CPU Galaxy overclocked an AMD 133 Mhz 486 upgrade to 200 Mhz. And I remember seeing those Pentium Overdrive chips on the shelf in my local store back in '96. I was a a new parent and was there with my wife buying baby clothes. I remember picking up the box and wishing I could get one to upgrade my 486, and they were on sale for $249.00. But at the time I couldn't afford it. A year later I was able to upgrade my whole system to a new Pentium 233 MMX. A little over a year after that I was rocking a K6-2 400 Mhz. The tech was moving fast back then. Crazy thing is now that AMD is back in their groove, it's moving fast again! Competition is grand.

@@vswitchzero I wonder if anyone has managed a quad Socket 4 Overdrive? The Pentium Overdrive CPUs for Pentium Pro and 486 were forced out of Intel because of promises they made, tied to investments and other business stuff regulated by government. Intel was faced with a choice of producing *something* or paying big fines. They really didn't want to make those Overdrives, which is why the POD runs at the odd frequencies and the Socket 4 one doesn't run in quad. To use it on a quad P-Pro it can only be used to replace CPU 0 and 1, 2 and 3 have to be empty. Mattel got into the same make something or pay big fines deal with the computer addon for their Intellivision game console. After blowing tons of time and money on a computer for which the game ended up being a peripheral, they did a pivot, produced a POS addon that barely satisfied the SEC, sold a few of them then shut down Mattel Electronics.

Much like you said it was so much cheaper to go that route than to look into the POD despite the clear FPU benefit of the POD. Also, I seem to remember seeing a lot of results in magazines at the time that showed that on paper the Cyrix 5x86 should have been the clear winner in many cases, but in real world tests it usually didn't pan out that way. Those type of results seemed to have kept dogging Cyrix later on with the relative low FPU performance and heat issues of the M1 6x86 chips and lack of clock speed scaling of the M2 6x86 chips especially compared to the AMD K6-2/3 CPUs.

The AMD ADW version had a lower TDP than the ADZ version and it was 5 volt tolerant. I owned a few of them I ran at 4x40Mhz at 5V with no problems. How? By careful preparation of the heat sinks. Most 486 heat sinks were pretty arse, not at all flat on the bottom side. The solution was to clamp a flat file in my bench vise and run the heat sink over the file until it was flat. Then I glass bead blasted the rest of it to strip off the color and thick oxide layer from the anodizing. The bead blasting also left a satin finish which I figured slightly increased the surface area for better heat radiation and conduction to the air being blown over it. For applying thermal compound I used a fingertip to dab a thin layer over the whole top of the CPU. Press on the heat sink and anywhere it didn't transfer got a finger dab of compound. That got the absolute thinnest layer of compound with guaranteed 100% contact. Too much compound with poor coverage can drastically hinder heat transfer. If you don't want to have to clean a finger after doing this, wear a nitrile glove. I'd love to see someone do a thermal test on Socket 4 CPUs with a heat sink that's been filed flat on the bottom, then test again with it glass bead blasted all over, except of course the bottom. The Cyrix 5x86 would be an ideal tester for this. In my experience those run HOT. I once got a 2nd degree burn with a blister when I accidentally barely brushed the stock, green heat sink with the tip of a little finger. No fan on it, and that silly flat plate atop the fins to hinder convection. What was Cyrix thinking? A lot of motherboards couldn't set the correct signals to make the AMD chips run at 4x multiplier. There was an easy fix by jumpering from a Vcc pin to the pin which activated 4x. Fortunately the two pins were right at the edge with only one pin between. So I'd take a piece of one strand from some wire, bend it around the pin in the middle so it wasn't touching, then loop it around the Vcc and 4x pin. Then I'd take it off, tighten the loops a little and push it back on. The mod could be done by soldering wires to the bottom of the socket and installing a switch or 2 pin header for a jumper, but the "hotwire" method was pretty much invisible and removable. Running at 50Mhz FSB was out of reach on any PC I had then because I couldn't afford the eye watering prices of the higher speed DIP SRAM cache chips that would require. I had one MicronPC that was solid at 3x50 (might also have been good at 4x50) but only with L2 disabled. With no L2 it was way slower than at 4x40 or even 3x40. At 3x50 with L2 it would boot DOS then crash in a few seconds. I did have one POD system, a Packard Bell pizza box 486-25SX with a POD63. The board had a jumper to change FSB between 25 and 33 but the poor POD absolutely would not overclock to 83 Mhz. Buying a POD83 was not an option. I could buy most of the cost of a new-to-me Socket 7 board, CPU and RAM for the price of a POD83 so I suffered along with the POD63 until I saved up the $.

I built and rebuilt a lot of Am5x86 systems for friends and family in the late 90s, they were certainly the best of the common 486 upgrade CPUs! I almost never saw the Socket 3 PODs, though Socket 5 ones were more common. One of my tests for a system was, "under Windows 95, can I do other useful things and also leave Winamp running in the background?" On a DX4 that answer was often "not really" (depends a lot on the motherboard, cache/RAM, and hard disk performance), but most Am5x86 systems could handle it.

