How to Supercharge the M11x with Core i5/i7 UM CPUs

[unclewebb]

I had issues with wPrime too but when I moved it into the Program Files folder then it worked fine.

I'm glad to see you are seeing some improvement. You could also try bumping up TDP to around 50 and see how that works out.

The 520UM tested yesterday was not giving any turbo boost when fully loaded while running wPrime. What multiplier does ThrottleStop show when running wPrime with TDP/TDC set to the default values?

Can you post a screen shot of CPU-Z and ThrottleStop while wPrime is running?

Something is wrong with your test system, then, because TB has always kicked on for wPrime benchmarks (and other benchmarks) for me, and my scores in the benchmark thread here aren't any better than other people with the I5. If TB didn't kick on for a <50 second test, it would be quite useless. Perhaps it was limited via the power plan that was chosen because it can be turned off in the power settings, and then ThrottleStop was overriding the power plan.

Here's a pic like you ask to prove it (linked due to its size) http://imgur.com/HexNe.png

I just watched cpuz without Throttlestop running, and it showed TB active during the wPrime 32m test.

Edit: glad to see it's helping with longer benchmarks!

Unclewebb, I'm going to run the tests now for you. But would you prefer O/C FSB on or off? I am very lucky in that my m11x i7 O/C's stable to 166Mhz

M11Ash: Use whatever settings you like. The more different data the better.

corwinicre: It was not my test system. I was helping an inexperienced user with his M11x yesterday and he was getting zero turbo boost when his i5-520UM CPU was fully loaded. His CPU was running at the default 8 multiplier and that was it. When a CPU is fully loaded, the power profiles shouldn't make any difference as the CPU should be running as fast as possible.

Can you use ThrottleStop to return your CPU to default TDP/TDC settings and show a screenshot of ThrottleStop while wPrime is running? I don't understand why your CPU gives you full turbo boost while his CPU was giving him none. A different stepping maybe?

Here is part of his log file:

As soon as the C0% load went up to 100.0%, his multiplier dropped down to the default 8.0 multiplier and was stuck there.

Is there an economy power profile that he might have been using that disables the full load turbo boost?

If TB didn't kick on for a <50 second test, it would be quite useless.

That's the problem with the Core i7-720QM. When all 8 threads are fully loaded, it gives you zero turbo boost because it is operating beyond the turbo TDP/TDC limits. You're right, that is useless and those CPUs have the TDP/TDC settings locked so there is no way to fix that problem.

Here is a picture of my results. CPU is i7 (Stepping 5, Revision K0), overclocked to 164MHz FSB, High Performance setting, on battery. TDP and TDC set to double the old value.

UPDATE: Also tried tripling the TDP and TDC values as well, but performance increase is negligible compared to doubling the values.

[unclewebb]

Thanks zephir. Is that a 620UM? What TDP/TDC values did you use?

[zephir]

Thanks zephir. Is that a 620UM? What TDP/TDC values did you use?

It's 640UM. TDP is set at 20W, TDC is at 60A

i5 @150

1st run TS off 4 threads
2nd run TS on 4 threads double TDP/TDC to 20/60 from stock 10/30
3rd run TS on 4 threads TDP/TDC 30/90
4th run TS off 2 threads
5th run TS on 2 threads TDP/TDC 20/60
6th run TS on 2 threads TDP/TDC 30/90

[M11Ash]

OK some help please guys, wPrime can't seem to find my hardware its just stuck on a loading loop when I start it up.........

[tassadar898]

i5 @150

1st run TS off 4 threads
2nd run TS on 4 threads double TDP/TDC to 20/60 from stock 10/30
3rd run TS on 4 threads TDP/TDC 30/90
4th run TS off 2 threads
5th run TS on 2 threads TDP/TDC 20/60
6th run TS on 2 threads TDP/TDC 30/90

What stepping and revision of the i5 do you have?
