I decided to mess with the BCLK strap as a last ditch effort. Currently doing 4.6 @ 1.320v with 1.25 BCLK strap and x37 multi IBT 10 standard stable. I'll continue testing.

Who is up for a x264 test run ? Just for 4770's (with HT on).
Cyro999 ?!?, since you know how to modify the batch...

I'm in the process of repacking the test (with a few modifications and an 64bit version only) and i want to know if i should make HT / non-HT batches separately.
All you have to do is add '--threads 8' after '--crf 18' to look like this: ...x264-%bit2run% --quiet --preset slower --crf 18 --threads 8 --rc-lookahead 80..., and run one loop with it and one without it (the default batch) while logging with HWiNFO.
Then compare the two logs and see if it makes a significant difference (FPS, load and temperature wise).

This setting tells x264.exe to use 8 threads vs the default setting '0' which means 1.5 of the available cores which means 12 threads for 4770's. And i suspect this might add some leasure time on the stress since this test has no avisynth scripts like deinterlacing, adjusting brightness, removing noise, fading etc..

Thanks for the info about MSI G45 Gaming mobo and Adaptive voltages, much appreciated.

Been running 4.4ghz Core 4.1 Ring, both with Adaptive voltages (Vcore 1.19, Vring 1.14), will surely be switching back to Manual settings. I read through your instructions about power saving, but can you explain how did you get the Voltages to drop on idle with both Volts on manual?

Sure, gimme a few hours (birthday and new nvidia driver)

Cstates enabled. c1,c3,c6 will lower at idle. c7, c7s if u have the right psu to drop that low. I personally dont use manual anymore, i think adaptive scales better up and down with the multipliers better than manual. i only play bf4 so it never spikes super high volts for me when running adaptive.

Please add my results to your chart smile.gif

Sadly, its just 4,4Ghz. :/
I don't want to use more voltage than 1.3 and I'm really on the limit here with my CPU and UNCORE. Have been stable @ 4,6 with an older Prime95, but with the new Version and small FFT, i had to use x44.

this is my latest and greatest updated. mine scales as follows:

1.220-43x
1.270-44x
1.320-45x
1.370-46x
1.420-47x

i saw no difference between 47x and 43x for playing bf4. except temps...

Greetings, All!

Here is my Haswell experience thus far:

CPU Model: 4670k - sold/replaced with 4770k
Core Multiplier: 44
CPU VID: 1.3-ish
Motherboard: Z87-G65 [bios1.8]

CPU Model: 4770k - replaced with a new 4770k, after failed delid
Batch - L318 Malay
Core Multiplier: 44
Ring Multiplier:40
CPU Vcore: 1.34
Ring Voltage 1.20
VRIN: 1.95
Motherboard: Z87-G65 [bios1.9]

The latest 4770k seems to be much better than my 2 previous chips, although it is still nothing crazy.
So far I have tested the settings below and it seems stable (p95, Small FFTs 1 hour). I need to play around with it some more and fine tune it.

I am also using an older version of p95 so I need to update and retest.

Core Multiplier: 39
Vcore: Auto/ (HWINFO 1.127)
Uncore Multiplier: Auto
Uncore Voltage: Auto
Cooling Solution: Custom Loop
Stability Test: p95 Small FFTs 1 hour
Batch Number: 3333C Costa Rica - above average results on HWbot. I was lucky my local Microcenter let me pick through their stock
Ram Speed: 1866 Dominator GT 2x4GB
Ram Voltage: 1.504V
Input Voltage: Stock (HWinfo 1.776)
LLC Setting: Auto
Motherboard: Z87-G45 [bios1.9]
System Agent: Auto
AIO: Auto
DIO: Auto
Nondelidded

Core Multiplier: 44
Vcore: 1.185
Uncore Multiplier: 35
Uncore Voltage: Auto
Ram Voltage: 1.504V
Input Voltage: 1.845
LLC Setting: Auto
System Agent: Auto
AIO: Auto
DIO: Auto

Core Multiplier: 45
Vcore: 1.240
Uncore Multiplier: 35
Uncore Voltage: Auto
Ram Voltage: 1.504V
Input Voltage: 1.875
LLC Setting: Auto
System Agent: Auto
AIO: Auto
DIO: Auto

It took the chip 1.3Vcore/1.95VRIN to get into windows and be able to browse around at 4.6 ( it was getting late and I was pretty tired so I didn't test much). I will stabilize 4.4 an 4.5 before I attempt to go at 4.6 and above. Temps and voltage are acceptable at 4.5 (much more so than my previous 4770k) so I am pretty happy. again these are rather "dirty overclocks", so I will clean up, retest, take screenshots and update.

btw, should I disable C-States while I stress test with IBT? Different opinions about the C-States and OC stress testing floating around the internets.
