4790k laptop overclocking?

has anyone managed to overclock this processor beyond the 4.4ghz stock?

i know it's a desktop processor and can get super hot inside a laptop, but has anyone tried to even get it stable at 4.5ghz or more?

 

It only hits 4.2GHz on 4 cores at stock.

And yes, people have gotten it stable past 4.5GHz.

 

i meant past 4.2ghz on all 4 cores. I'm thinking of upgrading and right now i have the 4810mq overclocked to 4ghz on all 4 cores. i don't think 200mhz extra would make that much of a difference for an upgrade.

 

TBH I don't see the point of going the 4790K route and getting a whole new system. Sell the 880M & 4810MQ and upgrade the sig rig with 980M & 4910MQ or 4940MX clocked to 4.3 GHz or above. 4790K will run super hot, so not like you'll do much better with it anyway.

Or just forget the 10% CPU upgrade and get a 980M by itself.

 

If you go the route Octiceps is talking about, you may be interested in purchasing the P170SM-A CPU heatsink (for the copper fins as opposed to your machine's aluminum fins) to better cool the CPU under your overclocks. Still would be cheaper than an entirely new system.

 

i just want a full new system because i want a 4k screen, SSDs in raid 0, 980m, and possibly the desktop processor because it also has more cache, i do a lot of video editing and plan on doing 4k video editing soon. plus the new laptops are thinner than the giant one i have now, so thats a plus

 

49x0MQ/MX chips have the same amount of cache as a 4790K.

Good luck making use of a 4K screen at 15.6" or 17.3"

 

Overclocking a 88W 4.2GHz desktop CPU to over 4.5GHz inside a notebook
God save us all

Context:
4.5GHz 4790K: 110-120W on 177mm2 die area. 0.68W/mm2
vs
GTX 980M : 100W on 398mm2 die area. 0.25W/mm2

Thats a fireball for you

 

Haven't found a need to OC the 4790K yet. I'm more concerned with the 330W PSU I got, it's massive and heavy. Fireball? Taxing things I use CPU for are encoding videos and compiling roms for N5.

4K video editing on a laptop screen, even if it is 3K/4K. Wouldn't you be better off using an external 28-32" 4K display?

 

have you seen the difference between a normal macbook pro and a macbook pro with retina display? its night and day. thats 1800p. so therefore, a 4k screen will be even sharper than retina display. should be awesome. it'll help with 4k video editing and doing photoshop with high megapixel photos.

too bad that 490xxmq chips arent available in the new sagers with 4k screens =(

 

Look up retina display again. It's not 1080p. And Retina isn't necessarily about the resolution, it's the PPI, Pixel Density. A phone with 1080p but 400 PPI is technically a retina display, pixels so dense you can't see the pixels, that's what retina display is about for the most part since the actual viewable use of display is the same, 1600x900 or 1080p, even if it is a 4K display.

4K resolution on a 17/15" screen just doesn't seem practical to me. 4K screen that is downsampled to 1080p, yeah that sounds great to me. 4K video editing on a 15/17" screen? Yeah, just nonsense to me. I would want at least a 27/28" then.

 

i didnt say retina display was 1080p, i said retina display is 1800p. i think that what it was when i last checked, my point is, 4k would have more pixel density than retina display from apple. plus better brightness, colors, and contrast

 

Why would you think that? My Nexus 5 retina display PPI @ 1080p is far higher than any 4K/5K display for PC. Apple's retina for 13" PPI is higher than that of their 5K retina for 27".

Resolution and PPI aren't exactly correlated. My Nexus 5 phone has 445 PPI @ 1080p. Galaxy S6 1440p will have 556 PPI.

And Apple's retina is not 1080p. It's 2880x1800 for 15" and 2560x1600 for 13" PPI of these laptops are higher than 27" 5K display.

 

exactly, i just said the resolution on their 15 inch is 1800p. you keep repeating it back to me. my point is, a 4k ( 2160p) screen on a 15 inch will have more ppi than a 1800p screen on a 15 inch.... thats what im trying to say...

