THIS THREAD IS AWESOME FOR OC'ing NOOBS LIKE ME!  Do you guys know of any conflicts using Kevin Keenan's settings with the MSI 645 Ultra mobo?  Also, my BIOS does not have memory voltage/speed options (using most current flash version).  Can I adjust those using XP software?  Thanks in advance.

  • If you mean using a third Party utility or MSI's "Fuzzy Logic" or "PC Alert" to change Voltages....I would just say be careful, and keep an eye on the Voltage Numbers, I say this because like any other program it may go Crazy and take off on you :shocked_anim:And this always seems to happen when one is not Paying Attention....So if you do Up the Voltages, I would keep a sharp look out for any abnormal Temps or readings......Thats why I am a firm believer that all critical hardware changes should only be made via the BIOS, wher you know that a Crazy acting Operating Sysem is not going to send some Overclocking, Overvolting Utility of to make up voltage and FSB numbers by it's own :shocked_anim:.............Sean REILLY875

    Yep, thanks to everybody contributing to this thread.  Thought I never overclock this until my friend told me about the overclocking capability of the 2.4c.

    Had problems initially where I was only able to get 2.6 out of the 2.4c, but upgraded the BIOS on the Neo2 from 1.50 to 1.90 made a world of difference.  Problem before was that I was running at the maximum speed the memory would handle at 220MHz giving me 2.64Ghz, now have it running stable at 3.0GHz and memory at 200MHz.  Temperature hasn't changed changed a bit.

    Enough for now  :-))

    Overclocking w/ this specs
    « Reply #54 on: 13-January-05, 02:52:05 »

    Intel Pentium IV 2.4a Ghz (Prescott) w/ stock cooling
    MSI 865PE Neo2 - Platinum Edition (Latest BIOS)
    2x256mb Geil Value RAM w/ Heat Spreaders PC3200 | 2.5-4-4-8
    GeCube ATI Radeon 9550xt Extreme Edition
    80gb Maxtor IDE Hardisk
    Stock PSU 300w (unrated)

    Can anyone guide me on how to overclock with this processor. I only saw guide to overclocking 2.4c's.

    Thanks in advance  :biggthumbsup:

    Basically the same, but you have 133 fsb as default with that cpu ( multiplier 18x133= 2,4ghz) and 333mhz mem.speed.
    So you cannot raise fsb to 250 (4,5ghz !!), but you could try 156fsb (2,8ghz) or 167fsb (3,0ghz) or any number you want.
    Differant cpu´s have differant oc potential.
    You could start off with mem. auto-setting 1:1 ratio with your DDR400 and see how far the mem. can take the oc.
    You may have to go for 266mhz if your going for high oc - Testing will tell.

    You may need this as well, if you get stuck.
    How to clear the CMOS

    Prescott cpu can run hot, so keep an eye on the cpu temp when overclocking with std. cooler.

    You probably need a better powersupply as well........
    450w and up and some 22a on the 12v line and around 30amps on the 3,3 and 5v lines.

    Many thanks bejon2000 :biggthumbsup: I'm planning to buy a new PSU and HSF. Still have to scour the threads here for tips on what to buy. I'm going for a moderate OC (2.6Ghz) until I can upgrade some of the my sucky components.

    BTW, will application of Arctic Silver 5 be a good idea even if I have stock HSF since my parts won't arrive for another 2 months or so. (shipped from US)

    The arctic silver 5 is  :biggthumbsup:.  Your stock HSF should be ok until you can get something better.  I read somewhere that the 2.4 and 2.8 533 prescotts are not as hot as the 800's ( still hot though).  In fact there are a few articles about oc'ing those chips.  Here is one from [H].

    My temps @ idle is 41-45c (according to MBM5) whilst @ load (NFSU:2, FarCry & Prince of Persia 2) it stays at around 53-55c @ 35-42c ambient. Now that is with stock HSF + whatever paste came in with the Prescott processor. How hot can a prescott go before  :shocking: ?

