Hi
Currently running a Dell Precision with a Quadro 6000 and Tesla C2075.
Both cards have 6000MB of DDR5 VRAM.
However GPU-Z shows only 5376MB per card.
Any particular reason for this difference?
Thanks for your help.

Yes ECC memory. Would that make a difference? Thanks,
*Note: With ECC on, a portion of the dedicated memory is used for ECC bits, so the available user memory is reduced by 12.5%.
(e.g. 6.144 GB total memory yields 5.376 GB of user available memory.)

That could explain it for the Quadro 6000, but ECC is disabled for the C2075.

Thanks for that. Just shows you are never to old to learn something new :--))
