I was wondering:
Before I signed in the forum I spent a whole week to read the 300 and something (at the time) pages of the p870 thread.
I don't quite remember who was, but I believe that one of the heavy benchers here, that was using two 980m in SLI on his config found one (or both, I don't remember) of his GPUs not working for a while. That made me wonder, if that didn't happened by stress of use with higher voltages.
Having that in mind, and wanting to clock mine further, I'd like to ask:
what you guys think that would be a safe voltage increase for a 24/7 overclock on the 980Ms?
(of course, with dual 330w PSUs)
right now I'm using with no voltage increase:
+150core/+250 vRAM for witcher 3
+195core/+250 vRAM for everything else including Firestrike Extreme

I really don't know. I don't know even where I should look for performance improvement from overclocking RAM from 2400 to 2666.
Now I'm hunting a instability I've found only in Witcher 3 in a few scenes of the game, which I believe it may be GPU overclock. but it don't happens on anything else.
On my desktop (with two GTX 780 in SLI), if my GPUs were unstable firestrike extreme would crash, but now I can use clocks MUCH higher than I use on Witcher 3 on Firestrike and it don't crash. Se my post above...
So I wouldn't overclock the RAM untill I find the right clocks for Witcher 3 (or right voltages, as I hadn't increased voltages on the GPUs yet), to not add a possible new unstable variable on the systen. -

I was able to overclock my 64 GB Samsung 2133 MHz. RAM from 2133 MHz to 2400 MHz and even 2666 MHz and I thought it was stable, passed the AIDA64 benchmark and score was improved, BUT when I play NFS Rivals, after a while of playing, the framerate would drop to like 5 FPS and becomes unplayable, both on 2400 MHz and 2666 MHz. So stress testing/benching is one thing then actual stability in real world apps/games is another. I had to revert the RAM overclock back to stock. -
This is my first test of ↓↓↓Wprime ↓↓↓ with raid o and everything stock clock speed (all settings default- Noone tweaks and 2133 ram) Same stock speed as @Mr. Fox when he run the first test rewiev of this monster(see the image). I should have had the same low Wprime score because of Raid 0 as others in the thread, but I get a better score in Wprime although I put my 950 Pro drives in Raid0. Something is strange/fishy... I use the Win crippled X completely stock without optimization. This is to see how my Killer-Edition work with all hardware + Os with no tweaking. Ambient temperature during tests 18.6 degrees Celsius.

I am probably way too late to the party, sorry about that, but my advice would be NOT to remove that portion, let me explain my point of view : if you remove that you will give that fan more direct air... the good thing is that you will most likely see lower temps for the GPU the bad thing is you will diminish the amount of forced airflow along the motherboard. That fan is obstructed on purpose so the air is forced to come across the motherboard cooling it and also cooling other components as well like the RAM for instance. With enough "direct" air from a direct unobstructed vent beneath the fan not only that the motherboard will heat up more (but you will not be able to monitor that) but also most likely the fan will not be able to cool the m.2 slots and RAM slots beneath the keyboard that efficiently... I've looked at the design and monitored the temps on my m.2 and they are influenced a lot by the fan speed, motherboard temperatures and m.2 activity.
The only scenario when I will encourage the modding it will be if you are always using a laptop cooling pad that is constantly pushing air across the motherboard because it has more holes for the air to reach the motherboard and various other components.... Although not so sure about the m.2 slots cooling though. I for one never use a cooling pad because it adds height to my already high laptop, i have an P870, and my wrists are not happy.
Please share some numbers (and pictures) if you have before and after the mod... it will be interesting to find out how well everything evolved.Sebastiao Liparizi Neto likes this. -
Hi all,
I have been looking at the difference in price between the stock bios clevo P870DM and prema bios P870DM. The price difference is about 15% or $500, so my question is after overclocking using the prema bios what is the excepted performance increase over the stock bios. I realize there will be variation from system as to how far you can overclock the cpu and gpu, but I am looking for an average percentage. I should also state that I am traveling a lot at the moment and I don't want to carry a second power adapter if I don't have too. I game and do a lot scientific computing using multi-core cpu processing, where I generally max out all available threads. What would be the real world difference actually be? Any help/thoughts would be much appreciated. -
I ripped off these useless covers when I got my laptop. The first I started was to delid processor and test wprime. See temperature in idle and maximum load in the picture in the previous post. I use always a U3 cooling pad, so remove all covers have nothing to say for me

