I had (to my surprise) a memory module go bad in a machine. Using memtestx86+ and prime95 i was able to isolate a single failing module, and I properly RMAed it to Corsair. I shortly received a replacement module and installed it in the machine. However I then noticed something was wrong again (and wondered if it was the other module from the first (failing) pair). But to my surprise it was memory I had received from Corsair.
The module type is: CM2X2048-6400C5DHX
I am quite sure that it is only this module which is failing because:
- Other (original) memory passes in slots which this module fails in.
- This module fails in other computers (which pass with other modules).
When looking at the replacement module received from Corsair, it doesn't look obviously new. The heat-spreaders aren't damaged/scratched, but the gold pins look more worn then the original modules in the machine (which have been moved/reinserted a few times. (However the plastic casing which the module arrived in does have the same batch/id number as the containing module (but not sure if these stickers are generated upon shipment?))
Have I just been very unlucky, and should just do the same RMA procedure for this module?
Or is it common for these modules to fail?
Does corsair have a QC problem they need to be aware of?
The machine in question:
- Memory: Two pairs of CM2X2048 pairs (8GB total)
- Motherboard: Asus M4A78-E
