Dell 17r N7720 SE - user review

[c_man]

OK, so I originally got overall P2300, then something 'happened' that prevented the boost working, so I started getting P2050. I monitored the GPU clock using GPU-Z to discover this problem. The solution, if this is also happening to yours, is to reflash the bios with the 'same' version from the dell site (A01). While troubleshooting, I also upgraded to the 304.79 drivers, these didn't significantly affect benchmarks though.

CPU-wise, you should be getting around 7500 in '11' and 21500 in Vantage. Make sure you close as many running processes as possible before running. I'd guess it's possible AV software may be interfering too - I uninstalled McAffee and replaced with Microsoft's free one.

I have read about this before. Could be 1 of 3 things:

1. A protection in vBIOS if you try to OC, at some point it will enter a safe mode of some sort and stick with it;
2. A bug somewhere, maybe still in vBIOS as even if safe mode is triggered, it should perform normal after a restart;
3. Driver problem.

Since everything is so new, we have to wait and see what happens and if someone will fix it.

I know some guys got around 2900-3000 out of 650. The card itself can do it.

From my tests, 650 will top at 91°C and start down clock at that point (the stock will go from 835 to 790, I did not see it go any lower).

If you can keep it under 90, you can OC it nicely.

In games I see it tops around 65°C. But maybe I did not play that much. In fact I just did it for ~30min. to see how it works.

Display

I have seen a report for this already with a Chi Mei display in a 7720 SE. But mine is different.

I have the LGD02DA panel.

Where can you see the panel name in the laptop?

Has anyone installed Win 7 from a USB 3 flash drive? For some reason my 17R SE either hangs or does not work properly with USB 3.0 boot devices e.g. Win 7 setup, Ghost System Recovery. The problems only occur at startup, once into Win 7, they work as expected.

Please use this program EnTech Taiwan | Utilities | Monitor Asset Manager, I see it is the fastest.

Or if you already have AIDA64, info is under Display/Monitor section.

I have tried it and it does not work. I guess it's due to the lack of USB3 driver or I don't know. I had a bit of trouble with that driver even in W7.

Thank you! Mine is like yours

And how do you like it?

The million dollar questiom is (still) how good does BF3 1080p, medium settings or MW3 1080p high settings running with this rig.

I got tired after gaming for about 45min. to test some possible settings on different screen resolutions.

I was happy with this:

Is it good, is it bad ... I have no idea.

It got my 650M working real hard. First time I see it reaching 80°C and staying there. Room temp 32°C.

Maybe some settings can go higher, I've stopped here. Feels like a nice balance. With every setting going up, temperature goes up as well.

You guys tell me how this looks.

PS. On my machine FRAPS does not work very well and keeps crashing my driver. I have tried both Dell's and Nvidia's drivers.

thank you............thats really nice to see.

ps....turn off MSAA and set effects to medium (then just overall quality to high)......better fps, stunning image quality

ps....did you play BF3 with OCing ????


he he he, i love it.....we are owner of $1000 Inspiron laptops and still beats both Xps & Envy Rigs in gaming........WOW

[c_man]

No OC, you can see on the right window in runs at 835. Why OC if it runs OK.

Like this?



Feels kinda strange, don't know why. I was happy with my original setting. But I'll give it a try.

[KSMB]

Splendid.....( i didnt notice that image before , thats why i asked)

MSAA eats fps bigtime, thats why i told you so. Just use the settings you like yourself,Gt650 is great in shader tight games so its no problems

[Rassal]

What was the average FPS at that resolution/settings in BF3?
