|
|
I bought a SK124 recently and I found it a bit weird on its print.
It seems the model area on the top side has been remarked?
and bottom side "SK124" print has different color compared with first two lines print above it.
Is this could be a fake? _________________ Want List

SK124 is fake in my opinion. Looks like polished top with flash will looks much worse. There were many P100 fakes because of sense to do it = overclocking 75/90 MHz versions.
And yes making separated thread for every chip wasn't good decision  _________________ Visit ABC CPU - Virtual CPU Museum. |

i emailed seller,he said :"I do not believe either to be fake, The SK124 probably had a sticker on the bottom side which when removed dulled some of the print."
According to my experience on chip collection , I don't think the sticker would affect the print.
Any opinion? _________________ Want List

The die markings at this period where applied at different times..
so colouring differences between die code/plant code & part number/sSpec are very common
stickers on Pentiums don't general affect print colouring but the stickers on IBM/Cyrix do as they use a different adhesive
Depending on the production date, I have a list to check for fakes
Genuine Pentiums can vary... so up to 3 fails on checklist are likely to be still genuine
3 to 5 items.. it goes in my need more info pile
above 5.. the Pentium is a definite fake
The SK124 by looking at only the pictures.... gets a 0 (zero) score _________________ There are 10 types of people in this world:
