Coppermine CPU for P2B

I just read a post from someone who says he upgraded the BIOS of his Abit BH6 board to support a Slot-1 P3-850 CuMine (100Mhz FSB).

Now I've checked with the manufacturer of my board (Asus) to see if I could do the same because P2B is a BX board too. The latest BIOS release from Asus shows support for CuMine CPUs, but in the features of the P2B board Asus says that it supports P3 450Mhz to 600Mhz+.

What does the "+" really means? Does that mean I can get a 800 or 850Mhz CuMine P3 (100Mhz FSB)?
I'm asking you guys because Asus is kinda slow to answer back.

  1. 600+ means, 'we have BIOS to handle ANY internal multiplier on PIII E chips, period' Your in luck. Flash your BIOS, buy an ASUS S370-DL CPU card, and plug-in that BadAss Cumine. But save $... buy the 800E (the 100MHz version, fer about 170 bucks !!!), then start pushing the envelope.. Your P3 will either boot or not boot as you increase FSB. The 800, with ORB, should easily get you to 1066MHz/133FSB, as long as your ram is there at PC133, or PC100, if your lucky. Mine is running at 1120MHz (140FSB). Stays below 50degrees C. When you reach the wall, just back it off, and enjoy the speed. Raise the voltage slightly, then a week later, push it up another notch. You'll probably get even more !

    The ORB is enough, and any goof ball can install it.

    Deaze PIII chips are ragin' BX upgrades !!

    Have fun !

  2. Someone posted that he has a Slot-1 P3 CuMine 850@100Mhz installed on an Abit BH6. Does that CPU really exist? I have my doubts though!
    If that really exists, I'll use that instead of getting a S370-Slot1 converter (if I can find that CPU at all).

  3. Check yer bookmarks bro. The 850 is the top-end of the 100MHz FSB-based Cumine line. As such, it's $100 more than the 800, which, as you can see by my earlier post, has good potential for overclockin'.

  5. Gee, for the BX board I would get the fastest E processor available, as going above 100 will overclock the AGP. I was informed a few weeks ago that the BX does indeed support 1/4 PCI clock, so 133 would only overclock the AGP with the 1/4 divider set on the PCI, which is fine with a GeForce card. If you really want the best performance I STRONGLY suggest the 700, as it overclocks just as high as the 800 (yes it does) and will allow you to use higher bus settings.

    Suicide is painless...........
  6. You are probably right, crashman, the 700E posts a higher average O/C than the 800 on

    I probably got a lucky chip.
  7. Sorry, I am wrong. PIII E chips have just hit the 1GHz mark. Available at one vender I know of ( in both SECC and PPGA versions.

    Just can't keep up.

  9. So let me get this straight.

    You're saying that I can overclock my FSB to 133Mhz and that won't affect my PCI cards (of which I have 4). Will the 1/4 divider be set automatically or is there a procedure to change this divider? I also have 2 ISA cards (modem and parallel port card, since all my PCI slots are used I had no choice but to buy ISA modem). Would a 133FSB affect them? Since I've got a Guillemot (Hercules) GF2MX card in the AGP, I guess it won't have any problem dealing with the AGP bus increase. Further, I've got a PC133 RAM module, so there's no problem there.

    Now, all I have to do is increase the FSB to 133Mhz and everything should go fine with a Coppermine processor. Is that right?

    Would that apply to a Katmai CPU?

    - Better go Green than Blue!
  10. I was able to do just that.. 100to133MHz FSB and boot. But, you can try some intermediate settings if they are available in your BIOS or through dipswitches.

    If your lucky, your PCI and ISA cards WILL tolerate some OC. I am running 140MHz FSB and 35MHz PCI (94MHz AGP). This setting is available through dipswitches on my ASUS P3B-F (I've never bothered to use the FSB/PCI/AGP settings in the BIOS), becuase I haven't needed to.

    Have fun !

    And remember,
    AMD stands for Anyday Might Die, toastwise.
  11. IF you're lucky is the key phrase.

    I sure as heck wouldn't bet on being able to overclock very much with that many cards involved. (Especially with ISA cards involved.)

    You might get lucky. You might be able to overclock that high. And you might not. If you want to make sure that everything works then just buy the fastest processor you can and don't overclock it.

    I'm all for overclocking.

    But sometimes my hardware isn't.


    - Sanity is purely based on point-of-view.
  12. I find with good quality cards (ISA/PCI/whatever) you can get up to about 20% more. I run my PIII-500 (600) system at 120FSB (instead of 100) and don't have any problems with anything.