 

No. Someone interested in video editing should know what you're saying is wrong. 1080p implies 16:9 AR and resolution of 1920x1080. Video editor should know difference between 16:9 or 16:10 (Apple) and what 1080p or 1080i is.

 

Yeah, I owned a first-gen rMBP for a few weeks when they came out 3 years ago. It's super sharp but there is no additional screen real estate compared to 1440x900. If you turn off scaling in Windows (OS X doesn't allow this) and run at 100% DPI, everything is super tiny and unreadable.

For color-critical work a 4K laptop screen is not ideal since these are all extremely limited in color space with high Delta E (even post-calibration) compared to something like an HP DreamColor 1080p. The much more accurate colors will make a bigger difference than pixel density since I've already established that you won't fit more on-screen due to scaling.

Not necessarily. AFAIK rMBP displays are still sRGB and calibrated extremely well in typical Apple fashion. Most of these recent 4K screens that are showing up in laptops aren't even full sRGB and need calibration.

 

I've seen retina displays. They did not impress me. I much rather the slight lack of crispness and the 120Hz and honestly quite good view angles and 72% NTSC gamut of my current "crappy" TN panel

 

from what ive heard, the Sharp IGZO 4k has amazing colors and 98 percent sRGB. ive heard its much better than the samsung one. either way, the offbrand clevo screen im using is horrible. sager was out of the screen i wanted, so they gave me a 50 dollar off discount for this horrible and dull colored matte screen. i have to use external monitors half the time. my old asus touch screen laptop with 1080p was so much better looking than this 1080p off brand screen. 4k full screen video and photoshop and gaming will look amazing

 

100% sRGB == 72% NTSC Gamut
aka my "crappy" TN panel.
72% sRGB == 60% NTSC gamut == the new IPS panels selling right now, especially in the 17" market.

Good luck getting 90% NTSC or 95% NTSC these days though.

 

maybe it was 98 percent ntsc. i don't remember. i just heard it was worth the extra 150 dollars to upgrade from the samsung 4k to the sharp 4k

 

There is only one 90% NTSC 17" panel, and it's an AUO glossy one. Matte usually have lower NTSC gamuts, and there sure as hell isn't an IPS with 98% NTSC gamut in 17" (mainly because you usually only get 90%, 95% and 100% NTSC).

 

i just want the sharp 4k 15 inch igzo ips glossy display. im sure it's a step up

 

It definetly will be.. it's supposed to have great colours! Get what you want in the end.. You will be the one using it and not us

 

Pretty much, I'll just add that you need to correct for the actual die space allocated for the cores vs "all the other crap". When I ran these numbers on the 4770K vs GK110, the 4770K had roughly 2x the thermal density.

I'd be interested to see if Hawaii XT's thermal density is higher than GK110. But my gut feeling says 438mm^2 vs 561mm^2 means the answer is a resounding YES.

I haz panel!!111

Yes it's the AUO B173HW01 v4, and you will fall in love the second you lay your eyes on her it.

 

So, the answer is yes. I was one of the first on the forum to 4.5, but still was warmer due to an improperly seated heatsink (screw or mount is messed up). So I recommend it. Not for the OC, but for one of the best processors you can get in a machine. This is excluding Xeon e5 in the p570wm sli (still a beast). The 4940mx wouldn't be bad either. But the zm has some little extras. It really depends on your needs and if you like mods! Dealer's choice!

 

weird, havent seen any fireballs coming out of my machine lately...

 

Do you mean volcanic explosions?

 

4.5ghz on single or all 4 cores?

 

All 4! With max fans, expect high 80s or 90s, but with advanced TIMs (maybe delid) and pads, maybe able to go further. Most were on gelid extreme while doing so, I did it on mx-4. As I said, dealer's choice!

Edit: you must under volt to achieve this. Don't just set multiplier 45 and say "look at me, look at me, 4.5ghz." Familiarize yourself with xtu and how to properly adjust values. Do so at your own risk.

