Another dumb question.  I know the max ram the mdd is 2gig (512 in 4 slots), but will it take 1 gig stick in the memory slot and see it as 1 and not 512?

Here is the link to my thread on overclocking the board.  It has the link to that site I found in the second post.

Linky!

Cool.

I used a tweezers to pull it off.  It basically crushed when I squeezed it and I just made sure it was not bridging the connections anymore.  You will probably want a magnifying glass so you can see what you are doing.  My tweezer has a magnifying glass built into it.  If your processors are already 1.25ghz ones, you don't need to do anything to them at all except replace the thermal compound under the heatsink when you put everything back together.  You will need the faster ram with the faster bus.  Haven't tried the 1gb sticks yet myself, so no help here.

I can recommend tweezers too. Get some strong ones with a grip to the end and you can slice right through those resistors. Thats what I do on all mine. The ones that don't pull off all in one, I just eat away at em with the tweezers till they do.

As long as you've read the work folks have done and understand what you are doing, should be ok. Considering all the mods i've done on my hardware since I first switched a jumper on my Beige G3 and clocked my CPU, i'd give something like this only a 1/10 in terms of difficulty. If you do attempt it I think you'll probably find out the same then you'll start eyeballing the resistor settings more for that CPU card and wonder how far you can push it.

Really this stuff is fun. Only times i've not really liked tinkering was when I had to use a soldering iron to resolder some of the smallest resistors you'd ever seen onto a Geforce 3 that I got from ebay. The numbnut shipped the board in bubblewrap envelope with no antistatic bag. Card arrived with a bent frame around the monitor connectors and a couple lose resistors. Didn't need the frame anyways since it was for a Cube and for $75 i'd take my chances trying to resolder back on the missing parts.

I think the system itself consumes around 30 megs on startup assuming virtual memory is disabled.  btw, you're running some flavor of OS X as primary, right?

Because of what you got. OS 9 gobbles up a certain percentage of your RAM, whether it needs all that space or not. So the more you have installed, the more OS 9 will (appear to) use.

Not 500 MBs though.

Unles syou go iover itss addressing limit.

From my understanding the mdd is suppose to be able to take 4 sticks of 512 pc2100 ddr for total of 2 gigs. From what I read, the dual 867 can take the pc2700, but doesn't play well with the 2100, so don't mix.   It sure seems like ever time I put the 4th stick in, OS  9 system usage goes way up.  I have not check what the memory usage is for 10.

OS 9 only "sees" a maximum of 1.5 GB. When you install the extra stick, it gets "used" by the OS - it's really just being ignored, but the computer can see it and knows it's there, so it makes something up.

Ever upgrade an SE/30 past 8 MBs of RAM? Same thing untill you installed Mode32. System 7.1, 32 MBs of RAM, and a 25 MB System Heap when you started with extensions off.

Those were the days. :-)

Just install a IIci or IIfx ROM SIMM.

Don't IIsi ROM SIMMs work too? I know the ethernet cards are compatible.
