Just Overclocked a p4 2.4 800FSB

Before I say anything I must tell you all that I am a newbie to overclocking cpu's.

In my BIOS I saw that both my FSB and my ram were running at 200 mhz so that is a ratio of 1.1. I boosted up the FSB to 250 mhz hoping to get a ratio of 5:4 (250/200). Well after I did this and booted up it went up to 3 ghz so I assumed that I was successful with such little effort. However, I noticed that my ram is now running at 166 mhz which means that it went down from 200 for some reason. My RAM is now running slower than it was before?? How come it didn't stay at 200mhz when I upped the FSB? Is there a way to get it back to 200MHZ? I tried moving it around in the BIOS but I couldn't, it just said auto.

Thank you in Advance.

  1. Download a program called CPUZ from www.cpuid.com click on the memory section and see if it actually is 166mhz or 200mhz. Bios could mistake that sometimes.

  2. That's the program that I was using. It says the frequency is 166.7 mhz:( What can I do? Thank you for your time.
  3. Could you give us the rest of your system specs?

  4. Pentium 4 2.4 GHZ (OC @3GHZ) 800FSB (Now 1000MHZ)
    ASUS P4P800
    512 MB DDR-SDRAM PC3200
    Radeon 9500 PRO
    Windows XP Pro Service Pack 1
    80 GB Hard Drive

    That's all the specs I know right now, if you need anything else let me know.
  5. Okay then great, go in your bios, in the jumper free section change Dram frequency to 320mhz. Then at 250mhz, your ram'll be running at 200mhz.

  6. scottchen is right. The DDR MHz rating in BIOS tells you the frequency based on the base frequency of your CPU. So the 400 setting is appropriate for 1:1 with an 800 bus, both have a 200MHz clock. The 320MHz setting actually forces the true 5:4 ratio on an 800 bus CPU, and overclocking to 250 gives your RAM 200 (DDR400).

  7. Thanks a lot Scottchen. DRAM is running at 200 mhz again:)
  8. Good, now you may want to overclock that 9500pro a bit, it's a very overclockable card, download the omega drivers from <A HREF="http://www.driverheaven.net" target="_new">driverheaven</A> then overclock, i've heard that most 9500pro's VPU can reach 340-350mhz on stock. And depending what kind of ram you have, i'm sure you can break the 310mhz barrier.

  9. Wow thanks a lot man I did what you said and I notice an improvement.
  10. Where did you get it to?

  11. At first I tried to set it at 340 (core) 340 (memory) but that didn't work out too well... the graphics in my games became distorted so i lowered it to 317/317 and it's doing fine.

    Did I do it right? Should the core and the memory be the same value?
  12. They don't have to be syncronized, so push core up high. It's your ram which can't handle the high frequency. Push core to 340, and leave ram at 317.

  13. I am experiencing an annoying problem right now. I downloaded and installed the latest Omega Drivers and everytime I boot up the computer or open up a program/application, a box pops up and says "Please wait while installing Rad Linker, please wait while Windows configures Rad Linker" This happens all the time... when I open internet explorer, when I open a game up, when I play a song from my music folder etc. Argggghhh.
  14. sounds like adware

  15. Hi I got almost same setup; I have P42.6C @ 3.25, P4C800Deluxe, 2048 DDR-3200 400MHZ, GF FX5600, 200 HD 7200rpm, and Antec 550 TPower

    Now I never OC and I don’t know nothing about, what a need to know if I for this setup I need some extra cooler or I will be ok just with out one,and my CPU-Core I have at 1.75, is that ok or should I turn down

    Sorry about my ingles

    Oh i forgot my tem MB-33C , CPU 43C

    Wow that's one cool mobo you got!!

    I've mentioned in my guide, if you're planning to keep your chip for about a year, then you can go up to 1.775, at 1.8V the chip dies insanely quick. Stay under 1.7V if you want to actually keep the chip for more than a year.

  17. First my system:
    Intel P4 2.4GHz(c)800FSB
    4x256MB Corsair PC3200 DDR ram
    ASUS P4P800 MB
    ATI Radeon 9700 Pro

    Ive never had the need nor the desire to overclock my cpu before now. That said, I now have the urge. Based on the above comments, I have a rough idea on how to overclock my system. My main concerns are with keeping the ram running in both DUAL CHANNEL and at its normal speed. Even more importantly, IF I overclock my 2.4c to approximately 3.0GHz and keep my ram running at ~200MHz... can this be accomplished with stock cooling and without significantly decreasing the lifespan of my cpu?

    I would really appreciate any input you may have.
  18. You can run at 250FSB, 3.0ghz, 200mhz on the ram, absolutely fine, you probably get there on stock voltage. With stockcooling, you shouldn't go beyond 1.65Vcore, if you feel like pumping a little extra out of the CPU.
