Re: SV25/FV25 problems after recap

Now I've run prime95 for about 1,5 h with the 1.4GHz P3 without errors. Seemed good. Then I rebooted the computer... but than it hanged again in the Verifying DMI state... Rebooted - and then it was OK... rebooted again - still OK. Very strange...

If you google for "sv25 dmi" then you will get very many hits. If you read through the found pages then you'll see that this problem seems to be derived from bad caps. So probably my problem have the same cause... we'll see if it's so when I get the new ones. Maybe I've...

Re: SV25/FV25 problems after recap

Now I've done some more testings... I've tested the MB with several different CPU's - with different results. Every CPU is known to be working before the testings.

The CPU's I've tested with is two different tualatin celerons (1.2 and 1.3GHz), one tualatin pentium iii-s (1.4GHz) and one coppermine pentium iii (733MHz).

The celerons do pass the "Verifying DMI Pool Data" message (and starts to boot the OS) maybe 2 out of 8 trials. The 1.2GHz (SL656) seems to be slightly better on this compared to...

OK - can that be fixed?...

Re: SV25/FV25 problems after recap

No, actually it's more capacitance now than before. I think you misread the figures.
To upper the values shouldn't be a problem as far as I know... but maybe that's wrong?

I have actually ordered new caps (Samxon) with "correct" capacitance and voltage - we'll see if that solves the problem.

I bought a SV25 a while ago. After some time I discovered that many FV25 MB's have had problems with bad caps... but mine was still running just fine. But to be safe I decided to recap my board anyway.
I ordered a kit from Topcat and then recapped the board with the received Rubycon caps. Everything seemed fine - nice soldering, correct polarization and no visible damages.

Now to the problem... after the recap I now have frequent problems with that the computer hangs in the "Verifying DMI Pool Data" state.
BUT, if I disable the L2 cache - the computer boots...
