Re: [PLUG] VMWare/Disk Cache Exceeding Physical Memory
|
The VMware mystery & saga ended tonight. I hate memory issues. Out of all computer
problems memory issues have got to be the worst.
Despite the fact that all my memory, good registered memory if you like Kingston had the same part number being KVR400S4R3/1G there were still issues. Surprise, surprise, surprise(in Gomer Pyle voice) you also have to check rev numbers. Those little white sticks at the other end of the DIMM.
My motherboard has 4 banks of 2 DIMM's each totaling 8 slots. Each bank of 2 DIMM's have to be the same. But bank to bank can be different sizes and ranks as well as chips.
Found 3 DIMM's I couldn't match up. Same part number but the rev numbers are as follows:
9965324-001.a00lf
9965324-006.a00
9965324-006-a00
The last 2 DIMM's listed above have different chips:
samsung 625
k4h510438c-zccc
samsung 637
k4h510438c-zccc
They also had different timing/buffer chips.
One by ICS
the other by TI
That's what I get for trying to get off cheap. Next time I'm spending the extra money and get them in matched pairs.
Memtest 2.01 finally had me look at the ram with a Microscope.
I'm just glad I finally found it.
