assuming VRIN even behaves the same on different chips.. seems to be similar at least. Nobody actually tested that ha

The main difference is that I'm at stable settings - whereas he isn't. So apprently, that CPU needs more volts, and actually isn't a 1.2v CPU....I do agree with the other point that is being mentioned - testing is needed to figure out what is going on.

What error code does the BSOD show when the PC crashes - that'll at least hint at what needs to be changed. Also, keep in mind that the core and ring aren't necessarily the only things that need to be adjusted in order to have a stable OC....

You have to re-check this one. Yes you will damage the chip with 1.5v on air.
Are you cooking on it or what? It is highly recommended that you check what temperature you are at in these circumstances.

When you have delidded CPU and watercooling, 1.5v vcore may shortly be ok for benchmarks etc. if temps are allright.
But 24/7 probably way too much.

Error code is 114 iirc.

I finally managed to run x264 without crashes, currently running XTU (almost 2 hours in), temps in the mid 70's. The settings I am now using are

Multi 46
Vcore 1.305
Vrin 1.9
Uncore 34
Uncore vring 1.15
Xmp off
LLC extreme.

So far so good, it looks like AIDA64 is not stressing enough the CPU, I could run it with 1.245 vcore and 1.85 vrin for 4 hours.

Once I'm done with the test I will try for 47 multi. I don't want to go higher than 1.35 vcore. If I can stabilize 47 multi, great, if not, I'm more than happy with 46 biggrin.gif

The only drawback with x264 is it's advisable to keep an eye on it. It'll have a percentage counter for each pass so knowing when (if) it crashes is key to letting you know what effect your adjustments are making.

I have x264_Benchmark_HD_v5.0.1 (with AviSynth 2.5.8) and can only run it in 32 bit mode (In Windows 8).
If I try 64 bit mode, the benchmark runs "AviSynth64 Installer v3" with error "Access is denied."

Is there something special that I have to do, to get x64 running?

Yes, https://code.google.com/p/avisynth64/wiki/InstallationInstructions

It's 2 dll files you have to put in the system32 directory

Uff. I'm not sure that I will have the time to try that procedure. Is 64bit version much faster then 32bit? (I get around 16.20 fps with 32 bit in pass 2 on my 4670K @ 4500 core, 4300 cache). Which version do you guys use?
post #3858 of 19539
Got this baby (4670k) today. Running it on a GA-Z87X-OC. Did 4.5Ghz. Passed 10 runs of Intel IBT.

CPU freq is 4.5ghz and uncore is 4.4ghz.

Ran Cinebench, Single core - 1.97, multicore - 7.54
Load temp IBT - 87c max, CB - 67c max

This was achieved using
vcore - 1.25v
vrin - 1.9v
v ring bus - 1.2v
LCC - Extreme
Phase - Extreme

Want to shave off 5c atleast. Time to tweak voltages by dialing back 10mv?

I use the 64bit. I get 72.9 on 1 pass and 17,3 on 2 pass. With 4670k @ 4500/3900

So, 64 bit squeezes a couple of frames more out of it. Thanks, I will try it ...
