Precision M4500 Owner's Lounge

No problems. Glad to be of help.

Let us know what sort of results you achieve.

 

Hi, I have the ThrottleStop but trying to get the benchmarking correct. I could download prime95 and ran it and watched my temperatures rise (stopped it at 70). Not sure how far I can go and where I get numerical output.

The other stress test seems to cost $.

I also have the high end port replicator, so power not a problem.

 

The Prime95 will not give you benchmark numbers - only do a complete torture stress test to prove the stability of your system with the overclock

The benchmark software you want is the SISANDRA (FREE) version

SiSoftware Zone

After downloaded and installed - run the Arithmetic Processor benchmark to compare your results.

As far as the temperature, 70 is fairly low. Intel doesn't start thermally throttling these CPUs I think until about ~100C and shutdown is at ~120C or so

 

Hi,

Got the software and here were your baseline results:

Baseline on the M4500
Aggregate Arithmetic Performance - 27.7GOPS
Dhrystone iSSE4.2 - 33.59GIPS
Whetston iSSE3 - 22.83GFLOPS

Mine are:

Baseline on the M4500
Aggregate Arithmetic Performance - 37.76GOPS
Dhrystone iSSE4.2 - 41.5GIPS
Whetston iSSE3 - 34.35GFLOPS

Mine seem different: Here is the processor information; i7 CPU Q 720 @ 1.60GHz

But, looks like we are getting reproducible methods.

My temp runs at 52 degrees C normally. I guess I have room to move it up. Thanks for the learning exercise.

 

I've made some adjustments in the settings that have resulted in more consistent benchmarks and lower temperatures for both the CPU and GPU on the Dell M4500 with the I7-940XM processor.

In TRL the following settings are used for Maximum Turbo Ratio Limits
1 Core Active - 30
2 Cores Active - 23
3 Cores Active - 22
4 Cores Active - 21

In TPL the following settings are used for Maximum Turbo Power Limits
Profile 1
TDP (W) - 250
TDC (A) - 250

 

I was about to try your setting but I cannot in program. Is there an unlock of some type I have to do in bios to use this program?

 

What setting are you talking about?

 

TRL and TPL. They are greyed out. I tried to reproduce the same settings as you.

Do we have the same processors? I think some are more locked down than others, as I read.

 

I think your processor might have locked settings. I am running one of the Intel "Extreme" series processors - I7-940XM which has unlocked multipliers from Intel

 

Unfortunately we are both right. I needed one of the "Extreme" versions. The software developer writes:

Well, when I get my M4600 I will know what to order. It is of interest that the same processor is used in another machine and someone has figured out how to unlock it (For a 500 Yen donation!).

Edited to include the words of the overclocking guru:

The only way to overclock a Core i7-720QM is by using SetFSB and that's only if your motherboard is supported by that program. Not all laptops are supported. It's trial and error because the clock generator chip is not consistent from one board to the next, even if they are the exact same model. A 920XM + ThrottleStop can run fully loaded over 100% faster than a 720QM so your best bet is to start saving up and then head to EBay with about $400 and get yourself a new CPU.

Even when SetFSB works, the performance improvement is marginal compared to what the Extreme beasts can do. BTW, this is the Core 2 Extreme overclocking thread. Your Core i7, non-Extreme CPU doesn't qualify in either category.
