Need OC help

Hi guys,

I recently received my AW15 R3 with 7820 HK + GTX 1070 g-sync a few days ago and need a bit of help with the OC settings. I've never done it, so it's my first time, but I've been reading around the forums regarding OCs settings but would like to make sure.

What settings should I be using in XTU in order to run it @ 3.9Ghz on all 4 cores with out any power limit throttling? And realistically, how much voltage off-set can I achieve?

Thanks!

 

First we need to know your thermal temperatures in all cores including the GPU temp. so that we know if you're safe to overclock. Download HWinfo64 (I prefer the portable version) to monitor the temps, and if you have intel XTU already installed run stress test for at least 15 minutes but keep monitoring the temps.

 

Interested in this as well.

I got the 7820HK to 5.1kGHZ stable on a MSI titan, but you need to mod the EC and BIOS in order to get those high numbers.

3.9ghz should be rather easy to do. You shouldn't up any voltages, just straight up up the multis for every core to 3.9ghz, it should work.

 

He's right, and for 3.9GHz you can actually undervolt the cores in order to keep the temps in check too if needed. 3.9 is easy for the 7820HK, even if you're unlucky in the silicon lottery...

I run 4.3GHz with a -150mV offset for example however there's a little issue I've noticed with nothing changing the V on mine whether the offset is like -45mV or -150 (average is 1.165V target) so it's probably just a -45mV offset still...

 

u still havent show us the proof mate!! gotta show those runs in a video or somethin

 

Did you buy a PC or transformer that can OC to 5100GHz on notebook, unless your using Quantum powered super laptop.

 

It really isn't that big of a deal. Most 7820HK's are just limited due to power management of the EC firmware.

Static voltage on 1.27V, multies up until 5.1ghz and there u go. It does depend on chip sometimes tho if you can get that high, also how high the core voltage has to be, I'd say depending on luck you can overclock until 4.9 - 5.2ghz. It's only an estimate tho.

Also most people who buy a 7820HK based system usually don't overclock it that high, since the performance in game is non existant.

 

So it was 5.1GHz. If you scroll back you can fix a typo, I actually mistook your CPU speed.

 

oh. I just realized hahahahaha. Yeah my bad :'D

 

Hi guys, thanks for the responses.

I did do a couple of tests before heading off to bed.

I ran two 10 mins CPU stress tests in XTU with a - 120 mV offset @ 3.9ghz & max temps that reached were between 82-83 C

I ran another 10 min stress test but with a -130 mV offset just to see how low I could go the results were the same.

But all 3 tests reported a random power throttling, which I have no idea why. Max watts usage was at 53W. (I set the tubro boost max limit at 60W). (240W adapter)

I also have Intel dynamic platform & thermal framework installed but I see no settings for it in the power plans. Would this be causing an issue?

 

Lol why, I don't care if you don't believe me

What would you want to see exactly?

 

What was your PL1 and PL2 limits set to? These are what matter. The PL2 is the absolute limit your CPU power can spike up to, it can only spike above the PL1 value for the duration of the turbo boost power time limit until it will power throttle.

 

I’m sure @D2 Ultima would like to see a video of your 7820hk running 5.1GHz in Cinbench R15 with pretty nice 1.270v. I’m sure 5.2GH is within reach, if you put 1.310v as Power management is unlocked. Same MSI laptop model as @Falkentyne and @Phoenix ? And what Thermal paste? Mx-4 ?


Gt73 and 7820hk + Liquid Metal if I remember correctly. And CM238 chipset.

 

not you, maybe u can check which person i quoted, which is not your post.

 

I want to know what EC mods are even done without the entire system being bricked since it's protected by SHA-1 encryption. Or is this some simple RW Everything register change?
I heard of some problem like power limit 2 just getting forcibly flagged on at any speed 4.9 ghz+ .....

So what's changed? EC Ram offset E4? Offset F4?

 

Not only me, I think @iunlock @Wormwood @Galm and @DeeX wanna see this 5.1GHz 7820HK using lower voltage than I have to use for 5GHz that's "nothing special".

