Re: Does this look like bad caps?

A nice Northbridge cooler to replace the one that wasn't really glued on very well;

....and that matches the SK6+ coolers.


-------------------------------


And if i had the time to wait, Mouser has the proper 1000uF, 16v, 8mm caps in Nichicon HN series..........................or will have them in 14 weeks.

Re: Does this look like bad caps?

Ahhhhhh, Shit!

I ordered 12.5mm caps for the "L". The new parts havn't arrived yet, i just double-checked the part numbers.

I guess i could use the 16v, 1500uF MBZ caps, but i don't think it'll come to that. The CPU's aren't here, and i don't have coolers for this thing yet.

At least i got the 1000uF, 16v parts right.

Re: Does this look like bad caps?

Reordered the PROPER 1500uF caps. This time at the original 6.3v instead of 10v, which is how i made the mistake in the first place.

P12357-ND is a 12.5mm, 2200uF, 10v cap
P12356-ND is a 10.0mm, 1500uF, 10v cap

Anyone want to buy some 12.5mm caps?

Re: Does this look like bad caps?

Well maybe i'm not 'stuck' with them.

Hey TC, are these 12.5mm caps?

This looks like my next upgrade........ .........provided that everything works.

Re: Does this look like bad caps?

So far, this is what i have;



1000uF, 10v, 8mm - Rubycon MCZ
1000uF, 16v, 10mm - Panasonic FM
1500uF, 6.3v, 10mm - Panasonic FM


I think the cap values are close to original except for the 8mm, 10 volt, 1000uF. Were these 16volt originally?

The 10mm, 16volt caps took a little bending of the leads to get them to fit nicely in the two spots in front of the AGP slot. They now sit 1-2mm higher than usual.

i use 1000@16 fm in front of agp on all the vp6 i rebuild.
just dont force them in as you can ruin the bung.
those are the only ones that MUST be 16v.
one i am posting from has 2200@6.3 fm everywhere else.

Re: Does this look like bad caps?

Oh, no. I used a small pair of needle nose plyers to bend the leads and fit each one to its new position. Only then did i solder them in place.

Thats why they sit a little higher than usual.

Re: Does this look like bad caps?

I'm not sure this board is working properly.

Initially it wouldn't display anything on startup. Then i popped in a PCI card and immediately went into the bios. Both CPU's seem to like 82 degrees.

So far none of the Linux LiveCD's i tried work completely. Either they arent compatible with the VP6 or something is still wrong with the board.

Would it be unusual for the author of a live CD to include the chipset used by the VP6? It's on the old side, sure, but it's still unusual for an older system.

I made sure to load 'Failsafe Defaults' in bios and rebooting before really setting anything. After this the AGP card that wouldn't start before seem to work fine.

I decided to install Win2k becuase it would be the frame of reference that i'm most familiar with. If it doesn't do what i wan't in win2k then there is something wrong with it.

But it appears that i've given away every IDE hard drive of insignificant size. I have a few reeeeeally old drives but 512M is too small for a win2k install.

Maybe a 2 to 4 Gig CF media would suffice since i already have one of these;



I could get more use out of CF media than a comparable sized 'old, used up hard drive'.

Re: Does this look like bad caps?

Hmmmm.......it seems to run BeOS 5 from the tiny disk though.....

Re: Does this look like bad caps?

Since i can make this post on the VP6, can i assume that the past failure to launch this machine was a lack of proper configuration for Linux?

Re: Does this look like bad caps?

run memtest86 and see if it passes.
then beat it up with mprime.
both can be found on ubcd
no live distro i remember has failed to run on a vp6 and i have had quite a few in for recapping.

Re: Does this look like bad caps?

I think i have a copy of that around here somewhere.........yes i do........results to follow......

I've seen systems hang a particular state before but this one is still acting funny.

This is at least encouraging:

Re: Does this look like bad caps?

gastorgrab; just FYI I think I have that exact CF adapter too and if it's the same as mine it does not support DMA mode...

Would that matter if i was booting a Live Linux CD?


I finally switched to using a former paper-weight in it's place. That what i loaded BeOS to.




Keep in mind that this is a test setup and it will determine if 'real' parts will be procurred.


--edit--


It wasn't running very long but the RAM appears to be OK.

Re: Does this look like bad caps?

What am i looking for here in mprime?

Will it make the system lockup if there is a problem with the board?
.

[gastorgrab]

Re: Does this look like bad caps?

MPrime was pretty uneventful so i decided to try the LiveCD again.

I't doesn't hang at the same place now. Before, half of the splash screen appeared and thats as far is it went.

Could the CF drive do this?

Now it goes clear to the Mepis desktop but i'm not sure it's freezing. The hard drive light continues to flicker as if it's still trying to load and the mouse responds every 20 seconds or so. It's like the system was loading very very slowly.

This behavior is likely caused by the only 128Meg of RAM in the system. It's all i could dig up.

Anyway, DSL loads and runs well enough to post from.

I'll have to buy some RAM i guess..................and a hard drive. But it looks like this thing works.

Re: Does this look like bad caps?

A side note:

A short review for anyone considering the cheapo coolers like this one from MassCool.....




It required nearly 3 hours to grind the concave surface to something resembling flat.

I've never seen one this bad, right out of the box before.
