Hi Valerys,
The combination would not make much difference but you would lose the performance of the 1333MHz RAM sticks. They would be running at a degraded performance or at the speeds of 1066MHz. Apart from that, there should not be any system crashes.
Thanks,
Ram.
Thank you,
How much this performance loss?
Hi,
The 1333 stick runs at 21Gb/s and the 1066 stick runs at 17Gb/s. So, there's a 4 Gb/s loss on each stick used. You may calculate accordingly depending on the number of RAM sticks used.
Regards,
Ram.
I don't think that you will notice the difference...
I would prefer to have MORE memory than FASTER memory
The OP wouldn't notice the difference, but the customer could. Remember there might be memory-intensive applications (mainly Databases or SAP) running on top of the ESXi host where every millisecond when moving large data-sets could matter.
But if the VMs hosted don't need large memory throughput at all (file servers, dhcp, dc, some app... hell almost everything else except databases :smileygrin:) then I agree, bigger is better
