Re: GA-K8NSNXP-939 bad caps

Well I got the system back up and running after replacing the CPU and RAM Caps

Seems to be stable however I am noticing some odd lag within windows. It also takes longer for the board to post then it did before. So I'm not so sure whats going on. Maybe its possible the CPU sustained some damage? Right now I'm running memtest86 without any ram errors at 20 minutes.

Re: GA-K8NSNXP-939 bad caps

Ok cool I'm glad i at least bought a few extras. That will allow me to replace most of them for now until i order some more.

*Side note* I actually suspect these bad caps were the cause for a stability issue with this board when it came to ram when I originally set it up I never could get the thing to run in dual DDR mode reliably plus I had to manually set the RAM timings in the bios in order to keep the thing from BSODing within windows. This is with good quality higher end RAM too such as Kingston or Crucial(not particular sure what...

Re: GA-K8NSNXP-939 bad caps

I did find out the smaller 1000uF caps are manufactured in 2004(same range as the CPU ones) so they should be replaced. Problem is I'm not sure which ones go to the RAM regulator circuit or to other parts of the boards. I didn't get enough of these to do the entire board esp pci slots, etc.

The Rubbycon replacements are 1000uF 10v as well which worries me thinking they might throw something off.

Re: GA-K8NSNXP-939 bad caps

Just finished replacing the cpu caps on this mobo from the parts I ordered off this site. So far so good it now posts again

Now I just have to decide rather or not to replace the smaller RAM regulator ones as well. So far they look to be in good shape. However they are the same brand/model as the bad ones all Nichicon HM(M)'s with the only diff being 1000uF vs 3300uF.

Actually there is 1000uF 6.3v ones all over the board so its hard to tell which are the RAM regulator ones or others like AGP, etc.

Re: GA-K8NSNXP-939 bad caps

Yeah I went with the Rubycons here plus it helps support the site

Now hopefully my soldering skills are up to par.

I may practice on removing caps from an old ECS socket A mobo i got floating around here someplace first. Its caps went a few years back and i swapped it for an ASUS board at the time instead of a repair.

Re: GA-K8NSNXP-939 bad caps

Ok cool it sounds like the Rubycons may the way to go

I was looking at the [URL="http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P5511-ND"]Panasonic NHG 3300uF 6.3v 10mm[/URL] for the CPU ones on Digikey since I have a bunch of other stuff to order for other projects. They are slightly shorter then the Rubycons at 20mm vs 25mm. It seems the ratted ripple current is lower at on the NHG at 840mA vs 3230 on the Rubycon MBZ.

As for the RAM slots it looks like the 1000uF 6.3v 8mm MBZ has been discontinued...

Re: GA-K8NSNXP-939 bad caps

Hello all looks like you can add me to the list of someone with a bad GA-K8NSNXP-939. Just discovered the system with that board today would no longer boot and when I opened it up I found the cpu caps leaking. I'm not sure on the RAM regulator but I would assume those will be going as well. They seem to be smaller sized though.

Only problem is I'm not exactly sure on what replacements to order and amounts needed.

Oh yeah pardon the dust :P...
