How DDR3 ecc reg PC3-8500R works with HP Z600 workstation?

First, you want to figure out if you have a version 1 Z600 or the later better faster version 2 Z600. The easiest way to do that is to go into BIOS and see what your boot block date is. The v2 has the later boot block date.

EDIT: This has to do with an upgrade to the motherboard, which allows use of faster processors and ECC buffered memory. Here is a quote from a later HP QuickSpecs ( HERE  ) for the Z600, under the Processors section:  "All B3-based systems will have a "1/30/09" date and C2-based systems will have a "01/07/10" date." Same concept for memory:

You can also look up the concept of triple channel memory which refers to a synergy that happens when the memory slots are best filled so that maximum speed and bandwidth of your memory is achieved. I personally like to fill all memory slots with identical ECC buffered (registered) memory... and it does make a difference. Finally you want to use memory that is rated for at least the max speed of your processor, and vice versa so that one does not slow down the other.

Then, you can review this post on my experiments finding what memory works in the Z600 v2, HERE . There are some valuable attachments I included at the bottom. Note that the PC3-8500 rated RAM is slow at 1066 MHz The Z600 v2 fastest processors can run at up to 1333 MHz (PC3-10600) and the memory I refer to is rated to run at up to 1866 MHz (PC3-14900). This is the fastest memory can ever run in the Zx20 v2 next generation workstations. However, the memory controller in the Z600 v2 will automatically run this memory at 1333MHz.

Thus, you end up with excellent fast ECC Buffered memory that can run in your Z600 v2 now and it also can run in a Z620 v2 if you upgrade your workstation later.

I have v2 HP z600  workstation.

Is the ram compatible or not?

Regardless of how fast your processor is the processor will be dragged down in speed to that second-to-slowest DDR3 speed.

But yes, that memory should be compatible with your Z600 v2.
