Dual Channel RAM upgrade

I'm thinking of adding some more RAM in the future and was wondering how I should go about it?

Here's my specs (copied from Speccy)

Operating System
Windows 7 Home Premium 64-bit SP1

CPU
Intel Core i5 3570K @ 3.40GHz 29 °C
Ivy Bridge 22nm Technology

RAM
Patriot Intel Exteme Limited Edition
8.00GB Dual-Channel DDR3 @ 800MHz (9-9-9-24)

Motherboard
ASRock Z75 Pro3 (CPUSocket) 31 °C

Graphics
24EN31 (1920x1080@60Hz)
Intel HD Graphics 4000 (ASRock)
3072MB ATI AMD Radeon HD 7900 Series (Sapphire/PCPartner) 32 °C

Hard Drives
1863GB Seagate ST2000DM001-1CH164 (SATA) 30 °C

I would just buy more of the same RAM, but I can't find it anywhere.

Here's Amazon's page for it:

Any suggestions?

What are you doing that requires more than 8GB? Newegg shows that RAM as discontinued but NCIX still lists it as on backorder. If you really need another 8GB I would contact NCIX and verify they will be getting more of it.

Nowhere else lists it at all. You could also buy a 16GB kit and sell that. Or try mixing it. You never know if that will work well until you try.

I plan on getting into computer animation, 3d modeling and such in the future and figured I'd upgrade while I had the money.

Would another brand of 2x4gb sticks work so long as they're the same Mhz and latency?

You don't necessarily need to have the exact same make and model of RAM, though that certainly makes things easier.

In general you want your RAM to match timings (so for you 9-9-9-24) and frequencies (for you 800 MHz, which is actually usually reported as 1600).

Also you have to make sure that your two matched sets go into their own separate DIMM banks. Your mobo should have two of these DIMM banks (one bank/2 slots for each set of dual-channel memory). I'm assuming your existing RAM is populating one bank already. If you mix brands make sure both of your new sticks go into the other DIMM bank. Bottom line: you can mix brands across DIMM banks but never within a DIMM bank.

OK so my mobo has four slots and the ram sticks are in the first and third. So would I need to arrange it so that the current sticks occupy the first and second and then the new ones in the third and fourth?

Not necessarily. DIMM banks aren't always in consecutive slots. Your motherboard's manual should have a section in it where it tells you the order in which to slot RAM. Follow those directions.

But if your existing sticks are already in slots 1 and 3, then it's almost guaranteed that 1+3=one bank and 2+4=second bank.

All right! Thank you very much!
