Thanks very much for this really informative guide...it's a great help. Just a couple of general questions though:
I've had some bad experiences on my older motherboard when trying to set FSB to values other than the standard ones (100/133/166/200) due to having a divider for the PCI rather than an option to lock it to a certain frequency, which meant that the PCI bus was running too fast or too slow, and I got data corruption on my hard drives. I now have an Asus A7N8X Deluxe, which does have an AGP lock. Am I right in thinking I'll risk no trouble of this kind if I just set the AGP to 66 MHz, and then play around with increasing FSB to my heart's content?
At the moment, I've been conservative about FSB, so I've set it to 200 (which somewhat surprisingly works fine - the default for my CPU is 133) and lowered the CPU multiplier.
It's a TBred A 2000+, which runs at 133*12.5 = 1666 by default. Without any increase in VCore, the best I could get is 200*8.5 = 1700 (completely stable). I've put VCore up by 0.75 and am now getting 200*9.0 completely stable. I haven't tried 200*9.5 yet. Would I be better off seeing if I could push the FSB higher first? Is this safe as long as I lock the AGP? Do I need to lock to PCI too, or is that just fixed wrt the AGP?
Will I need to overvolt the Northbridge or RAM for higher FSB? How much is safe (RAM is 1x512 MB Twinmos PC3200, 2.6V default). How much can I expect from this mobo/CPU combination? I'm guessing I want to be keeping the RAM in synch with FSB by the way, right?
As you can see I'm fairly new to all this, so thanks v much for any help.
