Hello all,

I'm currently running an older ASUS M3N72-D Motherboard, AMD Phenom X4 9600 Quad Core CPU, and OCZ Dual Channel Platinum PC8500 DDR2 1066MHz Memory (2 x 2G) with 5-5-5-18 Timing at 2.1 - 2.2 Volts. I am now using a dual boot Windows 7 x86 and Windows 8.1 x64 setup. Since I now have an x64 OS, I'd like to upgrade to 8G of ram, mostly for gaming and music recording. I'm finding that neither Tiger or Newegg carries my current memory sticks. I cannot seem to find DDR2 PC8500 1066MHz sticks with the same Timing and Voltage. I'm also finding that it's apparently not a good idea to mix Timing or Voltage. My question is..... Do I go with (4 x 2G) of all new at 800MHz and scrap the two I'm using now, mix my two existing sticks with (2 x 2G) at different Voltage and Timing, or leave as is? Unfortunately I'm not privy to the dos and don'ts of modern memory mixing and matching! Any help would be greatly appreciated!

Any particular reason why you feel that's the best direction to go? I'm not doubting you, that is probably what I'll end up doing. I have yet to do any real price comparisons though. I'd just like to get some input as to if anybody has experience comparing (2 x 2G 1066MHz) against (4 x 2G 800MHz)? Also wondering what some of the ramifications are of mixing Voltage and/or Timing. I've read some articles, but I'd like to hear the opinions of some veterans here on the forum.

1066 you need to OC the ram to get that. If you wanted faster ram, you should upgrade your mobo and cpu.

Mixing ram sticks almost always ends with BSoDs etc

I see that two sets of (2 x 2G) sticks are relatively cheaper than one set of (2 x 4G) sticks. Is there any major difference? I've read that two sticks will be less work for the memory controller than four? I'm also seeing that there are pairs of sticks sold specifically as dual channel. I know this MB is dual channel capable, but what's the difference between two pairs of dual channel and four sticks not listed as dual channel?

Kits have been tested to see that each stick works with the others. 2 kits can have problems. 2 x 4gb would be better than 4 x 2gb.

Hefty price diff between 2 x 4G and 4 x 2G. Could almost pay for most of a new MB for the price of a 2 x 4G pair. I guess 2 x 4G is the way to go. Just sucks I can't integrate the pair I already have. I built this thing many years ago with the idea that I could keep upgrading, figured I'd be able to find two of the same years later because it was new at the time. If I could find two of the same would that be ideal seeing as I already have two?

Now you should also consider whether to throw money at it or upgrade to say lga1150

Eh, I tend to lean towards AMD, but I guess either way a new MB may be in my future. I've already priced out a whole new build, but it'd only be because I want to. The build I'm using now, although getting old, still runs the best of games or Cubase (music recording software) with no problems. A new build would be a "go as I get paid" type of deal! For now, I think your suggestion to buy a kit of 4 x 2G 800 MHZ or 2 x 4G 800 MHz is the way to go. I'll have to decide which..... Thanks for all the input, much appreciated!
