PIII 800 mhz @ 1.75v VS. 850 @ 1.80v

Hello guys. I've got a PIII 600 I've been able to get stable at 800 @ 1.75v. To get things solid at 850 I have to bump the core voltage up to 1.80. Is this too high? I don't want to stress the chip too much and I'm not really sure what the "safe" limit is on these. It's an fcpga and it's the previous stepping to the CB0's. Slocket is an Iwill II and the motherboard is a Gigabyte 6VX-4X. This motherboard seems to automagically tack on an extra .05v to the core, so my actual slocket settings have been 1.70 @ 800 and 1.75 @ 850. Thanks for any input on this.

Oh yeah, the cooling on this thing is the retail heatsink and fan with silver grease. I've never seen it hit over 90F, but then my temp sensor is external to the chip and just next to the heatsink. I figure that'd make the reading about 10-15 lower than the actual chip temp, but that's just a guess.

Ack, was poking around Intel's site, and found that my Iwill II is in the "Slot-to-Socket Adapters That DO NOT Meet Minimum Functional and Voltage Requirements of the Pentium® III Processor in the FC-PGA Package" table. Should I be worried about this? I got the Iwill II back in February when it was THE slocket to get. What's the best one to get now?

As long as you are stable with that slotket, don't worry about it. I think 1.80 volts is fine....I'd be reluctant to run at anything over 1.85V.
