Clevo Overclocker's Lounge

Wait you overclocked the 120hz 1080p display to 144hz or you're referring to your QHD 144hz display?

 

I'm using my external display yes.

 

Has anyone actually tried overclocking the 120hz 1080p display? I wonder if the "3K" 120hz display will also go higher.

 

connection-wise, you would theoretically be limited to 144 Hz at 1440p. Since we know that UHD displays can only be overclocked to 64 Hz, we know the current bandwidth limits:

3840 * 2160 * 64 Hz = 530,841,600 pixel per second

530,841,600 / (2560 * 1440) = 144 Hz theoretical bandwidth limit

id be curious to see if my theory is correct ^^

interestingly, according to this calculation, i should be able to clock my 3K screen (2880*1620) up to 113-114 Hz before bandwidth is limiting. however, im only able to reach 65Hz, but that might also be based on the panel itself, not on the bandwidth...

additionally, it could, of course, very well be that the QHD 120Hz screen uses a higher bandwidth connection that previous UHD screens

 

The 1080p panel cuts out if you try and raise the refresh rate beyond stock.

 

which panel would that be? in what machine?

 

The panel ssj92 asked about and is in my machine

 

so i guess it already runs at the bleeding edge of its stability at stock ^^

 

I've had two fhd lg panels for clevo come with dead pixels. Maybe their oc is a bit too much as it is

 

Do you think that is just because it's not stable at any higher refresh rates or because there's some sort of safety that cuts it off when it detects it is higher than 120hz?

 

so a question from me again, somebody has some OC experience already with the 1070? How far can it go and does it use JMicron Vmem, i hope not? Cause i could get a P775DM2/3 dunno tbh, with the 1440p 120hz display but i'm unsure if i should pull the trigger already or invest in a 1080, but to be completely honest with you guys i MOSTLY only play competitive games ( Overwatch 95% of the time, Quake Live too but i shouldn't mention it honestly for a 1070) on the Notebook and rarely top notch games but still want some future proof ofc. Mostly i just looked up some tests for the desktop 1070 so i could get somewhat a point of direction, but still.

 

For a little more, pick up the P870DM2/3 with a single card. It is a couple hundred more, but allows you to later move to sli if you want, search out the T heatsink for better cooling with a single card (or get a DM3 with a grid and a single 1080, although that increased the cost more significantly). If you are getting a 17", might as well leave more possibilities open...

Perhaps a limitation of the display controller, i'm not entirely sure if that or it's programmed in.

 

New better Cinebench R15 - 1068 cb score from the BGA-KILLER for first page @Phoenix Up from 1065 cb
http://hwbot.org/submission/3344932_papusan_cinebench___r15_core_i7_6700k_1068_cb?recalculate=true

 

Panel oc has nothing to do with dead pixels. And they won't sell panels overclocked and at their limits.

 

As per usual... ambient temp average? Max fans? From what I see, it'd be impossible to stream with that 6700K of yours at whatever speed you've got it at. Which disappoints me.

Clevo doesn't OC. That's up to OEMs like Sager, and is handled by your BIOS. For the 60Hz panels, anyway.

 

at this point, u should switch to DDR4-3000 to squeeze out additional points on cinebench

 

I need to talk with my wife about ^^^ this HAHA
Better ram isn't the highest priority now (used too much on the house). I can probably squeeze out more points with what I have
I will more likely save up cash for a new machine. And Kaby lake is around the corner. Not a big gain in performance, but maybe a improvement

 

just saying, cinebench is actually surprisingly sensitive to ram speed speaking of which, just put an order in for 32gb corsair ddr4-3000

A room with the fire on so a bit variable. On the warm side. I would advise not overclocking when streaming.

I find it amusing that these days a laptop able to game at a consistent 500-550w draw from the wall while running two fully unlocked 80 class GPUs at above stock boosting desktop speeds is disappointing.

 

It's only disappointing because I don't think I could make full use of the CPU the way I'd like. Either way, I suppose I'll have to just see for myself with one of them one day. With my current RAM and just a bit of compression added, streaming 720p 42fps overwatch takes up to around 50% of my processor; I can't even play at 120fps or I'll cleanly run out of CPU power. A 6700K, 500MHz faster + IPC benefits or no, isn't going to let me sit at 120fps with the same stream ability, even with some equally nice RAM. Hence why the overclock is something I'd love. Honestly I'd like to see where about 75% of the huge single heatsink in the P870DM2 single 1080 is left to the 1080, and that extra 25% more cooling potential is donated to the 6700K. I thoroughly dislike the idea of having to drop to single GPU, yes, but I think I'd rather stable, cool, extra performance in more demanding scenarios than just gaming (which I do perform).

 

You could get the grid heatsink with a single 1080 then replace the thermal pad between the CPU and GPU heatsinks with an appropriately sized block of copper and liquid metal paste.

 

Don't overclock the GPUs and give extra room to the cpu then.

 

I thought that without doing what @Q937 said above, the CPU cooling is not shared with the GPUs via the grid?

 

No, through the standard Sager BIOS.

As for the idea you would have to check the bi-directionality of the heatpipes.

 

Building on that, did G.Skill ever put out the DDR4-3200? also, if I read it correctly, the corsair 3000 may be add-on xmp profile. Could someone check on that?

Nothing else has been released recently.

 

yep i checked myself for those 3200 mhz sticks and even found a report for 3333 mhz modules, apparently just recently presented by g.skill ^^ but no details on pricing or availability yet.

from my experience, corsair sticks have been PnP thus far, might have changed though. curious to see what the default speed will be when the machine boots up.

