Overclocking the GT 540M

[grenadier]

550m speeds work on my 540m. but not too much beyond that.

I've got my 525M benching 3dmark vantage stable right now at 800 on the core - 820 and the test still completes, but I start to see some minimal tearing / artifacting. Time to start raising the memory .

The cooling system in the L502X can deal with a ton of heat - even with these overclocks I'm only hitting ~68C load on the gpu. This thing was built to handle a 50W graphics chip so hopefully Dell will start offering one for the XPS 15 series soon.

I concur. I am able to play games at 740/1000 no problem. It does get up to 80 degrees celsius though.

[grenadier]

Final stable speeds for my 525M are 800 / 1050 giving me a 3dmark vantage bench of P5324 (up from P4096 stock).

After hitting 1000 on the memory additional speed increases only yield very minor gains (1050 gives me ~15 points in vantage) - looks like I'm going to leave it at 1000 for normal use.

dang you guy's 525 is yields better clocks than my 540m. Well that is just 3dmark though not a few hours gaming correct?

not hours but i had crysis 2 going for 45 minutes
full 1080p in low settings no lag

I'll have to check those speeds with my 540m....I'm looking to give it a boost. Maybe a bit lower, so I'll check with a couple benchmarks

I ran a bunch of benchmarks with the GT540m OC'd to 800/1050 and here are the following results:

Idle Temp: 47-52C (note these temps are on a chill pad)

3d Mark06: Default settings 1024x768
Score: 9688
Temp:  77C

Resident Evil 5:
1920x1080 Resolution (1600x900 gets me over 50FPS consistently)
No AA, No Motion Blur
Max Settings
Variable: 38.5 FPS
Fixed: 35.4 FPS
Temp: 79C

Street Fighter IV:
1920x1080 Resolution
No AA, VSync Off
Max Settings
Average FPS: 71.4

I've not yet went over 80C, but I'm getting ready to play Sogun II: Total War for a bit, so after a couple hours we'll see what happens, I run everything on High or Ultra at 1920x1080 with Medium Unit size and detail. The map is laggy sometimes, but the battles are awesome and silky smooth

i thought default 3dmark 06 was 12x10 res?

[joehempel]

Whatever it was, it's the default, 1280x1024 if that's what you mean...I don't know what 12x10 is.

I should add that Dragon Age II runs on High with 1920x1080 resolution quite smoothly at least in the beginning battle.

Hello, I did a 10% overclock on 540m, ran several tests on 3dmark06, 11, Cinebench, ect. but I experienced BSOD while benchmarking Metro 2033, hm what do you guys think... I am an Acer 5750g user though.
