Intel Pentium Bug

[hul2000]

Pentium FDIV bug

The Pentium FDIV bug was a bug in Intel's original Pentium floating point unit. Certain floating point division operations performed with these processors would produce incorrect results. According to Intel, there were a few missing entries in the lookup table used by the divide operation algorithm.

The presence of the bug can be checked manually by performing the following calculation in nearly any application, including the Windows calculator:

4195835.0/3145727.0 = 1.333 820 449 136 241 000 (Correct value)
4195835.0/3145727.0 = 1.333 739 068 902 037 589 (Flawed Pentium)

ela... he he mama AMD....;)

[rsanda]

there r lots of these kind of mistakes
cause computer calculate these from 2base no.
1-0.99999999999
will also show a wrong answer

Intel Core2Duo also have huge bugs(Microsoft also release patch file for system bios to correct sum of them)

Critical update for Intel Core CPUs is out (http://www.theinquirer.net/default.aspx?article=40567)

Eth ithin Mr. Linus kiyanne ewa echchara gaanak nae kiyala.

However, Linux founder Linus Torvalds posted a message on the RWT Web site noting the bugs were "totally insignificant".

Weird thing is that it says "This update does not apply to your system".
Maybe that patch is included in the Reliability and Performance update (beta) that I installed, and is already present in my Vista installation. :)

I don't think so. It is coming through Windows Update and it is only 40 odd MB in size. (see first news item of http://www.thehotfix.net/)

Maybe what you are referring to is Windows Vista Service Pack 1 Hotfix Preview shown here: http://vistasp1.net/

P.S.
According to the 3rd news item at http://www.thehotfix.net/, it seems what was leaked as performance & reliability pack and compatibility & reliability pack are what will be available in windows update.

Almost all the processors contain certain bugs which are covered by software. It is typical that such errors exists as they are human made. Don't have to worry about bugs much because they can be patched by software safely with out any problem. Only what matters is the performace and the power consumption

Unpatchable bugs are the concern here.

:yes: :yes: :yes: :yes:

Buddy virtually there is nothing called unpatchable bugs. Because there is a solution for any problem in processors using software. If such a bug exist the people who mafacture it will detect it. There was a floating point bug in Pentium 2 also. So don't worry about processor bugs. Just keep your systems up to date

[zCexVe]

There are errors in every CPU.Even in core 2 duo white paper it has listed 120 errors.They are not very significant like the one that intel once had in past which actually affected calculating.

I know that ....last june Microsoft and Intel jointly release patch for Core2Duos..But they didn't say any word about why they release and what's the problem is:angry:
