The Truth about Dividers and Multipliers and why My fourth graderknows more about OverClocking than me...
I have a question that roots from a post in another group...
How, What... Could anyone please explain this in an OverClocking fashion?? Like, what is this about dividers, multipliers, CAS, DRAM timings and such and how to understand the people on the OverClocking NewsGroups??? Thanks In Advance ~7~ --Snail """Woobie" wrote in message ... Try this: Go into bios and where it has settings for your cpu, there should be a "/#" called the "divider." I believe it sets ratio speeds for the clock multiplier. Change it to "/5." Divider needs to be "4" NOT 5 133 x 4 = 533 multiplier of 23 to get 3ghz"" |

I would also like to know just how clock settings for CPU, DDR, AGP, PCI as
well as memory timing all affect the performance of my PC... Especially since my memory is PC4200 (DDR533) stuff.

Divider needs to be "4" NOT 5 Ok multipliers, multiplier is based off your computers front side bus. http://www.tutorgig.com/encyclopedia...Front_side_bus You use the multiplier times the front side bus to get your processors speed. Now here below they are talking about a pentium 4 processor (I assume). Because the front side bus of some pentiums are "Quad pumped" meaning the original FSB (Front side bus) X 4 = actual FSB. THen you take your actual FSB and put it to a multiplier to get your CPU speed. Now the thing to remember is that the FSB shuttles Data to and from the processor. So having a 3ghz processor and a 100Mhz FSB wouldn't work, you wouldn't be able to shuttle data fast enough! So as processors get faster so do FSB speeds. 133 x 4 = 533 multiplier of 23 to get 3ghz"" Now CAS latency affects Ram and Data retrival speeds from it. SO ram with a high cas latency 3ns is slow, where as a 2ns ram is much faster, which means a lower CAS number = more money, but better performance. DRAM timings have to do with how data is retieved form the RAM as well, the motherboard typicaly needs to know what the CAS timing is on the ram, the charge delays and etc. Think about it in the terms of a car, you can slpa one together and it will run but not at its best. Instead you have to get the timing right, so that everything works in harmony. A computer is much the same, the closer to the actual specs you are when timing your ram, the better the performance. Now overclocking comes of the fact, that most computer hardware is released at specs that run it at less than its peak efficiency. Why you ask? Take processors for instance. Hardocp.com ran a test where they Overclocked 4 of the same processors, not all could go as high as the next one, because of manufacturing defects, age...etc who knows exactly. So the companies release a spec at the fast possible speed that these parts will run stable. This is why OCing can cause system stability problems, but if done correctly will give you a faster machine than what you paid for. I myself have an Athlon Xp 2500+ that is OC'ed to a 3200+ and it runs fine. Hope this helps. Chris |
