Most amazingly I've not broken it and the mobo works OK after the recapping .

Nice job man, it looks great Those are good boards, and very reliable. Those heatsinks will help too!

Re: ASUS P4P800 recap

Thanks. I've also beefed up the homebrew VRM heatsinks:

Fancier versions like the SE or Deluxe have three mosfets per phase ...

... but the base model P4P800 has to do with only two per phase, and they get fiercely hot while feeding an OCed Preshott.

Re: ASUS P4P800 recap

whoaaaa.. you are the real man bro !!

You are full of idea. I have read your ghetto mod thread and piece of junk on PSU thread. Now you are the winner. This motherboard looks shinny and great after recaps. congrats !!

I have recaps my motherboard too today, but not all caps, just 2 bad caps that i changes. this is my first recap too. pin trick from recapping faq works very well. After recaps, my motherboard didn't show any hang problem and run likes a charm.

If I am not wrong from I see, the caps before recaps is UCC KZE KZG as you said? okay. I am understand with you statement, so KZE with Nichicon HM and KZG with Nichicon HN.

Re: ASUS P4P800 recap

Thanks Senz . There are some typos in the list above, the correct roster is:

· VRMin · · · · · 4x United Chemicon KZE 1200uF 16V 10mm ======> 4x Nichicon HM 1800uF 16V 10mm
· VRMout · · · · 7x United Chemicon KZG 1500uF 6.3V 8mm ======> 11x Nichicon HN 1800uF 6.3V 8mm

· Smaller caps · · · 16x United Chemicon TMZ 1000uF 6.3V 8mm ===> 16x Panasonic FR 1000uF 6.3V 8mm
· Smaller caps · · · 10x unknown 100uF 16V 5mm ============> 10x Rubycon ZLH 100uF 16V 5mm


I'm writing this from that mobo, working like a charm.

Re: ASUS P4P800 recap

Ha! I need to do that VRM Heat sink mod to my old Intel D945GTP motherboard. The VRM on that board gets ridiculously hot with the CPU I'm using with it (a 130W Pentium D 830)

Re: ASUS P4P800 recap

The taller the heatsinks the better C_hegge. Thus the tips are put in the breeze and cooling is improved.



I ghetto-modded mine by cutting slices from Slot-1 CPU heatsinks .

Re: ASUS P4P800 recap

Sometimes I ask myself this ghetto mod would give bad effect from fan that vibrating, maybe just a little vibration, but I am too afraid makes this.

my Northbridge and Southbridge didn't have any fan, just a small heatsink. I have ever think attach salvaged fan from older Pentium motherboard if the size of fan compatible with heatsink, but until now I am not doing it yet, maybe this mod would damaging my board as I think.

How your experience TELVM? how long you are using this board with mod, any problem?

Re: ASUS P4P800 recap

I'm not sure which fan do you expect to vibrate Senz . The small 40mm fan on the northbridge heatsink in the pic above was a test, I've removed it since for there is no real need for it. Comp works fine.

Re: ASUS P4P800 recap

Good job with the recap, and amazing "ghetto"-modding as usual !

By the way, you can keep those KZE caps for recapping power supplies or other boards. KZE is reliable. KZG and KZJ are the problematic ones.

Re: ASUS P4P800 recap

Yep I've thought about that, but ain't the 0.022 ESR of a 16V 1200uF KZE too low for PSU output filtering?

[momaka]

Re: ASUS P4P800 recap

Should be okay. Some PSUs will take it, others won't. I know that some older Sirtec half-bridge PSUs really hate low ESR caps - they "whine" (pun intended) when you put one such cap on the 12V rail. If you have a few Bestecs or HiPros around, though, those will work with almost anything.

I think Deer/L&C are quite flexible too.

You're right, Bestec/Hirpro/Deer seem to not be very picky at all when it comes to replacing caps. c_hegge even did a full polymod on a Hipro HP-D3057F3H with fantastic results, pretty impressive!

As for reusing those KZE caps, won't their voltage be permanently "tuned" to the voltage they were running at while on the motherboard?

didn't your northbridge have a small fan?

okay, so you just makes a test. I just wondering those fan are original from manufacture or modding fan

Re: ASUS P4P800 recap

Original P4P800 don't come with any fan on the northbridge, that 40mm Scythe Mini-Kaze was a mod I was testing during the pics. As it had no effect on the RAM OC limits, I removed the fan.
