I'll have to try that at some point. It's inconvenient, since i use iGPU for my secondary monitor. Good point though.

P.S.: What did you mean about disabling PCI-E bus? Don't you need that on IVB processors for discrete graphics cards?

Do you need Lucid Virtu to use the iGPU for the second monitor?

Help on overclocking other hardware in my system would be nice as well.

My system specs are as follows:

Intel core i7 3770 3.4GHz
Asrock Z77 Extreme4
Gigabyte N660OC-2GD Geforce GTX 660 2GB
Patriot Viper 1866MHz 8GB RAM

Thanks!

While my postings at overclock.net are mostly focused on my 3770K (5.3+ Ghz per5 Ghz table in this site), I 'warmed up' with one of two 3770 non-Ks that are in a virtual machine...Top speed I reached was 4.560 Ghz, using the max for that chip 43 multiplier and a BCLK of 106 (per pic below)...voltage settings where just about 1.3v, but with 'extreme' DIGI settings and and PLL of 1.775, max v core came to 1.344v (safe territory) though 100% load v was lower. This was done with a 'basic' Asus P8Z77-V LK board and Thermaltake Water 2.0 Extreme closed-loop cooler...

...there was a bit more speed to be had has the BCLK was not maxed yet, but by that time, I started to oc the 3770K...the non-K is a very nice chip you will have a lot of fun with !!!

I was using it until it started causing stuttering with my current GPU, so I uninstalled. Still unsure if I want to continue using it or not using it. Need to tinker with a Kill-a-Watt for fun. I'm actually just using my second monitor plugged into the iGPU for the reason of better chances of displaying something when I reinstall drivers or troubleshoot (my primary monitor is one of the Korean IPS panels and can only work through a discrete graphics card... but is also slow to display things, and actually turns off when I uninstall / clean drivers).
----
I wish my board had PLL voltage control =/ That's the price I pay for going with this mITX motherboard.

I'm sorry I don't quite get it, so your secondary monitor is plugged in but not running, and only for backup?

No no, it's running. 2 monitors, one connected to discrete graphics, one connected to the motherboard (HD 4000). Both on, extended desktop mode.

P.S.: glad I posted here -- learn new things every day

Sounds like the non K version isn't so restricted after all then. 4.5GHz sounds great!

I only meant disabling the IGP, I meant that the IGP and PCIE bus are the two main reasons baseclock OCing doesn't go well with 1155, By eliminating one you have better with the other.

so IGP + PCIE bus = problems for baseclocking

removing IGP leaving only PCIE BUS = better chance with silicon lottery

i've been tinkering with my laptop further can get to 112mhz baseclock but it gets exceptionally unstable, The new bios doesn't like anything above 108 it simply locks up and requires a reset.

Edit edit: Your ram may also limit you, Because when you OC Baseclock it oc's ram aswell as the dividers are pushed as they are based off of baseclock, So if you lower it a notch from 2133 to 2000 you should be able to push slightly,

My ram is at 1866, so lower to 1600?

Thank you for the info ElevenEleven .

Yes, you do learn new things everyday.

In theory it raises the amount of data communicated back and fourth per second, In reality it does not.

At least nothing really noticeable. I think most of the extra performance with higher bclk comes from the higher cpu & memory clocks gained.

...as we say in Canada: "Yup, most definitely"

...per my post, I worked with several 3770s (K and non-K)...the VERY LEAST each one of them reached is 4.5Ghz...you have a fun time ahead with your new system based on the 3770 non-k

Was pretty happy with this - might try another notch or 2 tomorrow.

Beautiful! This is exactly what I want for the I7-4770 (and maybe more if bclk is available), so that VT-d and TSX are available, vs the K version.

I've observed this as well, although I don't really understand why. It's possible for all cores to run at max multi, except when the processor load is high, it throttles down two multis. It seems like it's the opposite of what should happen.
