XPS 16 GPU overclocking

Seems like I got a stable ~800/~890. If I come above 900 on memory the whole thing freezes, and the same thing if I come around 820 on core. Average temp. under full load was 80C.

 

Too bad that you can't get your mem up higher, the mem is the bottleneck on these cards, but that's still a decent overclock, and your temps are great.

 

Mmm, overclocking... my old love As the games I enjoy don't cry out for me to overclock my SXPS16, I haven't done it yet, but I can feel the itch to play with it for fun.

 

So I tried this a few weeks ago along with removing the air filters underneath (I had already changed the thermal paste to AS5 as soon as I purchased the laptop) - I noticed now external displays plugged in by d-sub (VGA) flicker randomly. There is random screen tear when literally doing nothing. I haven't had a chance to test HDMI or DP as I haven't moved my laptop from work yet but am I the only one experiencing this issue?
Temps have definitely gone down, I always use a laptop cooler anyway; the internal fan used to spin up from time to time - very noticeably loud - but it hasn't since.

 

I've tried few different things to lower notebook temperatures but not removing bottom of it. Is it safe? (of course with using on desktop) I also have cooling pad which should provide additional protection. And does it really help with temperatures?

I also have 9-cell battery but I suppose that shouldn't to interfere with that?



I also want to ask about GPU OC. There are some interesting BIOS mods in this topic:

I have Ati 5730, can I achieve similar result by moding BIOS as by using OC programs mentioned here?

 

You can use the laptop with the bottom panel off on a flat surface with the 9-cell battery.

If you haven't already removed the dust filters (I'd recommend that) then you'll probably size a nice improvement under load.

If you already removed the filters, it should only make a small difference. I ran my computer for a few hours with the bottom off (as well as the plastic piece that goes where the air comes out, and it really seemed like only a small difference.

 

By dust filters you mean these few small rectangular.. not sure how to call it but something that looks like little transparent plastic?

I haven't try this. So you say it can drop the temperatures by few degrees? I can start from that.

 

Yes, those are the filters (3 of them). The one that corresponds with the fan (square one) should make the temperature drop at least a few degrees under heavy load. The big filter and the small filter barely made a difference.

 

Ok, then I will try this first. Thanks.

 

I overclocked to around 725/950 and was hitting 95C + Shutdowns when playing bf3 beta.

Am getting the 130W adaptor and hoping the A13 bios will use this to the max to prevent so much throttling with the 4670! Have also blown out the exhaust fans with compressed air.

Think it'll run better now? Worth overclocking again??? May take the bottom cover off and put straight on the cooler.

Any thoughts /ideas?

Cheers
