05-02-2016, 10:07 AM #1Right now things are really mixed up. I'm switching from Vengeance RGB to a new single stick model and keeping the old one. I'm using slots 2,3,4 which some forums suggest is okay. The problem is that when I try different combinations—like putting in slots 2,3,4 or 1,2,4—it won't boot. Then I tried slot 2,4 but paired it with the old stick and the new one, and it worked! But when I install slots 2,3,4 it still doesn't boot, and the RAM is flashing red. Anyone have any ideas? I'm using a screwdriver on a BIOS that only has 2-pin connections.
You can upgrade to a different RAM kit without any problems if you follow the correct steps. The presence of a step 3 stick indicates a specific configuration or compatibility requirement, but it doesn’t prevent you from purchasing another Corsair kit. Just ensure your new RAM matches the specifications and you’re ready to install it properly.
hrug: Appreciate you helping.It seems the setup process was similar to what was described with 386. To fill the 64-bit memory bus you needed to use either 4 or 8 slots, or skip the POST. My 771 server also had issues—installing six sticks at a time was necessary for it to function properly. There are 12 total slots, with six per CPU. Each CPU has three channels, but only two can be used at once due to the IMC limitation. I’m not sure why this setup is the case.
AMD systems typically demand more memory, usually 32GB or 64GB. A quick tip: sizes like 12, 24, 48, and 96GB fit LGA 1366 slots, which have three channels per CPU, making your RAM amounts multiples of three when all channels are used with dual processors. Early consumer boards generally offer 2 or 4 slots, so it's wise to plan your memory across two channels or four slots.
