Only thing that needed replacing was the dead BR2350 with a CR2032.

BRxxxx is rechargable, CRxxxx is not. Be careful!

I think that's the LiR-type that's rechargeable. I've looked everywhere and can't find any information about the BR-type coin cells as being rechargeable. I have a cross-reference sheet that shows a CR2032 and BR2032 (same as BR2325, just a smaller diameter and thicker) as interchangeable as well. Also, the cell would have "rechargeable" stamped into it.

Are BR2032 and CR2032 the same?
However, there are two main models on the market today: the CR2032 batteries and the BR2032 ones. The main difference between these two types resides in their electrode. While similar, the BR2032 uses carbon monofluoride as the positive electrode. The CR2032 uses manganese dioxide for the positive electrode.

Very interesting. I've gotten some bad information on this from somewhere then.
Thanks!
(At some point, i was actually trying to find out, if there is a CR2032 sized rechargeable battery, so one doesn't need to mess around with diodes or removal of some resistors for example...)

There is. It's the LiR2032 - https://batteryspecialists.com.au/blogs/news/ … atteries-cr2032

Hopefully that'll clear things up. 😀

For me junk is literally that, a part that is so bad that it's best to bin it (like parts that are not just defective themselves, but also kill any hardware it is installed in or are just plain dangerous to use).

Like my recently deceased Gigabyte motherboard which is almost at that point. It still starts and soft-resets, but won't ever POST successfully anymore, but I did notice it does still recognize when all the memory slots are left empty so I could still use it to test dodgy DDR3 memory modules.

Do not junk that mainboard yet - it's not dead! Like I said, there's a known issue with gigabyte LGA1150 and LGA2011 boards of that generation corrupting CMOS.

Try this:

- remove the CMOS battery
- power the system on
- turn the system off by holding the power button for 45 seconds (50 to make sure - it's important, this triggers a soft CMOS clear on gigabyte boards, just like on laptops!)
- put the CMOS clear jumper in the "clear" position and wait 10 seconds
- power the board on - it should not POST because of the Clear CMOS jumper
- power it off by holding the power button for 45 seconds again
- wait 10 seconds and turn it back on - it should POST. Put the CMOS battery back in while it's running. If the RTC battery holder is under your video card, then put it back in before this last step.

If that didn't work, the actual EEPROM is corrupted and you can re-flash the bios using a thumb drive - there's a how to in the manual. Like I said, my brother in law had a Z77 gigabyte board that did this randomly - a CMOS clear by the method I described above usually worked, and when it didn't he could re-flash the bios using a thumb drive. At one point Gigabyte released a BIOS revision for this board and it stopped corrupting CMOS.

I do have one dead gigabyte board - a late model KT400A. It has a short someware. It was working when I stored it, it's possible some crud got where it's not supposed to be or a capacitor dried up and shorted. I did like their KT400 and KT600 boards - they were among the few boards that let you select the CPU multiplier in BIOS. Not all GA boards with this chipset will let you do this, but the fancier ones with the golden northbridge heatsink and active cooling will. Great for pairing with an Athlon XP-M or Geode.

Darn it, if I knew these steps earlier I might be able to rescue the two GA-K8VM800M I had. 🙄

7 bucks for all this

i wanted this board badly because it supports up to athlon XP 2600
also has the P4 power connector
and also has an empy slot for ISA, that i can add it

with a pioneer dvd-rw and a 9400 gt graphics card

That's a fantastic deal. That MSI board will make a great platform for some retro fun.

Sadly it lacks the ISA slot.. I hate when they have printed the f**king ISA on the PCBm but yet no one bothered to install one... Not sure if someone try, can solder ISA slot there...

Cheers. I've tried looking for info on this, but have been unable to find anything useful except the standard troubleshooting stuff which i already spend a couple hours on until I decided to throw in the towel.
What you're describing seems like a thing I can try. It's indeed an LGA 1150 board though unfortunately I've already since completely dismantled the system (it needed a good clean anyway, 🤣).
Where did you find this info btw? I mean I'm not even getting anything on the display and it's stuck in some kind of infinite boot loop. If I then turn it off using the power button (pressing it down for 4 seconds) it will sometimes (after like 5 seconds or so?) power on again after which it will just get stuck again in the same boot loop.

There's no mention of a fix for this on the main BIOS page for the board.

LiR2032 and ML2032 are both rechargeable

Gigabyte forums. Came across it It a while ago, trying to troubleshoot my brother in law's pc. I've since then used this method on several "dead" GA boards with good results.

When it didn't I would re-flash the bios. POST loop means the board is trying to initialize something and failing. In the case of all gigabyte z77 boards exhibiting this behavior (any model) it's ram. I verified this with a pci diagnostic card. My x79 had dual bios, and instead of looping it would reboot, post and display "overclocking failed!" and restore cmos defaults

The P4P800-X/Deluxe/VM series has issues writing or reading from EEPROM using the stock winbond chips they come with and sometimes corrupt BIOS. Replacing the stock EEPROM with Amtel chips I got on ebay fixed my boards as they started dying one by one. They do make exceptional boards as well, but only later generations

So that's why I kept getting dead P4P800 boards left and right 🤣, now it makes sense.

I still don't get how you define 'high quality'. What are your objective criteria?

So you and the rest that claim, there is no difference.. [...]

I did not claim anything. That was my first post on that topic and I simply wanted to know how you define quality since you mention that constantly.

In my opinion you are mixing up several things but I'm not interested in disputing other people's world views if they don't affect me 😀

Any more specific hints on which chips these are/exactly where to find them Amtel chips perhaps ?

I thought Socket3 meant Atmel. I never heard of Amtel.

Me neither... 😆
Hence the need for some more info.

Amtel, winbond etc are chip makers.

I have not heard of Amtel making sockets.

Cheers,

Even Google thinks you mean Atmel when I google Amtel EEPROM 😀

I don't think anyone suggested they make sockets. Socket3 is the member we were replying to

Happy owner of a FX 5900 Ultra! 😁

Very nice addition for occasional use in an athlon xp multiboot system.

Got myself a set of cheapo speakers for testing purposes. It was said to be a backup and left mostly unused. The audio quality is serviceable at best, it'll be alright for the purpose. No discoloration, but judging by the smell the previous owners were chain smokers. I'd leave it on the balcony for the night if the weather wasn't rainy.

Looks like the 3 graphics cards are an ASUS 9800GT (maybe 8800GT), a Radeon 9550 (maybe 9600) and probably an X550. For 99p it's not a bad deal even if the only usable part is the cooler on the 9800GT.