My every day settings are 40 multiplier all cores, 40 multiplier cache, -65 voltage offset Vcore, -110 voltage offset cache, auto fans. So don't run your hardware at the max always. The 4790k is made for a case temp of 74.4 degrees or so. Laptops are so compact, consider the core temp as the case temp. So your every day turbo temp should not be much more than this (think of 80 as an artificial cap). This protects warranties and the life of your hardware. Try to keep the chip at max mid 70s (80 for spikes, etc.). Also, find a new test program. Prime 95, lynpack, occt, etc. Artificially drive temps so high. Use something else that does stress the cpu but doesn't strive to do so by driving temps. You may need multiple programs to qualify it for your needs!

 

I currently only overclock my 4810mq to 4ghz on all 4 cores when i'm rendering a video in premiere or after effects. sometimes for gaming. I'd probably do the same thing when i get a batman laptop

 

Except 4ghz is stock. If all your thermals are correct, you could probably do some of that at higher levels. But yeah, 4ghz auto fan is pretty quiet!!! You'll enjoy!!!

 

wondering if i could go past 4.5ghz on all 4 cores. i have gpu acceleration for my final renders, so my cpu only maxes at about 60 percent used during the render

 

It depends on thermals, etc. If it is a reasonable temp, maybe. I can't tell you for sure.

 

thus far it looks like 4.5 Ghz is the reasonable (without / with minimal thermal throttling) ceiling one can reach in the ZM series. if you want to go above that i guess ull have to delid and use liquid metal TIM

 

Jesus, a 4790K is already hot as hell in a desktop. Why anyone would want to overclock it is beyond me.

 

if only the 5960x was in a laptop

 

Eh... Just wait for a socket support for skylake-e/cannonlake-e next year with 14/16nm video cards if that is what you're in to. Clevo is releasing its roadmap later this month. Who knows whether there is a successor to the P570wm in the works or not.

 

oh, thats easy: cuz we can

 

That would be much worse than 4790K

 

Clevo would be quite dumb to put the 5960x in a laptop... Mr Fox would love it but the heat generation and weight will be absurd.. dual PSU's will be like a stock requirement especially if it's a SLI notebook!

 

Not even *I* would buy a 5960X in a laptop.

 

I would too. Or at the very least a 6 core 5820k until I could afford to blow money on a 5960x.

 

Not from what I heard. What is it, 4GHz clockspeeds draw 400W under load? And that's going in a SLI laptop? You'd need three power bricks or keep it at stock, far less the heat. I think X79 is still the better bet for it.

Let's hope they skip Broadwell-E and go to Skylake-E and be done with it. Haswell and Broadwell bring nothing very good to the table, but take a good deal away. Especially in the mobile sector.

 

Is the power draw really that high only just 4hz?! Kidding me

 

400W for the system is on the low side for a 5960X @ 4 GHz plus a couple 100W MXM GPUs in SLI.



4 GHz is +71W over stock. A stock 5960X is 140W, so at 4 GHz it's already drawing 211W by itself. Add 200W worth of GPU plus everything else and the system is well north of 400W.

Then there's the matter of heat. Overclocked to 4.2 GHz to match a stock 4790K, the 5960X draws +114W over stock, or 254W. I don't see how anything short of a liquid cooled laptop can handle a 254W CPU without melting.

 

Cheers for the info. Ok nice. These external PSU might need to evolve some. Cooling aside, for 4.4Ghx there 2 x 330w would do the trick provided it had laptop GPU's and they weren't OCed.

And yeah @D2 Ultima 3 x PSU would suck. I could live with having 2 or even better...1 that was enough.

 

Good luck cooling that...

What's the lowest profile water block and thinnest tubing, I wonder? I could see someone possibly shoehorning that into a big thick machine like a P570WM.

 

Yeah, Haswell-E can go to hell.

 

Aw come on, its not that bad. Just definitely not made for laptops. Running a 5820k in my new X99. The thing is an absolute beast. 4.5ghz and holding steady around 55C after hours of BF4.
