I7 930 Overclocking to 3.8ghz?

Hey guys, I am currently overclocking my I7 930 and I really want to get to 3.8ghz, however my temps are a tad up there, and I'm wondering if it has to do with my heat sink or if the voltages are too high, or the case is a tad small as I do have a midtower NZXT Hades case.

If I do make it to 3.8ghz, how much more heat would the processor put out?

Specs:

I7 930 @ 3.66ghz
XMS3 Corsair 1600mhz
Asus P6T-SE Motherboard
GTX 460 728MB
NZXT Hades Case
Coolermaster V6GT Heatsink

Here is what it is at currently:

Speed: 3.66 Ghz (at x20)
Bsclk: 183
CPU Voltage: 1.275V
QPI: 1.275V
DRAM: 1.60V
RAM @ 1463 mhz
My temps:

Idle: 42/41/42/41
Full Load: 79/77/76/75

Any tips or advice is well appreciated. Thanks!

that is a good heatsink but your temps seem a little high for your overclock. have you tried lowering voltages to see how low you can get while stable? I am using not much more voltage and I am running at 4.3ghz

I think you are right about the voltage being a bit high, I increased Bsclk to 190 and reached 3.8ghz. Currently doing prime95 and the temperatures have more or less stayed the same.

my i7-920 is running at 3.7 Ghz with temps between 72 and 70, considerably lower. Idle is bewtween 46 and 43, which is higer and CPU Voltage is 1.329V, which is alot higher. :bounce: 

So, yes, I would say you have a problem with your cooling.

My case is a cooler master scout, and my cooler is a Thermalright Ultra Extreme 120. I have two fans out on the left and top of my heatsink, and one pushing through from the bottom to the top. The TIM I am using is IC Diamond 24 carat.

Those temps are like what I had when I installed a Cooler Master Hyper 212+. The thought the V6 was bigger than that.

So I just went ahead and put up my bsclk to 200 and decreased the CPU voltage to 1.25 and QPI/DRAM to 1.25.
Now the processor is at 4ghz and I'm currently going through prime95 again and still, I am at 79/78/76/75C for maximums. It doesn't seem to be going up. Are these temperatures safe?

Yea, you'll be fine.

The danger point for i7s is in the high 90s.

I agree about the danger point being in the high 90's. I suggest using an odd multi I find the odd multi's are more stable and require less voltage than the even ones. nice to see you got down to 1.25 that is good and temps are a tiny bit higher than expected but acceptable

Thanks for that tip! I decreased bsclck to 191, and increased multiplier to 21 and was able to hit 4.0ghz at 1.23V and QPI at 1.24V, temps are a little lower. All is well, thanks.