I recently installed a new MacBook Pro 15" retina display and all the bells and whishes possible... top configuration. The owner wanted to have Windows 10 on it also so I made the installation.... I had plenty of time to see MacOS in action on a highres display and windows 10... Windows 10 has lots of issues using a highres display... had to scale things to 200% to be usable (i know it is a 15" but still) not to mention bad ones (unusable) like printer drivers (2015 HP printer) menus and text overlapping. Office 2013 has bad icons issues and some other bugs... definitely not ready for 2 or 3k or 4k.
MacOS was perfect on the same screen, everything was looking good, fonts were sharp, scaled perfectly every time, every single icon was crafted for high resolutions.... I had to give it to them... it looks beautifully... and remember guys... I don't like Apple, the overpriced hardware and it's OS'es.
Bottom line, even if you can cope with 4k on a 17 inch screen our beloved OS manufacturer Microsft STILL does not have an OS ready for 4k or 3k or.... they funny thing is Microsoft promised us from windows 8 times that it will make it look good for high res screen... and it's W10 time now and still has plenty of issues...Sebastiao Liparizi Neto and god1729 like this. -
Hello everybody,
it's been a while, ever since the forums' revamp I haven't had much time to spare at all. I've just gone through the whole thread page by page and I have to say finally there is a machine that has it all. Over the past couple of years things have been looking rather grim in the mobile world, I believe @Mr. Fox and I share the same opinion in that regard ever since our time in the Alienware forums which has sadly come to an end.
So now I'm in the hunt for a Phoenix and I must thank everybody here for providing such valuable information, most notably @Phoenix as well as the ever helpful @Meaker@Sager and of course @Mr. Fox.
I currently work in Paris so the task of finding the best reseller is gonna be of prime importance. I definitely want a reseller that offers @Prema's mod so it's gonna come down to either Mythlogic, Eurocom or Hidevolution.
@Phoenix presented a very compelling argument for Hidevolution especially with their global warranty, so at the moment I'm leaning towards them and I definitely would rather have Eurocom's branding on my machine rather than Sager's.
My main question is how much time should I expect for the assembly both from Eurocom and Hidevolution? I know that Mythlogic are the slowest at 15 working days which really shocked me.
Any help would be appreciated as I can't wait to finally have my hands on one of these machines!
Cheers!

Well everything except a decent headphone amp:
I've tested the headphone out from my P870 with these headphones :
1. AKG K550 - 32 Ω - these worked best, at 100% volume there were loud enough but the bass was not 100% up to what it can do on these.
2. Beyerdynamic DT 770 Pro - 80 Ω model - with the laptop volume set to 100% you cannot call the laptop amplification decent... the headphoned do not get to decent levels... and the sound is lifeless
3. Sennheiser HD 600 - 300 Ω - don't even think about plugging these.
I had an portable, extremely cheap USB DAC+amp Fiio K1 around 40-50$ that was light years ahead in therms of amplification.... not to mention the actual DAC part... but let's not talk about the DAC part because it's decent enough in the P870... I am not saying that it's good, or great... just decent... but decent is enough for the most of us while gaming.
I am disappointed that up to this day, in a flagship laptop, they did not manage to add an decent amp to the headphone output. I am not asking for much, not a super expensive DAC, just a good headphone amp that can drive an 50-100 Ω headphone without problems.
A decent amp circuit is just a few $... for a flagship I say it is possible without much of an effort.hmscott likes this. -

Contact Ted from HIDevolution telling him you are an NBR member to get a special discount.
1) You can have them order the Eurocom Sky X9 for you with the Prema BIOS pre-installed and covered under warranty, that would cost an additional $200 USD from Eurocom to cover the warranty because now the system is using a non-manufacturer BIOS and if any component goes bad, Eurocom has to bear the cost so $200 for that extra bit of peace of mine is worth it IMO.
2) HIDevolution's global warranty is perfect for international customers like us because they will pay for shipping if anything goes bad. If it's a small part that you can replace, they will send it to you first so you don't ever have to be without your system.
3) It took 2 business days for my system to ship from Eurocom to HIDevolution and 1 business day for HIDevolution (despite them being so busy) to check for dead pixels, quality checks, and ship it to Dubai. I received my system in Dubai within 4 days literally.
4) Their shipping rates with FedEx/DHL are very cheap and fast. Like if I were to order the same system from any other manufacturer, the shipping was almost double the price.
Just email Ted from HIDevolution (the sales email is on their website) and he should be able to sort everything for you
Finally, see why I recommend them and am loyal to them......

There were a few individuals that seemed to have card failures but make note that when investigated a few cases knew their performance was low from the beginning.
My cards have been pushed hard and they are perfectly fine. You can check the score below. But as said heat is the natural born killer for all components.
My rule for everyday clocks is <=1.1v and keep them cool and you will be fine. Usually with premas vbios you can run between +100 to +200 at 1.062v pretty stable and painless especially on the primary.
For those of you wondering the worth of prema check out his benchmark page, it speaks for its self.

