VCore increase to reach 1.6+

[popadel]

Q1:
How to increase VCore to past 1.85 ~ 1.92
I want to reach 1.6G, but " I NEED MORE POWER CAPTIN!"
I dont want to drill into my Mobo at all.

Any takers?

Q2:
At what FSB frequency past 133 will the PCI = 33 and AGP = 67 again? I would like to try the 266 method but my board only allows me 250X2 = 500 instead of 532.

Answer 1:
I'm not familiar with your board, but I can tell you that although you won't need to 'drill into' your board, you will need to perform a volt mod. This involves soldering a resistor between the voltage feedback pin of the IC controlling the voltage, and ground. This is very tricky and not to be attempted if you have no previous soldering experience - unless of course you don't mind replacing your mobo if it all goes wrong! If you really want to try a volt mod I'd try making a post about it in the AMB mobos section of the forums - Colin seems to be the person to talk to about volt mods, so if you can get a hold of him maybe he could help.

Answer 2:
I think you may be a little confused - either that or I'm misunderstanding you. The '266' bus of Tbirds is actually a 'dual-pumped' bus similar to DDR, so although the cpu runs on a 133 bus on the board it's effectively 266 in terms of data transfer. You don't need to raise the fsb to 266 - that would have the cpu effectively running on a bus of 532, which would almost certainly fry the chip instantly! The highest I've heard anyone getting the fsb to is generally about 180 in extreme case, though the norm is around 140-160. I think with the Epox boards there is a 1/5 divisor in some bios versions, which keeps the PCI and AGP speeds in spec at 166 fsb, but as far as I know no other boards have such a bios.
