-150mv with stock clock should be enough voltage in most cases.
My CPU does -120mv @4.5 (cinebench, firestrike, 3dmark11) but can't pass linx 20times.
Linx 0.6.4 avx 20times could only be passed with -78mv and it should be the most stable voltage.
That's why I am using it with @4.5@ -78mv now.

It's hard to wait for prema mod bios

 

I am a paste boy. Yeah sure I did paste.
I am not only talking about temp but the fan speed.
Fans should be maxed above 70c or 75c but it just doesn't

 

So is anyone other than Eurocom actually shipping the P775DM currently? I've been waiting for that model over the P870DM.

 

No, not yet. The keyboard metal plate appears warped and somewhat cheap.

Still working on getting Windows 7 installed.

 

Does anyone know how I could listen to a 5.1 surround sound system from Youtube?

I have a P771DM-G.

 

I've looked into this for a long time and wound up at youtube doesn't support 5.1. It encodes audio at 2.0 so you'll never get a 5.1 stream out of it. Even if th source was 5.1. All the youtube vids that say 5.1 in them are in fact 2.0.

Hi.This is my first post on any forum, though I've been following forums silently for a few months now. I understood the iGPU doesent drive displays but is it possible to use it as a secondary gpu for DirectX 12 Multiadapter?

 

I dont know what happened. Last week it was all over the place. It went down to 8100 with some settings. Today its better.

In Firestrike I just got 8419 with -50 and 8390 with -100.

I have the 330w power adapter. CPU is at x42. GPU at stock settings.

 

Is your cpu at 42x for just 1 core or all 4? Mine defaults to 42 for single thread and 40 for 4 core operation. That's where I've left it for now.

FYI, you're probably crashing Linx because of the Skylake bug with AVX extensions:
https://communities.intel.com/thread/96157?start=15&tstart=0

Apparently the fix is already created, it's just up to OEMs to ship the fix in a BIOS update.

On a side-note, I feel like the 6700K must've been fixed as far as voltages for Oceanic shipments. I can't get any further than -50mv before it gets sketchy (reboots from desktop etc). This was ordered in early December.


EDIT: On a related note, just so I'm not going crazy. What voltages are you guys seeing with -120/150mv undervolts?

Mine peaks at ~1.21V in XTU benchmark and around 1.18v in the CPU stress test.

 

@ -163 which is what I run for daily use I peak at 1.091v during xtu. Temps between 62c and 69c with auto fans, 54c and 63c on max.

Interesting, I previously couldn't undervolt that far but now I can get to -140mv with similarly low volts (~1.09 under the stress test). Temps bounce around a tonne though between ~67->75 with auto fans (it's summer here so ambient is a bit higher than usual.

 

I use [email protected]. In XTU about 1.3 or so..

 

No, for more details use search it has been talked about it many many times before.

 

I dont know whether I crashed linx 0.6.4 avx but I've succeeded passing it 20 times @4.5 (-78mv)

 

Tried search(on nbr and chrome). Can't seem to find relevant discussions or details. Could someone please link me to the relevant topic/ explain. I need to know this before I consider buying the 750dm(and some other things)

Need to know what?
p750 and p770 both DMs and ZMs dont have iGPU video output.
You can only use dGPU which is 970m or 980m.

What more do you have to know?

 

Whether the igpu can be used in the future to boost the overall graphics performance. The 750dm in its current config doesn't seem to be VR Ready and its the only clevo on offer in my country(India).

Sent from my Micromax AQ4501 using Tapatalk

 

I dont think igpu can be used in the future neither. At least now.
I dont know much about VR but I am pretty sure iGPU can not be used in current MOBO.

 

Even if the igpu COULD (and that is a big could) be enbled through some software/bios gimmick it will be in vain since it is not hardwired to any of the display ports (both internal or external).

 

Its 42x for all 4. The drop isnt much. When I get time, I am going to try more combos of multiplier and voltage offset.

I had a P750DM that I bent the pins on. With that one, I couldnt go under -50 without crashes. I got a new one with the same processor, and now I can go -100 with no crash. Havent tested further yet. Its probably not the 6700K limiting you.

