Bad stick of Ram


Recommended Posts

Ram guy, can you explain to me the diffences between to 2 versions of the same ram I have?


And can this be a compatability issue im having.


The first stick I bought a long time ago, it is cmx512-3200LLpt xms3205v 1.1

The second stick I got a few months ago cmx512-3200LLpt xms3205v 1.2


I have both installed on an Asus A7n8x motherboard, & am wondering if the versions have different programing, which in turn causes memory issues on this board? :confused:

CMX512-3200LLpt XMS3205v 1.1 = Winbond -5 Rev B IC's @ 2-2-2-6

CMX512-3200LLpt XMS3205v 1.2 = Winbond -5 Rev C IC's @ 2-3-2-6

I would just set the timings manually to Cass 2-3-2-6 with the Rass to Cass set to "3" and set the Dim Voltage to 2.8 Volts and you should not have any problems.

I had posted a while back about 2 sticks of CMX512-3200llpt that had different memory timings. 1 was 2226 & the other was 2326. As to your instructions Ram Guy, I set both timings to your specifications. Still had problems. I tried everything. I went as far as buying another stick with 2326 to pair with the one i had. Still had reboots, errors,etc.


Frustrated, I enlisted the help of a friend. We Prime 95 the 2326 pair, it failed in 4 minutes. I then took those out, & tested the 2226 stick, figured it was good since it went 4 & 1/2 hours with no errors. Tested the ram i had just purchased, and after 2hrs with no errors, decided to test 1st ram with 2326 timings. Failed 2 minutes into test.


I then wanted to see if I could pair the 2226 with the new stick i just bought 2326. Over 9hrs later in Prime 95, I finally got what I was looking for in the first place, A stable machine period.


I would like to RMA this bad stick for a replacement.

Currently have that set up with the new stick of 2326 & the old stick of 2226, set to your specifications. Works fine, just not with the first stick of 2326.