    YEAH IM CRUISIN
    I GET MY FSB UP TO 230 X 17  ON MY NEO 865 PE    CPU @ 1.7V

    I HAVE GEIL PC 4200 256MB MEM  2 STICKS AT 2.85V
    TIMING @ 2.5-3-3-7   8     I HAVE MEMORY BOOSTER COMIN N E DAY NOW           HOPING TO GO LOWER WITH BOOSTER

    I GOT A 6800 GT  AGP 1.7V.       421 MHZ ON CORE CLOCK  (370MHZ STOCK)
        AND 1.11 GHZ ON MEM CORE CLOCK   (1 GHZ  IS STOCK)

    I HAVE A SWIFTECH WATER 650 PUMP  AND A SOLID COPPER BLOCK ON CPU
    I HAVE THE 120 RADIATOR WITH A 120 FAN  FROM CRAZYPC.COM (THE KIT)
    MY CPU TEMPS IDLE AT 25c - 26c  AND SYSTEM TEMPS STAY 23c
    B 4 I GOT THE KIT I WAS 45c - 48c AT IDLE

    IM GONNA GET 2 MORE BLOCKS - GCARD AND INTEL CHIP  AND A FEW MORE RADIATORS  AND MORE TUBING TO DROP IN ICE OR PUT IN ICEBOX
    THIS THING JUS CRUISES

    I ALSO HAVE 7 FANS  HANGIN ROUND  IT LOOKS LIKE A TOTAL MESS  
    BUT IT TOTALLY ROCKS



    IF U WANNA SEE A PICTURE  EMAIL ME

    WHEN THIS THING SELF ADJUSTS  I HAVE SEEN IT AT 4.15GHZ

    Ok I tried to OC my rig today, coz I bought my CPU at work(good AC, low temps). So I tried upping the FSB, 140...goood, 150...good....155 GOOD! Everything is cool, no glitches whatsoever(no torture test yet) but the thing that scared me the most was at idle (35-37c) my HSF just stopped spinning..EEEKK! Quickly pushed power button, then the fans started running again.

    Then I tried restarting it again, everything is good, boots up to XP desktop. The thing is, when my PC idles, the HSF just stops spinning...I tried waiting for it to run again (38c...40c....42c...) then I just pushed the power button out of sissyness. Is this normal? I set my speedfan desired temp at 40c & check the automatic fan control. I really think it is speed fans fault. It shuts down the fans when the temp is lower that desired temp. Is my suspicion right?

    MAT/DOT Set to OFF
    DRAM FREQUENCY = 333
    SPREAD SPECTRUM = OFF
    ADJUST CPU CLOCK = 267
    AGP/PCI FREQUENCY = 66/33 or whatever is closest to that
    CPU VCORE ADJ = no
    CPU VCORE = 1.5
    DDR VOLTAGE = 2.5
    AGP VOLTAGE = 1.5

    Yes, i've seen that option all fans are set to 100%.  I enabled variable(or automatic) fan speed at my first try though. Anyway, I OCed it again but this time, I disabled the variable(or automatic) fan speed in speedfan. So far, everything is stable. Ran prime95, priority 9 for six hours. 100% CPU load @ 50c, idle @ 42-45c, 27-30c ambient.

    Gosh...I wish I have an AC at my place.  ;-))

    Hi,

    If I could add just a small note: If you set your SATA to Keep Enabled, you can have your AGP/PCI slot locked to 66/66/33/33. I read this somewhere in one of the forums. It works. Thanks for the post . . . :)

    neo2-pfisr

    Went:

    333 mem
    no dot
    dram set to auto
    vcore 1.6v
    250fsb (from 2.8ghz to 3.3ghz)
    agp 66/33
    ddr 2.65v
    agp 1.5v

    bluescreen right before windows would have started.

    lowered fsb to 240 (3.22ghz)

    running fine so far, 30 minutes into a burnin with error checking on.  40C temps with burnin running.

    think if i pushed my vcore up a bit more i could get the 250 stable?  or at least to boot so i can test if it's stable? :)

    excellent guide btw.  i just want to push it til i can't push it anymore.  heh heh.