Proof or stop telling people this is a thing, I don't care what you think but I care that other people will get false ideas.

 

The only reason I won't bother providing proof is because most people here like to talk out of their bum and won't ever provide evidence for their nonsense for most of the times, so why should I bother providing proof with my experience and test?

I could easily make screenshots and videos of the benchmarks etc, it would only end in the "Well, BGA still sucks my LGA is better", discussion, so I won't bother. Waste of effort, nothing else.

 

Because you're lying.

So, you're lying.

 

Thank you for proving my point.

 

You have no point, you're lying.

Literally everybody who knows these chips knows you're lying... so your arguement is that because people are going to hate on it, you shouldn't waste your time?

"I'm not lying. I have no proof, and will not provide proof, because you all hate BGA". This has nothing to do with whether or not you're lying. If you refuse to provide proof, you're lying, because your claim is astronomically implausible, and actually with what I know from what you said, and what you claim to be getting, physically impossible.

When you have proof, come talk to us. Until then, you have NO POINT, NO ARGUEMENT, and finally, ARE LYING. Stop feeding people lies about what they can expect about your non-existent product. I don't care if you delude yourself and believe your product is the best thing since the dawn of time; you can mess up yourself as much as possible. But don't tell other people that lies are fact, because too many buy on misinformation already.

 

Then how about sending me some screenshots via private message? By your own admission this would not take much effort and wouldn't be an inconvenience.

I'm not a member of the anti-BGA brigade, although I will admit that LGA does have some advantages over BGA, and a private conversation with me won't degrade into mud throwing and I could confirm you're not lying.

 

How far can j00 go with your OC'ing on Mobile i7 if MX-4 or Coolermaster High Performance is your preferred thermal grease ? Maybe read the whole thread.

 

Further proving my point.

You don't get what you want, hence you claim I'm lying without any proof like a little child that didn't get his present which he wished for for christmas, you can't possible know if I'm lying or not. Outright saying someone is lying despite telling the truth showcases that showing you any kind of evidence would only cause you do complain about something else and hence be completely pointless in the first place. I have much better things to do than making angry kids happy.

 

Maybe click on the Mobile i7 CPU information in @D2 Ultima's sig. I'm sure he know more about mobile processors than many others here on the forum or the web I'm quite sure his statements are not taken out of the loose air.

 

"You will deny the evidence so I won't provide any"

Lul ok I'm done. More productive to talk to brick walls. Nothing to see here folks, just another dude claiming unicorns are real who won't even film a horse with a paper horn stuck on it because "we wouldn't believe it".

My oh my what do we have going on in here?

*Chuckles...*

Sigh... (A big grin on my face and shaking my head...)

@Wormwood .... should I? LOL or just leave it be...

 

This has really turned into CPU Wars section.

 

@Danishblunt JUST STOP IT! this BGA 5Ghz lol
I'm sorry. I just had to comment with a laugh. I hope you don't take this offensive. You want me to stop laughing; then show me proof please

If not, then knock off them blunts bro. Plus rep for making me chuckle lol.

 

Don't, you'll make them cry. No need to escalate this even further. They don't need proof in any way shape or form.

Just let them rant on.

 

Just enjoy your OC on custom EC/BIOS from Svet and try your luck at HWBOT, I think you got a gold CPU that can OC a little further by downclocking the GPU a little. Just enjoy the adrenaline rush from your CPU in gaming or Firestrike benching,

 

Svet didn't make the custom EC/BIOS. In gaming there is no difference stock vs OC, OC is purely for bragrights.
Also no, I've gotten 5ghz+ on 2/2 systems.
Sadly I don't have more to test.

In the end who cares anyways?
It won't affect gaming anyways and when someone buys something for video editing etc, a ryzen/xeon based desktop is the way to go. It's way more beneficial to work on the GPU instead.

 

If you use CUDA for rendering then GPU is the best. Then again with OpenCL you can use nvidia gpu, amd CPU/GPU and even Intel to compete against CUDA.

