minuzle Posted December 4, 2020 Share Posted December 4, 2020 I just purchased a used Supermicro X9DRL-iF that came with two E5-2690 v2's. It has 16gb of ram (they didn't say the speed I assume DDR3 1866). I have a 20 drive array with 2x 512gb SSD's in a cache pool. Will 16 GB be enough or should I look at adding some more? I don't run any VM's I do have a few dockers though (medusa, pihole, plex, sab, tautulli). Thank you in advance minuzle Quote Link to comment
SeeGee Posted December 4, 2020 Share Posted December 4, 2020 Those CPUs support a maximum 2133mhz ECC. 16gb "should" be enough, but I might suggest another 16gb if you're going to be running a bunch of containers. Those are nice CPUs. I have a pair myself. How many sticks do you have? I'm assuming 4x4gb?The more sticks you have, the slower the ram runs. I think once you have more than 2 sticks per channel is when it starts to step down. Quote Link to comment

I think once you have more than 2 sticks per channel is when it starts to step down. It is 2x8gb, I did just order some 1866 off ebay (4x8gb). I'm not sure what the clock is on the ram coming with the board as the listing description didn't say, I was more in it for the motherboard and CPU's. My guess is if I mix the ram they will be throttled down to whatever the slowest speed is. Quote Link to comment
SeeGee Posted December 4, 2020 Share Posted December 4, 2020 Just realized that you have the v2, not v3. I believe that you may be right about the 1866mhz ram. My bad. Quote Link to comment
SeeGee Posted December 4, 2020 Share Posted December 4, 2020 Wait, only 2 sticks total? That implies that it's only running single channel per cpu. Additional sticks will help you in more ways than one! Definitely research the cpu/Motherboard and investigate the optimal configuration. My dual Xeon e5-2690 v3 supermicro x10 system needs 8 sticks for full quad channel support on both CPUs. https://www.techpowerup.com/cpu-specs/xeon-e5-2690-v2.c1667This lists your cpu as supporting quad channel ddr3, up to 1866. 8 identical sticks (4 per cpu) would be needed for quad, 2 per cpu gives you dual, and of course, one per cpu gives you single channel.Your Motherboard manual from supermicro would have a concise chart of what slots to use and supported configurations. Take a look memory configuration there Quote Link to comment

I will probably just use the 4 I just purchased now then, I would have purchased more but he only had 4 available. Do you feel like 2 per cpu will be enough? Quote Link to comment
SeeGee Posted December 4, 2020 Share Posted December 4, 2020 Yeah, if you use 2 per cpu then it'll run dual channel with 32gigs should be more than ample for your uses. Worry about more when you need more. Just remember to check the manual for which slots to put them in. 1 Quote Link to comment