 

I get that. But since it will play slave to the dgpu master it shouldn't need display outputs..right?

I don't know if there is any computer out there can use the igpu (intel) with any gpu cards (amd or nvidia) like xfire/sli, let alone this model in particular.

Im assuming that the 'mainstream' CPU in the second demo in the first link is a z170 based desktop, the same chipset used in these clevos.

Sent from my Micromax AQ4501 using Tapatalk

 

I do believe that that thing is in very early stages of development and could take a while before it gets mainstream. Just saying'...someone correct if it's the case.

 

It's very theoretical, but the iGPU can be used in a limited fashion via reverse Optimus down the line (physical outputs not needed, it would be piped to the dGPU framebuffer). Thing is there's not much of a point doing so unless you have software that can make use of some Intel specific acceleration. It cannot and probably won't ever be able to be used to simply increase frame-rate in 3D applications.

As far as VR, I suggest giving up attempting to get that running in a laptop setting.

The 980M will be perfectly fine for most VR demos and things (given the Oculus recommendation is the desktop 970 which is roughly on par with an OC'd 980M). But even the desktop 980 will NOT be enough once proper Triple-A VR titles come out (hell, my 980Ti is probably out as well). I've run the DK2@1440p and Vive@1440p and the 980Ti "just" handles that. The lack of resolution in the headset means you really have to downsample or pile on AA heavily to avoid aliasing artifacts.

I would at least wait for the Oculus CV1 to start shipping and get some more concrete numbers. I haven't found any clear indicators about how things like EVE Valkyrie or Elite Dangerous run (every demo booth I've been to is running multiple Titan Xs or 980Tis. Even then, both those games take place largely in space, which is exceptionally easy to render. Once you start seeing high-poly ground-based stuff it'll really kill GPUs.

 

980mx is coming. if you haven't bought one, wait for some weeks.

 

^Wow did not expect this at all. So we're getting a Maxwell refresh. But where is Pascal!!

 

So just to get things started before I kick things off with a new thread... Looks like Clevo's press conference in March will be about OLED screens, and Pascal... Exciting!

 

Quick question. Does thunderbolt 3 use 4 of the 16 pcie lanes direct to CPU or 4 of the 20 lanes on the PCH passing through the DMI, or is it more complicated?
Since the mxm card uses the former and the m.2 pcie slots use the latter, one or the other could be affected by eGPU/PCIe SSD through thunderbolt 3(please correct me if I'm wrong). I read somewhere that the DMI already bottlenecks two PCIe SSDs in raid 0 to some extent

Sent from my Micromax AQ4501 using Tapatalk

 

I'm fairly certain the TB3 lanes are drawn from the PCH. Most of the Intel diagrams just aren't specific enough. I believe the intention of the CPU lanes is to have them for GPU only.

Such as:
http://www.kitguru.net/wp-content/uploads/2015/06/intel_thunderbolt_alpine_ridge_40gbps.png
and
http://images.anandtech.com/doci/9485/Alpine Ridge.png

The whole CPU+PCH are just piled together as "Skylake Platform".

 

But thunderbolt 3 is also meant for eGPU. Won't the DMI bottleneck when eGPU and the NVMe SSDs run at the same time? Does someone have more definite info on this? @Prema @Mr._Fox @XMG @mythlogic

2)Also does anyone know more on Directx 12 on these systems now and for the future and if it is possible to utilise iGPU,dGPU and eGPU. I know this has been touched on before but no one has clearly explained WHY it is not possible in the future apart from no outputs from iGPU which really isn't necessary as the dGPU would used as primary?

Sent from my Micromax AQ4501 using Tapatalk

 

TB3 is not "meant" for eGPU. eGPU is just one of the possible applications. Just as desktop motherboards can also have GPUs plugged into PCIE slots serviced by the PCH.
As far as bottlenecking. It's a possibility, but unlikely to be an issue. Very few games would even remotely stress both a GPU and SSD at the same time (think about it, load times exist for this reason and any streaming systems are not huge file transfers).