 

pretty much proves that CPU's are getting somewhat obsolete.

 

It won't unless Intel and AMD are taken over by nvidia and ARM. Hahhaa. You must *know* that CPU is a master and rest every hardware are slaves to CPU. Just google Bus master, DMA and stuff like that. Pretty much confusing things to remember.

 

I said somewhat obsolete,not obsolete, I'm aware that a PC cannot run without a CPU, but the CPU is mostly outperformed by the GPU in a lot of things. A really powerful CPU is simply not worth getting anymore, unless you plan on something like making VM's etc. Once you got something like a 2600K, you have absolute no reason to upgrade at all.

 

In that case laptop CPU is abomination on planet earth just like @Mr. Fox @Papusan says.
No hard feelings I know what you meant. In the foreseeable future, CPU is gonna stay for 10-12 years then maybe GPU will contain a CPU just to save a cost or something after 12 years, who knows.

 

that doesn't make a lick of sense. Why would notebook CPU's be an abomination by my logic? It's actually a good point as to why CPU's might as well be BGA if anything.

 

BGA-> Limited hardware lifetime and increased repair cost etc.... You get what I want to say, correct?

 

Some prefer trash, bruh! And some prefer old tech as you can hear above. 54% slower and this mobile i7 is called high end chips by the reviewers From one of my older posts.

 

Can't argue about the repair cost.
All hardware has limited lifetime, also I highly doubt a CPU will die ealier just because it's BGA, CPU's are very rarely dying. If they die, it's mostly due to some kind of damage caused by water etc.

 

I think the OP is confused by seeing all these.

 

But when the motherboard fails you eventually need a new board containing CPU, GPU and everything else.

 

It will be like this...

 

Depends on board, BGA CPU and MXM combos won't have the GPU included.
otherwise good point. I don't know the pricing differences, when looking at ebay boards with a 4720hq seems to be pretty much the same as a socketed 4700MQ without CPU board.

I do think that high end GPU's shouldn't be soldered to the mainboard tho.

 

Where do you get all these gifs that simply blends into a situation?

Yeah we hope so they don't get soldered but that's isn't the case these days.

 

I'm not bothered about BGA CPU's, as long the costs are down, which they are, but the whole soldered GPU situation in some notebooks are annoying. Alienware and MSI turned from MXM ports to soldered on. It's much harder to get a MXM based system on newer notebooks which makes the whole thing sad.

 

And j00 who talked about MSI Titan, 5.1/5.2 and 1.27v @Falkentyne Can you, please show him pict of MXM if he forgot? Could you also post pict of max temp after Cinebench R15 with 4.8GHz ? Thanks

 

Me? I never ran my CPU at 4.8 ghz. That was @iunlock who did that. I don't even know if it would be stable.
What I do know is if you exceed 4.8 ghz, power limit 2 get forced on.

So, @Danishblunt what sort of mod did you actually do? To mod the actual EC requires disassembling it in Linux and then having to break at least two SHA-1 encrypted checksums, one which bricks the system after the flash is completed if it fails and another which bricks the system if it fails on POST check. So I'm asking politely, what exactly did you do?

Can't changing registers in RW Everything do the same thing? I already know that offset F4 seems to control some sort of "system current limit shutoff" flag. Sirgeorge tested that, changing the value 0C to 8C and his system shuts off at SLI full load. I was unable to find the PECI power limits in the EC RAM anywhere although I did find the "Hybrid Power" flag.which is register C6, but even when this gets flagged and PL2 gets set due to limited power, there doesn't seem to be a way to turn PL2 "off". E4 can be written to and changed but C6 just seems to get rewritten instantly

 

GT73VR with MXM 1070



GT73VR with MXM 1080:


-------------
Can someone tell me the difference in chip format on these? The 1070 has differentely aligned GPU and VRM positions than the 1080. I know something about "MXM 3.0" vs "MXM 3.0b" but what exactly is the format of each card that causes the different layout? Sorry for thread derail.
