Also will be good to see 286 with 40 or 50 Mhz with ATX mainboard with 8 Mb RAM, and Slot A Athlon with 1,4 or 1,6 Ghz with mainboard with SATA and DDR1 slots.

I'd prefer if they did some new motherboards + CPU limited edition bundles :) 386DX for sure, 486DX2 or DX4 would also be cool. That would be nice too, Like that new commodore 64 motherboard that you can replace the old one, and has some plus on it. I would like a super socket 7 that could support …

486dx plus an ATX mobo to go with it. The CPU has to be able to run from 25 to 130mhz using a single jumper and the mobo has to have button cell battery, ps2 mouse/keyboard and have PCI, ISA and VL-Bus slots. 72-pin memory? Shure, why not...

How's about a Socket 3 ~266MHz 45nm 486 core with 2MB of L2 cache and SSE3 bolted on? That would be fun to play with. Or how about an entire Core M SoC (system on a cartridge) designed for Slot 1 boards? The cartridge would house the CPU, any necessary VRM, and memory/bus translation logic to enable …

I want a 3-core CPU that plugs into any old cheap P4 mobo. 1 core of x86_64. 1 core of PowerPC G5. 1 core of ARM. Runs everything. ...Actually make it 2 cores of each.

A 500 MHz socket-3-compatible chip, bonus points if it's based on the Cyrix 5x86. :) To be honest in this day and age it's a goal probably achievable even by an advanced hobbyist. Using FPGAs and cleverly written HDL. I've been toying with the idea for a while. One major obstacle is that none of …

Revamped dual core socket 462 chip featuring all the P4 6-series instruction sets and features, clocked at 4ghz (on todays 28nm process it would be feasible) and 2mb l2 cache per core. With a new chipset to go along with it! IDE, floppy, all the legacy stuff of course. Plus Tri- channel DDR400 maybe …

I have modified SetMul to tinker with the multiplier options which are mentioned in the 5x86 Datasheet. The good news is that one can toggle between the bootup multiplier and 1.0x anytime, but seemingly that is about all it can do. It won't do any switching between 2.0x, 3.0x or 4.0x. There is no …

I have confirmed that SETMUL correctly sets the multiplier, in any order, between 1x, 2x, and 4x on Cyrix 4x-capable CPUs. I have used CHKCPU to confirm the internal CPU speed. Note that CHKCPU incorrectly displays the multiplier and FSB after using SETMUL or the Evergreen utility to change the …

Vetz? you mean me right? Thanks for checking. Glad it can toggle three multipliers on that CPU. Though I notice 3x mode was not listed in your post. Current Multiplier readout is not working: despite reading the registers stated in the 5x86 datasheet. Since the hardware is not communicating the …

gerwin, yes I was refering to you. Don't know how the Vetz got in there - I was probably viewing multiple threads. 3x was deliberatly not listed in my post. A 4x-capable Cyrix 5x86 chip, when booted in 4x mode, can only switch between 1x, 2x, and 4x, not 3x. A 4x- or 3x-capable Cyrix 5x86 chip when …

Is the improper value repeatable and unique for 1x, 2x, 3x, and 4x? If so, can use these static improper values as a calibration means to display the proper multiplier values? IIRC the received value is always the same. Maybe there is another means of getting that info? Though I rather not write …

How do I set HLF_CLK in SETMUL? Would it be, Copy code to clipboard 1 setmul 0.5 ? Also, have you thought about adding the Cyrix MediaGX to Setmul? There's quite a bit of documentation on th at chip.

No, Use "HSE" for half-speed enable, "HSD" to disable. SetMul lists these commands when you run it without parameters, or by passing "/?". Will check the MediaGX docs. Unfortunately I don't have such hardware myself.

Athlon XP-M can be set from 3x to 24x and FSB down to 50 MHz, so 150 MHz(which should be around a p200 in performance) to 2.6-2.8 GHz avg OC(almost a64 4000+ equivalent), by year that covers from 96' to 04' and software settable: http://fab51.com/cpu/barton/athlon-e24.html At 150 Mhz I wonder what …

Sounds cool in theory. I never had an unlocked Athlon XP. But I did notice that on an Athlon XP with L1 cache disabled: SB Live! PCI soundblaster emulation will malfunction (stuttering sound). So only boards with ISA slots are suitable for DOS gaming, which are only found on the earliest Athlon …

Looks like 100 MHz would be possible, or at least 107.73.
