Can i enjoy two different speeds of bump at one and the same time?

my motherboard can use both pc3200 and pc4000 can i hold one pc3200 and one pc4000 or should they be the same

Can i enjoy two different speeds of bump at one and the same time?

They should be equal if at all possible, because what will arise is the motherboard will force both pieces of memory to run at the slowest speed. So if you have PC4000 and PC3200, the MB will run both at the PC3200 speed.
Usually it will run at the speed of the slowest one, so even if you enjoy the faster one in, it will operate at impossible to tell apart speed as the slow one.
u cant run ddr1 and ddr2 together ... if the 4000 is ddr1 it should be fine and if ur system only supports up to 3200 next the 4000 will just run at the slower speed ..
The genuine question here is can you possibly be anymore of a bore?
Yes, you can use different speeds of RAM chips in your computer, but they will work at the lowest speed (in your covering, the speed of PC3200).
YES. BUT BIOS will always synchronize them to that w/ the lowest speed and untouchable timings.
