Strictly speaking.. Mhz means a million cycles per second.. So faster would be 533.. Cause obviously 533 is more than 66. And yes.. it is that simple. larger numbers means less time between cycles and less time means faster.
If your motherboard can support 533 Mhz then no, not at all. If it only supports 400 mhz then yes If your a guru and want to run 533 mhz then overclock... But it think if you are running your ram at 533 as an upgrade, i think time for a new computer buddy :)
It's in relation to speed. 533 is slower than 800.
1066 MHz, 800 MHz, 533 MHz, and 400 MHz
2.
250 mhz fo sure...
Common speeds for the system bus (motherboard speed) are 1066 MHz, 800 MHz, 533 MHz, and 400 MHz.
The three speeds of the most popular motherboards currently available on the market are, 1066 Mhz, 800 Mhz, and 533 Mhz
Personaly, i have to R/C cars that are 27 MHZ and 49 MHZ and my 49 MHZ goes faster than the 27 MHZ. but the 27 MHZ has much more control than the 49 MHZ.
1.10 MHz is tremendously slower than 750 MHz. If you meant 1.10 GHz vs. 750 MHz, then yes, 1.10 GHz is faster than 750 MHz.
Is a memory of 256 Mb
No. They are different generations of DDR.
No, keep the new stick to 533, you can go 666 or 667 but no higher. it will work @ the lowes speed of all, and will be 15-25 % slower than matching speed.
