Compatibility of CMX4GX3M2A1600C9 with AMD Phenom II X2 550 processor


Recommended Posts



I am wondering if there are any compatibility problems with this memory. I am currently using two slots on my motherboard for a TW3X2G1600C9DHX kit (2 x 1GB memory), and have filled up the other two slots with this new kit (2 x 2GB memory). Currently the Windows 7 memory diagnostic tool is telling me that there is a hardware problem with this memory. Am I having compatibility issues?


Motherboard is a MSI 790fx-gd70, processor is AMD Phenom II x2.


Thanks in advance for the help.

I ran memtest86+ after reading around the forum, and I get a wall of red looking something like this:


Tst Pass Failing Address Good Bad Err-Bits Count Chan


2 0 00123fb1ebc - 4671.6MB ffffffff 00ffffff ff000000 24

2 0 00123fb1f44 - 4671.6MB ffffffff 00ffffff ff000000 25




As the memory is currently arranged, Windows 7 boots, and the BIOS recognizes 6 GB of RAM as installed.


The windows memory diagnostic tool gives this message:


"Hardware problems were detected. To identify and repair these problems, you will need to contact the computer manufacturer."


Then when the computer boots the following time, I get a BSOD at login, with a message too long to read in the 3 seconds the blue screen is up.


Could this be a result of mixing memory types? The timings for the two kits are the same, and from the same company. I will try removing my old RAM and booting only with the new kit in a short while, and get back to you with the results.

Both sticks pass Memtest86+. It seems to be the kits don't work together, which is a shame.


I'll post the BIOS info when all sticks are installed, just for kicks.


Current CPU Frequency 3.10 GHz (200 x 15.5)

Current DRAM Frequency 1600 MHz

CPU FSB Frequency 200 MHz

CPU-NB Frequency 2000 MHz


FSB/DRAM ratio 1 : 4

Adjusted DRAM Frequency 1600 MHz

DRAM Voltage 1.80 V


The Memory Table reads


DRAM TCL 9 9 7 7

DRAM TRCD 9 9 7 7

DRAM TRP 9 9 7 7

DRAM TRAS 24 24 20 20

DRAM TRFC 74 74 59 59

DRAM TWR 10 10 8 8

DRAM TWTR 5 5 4 4

DRAM TRRD 5 5 4 4

DRAM TRTP 5 5 4 4


each column being a different DIMM slot, in order from 1 to 4.


DIMM1 and 2 hold the new kit, and DIMM3 and 4 hold the old one. The processor is not overclocked, and I haven't tinkered with voltages. Please let me know if I'm forgetting anything.

Try it with all 4 at 1333 or even 1066. Your memory controller may not be able to do 4 up at 1600.


If you can get stable at 1333, then you can try and see if see if your BIOS will allow you to increase the voltage to the memory controller as you may need extra memory controller voltage to accomdodate the load of 4 modules.
