Evening all, this might be a little long winded so i apologise but i'm getting nowhere so need some help.

Had one stick of THIS running in my system perfectly fine so decided to add another stick giving me 8GB as it was a cheap upgrade.

Fitted the new stick this morning and all seemed to be fine untill i started getting random BSODs that i couldn't reproduce, they just happened whenever. Ran memtest with both sticks in and i get an error on test 3 saying 80808080 is good whilst 80848080 is bad.

If i run each stick on their own memtest will pass with no errors but adding the other stick again produces the same fail in the same test. I've also tried switching which slot each stick is slotted into which doesn't help.

All BIOS options are set to auto and i've also chosen load bios defaults but none of this helps either.

One thing i did notice was according to the website, the timings should be 9-9-9-24 but leaving the BIOS options to auto leaves the RAM running timings of 8-8-8-20. Originally i thought this could be the problem but manually setting the timings to what Corsairs website states also resulted in a random BSOD.


Have i just been stupid in expecting 2 single channel sticks to run fine paired together and what are my chances of returning the new stick to No competitor discussion! if it clearly isn't faulty?


Thanks.
 
What board you using? Post current dram and CPU vtt voltages,might need more with 16gb,try 1.10cpu vtt,and dram 1.55v
 
Yh my bad,depends what board he's using,CPU northbridge on older boards might need one/two clicks more
 
I'm using an ASRock 960GM-GS3 FX.

According to cpuz the voltages are 1.000 V for the CPU because of Cool n Quiet and ram voltages are 1.50 for JEDEC #1 #2 & #3

PSU is a Gigabyte Superb 550p which is a 450w.


I've just taken one stick out for now so i can at least use my system but really want to get the second stick working if possible.
 
i dont know much about amd systems but its not cpu voltage its northbridge voltage you would need to adjust,see what auto is using and add only one or two clicks more and test,as for dram you could manually set it to 1.55v and see if its any better
 
This morning i tried setting timings back to what Corsair states the ram should run at so i got it setup as 9-9-9-24 2T (1336) rather than the 8-8-8-20 1T (1066) the board sets it to when left at auto.

Also set the ram voltage to 1.55V and memtest passed with both sticks for the first time ever. Not getting too excited untill i've used the system enough without getting a BSOD but fingers crossed your voltage bump advice seems to have paid off so thank you.

On a side note though, could the board setting the wrong speed and timings have caused errors and BSODs?
 
yes if its setting the timings too tight and dram voltage too low,auto doesnt always set the right settings,see how it goes for a few days,then keep voltage at 1.55 and try 8-8-8-24-1t timings
 
Sorry to bump this again but i'm back in the same boat, well sort of.

Having the BSODs constantly happen, i sent the extra 4Gb stick back for a refund and put it towards a proper matched pair ruling out the possibility of incompatibility. Now i'm running a 8GB Corsair XMS3 kit and still getting BSODs.

Could it be pure bad luck i've been sent bad ram again or is this a board problem seeing as my system seems to run perfectly fine running 4GB single stick (either stick in either slot) but adding the second stick brings back the BSODs.
 
Also, to add to this.

In MemTest, both sticks give out no errors when tested in either slot but when i ran MemTest with both sticks installed i let it run for a minute max as it had already thrown up over 3000 errors and i seen no point continuing.
