Speedbumping a Lombard 400MHz bus to 100MHz ???

I have just been informed of someone bumping a 500MHz IceBook from 66MHz bus to 100MHz by soldering a resister ?! Is it possible to do this on a Lombard 400MHz ? Any other (worthwhile) speed increase possible ? Larry _ Express

Yes, it's possible, but you may not actually want to do it. The thing with bus speeds on the Lombard is, both the processor and the Grackle PCI bridge/memory controller have their own PLLs to generate the 66MHz clock from the 33MHz PCI clock. So, there are 2 sets of multipliers to adjust. I

The 250 and 292MHz Wallstreet Is had 83MHz buses; the later PDQ (Wallstreet II) models didn't. Thing is, the 300MHz/66 bus PDQ is generally faster than the 292MHz/83 bus Wallstreet, despite being based on almost identical hardware, and others have found that changing the bus speed of G3

From: Ben Dyer [EMAIL PROTECTED] snip If not, don't worry, because the bus clock rate increase from 66 to 83MHz makes virtually no difference to system speed anyway. I'm inclined to agree. It's easier selling it and getting a Pismo... Larry
