i7 930 Sooo Close to 4.2

I just built a new pc and just wanted your opinions to make sure I'm going in the right direction. This is really my first time overclocking a new chip.

Specs

• i7 930 (Hyper 212+ HSF)
• Asus P6T
• Corsair 1600 XMS memory 6gb
• 690 II Basic (2 140mm exhaust fans top, 120mm front intake, 120 rear exhaust, 120mm bottom left exhaust)
• EVGA 470 superclocked

This is how I have the bios set

My core temperatures range from 38*c to 44*c at idle
I ran Intel Burn Test on Standard and High and my temps were in the 70*C to 74*C range

During Heaven Benchmark I range from 46 to 53*C Max temps

Some additional information

at the stock clock speed i run at 34-36 idle and with the intel burn test im in the mid 50's

Also is it safe to run the dram voltage at 1.66? it says the max should be 1.65 however it automatically selects this when you chose x.m.p.

Thanks

You can run the RAM anywhere between 1.64 to 1.66v and its safe. Also, change your CPU voltage to the lowest value you can get... 1.24v should work for you at 3.5GHz. If it doesn't, up it a tiny bit until its stable.

I wish i had a GTX470

Too many "auto" settings there for my linking.

Give our guide (linked in my sig) a read through and spend a little more time with it, you'll be at 4GHz in no time

I will check out the guide, I actually bookmarked it yesterday. As far as temperatures go do mine seem normal and healthy?

Temps look good.. idle in the 40s is fine and max out below 80 is good too..

once you start breaking the 80C load mark is when you need to decide if you're ok with the OC or not.. imo I try not to hit 80 and sit around the 75-78 mark if possible..

Id also not use XMP profile.. you can manually set your clocks for the ram

 

[exedotbat]

should speed step be enabled?

 

[hieu2ueih]

Turn speedstep off as you test for stability.

 

[Shootingblanks]

Dump XMP profile. Set Dimm voltage to 1.65volts. Also set your vcore to the lowest possible setting that your overclock is stable. At 4.125GHz I use 1.45 vcore and my temps have never broken 76 degrees using world community grid. I tested 50 loops of linx then ran 48 hours of WCG for stability. I don't care for prime 95 anymore since there are harder stress test /programs out there.

 

[exedotbat]

Any reason why i can't set the dram voltage to 1.65 in manual? I can do 1.64 and lower and 1.66 and higher, but when i type 1.65 it makes it 1.66 automatically?

 

[MIAHALLEN]

It'll be fine at 1.66V

I agree set your ram timing down. During my testing I just set the multiplier at x8 xmp disabled while to get different OCs and retested once I put the memory at the highest supported speed. I currently have the corsair ddr3 2000 memory at uncore x20, multiplier x10 and at 1.64.

Ok i ditched the X.M.P. and went with manual

Everything looks great to me... Temps are pretty much where they need to be, althought i thought the cooler was a little better @ 3.5GHz.

 

[exedotbat]

I played a game on steam after OCCT with no issues, decided to restart and after I signed into windows it froze and restarted. I started windows normally and error said BSOD. Any Thoughts? Fluke maybe?

 

[exedotbat]

Also in real temp I am just now noticing that my multiplier is jumping around is that normal?

Turn speedstep on. Its only supposed to go up on load, and down on idle but not fluctuating on idle.

QPI/DRAM Core Voltage 1.35 <-- change this to auto for now and see if that helps.

If that doesnt work, up the vcore a little - 1.26v

Yeah don't freak out unless it continues to do it regularly.

Now try lowering you VTT/QPI voltage to 1.25V and run the OCCT test again....I think 1.35 is a bit high for your settings, after that (if it passes) also try again with lower Vcore...like 1.2V

 

[exedotbat]

I turned on speedstep and still saw the fluctuating. Then I put everything back to auto / stock speeds and noticed it does the same thing so maybe that is normal and I never noticed it before. Tonight I will put the setting back and lower the QPI/DRAM core voltage. Is there a way to see what this usually is at stock speeds?

Also can someone explain the Vcore vs CPU usage in the occt vcore chart.
