Hi all, I have two sticks of 32Mb 72pin EDO Ram but I dont know the speed of them I know EDO are usually 60ns or 70ns and my 2 sticks are a matched pair and have chips on both sides. should I use something like memtest 86+ or does the numbers on the chips tell me if thats true I will post some pictures of them to show the numbers.
The last one or two digits (sometimes separated by "-") of the chips' model number generally designates the speed. Here are some examples:

GA-6VTXE PIII 1.4+512MB
Geforce4 Ti 4200 64MB
Diamond Monster 3D 12MB SLI
SB AWE64 PNP+32MB
120GB IDE Samsung/80GB IDE Seagate/146GB SCSI Compaq/73GB SCSI IBM
Adaptec AHA29160
3com 3C905B-TX
Gotek+CF Reader
MSDOS 6.22+Win 3.11/95 OSR2.1/98SE/ME/2000
I had to clean my two sticks from stickers and some sort of pen I have included two pictures but it is hard to get all the chips writing so I have writen everything down:
