8gb ddr3 1600 in an 890fx? Tags: Motherboards DDR3 Last response: August 7, 2010 9:58 PM in Motherboards Share Jouho August 7, 2010 6:30:37 AM Hi, I'm getting an 890FX mobo in perhaps next week, and I'm wondering if I can run 8 GBS of ddr3-1600 ram at 8-8-8-24 timings with it still being 1600, and not 1333 or something? System is AMD based, with a phenom II 955 More about : 8gb ddr3 1600 890fx Lmeow a b V Motherboard August 7, 2010 8:15:55 AM If you're using a Phenom II X4 955 I'm pretty sure you won't be able to run 4x2 GBs of DDR3 1600 MHz RAM @ 8-8-8-24, only 1066 MHz or 1333 MHz. If you're using the Phenom II X6 CPUs that's different. There's practically no noticeable difference between 1066 MHz and 1600 MHz except in benchmarks just so you know. Jouho August 7, 2010 9:10:44 AM Thanks for the reply. Another thing, let's say I get the ram to run at... 1333 at 8-8-8-24 with the 4gb, would I be able to run it at the same timing and mhz if I have 8 gb? I'm concerned about the ram not being as effective if I increase to above 4gbs.

If you have 2x4 GB then that's possible, otherwise I'm not really sure. Jouho August 7, 2010 10:11:11 AM Thanks again for the reply, I looked in the manual and came across this... this is from the pdf manual for the mobo. http://i36.tinypic.com/hu5cg0.jpg Ultimately what I want to know is... Will I receive better performance with 8gbs ram VS 4gbs (all 2gb sticks), or will the performance degrade if I increase from 4 to 8 or what? popaholic August 7, 2010 1:23:17 PM It only depends on what applications you will be running and how many programs you like to run at once. Lmeow a b V Motherboard August 7, 2010 9:58:17 PM If you need the extra RAM then there will be an improvement if you use 8 GB over 4 GB. Otherwise there's not much of a difference between 4 GB and 8 GB, you won't lose performance. Can't find your answer ? Ask !
