I've acquired some old motherboards noticed one has all blown caps looks like an (Asus nforce 6100 chipset). I thought would be fun project to replace with solid state caps.


So anyone ever try this or have pics ? :)

I've done it a lot... well.

Do not replace epectrolythics with solid state. The VRM is not designed to work with it. Without math and VRM datasheet it is not recommended to alter it.

Just use proper and new 105C

I have almost completed a 939 motherboard removing all electrolytic & going all polymer. CPU clocks much higher, but when it comes to Prime95, I have gained around 1-2 MHz over the old capacitors. Each capacitor is hand picked, ie it is tested first with two ESR meter.

Motherboard mostly fitted with Nichicon PLE series.

We had a member here that used to run post after post of exactly this. Cannot for the life of me recall the user name though. Off to search the forums as his threads may have some insight.

It was trodas, but it appears the images he hosted have since been removed :(

Be aware if you change capacitor type, you can run into trouble like I did. What I found out is, on old motherboard manufactures skipped or left out some capacitors. I filled this in including ceramic capacitors. I have processors here that refused to do 3Ghz, but now all of a sudden it can do 3.1GHz, almost hitting 3.2Ghz., but it's only good for benchmarking, not everyday computing. I must admit, I did change resistors around the controller, as I want a very efficient VRM..

My first oem motherboard died because off one, i fucked up that one place because i soldered first time.
You just need correct temperature whit good solderer should not be problem finding it in local DEPO and some caps from Ebay. After that you even will be possible to solder some led strips in your car...

I did a board recently, a non-working DFI LP UT nF3 250Gb (bulged/leaking caps, ect.), I replaced all the VCore and various other caps around the lower half of the board. VRM works great now but it still doesn't post, no error code beeps either.
Need another cpu to try as I only have one and I think it's dead from trying to run the board before recapping it. :oops:

Would be nice to get it working, it's in like new condition with the original box and accessories still sealed in their bags.

Proof. This processor would not do 3GHz with old capacitors, now hitting 3.2GHz with more Hardware Modification to come. This motherboard was also call garbage on overclock.net.

I think but not sure this benchmark grabs top spot for "Air Cooled" for this CPU on HWBot website..

Nah. 3.1-3.2 is about normal for a good chip on air.
That board is most definitely not an enthusiast board.

Your name looks familiar to me. Where do I know you from?
I ask for help with BIOS for my motherboard, but AFAIK there is no processor out there that support 1 clock cycle. I have gathered vast amount of information & new way of cooling. That processor is using a IHS directly soldered to the heatsink under high pressure, it's now standard here for over a year.

But there's more to come. Me being kick out of that thread was not a good idea by the other users.

Ahhh......I remember now.
939 thread at OCN. SPD editing cheap ram.
That explains a lot.

Terrible board... terrible caps... not surprised it helped get it up a bit...


Anyway, to the OP, I dont see the point of a recap, personally. I can find better things to do with my time. :)

I used to recap those Dell boards that were notorious for bad caps all the time back in the day. But now my carpal tunnel in my hands makes it hurt too much to do a lot of soldering, so I haven't done it in several years.

also keep in mind clearance issue's around the socket, so you may need to order same sized caps. I've done it on GPU'S then realized the cooler would not clear the new taller caps, what I get for being cheap not ordering new one's.
Also note the side of the cap spot will have white on it, showing polarity make sure not to mess that up........

That's only true if you're trying to OC to high heaven. If you're running stock and needed reliability, that board was a good choice. Not everyone is a mad-hatter overclocking fiend.

Things like this can save money(which for some people is the same as time), can be interesting and a lot of fun.

Recapping a board isn't bad, just takes time and patience. Redid a few AN7's awhile back that had been dead but got them all going again in the end. I too have to say use the same cap types that were in and you should be fine once done.

But there's more to come......
God help the admins.......

The next frequency up on HWBot is 3325, that can't be on air can it? if so I am on top for air cooler.
Uhhh........ Riiiiight.
Unsubscribed too because this ain't gonna end well.

What some users may not realize, some motherboards maybe under performing by poor choice of capacitors by the manufacture of the motherboard.
Look what the motherboard is doing now. it fairly high up the chart on HWBot sitting behind those users on LN2 & other type of cooling. It now feels different.

Am not into high end overclocking, I did that test to see if anything has changed & that modifications are going in the right direction.

I still have 9 capacitors to change over, but it will not change performance as these are around the PCI slot & audio chip. I also have 3 ceramics capacitors to add-in around the north & southbridge.

ok...Thanks for sharing what we already know (first part). But considering what the OP is doing (or what hes brining up anyway)....well, surely you can figure out how relevant that point is to me. Also, if reliability was a concern, i wouldnt have gone with a budget board using weak vrm and no heatsinks on it. So...that doesnt make much sense to me, lex. It wasnt a great choice for that either. ;)


Anyway, cool for you guys... enjoy recapping!! :)

see above. Few care to take the time to do something like this when we are able to spend $30 more for a better board. Literally that is less than an hour's pay for me. Time spent vs gains simple isnt worth it (to me) to sit there for several hours recapping a cheap arse already functional board.

You go with your bad self though. :)

You might need a good iron, boards have lead free solder and it won't lift easily.
