CPU is rock solid at 4.5ghz. No 9c, no 101, not 124, nothing.

That's why you aggressively test VRIN at 4.5, where you don't have three different bluescreens kicking you for unknown reasons at what could be completely random times, and you can say for example:

x264 fails on average once every X minutes with 1.25/1.7

y minutes for 1.25/1.8

z minutes for 1.25/1.9 etc

and then poke between the two best results, and try it with 1.24vcore, etc


VRIN can be tricky at high OC, like overclocking haswell past 1.35vcore can be really damn hard. I guess the only thing i can say is get a few profiles nice and tight, below what you want, tight and solid and then kick things up, be overly aggressive on volts (vcore, vrin), try multiple VRIN values (step in 100mhz's if you have to, though that type of ocing can take weeks) and then get everything stable, then fall back what you can. If you're not a masochist benchmarker you'll hate going over 1.3vcore or so on these cpu's from what i've seen.. (because of the complicated stuff with vrin, ring etc that comes with it) hopefully there are a few keys that are more worked out soon for stability

My testing is showing higher stability with higher Vrin and higher Vcore.

I just tried 2.05 VCCIN, 1.41v Vcore up from 1.37. +0.135v offsets for SA/Io voltages vs +0.1.

 

Now it takes so long to bsod at x264 I'm actually too lazy to test. Last time took 26 minutes to bsod with 101. This time just passed stage 2 three times in a row. It's hard to make adjustments on the fly like this because each settings I do 5 tests, that's like 2 hours or more sitting here babysitting my PC.

A little help guys.

I moved off 3770K, but the last CPU i really invested time into, is my current 2500K, and i know that on water it should stay below 1.4volts to retain a good life span.

How are these figures with the 4770K? I have searched, but yet to find what the stock Vcore is for this CPU, and also been looking for the magic, do no step over line, for daily use.

My 4770K will be watercooled, with custom loop.

If anyone could hand me these details i'd be very happy . I like to plan ahead, and so far i still need to build the rig up from the ground, but have some modding left to do on the case thumb.gif

If more info is needed setup is:

Asus Maximus VI Formula
4770K
Vengeance 1866Mh 2x4gb
Corsair AX750
2x 7970Ghz 6Gb (Sapphire)
Few SSD's and one HDD (not important)

Loop:
Highflow 12mm fittings all around.
Laing D5
240mm XSPC (60mm thick) push/pull with GT-AP15
360mm Slim with pull GT-AP15
EK Supreme CPU block (copper w/ acylic)
2X EK VGA supremacy blocks
Primochill advanced LRT tubes.

The safe range of voltage and temperatures have already been listed in the guide.

I'm not quite sure why stock voltage is useful though.

I want to contribute my experiences with X264 Benchmark.
First my 4,5 settings
1,22 vcore i can do Handbrake, cinebench, Games, no crashes at all for 6 weeks now.
1,245 vcore for Prime avx 27.9 1344K test
1,81 Vrin seems to be optimal, lower crashes 124, higher crashes 124. llc high so far.
1,13 for x39 Vring seems to be the best, lower I think I also got 124. Higher would be unstable as well.

Tested 4,5 Ghz x264 with 1,22 vcore, would crash in first run shortly after beginning the second test. Error 101 tested this repeatedly.
Raised vcore then to 1.24, x 264 would pass 2 runs with two tests each. Stopped then, had no more time.

Yesterday tested x264 at multi x46 but no success.
Vcore 1,255-1,3
Vrin 1,85-89 1,87 seems best. llc high or standard makes no difference tested with 1,84-1.89.
Vring x39 1,13-1,15 1,135 seems best
SA IOA/D +0,0 would crash + 02,03,02 lasted longer + 05,06, 05 no difference as 02,03,02
It will crash first run in second test. And System will frreze and then I have to reset. Error always 101...

The weird thing is at x45, by just raising vcore 0.02 helped to eliminate 101 and System passed two runs two tests.
X46 even raising + 0.045 vcore did not help. System would crash first test second run. System freezed and Error always 101.

So my Error with x46 is always 101 now. Needs further testing. mad.gif
If someone has an Idea to stabilize x264 benchmark with x46 enlighten me..smile.gif

I'm still under impression it's mostly the voltage wall.

Stock volt, is to know my starting point, and i like to take auto volt off, and some motherboards start with lower volt then stock volt, for under volting smile.gif

I had missed the fold out parts of the OP.

But i can see that i'll be looking to max out at about 1.35v smile.gif

It seems to be. Well the chip is not delid yet and at those clocks the max I've hit with stress test is 84C (That was a spike on one of the core). I guess if I delid it temps should drop down to 65C ?

Should be Input Voltage

Setting uncore ratio to 39 makes things a lot easier ... and does not affect performance that much.

you may want to try Prime95 Custom FFT in place with 448K / 800K to check if input voltage fits.

when you get through 448K but have BSOD 0124 with 800K you can try to increase or decrease cache voltage

run 512K/576K to check cache voltage and 720K for system agent.

i spend a whole afternoon getting my 4770K stable with all Ks @ 4.5 with 1.19 VCore

each selective K should at least pass 30 minutes.

Hey, can you use HWinfo next time? I'll accept this as picture verification though.

Batch number can be checked by either the label printed onto the CPU itself, or the box which the CPU came with. It's near their barcode on the box.

 

Sorry, Box was long gone (Dog got hold of it while I was putting the machine together.) I will try get the numbers once I get time to delid the chip. I was using HWInfo, but the reading were the same. I just wanted to run AIDA64 stress test while taking the screenshot to show the 1.296v