    - JW
  13. You may want to verify this, but I believe your ISA clock is dependant on you PCI clock. As for adjusting the PCI divider, check your manual, it should be available in BIOS but maybe by jumper too. So verify the ISA speed issue, and everything else is fine. I would not use the Katmai, as it is not available at higher speeds and does not overclock as well. For the PIII, I would raise the voltage by .1v to assure stability, then play with it later to get the lowest stable voltage. For the cBO stepping this would mean going from 1.65v to 1.75v.

    Suicide is painless...........
  14. I believe the ISA bus is controlled by the PCI bus, so adjusting the PCI bus adjusts the ISA bus for you.

    And IF the motherboard does support a PCI bus adjustment so that you can keep it running in-spec at 133MHz FSB, THEN I see no problems for your cards if you overclock.

    But, I wasn't aware that any BX motherboards supported that divider because they aren't specced for 133MHz.

    - Sanity is purely based on point-of-view.
  15. My board doesn't support such low voltages.

    - Better go Green than Blue!
  16. My P3B provides 33MHz PCI with 133MHz FSB.
    It would be a surprise if the P2B doesn't.
    If you don't have the manual, look on the ASUS website.

    I have a network card in the ISA slot, and it function without errors. However, all of my cards are working at 35MHz now: 140FSB/35PCI/94AGP. I don't know what the ISA slot is doing, but I don't think that a 140FSB can be turned into 33MHz for the ISA, so my guess is that it is running 35MHz as well.

    Even if you can't get to 133MHz with a PIIIE chip, there are a number of options available on your P2B board. Then again, most of the E chips WILL post with 133MHz FSB. Check out for average posts for CPUs. You will see that there are few posting less than 133. When they can't get to 133, it is usually not the chip, but the board. The motherboard is part of each entry, so you can see if anyone couldn't get their P2B to work at 133 with a PIIIE chip.

    and remember,
    AMD is an acronym: Another Mindblowing Disaster (toastwize)
  17. Well, my real question is since Asus doesn't explicitly specify that P2B actually supports P3E chips, I just want to make sure that it is OK for me to go ahead and buy a Slot-1 P3E CPU SECC2 even if I choose not to overclock it.

    Would I need to mess with voltages? My board doesn't seem to have any jumpers for Voltage settings according to the latest revision of the Manual supplied by Asus.

    - Better go Green than Blue!
  18. That's an interesting question: Does voltage even vary for Slot-1 chips?

    - Sanity is purely based on point-of-view.
  19. I sure hope it doesn't. That would be a load off my mind.

    - Better go Green than Blue!
  20. I was informed of this divider by several BX specialist. It turns out that, at the time of it's design, Intel included it so that you could originally run your PCI bus at 25MHz. For what reason, I don't know, but it's a handy feature for overclockers.

    Suicide is painless...........
  21. Shazam,

    The ASUS S370-DL CPU converter card (slotket, it's $15) comes with voltage jumpers set to "CPU default". PPGA chips drop right into the zif socket, and their are no capacitors to block a fan. Also NO adjustments are necessary for standard installation. Actually, my 700E is running 980MHz at the default voltage, with no problems.

    But, changing the voltage is a snap (jumpers), and there are small incements so that you can tweak it carefully if you need to raise the voltage for overclocking.
  22. That seems like a pretty odd excuse to have put it in there. Who would want to underclock their PCI bus? I wonder if that was actually a front for some engineer's desires for an overclockable board. :)

    - Sanity is purely based on point-of-view.
  23. According to Asus, I can't run a Coppermine CPU on my P2B because my board rev. is 1.02 and they require 1.12. Look here:

    - Better go Green than Blue!
  24. SECC2 (slot 1) voltages:

    kB0 stepping:
    2.00V: 450, 500, 533, 550

    kC0 stepping:
    2.05V: 600, 600B
    2.00V: 450, 500, 533, 550

    cA2 stepping:
    1.65V: 533EB, 550E, 600E, 600EB, 650, 667, 700, 733, 750, 800, 800EB, 850, 866

    cB0 stepping:
    1.65V: 533EB, 550E, 600E, 600EB, 650, 667, 700, 733, 750, 800, 800EB, 850, 866
    1.70V: 933, 1000, 1000B

    cC0 stepping:
    1.70V: 533EB, 550E, 600E, 600EB, 650, 667, 700, 733, 750, 800, 800EB, 850, 866, 933, 1000, 1000B
    1.80V: 1130

    and I think that's it...

