My results so far:

Username: brutus090
CPU Model: 4770k
Core Multiplier: x44
CPU VID: 1.210
Vcore: 1.216
Uncore Multiplier: 39
Uncore Voltage: Auto (1.084 default)
Cooling Solution: Phanteks tc14pe
Stability Test: Aida64 (12 hours), x264 (without looping script, standard 8 pass run, max temp 71*c), Intel XTU Benchmark (977 marks, max temp 73*c), IBT High x10 (max temp 90*c)
Batch Number: *will update when I reseat my heatsink soon*
Ram Speed: 1600 @ 9-9-9-27
Input Voltage: Auto (1.696 default)
Motherboard: Asus Maximus VI Hero

Despite the fairly extensive stress testing I've done so far (I still plan to do x264 for 20 loops for assurance), the system seems to be fairly unstable in Far Cry 3, crashing after anywhere from 10 minutes to 2 hours. I haven't had time for too many other games so I haven't checked out much else, but does anyone else have experience with FC3 causing instability? Or perhaps it just needs a for move volts?

Do you have SLI? Ever since the latest FC3 patch (I'm using 331.82 Nvidia drivers) I can no longer play FC3 with SLI enabled, my computer will freeze / BSOD anywhere from a few minutes to 30 minutes. With SLI disabled I have no problems.

I agree I wish it wasn't so, but anything p[ast 4.3 bsods. Yes i will test tonight and write down bsod codes wont even boot to windows. It doesn't make much sense to me either but it is whats happening.

Have you tried out the newest driver?

Like I said I went to 1.18 instead of like 1.15, is this stupid?

1.180v is not bad for 4.2. It took me 1.198v to be 100% stable @ 4.2(38 uncore). 4.3 took a large leap to 1.265v to be 100% stable (38 uncore).

What's cooler are you using? As long as temps stay below 95*C your fine. Prime95 and Intel Burn Test will always make your CPU run hotter than XTU and other benches. If your on adaptive voltage or offset, you'll see that your temps spike in those benches a lot because your CPU is calling for extra voltage. You might see that its drawing .010v or more and spiking temps 5-10*C higher.

Have you tried touching Vring/Cache voltage to help stabilize the ram/uncore? Or +.015v to system agent/IO analog/IO digital to try to see if its the controller?

GL.

I'm going to put 10 bucks on the fact that Jedson needs +0.15 SA/IO and a higher VRIN for 4.3 giggles to stabilize.

srs paypal bet.

Who's keen?
post #7966 of 19539
Jokes on you. I use IO analog and Digital on auto and SYSTEM AGENT at +0.10. My ram is being down clocked what use would that do other than for the IMC. I'm having issues upping GHz on chip because it sucks, not overclocking my ram. 4.4 ghz It wont boot to windows. Bsods! And that is at raising vcore from 1.18 to 1.2. yet 1.18 @ 4.2 Aidia 64 24 hours is stable set to 512 ram for testing. The problem we were discussing is I had memtest86+ fail because the 1866 was to aggressive for the 4.2 at 1.18. It passes at 1600 MHz though. 1866 for some reason wont become stable even at 4.2. now ram aside even at 1333 I cant go past 4.3.

Jedson, forget 4.4 right now. Let's deal with 4.3. Why are we skipping a multiplier? The ram is at stock, let's just set it and forget it. It's irrelevent right now. Let's see what we can hash out with the core overclock. 
 

Ram to stock, let's see what combination of Vcore and Vrin is required for stability.

I might have missed it but what is your vrin?
post #7969 of 19539
I believe I manually set it to 1.8 because I'm not doing anything to aggressive I manually set it to stock which on auto shows 1.8. Also to be clear I have been working with SIN and NY chip is terrible to be honest. I got some of the launch beaches that just suck. I've left uncore 35 and haven't touched ring voltage because I'm not reading that yet.

(Once as in, stopped testing after bsod and moved onto next result). Your voltage is very fine, so I wouldn't expect stability to change that much. 


For example, if we guess that higher Vcore is actually decreasing your stability, it makes no sense to pass 10, pass 10, pass 4, pass 5. It's like your stability didn't change too much from 1.18 to 1.185, then stability cuts in half from 1.185 to 1.19 and then gets better again. I think it makes more sense if this is statistical noise. But either way it's a mind-bender.

One other explaination would be that your Vrin is very, very low, so that when you upped the voltage, the gap between vrin and Vcore just got bigger and bigger, leading to more instability. That's sort of a long shot. I mean, even if you didn't pay attention to Vrin at all, a Vrin problem @ less than 1.2v? Unheard of.

I ran IBT many times on every settings.
4.2 - Multiple IBT at the start since i had no clue about x264 testing, then thought of upping the clock before that ran x264 bench as told by cyro.Everything i ran with that clock gave me rock solid stability, i mean BF4/3 and every other things worked like a charm.

Went to 4.3 @1.185, got BSOD on IBT high levels but passed 10 x264 loops.Tested again with IBT/x264 gave me same thing....upped Vcore to 1.190 again same thing but x264 somehow stopped while displaying "access denied " after 4th loop.So testing again gave me BSOD on IBT high.
Then increased Vcore to 1.195 which gave me successful IBT high but x264 "access denied " on 6th loop.I switch off the monitor every time i do x264 testing as it takes long time and wondering if this might cause " access denied " by moving-clicking mouse/keyboard keys.


Vrin - 1.740V Stock
Vring - 1.050V Stock
PCH core - 1.090V Stock
PCH- id - 1.5V Stock
Uncore - 35x
OS - Win 8.1 ( latest with all updates )

Going to up the Uncore to 38-40 level and see if X264 / IBT passes or not.
Does any failed X264 testing gives "access denied " in the shell window ?
