I have never seen a Radeon 7200 with default 200mhz core and 200mhz memory?? Maybe a weird proto sample? It does have T5 memory though.

cool. send a photo of the card? 😜 does it have the "new" geforce256 style heatsink or the slim one?

It looks normal, for all intensive purposes. Maybe someone modded the bios?

And to ease a bit of the RDRAM failure, ordered these three marvels.

- Pentium MMX 200 Ceramic
- some sort of Morgan Duron, judging by the core
- Pluto core, Slot A Athlon 700MHz (with dual fans, woo)

Direct screenshots from the seller, I wasn't up to cropping 'em.

Might get back into the slot A business, but I need a mobo. The last two I had are now gone -7KXA went to Robert B and the M7MKA was unfortunately unfixable, as far as it concerns.

No why. I think Radeons/Rages always matched the respective memories. For example I've seen 8500 and 9100 with the strangest configurations like 250/275, 275/250, 300/250 (this is weird, red pcb!), 250/200. I think you have found a rare 7200 or one of the final super binned DDRs.

Just opened it up during my lunch break. Looks like the mobo is an MSI MS-7184 v1.x.

The machine also has a Bestec PSU, so from doing some searching looks like I may want to replace that before trying to power it on.

If I had checked back on this thread two days ago and seen your previous post, I could have told you what motherboard would be in there before you opened the box. 😉 (Alas, my internet service was down.)

Don't fret about the Bestec PSU, just check which model it is. The only model that was known to be very problematic was the ATX-250-12E - often nicknamed "The Motherboard Killer", and for a reason (the 5VSB would overshoot to over 10V and usually kill the SIO and/or Southbridge on many boards.)
Now, if you have any of these: ATX-250-12Z, ATX-300-12E, or ATX-300-12Z, do not worry - these are actually pretty good PSUs. Of course, like many OEMs from that era, they might be due for a recap now. Bestec liked to use CapXon and Jamicon caps a lot, and those rarely lasted too long. Depending on which model you have and if they used the crappy tan glue that goes conductive, you might either have a PSU that is very easy to recap, or one that would be a bit of a nuisance. I've personally worked on all of the PSUs above (except for the problematic 250-12E - that one is pending as I just got it recently.) All in all, worth a recap. They make decent low-end PSUs for a modern build and also OK PSUs for a retro build that needs a strong-ish 5V rail (single Athlon /XP will be fine.)

As for the MSI MS-7184 motherboard, I have two of these. One is a Compaq OEM and the other was either a Gateway or an eMachines, IIRC. The Compaq needed a recap due to Chemicon KZG caps near the CPU VRM. The Gateway (or eMachines??) one is still OK, though it does have Teapo SM caps littered everywhere on the motherboard, and those are known to go bad over time and give trouble. With that said, it seems to be a lottery as to what caps one will get on these boards. The Teapo SM caps should be replaced for long-term reliability. The CPU VRM caps may or may not need replacing. My Gateway board, for example, has Rubycon MBZ caps, which aren't problematic at all. Either way, have a look at what caps are on your board when you get a chance. And if you need a recap, I believe my post on badcaps forum should still be there... actually, here it is, found it for you. 😉

This is not T12 tips and what T12 looks like are long tips shaped in a round bar, is changed by pulling out and pushing different tip into handle with a snap. This is small tips that you change by unscrewing the base nut, not best.

Agreed.
That's a Hakko 900M series style tips.
While the real Hakko ones (and the very good clones) can be pretty decent, the cheapo ones are terrible, IME. I have an early KADA 852D+ station (hot air + soldering iron) that uses these tips, and the ones that came with the station are complete garbage. Supposedly the station can deliver 40 Watts of heat (and it does!), but even the fat tips struggle with melting anything on a multi-layer PC motherboard. I can still solder with it, but it's a nuisance.

A real T12 (even the cheapo clones) is absolutely classes above the 900M design. Have a very early Circuit Specialists CSI 2900 (Aoyue OEM rebrand), and with a bevel 5.2 mm tip, I've soldered short pieces of copper pipes with it. No, the station wasn't happy and kept cranking full power into the tip for almost a minute before the solder started melting on the pips... but it got the job done. Now that's POWAH! 😁

I don't power on old PSUs without opening them up first. There is a very real possibility that the capacitors have failed and are leaking, even without ever having been used. I would also put it on a PSU tester before every attaching it to a motherboard.

PSUs are not the kind of vintage component that you want to mess around with. It's all fun and games until it takes out your whole system.

Several searches seem to match the tips for my soldering pencil to Gordak, of all things.

I usually prepare myself with screwdrivers and a 60-75W incandescent lightbulb if I have to work with PSUs, like replacing main switchers or main transformers.

Won this KR7A on the bay with a bit of a peculiar issue. It won't POST if there isn't a PCI card in the slot. Photo is from when I got the offer message 🤣.

file.php?mode=view&id=200873

Also one of our local town "scrappers" gifted me these. Two A7N8X, a 7N400, a Medion2000, a 775i65PE and a whole machine. Lots of cleaning ahead and one A7N8X has no socket...

That's for sure. I wonder if it ian't rotten caps causing issues on the slots' power delivery? It's almost 98% full of El' Cheapo Teapo (tm) caps.

Dunno.
If they're leaking I'd pull them, wash the board, and replace.
If they're not leaking... Wash it first and see if it changes. Then replace if it doesn't/you want to

Teapos love to fail with no signs. I'm well accustomed with them from MSI during the 2002-03 era.

Thanks for all the great info! The PSU is actually an ATX-300-12E RevD so it sounds like I might be ok on that front. I don't see any obvious signs of cap leakage, but maybe this could be a practice board to get my desoldering and soldering back up to snuff before I take to doing some of that work on my sentimental retro consoles.

Been long time last time bought any retro hardware.

810MB IBM notebook hard drive. If good, using it on Compaq Contura 3/25 as 500MB. Contura was bought eariler on 1 month past.

387SL math coprocessor.

two Compaq 486 motherboards both uses VLSI 481 and 483 chipsets and planning to use open source cache module for these.

Cheers,

Great Northern aka Canada.

I have a 486 Contura, hard to find stuff for due to google continually polluting the results with stuff for the contura aero models. Anyway, being a Compaq, you need the setup disk of course to make a setup partition, no CMOS setup in ROM. Also it is a real bugger about HDD types, I have been trying everything to avoid using an overlay on mine, but I think that's what is gonna happen at some point due to it just being a general pain the ass to get along with with non-original drive types.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Yea windows identified it as a Radeon 9100 , and it had an oem sticker on that back that read 9100 PCI. 😀

Yes, that's correct,

I had Compaq LTE 386s/20 as portable computer for college, yes I know about these disk needed to set up the CMOS settings. I do now have compaq computers so proceedure is famillar to me.

Compaq allows me to be selective about hard drive type and other settings, along with another option is automatic detection.

Creative/Msi TI4600. 30 eur. Artifacting most of the times.
Sometimes starts without artifacts, then crashes and reboots.
Can load windows despite the artifacts, but crashes pretty quickly.
Has an Abit Siluro bios for some reason, but it's clearly a MSI. Could be the reason it doesn't work.
I have no idea what fix I should attempt if flashing the original bios wont work!
