    Question which cpu?

    We am shopping for a CPU. I am a believer in buying 12 to 18 month old proven technology. Since it is usually 1/2 to 1/3 the price a year later and still can handle most of the latest software and games and has tons of literature, forum and tech guides.

    We are not well versed in all the aspects of overclocking. I have read for over 50 hours online about amd and overclocking. How do you know what processor is locked? Is there a serial number guide that shows better stepping in certain serial numbers? We really want to know the difference between a N82E16819103391 and N82E16819103390. And what does aqxdal/axda latest stepping mean?

    We are torn between 3 CPU's xp 3000 mobile 266 bus $135, a xp 3000 400 mb bus $141 and a 3200 400mb bus $185.

    Which one is best?

    We know everyones amd 64 crazy now, but i may build one of those in a year or so

    The Mobile sounds great from all of the forums i have read. I just have a hard time believng it is so easy to change the FSB to 400 and stepping the speed up. There has to be a catch somewhere.

    We know people say 2400 and 2500 and 2600 etc overclock to 3200 speeds. But hey! There are a lot more more transistors in the later cpu's, that has got to be worth something in performance.

    We know this is old info, but any info would be greatly appreciated. Please reply

    Thanks!

    You just cannot beat an Abit NF7S, 2600 mobile Barton, and some good memory, and yes it is just that easy to get 3200 -3600 speeds with some good cooling.

    Re: which cpu?

    so the 210 bus in ur 2600 mobile will take advantage of the 400 fsb on the ram? you do not need to buy a 400fsb cpu?

    Re: which cpu?

    A stock XP3200+ 400fsb runs at 11x200 = 2200mhz. You multiply 200 by 2 because of double data rate (DDR) and that's the 400mhz fsb. Golfer's mobile 2500 is running at 11x210 = 2310mhz. 210 x 2 = 420mhz fsb.....he is outperforming a 3200+ 400fsb processor. I run my mobile 2600 at 12x200 - 2400mhz with 400 fsb.

    All stock desktop XP3200's and 3000's run at 1.65volts. The mobile 2500 and 2600 run at 1.45 stock volts. The mobiles were designed to run in laptops with batteries so they need to be able to power up and down as needed to save the battery (so they all have unlocked multipliers and fsb). There is no room for big cooling fans in a laptop so they need to be able to handle more heat than a desktop - mobiles have a higher heat rating than desktops.

    The different steppings sometimes give better overclocking results than others. In my experience you are pretty much going to get great performance out of any of them regardless of stepping. Mobiles are the cream of the crop - the best of the socket A processors and they are much much cheaper than the desktop 3000 and 3200.

    I hope this helps you understand a little better. I would personally recommend getting a mobile 2600.

    Re: which cpu?

    FYI, the locked multipliers appeared in chips made by AMD from
    week 38 of 2003 and later. The date code can be found on the
    2nd line of digits on the cpu sticker. Example: AIUBA 0248ZPWA
    The 0248 is the date code; 48th week of 2002. Any chips with
    a code of 0338 will be multiplier locked.
    I 2nd SlyfoxG21; a mobile chip is the way to go.

    Re: which cpu?

    Ok! Sounds good to me. One little problem. I kinda jumped the gun when I bought my MOBO. I have read reviews that the nf7-S2G does not have a multiplier, I believe it does have FSB abilities. Am I correct in this assumption?

    If I get the mobile, will I be able to set it up to run 2.2+ and 400 fsb?

    Oh and I found OEM 3200+ at pricewatch for around $135 bucks from several vendors. I think the 64 us driving this old cpu price down. So a good 2600+ mobile is around $96. What u think?

    thank you for the replies! Keep 'em coming!

    The only Abit nf2 board worth buying would be NF7-S2. Unless you're not overclocking or in favor of other brands.

    you mean the NF7-S rev 2.0 not the NF7-S2, correct?
