Cheers for the replies. I'll report back

You can probably get by with 4.5 ghz, 1.25V at full load and all power saving functions left on. That should be something to aim for. You may need more like 1.3v which is fine as well. I also think you don't need to disable turbo just leave that all on auto and just change the multi to 45x.

Thanks, I will disable turbo. but, unfortunately I couldn't find DVID - I searched my BIOS extensively and for the life of me I cannot find the option to eliminate vdroop.

Would the LLC setting be useful?

LLC is what controls vDroop. It's just that some motherboard manufacturers call it "vDroop Control" instead.

Dynamic VID (DVID) isn't eliminating Vdroop it is merely what Offset might be called on some boards. I can't find any info on how to do Offset with that board.

Load Line Calibration (LLC) is used to prevent VDroop from destabilizing an overclock as it adds additional voltage when the processor switches from idle to load. However Vdroop is an intentional design by Intel, it is a momentary drop in voltage when going from idle to load. I think it is intended to preserve hardware life.

LLC is useful for stabilizing some overclocks but I don't personally like to use it for 24/7 overclock settings because I am superstitious about it potentially frequently overvolting the processor in small amounts, instead I have always run more offset and gone with the best I can achieve purely with offset, however for benchmarking I have used LLC with good results for higher stable clocks.

Like all voltage controls you want to go with the minimum you need to achieve stability at the clock you want so you would test various LLC settings and go with whatever adds the least amount of voltage and still gives you stability.

The voltage is SUPPOSED to drop under load. This is normal, expected behavior on both AMD and Intel platforms. smile.gif Vario is right.

Generally, you want the LLC to eliminate vDroop totally, so that the voltage you enter is the real voltage the chip gets under load. On my board, this works perfectly with LLC at the default setting. Under load, my voltage as reported by AIDA64 is the same as what I set it in the BIOS.

But this is too optimistic a setup for an older board. You want to play with the settings until the voltage is as close, or slightly under what you set it in the BIOS. For example, with my FX-8350 and Crosshair V Formula, when I set it to 1.55v it does 1.52v under load with LLC on "high". However, if I set LLC to maximum, it will give it something crazy like 1.6v under load. This just adds heat, destabilizes things and can be dangerous. So I recommend you set your LLC to either standard or high, if you can find it.

I've always just let the voltage value I set in the bios be slightly less than the voltage I see in HW Monitor and been perfectly fine with it. I am running 4.5Ghz with Offset Mode +.01v right now which results in a VID value of 1.261 and the resulting Vcore value of 1.260 when I run Prime 95, at idle I have 0.856 VID and an actual Vcore of 0.672V. I am not running any LLC setting beyond whatever the Default for Gigabyte is (which I think is None). This is my 24/7 stable OC.

Again VID is what the Processor asks the motherboard for, but it is different from the Vcore that is actually supplied in response.

I think its worth your time to figure out how to do the Offset on that board because it will keep your hardware running cooler and your system will last longer but I am not sure what it is called on that board. If you have a manual take a look and see if there is any mention of either Offset or Dynamic VID or Dynamic Vcore

Offset on the board, was that directed at me? I do have the manual, I can look it up. Sorry, not sure if you're talking to me or the OP.

Jealous of your low voltage anyhow. I have an absolutely awful 4770k. It takes 1.47v to be stable under load @ 4.5 and runs in the high 80s/low 90s during x264. In most games, even recent ones like Witcher 3 in Eyefinity, the hottest I've seen it get is around 60C though. I love my h100i and SP120s. This 4770k also absolutely refuses to do anything higher than 4.5Ghz.

I have all power settings enabled and I use my computer for web browsing more than anything else, though. It is also my file server for Chromecast/PS3 streaming media. The majority of the time it's downclocked to 800mhz and when I check the voltage in CPU-Z, it's often like 0.016v or 0.210v. It's held up this way since May 2014 so I don't think I have much to worry about. I can also afford to replace it. thumb.gif

Was directed at OP apologies for lack of clarification.

This is a binned 3770K. IIRC I can run it up to 4.8 GHz @ 1.4V on air. Prior owner achieved 1.173v @ 4.5GHz and 1.280v @ 4.7GHz but he was running a massive radiator. I am running a Phanteks PH-TC12DX, which is pretty mid range even with a San Ace fan on it.

The 4.5GHz@1.260 gets me to about 85*C max in Prime95 Blend.



edit: put in prior owner's voltages, pretty beast chip.

Hey guys,

I' haven't read your latest posts yet as I'm quite stessed.

:Lately my computer has been powering off randomly... I reset my CMOS, I installed a fresh copy of win 10 on a new SSD, I've tried disconnecting all non-essential hardware and it's still persisting.

Heating is definitely not an issue. There's no BSOD or error message of me to investigate and event viewer in windows is of no help either.

Most likely a PSU issue (it is 3 yrs old) - II removed one stick of ram, problem persisted, then exchanged it for my other stick of ram (2x 8gb) and still the same issue.

These problems only started recently when I manually modified my ram timings/frequency (it was 1333 until I got it going at 2133 + the timings were completely off)
I am just wondering if there's any diagnostic tools I can download that may help ?>

Whoa, you overclocked your memory from 1333 to 2133? That's why it's turning off on you. Your PSU is way too high in quality and still way too young to be the problem. The kind of PSU you have there should last you several more years.

 

Is your memory even designed for 2133 MHz?

It's a computer!

Nooo. I did not OC my memory.

Sorry, let me clarify:

My ram is 2133mhz - but for whatever reason my MB was running it at only 1333mhz (and incorrec clock timings) - I simply corrected that in the bios.

Do you think it's a MB fault?

I guess it's a matter of trial and error. When I get a chance, I'll hook up my brother's 650 watt PSU (it's a good brand, I forget the name atm) and see how that goes.
