Solved Dual channel 2x4gb with 2x8gb Pairup Tags: Memory DDR3 RAM Geil Last response: February 18, 2013 10:18 AM in Memory Share cursedpillow February 17, 2013 9:21:35 AM Hi guys this is my first post I had 4pcs 4gb geil forsa enhanced ddr3-1600mhz pc-12800 1.5v cl9-9-9-28 ram. I currently had a thermaltake frio advanced cpu cooler installed (http://www.facebook.com/photo.php?fbid=329587697160240&...), had to remove the hi-profile geil forsa off the fourth dimm slot, also had to remove another from slot# 3 since my system somehow slowed down after removing the fourth. I plan on buying a low-profile crucial ballistix 16gb kit (2x8gb ddr3-1600mhz pc12800 1.5v cl9-9-9-24 ram) I have a gigabyte z77-ud3h mobo. I just want to ask if It is possible to pair up (2x8gb low-profile crucial ballistix ddr3-1600mhz pc12800 1.5v cl9-9-9-24 ram) with (2x4gb geil forsa enhanced ddr3-1600mhz pc-12800 1.5v cl9-9-9-28 ram) ?

Best solution knightdog56 a b } Memory February 17, 2013 2:14:51 PM Not a good idea to mix memory, just go with the crucial, 16Gb should be enough memory for a few more years. I am running with only 8Gb and use only around 40% max when playing games.
