I installed Crucial memory modules earlier this year while I was running Windows XP. I just reformatted the hard drive and installed the Vista operating system that came with my PC. The add on modules are no longer recognized; only the factory installed memory is visable on a scan. Does this mean that the memory was compatible with XP but not Vista?
This is the second time that a memory stops working. (in 2 Weeks). New PC i'm doing.
The first time i RMA the memory, they give me another. All ok. But again, another memory, not the new one, stops working. I changed the slots and tested all combinations and have another one to RMA.
Board: Msi H97M-G43
Memory: 3x Ballistix VLP 1600 CL9 (BLS4G3D1609ES2LX0CEU)
Is this motherboard compatible with the memory ? Its possible that the motherboard is "burning" the memorys? I marqued the Slot (one blue) that the memory stops function and now i have the two black slots with the two memorys running, all ok until now. (2 days only testing).
Never changed the option "OC" at the motherboard memory option. Its all Stock
Thanks in advance.
Among the QVL are chips from Samsung, Micron and Apacer. Will Crucial memory
Thank you for contacting us. What is the make and model of the system? That will help clarify why you may be seeing different speeds within the chip.
2) The memory modules will actually run at the speed of the slowest memory module. The faster memory will clock down.
3) Yes, you are correct it will adjust downward.
4) The memory speed will be dependent on the FSB speed. If the speed is slower the memory will most likely become unstable, like you are currently seeing.
Please let me know if you have any other questions or concerns.
