Nichilons?

[trodas]

Sapphire mobos like the beauty PI-A9RX480:

...are using Rubycons (great choice) and Nichilons as the solid polymer caps.

So, my safe question is - is not the Nichilon just something like rip-off name for caps? Like the Rubycon fakes "Rulycon"

Anyone know something about the solid polymer caps and good brands of them?

Re: Nichilons?

hehehehe Nichilons. sounds like something out of Star Trek.

do you have pic of the logo.

yes they sound like Rulycon. good find trodas

Re: Nichilons?

Sounds like Rulycon, great find. Can we get a pic of the 'Nichilon'? Nice board.

Re: Nichilons?

See bottom right of the photo.

[willawake]

Re: Nichilons?

ok got it now. looks like it says nichicon though

[Rainbow]

Re: Nichilons?

Oh sorry, they also don't appear to be solid polymer caps... Any other photos?

[Chris1992]

Re: Nichilons?

They look like bare can lytics.

[willawake]

Re: Nichilons?

they are not polymers they just have no pvc sleeving to be more environmental. Nichicon HD series. I wonder if they changed the text and logo. Here is the one we are used to :



the current datasheet is no help it has them with sleeving

Re: Nichilons?

It appears that it still says "Nichicon". It didn't see "Nichilon" on those caps.

Re: Nichilons?

Looks like at least thirteen polymers scattered across the mobo. Or are they surface mount wet types?

[Rainbow]

Re: Nichilons?

I think that there are only 4 polymers in the VRM.

[willawake]

Re: Nichilons?

for polymers it has 4 oscon SP and two chemicon chip type
otherwise it has lots of teapo and nichicon UD chip type along with HD we already spotted.

nice to see they used heatsinks in quite a few locations. also interesting to see quite a few apparently tantalum caps.

overall though it is a pity about the teapo but it could be worse

Those are Nichicon HD series, as willawake said.. They're not particularly new, as i had a factory recapped KR7A-133R with a pair of those type in the CPU VRM.

I've also seen them on some Xbox motherboards.

Re: Nichilons?

Mmmmmkay, the used admited that he repeatedly did typo and they are Nichicons in fact So... beat him!

Not me, pls. Therefore the whole thread is pointless, eh

Sorry guys.

willawake - yep, they are a bit different, probably new design? But they key point is, that they aren't polymers
Now - what teapo? Where? I replace it ASAP as I got the mobo with Panasonic FM ones! Damn Teapo. Where?! Kill teapo!

[willawake]

Re: Nichilons?



Here are the caps to replace. I dont know what the two next to the nichicon HD are, perhaps also nichicon?

are you going to get some oscons to play with sometime? you can get them from waifong. it would be nice to put all oscon in vrm. they draw a red box on the board already for where you should put oscon. the ones i have not circled are the oscon sp.

Re: Nichilons?

Nichicon's HD series has been around for a while and seems to be the "ancestor" for the various H(X) types. The caps on that MB were made in April or May of 2005, however. I have a batch of HDs (16mm x 25mm) made 5 years ago that spell out "Nichicon".

Re: Nichilons?

willawake - aaaah! Bad pic!!! The pic show a pre-production board witch was send ("great" idea) to some reviewers and - this come as no surprise for BadCap users aware of Teapos - for some one them the board died and for few the caps blew out
The funny part is, that this make Sapphire switch to Rubycons and Nichicons for production baords and you can't find a single Teapo on this mobo now

Hopefully!
(sigh with deep relief) :

I provide pics in case there is interest when I got the mobo in my hands actually

[willawake]

Re: Nichilons?

hehe it is usually the other way around, they send the reviewers the good stuff.

you are right though x-bit labs board AND cpu was killed

At that point we were almost ready to state that there are no hidden traps in overclocking done with Sapphire PURE Innovation PI-A9RX480 platform. However, we were pretty puzzled with what happened next. During our stability test of the overclocked system, which we performed with Prime95 utility, the system suddenly shut down. And it wouldn't boot again, no matter what we did. The verdict was: mainboard death.

Luckily there was another Sapphire PURE Innovation PI-A9RX480 we had at our disposal at that time, so we could continue our tests, however, there were more consequences to this dramatic failure. Our investigation revealed that the mainboard died because of the failed capacitor in the CPU voltage regulator unit. We sent the mainboard back to Sapphire for further examination, but nothing could help our poor CPU at that point. It rested in piece, too.

Re: Nichilons?

The "usually" seems to get reverted a little there

Before I give a final rating, let me share one more experience that I had with this board... It died. I had finished testing, finished overclocking and brought it back down to 400MHz, and was typing this article when it Blue screened on me. After that it would not reboot no matter what equipment I had installed. I tried for an entire day to get it to work again and switched CPU's, RAM, and HDD's, but it wasn't having any of that.

IMHO Sapphire is trying to knock theirself out of the bussiness

Such problems are nonexistant among even crazy overclockers with production boards based on quality caps. Another very fine "BadCaps (tm)" case.
Well, one actually recently killed his AMD 64 X2 3800+ in this mobo, but it was not the mobo fault, that he raised the Vdimm voltage to 3.7V while leawing the Vcore stock low, so the difference between the voltages (ram controler is on die in AMD 64, remember) killed the CPU. The trick is to keep the Vcore high, when going in such insane and unsafe things as trying to fry the ram with 3.7V ...
Mobo support up to 4.4V, but I dubt the AMD64 die could handle that - 1.40 and 3.7 is difference of 2.3V witch killed the CPU. Now assume that we go safe (keep the difference at max. 2.1V) and then we have phasecooling and fry the CPU with 2V Vcore (a bit insane for AMD64, common for AXP, however) - then the max. Vdimm voltage is 4.1V exactly.
Setting 4.4V kill anything you can insert into the socket - witch even remotely looks like a CPU

Re: Nichilons?

IMHO we wil see more of this as the procs get faster and if they continue to require more current. It is not only the current actually it is the processor moving from idle to load in a huge step repeatedly. Perhaps the resullt - good polymer caps for everybody eventually. Failure out of warranty ok but failure in reviewer's hands tsk tsk..... personally though that board may have design probs. perhaps the good caps will compensate. I am sure you will test the crap out of it trodas.
