I have got PCI G200 for cheap. As soon as I have finished current tests, I try to make benchmarks.

Be sure to use a fan; these chips get very hot!

Yes, someone here did. Don't ask me who. It is up to him/her to reveal him/herself. What matters to me is that a [properly] scanned manual is coming my way.

All 133 MHz parts don't do branch prediction in Windows reliably; DOS is OK though. To get a 133 MHz part with branch prediction work in Windows, you will need to find an S1R3 100 MHz or 120 MHz part which can be overclocked to 133 MHz on a motherboard that supports the 66 MHz FSB.

Interesting thread. I have a Lucky Star 5VP3 socket 7 board that will run at 8, 20 and 40 MHz unofficially. I discovered 8MHz accidentally when trying to get a K6-2 to run at 6x66MHz. It's stable at all these speeds, but at 8MHz multiplier selection is disabled, the board will always force 1x regardless of multiplier jumper settings. I believe the 8MHz setting is a debug feature (please correct me if I'm wrong). Don't know about 20 and 40MHz.

I really would be curious to know just how the MII-433 @ 300 MHz compares up to the Pentiums. One day I'll get around to the ultimate socket 7 comparison. My gut feeling is that it is somewhere between a P233MMX and a P266MMX, perhaps even a slow slot1 celeron.

My 2.2v Mii-433 overclocks to a real 400mhz at that speed it does move fairly well but never benched anything 3D to see.

I believe someone did compare an overclocked PR433 vrs a celery 300a and came up with a few interesting results .

If Cyrix had sold real 400mhz parts in 1998ish they might have survived

Not sure if you are aware, but that question is almost a decade old. This question has been answered in the Ultimate 686 Benchmark Comparison. While I have an MII-433GP, I don't think I'd want to run extensive benchmarks at 400 MHz on it. I ran the MII-400 up to 350 MHz and extracted results for 400 MHz. The response vs. freq. was linear.

More power to 'em. At least users on this forum are unlikely to try packing them full of play-dough before learning the limits of LN2 cooling.

The Evergreen is in good hands. This user isn't the type to do something stupid like liquid nitrogen cooling to see if 150 or 160 MHz on a Cyrix 5x86 is sustainable.

Hey. That's what I would do! 😀

There are some QFP IBM 5x86c chips that will suffice then. I had one doing pretty well in DOS at 150 MHz with just a heatsink/fan... until I overdid it and it stopped working. I bet some liquid nitrogen cooling, or even a reliable peltier, could have yielded Windows operation.

Yes, obvious fake. Marking won't go so easy from a genuine CPU and there's slight difference in ceramic color.

people will go pretty far to fake

If it's relatively popular and sought after and can be easily faked - it would be faked without a doubt.

Hi
So I have bought AMD X5 160 and this happened..

Nice collector's item - I have a 486DX100WB and it's also fake but does work as label'd so not much was lost. Do you have a picture before the font was "removed".
