 |
|
I have a Ceramic Intel w/MMX tech 233.
SL571
I cannot find any info on it. Is it a rare chip? I know that Fiber MMX chips started to come into play at that time so I suspect that not many of these Ceramics were made? See Photo-stream.
Any info would be helpful.
Thanks

Interesting. Out of curiosity why do you say that? I'm assuming that since it’s been hard to find any info on it that perhaps Intel did not make it? Or were these types of chips never manufactured?
I certainly did nothing to create a fake chip and the gentleman I got it from was a college professor who did computer repair/consulting many years ago. I got it (plus a bunch of other "vintage" computer stuff) for free so there was no financial gain on his part.
I guess I would be most curious to know why this chip would be faked? (other then perhaps a financial gain of sorts?)
I'm no CPU expert and I appreciate the expertise and opinions of this forum.
now I'm all confused  |

Always financial gain It likely started as a 166 or 200 and was remarked
They either sand them down and re-engrave, or paint over and remark.
Yours is rather obvious as the fonts are incorrect, and front and back specs do not match
The 486-Pentium era was the hey day of remarkers. It is one of the biggest reason Intel moved to locked multipliers and other methods to make such remarking harder

| Very interesting. Would certainly make sense. Buy a bunch of 166 chips and remark as 233 and resell for several hundred more dollars. I imagine those chips ran super hot and created all sorts of instability problems. Well one more to add to the refine pile... Unless anyone collects remarked chips? Heh. |

there are some people that collect fakes/remarks, but if no one wants & you are going to refine.. you can use fine sand paper on the die cap to find out what it was
Generally fakers only paint over die cap markings then remark.. so the original markings should be still there under the black paint.
Guessing probably 166MHz SL27K
