Closed Combining 2x2GB with a 4GB RAM stick Tags: Chipsets RAM Memory Motherboards Last response: February 2, 2013 11:19 PM in Motherboards Share chanuka February 1, 2013 10:40:11 PM I need to upgrade my RAM. I can't find any memory kits in my country at this time so i want to go for a single 4GB ram stick. My current specs Intel DH55HC - http://downloadmirror.intel.com/18506/eng/DH55HC_Produc... Core i5 760 2x2GB DDR3 1333MHz Kingston I'm trying to get a new 4GB stick to make it 8GB. It's also kingston and the speeds are the same Can i use the DIMM 1 slot A for this ram ? DIMM 0 A&B is with the 2GB pair Will it run in dual channel configuration ? Is it okey to combine 2 sizes of memory ? My motherboard memory spec sheet says that it supports 16 GB maximum total system memory (with 2 Gb memory technology). What does that mean ? http://www.intel.com/support/motherboards/desktop/dh55h...

DIMM 0 A&B is with the 2GB pair You can install that module into the DIMM, but it would not be recommended. The recommended practice is to install RAM modules in kits, such as the kit you have in DIMM 0. chanuka said:Will it run in dual channel configuration ? To achieve Dual Channel mode, the following conditions must be met: Matched DIMM configuration in each channel Same capacity (128MB, 256MB, 512MB, etc.) Matched in both Channel A and Channel B memory channels OR Populate symmetrical memory slots (Slot 0 or Slot 1) Configurations that do not match the above conditions will revert to Single Channel mode. The following conditions do not need to be met: Same brand Same timing specifications Same DDR speed Memory channel speed is determined by the slowest DIMM module populated in the system. chanuka said: Is it okey to combine 2 sizes of memory ? You can, but you'll be limited to the lower specs of the combination. chanuka said: My motherboard memory spec sheet says that it supports 16 GB maximum total system memory (with 2 Gb memory technology).

Thank you in Advance It means that your mobo can support 4GB single sticks per slot. chanuka February 2, 2013 10:56:17 AM Best answer selected by chanuka. Can't find your answer ? Ask !