My first big PC upgrade was a Cyrix 5x86-100 and PCI motherboard back in late 1995. Was a great upgrade from my much slower Cyrix 486slc33 which was my first desktop PC (at least my first desktop PC which was all mine). A year later I upgraded to a Cyrix 6x86-P133+ and sold the Cyrix 5x86 and board to my dad to upgrade his PC, but sadly shortly after it failed. The chip had a green heatsink on it but no fan, I don't know if it was a temperature issue but the CPU just wasn't stable (wasn't overclocked either). Shortly afterwards my dad upgraded to an AMD Am5x86-P75 with a heatsink and fan and that was much more stable and worked well until he upgraded again a couple of years later. For budget upgrades they were great CPUs. Of course I'd have loved to have had a Pentium back in the day but they were just a tad too expensive, and the Cyrix CPUs were ideal for my needs (well, until Quake came out, but I was more of a Doom and Duke 3D player anyway). I'd be interested to see a comparison of Pentium class CPUs. I upgraded my Cyrix 6x86-P133+ to an IDT WinChip 200 in 1997, it was then where I got my first taste of virtualisation using a very early version of VMWare Workstation, I seem to remember it performed like a 386, but was still pretty cool to run a PC inside a PC :-D

I didnt win by a huge margin and It was only thanks to the mouse I was able to skillfully aim the singlebarrel shotgun and do damage from far away, it was like a sniper just with a lousey scope. I took home the prize of $200 gift certificate and chioce of any game in the shop. That being said the 486 dx chip we bought was relatively inexpensive like $60, consiering the system cost $5000 jus a few years earlier it wasnt a huge loss and learned my first lesson in computer upgrading.

Only 30 years and now we got 16 core monstrosities with clock speeds pushing 6ghz at the top tier, like the i9-14900k or R9 7950X3D. (I also can't help but to find it funny that those old AMD chips have prefixes of "AM5" and now they've created socket AM5... Full circle hehe...)

Sweet collection. I made do with a 486DX-120 on a VESA only board. Which isn't a bad deal in retrospect. The later PCI boards would penalize you almost for using 40mhz, they would declock the PCI bus to keep it from running over spec at 40mhz.

What Killed Cyrix was the fact it could not do CPU + FPU math simultaneously unlike Intel's or AMD CPU's, something that Quake used and (to a point) would make the system (maths wise) be like a dual core cpu. With Cyrix this would not work as INT math would not run simultaneously with Floating point math crushing the maximum performance available.

I was one of those few that ran my AMD 5x86-133 at 150 mhz and it was super stable. I used a Diamond Stealth 32 vlb card and just got lucky with the cache on board I guess. I ran it for 2-3 years before I finally upgraded. It became a backup machine once I built a pentium system so it stayed around longer than I would have expected. It ended once my then gf cousin shorted out the motherboard, but I still have the chip to this day. One of these days I'll get around to seeing if it will still boot.

I may have missed you mentioning it, but does your PCI bus actually run at 50MHz when the FSB is increased or is there a divider that keeps it at 33 and you had to adjust it? Your 160MHz 5x86 runs marginally quicker than mine overall, but it's good to see a direct comparison. Might be the RAM timings and such that make the difference, as you're pretty good at tweaking those. I would agree that the POD isn't worth it. Intel had to deliver it because they'd made such a fuss with their 'vacancy' ad slogan, but they definitely priced it to discourage buyers. OEMs *hated* upgrade chips if it meant users delayed upgrading their entire system for a couple of years. I still want one so I can put it in my 5V motherboard. 🙂

Thanks for your comment! Yes, it is indeed running at the full 50MHz. The Shuttle HOT-433 only has two settings, 1:1 and 1:1/2, unfortunately. It was either 50MHz PCI or 25MHz PCI at a 50MHz bus. Not many of my PCI cards could handle it.. all of the S3 cards I have would get really weird at that speed. Thankfully the Millennium II is totally happy and I have a newer Permedia 2 PCI card that is too.

Cyrix FPU is basically what killed Cyrix in their later chip too. What is interesting is that knowing this chip was released they could have benchmarked quake in-house to see the possible problems for their future gen too. For integer performance I think AM5 is beasting over Cyrix because all tests are highly optimized for 486 hardware - likely avoiding branches with unrolling and maybe not having enough headroom in pipelineing to compensate. That is basically gains of the PoD and Cyrix does not totally shine with software highly optimized for...486s and quake shines here, but Cyrixs slow FPU is burden there... What is also interesting is that 586s have also new instruction sets, so I guess you can use all new instructions with cyrix and Pod but not sure of the AM5 (maybe yes and emulated inside silicon). Thus for software development those might be good choice in case you only want to support new instruction sets with software you make, but not want to buy full systems for it yet. PS.: I had 40Mhz Cyrix 486 with a good motherbord and Vesa local bus card, then switched to pentium 1 MMX 200Mhz. But switched likely much later than 95 I think. Maybe like 97 or 98 and only because dad worked in IT. Before all that we had an Elon Enterprise 128 that we gave away to family and lost track of... so sad for that one haha

If I understand it correctly, Intel DX4 has some enhancements backported from the Pentium line, that's why it performs better if you compare it to Am486 DX4 with 16kB cache. Am486 is a clone of DX2 after all, with no such enhancements. The same applies to 133MHz version.

