Promos or Qimonda?


Recommended Posts



I received two 2GB gifts of Corsair RAM for Xmas- specifically the XMS2 TWIN2X2048-6400C4DHX. I want to keep just one of the 2GB matched pairs, and from my research within this wonderful forum, I find one of my sets has Promos as the IC and the other has Qimonda.


So, which supplier has the better reputation for stability, overclocking ability, etc., etc.? It seems Micron is the "cream of the crop"??? Where do these others rank?


Thanks for the advice!

Excellent. Thanks for the reference thread.


FWIW, I have tested both sets in my MSI K9AG Neo2-Digital motherboard with the AMD Athlon 64 X2 5000+ "Black Edition" processor. Using MemTest, I found both sets (Promos & Qimonda) were stable at a 14.5x multiplier for 10+ hours but BSODs ultimately resulted when I increased the multiplier to 15x running MemTest. I used the rated 2.1v and 4-4-4-12 settings for these modules. I am unable to boot, at stock CPU voltage, when I increase to a 15.5x multiplier.


I will say I was expecting a bit more than the slight overclocking which I have been able to achieve, especially based on the information found at:




Granted, I have not adjusted CPU voltage upward, but considering the results from that testing, and other similar tests/results of this particular AMD CPU, I was hoping for a stable 15x multiplier. I am unsure how much the RAM is to blame, but I think I have discovered my system's upper limit when using Corsair RAM- independent of the IC supplier.
