I upgraded my old athlon 1.0g t-bird machine yesterday. A local place had a cpu/mobo combo deal for a 2.4g P4 & ECS P4VXASD2+ for $159. ECS has a poor track record with me, but since the place is right here I figured I'll take it back if it doesn't work. I am using my existing case, 350W psu, ATI 8500le video, WD 40gb 7200rpm drive, and cd-rom and floppy. I planned on a fresh win98 install so I reformatted the C partition and have the cab files on D.
The machine posted intermittently, and when it did it kept hanging early in the win98 setup. I switched to a larger psu and that did not help. Swapped out memory and video card also, to no avail. Then the next day the machine would not post at all so I went back to the store and exchanged the p4vxasd2 mobo for another. Got home and that one would not post either. Then I switched the fsb jumpers from 133 to 100 and now it runs fine, as a 1.8g. The cpu temp is 34. I did not think to exchange the cpu at the store since I just assumed the problem was the mobo but now I don't know. This is exactly like the problem I had a couple years ago with the via kt266 chipset, which would only run at 100mhz as well.
Now that win98 is installed and running fine I just tried switching the jumpers back to the 133 fsb and now it will post as far as the system information screen where it tells you that its running at 2.4g plus a lot of other detail, but it halts there. Not a hard freeze though as ctl-atl-del will cause a reboot. The halting is happening right before I get the chance to hit F8 to go into safe mode. This mobo is a ddr/sdram combo and I'm running pc2100 ddr. The manual implies the fsb jumpers are optional and that the board will detect the proper speed without them, but when I booted with the fsb jumpers all open it would not post at all. Thanks for any advice.
