Another poorly done recap job

Re: Another poorly done recap job

I am very sure I installed thermal compound under the heatsink and it is placed correctly.
It gets very hot,along with the northbridge heatsink,but I think the NB heatsink gets hot because it's very close to the HSF.

Re: Another poorly done recap job

Still,the CPU runs INSANELY HOT(81-85*C)yet it doesn't die at all.

Sounds like either sensor error (if you are absolutely sure the heatsink is on the right way and there is thermal compound under it) or something is wrong with the heatsink installation and the CPU is thermal-throttling.

Re: Another poorly done recap job

I couldn't find any series written on that TEAPO.Anyways,I couldn't solder the cap to the video card.Strange thing is,the card still works!
Anyways,I scrapped on recapping the A7V8X-X and bought a complete pack consisting of a P4P800-VM (T-Systems OEM,caps are Rubycon and Panny everywhere!),a 2.4GHz Celeron D,and 4x 256MB DDR400 Kingston RAM.
I reinstalled 7 on the old 10GB HDD,as it wouldn't boot on the new system.Also,reflashed the BIOS to the latest retail BIOS(original was reading T-Systems BIOS 1015 LHM),but that after having a hard time installing 98 that didn't work on my 8GB old HDD,and ended up installing XP SP2 on FAT32 so I could access the drive from DOS.

It depends on what series the Teapo was. Ruby YXG are on par with Nichicon HE and Chemi-con KY.

Re: Another poorly done recap job

Well,that's all I have.
When I'll have time I'll add the last 2 caps on the board,and see if it boots.
Also,is it good to replace a Teapo with a Rubycon YXG?

Re: Another poorly done recap job

HD might might be perfectly fine for a P3 board, but I wouldn't use them for anything later.

Generally yes, but it also depends on the motherboard, too. For example, I have an ECS P4IBMS motherboard - that thing has IIRC either 8 or 10 cap spots on CPU VRM low side - all meant for 10 mm caps. The original caps in there were G-Luxon LZ, 6.3V 3300uF, and I believe there were only 6 or 8 of them on the board originally. A 6.3V 2700uF Chemicon KY in 10 mm diameter can already exceeds the specs of those G-Luxon LZs by a decent amount (0.031 Ohms ESR and 1910 mA ripple for the KY vs. 0.043 Ohms and 1400 mA for the LZ). So technically, I could have used just Chemicon KY (but of course, I used used 4x Nichicon HZ 6.3V 2200uF and 4x Rubycon MFZ 6.3V 2700uF instead because I have too many. Overkill for a 60-80W TDP Willamate/Northwood P4 CPU... maybe ).

Pentium 3 boards generally had much lower power requirements for the CPUs, and thus didn't require the caps to be as low ESR as subsequent boards. HD might might be perfectly fine for a P3 board, but I wouldn't use them for anything later.

That dais, though, they are NOT a suitable replacement for KZG, as they have a higher ESR. The Sanyo WG caps are fine, though.

ASUS used them on the CUSL2-C,so I don't see anything bad in using them.All are of the same ratings.Same uF and same voltage.

I noticed that a PS2 50W PSU was posted on the PSU build pictorial.I got the same PSU and a Matushita built PS2 PSU,and I was surprised that on the Matushita,there wasn't any Panasonic cap,but all caps were Nippon Chemicon.

Nichicon HD was never affected by the HM/HN disaster. All Nichicon HDs are safe.

That said, though, they are NOT a suitable replacement for KZG, as they have a higher ESR. The Sanyo WG caps are fine, though.

Re: Another poorly done recap job

Right.
All the small 1500uf 6.3v caps were Chemicon KZGs.Now I use 3 caps for that ASUS A7V8X-X recap,all with the same specs:Sanyo WG,Nichicon HD (2000 datecode,safe) and some S.W caps from a Slot 1 board that was shot.

Re: Another poorly done recap job

...(I let you all guess what company made the 1500uf 6.3v caps on it.The name starts with N and ends with -on)...

Also,no,it's not Nichicon. The name of that cap is made of three words.

Nippon Chemi-Con

Re: Another poorly done recap job

Nah...I forgot about that old card.It has just 64mb VRAM,and I don't think it is supported under Windows 7.

Also,no,it's not Nichicon.The name of that cap is made of three words.

Re: Another poorly done recap job

The only thing I was able to recap until now and have it look good was a old half-broken 64 nVidia FX5200 video card,on which a cap broke and I put a TEAPO I had around in there.It was outputting garbage though,because I broke a SMD component off (ceramic cap most likely)
Was still fun to try and see if it boots.

Make a new thread and post some pics. Graphics cards are fairly straight-forward. If you're getting garbage on the screen both in 2D and 3D, you might have knocked off an SMD resistor for the RAMs. Repairable, usually. If it's a SMD ceramic cap, even easier - just borrow one from something dead.

Nichicon?

Re: Another poorly done recap job

KZG and HEC caps on a GX270?How didn't they blow up like fireworks on the 4th of July?

momaka,I have to say,the soldering job in there is billion times better than mine.

I'm going to try and recap my A7V8X-X to see if it boots (I let you all guess what company made the 1500uf 6.3v caps on it.The name starts with N and ends with -on)and also my Radeon 7000 (this one will run with 2 different 1000uf caps:1 Teapo & 1 Rubycon YXG)

Re: Another poorly done recap job

crappy caps... but soldering still not as bad...

[momaka]

Re: Another poorly done recap job

This time, it's a GX270. It's not as bad as some of the others I've seen on this forum, but there's plenty of room for improvement.
...

What the HEC?!

Yeah, that's not a very good recap job. But you are right - at least they used flux and the soldering doesn't look terrible. Mind you, mine looked worse... but I only had a 35W iron at the time and a heat gun. This is my ghetto recap, if any of you remember:

Here's the whole thread too:
https://www.badcaps.net/forum/showthread.php?t=20102

Eventually re-did it though. Changed the 1000 uF Nichicon HMs on the VRM low with more Chemicon PSC polymers, along with that red Apaq polymer. Still a work-in-progress, though. I have a 3 GHz Press-hot waiting to go in that machine .

The first one to go is usually the one in between the DIMM slots and AGP slot (probably because the two MOSFETs next to it get hot enough to discolour the PCB under it.

Yeah, that MOSFET runs insanely hot. Last time I checked it with my fine-point type-K thermocouple, it was running well over 70C case temperature. The cap next to it (Panasonic FJS) wasn't much cooler either. I think I might change it for something else too. Or add a heatsink on that MOSFET. Foxconn did a crappy design here.

Re: Another poorly done recap job

What's the green slot? Doesn't look like PCI-E, and I thought AGP was always brown?

AGP.....Dell has to be different....but I've seen them all kinds of rainbow-like colors...

Re: Another poorly done recap job

I'm pretty sure it was a P4 2.8 with a Northwood core.
