Sempron 2800+ ABIT AN7 for budget 'organ transplant'?
Hi, some background. I've never changed a mobo, just cards, RAM, HDs… I
need a new HD, but my mobo is so old: SDRAM, Duron, ATA 66, pre-137GB BIOS, & probable incompatibilities if I mix new with old. This led me to think that a new "Combo CPU + Mother board" from Fry's looks the best deal. Also, the ~160 GB ATA133 HD looks best deal (SATA still possible in future with most mobos). And, PC3200 or 2700. Fry's lowest priced combo is $60 for Sempron 2400+ ECS K7VTA3 Version 8.0c. But Usenet posts warn me off ECS or that board. So, REJECT. :-) Next good deal is Sempron 2800+ ABIT AN7 nForce2 Ultra 400 Socket A 266/333/400 MHz FSB $90-100. Jul 2004 Usenet posts.. implied AN7 was too new. But, I figure now, Sep 04, AN7 is 'mature'. Any comments, cautions? Do I have to be anymore paranoid about grounding than I do when changing RAM? (I stay put when messing with the innards, but don't have any ground strap for wrist or bodypart, though I could rig wire out window to house's ground rod) It's just a basic home use computer. Net, word processing, some basic still image work. Port/connections used are only Ethernet, USB, Parallel. |

It is cheaper than the Sempron has at least equal performance and MUCH better overclockability. -- *****Replace 'NOSPAM' with 'btinternet' in the reply address***** |

Its not necessary that anything is earth grounded. It is only
necessary to prevent any sparks to the mobo and such. By sparks I mean the type you get when touching a wall switch in the winter. FYI, it takes about a 3,000+ volt spark for you to even feel it on your skin. Smaller 2,000 volt sparks can damage components without you realizing it. The method I use is to *first* touch and hold the side of the case (exposed metal) with one hand while working with the other hand. In this way the spark doesn't reach the components. When I need both hands then I lay one arm against the side of the case while working. A spark between you and the case is not a problem. A spark between you and the mobo or chip is to be avoided at all costs.

4ax.com: Its not necessary that anything is earth grounded. It is only necessary to prevent any sparks to the mobo and such. erk, right. i forgot. strap goes to teh *frame's* ground going to house ground is especially useless since i'd have unplugged teh case from the house's ground, so teh computer's ground wouln'dt be tied to house ground anymore.

Smaller 2,000 volt sparks can damage components without you realizing it. yeah, think i've read it's the really low current (with hi volts)... we can't feel those.

Forrest i touch unpainted metal on box, often, and avoid moving around ------- Motherboard Help By HAL web site: http://home.comcast.net/~mobo.help/ hmm... i looked at teh toms hardware PS link.. my PS is sparkle 300w that replaced a 250w cheapo that burnt.. (cheapo mfr PS came in the local shop's computer that i bought) I tend to do little else while burning CDs, so i guess i havn'et overloaded the 300w. (btw, the 250w burnt BEFORE i put in the cdrw ) |

ocing?
I'm a noob's noob :_) I'M not planning to oc, especially since the atmosphere gets hot around where I live. and I've read that Oc-ers resort to use cooling systems to allow higher oc. But i'm trying to 'K.I.S.S' oc-ing is interesting, tho. kind of like race-tested auto design or like street nitro? http://www.carcraft.com/techarticles/116_9509_blow/ ----------- Side note: I see most Usenet posts in the last year about nForce2 Ultra involve linux.kernel ... Side note --- outpost http://shop1.outpost.com/search?sear...page=0&sqxts=1 &order_by=s00d&query_string=++Abit++&minprice=&max price=100&x=1&y=7 info is better than Abit's! http://www.abit-usa.com/products/mb/...es=1&model=158 |

"BigBadger" in
: The AN7 is ok but a far better CPU would be a Athlon XP2500+. It is cheaper than the Sempron has at least equal performance and MUCH better overclockability. I'm glad to read your suggestion. I'd looked at http://www.anandtech.com/linux/showdoc.aspx?i=2170 benchmark tests of a Sempron, an XP and two AMD 64s. most of the tests that seemed critical to my uses showed the semp usually as good as the xp (and about as good as the 64's). But now I see they compared a slow Xp2200 to the socket 754 Sempron 3100. And http://hardware.mcse.ms/message50395.html "And the Sempron for Socket A 2800+ is actually a tbred B core running slower (12x166) than the XP 2600+ tbred (12.5x166)." aha... of course CPUs can't be tested without involving effects of OS, chosen benchmarks, chipsets, boards, etc. also, mine is a budget machine, I want to keep costs low. Because there are zillions of options that change everyday, i have to begin my research with total costs of locally available bits. I could call local independent shops tomorrow, to see what AN7 + an Athlon XP2500+ (or other cpu+mobo) would cost |