Thank you very much! Again!
And at what GPU Temps shpuld I be worried with?
If it stays under the throttle limit (92C) is enough, or should I try to maintain it below a specific point, for aditional security with higher voltages? -
Well, I'm getting ever closer to ordering a machine. I've decided on most of the configuration ... but I'm having an extremely difficult time deciding on which panel to get.
The geek in me is very interested in the 4K one (higher resolution has to be better, right? I mean ... it's ... it's ... well, it's just higher!). In reading the posts, I haven't missed the fact that there are those of you who aren't big fans of the 4K. But I'm not a gamer, so any issues that arise from that activity don't affect my decision. I do write software, so text is very important. Up to a point, a higher DPI (or, if you prefer, PPI) should be sharper thereby reducing eye strain. However, I gather there is a scaling issue with text and icons in some apps. Eve's favorite fruit seems to be able to employ high res screens on laptops that look good ... so I'll assume it's possible; and I've also found an app that purports to fix that problem to some extent by reverting to the scaling method employed by Vista, Windows 7, 8, and 8.1.
On to the questions: if it's not worth it now, what do think the chances are that it will be in the future (1 to 2 years)? And even if this problem works itself out in the future (due to updates), would it be better to get the FHD panel now, and then replace it with a 4K one when it's a reasonable thing to do?
Any thoughts, suggestions, or opinions are always appreciated, thanks.
p.s., I plan on keeping this machine for a while (5 years or so), so I'm trying to think long term.Sebastiao Liparizi Neto likes this. -

No, higher resolution means it is more taxing on the GPU at the native resolution, less battery life, the 4K panel sucks and cannot run above 60hz and no GSYNC.
Let alone that things look super tiny at the native resolution, and we all know how crappy Windows DPI scaling is.
IMO, any 4K screen looks like a joke on a screen with less than 32 inch of size. For laptops, the best resolution is 1080P (FHD)
just my 2 centsLast edited: Feb 26, 2016Sebastiao Liparizi Neto and Mr. Fox like this. -
Just to be safe I would treat 92 as the last resort red alert. I usually suggest keeping them under 85 and prefer less than 80 to be safe under most conditions.

You just want to be under 90c. Even with thermal throttle point at 92c it's not a great practice to run the GPU at 90-91c for long periods of time. Once you get down into the 80s or lower you are good to go. If you can get a stable overclock with the GPUs and you are in the 80s then great! Just steer clear of 90s.Sebastiao Liparizi Neto likes this.

Like my idle temps on a 42x4 overclock with adaptive voltage to -150mV offset is 39C, very cool, run an AIDA64 stress test and within a minute the temps would go up to 95C (in gaming it reaches 80C but I want an overclock that is stable for everything). If I set the CPU to 44x4 on all cores, with the same voltage offset, the temps reach 100C quickly then it throttles down to 4 GHz
If I go lower on the offset voltage to even -160mV Windows wouldn't boot so I am stuck there that's why I want to see what kind of settings you are running.

I know different CPUs react differently with OCing and such. Silicon lottery baby. You never know what you're gonna get. But those temps and clocks seem way off compared to my machine. I don't think I had a single crash due to OC on the CPU until I tested 46x. I didn't test it much because honesty I don't feel like tweaking it for the extra 100mhz.

