Basudeb Posted April 10, 2012 Report Share Posted April 10, 2012 Hi there, my PC have 2GB DDR2 800Mhz (KVR800D2N6/2G) installed and I want to install another 2GB and want to make it Dual Channel (Dual Channel increase performance). Now my question is do I just need another 2GB DDR2 800Mhz or I need this with same latency's also 6-6-6-18 (tCL-tRCD-tRP-tRASmin) as my 1st one has to make a Dual Channel?

ZeroPenguins Posted April 10, 2012 Report Share Posted April 10, 2012 Right now you're in single channel and to make it dual channel you just have to whack in another stick. But that is assuming that your other hardware supports dual channel. It doesn't matter about speed or latency, because if one RAM stick is faster and the other one is slower, the fast stick with underclock itself to the speed of the slower RAM stick.

Koby Posted April 10, 2012 Report Share Posted April 10, 2012 I find it best to have all your ram sticks matching in specs & brand if possible. Link to comment Share on other sites More sharing options...
ZeroPenguins Posted April 10, 2012 Report Share Posted April 10, 2012 ^I agree with that as well. But I do have some random DDR3 RAM sticks on my computer, they all run fine but at the slowest clock speed since my slowest RAM is bottlenecking it.

Mujklob Posted April 10, 2012 Report Share Posted April 10, 2012 If you're not mixing DIMM types, the short answer is that it will probably work. You could even grab a DDR2 1066Mhz and it would just be downclocked to 800Mhz. If you must do it, change the latency of the faster module to that of the slower one.Long answer: don't do it. Some motherboards are very senistive to mismatched RAM. Memory modules can break and motherboards can be fried. RAM is sold in kits for a reason and 4GB worth is dirt cheap.

Basudeb Posted April 11, 2012 Author Report Share Posted April 11, 2012 Thanks for all your help. I think my Mother Board support Dual Channel. I will grab 800Mhz for sure and tried to get the same module as Koby said, but it seems the module is unavailable, so other option is KVR800D2N6/2G don't know whether it will be available or not but specification are different as you can see. The error correction doesn't matter but what bother me is 256M x 72-bit 2GB while the first one was 256M x 64-bit (2GB).And thanks again. Link to comment Share on other sites More sharing options...
