Dell Latitude E6410 i7 720QM Works!

Thanks, what would be the best cpu upgrade in your opinion? Dual core i7 with 35watt tdp?

 

Well it 560M is what I would recommend.

Difference between i5 560M and i7 640M is very small, but I would assume the cost will not be.

What do you have inside?

 

Right now I have a Core i5 520M. Looking to get a few extra years out of her.

 

The only upgrade would be to i7 720qm to make sense. If you are not going to stress the gpu while you work, then the quad i7 could serve you well. Since it will increase the resell value of your laptop as a whole as well.

 

Hi,

For dell E6410 maximum cpu should not be more than having 35TDP , for e6510 you can go with 45 TDP because fan of dell e6510 is available with around 9.xx CFM and for dell e6410 it is around 4.0 CFM so it blows heat very quickly

it also depend on room temperature but e6510 is safe bet.

 

Sorry to dig up an old thread.
I bought an i7 720QM based on the report in OP. Tried installing it in my E6410 (i5 540M, NVS 3100M) but the laptop wouldn't boot with the new CPU installed. Keyboard LEDs blinked to say "System board error". Could anyone who's successfully upgraded provide more details on their laptop? MB revision perhaps?

 

Is bios up to date?

If you got the NVS, should be working right out the box. What's your FULL specs?

 

Having recently done this myself, I suspect there are other people who might be interested.

• I used a 740QM i7 Clarksfield processor - of course using the NVS 3100m (8gb of ram). The cpu turboboosts to its max of 2.93 GHz and boosts properly in other configs.

The temps were dissatisfactory so I applied Coollaboratory Liquid Pro and it made a worthwhile difference. When running Prime95, the temps max out at 80C which is exactly what the i5 was getting (It wasn't using CLP thermal material though). Idle temp is always 10C higher although when in use, it's generally within a couple of degrees of the previous 560m i5. I have performed the copper-mod to the gpu which may have assisted the temps a little. Working temps with programs and browsers running are in the 60's and in the 70's when running 3D games.

A few notes:

• 65w AC adapter was totally insufficient. 90w worked (just) although the cpu sometimes downclocked to 900mhz and stayed there. 120 and 150w has been solid and works great.
• Coollaboratory Liquid Pro is well worth the risk in this case. Noctua NT-H1 is easier to apply but the temps were still too high for my liking.
• I ran medium 3d games and the i7 didn't throttle - the previous poster did mention that under heavy gpu load and cpu load, the cpu would throttle so bare this in mind.
• Definitely upgrade to A16 bios - If you don't love your laptop then try without and watch the fans go into overdrive before system shutdown.

Turbo Boosting to 2.9GHz

Quite a pleasing outcome - everything works as it did before and the temp difference is acceptable. I'd second the opinion that the 55W XM CPU's would be a nightmare under load. The extra 10W TDP of the 740QM (45W TDP) translates to a guaranteed 10C increase in idle temps so I'd expect the XM's 55W TDP to exacerbate this even further.
