Oc'ed my I7 930 to 4ghz

I want to make sure my temps seem ok and my setting are ok as well. Ive never oc'ed this thing to 4 ghz had it stable at 3.4ghz.
Im using an Asus p6tse
My Ram is kingston hyperX 1600 8-8-8-24

BCLK 190
DRAM frequency 1523
CPU voltage 1.250000
QPI/DRAM core voltage 1.30000

My idle temps are
45c

I ran prime 95 the test got to test 7 and my pc restarted itself. Temps were 85c.

    I wouldn't be happy with those temps.
  2. Is there any way i can get them down? Most of the time my pc stays at about 42c anyways at 3.4ghz. The cpu cooler im using is: http://www.newegg.com/Product/Product.aspx?Item=N82E16835118046
  3. Should i be looking into purchasing a better hsf?

    A lot of things affect temps. The chips could just run hot, high ambient air temp, case air flow, heat sink design, proper seating of the seatsink/thermal material, and more.

    Do easy stuff first.

    Examine your case for air flow obstructions. See what you can do about room air temp/air flow, if its an issue.

    Drop your system back to stock and see what temps you get then. Do it in 200 Mhz increments and see what temp reading you get at each speed. If its still a little high at each speed, you might have a hot running chip or a heatsink/thermal material issue.

    Better heatsink would help, but I would try that last.

    However, my guts says something is wrong with the heatsink/thermal material. 1.25v is not very much. Temps seem awfully for that voltage setting.
  5. awesome, ill try reapplying thermal compound.
  6. its warmed up in my room since before so my temps are about the same. Going between 41-45c. Reapplied thermal compound and resat my HSF.
  7. Should i be using CPU ratio 21 or 22?
  8. when going for a high overclock you deff. want to use the highest multiplier possible. A higher BCLK will just make things less stable.
  9. awesome ty
  10. set the multiplier to 22 and set the BCLK to 173(3.8ghz) running good temps are about the same.
  11. ^ Yeah it seems 3.8 is the sweet spot for overclocking the first gen i7's. Some get over or around 4.0GHZ but usually with quite a bit more voltage than it's worth.
  12. dont forget prime 95 puts your cpu through more stress than real world stuff--whats the cpu temp at under normal stuff like heavy gaming etc?

    just to give a rough comparision--though there are variables like room temperature--case etc

    i am at 41c idle and about 67c when under load from heavy gaming etc

    i7 920 at 4.2ghz 1.3v so your voltage is really good at 1.25v--200bclk x 21 12gb of 1600mhz ram-- qpi 1.355v

  13. Played Dead island for about an hour temps were between 58-60c idling at 45-48c
  14. every one has a different opinion on it but i dont run prime 95 as it puts your cpu under stress it not going to see in real life use

    to me my overclock is stable if it doesnt crash when doing the stuff i normally do like heavy gaming and video encoding etc

    those temps dont look seriously bad--you could change your heatsink if it bothers you

    There's something to what your saying, but it's not the full picture. You can be slightly unstable depending on what your running and not crash. Now that's great if you don't crash, but you will over time corrupt data on the drives. If your one one of those people that format often, then it's not a problem. If you don't, then making sure the system is fully stable is important. Just my 2 cents.
