First overclocked Inspiron 531??

Am I the first to do this? Is it really true? I posted the CPU-Z image so you guys could check it over, it's not edited in ANY way, and I think I crapped myself.

More about first overclocked inspiron
  1. You may well be the first to do it on that machine.
    Is it stable ?
    Is such a small OC worth it ?
  2. the first OC was small just to see if it would work, I got it up to 3GHz stable but for some reason windows 7 keeps rebooting on me without warning, overclocked or not. Temps are fine, in the low to mid 40's. I think it's because I lost my key for the beta :(

    I got an CPU-Z Validator link in my sig now with the new overclock, I'm limited by my RAM though, I can only barely go over 3GHz right now, when I get my new RAM it should be at least a little higher, also I'll get a better cooler, we all know stock sucks :)

    I see you use the same PSU and graphics card I use :) I cant OC my video card beyond 1% for some reason, but overvolting rails 3 and 4 allows me to go slightly higher, just in case you didnt know :kaola:

    PS: For some reason my sig isnt showing up :-\
  3. Didn't have to change any setting's on the psu to be able to overclock my card.
    Did increase the psu's fan speed to help keep the temps as low as possible.
    Do you have the box checked in your profile to always display sig ?
  4. yeah I finally figured out that you have to click the check box in order to display the sig :lol:

    And I meant if you boost the +12v rail to say 12.03, it might help you get a bigger overclock on your card, I wouldnt go much higher than that as mine likes to jump around from 12.00 to 12.13 at the 12.03 setting.

    I've benched mine at 726 / 1200 , don't feel the need for more.
    Have you tried the EVGA voltage Tuner, that may help you get more out of your's.
    By the way, mine's a 65nm C216.
  6. mew905, I may have just missed something but what program did you use to overclock the 531? ClockGen? SetFSB?
  7. DellUser1:
    My card is an MSI model, unfortunately it doesnt feature Voltage modulation capabilities. However it stays at a nice 54C while folding in the summer :)

    AKM880:
    I used nVidia Performance Tools, their latest edition, perhaps accidentally, supports overclocking the I531. If you've got an nVidia board, you can probably overclock too. I've tried all the others, they dont work. I'm using BIOS 1.0.12, unmodified, still under warranty :)
  8. Thanks, I just used ClockGen, however I don't really like it since it overclocks my RAM aswell. Does the Nvdia Performance Tools overclock RAM aswell?
  9. Yes, unfortunately it overclocks using the FSB so RAM speed goes up as well. Bad news is you can't change multipliers on either the CPU nor RAM. Good news is you CAN change timings on the RAM, though the cheap dell-supplied RAM seems to hit its limit around 765MHz, regardless of timing.

    I tried using clock gen before and even selecting a PLL would lock up my PC, maybe they released a new version in the last year and a half? (doubtful).
  10. Yeah, I'm using Crucial RAM and it go to 920Mhz+, just the system becomes unstable at 2.4Ghz.
  11. hey dude i have the same dell model and want to overclok too, could you help? by the way i think that your system still rebooting cause you have the beta, maybe if you install the RC version of win 7 it stops
  12. ^ You have the Inspiron 531 or the Dell Dimension C521.

    sorry i didn't specify, i got the Inspiron 531 with athlon x2 4000+ which runs at 2.10, 3gb ddr2 ram at 667 Mhz, by now i had reach 2.509 with the stock cooler if I increase the speed it turns unstable, as mew905 said he did I also used the envidia perfornmance tool,
    These are the rusults

    do you think this configuration its ok?
    i really dont understand why some times shows 1194.9 and then when im using a heavy program shows 2509.0, is it normal? should i keep this configuration
  14. Its because of the Cool & Quiet technology, it lowers the multiplyer when the full CPU power isn't needed. You can disable it in the BIOS. I did disable it, it made my system unstable.
  15. Nice overclock BTW. Remember to check stability with a program like Prime95 while monitoring temps with something like HWMonitor or SpeedFan,

    Hey thanks for your support, i been using orthos with speedfan to check the temperature, it get 50 °C stressing the cpu and ram for about 1:30 minutes, what do you think? is it ok, by the way when I use HWMonitor says temps are higher, wich one should I trust? speedfan or HWMonitor,
    these are the new results


    this is about temps, who is right?
  17. I trust HWMonitor more, SpeedFan always gives me false readings. I switched to HWMonitor and its fine.

    Yeah Dell computers don't have the best cooling, those temperatures look okay on load. Try to keep it under 60C. I like to stress test for 6hrs+ to ensure complete stability. I ran Prime95 for 25hrs on my Dell. My AMD Sempron 3400+ is stable from 1.8Ghz to 2.3Ghz. Good Job!
  18. I have an inspiron 531...How are you getting into the BIOS?

    I have version 1.0.12.

    I've tried using nVidia Performance tools, but everytime I tried to use the tools, the software crashes because the BIOS is locked down.

    Help?
  19. I'm trying to overclock my dell 531 with the programs mentioned above but they are not working, is there anything the op is doing differently? or is the reason the oc was possible still unknown? I thought it might have been the bios revision 1.0.12 since I have 1.0.13 but I saw some one mention it's not working for them either and they have 1.0.12
  20. I'm thinking about trying the bios mod on this thread, but I'm not sure yet, has anyone tried this?

    Hello!
    I know its 2015 and this post is from 2010 but I'm wondering how this overclock was done. I have an old Dell Inspiron 531 and I want to try overclocking it but I don't know if you're supposed to get a modded BIOS (and if so where to get one) or something else.

    I know it's 2016 and my comment certainly will not help anyone at this point, but today I OC'd the Insipiron 531s with the AMD Athlon 64 X2 5000+ using NVIDIA Performance Tool. I could not safely set the clock speed to go above 224 MHz (x13) without crashing (2.9 GHz). Here's proof. It is noticeably faster, but I am running this machine with a 60 Gb SSD and a fresh install of Windows 7. Also disable AMD Cool'n'Quiet in the BIOS. My temps are fine.

    I realized that I have a dell inspiron 531s with a 4450e but does the same stuff apply. I'm going to try the nvidia performance tools later. Just messing with the old PC before I build my new one next week