Nobody has said it's not possible (from what I can see)....I've been saying it's possible almost every page now every time you ask the same question a different way. What isn't possible, is to use the Intel GPU in a a P750/770 right now as a standalone processor (because it's disabled) or as a regular GPU with output (no physical outputs).

A) Multiple GPUs CAN be used in conjunction and has already been tested. There are multiple modes to the Multi-Adapter tech in D3D12. Most importantly, any combination of dGPU + iGPU + eGPU puts it firmly in the "Unlinked" gpu structure. This means you have to address each GPU specifically, so the logical path is to task it to use the iGPU for other physics processing or post-processing. There are still complications to deal with there though, since your primary (beefy) GPU is still the reference point for your frame-times. This must also be built into the engine itself and it'll need logic to determine which tasks get send to which GPU. I dare say for the next few years, this stuff will simply go in the "too-hard" basket.

B) Physical output from the iGPU has nothing to do with it and I've said as much. BUT, the current situation is that there was no practical reason to keep the iGPU available with full dGPU laptops. As such, the common practice is to disable the iGPU at the BIOS level (as it is in the P750-770). The iGPU simply needs to be re-enabled again with preference going to PCIE for primary screen output and you can theoretically do DX12 MultiAdapter (unlinked) right now. Then you can address the iGPU as a standalone processor.

Thanks a lot Stooj. The "meant" was just poor choice of words . I have actually read and posted one of these links before. Though the last one seems interesting. I'm looking forward to someone actually testing this on one of the DM machines. Maybe ill try it myself when I finally decide which one to buy

Clevo has released a new version of Control Center 5.0001.0.38 and nVidia 359.14 for P750DM on their support; http://www.clevo.com.tw/en/e-services/download/ftpOut.asp?Lmodel=P7xxDM/P7xxDM-G&ltype=9&submit=+GO+
But it is impossible to download... Tried with a download manager and also just through Firefox, took the whole night, but the zip files extracts with crc errors. Clevo need to step up with their support and also to start release bios. If you download through EU ftp you will not get the right version of the file, go figure.

 

Any input on why my 6700k wont go above 4GHz?

No matter how high I set the multiplier it wont go higher then 4GHz

 

Probably the stock bios only allows limited amount of power for the CPU.
I noticed that stock clevo bios only allows 53 or 58w for the CPU.
This wont let any cpu to go higher for sure.

Stock bios of mine (from korean reseller) allows upto 118w and depends on the silicon lottery 6700k can be OCed upto 4.5.

 

This is weird: If I set the multiplier to say 45 and then run the benchmark or stress test in XTU it operates at 4.5GHz as it should. But if I then run 3dmark, prime or any other cpu intensive programs it wont go past 4GHz. If I then go back to XTU and run the stresstest again it won`t go past 4GHz there either

If i restart the pc all the settings but core voltage are reverted back to stock

 

That's right. That's how the stock clevo/xmg/eurocom bios worked on my notebook too.
The Korean Clevo Reseller's bios behaves a bit differently.
It does not allow ram OC but at least does not revert to stock.

 

I just d/l through the USA mirror. It downloaded in a few min and extracted correctly, but it tried to install verson 353.62. I canceled the install.

 

I have downloaded and installed the 359.14 driver, but the control center file comes with crc error.
Check whether the file size matches the one one the webpage can save some time for downloading outdated drivers.

 

I'm loving my laptop but find the cable from the unit to the power brick is too short.. can anyone recommend where I can get a longer one from please.. I'm in the UK.

Thanks

 

I totally agree.

 

Do you mean from the cable from the power brick to the laptop or from the power brick to the socket?
It's a standard kettle plug lead from the socket to the brick, you can pick those up just about anywhere.
As for an extension for the pin end, I'm curious about this too but with such a high gauge cable used it might be hard to verify the extension can handle the power load. I'm pretty sure it's a "power-DIN" or a Kycon KPPX-4P connector so any suitability high gauge extension that isn't crazy long ought to do the job.
I can't see any I'd recommend, though if you're handy with a soldering iron the parts are readily available.

