I recently bought 512MB of PC133 sdram (Â£29), to add to my current 256.
i put the new chip in @ Dimm1, and i put the old 256 in Dimm2.
when i started up, the 512 chip was not recognised in bios or windows.
i put the 256 in dimm3 and the 512 in dimm 1, and the the memory was recognised, but when i opened and
restarted windows, then windows wouldnt load ?!?
Somw Dos screens came up with a few paragraphs of strange jargan that i hvae never seen before.when i restarted i found my HDD
wasnt being recognised, so i resatred again. then i got a high pitched beebing from my case speaker, and nothing would come up
- not the dos screens , not bios nothing - just a 100% blank screen.
finally normality was returned to when i put the old memory in dimm1.
it would be obvious that the memory was at fault, but i dont know why it did work for 1 of my boot ups??
My mobo says it only takes 3.3V memory … how can i tell what voltage [or whatever v stands for] my memory is??
