p4 mounting hole same as a64 mounting hole?

jimmyang · 10-28-2003, 03:28 PM

Does anyone know the dimensions for the A64 boards 4 hole system? (i know there's some boards with only 2 mounting holes but i heard some others had both 2 and 4)

Is it the same as a P4 mounting hole dimension?

thinking of builiding a block but wants it be used on both a64 and p4 (dual rig)

Not the same.

They are approx ~9cm apart and only one set of two. Havent seen more than that infact.

Edit:The holes are 3.5" (8.89cm) apart

apparently those a64 boards has provisions for 4 holes... it has the 4 blank spots, with apparently no circuitry going through it...

can you say one A64 Motherboard + one 1/2 HP drill-press loaded with one 3/16" bit == warranty smack dab out the window...

WARRANTY?? what's that??? it's a waste of precious time....

my error jd
the 4 non-holes are 'keep clear' areas where the plastic feet of the top retention frame bear against the mobo
- I would suspect there are traces under the top layer

Good point. That is one thing to remember, these mobos may have multiple layer PCB's. Just because you can't see it doesn't mean it isn't there.

Every modern motherboard I've seen (in the last 6 years) has a minimum of 4 layers... some have 8+.

I was refering to muliple layers of traces, not just PCB material (in case there was any confusion).

That too, is what I was referring ... multiple trace layer boards have been around for almost 20 years now...

easy way to figure it out, is to hold the board up to a light.... if the locations of the holes are nice and see-through..... no little lines, then your a lucky-B. if not. well ... you tried

. if it's not see-through at all, it means Vcc and Gnd covers it, and the chances of tracing crossing through is virtually guaranteed.
