is it unusual that my motherboard detects both sticks as DDR400 in slot B2, but detects them both normally as 1333MHZ in slot A2?

Thanks RAM GUY

Edit: i will run memtest overnight or something as the most i have done is like 7 passes.. and that was from USB stick so i couldn't disable legacy USB support

Ok... finally done (my eyes feel blue from staring at that screen..)

Stick one ran for two passes before showing errors. errors were 22272 after 31 mins walltime

Stick two ran for 5 passes with zero errors after 1 hour 21 mins walltime.

These were both tested in the same slot

So... how much of a 'sure thing' is memtest?

can i be pretty confident or should i run some more tests?
