Differences between the B&W and Yikes! Heatsink

[filipetolhuizen]

Are there any differences between those 2? I just tried the voltage tweak to make my brand new G4 ZIF 400 run at 500mhz but it failed. The machine freezes a few seconds after boot, or during it, sometimes with bomb error messages. I followed exactly this: http://xlr8yourmac.com/G4ZONE/G4YIKESOC/500MHz_yikes.html

but it failed. However I succeeded with a G4 zif 350 to run at 450mhz with the same voltage tweak.

Could it be because the B&W has a different heatsink from the "Yikes!"? Mine is a B&W using the G4 zif module from a Yikes. Any help is appreciated.

Regards,

Filipe

PS.: I already have extra cooling added (2 additional fans attached to the heatsink and thermal grease)

If it worked with the 350 but not with the 400, I'd say the problem is probably with the 400 chip rather than the ZIF or the heatsink. I suppose it could be a problem, but not likely since you already have additional heatsink fans.

[EDIT] Really, you may as well get a Sawtooth on eBay--they're dirt cheap these days. I have a 500MHz Sawtooth that I absolutely love.

Not only they still extremely expensive in here, but also I need Mac OS 8.6 and would be harder for me to flash agp cards.

That is true. I always forget the Yikes! doesn't have AGP... but you're chipping a B&W, right?

That's right!

Sometimes I see some used Sawtooth with low prices, but it depends on the vendor and normally is out of town, so there's the high shipping cost and no OS 8.6 [] ]'> . Some people think because it's a mac that they can get 200% profit on it even if it's an obsolete model. I've seen some people selling Classics for about US$ 700 in here (converted from our $ unit).

I see 500Mhz iBook G3's going for $250 or more. Same with some of the upgraded iBook Clamshells.

Are the CPU cards expensive too in your area?

Not really, but they are way rare to find. This G4 400mhz zif I got on e-bay. I could not find one in the whole country. Even complete Yikes! are not found in here.
