Upgrading my PIII to a... PIII

My current PIII-667 system runs on a ASUSTeK CUV4X REV 1.xx motherboard. I'm looking to upgrade my CPU if I can pick up a good used one somewhere. Would anyone happen to know what's the maximum speed CPU an old board like this can handle?

(I'm assuming I'm limited to upgrading to another PIII and not a P4.)

My board, by the way, runs great, so I'm not interested in moving to a P4-compatible board at this time.

Thanks.

  1. You can put any coppermine PIII up to 1GHz, if you want to put a Tualatin you need to put a voltage adapter, then you can get to 1.26GHz.

  2. Not a voltage adapter, just an adapter that disables the Tualatin's shutoff circuit.

  3. You can run a P3 1.4GHz Tualatin on your board with a Lin-Lin adapter ($8 at Compgeeks), but if you really want a great upgrade for a reasonable price consider the Tualatin Celeron 1100@1466MHz (an easy overclock). The Tualatin Celeron is nothing like other celerons, this one actually performs fairly well (much better with the increased bus speed from overclocking) and has 256k of cache.

    I have a chart for advanced settings on the Lin-Lin adapter that would allow you to manually set your Tualatin Celeron at 133MHz detected bus speed and, say, 1.65v core detected. With those base settings, you can overclock further in BIOS.

  4. most of the later 1.2's will make it to 1600mhz so if you have trouble finding 1.1s then that might be an option for you as tualatins arnt being stocked lately. Dont get a 1.3 or 1.4 looking for an overclocking gem because the celerons really need bus speed you arnt likely to get much more than 120mhz bus speed out of the 1.3 or 115 out of the 1.4. So basically the 1.1a is your best option if you have trouble finding that the 1.2 would be your next best bet.

  5. There's a 0.13micron Pentium 3 with 512kb cache, check it here: <A HREF="http://www.jlmtech.net/catalog/detail.php?action2=to_cart&point_specials=0&point_hot=0&p_id=171&name=Regular_Deal_171&osCsid=0359ab2274f87e4b93fa728bb7247e56" target="_new">click here</A>

    Good call

  7. Also my board has a VIA 694X chipset. As I'm still new at this, I assume that means this board is not Slot 1 compatible? (Or do all Intel PIII chips work with any PIII board?)

    (Surprise, surprise: I e-mailed Asus about all this a few days ago and their tech support hasn't gotten back to me yet.)
  8. Ive got an coppermine 933Mhz lying around.. Would be happy to sell it to you, but I live in Sweden so maybe its no good?
  9. Any P3 tualatin chip will work in any P3 tualatin compatable board. Your board will work with the cheaper Tualatin adaptor Crashman suggested. And the 1.26/512 tualatin is my favorite. Mine does 1583@166fsb 1425@150fsb. In a regular desktop board.

  10. Who said anything about Slot-1? The adapter I speak of, as you can <A HREF="http://www.compgeeks.com/details.asp?invtid=S370TUA&cat=CPU" target="_new">See Here</A>, is a Socket 370 to Socket 370 adapter. Intel changed a couple pin definitions on their Tualatin processors to make them NOT WORK in older Socket 370 boards. This adapter reassigns those pins to make the CPU work in older boards.

    This adapter is very handy because it can do several things:
    1.) It can make Tualatin processors work in Coppermine compatable boards like yours.
    2.) It can make Coppermine processors work in Mendicino Celeron boards.
    3.) It has voltage and bus speed detection pins inside the socket (look closely).

    Those pins would be especially handy in your situation for overclocking, because changes in BIOS don't happen until the system boots. So changes at the socket take place imediatly and allow for higher overclocks.

    Also (not pertinent to your board), boards older than yours that didn't support Coppermines will with this adapter, but the voltage pins are needed to change the detected voltage to 1.80v. But you don't need that feature on your board.

    For your board I suggest a Tualatin Celeron 1100@1466MHz. That's because your board is made for 133MHz bus speeds, and the main performance handicap on Tualatin Celerons is their native 100MHz bus. I'd try it using 1.65v core.

    Don't bother emailing Asus because I know more about their boards than they do. Seriously, they don't support adapters and so forth, and rarely retest their boards with higher speed processors. So their knowledge is limited to the technology available way back when your board was a current product.

  11. Got it, I'll go with a Tulatin with a Lin-Lin adapter. But are you recommending a Celeron over a Pentium III? Newegg is offering a brand new PIII/Tulatin here:

    Also (and try not spill your coffee when I say this) suppose I'm not interested in overclocking just yet. How then do the PIII and the Celerons compare on their own merits?

    (I only dare to utter this dire sacrilege on your boards because I see Newegg's also offering a Socket 370 Celeron brand new, but it's one you guys say isn't ideal for overclocking.)

  12. It's all about speed and money for me, that CPU is only 1.13GHz and you're not likely to find RAM that allows it to go much faster. The Tualatin Celeron 1.1 cost around $30, overclocks easily to 1466, and that comes at an easy 133MHz bus speed.

    But hey, feel free to buy the PIII if you feel it suits you best!

  13. Crash would that be the best for my sytem too? I have a asus cusl2 board with a 800mhz/100fsb oc to 912. I want the fastest for the least. My ram is pc133 but obviously it it underclocked. I thought about just upgrading all of it it in a few months but I dont want to spend 700 and with all the new stuff coming out I might wait till the smoke clears. What is the fastest option? Could I get to 1.5+? Some of the tualatins have the 512 cache, should I get one of those or just go with the 256? I know your the man here so just let me know what you would do?
    Thanks
    Thanks
  14. I'd go with the same solution on your far superior motherboard. I can't justify the expense of a PIII 1.4-S with 512k Cache. And with the Tualatin Celerons, the key to performance is bus speed, hence my recommendation for the harder-to-find 1.1GHz version.

  15. Crashman, can you post a link to the Lin-Lin adapter on Compgeeks? I did a product search but couldn't find it.

    BTW, don't get me wrong, your Celeron 1100 overclock is a great idea, but remember I'm the lunkhead who last month needed expert advice on how to get my computer case open. So maybe something like overclocking is, shall we say, a bit beyond my ken?
  16. A Celeron 1100@1466 was what I ran in my main system until someone offered me a P4 2.4B, 512MB PC1066, and an i850E board for $150 a couple years ago. I'd tried a 1.2 and couldn't get similar performance even at 1488MHz, due to bus speed.

    Anyway, I linked <A HREF="http://www.compgeeks.com/details.asp?invtid=S370TUA&cat=CPU" target="_new">Here</A> before, but you must have missed it.
