The 80 mm fan does not do anything to cool a GPU (or more importantly the VRM) in my experience. The fanless GeForce 2 mx runs way too hot even with an 80 mm base fan. I think you’d need to rig something on the GPU itself with the 9250.

I have an L3-cacheless QS/733 that I put an 867 with L3 in, and I recall the benchmarks making me think the cache is working. Now you've got me wondering.

Following! I have a working 20” ADC with a giant scratch in the polarizer.

I found a P4 out for the trash once, hauled it home because I needed an AGP to flash cards. It was a freaking PCI express Prescott!

Do you have a link to GF Ti ROM Maker? I recently repaired a Ti 4200 I'd love to try if it's possible to adjust the clocks.

I had a supercap leak in the iBook. Was a pain to get out with the corroded terminals too.

The only time Marathon 2 uses floating point arithmetic is at startup: it builds a set of trig lookup tables. But it will need a real or soft FPU (SANE? I’d have to look up what the original code does) just long enough to build them.

I don't know if it still works this way in Netatalk 4, but in older versions there is the "ad" command for manipulating files.

Actually, is it possible the BGA solder was starting to give, and putting the heatsink back on shifted / compressed the CPU in place such that it resumed working OK? I hope not, yuck!

Yes, running OS X happily for hours, and crashing in OS 9 sounds familiar. I have no idea why they behave that way, or why disassembling it / redoing paste / reassembling it fixed it. It would also behave better in a Quicksilver than a Sawtooth. I think there is some amount of magic involved...

I agree it's a hardware problem, but I don't think it's tough to narrow down if it runs for hours with the original CPU without issues. The upgrade card is bad :(

I used to get random crashes with the ST G4 in multiple machines. I removed the heatsink and re-applied heatsink paste, and put it back together. Have not had a problem since.

My Sawtooth has an ST G4 1000, boots 9.2.2, and I've never messed with Apple CPU plugins. First I've heard of them.

The Yikes! is only listed as having 400 MB/sec bandwidth, vs the 800 MB/sec in the Sawtooth. (https://www.theregister.com/1999/12/02/apple_drops_yikes_mobo/) So, would a G4 ZIF add anything to a B&W G3 besides SIMD? I have one in mine, of course...

I borrowed a torque wrench from work to tighten the CPU bracket screws back to Apple’s spec. Dunno how necessary that is but it was probably the trickiest part. It’s an easy upgrade.

It will crash in sleep (sometimes?) if it tries to suspend to disk. It reports a machine check exception after reboot. Regular sleep (suspend to RAM) works fine, and only uses a few watts.

I have not watched the frequency while running a game—just assumed it would do as spec’d. Geekbench single core is similar to other Ivy bridges with the higher turbo. Sequoia runs well but there is some issue with the WiFi patches that makes command line utilities take close to a second to...

I have the E5-2667v2 so that does boost to 4 GHz, higher than the E5-1680v2 or the E5-2697v2. Better for gaming and general UI responsiveness. But the 12-core will win at Photoshop or compiling. Either is a cheap, easy upgrade from the 4 or 6 core base models. They are great machines now for the...

In the 6,1 the 12-core only gets you a 16% speed increase at multicore; despite having 50% more cores, the clock speed is lower and it'll hit its thermal limits quickly. It's also 12% or so slower at single core (it can't turbo boost as high), which is what you notice most in day-to-day usage...

Have you used an Apple Silicon computer? They are absurdly fast, quiet, and cool. The laptops wake instantly, run for 14+ hours on battery. One of the biggest improvements to personal computers since I’ve begun using them in the 1990’s. Just because you’re not paying attention, doesn’t mean...
