VRAM SIMMs: Differentiating Between 256k and 512k (11/94)


Is there any method of identifying a 256k and 512k VRAM SIMM? There are no distinguishing numbers on the chips themselves which help to identify the density.

The only way to differentiate VRAM SIMMs is by the number of individual chips on the SIMM itself. The 256K VRAM SIMM has two (2) 40-pin ICs, and the 512K VRAM SIMM has 4 (four) 28-pin ICs.

Do keep in mind that VRAM SIMMs comes in two different speeds, 80ns and 100ns.
