One of the RAM sticks in my old PC (AMD K6 233MHz) has just died, and I want to replace it. However, I dont know what speed it is. I know that it's 168-pin SO-DIMM SDRAM, but I have no idea what speed. I've looked in the BIOS, Memtest and in DSL (Damn Small Linux) but no luck. I've included a picture, just incase (excuse the low quality, taken on my phone ). This stick is 32MB.
