Q6600 freezes with Vapochill LS

Hi, I used to have a H50 for my Q6600 @ 3.6GHz with 1.48V core, FSB 450MHz x 8, everything was great, stable with occt, ibt and overnight prime.

Last month I got a new Vapochill for $250 and installed it and then... overclocking isn't now possible, it just freezes always, without overclock there's no problem, I already try to redo my overclock, can't get my FSB to 450MHz, just to 400MHz x 6 and with issues.

Those anybody have an idea what's happening? is it a cold bug or something? I don't want to go back to the H50....

  1. Did you isolate the mobo?
  2. Yep, all surroundings of the cpu with kneaded rubber and neoprene
  3. So you spend $250 to cool a Q6600? Really?

    Sounds like your memory settings have changed and you didn't realize it, this would cause our overclock to fail.

    Check that your memory isn't running faster than it's designed to run by changing the cpu/fsb ratio.

    Assuming your using ddr2-800, it would make sense the 400mhz fsb works because then your ram is 800mhz. If you raised it to 450 and didn't change the ratio your 800mhz ram would be running at 900mhz.
  4. I run a Q6600 with DDR3-1600...LGA775 and some chipsets supported it...just FYI.

    Yes I do, and no, memory clock doesn't change, I leave it at stock speed to discard it from the problem
  6. That Q6600 is an excellente CPU and overclock very well

    I agree, and i have a G0 so I have no idea what's happening with phase change....
  8. Maybe a re-install process? What RAM are you running?

    Windows re-install???, I'm running two 2GB PC2-6400
  10. No, vapochill re-install.
  11. I´ve already mount and re-mounted it, always the same....
    BIOS reporting -36ºC ~ -40ºC
  12. What RAM are you using?

    Well, after hours of errors now I can see the light!, I have to adjust GTLREF lanes 0 and 3 and now my 3.6GHz OC it's back, for anyone who need a guide to adjust them, I used this:

    Thanks all of you
  14. So you spent $250 to overclock a Q6600 to 3.6ghz?

    Really?
  15. Test the rig out of the case.
  16. Well those are very rare units but when they work there is nothing out there like them even traditional water cooling doesn't come close to the thermal improvements. I don't see how people don't know what they are after all the rage generated years ago about them since the socket7/slot1 days up through to the 775 era.

    Today after 1 hour of OCCT, 20 passes of IBT and more than 15 hours of Blend Prime 95, I finally achieve 4 rock solid GHz in my Q6600 with 1.552 VCore and a max temp of 7C on IBT Load.

    Everybody dislikes the vapochill but I think it's great and not very very expensive today.

    Thanks everybody and trust me, that guide for GTLREF is awesome, tunning it, overclock, soft test with 5 pases of ibt to quick check stability and then one hour of occt, then 20 pases of ibt and last, prime 95 with one or two steps up in vcore and that's it, a + 60% OC in one day!!
