TWIN2X4096-6400C5C Replaced but still errors

[gbu]

I had a 6 month old self built PC with TWIN2X4096-6400C5C RAM sticks, i was getting a sluggish performance and lots of freezing and BSOD's, i ran BurninTest and Memtest, both gave lots of errors and Burnintest would cut out with error Verifying Data on RAM being the main culprit.

Anyway seeing as they were 6 months old the shop(microdirect) replaced them for me with the same model, however on return the performance was still the same so i ran the same tests and got the same errors.

 

I was reading other peoples problems via google that maybe there wasnt the correct voltage going to them, is this possible or could it be a bad batch or something else thats at fault?

Voltage setting is on the label of the memory itself. When testing with memtest, did you test ONE stick at a time in the same slot using Memtest86+ v4.10?

Thanks for the reply i will check the voltage on the memory.

 

I tested both at same time with memtest 4.10

Microdirect has said they can replace the RAM with another make as they say its not compatible with my MB but i thought it was.

 

My MB is ASUS P5QL/EPU, in the configurator it just lists the P5QL/E but i think this the same or is that wrong?

Ok i have run memtest again but i got no errors this time i left it running for an hour, is that long enough?

 

The voltage is 1.8v.

 

I also noted these numbers on memtest, are they as they should be?
