M919 Fake Cache and Reproduction L2 COASt Modules

  • Recently I got this Quantex 486DX computer with a PC Chips/Alpina M919 v3.3B/F motherboard. Turns out it's infamous for having fraudulent Level 2 cache! A few companies were doing some shady crap back in the day with fake/dummy cache chips. Not only that, but it goes so far as to lie and say that the cache is actually working when it's not, and apparently there's even some kind of lockout where you can only use their proprietary 256K COASt module. Wow... Luckily, a modern reproduction of the M919 256K cache stick exists and I've got one. Let's try it out!
    Here's where I bought the new cache stick: www.ebay.com/i...
    And more info on the reproductions: www.vogons.org...

    FWIW I have the 3.2 version of the M919 (with the same reproduction 256k cache module and AMD DX4-100/16k write back cache) and the 3.4B/F (with original 256k cache module and Am5x86-133) and both are rock solid with 60ns EDO RAM. Both CPUs run at stock speeds with the memory timing in BIOS as fast as they'll allow which make them surprisingly quick (relatively, of course). With as much flack as these boards get they're surprisingly solid!

    They actually make dummy ICs that are used for things like testing manufacturing equipment or teaching people how to solder. They're like normal ICs but without the actual silicon chip inside, and are presumably made with the same industrial process. The fact that the manufacturer didn't even bother spending a few cents on a *good fake* feels like adding insult to injury.

    I was lucky enough to get a Dell 486 but ran across an issue where it would just power off randomly and then not power on at all until it wanted to. Took a solid week of troubleshooting but I was finally able to trace it back to a cracked solder joint on one of the power control chips on the motherboard. After reflowing the solder I was FINALLY able to get it working reliability. Now if I can just get a CD ROM to work I'll be all set. Unfortunately I think it's a proprietary IDE port on the Sound Blaster card so I have no clue how to find a CD drive/drivers for it. :(

These 486 motherboards were manufactured at the beginning of the "PC Chips lottery" when multiple brands were stamped onto only a few different motherboards. There was Shuttle, Amptron, PC Chips, and ECS mostly, but all of them (iirc) were just cheap computer hardware.

    This was INSANELY common back in the late 486 and early Pentium days. I have three different mobos with fake cache chips. ALL look like that with traces that just join the two chips. Sad part was, this was normally done on boards that were actually otherwise high end. My best and fastest 486 board with PCI and VLB also has fake cache. The fix was to just use a COAST module (all mine came second hand with one already). Most of these boards also used a graphical BIOS.

      Yeah. That's the great dichotomy of the fake cache plague. I gather that most of the fake cache boards were actually manufactured by PC Chips and rebranded by other companies(my boxed with manual fake cache board has NO manufacturer marks of any kind). And the M919s were actually fairly nice boards when done right, but PC Chips was ABSOLUTELY willing to do things wrong to meet a business customer's desired feature set and price point.
      "We want your M919 VIP board, because having VESA and PCI both is hot, but we want it cheaper. If we didn't want cheap, we'd be making a Pentium."

Where I live (Tasmania) you could not get the COAST module you are showing off, lord knows I tried at the time.

      The fact that the real upgrade is proprietary makes it look more like a scam if you ask me. They make the buyer think it already has L2 cache which makes them look better compared to similarly priced hardware, and for the customers that actually needed it they force them to buy their specific (and probably overpriced) upgrade when they find out they were mistaken. Taking the tin foil hat on, bricking the motherboard if you try use a generic L2 cache might have been intentional as well.

    These PCChips boards are so strange. Honestly, I don’t understand why they went through the effort of putting together a really solid board-decent chipset, decent VRM, and VLB/ISA/PCI compatibility-all to just add fake L2 cache. The M912 v1.7 is also somewhat similarly-afflicted, but what’s really weird is that not all of them have this issue. Some have fake “Write Back” DIP-28 modules soldered directly to the board, and others, like one I own, actually are equipped with DIP-28 sockets for cache chips! The best part is the shady chipsets, which claim to be UMC8498Fs, but some of which have a UMC sticker, rather than a silkscreen. I think PCCHips wasn’t the only company to pull this stuff, as I’ve got an MTech R407e, which was sold as having previously had 256kb of fake cache, whereby half of of the cache was real, half was fake, and the BIOS reported 256kb. Sure, I get that the manufacturer is saving money, but why? The board worked great with 256kb of real cache installed too-that’s the real kicker. As for the M919, it’s a real good board. I know CPUGalaxy had success with his in overclocking, and it’s unofficially capable of a 60MHz FSB. They’re fast, too, but the fake cache mars their reputation; it seems like they’d be heralded as really good boards if it weren’t for the shadiness that surrounded their marketing. One other thing: the PCI bus has an automatic divider such that-at 40MHz FSB-the PCI bus runs at 20MHz! As much as the M919 is legendary and infamous, it sure is one weird board. Don’t know if it helps, but I saw you found the manual and, for quick reference, Ultimate Hardware 2019 has a good jumper manual: www.win3x.org/uh19/motherboard/show/582. RedHill has some info on this board too, and it was apparently not well received by the shop, due in part to PCChips’ shady business practices: redhill.net.au/b/b-96.html.

