Adding RAM and Settings

[mboss]

I installed some new memory (2gb matched pair) in my system... it's running fine but I'm wondering if I have the optimum settings... I pasted the configuration below... there are differences in the latency settings for the 1 GB that came with the system (2x512 in slots 1-3) and what I installed... (2x1GB in slots 2 and 4)... Motherboard is Intel D875PBZ... latest BIOS from intel...

 

Should this be matched up for optimal performance If so, how's that done ? Should the RAM be in contiguous slots or as installed ?

 

Thanks,

You should not mix memory with this platform I woulod just suggest using 2-1.0 Gig modules for best performance.

Thanks... I went to the TSXpress site and went through the steps... set the timings for all the RAM to 2-3-3-6 and my systems running VERY well... much faster... I will monitor for problems and pull the 2 512MB modules if something goes wrong... but all seems good for now...

 

againg thanks... MB
