eMac now at 900Mhz!!! (now with pics!!!)

more thermal paste or at least higher grade might work

8-o Not more! If anything you want less. Thermal compound is only intended to fill tiny gaps and other surface inconsistencies, not drown your CPU.

i know what it does thats why i alo said higher grade

Also, the eMac's fan is some screwed up proprietary funky shaped specially designed shit fan. From what I have seen you would be hard pressed to replace it decently.

That's hilarious. OEMs do have a tendency to install the cheapest hardware ever, though. Back in the day, Apple used to install NMB or Nidec fans in their systems, and you'd be hard-pressed to kill one of those.

Anyway, the first thing I do with buzzing/vibrating fans is clean them, then oil them. 90% of the time, oiling them up will return them to like-new operational status, which is especially helpful when faced with a dying proprietary, funky-shaped specially-designed shit fan. The only time this doesn't work, really, is when the fan has been run so long without proper lubrication that it seizes and/or destroys the bearings.

Well, I don't know if it was that low of quality.. It was just entirely proprietary and thus was what I called it.

I would hate to have to source or hack up a replacement...

Pics are in!!!Overclocked eMac from 700->900Mhz

error 404

And WoW is known to put a hurting on overclocked CPU's. I wouldn't recommend running it on an overclocked machine. 700-->900 is a bit severe, anyway. You might get away with running it at 750 or 800 without it becoming unstable.

900MHz was too fast for me as well for my 700MHz emac.

Instead I increased the bus speed to 133MHz which allowed changing the CPU to 867MHz. With PC133 RAM, 133MHz worked.

To change the bus, add a solder bridge or short across R303. R303 is next to the CPU; almost under the heatsink.

To get 867MHz use a CPU multiplier of 6.5X. Here are some multipliers for a 133MHz bus.

______6.5x__6x __5.5x

R1506 short open open

R1509 open open short

R1512 short short short

R1515 open open open

R1518 short short short

At first 867MHz gave me a similar installer error as you but I had also slowed my fan down. I put the fan back closer to its original noisy speed and leopard installed fine and the emac is running fine. With the slow fan speed the temperature coming out the back was around 100F. Normal speed fan was 90F.

I ran this CPU Test for a few hours and it was fine.

Good Luck
