Recommended Posts

I bought 2gb of Corsair TWIN2X2048-6400C4D in November. Today I received another 2gb of TWIN2X2048-6400C4D for a total of 4gb. I am running vista x64 and started having issues (lockups, programs crashing) as soon as I installed the new memory. Motherboard: Gigabyte GA965-DQ6 F9 bios. New ram in slots 1&2. Old ram in slots 3&4. CPU-Z shows slot 1 & 2

Part Number: CM2X1024-6400C4D

CAS# Latency: 4.0

RAS# to CAS#: 4

RAS# Precharge: 4

Tras: 12

Trc: 22

Command Rate: 2T

--------------------------------------------------

Slot 3 & 4 show.....

Part Number: CM2X1024-6400D

CAS#: 5.0

RAS# to CAS#: 5

RAS# Precharge: 5

Tras: 15

Trc: 22

Command Rate: 2T

 

Can someone please assist me in finding an answer?

Excuse me...... Am I hearing you correctly?????? I have 4 identically marked ram chips that are certificed 800mhz and you are suggesting I run them at 667Mhz. WHY???????? I PAID FOR 4 6400C4D sticks and am curious why the first reaction isn't " THEY NEED TO BE REPLACED WITH THE CORRECT MEMORY YOU PAID FOR". What is my next step now that we have determined that my first 2gb chips where MISLABELED. RICK

Yes I have not seen a MB yet that would run 4 modules at 800 MHz sorry but there is more loading on the memory controller as you add more modules, but to make sure its not a failing module you should test the modules one set at a time at the tested settings, The are correct from the SPD we use the same SPD for both just one has the correct part# probably a later production run, but the SPD is the same.
