E6540 Owners Thread

1. Yeah, min and max. This is just for when I'm plugged in and gaming. Keeps the clock speed locked.

2a. 99% is essentially the full, non-Turbo Boost clock speed. Setting to 100% will enable Turbo Boost, and allow the processor to hit 3.4Ghz and generate a lot more heat.

2b. Install Dell Power Manager, then use the High Performance profile for normal use. This profile has a min and max of 5-100%. Basically only utilizing higher clocks speed when it needs it.

3. I experience no throttling back with these "Caps". CPU maintains 2.4Ghz and 2.7Ghz without issue.

4. Yes, MS Flight Simulator X.

 

Turnbull2000,

Thank you !!! ... I understand now.

BTW, do you like the E6540 ? ....how long have you had it ? ... and would you recommend it for purchase ?
(I am planning on replacing my thinkpad T61 and have narrowed it down to either the E5540, E6540 or the M4800.)

 

Just got my E6540 yesterday. Windows Experience Index crashes (the laptop is just turned off halfway through). Someone in another thread said downloading new video drivers from Dell fixed that, but mine apparently came with the latest drivers... Any other tips?

And Dell calls the webcam "HD", but I'm only able to get 640x480 out of it.

 

Turnbull2000,

What "Min" and "Max" Percentages, are you using for - "Normal, Battery Mode" ?

 

I'm just using the High Performance profile, with dynamic CPU clock speed. You should have the power profile too. Just make sure you have Dell Power Manager installed.

 

Turnbull2000;

One last question on CPU profile:

1. How did you calculate that 95% = 2.4 Ghz ?

.... What is the calculation formula that you used ?
..... OR, did you run some CPU performance software after setting 95% to see what it listed for CPU Ghz, after you set the Power Manager profile to 95 % ? ... If yes, which software pgm ?

 

CPU-Z will give you the clocks.

CPUID - System & hardware benchmark, monitoring, reporting

 

I use the excellent Piriform Speccy64, portable version, to monitor clock speeds and temps. I just adjusted the processor % until I got the desired clock speed.

Turnbull2000,

Thanks ! .. nice pgm (speccy).

Jumbie,

How is your evaluation going between the E6540 and M4800 ? Anymore eval updates to share about these 2 models ?

 

Has anyone re-pasted with coollaboratory liquid or Shin Etsu or tx-4?
