GXm -> GX1 upgrade?
Will the GX1 serve as a drop-in replacement for the GXm?

I was looking at National Semi's Geode pages, and they note that they are going to phase out the GXm series in favor of the GX1. I emailed NS for more info, and they claimed that the GX1 is essentially a GXm created with a smaller process (0.18), and that it should serve anywhere a GXm would, though at a lower voltage. I checked the block diagram and pin-out, and they look identical. The draw is that you can get 333Mhz parts, and they run cooler at their max speed than the 266Mhz GXm does.

Based on the NS email, I bought a sample of the 333Mhz GX1 processor from pioneer ($162!), but the system doesn't boot. I've checked the voltage and multiplier - but no action so far.

Has anyone played with the GX1 at all, or know if they will work in a system originally designed for a GXm?

The 2.2v that the motherboard goes to is really too high for that chip. Furthermore, I do distinctly remember me being told by Allwell's tech people that this motherboard was limited in what it could/couldn't do (we couldn't get a 300MHz CPU to run on it, even though we wanted one...)- we had to wait for the less limited 3036 design to be able to use GX1's. You might get it to run on that board if you underclocked the chip- only advantage there is that it's going to run much cooler than the stock part from the WS.

so are there any processor upgrades that will work on the websurfer? my fan is dying on the cpu, so i figure i would investigate the various options while looking for a replacement fan

Noone that I know of has ever gotten another processor to work in the WSP.
And I have been here for a long time.

As for your fan, I run both my WSPs at the default voltage and 180Mhz.
I replaced the small heatsink and fan with the biggest heatsink I could find.
This passive cooling has worked fine for over a year with no problems. My router
WSP has run SETI 24/7 for that entire time.

I only use the DOC and do not have harddrvies in these units.

what did you use to get the heatsink off the chip? i am happy to pull it off, but i dont want to damage it.

The chip is like an original pentium package, so it is much tougher than the newer exposed core CPUs.

I used a small screwed driver to "carefully" apply pressure between the cpu and the heatsink.
After applying a fair amount of pressure the heatsinks popped off. I did this to 2 cpus and
didn't damage either one.

And you might also want to do it when the chip is 'warm' (but not ON). This makes the goo that holds the heat sink to the chip...well more gooey! Easier to separate then...

well, i managed to get it off with a screwdriver as suggested. these take standard socket 7 heatsinks, right?

A regular socket 7 heatsink will fit perfectly. That is what I'm using. It get's pretty hot to the touch, but like I said, I haven't had any problems. Remember to clean off the goo that held the original heatsink down and apply some heatsink compound to the new one.

The only CPU upgrade options for a WSPro would be for either a 233 or 266 GXm (which should still be available from NatSemi...). The CPU core needs to be jumpered for 2.9v, the multiplier should be 7(233) or 8(266) and the FSB should be set to 33MHz. The chips themselves generate a lot less heat than many modern Socket 7 CPUs so almost any Socket 7 FHS should do the trick- also worth noting is that if you're not using full-length PCI cards, you may be able to get away with fanless operation with a Super Socket 7 FHS without the fan. The reason why I know this is that later models of the Coollogic 7200 (An Allwell 1030N- same thing as a WSPro but with all of the things like IDE headers on the board) used a passive heatsink in the design that was similar in cooling capacity to a K6-II/III heatsink without the fan.
