vhoeven Posted February 27, 2004 Share Posted February 27, 2004 I run a standard P4C800 setup (P4 3.0) without overclocking. I currently changed my slow Kingston's to 2 x CMX512-3200C2. It runs great. I happen to have 2 spare CMX512-3200C2's to be used in a secondary server but I can also use the old Kingston's as this is a fileserver without many memory constraint. The ASUS memory document for the P4C800 states that you can only use 2 units of CMX512-3200C2 (either blue or black bank) and not 4 ! When inserting all 4, all seems to work, so my question is WHY the limit on 2 slots and not all 4 as for most memory ? The units fit, without making contact with each other, so there must be a non-physical reason. Could anyone explain and/or help me with this issue ?

Corsair Employees RAM GUY Posted February 27, 2004 Corsair Employees Share Posted February 27, 2004 I think you would really need to ask ASUS for the reason they stated this, but in general I do not suggest more than two modules if you are over clocking. In addition, running the modules at Cass 2 would technically be over clocking the memory timings for Default DDR 400 Spec. However, there have been a few that have run with 4 modules with out problems. Also I would suggest that you gander at [URL=http://www.corsairmemory.com/corsair/products/tech/memory_basics/153707/index.html]Memory Basics Presentation[/URL]! This explains a bit about chipset and loading with more modules. Link to comment Share on other sites More sharing options...
vhoeven Posted February 27, 2004 Author Share Posted February 27, 2004 Thanks. Slick presentation which gave some extra insight. For now I run a standard setup (CAS 2.5 I think) without overclocking and all seems good with 4 sticks installed. I can always fallback to a twin1024 (at some considerable cost) in the event that I get errors. If I get an answer from ASUS (I doubt), I will post the results. Thanks again.

Corsair Employees RAM GUY Posted February 27, 2004 Corsair Employees Share Posted February 27, 2004 If the system is stable I would leave it where you have it for now, but I would suggest that you set the Di Voltage to 2.75 Volts and you should be fine.
