Why your x800 pipe mod may have NO chance of working

[FSBuster]

Just read an interesting article in Computer Power User mag on the x800 (pg 44). It says that the x800 R420 core is manufactured with a scalable process, and they have the ability to disable a block of four pixel pipelines if they're defective, and still use the chip in an x800 pro config.

The chip has four independent blocks that each have four pixel pipelines (16 total). However, if there is a flaw with one of the blocks, it can be disabled such that the chip can work with the 3 functional blocks (12 total). This allows ATI to use the 12 working piplines in an x800 pro instead of trashing it. The article goes on to say that they may even release a version with only 2 working blocks (8 pipes) in the future. The article also says that they have been achieving higher than expected yields of 16 pixel pipleine chips. This seems supported by the number of successful x800 pro pipe mods.

Sounds a lot like what Intel has done with the Celeron, ie when part of the cache is defective, they fuse it out and sell it with the smaller cache size.

So if you try to enable the xtra four pipes with the x800 pipe mod and it doesn't work, it may have had no chance from the start.

That is why youd be better of taking a x800 pro VIVO, cause those one are XT disguised :D

The 1.6 memory is the best proof of it!

w00t mine was!

You go Mr.G!

[Mr.Guvernment]

You go Mr.G!

lol

you go girlfriend!

what has me is i play joint operation typhoon risingh - and @ 1600 x 1200 and everything max with NO aa or AF - it is choppy!! - i am hoping it is just bad coding on novas part as usual.

i played battlefield 1942 secret weapons with all things on MAX - again no aa or af yet - and it ran fine - also -didnt really like the game play of BF 1942 - i found call of duty to be better

ANYWAYS hopefully by mon / tues i will have my case / abit Ai& and then i can set up this 2.6C and such adn then let the bench marking begin!

THEN i am now thinking on my next pay check - for some unknown reason - go grab a 6800GT if i can find one of the cheap ones :d then have 2 1337 machines..lol and do my own dam tests! :D

GF??? huh?

What no "Why you should buy a GT" or "Why you shouldnt be such a scrooge and just buy a f-in XT" thread?

....lol

Seriously. Softmods were always a crap shoot. Glad it helped alot of pplz, but for the most part it dosnt work. Sometimes $100 is worth avioding the hassle.

Be careful Mr.Guvernment, you may like the GT better. Its a fantastic card....despite what "some" people say about it :rolleyes:
