Re: Killed my Asus A7V266-E? Need advice
It's a Maxell CR2032 battery from Maxell Hitachi Ltd., it also has a number code 47 printed on it. On my newer Asus boards they are using KTS CR2032 battery indeed.
Thanks, that's intereting to know, I never know that it can be a problem. In my case a litte bending and cleaning really helped, I will see how long that holds....

Re: Killed my Asus A7V266-E? Need advice
Yes, I guess so, I was searching and reading about internal resistance of batteries, untill I found a new one to try, it made no difference at all. I did some cleaning and bending, no sure which actually helped or maybe both. Now I'm actually still using the original 18 years battery on the board! As I wanted to see if it's indeed just bad contacts. Probably because I rarely turn off the PS, so it still has 3.1V, but I think it's still amazing that it doesn't seem to lose/leak it's charge at all....Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Yes! Finally I have no more troubles! Yesterday I put everything back together, luckily it went fairly straightforward, Windows booted normally like I did nothing!
Only except one thing, for some strange reason one of my Voodoo2 has been redetected and required a driver installation again. I wasn't even sure which driver I used for the other card. and it did take me a few attempts to get that card to work too, it always appeared disabled in the device manager. I tired to boot into safe mode to do something there and...

Re: Killed my Asus A7V266-E? Need advice
Hi guys, after many boot ups I finally pinpointed the problem, and probably solved it too! Cold start today after some 36+ hours was successful, everything appeared to be normal, so I stretched my head but was still happy. Then I shut off the PS to connect some more cables and case fans to the board, at the next boot CPU was set to some strange frequency. It turns out that the CMOS doesn't keep it's settings any more. I think that has caused the problem at the previous cold start after 24h too, because I did shut off the PS and worked a little...Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thanks for your reply! I did leave it off over night the first day though, it was still OK in the next morning, so I thought everything was fine. Maybe it was not long enough, I will keep it off for more than 24 hours again and see how it goes. Next I will recap one of my boards completely then. It's very reassuring to read what opinion about my soldering
And I will work to get better.
Thanks! That's very reassuring to know too! Thought I was quite gentle, but the photo really shows otherwise:...Last edited by delide; 05-29-2020, 08:03 AM.Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Yes, it's still the original battery but it still has 3.1V! I measured it both on and off board, it's the same. It should still have some years left.
This time the boot problem first reappeared after I left it off(onboard power LED still on) for more than 24 hours, all previous boots was always OK. I think I might not have fully cleared the CMOS last time, as the manual just isn't clear at all, now I have left the jumper closed for long enough time. I shall test again on this Sunday, it's really strange.

I think I'm getting a bit paranoid here, tested with remaining cap, the legs are very strong. There should other reasons that the caps appear to be tilted closer now....Leave a comment:

Yes, time absolutely flies, really feel that both we human and the hardwares could use much longer life span!
Your recapped board looks really nice! I will study that thread carefully, when current trouble with mine finally go away....Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thanks! But very unfortunately I spoke a bit too early, I tried to power it on moments ago, the nothing came back again! :-( But fortunately, it was straightforward this time, I just reset the CMOS and it boots normally again. So there is probably still something strange going on, if not the CMOS maybe the VRM still have problem?? But once booted up, the Memtest ran without any trouble. Anyway I guess I have to keep the patient on observation for a couple more days, before I can resume and to put everything back.

Re: Killed my Asus A7V266-E? Need advice
Here is the story so far, if anyone has boot problems with the board it might be helpful.
With the new CPU installed I checked the wiring, jumpers and everything, even prayed and then turned it on, it was still the same, fan spins, no beep. So I cleared the CMOS and checked everything again, and again still nothing. I repeated the whole process quite a few times, but it's always the same nothing! At that point I believed I was working on a still fresh looking but pretty dead board... I was running out of ideas, but just in case...Last edited by delide; 05-28-2020, 09:28 AM.Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Wow, I can recognize nothing from my photos! But yes, I read everything you guys said in that thread many times. As I understand it, for his board it's OK to just replace the 4 3300uF caps, somehow I went stupid again, and assumed my board would have the same brand/type of caps as his, so I actually never did check mine and just replaced the same 4 caps, as one of them near the MOSFET just bulged very slightly.
By the way the board is from my build in 2002, I used the PC for about 6 or 7 years, after that I...Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thanks for your reply again! I will certainly check those remaining caps! For now I have good news, I got it boot up successfully! It was totally the opposite of straightforward, there were all sorts of strangest behavior, it took me countless boot attempts but then all problems disappeared suddenly! I was so happy to be able to enter the BIOS that I booted a few times more:-) Also ran a few passes of Memtest86 yesterday, so far so good! Thanks for your advices! Will post how it went shortly.

Haha, indeed, I used to think it's an economy version of the deluxe version, so I always went for the -E, till I totally get lost in the new generations.
A7N8X-E seems to be very nice indeed, I thought about it as replacement, but then I read that the Nforce chip has trouble with DOS emulation of PCI sound card and gave up the plan....Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
I've attched more photos of the entire board, thanks for looking!! Also attached a photo of the CPU, at the top left corner you can see the mark of the "eruption", pointed toward the VRM as well, certainly back up momaka's observations! BTW the die itself still look quite normal too, not that I will put it in again, BUT, just maybe I was not the latest/the last idiot to have fried a XP CPU then
guess we will never know
An other CPU is on the way, I will then try to boot it up, this time I will certainly...Last edited by delide; 05-23-2020, 02:07 PM.Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thank you very much for your advices, yes, I really should just touch the heatsink after I removed it! I guess my brain got shorted for a moment before the CPU did!
The PSU is fairly new, it's a bequiet S9 400W, so it should be OK. Yes, the caps feel pretty solid when I tried to move them as you said, but I will try to refill the joint if I got the board to boot up again. The other joint has too much solder indeed, I rarely do soldering at all, it should still be OK? That place actually has a 8 shaped...Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thanks for your lengthy answer! You must be right! It did puzzle me, where did that smoke came from, I looked at the CPU now, it looks like melted sealant or glue(the stuff around the edges of the die) shot from one corner to the left of the board, it probably hit the coil and made it looks like the coils smoked. There was indeed a smell, should be just the CPU then, I can't tell, it must be the first time I burned something outside of a oven...
I indeed only replaced the 4 HM ones, which are the biggest and...Leave a comment:

Re: Killed my Asus A7V266-E? Need advice
Thanks for your quick response, I attached some photos of those area. I don't see visible damage, the choke that smoke doesn't look different either. But now I see that one joint is still partially uncovered(bottom3 top right), should have bought much thinner solder wire. For now the VRM still seem to work though, as the VCC at the socket looked good and accurate, on my multi meter at least. I don't have a scope. Still I don't want to give up yet. What are your thoughts? Thanks!...Last edited by delide; 05-22-2020, 11:25 AM.Leave a comment:

Killed my Asus A7V266-E? Need advice
Hi guys, I have troubles after recapping my board. One of the 4 caps on the output side of the VRM is slightly bulged, otherwise there was no issue with the board at all. I read the other thread about polymodding this board, it was really helpful! So I went on and replaced the 4 caps with the NCC ones too. I used my spare XP1600+ to test first, as I do not want to fry my CPU, it's a nice 1700+ that can run 1.35V and very high clock too. It took me at least 3 tries to get it finally boot up into bios(I was anxious and mistaken the power LED and then power reset for the power switch wiring at first
),...
