Ga-8inxp

[Bulldog]

Hey guys, I've got a Gigabyte GA-8INXP board. It failed a while ago slowly starting locking up. Finally one day I reset it and it wouldn't post. If I turn it off and back on enough times it will finally post and load windows then just hard lock. But once I completely remove power from PSU it starts all over. Have to power cycle a bunch of times until it'll post. I just recently learned about the "bad capacitor" ordeal. So I looked over the board and for sure can identify 2 capacitors leaking from the top. I'm not sure what brand they are *boards still mounted in case*.
I'm really putting all my marbles in, that those caps are the reason.
Anyone else have experience with this board?

Thanks Mike.

Re: Ga-8inxp

remove your board from the case. you cannot do much without it out in the open.

then, replace all the caps of offending brand (post the brands you see and we will tell you...)

but first, REMOVE THAT BOARD!!!

Re: Ga-8inxp

What PSU does it have? That's probably as much to blame as the mobo.

Re: Ga-8inxp

Its on an Antec TrueBlue I already did all the troubleshooting. Tried other PSUs to the same effect.

I'm going to pull the board later.

Re: Ga-8inxp

TrueBlue is from 2005 era. Knowing Antec, likely Fuhjyyu caps galore. Using that PSU without inspecting it is asking for problems.

Recap the board. From the pics I can find you may have 18-20 caps to do.

Supply us the quantity of each / brand & series / capacitance & voltage / diameter & height. We can help you make choices from their.

Re: Ga-8inxp

open that psu... i bet you will find lots of bloated caps as well. older antec was pure shit for caps.

Re: Ga-8inxp

Okay, I got the board out and I'm trying to identify one of these. Its Black and White. says HM(M) 105C A0304 then in small print i can't make out what the first letter is but may be Nichicon. Its a 1000uF 6.3v have at least 5 those around CPU area. Another problem bloating one is KZG 3300uF 6.3v.
Also has some smaller GSC around the board 100uF 10v

I added some pics my camera isn't the best but give me an idea which caps I should do.

Re: Ga-8inxp

Badcaps.net has one stop shopping for your caps. The shopping cart is now online.

https://www.badcaps.net/pages.php?vid=22

Replace ALL the KZG's.

Replace ALL the HM's near the CPU's, Northbridge, RAM slots, and on both sides of the video slot.

Include the 4 Rubycon's (Blue & Gold). You might as well replace them since you're there already.

Basically, any cap with a vent marking on top (X,Y,K, etc.) in that area should be replaced.

KZG's -

HM's you identified (so far) -

Would you take another pic for here? A nice straight, down-shot that covers everything from the front of the board to the peripheral plugs and over at least to the far side of the video slot. I'd like to see the "big picture" of what you have to deal with.

I disagree. If the cap is a reliable brand like Rubycon, it won't usually fail. I leave good caps in place when repairing motherboards and it works just fine. You could probably leave the Rubycon caps (the K-vented ones) in place, but replace the Chemi-Con KZG and Nichicon HM. Having said that, though, there's no harm in replacing the rubys if you really feel like it.

Re: Ga-8inxp

>>it won't usually fail.<<

Usually being the key word here. So you are leaving the door open to come back and tear this all down again in the future?

Your disagreement makes no sense to have to rework this project for $5 worth of caps.

That along with the fact it's a roaster in there with 2 CPU's and the Northbridge. Yes, the air moves well... hot air right across all those caps.

I've pulled Ruby's and Sanyo's out that read fine in ESR and capacity, and are 8x and more over leakage specs. Then have the one right next to it be perfect in all respects.

Re: Ga-8inxp

I'll replace them lol it was a pain in the ass taking this board out as the system is water cooled. Let me get a picture later on of the overview.

Re: Ga-8inxp

OK, sorry Toasty. I hardly ever see good caps fail (other than in Dell roasting ovens), but obviously, you have.

Re: Ga-8inxp

>>as the system is water cooled<<

Good Grief! Even more reason.

@ c_hegge - No apology needed. I just hate to see anyone have to tear something apart again and again. I've been beating on that drum since I became active here. Also, 30+ years doing repairs and such teaches many valuable lessons.

Plus I'm anal-retentive and a perfectionist and liable to go "Sybil" at any moment...

Re: Ga-8inxp

Ok here are the pictures of the overview.
Also, how do I know if they are 8mm or 10mm?

Re: Ga-8inxp

while i cant remember the last time i saw a mbz blown i would replace all the vrm in and output caps along with any kzg or hm/hn.
do it right and once.

[etnietering]

Re: Ga-8inxp

To figure out if they're 8mm or 10mm, take a ruler (with mm markings) and measure the diameter of the cap (the fattest part). If it's 8mm (or close), then it's an 8mm cap, if it's 10mm (or close), then it's a 10mm cap.

Re: Ga-8inxp

I'm not very familiar with each circuit so i dunno where VRM in/out is.
I have got a list started of which I'm planning on doing correct me if you think otherwise please.

https://www.badcaps.net/store/produc...products_id=48 Quantity x 14
I counted all them on the entire board is this necessary to do?

https://www.badcaps.net/store/produc...products_id=30 Quantity x 3
TO replace the 3 tall KZG junk only 3 on board and all are bulging.

https://www.badcaps.net/store/produc...products_id=38 Quantity x 1
Only one KZG 1500uF 16v

As for the 4 Rubycons I'm not sure which to replace them with as they are marked 6.3v 1500uF MBZ I did not see MBZ in the Ruby list for this voltage/rating only MCZ.
Toasty you were referring to the 3 Rubys between the mem slots and cpu socket, and the single one on the other side next to the KZG? I think they are like 8mm round by 20mm tall?

[Bulldog]

Re: Ga-8inxp

Yellow is the x14 Nichicon 1000uF 6.3vs
Green is the x4 Rubycon 6.3v 1500uF MBZ
Red is the x3 KZG 3300uF 6.3v
White is the KZG 16v 1500uF

Re: Ga-8inxp

..............?

[c_hegge]

Re: Ga-8inxp

The caps you have listed shoud be fine. You can replace ruby MBZ with MCZ.
