BSOD and Gigabyte Capacitors

Re: BSOD and Gigabyte Capacitors

Thank you so much, mariushm.

I ended up finding the Nichicon HZ on digikey. 3300uF, 6.3v.

Thanks again all!

Re: BSOD and Gigabyte Capacitors

Rubycon MBZ would be kind of hard to find.

Panasonic FC might be a bit too low spec to replace those KZG.
The FM series from Panasonic is better but the capacitors are of larger diameter.
The FR series is meant to be a replacement for FM and it's thinner but taller than FM, which works great in your case. For anything under 1200-1500uF, the FR specs are worse than FM but for anything over they're much better. So again, it works great in your case.

Nichicon HM/HN are ok but you might be lucky to find HZ which is even better.

kzg: 3300uF 10x25 0.012 ohm 2800mA

hm: 3300uF 10x25 0.012 ohm 2800mA
hn: 3300uF 10x25 0.009 ohm 3190mA
hz: 3300uF 10x25 0.0065 ohm 4690mA

rubycon zlg: 3300uF @10v 12.5x25 0.013 2900mA https://cdn.badcaps-static.com/pdfs/...3bb75aa682.pdf

fc: 3300uF 12.5x20 0.038 ohm 1655mA (too low)
fm: 3300uF 12.5x20 0.018 ohm 2600mA (getting closer)

fr: 3300 @ 10v 12.5x20 0.018ohm 2600mA still not quite there
fr: 3300 @ 16v 12.5x30 0.013ohm 3630mA just right

The impedance must be lower or equal than what you initially had, the mA value should be equal or higher.

So as you can see from the values, HM, HN, HZ are direct replacement... diameter fits, impedance and ripple are almost if not identical.

If you can fit 12.5mm diameter caps in there, Rubycon ZLG also works, even though it's rated for 10v. Voltage doesn't matter as long as it's higher or equal than 6.3v

Panasonic FC as you can see is not really good enough, FM is close enough to say you can safely use it if you can fit it there.
But if you can fit 12.5mm diameter caps and the cpu fan doesn't block 30mm tall capacitors, you can safely go with FR 3300@16v which has better specs than KZG 3300uF 6.3v and furthermore, it's rated for 10.000 hours @ 105c - the Nichicon caps are only rated for about 4-6k hours.

You can get the Nichicon and Panasonic capacitors from Digikey.com or maybe from this site's store. Rubycon you can find on newark.com (besides the nichicon and panasonic)

Re: BSOD and Gigabyte Capacitors

You can use Rubycon MBZ/MCZ, Panasonic FC, or Nichicon HM/HN.

Re: BSOD and Gigabyte Capacitors

Thank you for the replies Hemingray and Rulycat.

I was able to read the numbers off the capacitors and was hoping to get recommendations on replacements:

• 3300 uF
• KZG
• 6.3V
• (M)105C
• 4(T)
• DD

Some of them actually had slightly different info:

• Some had 5(T) instead of 4(T)
• Some had 2D, DE, or 20 instead of DD

What is 4(T) vs. 5(T)? and the different two letter codes?

Any suggestions?

Thanks in advance!

Re: BSOD and Gigabyte Capacitors

Some sources suggest they're Sanyo:

Others suggest perhaps they switched to KZG or similar:

Re: BSOD and Gigabyte Capacitors

Yep, bulging caps = bad caps.

Pics would be good here. If some are bulging, all the others like it are likely also bad, best to replace them all at once. Some of the others can suggest a good capacitor type to replace em all with.

Hello,

I built a PC around 2005 for music recording and have used it extensively since then. It has never been connected to the internet and I rarely install new software on it. I configured it for music back on 2005 and left it be! (if it aint broke..)

So this past Saturday, it started BSOD (Windows XP, SP3) at random times. It would boot up fine and then suddenly blue screen. So I assumed a hardware failure given the information above. I went through the standard troubleshooting steps (replaced/moved around RAM, swapped video cards, disconnected all IDE except for main sata HDD, removed soundcard) all to no avail.

Finally, I inspected my mobo and found 7 bulging, leaky caps. Motherboard is a Gigabyte GA-K8NSC-939. Does this sound like it could be the problem? Worth trying to replace the caps?

Thanks!
