TBIRD 1GHz O/C

[KK]

I just got done doing some adjustments on my system. I have a 1Ghz TB, I closed those L1 bridges, and bumped the multiplier up to 12.5 Now when I boot the system it says 1250. This is with a 100Mhz bus speed. How much can one bump this bus speed up to? The asus probe has went up about 2C, to about 50C. Is this alright? This is my first O/C, is there anything else I need to know?

Thanks,
KK

KK, tha A7V could get you 105- 115mhz bus. Expect around 107-110 to be actual max though. If your ram is pc-100, it may limit you to lower than that. The temp is a little tricky. Asus probe is inaccurate (as much as 6-12c low), but establishes a good baseline for you. (50c seems about average though) Try to stay around the temp that it was when running at 1.0ghz. By this I mean not absurdly higher. Use a good heatsink/fan- a thermaltake orb of any kind will not do here. Also use some good thermal compound, preferably Arctic Silver. This CPU is going to create copious amounts of heat @ 1300mhz!!

Edit- I'm glad there's not one more K in your name!!

Will upping the cpu bus be better than upping the multiplier? Which will give more of a boost?

Ideally, you want to do both. the bus wont give you as much speed, but it is a higher quality oc; the ram, vid card, and pci bus are all running faster when you fsb oc.

Consider this. 100* 12.5= 1250.
107* 12.5= 1337, and the ram is running faster.
At the same CPU speed, always opt for the option that gives you the fastest bus speed you can run at.(In effect, 1230 @ 107*11.5 is faster than 1250 @ 12.5*100.) I'm using 107mhz bus as an example, but you may get higher or lower bus oc's.
