Hi there,
yesterday a friend of mine gave me an old computer that he had at home, he contacted me cause he would threw on the garbage.

Obviously I stopped him from making this big mistake, and so he gave it to me.

Nice surprise for me when I opened it! A Super 7 platform was waiting for me! WOW!

And on the bundle it was a nice DIN keyboard and a serial Dexxa mouse with three buttons! NICE!

And last but not least, the monitor! A CRT that I owned about twenty years ago, a great Viewsonic 14" CRT model 6E. WOW, IMPRESSIVE!

So I tried to power on and with my big surprise all worked from the first second, wow. Hard disk loaded Windows 98, all fine. I had now words, I llllllove to see these systems working after years and years. Obviously the battery I had to replace to, cause the 2032 it was completely died.

I added some more RAM (this board has PC100 RAM, three slots) because only 64MB of RAM wasn't so good for me. So I add a 128MB module and a 64MB module, to obtain regularly 256MB of PC100 RAM. Nice.
The CPU is an AMD K6-2 300MHZ, I think a good processors. I put a bigger heatsink on it, with thermal paste re-applied, so tomorrow I will begin with the overclock.
For the motherboard I find some difficulties to find the exacty model, but reading here and somewhere I found that I have a Chaintech 5agm2-d150. I found the manual for the 5AGM model but mine was a little bit different for the jumper settings. No one have the d150 version manual?
For the video card there is a nice Matrox G200 on the slot AGP. Working flawlessy.
Audio card I have a Sound Blaster 16, the big version Ct2910. True OPL3. fabulous. Anyway I think it has some problems, cause If I play a sound from Windows it can plays only about one second of the sound then interrupt. I don't know why, anyway tomorrow I will format and reinstall all, perhaps this computer simply need a refresh.
And then the overclock!!!
A nice floppy disc, a slot-in CD ROM driver completed the "opera".

So, what do you think about this system that I found in a lucky-way???

I put some photos here, so you can see and be happy about that!

Be careful with that, as your system might not be able to cache all that RAM. Using more RAM than can be cached may result in lower performance. Generally, it's safest to stick to 128 MB or below, unless you have a K6-2+ or a K6-3+ CPU.

Very nice build otherwise.

Thanks a lot for the advice. So it's better to switch to TWO modules of 64MB and a total amount of 128MB?

I think I will do that, so I think that in Windows 98SE 128MB is more than enough, isn't it?

Yes, 2 x 64MB will be fine. Note that dual channel wasn't a thing back then, so don't expect a performance boost from using two sticks.

Generally speaking, 128MB will be fine for a (Super) Socket 7 build. However, some late-era Win9x games such as Deus Ex may benefit from more RAM and definitively need a faster CPU. Those games are best played on a different, more powerful platform though.

To my surprise, the 5AGM2 only has 512K level 2 cache so 128 MB is the limit without moving to a K6-3 or one of the plus CPUs. https://www.anandtech.com/show/140

Very nice! The only thing I would improve upon us maybe the CPU.

I'm building a similar system, the hardest part is to find a crt and a case to be honest mostly because if complicated/expensive shipping. I'm envious!

Oh yes, I saw that this motherboard with the 512kb of cache has the limit of 128MB of RAM. I have 128MB in two modules, and I know, no dualchannel here, the dualchannel begins with 754 sockets and over...

Ehehehe thanks for all comments, yes this CRT is so nice, but I have a better one, always from Viewsonic, the G90f+ capable of 1600x1200 resolution in a 18" size area. Capable of 100hz too. Sometimes I power on that monitor, I love it.

So at the end I will try to find a k6-2 550mhz, I just find one, tomorrow I will write to the owner and see how much does he ask for.

Anyway, I have another DOS system with a K6-2+ that runs at 450MHZ, with cache on it. I love that system.

This one is just to make some various test, I am installing Windows 98SE now.

PS: interesting to see that the CPU doesn't take 350mhz of overclock, even if I overvolt to 2,4v. Unfortunate CPU I think. Strange.

I attach other photos for you all!

Don't discount Freegle in your hunt for a CRT. I put an ad on there recently and picked up a mint 17" Samsung 753S the day after! A lot of people don't realise retro is cool again and have stuff just lying around.

Modern PC: i7-9700KF, 16GB memory, RTX 3060. Proper PC: Pentium 200 MMX, 128MB EDO memory, GeForce2 MX(200).

That's a nice system! Especially since it was just given to you 😀

Ehehehe exactly!!!

And this is my CRT that I love so much. Viewsonic G90f+.

But when I rais on resolution the image become less sharp unfortunately 🙁 I can stay at 1024x768 at 100hz, or 1280x1024 at 85hz, little less sharp.
