Using UDIMM and RDIMM RAM in the same computer

Hello!

I am a video-editor - I have a Dell T3600 Precision Workstation. I've always liked this computer; however, I have recently been getting the error message 'low on memory' when rendering large files. So I thought I'd look into purchasing some more memory for my computer.

My computer has the capacity to hold 64 GB of RAM memory. Currently, I only have 8GB of UDIMM memory (my receipt said I have 8GB, DDR3 UDIMM Memory, 1600MHz, Non-ECC). However, Dell will only let me upgrade my computer with RDIMM Ram (they were trying to sell me 8 GB Certified Replacement Memory Module, 2Rx4 RDIMM 1333MHz LV). According to the Dell customer service agent, there would be NO conflict if I upgraded my workstation to RDIMM RAM (meaning I could have UDIMM RAM as well as RDIMM Ram in my computer at the same time without any conflict). However, is this really true? Would it harm my computer at all? Or would it even make it any faster?

Any help you guys could provide would be much appreciated!

Thanks so much!
Tony
 
Crucial chat should tell you. Use their scan feature, which should offer compatible options.
 
The T3600 is an LGA 2011 based board. The Xeon chip it sounds like you have in it will work fine with standard UDIMMs. Absolutely no reason to pay the Dell "tax" for RAM.

I would also not mix UDIMMs and RDIMMs.

The RAM it came with is probably Hynix or Kingston. You can tell by the sticker on the RAM itself.

Adding 1333Mhz RAM to your system would make the current RAM slow down to 1333Mhz as well. I also would not trust running two different speed rated sticks in the same machine. I have tried it before, and it is very iffy as to whether your system will actually be stable or not.

It would probably be easiest to just buy 4 sticks or a Quad channel kit (4x4GB or 4x8GB) of DDR3-1600, 1.35v or 1.5v depending on how much you want to upgrade to.

Right now, I am guessing you have 2x4GB sticks. If this is the case, you are only running in dual channel mode. Going up to quad channel will give you a nice bump in speed, especially for what you are doing.

Pretty much any of the standard kits from any of the big name companies will work just fine.

Yes, I do actually have experience with this specific model as I have a few of them where I work.
 
Everyone, thank you so much for your help! The information you provided me with helped me make the decision to just get rid of my UDIMM and upgrade to RDIMM; looks like you're right, you definitely can't mix UDIMMs with RDIMMs, and my computer can't hold anymore UDIMMs (it only has 4 available slots, and they're currently taken up by 4x2GB of UDIMMs). Again, thank you so much, I sincerely appreciate your help!;)
