Overclocking Laptops (3DMark11)

AsrielDreemurr

Hey There!

So there's been a lot a talk on oc'ing laptops and most people say 'it's idiotic to oc laptops because of their crappy cooling' but... here's the thing:

 

Overclocking laptops IS possible, if done safely, while keeping an eye out for temps. I'm about to show you some graphs on the results. The results are hilariously low, even I'm saying so. Before I start, this is the monster (not) that the test bench was on. NOTE: I'm talking about overclocking the gpu, not the cpu. Any sort of cpu overclocking IS idiotic for laptops. Period. GPU's vary

 

Name: HP Pavilion 15-n215si
Cpu: Intel Core i7 4500U 1.8GHz 
Ram: 8GB (2x4G) Samsung Dual Channel DDR3L SDRAM 1600MHz
Motherboard: Hewlett Packard 2166 U3E1
Gpu: Nvidia GeForce 740M 2GB (2047M) DDr3 (lol)
MONITOR 1: 1366x768 15.6 HD BrightView LED backlit Generic PnP
MONITOR 2: Samsung 1600x900 S20D300 Anti-Glare
STORAGE 1: 931GB (1 000 204 886 016 bytes) Western Digital WD10JPVX-60JC3T0 (SATA 3 6.0Gb/s) HDD 5400rpm
 
Speaking temps, this specific cpu is hot on average. My CPU during the benchmarks reached a max of 86 degrees Celsius and was constantly hitting it's  2.4GHz turbo frequency, meaning it did not thermal throttle itself at all. Honestly though, it was a bit above my comfort spot, which is 80, but I can understand. 90 and above would be me ripping the laptop apart and replacing the thermal compound. 
The GPU on the other hand on average without Oc'ing, sits at 40+- degrees Celsius. The hottest it reached was 74 degrees. My comfirt spot is personally 65-70. A bit above but anyway. There were three tests. Stock speeds, then core clock upped by 70 MHz and memory by 200MHz, which is what I normally use. Then I cranked it to ultra (well, ultra that ACTUALLY ran without artifacting or other BS like black screens) by turning the core to 110MHz and memory to 260Mz. 
 
The results were, err, bad. But the results weren't for showing off, they were to show that OC'ing laptops aren't always bad. Just keep an eye on that temp. I suggest installing Speccy as it monitors your cpu temps with ease. (note that there is a BS offer in the installer, so make sure to read.) (ALL TESTS WERE RAN AT 720p WITH THE BASIC EDITION OF 3DMARK11 - 1M 30SECONDS)
 
*One observation is that the physics score actually drops a small amount from test 2 to test 3*
 
So, here are the results:
 
Score: P1682

Score: P1837
My recommended overclock:

Score: P1928

The results do show that a mild overclock with a laptop can improve performance. Now I know more than half of you will disagree, but this is just my opinion. And this is just me showing my discoveries. I did once manage to make it through with the Core clock at +135MHz (the max the client allows) but there wasn't really a difference. It was still P1928 and the combined score was 1561, only 10 above the +110 test. 
 
So here is the conclusion: If you're stuck with a laptop like me waiting for an upgrade, in my opinion, it's worth it to overclock your gpu if it's compatible. Just to squeeze out that extra 5FPS is Crysis 3 :) Practically, I noticed an fps increase on Minecraft by about 15-20fps using my recommended settings and my gpu never hits higher than 65 degrees Celsius. (Don't over do your overclock as you probably still want your gpu to last you, that's why the "ultra" on my graph wasn't ultra. I've once managed core +135MHz and memory +275MHz. But that strains your gpu quite a bit)
 
Lemme know if you disagree with laptop OC'ing

If you play Geometry Dash, would you take the time to rate this demon? 14986973 ;3;

It depends on the gpu. 

 

My laptop has a 660m for example is well recorded on the internet to be very capable of +600/800 (from stock) core +300-400 memory without any degradation issues (and only very minor overvolting).

 

I myself have a very extreme overclock that costs me about 10C but that's not really a big deal (I use a cooling pad so whatever)

 

Laptop overclocking on gpu's on most cases in a computer by computer method, but in fact almost all the nice ones I have run into have massive headroom (if you are willing to deal with noise.)

 

For me this also results in about a 20% increase in fps on DA:I on min settings (just getting it above 35 fps haha)
