OC'ing CPU's and RAM

[/i][/b]

Your CPU runs @ a true clock of 200MHz (I call it the Crystal Clock, it gets much more complicated but for this purpose, I will stick to the basics) and there is then the multiplier in the CPU (again, gets real complex and such but I will keep basic) that allows it to run faster, such as 200Mhz x10 Multi = 2000Mhz (2Ghz). 1:1 means that your RAM and FSB (Crystal Clock) both run @ the same speed, e.g., 200MHz for DDR400, 250MHz for DDR450, etc. There is a RAM divider in most motherboards that will let you run an Async FSB to RAM or vice versa sometimes, such as a Clock of 200Mhz and RAM of 166MHz so you can OC the CPU further if your RAM won't OC as much.

Changing your timings isn't really overclocking, it is in a sense, but all it requires usually is increase in voltage to the RAM Modules (done in the BIOS). Overclocking RAM can be Async to CPU and therefore means you would increase Memory Bandwidth, but keep CPU speed the same. Now, it gets different when talking about an Athlon 64 and a Pentium 4, the Athlon 64 benefits from all Memory Bandwidth improvements due to the Onboard Memory Controller, the P4 has a 800Mhz FSB that can only handle DDR400 (6.4GB/s) and therefore means you must OC the CPU in order to take full advantage of overclocked RAM.

I did write a thread about things like this and such, here's the link: http://forumz.tomshardware.com/hardware/modules.php?nam...

What, INTEL? I don't like 'em either, just got my AMD Opteron 170/ 939, time to go to town! :twisted: I like a company that uses it's brains, not just the 'brute force' approach Intel does...

***As an aside, I JUST got my CPU from MonCom after waiting 2 weeks!!! This pretty well pissed me off, considering this is supposed to be a major vendor of computer systems and components. I just used 5 days of vacation time to sit on my ass and wonder what the hold up was while being spoon-fed one ** lie after another... Will stick with New@@@ from now on...***

Oh geez, that's a bummer man!

Good luck with that opteron man. I have the 165 and I love it. After being an Intel enthusiast for so long, it's a nice change of pace  

nice little article about ram and cpu oc but u said that 250mhz ram=ddr450 but it is really 250mhz ram=ddr500.
