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.
- 1 - RAMBUS 4 slot ; OK
- 2 - DDR 4 slot
- 2 slots marginal; replace with DDR 4 slot
- 3 - DDR 2 slot, SDRAM 2 slot
- OK
- 4 - DDR 4 slot
- OK
- 5 - DDR 4 slot
- OK
- 6 - DDR2 4 slot
- OK
- 7 - SDRAM 3 slot
- 3 slots marginal! replace with DDR2 4 slot
- 8 - DDR 2 slot, DDR2 2 slot
- OK
- 9 - DDR 4 slot
- needs eventual replacement, runs all RAM as DDR266 and reports it incorrectly; replace with DDR2 4 slot
- A - SDRAM 4 slot
- 1 slot BAD; replace with 4 slot SDRAM
- B - DDR2 4 slot
- OK
- C - DDR 3 slot
- 2 slots marginal; replace with DDR 4 slot
- D - DDR 2 slot, SDRAM 2 slot
- OK
- E - nonexistent
- candidate for immediate replacement since it doesn't exist; replace with DDR3 board
- F - DDR 4 slot
- OK
- G - SDRAM 4 slot
- 2 slots marginal; replace with 4 slot SDRAM
Summary
