Closed Mixing RAM of two different timings Tags: Memory DDR3 RAM Last response: March 9, 2012 2:46 AM in Memory Share tbell February 22, 2012 5:19:37 PM I have the following. 2 x Memory Module - 4GB, PC3-10666, DDR3-1333MHz, 9-9-9-24 http://www.tigerdirect.com/applications/searchtools/ite... I want to add the following. 2 x Memory Module - 4GB, PC3-10666, DDR3-1333MHz, 9-9-9-27 http://www.tigerdirect.com/applications/searchtools/ite... Does the timing (24 vs 27) difference matter? More about : mixing ram timings price_th February 22, 2012 5:25:49 PM It should work. It may just cause the ram to run at the slower timing. hotthree February 22, 2012 5:32:01 PM Two different types of ram = Bad (it is well known that you need to stay consistant with ram. Two different timings = bad (can cause stability issues etc) The main concern is Voltage which both have 1.5v rating...if these were different you could fry the lesser rated. It might work, but it also can be unstable. Your risk. I would never do it if it was my gear.

It used to be a non-issue but as DDR has gotten faster and faster, tolerances have all but disappeared. You can get lucky with it but if you have any plans for overclocking, forget it. Overclocking and mixed memory are almost a certain fail.

I would just save and get a 8gb kit, or buy 2 4gb kits. tbell February 23, 2012 1:22:51 PM Thanks to ALL for the advice. Saved me money and hassle.
