    PM1725a Availability or Comparible Unit?

    Thanks for the suggestion. I hadn't heard of the 4608 - seems to just be a high capacity 4600? Optane would certainly be the fastest, but I think it's above my target ceiling in performance and price/performance. Luckily I'm not looking to stuff a server full of them - my plan was to RAID0...

    PM1725a Availability or Comparible Unit?

    Hi, I bit the bullet and tried to order 2 HHHL PM1725a 3.2TB drives, specifically part # MZPLL3T2HMLS, for a bioinformatic computational server. We're looking for fast read/write with high endurance. Unfortunately, everyone seems to be out of stock of the PM1725a. I know the 1725s have been...

    Dell EPYC R7425 DIMM Operating Speed

    Hi All, Just purchased our laboratory a brand new EPYC server from Dell - A R7425 chassis with dual EPYC 7451. I also purchased 8x32 GB DIMM modules rated at 2666. The BIOS is only recognizing them as 2400. In looking through the manual...