 

Thanks..It's the one from the brick to the laptop..it is annoyingly short.

Yes, it's to short to keep the brick on the floor, I always have to put the brick next to the laptop... Don't know why Clevo did that.

 

Hi all. I've been lurking around here for a while, and just joined so that I can post some questions.

I've an Asus N82JQ, which is showing its age, in that it occasionally hard crashes when I put it to performance mode and do some intensive work... might be CPU and/or GPU overheating. It's also quite slow to process data on it (I'm doing Ph.D in Organic Chemistry), so I've been meaning to get a new laptop. My laptop usage is generally work (the software doesn't really use GPU), and I'd like to start playing AAA games like Witcher 3 in the near future. I'm rather tired to playing games and not enjoying them fully due to having to set to minimum settings or less. For work, I deal with a fairly large amount of spectroscopic data (2D NMR, think MRI but without the crazy GPU load, still a good amount of matrix data and arrays!), and probably will be doing X-ray crystallographic stuff soon too so I expect CPU load to be quite high (I don't know how well the software is parallelised for the CPU or to the GPU...)

I'm currently considering the Sky X4 or the Sky MX5 from Eurocom, with 980M as my GPU and either a 6820HK or 6700K for CPU. It's not urgent, and ideally I'd be buying the laptop sometime in March or June, but I can even delay it till December if necessary. I have a few questions to help me decide which is the better option to me.

1) I understand G-sync matches the FPS of the game to the refresh rate of the screen. How much benefit will there be with G-sync on a laptop, if the refresh rate is not going to be >75Hz to begin with? I'm not intending to game on 4K because I know 4K is a little overkill on a 15" laptop, so I'd probably bring it down to 1080p or some in-between resolution if possible, on standard High/Ultra settings (high textures, not a crazy amount of AA). I ask this question because I want to decide between the Sharp IGZO 4K screen, versus the LG FHD screen; the former currently is not G-sync compatible whereas the latter is.

2) How much is the performance difference between the 6820HK and the 6700K before OC, and after OC? I'm also quite curious about the power consumption of the 6700K with OC as I haven't seen much data about that (might have missed a few posts here and there, it's quite tough crawling through >1K pages over several threads). I don't see myself trying to OC like crazy, so probably no more than 4.0 GHz on the 6820HK, and... I don't know how comfortably the 6700K can OC so I'm not putting a number down for now.

3) I walk to work everyday (10~20 min each way), and I bring my laptop with me to work. In your opinion, do you think the P75X series is portable on a daily basis? My current laptop is ~2.4 kg, brick is only 300-400 g. I could handle an extra kilo, but the 230 W brick is quite heavy in itself too...

4) Has anyone tried measuring the travel distance of the keys on the P75X laptop?

5) I'm a bit concerned about relatively long boot times with some of the M.2 SSDs. Do you all know if this is a common problem, or one specific to this laptop or combination of SSDs?

Thanks for reading, and I will appreciate any replies greatly.

1) Most of the benefit from GSync is going to be to allow variable framerates without causing tearing, along with being able to (maybe) go up to 75Hz.

3) I'd recommend getting a second power brick for work so you don't have to carry that around too (that's what I do). I have a sleeve-style case ( https://www.sfbags.com/collections/laptop-sleeves/products/custom-fit-pc-laptop-sleevecase) that I love. I'm not sure how happy I'd be with a 10-20 minute walk with it, but 3-4 minutes doesn't bother me at all.

 

2) At stock for both, 6700k is better than the 6820hk. Now the 6700k can be pushed much further and there is evidence in this thread that the chassis can handle a decent overclock. I don't know much about the P650Rx (Sky MX5) and how well it handles overclocking the 6820hk, but I've read that the chip it self can easily reach 4.0 ghz.

3) I bring my P770DM to uni everyday and walk around with it all day and its not light. About 10 lb or 4.5 kg with the adapter. The P750DM should be a bit lighter maybe around 4 kg. So I guess it depends on how fit you are and if you can handle carrying 4 kg daily. Obviously getting a comfy bag to carry it in will be helpful.
