Problems
- Many of the memory tester motherboards on the "memory wall" are in bad shape, with bad slots, missing or loose RAM clips, etc.
- The mixture of motherboard types may no longer reflect the stream of incoming RAM, as well as Free Geek's priorities in testing it.
- We have pounds (literally) of SDRAM in Tardis, last I checked. A lot of SDRAM still comes in, but it is being used less and less in build (check this fact with George). We already reject PC100 and the SDRAM keeps piling up. There is too much to sell in the store and the asking price isn't great. Thus, we may actually want fewer SDRAM testers and possibly to start rejecting some or all 256MB sticks in favor of keeping 512MB sticks.
- DDR volume is increasing, as is DDR2.
State of the Motherboards, October 2009
At the beginning of October 2009, I took stock of the motherboards on the memory wall. Here are the ones that need replacement:
- 2 - DDR 4 slot
- 2 slots marginal
- 7 - SDRAM 3 slot
- 3 slots marginal!
- 9 - DDR 4 slot
- needs eventual replacement, runs all RAM as DDR266 and reports it incorrectly
- A - SDRAM 4 slot
- 1 slot BAD
- C - DDR 3 slot
- 2 slots marginal
- E - nonexistent
- candidate for immediate replacement since it doesn't exist
- G - SDRAM 4 slot
- 2 slots marginal
