Re: *** Class Action Lawsuit Against Abit ***
I opted for the AI7 (Socket 478) after reviewing the available options that Abit presented. It seems like a better upgrade path than Socket A, has SATA-RAID, and seems pretty highly rated.
I will pick up a 2.66GHz-3.06GHz Celeron D or a used P4 processor for hopefully around $50 (with HSF) and some PC3200 DDR memory (I've seen 512MB for as low as $20 AR). So, for less than $100, I can upgrade my old 900Mhz Athlon system to about 3x the horsepower.
I may have to upgrade my power supply, as I can't remember...

Re: *** Class Action Lawsuit Against Abit ***
I just got the following email from Abit regarding the repair of my Abit KT7A that was sent in last month. The irony is that I had already recapped the AGP area and the board was working fine -- I just wanted the 2-year warranty and for them to put on new caps where I didn't bother.
Anyway, Now I have to figure out what board to swap to (and my PC133 memory is now useless). Any suggestions from the list below? I have a Athlon 900 processor and 2 sticks of Crucial PC133 256MB. My first thought was the NF7-S2G, but I'm also...Leave a comment:

Re: *** Class Action Lawsuit Against Abit ***
Here's a quick update on the Abit settlement:
About a week ago, I received the packing materials to send my Abit KT7A in for the class action repair. Abit included a protective bag to slip the motherboard into and a packing slip. I glanced at the instructions (I will need to read them again) and they said to drop off the motherboard and packing slip at any UPS (I think) and they will box it up and ship it at no cost to the consumer.
I plan to pull my KT7A out this week or weekend and send it in. I will...Leave a comment:

Re: Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
Okay, I checked the voltage of the CR2032 battery while installed in the P4S800 motherboard.
With 120v AC cord plugged in, the CR2032 read 3.02V.
With 120v AC cord unplugged, the CR2032 read 2.98V.
My guess is that 2.98V should still be enough to run the RTC, right?
I didn't have a scope available last night to see if the 32KHz output differs depending on whether the 120v AC cord is plugged in or unplugged. That is my next task...Leave a comment:

Re: Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
Duh!!! I should have remembered that the positive terminal is on the upward facing side of the CR2032! Good call, Rainbow.
Yes, I did see one of those barrel canisters near the battery, but there was no writing on the side that was facing up so I didn't know if it was a crystal or what. I will try to check and see if it is oscillating when 120v AC is removed.Leave a comment:

Re: Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
I checked the CR2032 battery over lunch and it was 3.0v so it hasn't been drained yet. I don't know of a good place to measure the voltage of the battery while it is installed, though.
I Ohm'd out the battery socket (with the battery and 120V AC removed) and got aroun 580 Ohms. I realize that's only an estimate, but it shows there isn't a direct short between BATT and GND. And doing the math: (3 volts / 580 Ohms = ~5mA). That seems like a reasonable load to me (anybody know anything different?)....Leave a comment:

True, as long as it's not an early symptom of a more pronounced failure -- plus it's not supposed to work that way.

Re: Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
Thanks Rainbow,
I'll look for the crystal. I know exactly what type of crystal you are talking about.
That's also a good idea to Ohm out the BATT to GND connections with the battery removed (and power disconnected) to see if there are any low impedance paths I need to troubleshoot.Leave a comment:

Re: Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
Yeah, his new computer is definitely a DREAM Machine!
And like I said, this P4S800 system is Awesome to me, since it is going to replace my Athlon 900/KT133A that I build back in 2001, once I get all the kinks worked out of it.
If worst comes to worst, I'll just have to buy a new(er) Socket 478 motherboard but I don't think it will come to that (at least, I hope not).
That's why I'm begging and pleading for a bit of help so I can track down this reasonably...Leave a comment:

[Reply for Chris1992]
The system is probably 18 months old, which is very NEW for me but OLD for the guy I got it from.
[Reply for kc8adu]
I bought a brand new CR2032 and used a voltmeter to check the voltage before installing it into the motherboard. It was around 3.1v. I can pull it out and check it again today.
If the battery is low today, what could be killing it? There should not be anything pulling that much draw on this battery, especially...Leave a comment:

