Back in March I bought the F3-12800CL9D-8GBRL Ripjaws for my new Sandy Bridge based PC.
The system was this:
MSI P67A-GD55 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost)
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
CORSAIR Professional Series HX650 (CMPSU-650HX) 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply
Not counting the video card, case, hard drive and other things.
Anyway, I haven't had any need to push the limits of my system and haven't bothered overclocking. The ram when I first got it wouldn't run at 1600 like it was originally advertised. I knew it may require manually setting voltage and other things so I just ignored it till now. But now with Battlefield 3 coming, as well as the Crysis 2 HD texture pack as well as The Old Republic (though it probably won't push much).
Whenever I tried to set the ram to 1600, the motherboard wouldn't even post. I wasn't sure if it was a motherboard issue or the RAM. So last week I ordered some more of the EXACT SAME model of ram. I decided I'd put it and try to determine what the problem was. I put the two new sticks in Slot 1 and 3, and moved the old sticks to 2 and 4. Still the system would not boot up when I turned on the XMB. So I took the two old sticks out and turned the XMB on i the bios, and sure it enough it booted up running at 1600 with absolutely no problem, it's been running at that speed for the past 12 hours without a BSOD or anything.
Here is screenshots of the info on the ram.
This is the old ram and it's info: Slots 2 and 4 are identical
And this is the new ram and it's info: Slots 1 and 3 are identical
Both of these are identical ram sticks. They even identify themselves to the motherboard as the same part number. But clearly something is wrong with the old ram because it says it's max bandwidth is lower than it should be.
It's almost as if the original two RAM are really F3-10666CL9D-8GBXL but think they are F3-12800CL9D-8GBRL. I really don't know, I've never run into this issue and want to know how I can get this resolved as soon as possible.
