possibly the world's fastest eMac...

[alectrona6400]

yeah, i was real bored and i don't know what this would be for. but i have acquired a 1.42GHz eMac board and overclocked it to 1.92GHz. could not have any success with it going any higher, but it should be fine. 2GHz is really only an 80MHz increase and i'm not sure if it would be worth it. to get it stable, i set the vcore to 1.375V and bridged the remaining clock resistors to run it at the desired clock. i used to have a 1.25GHz education edition 2005 board (820-1798-A) and i was only able to get that to 1.67GHz stable. this computer flies under tiger and somewhat even leopard with visual effects turned down. i might plan to find a 7448 and see how far that would go, but i have NO experience with BGA work and this seems to be pretty viable already. now why did i do this? i was bored and i had nothing else to do.

Great stuff. Got an SSD in there?

not for now, but i plan to look at some options.

If it really is to be the world's fastest, it needs one.

yeah... i've been thinking about it for a while >.>

Do you have tested this also under heavy load like Cinebench CPU tests or MacPorts compiling (or even running an emulator night and day)?. In my experience also the DRAM was crucial for a stable overclock, at first sight everything seems ok but on the long run I had to change the RAM modules with another brand because the first (a Geil brand with red metal heatspreader) was the cause of crashes and freezes: now it runs flawlessy with a more "ordinary" couple of 1 Gb DDR sticks with memory chips exposed and latency 25330. I know it should not matter since the memory bus is not subject to overclock but maybe the size of heatspreaders was itself an obstacle to a better cooling of the memories, this problem caused me severe troubles using high performance 4x512Mb CL2 modules on my G4 MDD since they were too much close each other once fitted in their socket, in the end I reached a perfect stability using 2x 1Gb modules: same memory size visible to system but much more fresh air around the heatspreaders.

I wasn't even certain if IDE SSDs even existed, but a quick Google search told me that yes, they are indeed a thing:

KingSpec 128GB 2.5-inch PATA/IDE SSD Solid State Disk (MLC Flash) SM2236 Controller

Storage Capacity: 32GB/64GB/128GB/256GB NAND Flash: MLC Sequential Read Speed: up to 80MB/s Sequential Write Speed: up to 50MB/s TBW: 375TB 4K Random Read Speed: 3120 IOPS Max 4K Random Write Speed: 472 IOPS Max Work Temperature: 0～+75℃ Storage Temperature: -40～+85℃ Enviro...

It'd be interesting to see that in an eMac with the requisite 3.5"-2.5" IDE adapter...

What I really want to know is if you can run OS 9 on it. Because then it's the perfect PPC Mac!

Don't waste money on an IDE SSD.

They suck.

All of them.

The way to go is a modern mSATA SSD in an mSATA to IDE adapter. Many here have successfully done this.

mSata in my iMacG4 and it is working well. I’m always using normal mSATAs or SATAs with Adapter in my Retro Macs without problems.

i'm gonna run geekbench 2

unfortunately, the radeon 9600 does not support OS 9. it would be doable, but it won't have graphics acceleration.
