Overclocking Intel i7 3770 3.4Ghz (non-K version) with stock HSF - is it possible?

[dayglo98]

I dont know about Ivy Bridge, but for Sandy Bridge (I have a i5-2500k) you can overclock plenty before you need to invest in an aftermarket cooler.

Hrm... I ran some kind of OC Tuner or similar from BIOS and then it displayed 3.54Ghz instead of 3.4Ghz and the Turbo mode is at 4.1Ghz (checked via CPU-Z). I guess it is a small overclock. I just have no idea how I got it. I did not change multipliers manually (I could not find an option to do so), but then OC Tuner or whatever it was called restarted my PC 2 times without a beep and gave me multiplier 41! I guess this is better than nothing.

My CPU-Z shows my clock speed at 1600Mhz when PC is idle, and 4100Mhz under load. Is that normal? Should it not be 3400Mhz idle? I guess it is that SpeedStep technology. I just want to make sure I run everything at highest performance/power I can.

Witcher 2 runs butter smooth with ubersampling on!

LOLWUT?

Do you have 680 SLI or something?

No, I don't. It doesn't run as smooth as without ubersampling, but it definitely does 30+ FPS.

Anyway, back to my humble 4.1Ghz overclock... comments on my inquiries?

Nope that is correct. There is no point in disabling speedstep, it does not give lower performance it only saves power :)

Great! So, I did overclock to 4.1Ghz from 3.9Ghz, right? I know it means little, but it feels nice...

Oh wow! I ran OC Tuner again and got 4.250Ghz and RAM slightly overclocked. I managed to decrease 2T to 1T. However, my BCLK was raised to 103. So far, the temperature is fine, and the overclock is stable. So much for non-K!

I'm pretty sure you could get 4.6ghz without much fuss from a K version.

I'm a newbie to overclocking today's technologies, but back in A64 3000+ days I was deep into overclocking, cooling, etc. and did quite well.

I recently ordered the non-K version of Intel i7 3770 3.4Ghz @ 3.9Ghz Turbo with stock cooling. I know it is not very overclockable, but it appears there are some possibilities. My motherboard is ASUS Sabertooth Z77 and RAM is 2x4Gb Corsair Vengeance 2133Mhz (2T). I inquired about overclocking in a different thread (off topic) and received the following reply:

"Actually Non-K CPU's should have a few bins over their maximum turbo mode, so you can get it to 4.3ghz. A 3770k should have up to 63x multiplier but a 3770 non-k should have 43x or 44x. As this is around the maximum overclock for Ivy Bridge on air for most people you're not actually that bad off. If you can get it going you'll gain about 400hmz over top turbo speed.

But you're using an Asus board as it'll turbo all cores to 3.9 at stock anyway, you were never really going to gain 25%, you've only really capped your overclock potential on air by maybe 200 or 300mhz."

1. I used Google and found out that using BCLK an overclock can still be made, but it will affect the whole system, including SATA and can create write/read corruption/errors. Is that true?

2. I would appreciate if someone could explain this whole thing to me and let me know how to squeeze everything out of my non-K CPU. I know Ivy Bridge CPUs run hot and I have stock cooling, so possibilities will definitely be limited.

3. Also, since I would need to set a divider to utilize 2133Mhz of my 2T RAM, would raising BCLK affect that as well?

4. Should I somehow disable Intel SpeedStep to make my CPU run at maximum speed at all times?

Thank you in advance!

Hi, I have the same processor i7 3770 non k,but I have a gigabyte board, there was an application EASYTUNE ,This application makes the process automated overclock, it runs prefect no bug or anything