  25. There is a company the makes an adaptor to run coppermine in non-copermin boards, I saw it mentioned on some abit board. If you can't find a reasonable solution, you might be better off replacing the motherboard and buying a processor at the same time. BTW Intel just dropped their prices, if you want to stay with intel I suggest the CUSL2-C.

    Suicide is painless...........
  26. It's not that I want to stick with Intel, I just want the best bang for my buck. Now I don't want to offend any Intel fan (and you as well, as I'm aware of your fondness for Intel products) but if I decide to change board+CPU, I'll go AMD. I'm not a fan of Intel nor am I a fan of AMD, I'm a fan of good value and for the time being Good Value = AMD.

    I just wanted to upgrade a bit while waiting for a decent DDR solution that has proven its reliability.

  27. Question:
    Which ASUS M/Bs can support PIII 650/700/750/800 (100MHz) CPU?

    To support Intel CPU with S370 FCPGA form factor on ASUS slot1 M/Bs, a S370-133 adapter card is required.

    It's not clear if you need rev1.12 only to run a FC-PGA coppermine with a S370-133 adaptor, or if you need rev1.12 to run any coppermine.

    Since the multiplier is locked it is not the multiplier that would be the problem but the voltage. Reading through the P2B manual I can't see a way to change the voltage on the P2Bs unless you can change the voltage in BIOS. Normally it autodetects the required voltage but the early revision boards may not support the lower voltages required for the newer chips. A 1.70V chip prob wouldn't last long at 2.00V.

    BTW: Clonan - Our P3B-Fs will run them because we can change the voltage and FSB speed in BIOS. That's the difference between P3B and P2B boards.

  28. I love AMD, but have founded a grassroots movement against VIA for the problems they have. If you want to go AMD I suggest the new Iwill DDR board, it has the new ALi chipset on it. Tom reviewed it a few weeks ago, it seems to be a great overclockers board as well.

    Suicide is painless...........
  29. Exactly.
    That's what kept me from buying that P3E chip for a while.
    If someone out there can assure me that a P2B CAN without a doubt support a Coppermine CPU (Slot-1 or S370) I'd go for it.
    I just don't want to buy a new MoBo now.

  31. Why not just wait for a few months. I mean why spend all that money to upgrade a system that you'll ditch for a better one soon anyway?

    That or just go with whatever is offered currently for DDR SDRAM motherboards if you really can't wait.

  39. That IS good news for Shazam ! Midrange PIIIs are really cheap now.

    I just built another BX system this weekend for work:
    ASUS P3B-F. It's one of the last available, I think. I did it because P4 is clearly not affordable or faster, but also because I keep seeing heat and stability problems with VIA/AMD setups. I know MANY have no problems with VIA/AMD, but I see few posts about heating problems with PIII (the latest 700E posting seems to be a loner). Price was a major factor as well, so here's what I ended up getting:

    ELSA Gladiac MX 32SDR
    ASUS S370-DL
    WDBA205 7200 (puuled from an upgrade at home)
    2x128Mb CAS3 'midgrade' RAM (NEC chips on it)
    Diamond MX400
    InWin Mid 250W
    CL52x IDE
    NEC IDE zip100
    Optiquest Q95-2 (19")
    Win2000Pro license (upgrade)
    Office 2000 (upgrade)
    Photoshop (upgrade)
    The total before software (but including fans and input devices) was below $1350.

    I got another 800E, based on phenomenal luck with an earlier purchase (below 50C and stable at 140FSB/1120MHz). That's 40% over nominal processor speed (and AGP), and the PCI bus is even stably overclocked ! But this new 800E doesn't like to go that fast. This morning, I loaded system and software (set at nominal specs). It was running cool 24-28C.

    Now, it is posting 992 (124FSB/31PCI setting). The next step available (BIOS OR dipswitches) is 133/33, and it just isn't making it.

    I probably could have done better with the 700E (have one at 980MHz:140FSB/35PCI/94AGP). I bothered with a stability cert on this one (13hrs and a few minutes with no errors).

    Oh well. Still, 992 isn't bad

    By the way, Shazam, it runs Descent3 and Unreal Tournament Nicely ! And it even loaded and runs that old DOS/Win game 'Forsaken' perfectly. Never thought I could do that with NT5 !
  40. Hey clonan: what stepping are the CPUs?

    Sisoft Sandra will tell you under "CPU and BIOS info - Stepping Mask: xX#". I'm just wondering if some steppings overclock better then others.
