Abit ST6-R full of Teapos caps

Re: Abit ST6-R full of Teapos caps

Looks like the cap has been reversed, all the other caps have their negative facing the other direction...?

Re: Abit ST6-R full of Teapos caps

I get so paranoid about doing that I check 3 times before soldering

Thankfully, it's an easy fix trodas eh?

Re: Abit ST6-R full of Teapos caps

I check it once before soldering and once after - using a multimeter to confirm that the negative lead of all caps is connected to GND (this might not be always true as there can be a cap on -5V or -12V rail).

Re: Abit ST6-R full of Teapos caps

looking at your pics of the original teapos on the board, that cap is indeed incorrectly installed reversed

Re: Abit ST6-R full of Teapos caps

Okay, guys. You all figured it out My bad. I can't understand how I can did THAT mistake, but I did it.

Well, at least we all see what Pannyes are made off - a thick yellow stuff inside

And of course I fixed it and computer is stable again, heeh. Easy stuff. Next time I won't be so careless and check and re-check more

Poor cap

But OTOH - if I desoldered it first, no-one could notice my mistake and I could claim that I was the unlucky and get one bad piece of Pannyes
And I do believe it could happen for any brand at all. We seen even Rubbyes, Chemi-cons, Nichicons and Pannyes blow out - now just let's wrongly polarize Samxon to see what it is made off inside

Re: Abit ST6-R full of Teapos caps

Todays I replaced (for playing safe) all the rest of small caps - damn Teapos, so, they gotta go

Frankly, there is unbeliable amount of them - 20 pieces of the small ones. 7 are 22uF, and 13 are 10uF ones. Two of the 22uF ones I replaced with 33uF Panny FM 35V ones, as they are on filtering for the fan's, so... For rest five 22uF I used Panny FM 50V ones. The 10uF ones I fitted with Panny FC 25V ones, but only two - in two cases, where I can't solder from back of the PCB a SMD 1206 ceramic 10uF cap because the conductible hole(s) are so near...

It does not give me more OC - however maybe the other that 3:3:1 divider now work's, I don't know. I just tried 126Mhz FSB (1764Mhz, whoooa but it crashed on BSOD in Win, so, back to long time proven stable 120Mhz. This board probably can't give me on 3:3:1 more entierly stable and no other divider does work - or worked, I was too pissed from the Eurocase PSU weird results, that I did not tried the OC really hard, if at least 122Mhz won't work for me...
(for the record, I was encounter ocassional crashes at 122Mhz, so I get back to 120 for stability, also 1.625V it seems is need, but that could be attributed to the reversed cap too, so maybe I should give 1.600 try again...)

That bring the caplist used to this:

Abit ST6R
---------
10x 2200uF 6.3V r10 - P12344-ND
7x 1500uF 6.3V r8 - Samxon GC
7x 120uF 16V r6 - P12922-ND
2x 33uF 35V - P12925-ND
5x 22uF 50V - P12927-ND
2x 10uF 16V PannyFC - P11212-ND
11x 10uF 16V SMD 1206 - 490-3911-1-ND

Re: Abit ST6-R full of Teapos caps

Was it really worth replacing caps of 120uF and below? Most members state that these are not necessary to replace.

Re: Abit ST6-R full of Teapos caps

Well, at least he knows it'll last this way. The small ones do go occasionally, it's just harder to tell.

My neighbor's Abit (couldn't get the model) is still fine.

It's a VH6T. Of course, now it's dead. Biggest recapping incentive yet, cause he thinks there's something worse wrong with it = free Celery 1.1...

Re: Abit ST6-R full of Teapos caps

davmax - just to say, these was originaly 100uF ones, yet I recapped them with 120uF ones.
And the small ones given me troubles on Abit KD7-G, so I won't leave ANY small cap - especially not from brands like Teapos (presented in past on my Abit ST6-R) or Hec ones - you seen what they can do, did you?


Shroomie - congratulations on getting free board with CPU - just worth the repair cost of caps
