when you use DDR2 ram and it says it runs at 800mhz does it really run at that speed? or is it actually 400mhz x 2?
It is actually 400mhz dumble pumped (ie. 400mhz X 2= 800mhz operating speed).....Edit: not really sure what u are asking but the memory does operate at 800 mhz speeds not 400mhz.
yeah but it says my RAM runs at 400mhz. i was thinking it says that because it's double pumped; like how it says my video card runs at 900mhz (3600mhz quad pumped)
Uhhh. according to math 400x2=800... So yeah...
running at 800mhz
and 400mhz x2 is exactly the same.
winna winna chicken dinna!!!
ha, to true!
DDR = Double Data Rate, Thus 800mhz RAM is really 400mhz at a multiplier of 2.
Edit: And for future reference, DDR3 IS NOT multiplied by 3 it is still DOUBLE data rate, 3 is just the genreration.
DOUBLE DATA RATE. DOUBLE. WTF is so hard to understand?
I'm still waiting for QDR
