The 'quad pumped' description suggests that four data bits can be transferred on each alternating current (A/C) cycle. Others are advertised to run with a 1333 FSB. For instance, the latest Qs advertise that they run on a 1600Mhz FSB. Intel uses the 'Quad Pumped' monicer to describe its Front side buss. Any speed grade above that won't hurt, other than to waste money for expenses - other than pizza!Īhhh, sorry to contradict, but it's a bit different than that. and that stuff is as cheap as dirt these days. It also will drive any ram installed to that 800 speed designated by DDR2-800. At a 400Mhz FSB, the CPU's 9X multi will drive a GO/Q66 right to it's max stable 3.6Ghz speed. The little ol Q66 has that sweet 9X multi. The P35 (X38X/P45/et al) was designed from the get-go to support the final Core2 CPU at a 400Mhz FSB.

It's really hardly worth the trouble from an empirical standpoint. This is great fun to play with, but will provide only subjective performance increases.

Most mobos have bios adjustments that allow users to increase the ram's speed by a multiplier. Generally mobos are defaulted to run ram at this DDR'd speed. The 1333 FSB systems only need DDR2-666 ram. So, these red hot QXXX9999XXX that run on the '1600' FSB - only need DDRX-800 ram. DDR2 vs DDR3 is simply planned obsolescence. The DDR'2' or DDR'3' only describe some minor engineering differences. The label the manufactures use to describe ram that is rated to run (or transfer) at this speed is called DDRX-666.

That ram MuSt be capable of operating at a DR (data rate) of 666Mb per second (2 bits x 333Mhz). Any ram that is installed on a system with a FSB running at 333Mhz will be required to transfer data at 2X that FSB speed. Ready for some arithametic? Here we go: A FSB advertised at '1333' is actually describing a 333Mhz FSB speed. It can transfer at Double the Data Rate of the front side buss speed. A FSB advertised at '1066' is actually running at 266Mhz.(266Mhz x 4bits per cycle = 1066Mb/Hz). A FSB advertised at '1333' is actually running at 333Mhz.(333Mhz x 4bits per cycle = 1333Mb/Hz). The Front Side buss is actually running at 400Mhz. So, if Intel advertises '1600' as their FSB number, they really mean that 1600Mb can be transfered each second via a FSB that is running at 400Mhz (400Mhz x 4bits per cycle = 1600Mb/Hz). A MegaHertz (MHz) is a million alternating current cycles per second. A single A/C cycle that occurs - over the time period of One Second - is called One Hertz (Hz), after Mr.

Ahhh, sorry to contradict, but it's a bit different than that.
