How would I get my bios open?
You won't need to open your BIOS. Just download 
this, open cpuz_x32, and click on the Memory tab in the window that appears. 
Under Timing, DRAM Frequency is the speed of the RAM. FSB:DRAM...ignore that. The timings are the next four values. If it appears as (for example): 
9.0 clocks
9 clocks
9 clocks
24 clocks
Your RAM timing is 9-9-9-24. 
Go to the SPD tab, and on the bottom (just above the buttoms) should be a column labelled Voltage. This is your RAM voltage.
