4 x DIMM, Max. 16 GB, DDR3 1800(O.C.)/1600/1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
*DDR3 1600MHz or above DIMMs work only on the Orange slots for one DIMM per channel.
*When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.
*Refer to www.asus.com or this user manual for the Memory QVL(Qualified Vendors Lists).
From crucial scanner , that will check if the specific mobo will handle the max ram.
Adding a lower pair at lower volts will drag the rest to same. Not bad as you'll not find much difference anyway if you have an old processor.
If you have a 32-bit OS then you'll need to reinstall Windows 64-bit to get the max out of ram.
As I said, both mine and those I've just missed are 1333MHz PC3 10666, not that I understand any of that, I'm just pedantically comparing numbers and letters! - What confused me was the fact that mine are 1.7v and those on sale were 1.5v
I was hoping to populate all available slots and get 6GB in total.
Assuming all would play nicely, I would not be unhappy with a drop in the overall performance due to any small mismatches.
As you say, my old CPU (Intel Core2 Duo E8400 @ 3.00GHz) would be unlikely to notice, as would I.
I have two W10 Machines which I'm using more now and would then use this machine for playing around with Linux 64bit distro's.
Never really understood the results from The Crucial scanner.
This time it's saying I can spend anything between £35 and £150 but only lists PC3 and PC3L 12800.
The ones I missed went for £12, not worth spending that kinda money just to play with 64bit. :(
I already have An Optiplex GX280 running "Mint 17 Mate" and a Fujitsu Esprimo running "Mint 17 Cinnamon".
Guess I'll just have to keep prowling around ebay waiting for another chance, ...as long as I can remember what will likely match!
Just looked up acerbic and I don't think I'm that bad. I just say what I think is the truth. Syd you know that damn well :) 4 Gig of ram should be more than enough for Mint so fill the other two slots with 2 x 1 GB compatible ram. Your CPU should handle it well and ram is cheaper to boot. (pun there I think).
