Supermicro Super 370DL3

[JEWilson]

I rec's this mobo with a known fault

Sure enough, I replaced a number of bad caps with Panasonic FMs
The failing caps detail the following;

NRSY 10V 1000uF 13mm H 10mm dia
Are these bad caps?

I have replaced 5 of these out of a total of 17 and the board works ok.

It may be prescient to replace all of them as opposed to just the
5 replaced so far

For information, the BOM for electrolytics finds;
17 of Green 1000 uF 10 V NRSY 105 deg C - H 13 mm x Dia 10 mm
2 of Green 1500 uF 10 V Sanyo 105 deg C - H 25.4 mm x Dia 10 mm
6 of Blue 470 uF 10 V Elna 85 deg C - H 11 mm x Dia 7 mm
7 of Sanyo 220 uF Unknown V Sanyo 105 deg C - H 10 mm x Dia 5 mm

Any help, insight advice greatly appreaciated

Re: Supermicro Super 370DL3

well not familiar with that mb but from the small pics I found on it its a dual CPU

I suppose how far you want to go depends on if its for you, for someone else or possibly being used in a mission critical type application.

Supermicro from what I understand made good MB's but went into the server only type MB market (around the time of the PII)

I would expect if the above is the case they would use good caps
but I dont know where the NRSY caps fall in the good bad cap scale

Ideally replace "all" VRM capacitors (this is considered a must do)
and any considered to be junk caps 470uF and up.

The most critical area really is the VRM circuit
(usually caps near the cpu with the mosfets and coils around them)
like the following pic
KZE in this photo are input Sanyo's are output
(KZE 2 near the yellow connector at the back bit hard to see the lt blue)
(orginal thread here)



I'll bet thats were you found your popped 5 too.

So minimally these

If you were going to put it in a situation were its running say 24/7 , if it was me I'd do the lot. (but thats me)

Apart from that, the Sanyo's and Elna's would probably be ok but maybe those 2 1500 uf Sanyo's are the vrm input caps (I dont know)
if they are you would at lest need to check them with an ESR meter although id probably replace them

Sanyo's like these ?
thanks Yanz, photo from good cap photo thread



If they are WG series they seem to last quite well but by now probably have clocked up a few hours.

Others here I know would know this MB and will probably have better Advice on this but this is just my thoughts on it
