ASUS P5E3 - Memory Question


Recommended Posts

Hi, i'm upgrading my older computer with some fresh ram, i've been away from the computer hardware quite sometime now so i have a few questions.


Does my motherboard ASUS-P5E3 support 2x4GB kit - XMS / Dominator / GT.


Can i use faster mhz memorys from Corsair on my board, even thou my motherboard might not support the actual speed, i mean compability-wise.


These are the ram i'm concidering for my board:

2x2GB - CMT4GX3M2A1866C9

2x2GB - CMT4GX3M2A1600C7

2x4GB - CMP8GX3M2A1600C9


If neither is working, i'd like to know the fastest and largest memory from Corsair that's been tested stable on my motherboard, thanks.

The specs for the Asus P5E3 look like it can run up to 8 GB. of DDR3 RAM with potential overclocking of the RAM to 1800 MHz. There are no guarantees when it comes to overclocking as my signature indicates.


The link below shows a whole list of P5E3 compatible memory all of which should work just fine. It also appears that the three part numbers that you listed should all work though they may not have been confirmed on this specific Asus mobo.

Thank you for a quick reply, but my most concerning question is can i use 2 x 4GB dimm's (Using 2 of 4 sockets to 8GB's of ram which is maximum) And let's say 2000MHz memorys. Just in theory, whould it work, is it generally accepted by motherboards to handle any dimm-size/socket as long you don't exceed motherboard maximum installed memory or do you have to use 4x2GB to reach 8GB? Saying 2GB/Socket-maximum size.


Sorry for newbie questions, was a long time since i was good at these things.

Yes normally you can use two or four modues to reach the maximum supported total memory *unless* the mobo maker advises otherwise in the owner's manual. Always check to be sure - especially with Asus mobos.


As far as the RAM frequency is concerned the RAM has been tested at whatever frequency it is rated/sold at but your CPU/mobo/Video card etc. must all be willing and able to run at higher than OE spec frequency to run the RAM overclocked at it's rated speed.
