G'day,

I have a microstar ms6339 motherboard that I'm told will only take PC600 or PC800 ram.

Is this true or can other types be used?

Please help.

Quick practical addendum for (and thanks to ): a few real-world points to avoid surprises when you source or fit memory for the MS-6339.

RIMM-based motherboards have installation quirks you will not see on normal DIMM boards. The board expects matched modules across memory channels and usually requires continuity plugs (CRIMMs) in any empty slot to close the memory bus. If modules are not installed in the correct sets or empty slots are left open, the board commonly will not POST.

Buying tips: try to buy matched modules or a complete kit rather than single sticks. Ask sellers for clear photos of the label/part number and for a return policy or a POST proof. Prefer known manufacturers and identical sizes; mixing different capacities or speeds tends to force the system down to the slowest module or cause instability. When you get the sticks, test them with a bootable memory tester (memtest86 or similar) before trusting them in daily use.

Quick troubleshooting checklist if the system will not POST after a memory change:

  1. reseat modules and latches; try one module in the primary slot;
  2. install CRIMMs in empty slots;
  3. clear CMOS/reset BIOS defaults;
  4. try a different module or slot to isolate a bad stick;
  5. update BIOS if a later version mentions memory fixes.

If used RIMM cost is prohibitive, replacing the motherboard with a more common DDR/DDR2 board is often cheaper long term. Check the MS-6339 manual for exact population order and maximum supported sizes before purchasing memory.
