can i mix ram capacities in my server?

[Ashleyyyy]

i've got 3x2GB pc3-10600R, can i mix that together with 6x4GB PC3-10600R? will that work?

 

and the ram i have has 9-11-B0 on the label and the other ram has 9-10-B0... what does that mean?

Yes, as long as both brands of RAM are supported by the motherboard specs, than you can use different RAM in a Server, however all RAM will only work as fast speed as the slowest speed module in there.

And if you can't find the motherboard specs on supported RAM vendors, just pop them in and see if it boots, if it does, you're golden, if not, take them back out, it won't cause any Damage, it'll just give a Memory Error at boot if it's not functioning and won't allow the computer to continue post until the RAM is removed.

the memory i want to put in is the same brand as that is in there now.

will work fine. just remember that whatever RAM chip is the slowest one. That is the speed the mobo will max at.

Yeah but even the same brands can be iffy, for instance in mine it supports a bunch of random 2GB Hynix modules but only two very specific 4GB modules. You gotta match the exact model numbers. But, like I said, you can mix and match any supported RAM, and there's two ways to find out, either look up the OE motherboard spec sheet, see if the model number is listed for what you have, or, just put them in and see if it works, there won't be any damage by running an unsupported memory type in the motherboard, if it doesn't work, it won't post fully, and you'll know it didn't work, so you can just take them back out.

It's honestly easier to just put them in and see if they work than it is to look through the entire supported memory sheet, there's hundreds of modules you gotta sort through to find your exact model and if it's not even there, you just wasted like an hour looking over the PDF

this is my server ram compatibility list: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c01727710

They don't specify what modules are supported so the only way to know for sure is to just try putting them in and see if it boots.

Just make sure you put them in the right memory channels for the right CPU like it says on that page, you said you had 3x2gb now, which means there should be one 2gb module in Channel 1 DIMM 3, Channel 2 DIMM 6, and Channel 3 DIMM 9

So put the 4GB modules in Channel 1 DIMM 1 and 2, Channel 2 DIMM 4 and 5, Channel 3 DIMM 7 and 8

I'm also assuming you only have one CPU in there as well, otherwise you need to allocate the memory to the correct channels per CPU, but having 3x2GB doesn't really make sense for dual CPU which is why I'm assuming you only have a single CPU in there right now.

i have 2 cpu's. i had 5x2GB but i needed to take that out because those are not registered dimms.. so i put the registered dimms i had back in...

@bANONYMOUS i'm getting new ram for it because i also got 2 Xeon X5650's for it. i want to use it as my main pc..
