Guy's, I am in the process of putting together a Sandy Bridge based system around the Asus P8P67 Deluxe Motherboard. For Memory, I was going to get 2 sets of RipjawsX 8GB Kits each having 2 x 4GB Matched Pair for a total of 16GB of RAM. Unfortunately, every dealer out here in my country is out of stock for the 8GB Kits. However the 1 x 4GB Single stick kits are still available. Would it be wise to simply get 4 of these for 16GB RAM? Are there going to be any problems running Dual Channel with these or running at the rated speed of 1600MHz?
Same brand, same timings.....you should be fine. I'm currently running 6GB @ 1 - 2 - 1 - 2 ( slot wise) configuration. The 2x1GB sticks are rated at 1333MHz, 9.9.9.24 (Corsair) while the 2 x 2Gb sticks again are corsair but a different model. They are rated at1600MHz but same latency (9.9.9.24) and have scaled down to run with the 1333MHz sticks. No issues.
As long as the actual specs are correct the "matched pairs" is a lot of gimmick. And unless you plan on overclocking, save the money, and get some kingston valueram instead. I've yet to have issues with kingston memory, and I've been using them since I was 16... (With some off-brand excursions when there was a lot of money to save) //Svein
I would heavily go against Kingston ValueRAM ... they are utter **** for overclockers ... I've had so many problems having it installed for overclocking. Even if I don't OC the RAM itself, it somehow bars my system to be overclocked. 240x12.5 = 3000 MHz is how my CPU is set, and since my RAM ratio is 3:5, that means I take my BCLK of 240 * 5 / 3 = 400 MHz ... DDR that and you get 800 MHz, which is the stock speed for my RAM ... and it will be unstable. With these G.Skill RAM, overclocking was so much easier and I didn't even need to raise my voltage and I can even tighten my timings as well. So from personal experience, I'd really suggest you look elsewhere for RAM than KVRs. I'd only recommend them for workstations but not gamer rigs. deltatux
