6400-->6500 mobo
Posted by: aphetica on 2008-06-05 12:31:28
Can I swap a 6500/300 mobo into a 6400 case without swapping the power supply, or will the extra 100mhz be too much for it?

Also, the 6500 doesn't have onboard ram like the 6400, right? Does the board have traces leading to where ram should be, but no chips? Or is there simply nothing there at all?

Yep, I'm pretty sure the motherboard swap will work with no issues - the 6200 to 6500 boards can be swapped between machines and will still work fine. Not sure about the RAM, perhaps someone else can shed some light on that...

No onboard RAM (except for the ATI video chip's dedicated SGRAM, w00t).

I don't remember if there are pads or not; I haven't played with mine for a while.

The 6200 through 6500 machines CANNOT be swapped. The 6360-6500 can, but the earlier 62xx and 63xx motherboards can't because the power supplies are drastically different than the later machines. The later machines need more power so if you plug a 6200 board into a 6500. (why would you even want to?) you will probably burn it up.

I have a 6500 MB in my 6400 case, works fine.

I put a 6500 board into my mother's 6400, as the sound was dodgy on the 6400 with the G3/400 upgrade. The 6500 *and* G3 together worked just fine, too.

I put a 6500 board into a 5260 once, and mains AC came out the SCSI port! :?:

DO NOT WANT!

Something really crazy must have happened with the chassis ground!

Thanks for clarifying that. My experience in the field is basically putting a 6400 motherboard in a 5200, which worked perfectly. I assumed the 5200 was simply a 6200 in a difference case with a monitor built-in, though I'm guessing the power supply is going to be quite different from a 6200.

I've heard you say that before, but still...how the HELL did that happen? And did the board (and Mac) still work after? :O

Yes! It was booted and running at the time