    I remember reading about the fake L2 cache MB's. Part of the reason why PC Chips had such an awful reputation in the mid to late 90's. Even when they rebranded themselves as ECS later on the stigma partially remained.
    Also, adding L2 to a 486 system doesn't make a huge difference in most DOS based programs & games (with some exceptions of course) but it does make a noticeable difference in Windows, especially Windows 95. I had a 486 DX2 66Mhz based machine from 1992 that I had upgraded to an AMD 5x86 133Mhz CPU (running at 120Mhz due to MB issues) and adding 128KB of L2 to that machine via socketed chips on the board made a nice difference in Windows 95 back then. Hardly noticed a difference in DOS. I had the option of adding 512KB of L2 to the board but it would have cost much more than 4x the cost of 128KB and being a broke teenager at the time I couldn't afford it.

    I was told about this ‘fake cache’ situation with PC Chips mobos and found your video. Amazing! How that’s even possible really escapes me! I have a socket 7 motherboard with cache issues, my chips are also suspicious (can’t find any mention online and they’re labelled ‘PB CACHE’) but they intermittently get very hot so something’s happening inside. I’ll check the traces but they seem legit. Nice video!

    Huh, such a fascinating and oddly dumb thing - I only dealt with prebuilt PCs back when (mainly Compaqs, a few Dells) in 486, Pentium and compatibles times, so I didn't get to scratch the fun (albeit sometimes stupid) sides of components until the Socket A/370 era. Granted, prebuilts with their ginormous amount of proprietary bullcrap wasn't exactly always fun either.
    Nice video as always, Clint! An AudioDrive (ES1868F is such a lovely chipset) would be a "slight" upgrade for that awful Vibra16! ^^

Web browsers are a good test, too - Mozilla would run a fair bit smoother while using the very same DX/2-66 after swapping out a slow VLB board for one with roughly doubled main memory performance, and that's with L2 cache already in. I also found a lowly Pentium 133 to be surprisingly snappy if decked out with 512K of L2 cache + tag RAM on a GA-586HX even with just fast page DRAM in it (I had gotten a good deal on 128 megs of FPM at one point, and this was my NT4 machine as well).

    This PC is so similar to the first machine I built myself. Cyrix CPU, PC Chips "VIP" M919 mobo, Opti Viper sound card (although mine worked just fine). I also had a Trident VGA card (pulled from my old 386) and a Quantum Bigfoot hard drive for all the slows...
    I think an entire generation of tight-fisted PC builders ended up with a machine like this. It was inevitable in 1995 when you bought the cheapest of everything.
    Those motherboards could be really unstable as well... I went through a phase of being convinced that Cyrix/ST CPUs were flaky in Windows due to these things. Wrong culprit.

    Hey, Clint! That "Write Back Cache On" POST message most likely refers to the internal Cyrix 8 KB cache (which is, in fact, write-back). The guys at PC Chips probably thought that mentioning it on the POST screen would be a "clever" way of deceiving customers without technically 'lying'. :-)

The drive is a Toshiba SD-M1202.

Also its not keeping cmos cause looks like the jumper is missing on the 2 center pins where external battery goes

    Fascinating. This was genuinely useful. I have one of these boards, but without the fake cache and with the original COAST module. I bought it in the 90s and ran a standard 486 I think. I occasionally use it when I need real DOS for some old engineering software that I have. Currently I have an Intel DX4-100 along with 64MB EDO RAM on two modules, but I am honestly not sure that I have all of the CPU links set correctly. CPU voltage is set to 3.3V, but I shall have a play with the others to see if the cache performance is affected. The user manual was limited in detail and clarity of information. I need to find those benchmarking programs that you showed.

    My first video card oddly enough had the same memory chips that were on a 286 motherboard I was given. On the video card and the motherboard the chips were socketed, so I pulled the chips from the board and added it to the video card. It bumped the video up to a whole 1M. Used on a 486 DX2 66 system. Quickly upgraded to a Pentium 2, and an All in Wonder, with a sound blaster live platinum. Kinda made big jumps.

    This might very well be a newer version of the board I had back in the mid-late 90's, for the first PC ("It's ST" 486 DX2/50 with 4mb ram) I ever built myself. I'm fairly certain mine didn't have VESA slots (not 100% on that though, maybe it did and i'm not remembering) and that it had fake Write Back cache chips but through hole versions (which I didn't know were fake until quite a long time after i'd bought it)! I assume it has a rigged bios. I'd still like to find one just for the sake of it! I found a webpage/blog that some one made a while ago where they had a PcChips board with fake Write Back through hole chips, so they removed them and sliced them in half to find they were pretty much just solid plastic with chip legs and no core whatsoever, so they replaced them with proper cache ram chips and it actually worked fine and detected them (and in fact performed really well), so those ones at least had all the correct traces running to and from them!

    • @MrDuncl
      @MrDuncl 3 года назад +1
