MIxing sizes

post #1 of 5
Thread Starter 
Just wondering I have 4Gb kingston atm and wanted to add another 4Gb but the 8Gb kit is not much dearer but was wondering in this day and age does it matter about mixing sizes? As in having my already 4Gb and adding in 8Gb or what is peoples view on this?

Thanks

on intel it is a massive problem, but it shouldnt be as big of a deal on AMD... that said, i would avoid it if posible.... there is a setting on phenom IIs that will let you run each mem slot dependant to a single core... i think this would be the best option if you must use different size DIMMs, but your best bet is just to stay away of different sizes and frequencies/timings smile.gif

I have 12 gigs in my sig rig, 2x4 Corsair XMS3 DDR3 1600 and 2x2 gigs of Corsair XMS3 DDR3 1600 with no issues.
They are identical (speed, timings, voltage etc) except for the size. When you start mixing brands is when you can sometimes get problems.

Yes sometimes it does matter, especially on DDR3 RAM. Even with the same frequency, latencies and voltage there is no guarantee that mixing of two RAM kits - even of the same part number, will function without issues. It's always a crapshoot. At the price of DDR3 RAM, I'd buy one matched 8 GB. RAM kit approved for your CPU and be done with it. But it's your money so if you feel lucky you can always give it a try with mixing. wink.gif
