Is it good overclocking numbers ? (intel i7-2700k) [CLOSED]

post #1 of 35
Thread Starter 
I finally succeed overclocking my computer at 4.78 GHz. Here is the result. Give me some feedback (my actual concern is my vCore Voltage).

Settings:

Multiplier : x48
Base Host Frequency : 100 (default)
CPU Voltage mode : Offset mode
CPU Offset mode : + 0.350 v

Temperature:
Ambient : 22'C



# My air cooling setup > (Click to show)

I have the Phanteks PH-TC14PE cpu air cooler. You can see my bottom-(near psu) intake and my top exhaust. My two 140mm Phantek fans are also pushing air outside, as for the rear Corsair AF140 fan. I also have the two 120mm intake fans (front panel) and the 200mm side panel fan.

# My computer spec> (Click to show)

Case : Corsair Carbide 500R
Powersupply : Cooler Master GX 750W (12V@60A)
Motherboard : Intel boxDZ68BC
Processor : Intel i7-2700k Sandy Bridge (3.5 GHz)
Memory : Kingston HyperX DDR3 16GB (2x8GB) CL10 (XMP 1600mhz)
Solide State Drive : Intel 520 Series 240GB
Hard drive : 2x Western Digital Caviar Green 2 TB
Video Card : 1x Evga GeForce GTX 670 FTW 4GB
Windows : Windows 7 64-bit Professional French rolleyes.gif

My actual questions :

1 : #
About my CPU vCore, is it too high for a stable daily usage, 25% of light gaming ?

..- (heard that optimally, I should be at less than 1.325 max ! I am at 1.344 idle, 1.360 max. I should try putting down my +0.3V offset to like 0.25 or 0.2, but I think I will have to down the multi too..)

What are you thinking about it ?

I have a 2500K that I run at the same speed as yours 24/7, except I keep my Vcore at 1.40 V for daily use. Above 1.45V is where damage starts to happens for everyday use.

Fine, then i guess i could be OK if i left everything as it is. Still, i will try to optimize my vCore a bit. Thank for you post !

edit : Any suggestions about LL and Drop % ? Some ppl are saying that setting a manual vCore instead of using an offset is better in the way that we do not have do undervolt things, etc. I dont know really ..

4.8GHz at 1.36V is very good, as long as it's stable of course thumb.gif
I have a pretty decent 2500K and I need 1.38V to be stable at 4.8GHz.

I wish I had your chip haha, for stability I had to set vCore @ 1.365 with 4.5GHz on my 2600k, the funny thing is that it boosts its vCore to 1.42v @ full load and that's because of the vdroop stuff (I have LLC @ level 5 also that's why) so it's actually set @ 1.42 for a stable 4.5GHz overclock, the maximum allowed voltage for the Sandy Bridge i7 is 1.52v, but I wouldn't go beyond 1.42v myself.

My 2600k is running @ 4.7 GHz fully stable on the same voltage, so yours seems to be good enough.

I've heard of damage at 1.4V from people running their system at 100% load 24/7. 1.45V should be the absolute max for everyday use on Sandy bridge.

That is one impressive chip. Mine takes 1.33V to get to 4.5GHz.

Not true,1.40v in general is not bad for Sandy Bridge, maybe it is bad @ 1.45v+ yeah. I've been using my 2600k @ 1.42v for 1.5 years now and 24/7, and usually my cpu is @ full load due to video encoding, heavy gaming and etc.. I've had no problems at all nor do I think that my CPU is going to die, at least not soon smile.gif

I can't seem to find the post now, but there was a guy running his at 1.408V for seven months straight at 100% load, and it degreded to the point of needing 1.44V for the same frequency.

I would expect that it varies from CPU to CPU, though.

Two new screenshots. At my parents' home, my pc is doing better, temperature talking. I only did about 15min of blend test on Prime95 >> 65 69 69 72 ' C . @ cpu vcore at 1.384 volts. Gotta optimize that th ( voltage).

Question, why in my bios I set 100 bclk but here this is showing 99.77 !?. redface.gif
