Hi,\n\nI was using my Abit aw8-max board with 2x1 GB Kingston(KVR667D2N5/1G) without any issue for a long time. Because of the max 8 GB support ı was planning to upgrade it higher ram capacities.\n\n1 - I tried 4x1 GB Kingston(KVR667D2N5/1G) but didn't work. After booting on the screen only see 1 core CPU and stuck at this stage. The error code was 4E on the motherboard led screen.\n2 - I ordered 4x2 GB Elpida(EBE21EE8ACWA-8G-E). I installed 1x2 GB of it and it works fine without any issue. Afterward, installed the second stick as 2x2 GB. At this time I had the same problem as Post Code 4E.\n\nI did many searches on the web and read several articles but they didn't help me to overcome the problem. \n\nI also uploaded hwinfo output of my computer with current hardware details. \n\nThanks in advance for your help.
