Does anyone know if there is a better cpu out there for my v3 io. I don't want to hack the cpu section much, and I'd like to keep power requirements low [I don't want any regulators to burn out]. Are pentium 233 mmx or something like ok? Is that best or AMD...any others? But I think AMD's are hogs when it comes to power. What makes things more difficult for v3 w/ 200MHz winchip owners than say v4/v5? I remember all this stuff was mentioned, but I can't find much about it now by searching. Most is about cpu regulator hacking w/ amd 450's and such. I'm looking for a cleaner option, w/o replacing lots of parts, and it would be nice to hear from people who have already settled w/ their upgrades. I really appreciate the help from anyone. Thanks.

Has anyone had any luck with powerleaps? I know it would require a separate p/s, but would it solve the motherboard heat problems? If I was a better solderer (my good hand is a little mangled), I probably wouldn't even consider it. But if the k6-2+ works with the pl-prommx (see http://208.55.28.22/ubb/Forum1/HTML/000604.html
)
it would be a ~$90 option for those who aren't very good at soldering. I plan on trying it with the pl-k6III/98. I'm also gonna try it with the pl-prommx, because I'm ordering some to upgrade a few computers at Church.

Willing to cut a hole in the back cover and rf shield directly over the cpu area? To do a neat job requires a dremel tool, Patience and some artistic skills.
If so, maybe you can locate a used Intel p-200 "drop in Cpu upgrade" at a local used computer parts shop.
I myself have not done it but someone else posted many moons ago they did and they noted some improvement in overall performance...
Also if you have a Fred Meyers in your area check out there home electronics area. They had the winchip2 233 upgrade kit on clearance for $49.00 plus %50 off...It's socket adapter jumpers are preset and has a fan attached to the CPU. The fan did not require external power either. That was a couple months ago but you may get lucky? PS, That still requires a hole being cut for fan clearance.

Early I-Openers that came with a Winchip can only be upgraded to a Winchip2. If you're willing to do board mods you can use a variety of chips. If your I-Opener came with a Rise chip, you can drop in a P166 or P200....both run ok and benchmark slightly faster than a Rise chip. A Rise chip won't work in a Winchip machine without board mods. My V4 with a P200 runs very well.....no board mods were necessary. My V2 with a Winchip2 is slower, but still makes a good computer....I use it mostly for surfing.
I never tried a P233.....probably wouldn't run much faster than a P200 without board mods. You can cut very neat holes in the I-Opener case and shield without a Dremel. A Radio Shack tool called a "Nipper" does a perfect cut. My P200 came with a permanently attached heatsink and fan....I cut the hole using this nipper....no sweat at all.

Best drop in for the V1 is a winchip 2. At best rare, at worst unavailable. Best drop in for the V4 and up with dip switched vcore is the AMD K6-iii+. The k6-3+ has 256k of l2 cahce on chip that runs at full speed. Even running it at the stock 200 MHz, the addition of the L2 cache makes it outperform any other chip at the same speed and then some. Unfortunately, AMD has stopped making these. Some show up on ebay, but the bid price is $85 and up.

I have a v5 and a p200 dropin upgrade (has a built in fan, once used to upgrade my P5-133, called "overdrive" on the box). Would it be worthwhile to upgrade and would I have to cut a hole in the case?

The P200 I installed in my V4 made a noticeable improvment....and it required no modifications to the board. You will have to cut a hole in the case...the fan sticks out about 3/8". I power this fan with an external 12v power supply.

Yeah...it's a P200MMX. Unfortunately the fan was permanently attached...thermal epoxy. That's why I cut the hole in the case and use an external 12v power supply for it. I had a P233MMX a few years ago that had a removable fan...that's about all I know about these chips. You could probably overclock a P166MMX to 200mhz (2x100)....these are around pretty cheap.

V3's have a single CPU supply voltage and V4/V5 have duel voltage supplies. In order to support a Rise266 you need to move the 0 ohm jumpers R60 and R61 upper right side of CPU socket
Solder these 0 ohm resistors at R184 and R185 at lower right of CPU socket. You then need to put the proper size resistor in R343 for the right rise266 core voltage. I don't know what that value is. 10K gives you 2V.
Thing is, why bother? Go for 2V and putin a K6-II+. I've seen them for 30 bucks and they are over twice as fast at the same cpu speed as a Rise266.
