M11x R1/R2/R3 specs. Including Thermal (TDP) info and Chipsets

Hey all,

Figured I would get the info for everyone, since some people are confused about cooling and other things regarding these systems. Let me know if I missed anything, I tried to make the list as complete as I can regarding info about the CPU, Chipset and Videocard. I couldn't find anything really official about the GT 335 tho.

*Power usage may also be increased do to CPU/GPU overclocking.

 

are the cooling systems different between the 3 models?

 

The GT 335M's 35W TDP figure is incorrect. It has to be less then 28W as the GTS 250M and 350M, both based on the GT215 core as the 335M, are rated for 28W, have all shaders enabled (96 vs 72), run with higher clocks (500mhz vs 450mhz) and with a higher voltage as stock (.95v vs .9v).

 

There was talk about the GT 335M being 23-24W, but nothing confirmed. An additional 10W to reach 35W for the GT 540M could explain the louder fan. Though R2 owners are overclocking their CPUs and GPUs like crazy, and R2's cooling system seems fine.

 

The voltage isn't touched for the CPU OC and VBIOS modding the 335M isn't enough to make a major difference as it doesn't add much more heat (+3C in OCCT Stability test) or take away much battery life (I tested and it lost 5 minutes).
The 540M runs at a higher voltage then the 335M at stock that may be part of the higher TDP (.98v instead of .9v).

 

In the beginning there was nothing and then Alienware did create the M11x.
Yea verily did Alienware create them both.

M11xR1 SU7300 and M11xR1 SU4100.

And it was good.

Intel SU7300 3MB cache , VT-x and Intel SU4100 2MB cache, no VT-x

 

CPU power consumption also depends on the frequency it's running at. Overclocking from BCLK 133 -> 166 MHz (i7 going from 1.2 GHz to 1.5GHz)seems to approximately add 4W according to a well known formula. Not saying this is too accurate, since there is much more to the science. Just saying that frequency itself adds to the power consumption.

So a few Watts extra each for CPU and GPU when overclocking doesn't seem unreasonable at all. Also add the unlocking of TDP limits from ThrottleStop when turboing.

I think the R2's cooling could handle R3, there is no clear answer to why there is a louder fan. I am tired of speculating about it too now. Just disappointed.

 

The R3 fan table seems to be changed by Dell between the review and the release. The review 2657M i7 units are shown to be loading at ~90C. The i7 R3 users have the fan running full speed at 65C. A method to lessen turbo throttling?

 

Wouldn't surprise me if this is the true reason. Higher temperaturs means higher resistance, which means higher power consumption. By keeping the temperatures down in an aggressive way, it will take longer to exceed the TDP value, or not at all, and turboing could go on for much longer. This was observed on the M14x, which seemed to be able to run at full turbo speed for really long duration tasks, according to StevenX. The M14x as we know also has very aggressive and loud fan.

Could be possible to control the fan speed with third party utility.

 

Tossed in the other processor, and updated the GT 335m TDP. Anybody have a more official page on the 335m?

 

Thanks for this!

 

"*Power usage may also be increased do to CPU/GPU overclocking."

Should be "... due to..."

 

Guys.. I need some serious input here!
Alienware M11X R3 - Intel QS67 Chipset.. Would it be possible to run a msata SSD from the WWAN port?! Come now, is there really no one that has tested this on an R3 yet?

Thanks guys..
=)

 

You left out the i3 in the R2.
