Ram causing BSOD on Win7 64 bit

Hi all , about 9 months ago i did my first build as follows
i5 750 , 4 gig gskill ram , p55 ud3 , ati radeon hd5850 , win 7 64 bit , mostly for gaming .
I have made sure my updates and drivers are always current

Since day one i have had BSOD constantly , at least one a day . I replaced the motherboard with a gigabyte p55 ud5 , replaced the graphics card with another hd5850 , got a good power supply with a corsiar tx 750 watt . I still got blue screens , normally with differant reasons .

so i am now running I5 750 , crossfire hd5850's , corsair 750 watt , gigabyte p55 ud5 .

I have just taken out one stick of ram and now I no longer getting any blue screens . I have tested both sticks of ram and mem test says that they are good , but as soon as I add therm both back to slots 1 & 3 , i start getting the blue screens again .

Can someone tell me what is going on with that ? Can i run both of them out of differant slots eg 1 and 4 or 3 and 4 ?

Will buying some new ram solve the problem? Any ideas and thoughts

  1. Drop the G.Skill RAM and replace it with Corsair XMS3 instead. Originally I thought that the Asus boards didnt like the Ripjaws, but from the problems you have described it looks like that Asus doesnt like G.Skill period.
  2. Asus board ? but I have been using a gigabyte motherboard with g skill rippjaws

    After a lot of reading and research it seems to effect a lot of people .

    I am about to try increasing the ram voltage to 1.6 and see if that will make both sticks stable .

    If not I will invest in the corsair ram u have mentioned .
  3. With one stick, it's okay to use the first slot. However, with two sticks of RAM they should go into slots 2 and 4. Try that and report back.
  4. HI all ,
    I have increased the ddram voltage in the bios from 1.5 volts to 1.6 volts . It says on the specs for the ram 1.6 volt . I left the computer on all night and no crashes , usually leaving it on all night would crash it . I also ran a stress test on the ram and cpu and no crashes either .
    Hopefully after all this time the problem is now solved .

    If the memory is spec'd for 1.6V, it makes sense to set it at 1.6V. While you're at it, you may want to manually set the timings as well (for example, 9-9-9-24 or whatever your sticks are rated at).
  6. Hey ,
    I dont know all that much about computers and this was my first build . I would have assumed when i stick the ram in the slots then the mother board should send the correct voltage , I guess that doesnt happen all the time , ?? . the ram timings are at 9-9-9-24 .
    Since I changed the voltage everything is running perfectly and not one single crash yet ......finally :lol:

    Yeah, under or over voltage will have the same affect, but unless you changed the DRAM Frequency in the BIOS the RAM @ SPD {stock/default} 'should' run at 1.50v.

    If you post the RAM part-number or preferably the link I or most anyone here can walk you though the correct BIOS settings for you RAM. Setting them properly will further aide in stability and performance.

    Good Luck!

    Use slots 1 & 3:
