no, just because it was free doesnt mean anything, if it wont recognise in your system, it cant be tested by any software program that would be available to you, for example, memtest86...either give it back or find someone who has that old of a system for them to try it in...I deal with alot of older systems with sdram and even 30 pin simmms and 72 pin simms(edo) they are VERY picky about ram, I have several sticks that are known to me to be good, that wont work in all of the systems, I even have a double height stick of sdram that is 4 clock and it works in most sdram setups, but its slower...but like i said earlier, it was free, so it doesnt mean it has to work or that you have to go to the ends of the earth to test it....32mb is not going to make any difference that you will be able to notice in that old of a system.....hell, if you insist on testing it, send it to me and I will send you back a few sticks of that old stuff to try, maybe one or two will work in your system...
