Hi, I'm thinking of upgrading the GPU in my Z820 used for Video production (Resolve, Premiere, etc.). I have a Z820 that I purchased in 2012 with a single Xeon E5-2670 2.60 20MB, 1600 8C , 32 GB RAM, in a 1125W chassis, and an NVIDIA Quadro 4000, running Windows 7 Ultimate (x64). I'm considering upgrade to either the NVIDIA GTX 1080 Ti (if I can find one) or the RTX 2080 Ti to replace the Q4000. I would llike to know if anyone is running either of these cards in their Z820s and if they've had any compatibility or fit issues.
Also, in the 2012 Quick Specs, the only option for 32GB was this option:
32GB DDR3-1600 ECC Load Reduced (LR) RAM A2Z53AA
and my receipt lists the following:
32GB DDR3-1600 (4x8GB) 1CPU Registered RAM (Supported only with Single Processor.)
In the Quick Specs, the following also appears:
NOTE: You cannot intermix registered and unbuffered DIMMs. The system will not work.
NOTE: You cannot intermix LR DIMMs with either registered or unbuffered DIMMs. The
system will not work.
I'm confused because it also lists the memory as LR, but the receipt lists it as Registered. Does anyone know if LR memory is in fact Registered (just a special class), even if it can't be mixed with non-LR Registered DIMMs? I just want to have verification of what kind of RAM I have installed (4x8GB DIMMs) in case I need to upgrade.
Any input, advice, or comment would be appreciated.
Cheers,
Shane