Hmmm...
My GPUs get to 80c/85c already without voltage increase with my current ambient temps here =(
I'll lower vRAM clocks to see if it gets better...
My CPU temps with 4.1ghz stays at 60c-62c with -150mv. It starts to get unstable at 4.2ghz and abive that windows don't boot with -150mv.
I tried 4.3ghz with 1175 static voltage, but TS and cpuz was reading like 1300mv and the temps reached like 82c and sometimes close to 90c.
What I found very curious is that when I let it on adaptive, the 4.1ghz clock stays rock solid and never change at all, the voltages do, but not the clock.
When I let it on static voltage, both clock and voltages changes a lot, and the clock stays around 3ghz and clock up only when needed it seems. -
Spartan@HIDevolution Company Representative
I've had very bad luck with static voltage as well.
Try also lowering the cache voltage to -150mV while keeping the multipliers at 0 (ie. stock/41x) and then increase all CPU multipliers to 42X, that runs perfect for meSebastiao Liparizi Neto likes this. -
Adaptive is generally the way to go. Not saying you can't run static.. But this voltage ordeal people always speak of... At least in my opinion.. Is not something to sweat too much. I had hours upon hours of gaming with an OC on the CPU and simply left voltage stock. After a while I ran -50mV just to see if I could shave any more temps off. But reality was everything was perfect.
Now in your case your ambient temps are working against you. Your gaming temps in your room are hotter than I ever am in. So that definitely plays a part!
I'm not saying some people aren't having issues with voltage.. But this is what I see in my case!hmscott, Sebastiao Liparizi Neto and Spartan@HIDevolution like this. -
Thank you for your thoughts, I appreciate it!
The points you make are all valid ... and, if I were a gamer, it would be a no-brainer (which is also an apt description of me). But most of your (once again, perfectly valid) criticisms of the 4K monitor don't apply in my situation. My main concern is the scaling issue with text/icons. What I'm hoping to obtain with a 4K monitor is sharper text (which a higher DPI should give me) and with the added benefit of more real estate (assuming the scaling is less than 200%). So, for me, if the scaling issue can be satisfactorily resolved (now or in the future), then I'd (more than likely) get the 4K panel. If it can't, then I'll get the FHD.Akaraah and Sebastiao Liparizi Neto like this. -
The 4k screen is definitely a good screen due to its resolution(obviously) and more importantly the large colour gamut(88% Adobe RGB tested by notebookcheck). If gaming isn't the primary focus you don't have to worry much about g-sync or screen overclocking either. That said there are scaling issues, increased load on the GPU and reduced battery life @Phoenix pointed out. I would wouldn't worry about eye strain reading on 1080p except if you plan on reading super tiny text which I'm sure is worse for your eyes and you rather use a decent font size. All things considered it's down as usual to your preference.
Since you plan to use the machine for a long term, upgrading to 4k in the future isn't a bad idea(especially with the eDP interface) as most scaling issues should be fixed as 4k becomes common and you can also expect better displays supporting new features and technology like HDR and OLED.

I understand, I rarely play games also, but the scaling issue is horrible, like it would scale right in a few windows, then in other windows it's all blurry like in gpedit.msc, services.msc, etc. as if there was no scaling and you are running on a non-native resolution.
The other thing about increased battery consumption and you being stuck to 60hz takes out all the joy and smoothness.
Once your eyes get used to the 75hz on these 1080 screens, it is very hard if not impossible to go to the 60 hz, it's like I can see the screen flickering.
But feel free to try it and let us know when you get it. I guarantee you will regret it.hmscott and Sebastiao Liparizi Neto like this. -

@Phoenix and @Firebat246
I'm just back home and I'll try that.
I had the -150mv on ring too, but always set the ring multiplier the same as the core. Now its x41 just as the core. I'll set it at x0 and try the core at x42 and x43 again to see how it goes.
For the GPU, I still don't know...
I'm checking to maybe travel to US again in two weeks for the Game Connection and GDC conventions (I'm a game developer), so I'm planing to buy some mx4 for the gpus and CLU to delid and use on the CPU heatsink as well. Maybe after that I'll be more secure about overvolting the GPU with better temps. -

Hey buddy. Saw your post, but since you don't have OC Experience and I'm still learning myself fro the gurus here, I felt that they could help you better.
I would say to not use XTU. Since you have a Mythologic system, you can do it through the BIOS. But if you don't know what youre doing, you can mess things greatly.
For the CPU, first try only to lower the voktage of the CPU and its ring by -150mv. Let the clocks stock at first. If its unstable, you can disable c states like I did.
For the GPU you can try for a start +135mhz on core and +100 on the memory and then play something heavy for hours on end. My gpu overclock is stable everywhere, except in Witcher 3. Try also some heavy benchmarks to test stability, like firestrike extreme.Spartan@HIDevolution likes this. -

Mines are performing very well so far!
Whats holding me back are my temperatures here in Brazil. I'm a little afraid of burning anything on the cards because of it.
But after I apply some mx4 I'll add some voltages. +100mv for a start and check how it goes.
I'm using msi afterburner only because of the riva statistics server. Is there any problem if I use afterburner (only for the riva thing) along with Nvidia inspector (to apply higher voltages) on the same time? -
So any suggestions on the OC using the BIOS way?
-
I'd suggest staying at 1.150v and below unless you can keep the temps at 50C or below max on load. That's what I was doing, max temps were around 46C on load for me.
Don't use nVidia Inspector and MSI Afterburner at the same time. Use nVidia Inspector to increase voltage and if you really need the Rivatuner statistics server, you can download HWINFO and set it up to work with the rivatuner OSD. That way you can use nVidia inspector to increase voltage/clocks and you can use HWINFO+Rivatuner statistics server to have an OSD of your hardware.god1729, Sebastiao Liparizi Neto and Omnomberry like this.
