I have a dell poweredge server and I've purchased 4- 8 gig memory sticks. I have ESXI server installed.  I have them placed in pairs.  Slots 1 and 2 and Slots 5 & 6 according to the specs.  However, when I boot the machine the bios is somehow disabling slots 5 & 6 so it's only reading 1/2 the memory. If you put the memory on once entire side of the slots its' not posting.

You would only install the modules in slots 5 & 6 if you have a second processor in your server.

Have you tried testing two modules at a time to ensure you don't have a faulty stick?

Also please list the part numbers of these memory modules to ensure that they're compatible with your server.

I have a 2nd processor in here.  Sorry I s hould have stated that.  It only reads either 5 & 6 or 1 & 2 but it will not read the entire memory.  ANd it's 64 bit..  There's not place in the bios to change this either.  They are dell memory modules.

Do you see the correct amount of memory in the BIOS? Can you also please post the part number of the memory modules anyway?

Check your documentation:

Memory must be installed in configurations of two, four, or eight DIMMs.

What are the specs of the memory? Was it Dell memory specifically for the 2970? What is your BIOS version?

As it turns out after  hours and hours of trying.  The memory is bad!  Thanks all for you input.

Glad you managed to find the issue. FYI I did suggest trying two sticks at a time to see if you had a faulty module or two. Were all four sticks bad or only some? How did you come to that conclusion also?

OMG I kept switching the memory back and forth and each time I did that, I finally realized that there were 2 pairs each time that were not working. Since the memory only works in pairs there was no way to just test a pair.  And because it kept switching from Dimm 1 & 2 to Dimm 5 & 6 that was bad, I knew it couldn't be a motherboard issue.  Then I tired the memory in another machine that takes the same memory and it failed.  That's how I knew!

Good thing you had that spare machine, otherwise you'd probably still be pulling your hair out now!
