Originally acquired 2 kits of F3-12800CL9D-8GBXL. With each package showing DDR3-1600 PC3-12800 4096MB x 2 CL9-9-9-24 1.5v.
Was having problems and running Memtest86+ determined that one stick in one of the kits was faulty. Unfortunately this was not determined until well after 30 days and thus, the kit was not replaced immediately by the retailer. However, the retailer did manage the RMA process for me and it was 6 weeks before I received a replacement kit. It seems they do their testing first to confirm the problem.
They confirmed the problem and a replacement kit was received Friday, June 17, 2011. The replacement kit had the identical labeling as shown above.
This time I decided to run Memtest86+ immediately. I placed the old kit in slots 1 (A1) and 2 (A2) and the new kit in slots 3 (B1) and 4 (B2). When Memtest86+ was run it showed that the modules in A1 and A2 were PC3-10600 while B1 and B2 were PC3-12800. I ran the test for approximately 4 hours? 2.5 passes and no errors were encountered.
I then rebooted the system and ran System Information for Windows and CPU-Z. Both apps confirmed the findings of Memtest86+ regarding the differences in the two kits.
In the BIOS settings, I did change from AUTO to X.M.P. and set the memory to PC3-1600.
So, the question becomes? do I have a problem with the old kit? If not, any suggestions as to how I can get the modules in sync with each other.
Cheers, Bob
