Hello, my current configuration has my XP barton 2600+ running at 1.9Ghz and 333 FSB and my pc 3200 ram running at C2 latencies, also at 333mhz. Now I have a few questions about the compliance between the RAM and Processor.
1. Do I have to run my FSB and RAM at the same speeds? (for example: running my Barton's FSB at 400 and my RAM at 400)
2. Does this yield better performance than not syncronizing them? (running FSB at 333 and RAM at 400, or vice versa?)Now I have some questions about OC'ing my processor...
A Barton 2600+ has 333mhz base FSB
1. Will I be able to raise my FSB to 400, if my motherboard supports it? Will this lead to noticeable/significant increases in heat?
2. After I have raised my FSB to 400, what do I do to my multiplier to yield faster processor speed, while maintaining stability? (+/-?) For example, I want to have xp 3200+ speeds...I want to avoid upping my voltage as much as possible.
3. I have read some threads where 200fsb wasnt even attainable on the Barton 2600+, why not?Thanks for your time, it is appreciated, no doubt!

1. No, but it's a good idea
2. Yes1. Yes. It could, generally, Mhz=heat
2. You do whatever you combination will allow
3. That would be a hardware issue; i.e. crappy motherboard, memory...
You'll get more answers too.Skip

Thanks skip. I have read some threads where people are talking about having to lower the multiplier when raising the FSB, or Lowering the FSB when raising the multiplier?? can someone give me details on this?

Very concise answers, skip.
Chad:
Given (or default)
24 x 100 = 2400
PCI = 33 mhz
AGP = 66 mhz
Memory = 100 mhzChange in FSB
18 x 133 = 2394 (almost the same as default)
PCI = 33 x 1.33 = 44 mhz
AGP = 66 x 1.33 = 88 mhz
Memory = 100 x 1.33 = 133 mhzConclusion: change FSB would also change the PCI, AGP and memory speed. (if there is no PCI/AGP lock function).
The increase speed may not be handled well by graphic card, hard drive, modem, PCI TV tuner and memory etc. Or the chipset wouldn't be able to handle the higher FSB speed. But, when they do, you gain performance from all the components.The trick is to find the best of both worlds. Bear in mind, Intel and AMD are not run by stupid people. Overclockers are finding the flaws in their marketing scheme of "things" and capitalize on it, of course the high yield from manufacturing technology play an important role.

im somewhat confused, you saying that as the fsb rises, so does the speed of the agp, and pci slots? I think i heard somewhere that it isnt a good thing when that happens??
Would there be an option to lock my AGP and PCI speeds so that they are not multiplied as well? Where?

Raising the fsb does raise the agp and pci unless you have a board that has that locked, also it would depend on the dividers your board has if it isnt locked. You wanna keep the pci speed below 39 so your hard drive doesnt get curupted, for my one machine which doesnt have those locked i use a prog called overclock calulator.The way i have done it is to lower your mulits and slowly raise the fsb.

Hey Chad,
Once you figure out what is an optimal state for your system, would you mind posting it and the basics of what you did?
I have a friend with a barton 2600+ who I know will benefit. Thanks

Sorry, but I think that the 2600 bartons are locked after week 39....Hope I didnt get one. We will see, im making a post to confirm this.

Reading though these posts it doesn't look like anyones given you a straight answer chad. Let me help...
Running your fsb/dram asynchronously wont help you in this situation, for example running your cpu at 333 and the ram at its top speed of 400 will give you an async ratio of 4/5. For both stability and speed its best to down clock your ram to 333 to run in sync (1:1). Running in async mode can cause system slowdowns due to waiting times. RAM which runs faster than the CPU can supply the data to the CPU faster than the CPU can recieve it.
As for the idea of over o/cing, if you can o/c your processor to run at 400fsb you will massively increase both speed and efficiency. Your only problem might be is if your multiplier is locked, as most are nowadays. Try setting your ram to 400 and slowly increase your fsb, trying to get up to 400fsb. Keep an eye on the heat increase, but bartons are one of the best cpu's for o/cing so you should be ok.
Hope this helps.
