I was putting a socket on a motherboard for a RTC and when I was going over the manual for the jumper settings there was one about setting the SRAM type for 3.3 volts or 5 volts, the manual says

set according to SRAM used 3.3 v is 3.3 volt in and out, mixed mode is 5v in and 3.3 v out

Ive got two sticks of 8mb EDO 70 ns 72 pin but other than looking at them I cant tell what voltage they are like all my other sticks in my horded box, the motherboard is an ASUS PCI/I-P54SP4 rev 1.4. I looked up "LGS GM7IC4403CJ70" but google didnt come up with much except ebay and the guy there selling his says they are 5V but if I want to look up another set of sticks how do I search if they are 3.3v or 5v?
