July 23, 201015 yr I have one of the official boards, the C2SEE, and this ram: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?Sku=C13-8220 Without setting anything in the BIOS, it booted fine, but when doing something intensive, it crashed. I went in the BIOS, and set the timings to the specs... then when I rebooted to run memtest, it showed the wrong timings. Sure enough, when I went back into the BIOS, it had saved my change from autodetect to manual, but had changed my 9-9-9-24 to 6-6-6-15! I tried again, and also changed the speed, rebooted... and now the computer won't turn on. I tried unplugging the AC cord and touching the clear CMOS jumper with a screwdriver like stated in the manual, but no change. I mean, it will turn on, as the lights and fans come on, but I get no video...
July 23, 201015 yr Author Got the BIOS to reset, wasn't using a big enough screwdriver... But it's still refused to boot if I change anything about the RAM... but the autodetected numbers are way too aggresive, causing me errors...
July 23, 201015 yr When it comes to RAM, Supermicro mobos are the finikiest pieces of.... well, you MUST use officially approved RAM. Also, have you tried the latest BIOS?
July 24, 201015 yr Author Just updated the BIOS... no luck still It's reading my 9-9-9-24/1333 RAM as 6-6-6-15/400 RAM I change the speed of the RAM in the bios up to 800 MHZ, but memtest still reports it as 400 MHZ... if I go any higher than 800 MHZ, it will fail to post. And if I change the timing from auto to anything, it fails to post.
July 24, 201015 yr Is the RAM on the officially approved list from Supermicro? If not, you are wasting time.
