NOW, in the 4 and 2 things that they do a 1066mhz processor sends data 266mhz faster then the 800mhz ram can send data to the processor.
The graphics cards work the same way as ram with sending two at 800mhz if the memory clock is 1600mhz.
What exactly are the 2 and the 4 called, I want to know the name rather then just 2 and 4 lol.
also, what is the difference in ddr, ddr2, ddr3? are they just spolit into categories depending on speed?
Another also, what other bus's are there other then fsb. what do they do?
1066 FSB would be effectively 266.5 and 800 RAM would be effectively 400. The ram would be running faster than the FSB, not the other way around.
The 4 pertaining to FSB is called quad pumped, and it is what intel uses.
the 2 pertaining to the RAM is from the Double Rate Data, DDR. I shoulda been clearer on my earlier post about DDR2, the DDR is what makes it double, not the 2.
DDR DDR2 DDR3 are just different technologies.
DDR3 is going to have increased frequencies and thus higher bandwidth than DDR2, but at the cost of higher latencies.
And i think i twas the same deal with DDR2 and DDR, although i was never into PCs around the time of DDR so i'm not 100% sure on DDR2 vs DDR.
Not sure about buses, i'm not that technical. And about GFX cards, they don't work the exact same way as a your CPU RAM and FSB... Not to keen on exactly how GFX cards work when it comes down to the way the parts interact.
