Tearing my hair out here. I am trying to upgrade mine and my son's computers. Bought two Asus A7V880 motherboards together with Athlon XP 2550 (Barton) and Athlon XP 2800 (Barton) processors (all from different vendors) but neither of the processors will run in either of the boards. My old processor, an Athlon 1100 runs fine in both boards. I have the system fully working and booted to Windows with the old processor but if I take that out and drop in either the 2500 or 2800 - nothing, doesn't even post.
Two options spring to mind - either the motherboards need some sort of tweak or the psu (the only constant left) is not up to it.
On the motherboard side, both boards have the latest BIOS and I have even set the BIOS manually to the correct voltages and FSB etc. for the 2500 (at least I think I have). PSU specs are
300W
+5v | +3.3v | +12v | -5v | -12v | +5VSB
25A | 20A | 13A | 0.3A | 0.8A | 2A
180W Max | 156W | 1.5W |9.6W | 10W
Running Speedfan (with my old processor) gives me
VCore1 1.87V
VCore2 0.00V
+3.3v 3.26V
+5v 4.92V
+12v 12.03V
-12V -16.9V
-5V -8.78V
+5V 5.03V
Vbat 3.28V
but I don't really know what all this means.
So do I need a tweak on the motherboards or is it the PSU? If the latter please tell me what PSU I need as I don't want to spend another £50 for nothing.
