G.Skill DDR3 8GB(2x4GB) Ripjaws X

[greenskynz]

Hi
I am looking at getting one of the below listed G.Skill DDR3 8GB(2x4GB) Ripjaws X before I upgrade to Sandy Bridge rig later on this year when Sata problem is fixed. So initially I would like to run them with my old mobo Gigabyte EP35C-DS3R (older Intel P35 chipset for Duo processors) which apparently supports DDR3 1333. I guess they will note work at full speed 1600 but would they work at all?

Also any recommendation to this list or other recommendations:
Gskill G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Sandy Bridge Optimized F3-12800CL9D-8GBXL

Gskill G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3-1600 (PC3 12800) Desktop Memory Sandy Bridge Optimized F3-12800CL8D-8GBXM

thank you very much
Paul

If that old mainboard actually supports DDR3 memory, either of those should work. They will automatically down-clock to 1333 speed.

Since memory timings don't really matter with modern processors, get the cheaper CL9 kit. I have 12GB of Ripjaws X DDR3-1600 CL9 in my Sandy Bridge machine (one 2x4GB kit and one 2x2GB kit), and it works perfectly.

well, since your motherboard doesn't support 8GB DDR3 memory it would be a waste as it only supports 2x2GB DDR3 dimms, also the board would not be able to support both at the some time, its one or the other

thats correct thanks. i managed to confirm this with the manual, before wasnt sure what to look for.

yes i think you are right about timings. in below article (see link) in conclusions sections reads that CL8 kits had some advantage only in video encoding tests.i am actually upgrading for 1080/50p hd video editing but doubt it will make much difference for home editing. but as mindless728 wrote my mobo doesnt support 8gb so I will just hold off when ready for full upgrade. thanks
