is this 1.2 OC 1.35 right?

[guppie]

I have FSB set to 150MHz with Multiplier set to 9.0 and VCore voltage set to 1.70

My system seems to be stable and I'm going to run Sandra and 3dMark2001 and Q3 for stability.

I just wanted to see if you guys think this is the correct way to go about OC 1.2 T-bird. I don't think I'll go beyond 1.35, but was I correct in trying to increase the FSB first then get stable and then try to lower VCore to lower temps? How much lower can I go for VCore? Although I have the BIOS VCore set to 1.70, Sandra and VIA Hardware Monitor say VCore is actually 1.75 - thats OK?

Well the faster the FSB the faster your over all system speed will be. It gives more memory bandwidth as well as runs the AGP Bus higher also. The only problem with this is the PCI bus speed. Default is 33mhz. If you start getting up around 38 or higher some PCI cards can be very finicky and tempermental and can cause stability problems. Also Your IDE channels run on the PCI bus. So with that out of spec you risk the chance of data curroption as well. But there are always risks with overclocking. Give it a try for a while and see if it's stable. If it is good for you!

You may want to try 10 x 140fsb. May be more stable and it'll give you 1.4 gigs. You may need to increase the Vcore for this though. I do on mine. I gotta run it at 1.8 to get stability after about 1.35 gigs on my chip. When increasing the Vcore just go one step at a time till it's stable. Only use what you need. The rest is just creating more heat.

Also I noticed your Micron ram is CAS3. Are you running it at CAS3? If you are try dropping it down to CAS2 You will get better performance out of it. I'd be willing to bet it'll do it to. Maybe not at 150fsb but to atleast 133mhz fsb. I had a stick of Corsair PC133 Cas 3. I ran it as high as 140mhz FSB @ Cas 2 with no problems at all. It ran the same speed as my Micron PC133 cas 2 did in benchmarking.

if you want to overclock it further, then up the vcore to 1.85 and see how much further you can get it to go.

You could also try raising the multiplier,, I was able to get 1400 mhz stable out of my 1200 without upping the vcore,, my temps are around 47c idle to 51 full load,, this is with asus probe too. I am tempted to go further but do not want to push the envelope,, maybe you could leave your bus setting and go for the multiplier now.
