Tips after unsuccessful recap?

[tnynyn]

Hey guys,

Just recapped my Abit SA6R (jackson for rubycon) but seems it still wont post. Before the recap, I get a blank screen but everything still turns on. Same results afterwards. The LED and fans power on but it wont post with just cpu, memory, vid. I resetted the CMOS, battery, re-seatted the cpu, but still nothing. Any ideas (if i might of done a bad recap job)?? Any way to test the caps I replaced?

Re: Tips after unsuccessful recap?

what was the status of the board before recapping?

vrm damage that happened before the recap.
is the cpu ok in another board?
with the cpu in the board measure the voltage across the caps near the cpu and post the readings.

status of the board was same, powers on, no post. suspected of bad caps (leakage and bulkiness). cpu is in working condition (tested in another system) how do i measure the voltage on teh cap?

turn it over while connected to psu.
power on and test with v.o.m on low dc v range.

ok here are the readings:

2x 1.668 (closet to cpu)
1x 1.5
1x 1.8
rest are 3.3 and 5.0

also, the heatsink doesnt seem to be hot after powered on. Im using the stock socket 370 p3 heatsink (very small aluminum type w/ 40mm fan)

heres the specs:
Abit sa6r recapped w/ rubycon (18)
p3 800 (pulled from a different working system)
128 pc133 memory
antec 350w

ok forget about teh post above, but i think i recapped it wrong. the caps before were 1500uf 6.3v but i used 1500uf 10v on all caps. is there certain caps that i am supposed to keep it at the same voltage?

i dont see a problem there

Re: Tips after unsuccessful recap?

using slightly higher voltage caps wont hurt a thing.
voltage readings suggest the vcore is ok.
without the board on my bench its hard to troubleshoot further.
i would verify any parts you are using by testing in a known working system.
clear the cmos esp since fsb/multiplier ect are set there.pop out the battery and let it die a few hours.

WOOOOOOHOOOOOOOOOO!!!!!!!!!
Got it to work!!!
Did what kc8adu said, left the battery out, put it on clear cmos for TWO days before I got around to testing it again. This time, did one thing different, left the cpu fan unplugged from the mobo. Fired it with just cpu and heatsink and heard the sweetest music ever: beeps indicating no memory.


THANK YOU GUYS FOR THE ADVICES!!! If I never stumbled on this forum, would've thrown out 3-4 boards.
