14gb ddr3= bsod and memtest errors

Hello,
I've got an MSI 770-g45 and I originally had 8 gigs of ddr3 1600 in it (4gbx1 2gbx2) and I eventually got a new set of 4gb sticks so that my setup was 4gbx3 and 2gbx1 (removing the extra 2gb stick). The computer was working fine but then started to crash in Windows and i ran memtest and got like 300 errors after several hours. tried memtest on the individual stick of ram that appeared to be getting all the errors and have ran it for about a day with close to 10 passes and no errors. I am wondering if there may be a clocking issue with 14gb because my mobo has a hard time understanding the 2gb stick (i only get the errors on the last 4gb stick and don't get errors when it is alone) any help would be greatly appreciated.

PS: It is not because I had the rame overclocked (although I did at one pooint.) it is underclocked to 1333 to keep the

Yesterday I posted a thread related to my Ram Error.

On my first run of the test (lasted about 1.5hours) It showed one error..

Later that night. I made NO CHANGES TO MY COMPUTER AT ALL. I just ran the test.

And got no errors.

Was a glitch on my part.

But in your case it seems your ram does have some errors, you should RMA it.

Instead of using 4gb's and 2gb's. Just get a SET of ram...

like 4GB 4GB 4GB 4GB

Ram works best when you have matching memory sticks. It is best to go from 2GB to 4GB, 4GB to 8GB, or 8GB to 16GB. Having random amounts of ram like 6, 10, 12, 14 all will cause numerous issues. It is best to fill up 2,4 or 6 slots of ram, not an odd number of slots or amounts of RAM.

In general it's perfect to have each slot with the same number of ram.

Or.

IF your mobo has 4 slots do it like this

Slot 1 2GB
Slot 2 4GB
Slot 3 2GB
Slot 4 4GB

But..It is always best to have the same GB of ram in each slot (Preferably the exact same model of ram)

THANK YOU ALL FOR YOUR REPLIES


My Slots are set up like so
Slot 1 4gb
Slot 2 4gb
Slot 3 4 gb
Slot 4 2gb


I will eventually be getting a 4th 4gb stick (right now all my ram is ddr3 1600 all gskill ripjaw but i have 4gbx2 ripjaw xseries, 2gbx2 ripjaw z series and 4gbx1 ripjaw z series.

1) Should I get 2 more of the 4 gb ripjaw x series or just 1 more 4gb stick either x series or z series?

Also as a side note i get no bsod so far running 12 gb in this form:
Slot 1 4gb
Slot 2 4gb
Slot 3 2gb
Slot 4 2gb

2) Should I be running as mentioned before? and is this dangerous to my computer?

oh and 3) does this mean I don't have dual channel mode

Get the same exact memory as your other three 4GB modules.

There are probably no BSOD because each kit is a matched pair. (2 x 4GB + 2 x 2GB)

When you use one 2GB and one 4GB module (in same color slots), they may not communicate properly. It is like a kid and an adult, sometimes it can be difficult to stay on the same page.

If attempting 18GB, the 2GB module should be in slot 2. To factor out the CPU memory controller causing instability, you can try DDR3-1333 8-8-8-24 1.50V.

Don't forget for DDR3-1600, manually input DRAM frequency, timings, voltage, and increase CPU-NB Frequency to 2400MHz, CPU-NB (VDDNB) Voltage +0.1V. This will be necessary to support full slots @ DDR3-1600, and for optimum performance.

As long as you have two modules installed in the same color slots, it will be dual channel.

Keep us posted on the results!

Thank you

Thank you so much!!! I just ordered my 4th 4gb stick of Gskill ddr3 1600 (they are all the same speed and everything) then I will have all matched pairs (2x2gb 2x4gb and 2x4gb) and will be running 16 gigs. Thanks again so much!
