post #7942 of 11364
I've been working on this for a little while and although I'm sure I could get lower voltages or higher clocks with more tweaking, this is my first stable overclock and I'm too nervous to mess around with it much more... Also I wasn't sure where to submit this but since nothing else was given (that I saw) I figured it's just in this thread.

Username: mvhcmaniac
CPU Model: i5 6600K
Base Clock: 100 MHz
Core Multiplier: 46
Core Frequency: 4600 MHz
Cache Frequency: 4400 MHz

Vcore in UEFI: 1.400 v
Vcore: 1.432**
**Really, 1.424 and 1.440. It spent most of the time at 1.424 but would spike to 1.440 for seconds at a time. There were no readings between these two values.
FCLK: 1000MHz
Cooling Solution: Corsair H55, push/pull 120mm as intake
Stability Test: OCCT v4.4.2 (Is this okay? The download link sent me to this, not 4.4.1)

Batch Number: Vietnam X548B027
Ram Speed: 2666 MHz 15-18-18-35
Ram Voltage: 1.275v
Motherboard: ASUS Sabertooth Z170-S
LLC Setting: 6
Misc Comments: I actually had core voltage readings in three distinct steps, with no readings between. At idle, it was a constant 1.408. At 99-100% load, it was a constant 1.424 for most of the time, but occasionally it would jump to 1.440 for a period of time. Again, there were never readings between those values. Even changing the Vcore and LLC settings in BIOS I could not get any other readings.
I ran this for 3+ hours before but I tweaked some things, failed, then changed them back since then. All the settings should be the same but I ran it again just to be safe.


OCCT automatically saved the graphs from the run, so I'll put up the graphs of frequency, temp, Vcore and a screenshot of the UI while it was still running. If you want any of the other graphs, I can put them up, but I felt like 4 pics was enough clutter in the thread.

Here's a post from someone else running an i7-6700K with an air cooler. They tested with P95 SFFT, & saw 83C on the hottest core at 1.349VCore According to the spreadsheet on the first post, they're running an NH-U14S. I would expect your cooler to perform similar to that. Your actual temps at 1.2VCore do seem high to me.

Side note, it would be nice if average core temperature were listed in the results spreadsheet.

yeah its a little high.I was looking at the spreadsheet and I think i should be reaching 4.5ghz without reaching thermal limits(for me 80C)

Hey guys, not sure where to post this but figured someone here might have some insight.

I bought a new PC a few months ago with an i7 6700k, gigabyte gaming 7, 16GB ddr4 3200mhz ram and Antec EDGE 650w.
Recently I noticed in event viewer a lot of WHEA warning's popping up every minute (thousands per day)

this is the warning:
Description:
A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor APIC ID: 1

other than this error, I have had no problems with my PC. (no blue screens or anything, able to stress test + game with no issues)

I am running all voltages on auto and have set the CPU to 4.6ghz in BIOS. I've tried reverting to optimized defaults and still get the error.

I'm wondering if I should be worried about this even though it doesn't seem to be causing issues, could it be software related? I have a bunch of rainmeter gadgets to monitor CPU usage and temps, but turning it off still produced the errors.

I'm running a Noctua DH-15 as the cooler and my temps don't go over 65 during load.

Also tried memtest and Intel's processor diagnostic tool, both passed.

a machine check error is a "correctable" WHEA - either it's an unstable overclock, or if you are running at ALL STOCK settings, a failing component. Built-in error correction checks a proc call result vs it's checksum, if it does not match, it runs the proc call again... holding up the execution stack. This can mask instability and make an OC much less productive than expected. Auto voltage is not a good idea at 4.6. Set you voltage manually - control all voltage rails at 4.5 and above.
Do a clrcmos, not just load opt defaults. if it still shows up, try each stick of ram alone in the proper slot. if it is not the ram... you'll need to volt the cpu higher than stock (eg, it has degraded).

Another question, isn't the VID voltage CPU is requesting, so why would Vcore be higher if I'm using LLC3. I'm using stock frequency, with boost set to all cores instead of auto so it's 4 cores @ 3.9GHZ.
With LLC3 i'm getting 1.3V VID and 1.392Vcore in HWInfo64.

Thanks for the reply, I've gone ahead and reset the cmos and left everything at default. Now the only error that's showing is a memory error:
*edit* - another processor error showed up after a while

A corrected hardware error has occurred.

Component: Memory
Error Source: Corrected Machine Check

I wasn't able to test each stick of ram as I'd have to remove the noctua fans and seems a bit of a hassle. Is it safe to say the RAM is the culprit? They are - G.Skill Ripjaws V F4-3200C16D-16GVKB, which were on the motherboard QVL

I had my local store put together the PC so it should be under warranty, though I'm unsure if the error would qualify for a replacement.

You should do so! That's what warranties are for...

Pack it up, and take there, I'd be interested in what they say/do... biggrin.gif

Dumb question:
So for voltages do I take what HWInfo "Vcore" as actual volts or am I just at the mercy of bonk read outs?
trying to get stable at 4.9Ghz and I am already at 1.425 in bios but in HWInfo it's shoots up to 1.488 while running the X264 test in Realbench.
Also is 85c the absolute limit for temps?
