« on: 16-March-04, 17:16:38 »

ok so based on your experience, i want to overclock my cpu a ton because of my watercooling but like i have said before my windows locks and stuff at 3200 so is there is a software problem or what and how should i fix it so i can over clock more?

  • You just might be at the CPU's Overhead limit......Have you tried more V-Core Voltage?>>>>> https://forum-en.msi.com/index.php?threadid=40413&sid=  ......But to tell you the truth, I don't think that you are going to get any More MHZ out of your XP-2500..........Sean

    i have no idea about your overclocking history but i assume you know the basics, and if you do , then follow this simple guide :

    Step 1 : Check current speed, and set the FSB:DRAM Ratio to 1:1
    Step 2: : Lower the CPU Multiplier to allow more headroom for ocing
    Step 3 : Start raising the FSB little by little keeping in mind you need to keep pumping juice (voltage) to your stuff
    Step 4 : When you reach your highest unstable FSB point, check if you can raise chipset voltage, if you cant, clock back down a bit , and this is your highest FSB
    Step 5: Start raising the CPU Multiplier in 0.5 increments, and keep pumping voltage to that.
    Step 6: When you reach your highest unstable multiplier, add Vcore, when you reach a point where it doesnt help, clock back down to a stable CPU multiplier.
    Step 7 : While doing all this monitor temperatures constantly
    Step 8 : When youve reached a combination of highest Stable FSB and Highest Stable CPU Multiplier, take a look at your ram timings and try tightening your timings, the tighter the timings, the better performance.

    After all of those are at their peak levels, you are now done, and can go into windows and benchmark, GOOD LUCK! and dont  fry anything !

    hope this is helpful...

    If I'm reading your specs right you have PC2100 Ram. If this is the case you are oc'ing your ram just running the cpu at stock speed unless you have changed the FSB/Dram ratio to compensate. The 2100 ram is rated at 266fsb. To fully get best oc'ing from the 2500+ you need at least PC3200 ram it's rated to 400fsb or you can get PC3500 or PC4000 they are rated higher.  I have PC2700 rated at 333fsb and can only oc my 2500+ to about 175x2 to get stable performance. I did raise my dram voltage and cpu vcore voltage and got it to run at 3200+ but had memory errors in memtest86+ and prime95 would only run a few minutes before it reported hardware failure. I have corsair xms PC3200 ram on way so I can get my 2500+ to run at 3200+ speeds. Also you need a really good power supply.  I'm relatively new to oc'ing but my research in these forums and trial and error has helped me to understand oc'ing better.
