too bad you cannot use those on anything but vcore and vdimm.
did you get any of the 820@2.5 from that seller?
they would be best for vcore.
i have used some 560@4 for vdimm.
some simple ohmeter testing and marking is in order.

Yea..true. The package was all of the same. I was hoping for an assortment, but since the deal was pretty good, I just went ahead and took the whole bloody lot.

Re: Epox 8KRA2+ blown GSC

That would be sweet mate. I'll definitely take you up on the offer. I did end up with the 10k lot. The seller also had huge 4k-10k lots of Rubycon MBZ. He said it was unopened, but my wallet could only go so far.

Here is a slideshow of pics of the MB. As a first test I removed the blown caps and replaced them with the OS-CONs or UCC LXZ. The board POST's, so now I can move on with the rest of it.

In case anybody is interested, I actually calculated stuff to see if I was in spec according to THIS (pdf) document from AMD.

Re: Epox 8KRA2+ blown GSC

Are those Sanyos OSCONs or polymers? If it's the former, have the purple sleeves been replaced by bare metal/lacquer?

[Super Nade]

Re: Epox 8KRA2+ blown GSC

They are Sanyo OS-CONs. Sanyo no longer use sleeves.

Re: Epox 8KRA2+ blown GSC

all mfrs are moving away from the shrinkwrap sleeves.
btw oscon is polymer too.

[Super Nade]

Re: Epox 8KRA2+ blown GSC

Yep, conductive polymer. Their audio line uses some kind of organic material. I don't know too much about it. Maybe kc8adu can shed more light on it

Re: Epox 8KRA2+ blown GSC

Job's done! Now it is going to run memtest for 2 days straight before I ship it back to the owner.

Nice job!

What are the rest of the (blue) caps you replaced?

[Super Nade]

Re: Epox 8KRA2+ blown GSC

Blue = Chemicon LXZ.
Brown = Chemicon KY.

19 hours and not a single memtest error.
