More about prime95 passed freeze
  1. It failed i think, but obviously if it failed, Prime95 wouldnt be able to tell you (because it has froozen)

    I get the same thing when overclocking my ci7 920, It doesnt blue screen, the screen just goes black and nothing else happens, I have to hit the restart button.

    So your OC isnt stable, although it must be close looking at how many passes it has on prime95.

    Did you run it for 17 hours? (sorry im crap at maths.)
  2. ^Yep, you need to raise the vcore a little bit.
  3. yeah i think,, i started last night at 10:30
    as u can see it stop recording at 4:48pm
    so 18 hours stable!
    sufficient for me,, thou!

    so i'll increase the vcore?
    getting it to 1.3?


    btw, my temps are 67-66-66-59
    that fourth core is cooler than the other!

    heatsink needs to be lapped or just leave it?
    or change thermal pste?
  4. Well i mean, its pretty damn stable as is . It already passed 18 hours so, unless you want it 100 percent stable i would leave it as is.

    But yes, if you wanted it more stable then increase it to 1.3 or so.

    It is normal to see differences in your core temps. ive seen as high as a 12c difference in core temps ;).
  5. ok so no need to touch my heatsink!

    naa if its stable for 18 hours i am more than satisfied!


    never use my pc longer than 10 hours!
  6. Yeah, not to mention prime 95 stresses the CPU more than any game or program you will be running. Na, no need to touch the HSF. Your temps look good and that's what id be concerned with more than difference between cores.

    Remember if you re-seat the heat sink you could also raise the temperatures of all the cores which would be worse.
  7. thanks man!

    my next goal is to reach 29k 3dmark06 with my 5870!

    well thanks again!
  8. Yeah, no problem mate.

    Thats a nice goal, whats your CPU overclocking goal?

    Post your overclock in this new thread:
    http://www.tomshardware.com/forum/256708-29-core-overclocking-club

    Im trying to get people to start competing with each other to move up in the ranks, mebe youd like to join?
  9. well 4.0ghz with air is my goal!

    i'll try to join
    post my specs
  10. What speed is your CPU at now? I think you can go a lot higher especially since its only at 1.29v.

    BTW thanks for joining, trying to get as many people as possible.

    For help on overclocking i posted alot of useful information over here:
    http://www.tomshardware.com/forum/256021-29-core-overclocking-what
  11. 200 bclck x20= 4ghz

    i cant even boot at 4.6ghz with 1.400 vcore
  12. You need to tweak other things. Just raise it little by little. I usually start raising my bclock by 5 mhz each time then when i cant boot i raise the voltage a little.

    Srsly dude, the thread i posted earlier helps alot.
  13. i read it man, but i just cant boot, windows boot passed but then, black screen freeze, lcd poster working though, so i guess it's os problem
  14. na, its not the OS. You just need to change some of your voltages.
  15. i need red bull here,, my eyes keeps clocing!
    hahaha

    well try and try
