https://community.hpe.com/t5/disk-enclosures/mod-20-mixed-memory/m-p/2459954#M374 Thanks Bob Inglis. I agree that mixing 60 and 70 nansecond memory may not be a good thing but does HP specifically say so and where. The reason I ask is that I have found in new memory pairs from HP have both 60 and 70' mixed and 1 part number. Perhaps this is a needed correction. Lacking any formal direction from HP I must assume that their mixing of memory pair's based on speed is supportable.<BR /><BR />Again Thanks for any info you can provide Tue, 31 Oct 2000 17:30:00 GMT Paul Allen_10 2000-10-31T17:30:00Z https://community.hpe.com/t5/disk-enclosures/mod-20-mixed-memory/m-p/2459954#M374 Thanks Bob Inglis.