Sent from my Huawei Mate 8 NXT-AL10

 

ok, so it looks like both the G.Skill and the Corsair modules are XMP enabled and boot up at 2666 Mhz at default:

its strange though that there is so little info to be found online, especially on the corsair sticks...

 

It's because people don't care enough about laptops for big demand, really.

 

I unterstand your Point completely but i dunno if i can resist the discount, P870DM is a Level Up sure but costs me about 1k more with 1x 1080 and the Vapor chamber HS. I can get the P775DM3 with the specs i wrote for about 1.5k without parts but with 1070 ofc which seems to be quite the deal

Gesendet von meinem Nexus 6P mit Tapatalk

 

No, spec out a DM2 with a single 1070, that way it matches the specs on the 775DM3, then. You won't have the vapor chamber, but different resellers will have upgrade gpu kits. Just wait for Volta before upgrading and save between now and then (they'll have a heatsink available to change it up and the dm2 and dm3 are the same except heatsink and couple minor things)!!!

So now you see what I found and my concern... But really, I just want to see them side by side...

Sent from my SM-G900P using Tapatalk

 

No need to be concerned really. The gains in 3000Mhz ram are questionable let alone beyond that.

 

Or you could just run your ram at 3100 mhz now or flash it to a 3200 xmp profile.

As you can see, this ram is running at just under 3100mhz

 

Do you think the 2800mhz module will be able to handle that at 1.3v?

 

what sticks are those? g.skill or corsair? any news on the testing of the latter yet?

Sent from my Huawei Mate 8 NXT-AL10

 

It does not need 1.3V. The timings might be wrong for our machines. And only need to be readjusted.

In this picture you will see I have already ran 2400 mhz ram at 3000 mhz on 1.2V


@jaybee83 G-Skill

 

My concern is more variability in whether I'll hit 3100-3200 for my own satisfaction. If it wasn't an xmp profile, I know I'd have more room to play is where my thoughts were at...

You'll never know until you test it.

 

Not exactly sure what you are getting at?

 

Off-topic post: This is Mr. @Papusan in the snow with his laptop overclocked to 5.0 GHz >>>>

 

what is a normal 4.0GHz but idle voltage?

I idle on 1.3V, but the min processor frequency is set to 100% from power plan.

 

If you are on stock voltage then it's fine.
And the voltage is different for almost everyone, but in somewhat of a range.

 

If the ram is able to clock higher without xmp, which often uses extra voltage, then you can usually push it further or tighten timings more, of course with stick variance. In other words, on a desktop, you can push many 3600 stocks further than 2400 in many cases, with exceptions and variances, with conditions of OC (like temp and voltage) held constant. That is all I was getting at...

Hummmm...... I'm thinking you are misunderstanding the situation.
1: XMP can use higher voltage as well.
2: That was not XMP I was using. Nor was it flashed.
3: Over clocking ram has a lot to do with bclk & some dividers, which are not open as of yet on the DM2/3. Or at least, not on my machine.
4: I have not even really tried expanding on how high the ram will over clock. I just thought it was odd that meaker needed so much voltage when he was only at 15-17-17. maybe for 15-16-16 or 14-17-17, but that is only my opinion and not a set in stone fact.
5: I also know about what voltage does to ram over clocks and when to start adding it to make things tighter and or more stable. Not sure where I said you can not add voltage? Only that is was not needed as yet. And it's still debatable as to if it actually works. I did that over clock in all of 3 minutes, just to see if it would work and run. When I have more time, i'll investigate further. If the voltage actually works I would assume you would be able to more. No doubt there.
6: This is still on a stock bios with no mods of any kind.

Quite different from a desktop where you have other factors unlocked to further enhance memory over clocking. I would suspect that 3k ram can hit 3600 mhz, but then that has to actually be unlocked in the machine to do so. Ergo, XMP/Flashing to get past this or lots of trial's and error's, but one of the timings you need to make that job easier is not exposed to the bios, so that also makes things that much harder to get stable. It's set to auto and no way to change it yet.

(3600 stocks further than 2400)
Hummm, well so far I did a 600 mhz over clock, so there is always that. I would have thought that a worthy over clock?
3000 mhz needs to be at 3600 mhz when it's all said and done.... And given that it can probably do this, the system is not setup to do so.....Yet.
I don't even think it can do 3333 mhz ram that is out. Since the system is set to a max of 3100 non xmp. (And other underlining factors)

Now I have no problem being wrong, should that time present itself, but as of today using current conditions without flashing and blcking and locked bios. 3100 is max.
As to how tight the timings can go...Is still up for grabs.


A better question might have been....
Can that be done using custom. And the simple answer would have been. Yes.

Question...are these timings
DDR3-2133 - 2400MHz@CL11-13-14-28-228 CR-2T custom SPD
better than these... My Kingston in my P570WM3


I only ask, because i'm not a memory over clock expert. No matter how hard i try to think I am. And some times lower is not always better...

 

I need some help ;_;

I am admin, disabled smart screen disabled UAC... some programs still require me to right click and run as admin... anyone knows how to solve this?

 

Not really a oc Lounge question. You make a new athread about it.
You will either need to take ownership, or reset permissions.

 

HaHa. Tweaking the Os should lying under the OC thread as well, LOL

 

Still looking for the solution to it.

Seems that some games cannot run in DSR without beiung out of program files folder...

Another thing, on p775, max gpu draw is 215W. lol. The laptopy can run in 4K DSR and @Phoenix might love to know that running it like this can render madVR at 4K image quality on a FHD display.

Seriously, this is something really cool that people should consider doing.

 

When I run GeForce Experience and it optimizes all my games, it automatically sets DSR and a 4K resolution.