Asus P4S800 RTC won't keep time? (and "do you have a schematic?")
I recently got an older pc system with an Asus P4S800 Socket 478 motherboard and a P4 3GHz processor. The system runs rock solid but has one quirk: the RTC stops keeping time any time the PC is unplugged from 120v AC.
When I first got the pc, it had been stored in a closet for months and the CR2032 CMOS battery was depleted, so I replaced the battery. Now the CMOS is retained when I unplug the power so that part is working.
But if I unplug the power cord from the pc for 4 hours and then plug it back in, the RTC will loose, you guess'd it, about 4 hours.

Re: *** Class Action Lawsuit Against Abit ***
I talked with one of attorney's for the Abit Class Action Settlement and he said that it was just finalized in the courts in the November/December 2005 timeframe. It is his understanding that Abit won't start sending out the packing materials to ship your boards in until after the close date of Feb 15th, 2006.
Sadly, the attorney's are just the middle men/women in this so he could not give me any details as to exactly when Abit would start collecting the boards or how long it will take to get them repaired.

Re: Help selecting replacement caps for ECS K7VZM with bad G-LUXON caps...
Recapping complete, and the K7VZM board is alive and running perfectly stable so far...
Notes from the recapping (for others who may be recapping a K7VZM):
1.) I selected the Panasonic FM series caps for my recapping. They seemed to have high ripple current (low esr). (See NOTE below.)
2.) NOTE ABOUT PANASONIC FM 1000uF 6.3V:
I read the datasheet wrong for the 1000uF 6.3v Panasonic FM caps. I needed 8mm diameter 1000uF 6.3v caps and Panasonic's 1000uF 6.3v...Leave a comment:

Re: Help selecting replacement caps for ECS K7VZM with bad G-LUXON caps...
willawake,
Thanks for the note. I should have been more specific. The original caps by the CPU are 10mm 2200uF based on my crude inch ruler measurement, so the new ones will be the same diameter, only taller by 5mm (20mm vs 25mm).
In an effort to zero in on the bulging 2200uF caps, I didn't post a picture of the entire board, where you would have seen some of the 8mm 1000uF caps down around the PCI slots and elsewhere. The 1000uF aren't leaking yet, but will be replaced while...Leave a comment:

Re: Help selecting replacement caps for ECS K7VZM with bad G-LUXON caps...
Thanks again for the helpful responses.
For the sake of others reading this thread, I have narrowed my search to the following brands/models of 2200uF 6.3V capacitor for the ECS K7VZM:
Nichicon HE, 1650mA ripple, 4000+ life, 10mmx25mm
Chemi-Con KZE, 2150mA ripple, 1000+ life, 10mmx25mm
Panasonic FM, 2470mA ripple, 3000+ life, 10mmx25mm
The Chemi-Cons are the cheapest. Panasonics and Nichicons are pretty much even on price, and both are about 30% more...Leave a comment:

Re: Help selecting replacement caps for ECS K7VZM with bad G-LUXON caps...
Thanks for the quick and detailed response.
Digikey also sells the Chemicons for much cheaper than Nichicon, but they didn't have a data sheet to look over, so I was worried that the Chemicons were inferior knock-offs. Are they of equal quality to the more name brand (at least to me) Nichicons and Panasonics?
Thanks again.Leave a comment:

Help selecting replacement caps for ECS K7VZM with bad G-LUXON caps...
System Info:
ECS K7VZM v1.0
Duron 800MHz
256MB SDRAM (PC133)
Diamond Video
I am looking to replace the capacitors on my nephew's older ECS K7VZM motherboard. It stopped booting recently -- it will power up to the BIOS but will not boot much beyond the hard drive detection. That's when my sister called me in. (Fun, huh!)
I found eight of the twelve G-LUXON 2200uF 6.3v 105C caps in the supply area have bulged. There are also seven G-LUXON 1000uF 6.3v 105C caps that I will also likely swap out, even though they have not bulged yet....