The Am5x86 was fastest Desktop 486 CPU released during the 486 era. AMD continued the line with the Elan line of CPUs. SiS/DM&P produced odd hybrid architecture CPUs in the early version of the Vortex86 CPU line which were neither Pentium nor Pentium II though they had MMX but also lacked some of the Pentium & Compare/Exchange instructions. The early ones were weird kind of super 486 DXs with fast CPU clocks (300MHz-1GHz) and MMX. Compatibility and real perf was poor though.

I never really saw thermal paste used on 386/486/pentium generation chips. Although seeing heatsinks attached with thermal glue or epoxy was pretty common. It wasn’t very critical as TDP was much lower compared to more modern chips. I want to say it wasn’t until the P3/K6 era that its use was widespread (especially with exposed die chips).

I really liked those Shuttle motherboards back in the day, Interesting they are still in business, but make all in one systems, and micro PCs, probably for industrial situations, cause they have kiosks as well. I guess everyone finds their niche! :D I think shuttle was my go to 486 motherboard, and built many PCs for family and friends. AMD was often my top choice too, they seemed to provide the best value and compatibility of the time. The Cyrix and Via worked well, but there were a few compatibility issues as I remember. AMD was usually way way cheaper than intel and about the same price as Cyrix. The local computer shop sold them at tray prices, and you got the chip in an anti-static foam square, opposed to retail box, so they were really cost effective. The local shop had trays and trays of AMD chips, he must have gotten a good price on them buying so many too.

Those overclock scores are something - my AM5x86 running at 160Mhz (40x4) can only get to 75.3 fps in 3DBench and about 45 in Doom with a Trio64 (barely edging out a Virge/DX), 90+ and 57 are incredible results. Is that UMC chipset so much more performing than the SiS496? (the fact I also get around 16.2 fps in Quake, which is not a world away from your 17, makes me think that yeah, the chipset is the big difference)

Thanks for your comment! I have noticed that benchmark scores can vary a lot on 486 platforms. Some of it must be due to the chipset, but wait state configuration and timings can make a big difference too. Some boards automatically implement PCI dividers when frequencies go above 33MHz. On this board, I can force it to stay 1:1 with the FSB. I've also noticed that some boards (I have a VIA based 486 PCI board) have really slow default PCI settings in the BIOS. I guess there were compatibility issues with really early PCI cards. On that board I could get huge boosts through various BIOS tweaks.

@@vswitchzero That is very interesting, I hadn't thought about the possibility of my board having PCI defaulting at 33Mhz. I now want to get one of these clock display cards. As for the BIOS, there isn't much I can change - the board is a relatively late one (LS-486e Rev.F), but it doesn't have many options beside the usual wait states - which do indeed make a massive difference, I get the 75.3 FPS in 3D Bench in the "most squeezed out" configuration, essentially one setting shy of crashing on the memory test.

I've never been able to run a PCI 486 board at 40mhz for very long without hard drive corruption. Maybe my bad luck but the IDE controllers just can't handle the full bus speed. I'm talking bad enough to trash the OS files requiring a reinstall bad. Good for benchmarking, but not real world use. At first I wouldn't believe it because 'everyone' runs the 5x86 at 160mhz, but it just kept happening. I suspect alot of people who had success were inadvertently running their PCI bus at 20mhz, as most boards automatically set a 1/2 divider for the PCI. That's why I like the POD. Uses in spec 33mhz bus, but is still very quick. The 5x86 at 150mhz (50x3) is also very good, but you usually have to run the PCI at 25mhz, like a Pentium 75. 50Mhz PCI gave me awesome benchies, but again dead Win95 install after less than a day. It even corrupted my Transport Tycoon save game :( The ultimate luxury is having a 486 PCI board that can run the PCI bus at a 2/3 divider. This means 33mhz for a 50mhz FSB, and 27mhz for a 40mhz FSB. Very workable, but not common. It's not just the 486 that does this either. I have an i815 Tualatin board that refuses to budge over 37.5mhz PCI without constantly getting scandisk runs at boot and corrupting my files randomly. This is the dirty secret that overclockers often don't like to mention ;)

Very interesting, thanks for sharing! I think I may just be very lucky with the systems I've used. The Shuttle HOT-433 4.0 seems to have a very tolerant IDE controller and seems quite stable at 40MHz. I haven't done any extensive use of the system at 50MHz, so I can't say for sure how it would handle it longer-term. I think I'd find out a lot more quickly if I installed Windows 95 on the system. A 2/3 divider would be great to have. This board only has 1:1/2 or 1:1, unfortunately. I can't say I've used PCI 486 systems much. Most of my experience has been with VLB/ISA based systems.
