Is it safe for me to overclock my FSB to 140?

[snidy]

would it be faster to change the FSB or the CPU multiplier? and how safe is it?

Multiplier is usually the way to overclock, provided you have unlocked your CPU. Raising the FSB will do the trick but depending on the motherboard and other components you may not get to far before problems crop up.

I also have an A7V and cannot get over 133fsb stable. My 1ghz Bird it at 10.5x133 at the moment and solid as a rock.

No, it is not safe, as it voids your warranties. It also stresses your system. However, I've been running at 140fsb for about a year now and don't have any problems with my computer or peripherals. I understand this is the case for most people. Just be aware that you are taking a risk

I dont belive fsb is safe at all, stick with standard fsb's, any others are risking your componants

a7v were not good fsb overclockers.

as far as performance impact, fsb overclocking has a greater impact than multiplier. that's because it speeds up your memory, pci, and agp speeds.

that said, it also is more risky/tricky in that your other components need to be able to handle the higher speed.

i actually do both. first try and find the highest FSB speed and keep the multiplier low so total clock is not an issue. when stability gets shakey, ratchet down a bit and then work on the multiplier.

maybe not the best method, but it's worked for me.

My reccomendation is to use the highest possible FSB that is stable on your system as FSB overclocking will yield better results. For example, a 1200 TBird clocked 9*133 is faster than a 1200 TBird clocked at 12*100.

So go for the FSB first, see how high you can get with a stable system (by the way, the best way to do this is use the Prime95 Self test or Torture test). If you get to a point where the system is unstable, then back down a bit with the FSB and up the multiplier. What you want to find is the combination which yields the highest FSB and highest overall MHz. I know this wasn't the best explanation, but you should be able to figure it out.

I have an A7V133 with 512 Megs of Crucial RAM. I am currently running my system at 8.5*149 (yes I know this is a piss-poor overclock with my 1200 Athlon, but the chip just will not run stable over 1280, and 1270 in the summer). So hitting 150 FSB is very attainable. Some have gotten well over this on the A7V133.
