    Hey guys, I got in on today's deal for the i5 model and was wondering what sort of speeds fellow i5 owners are able to achieve (stably!) on their systems?

    I'm keeping my fingers crossed for a stable 166Mhz overclock, but that's probably just wishful thinking. :eek:

    I do not have my M11x yet... what is the multiplier for the i5? Aka, what is the 'max' speed of the i5?

    166 is the max I think.

    Thanks for the responses guys!

    Can you trust in that program? I used to have it, but the multipler was always at 13-14x but in TS is always 11-12x, well, having both open at the same time, who to trust?

    Can even the i5 have a 14x?

    I get stable OC with all speeds, but at 164 the wireless does not work, evereything works, but I get no internet, some already know, but my Lap can´t remember the OC, so if I put 160 after a few days or restarts, it goes back to 133 by itself, and that´s with all speeds, even 134, so when I want to use OC in a game, I need to restart the lap, put the OC, use it, because in the next reboot, is gonna go back to 133....

    Ah, thanks for the screenshot. The answer I was looking for was "x14", making 166 x 14 = 2324. I wasn't sure what the multiplier was, so knowing the base clock did not help me, lol

    When you overclock a UM processor to 166 MHz and you don't use ThrottleStop, your full load performance usually decreases. Try downloading the wPrime benchmark and run it without any overclocking and then run it again with your 166 MHz overclock.

    Downloads | wPrime Multithreaded Benchmark

    Without ThrottleStop, the multiplier can significantly decrease at full load so your total CPU speed decreases. Only Dell could come up with an overclocking feature that makes your CPU run slower when fully loaded. :rolleyes:

    Head over to the M11x Supercharge thread and learn how to test these CPUs and get the most out of them.

    http://forum.notebookreview.com/alienware-m11x/524257-how-supercharge-m11x-core-i5-i7-um-cpus.html

    ThrottleStop uses two high performance timers for each thread of your CPU and can determine the average multiplier for each thread of your CPU very accurately. It uses the monitoring method that Intel recommends in their November 2008 Turbo White Paper. Many other monitoring programs do not. You can fully trust what ThrottleStop is telling you. Everest and AIDA64 do not accurately report when one of these CPUs is rapidly turbo throttling. An i5-520UM has a maximum turbo multiplier of 14 but it can not use that full multiplier continuously for 1 second. On a Windows PC, there are hundreds of threads running at idle which frequently wake up both cores so the average multiplier will be less than 14. The 14 multi that Everest shows at idle is meaningless.

    That is true, is better to have 133 with TS, than 166 without it....

    I have been gaming in my R2 i5 at 133, and I have great results, I mostly only OC to edit video (it can save me a few minutes, a lot encoding to many videos)

    166mhz stable, no problems. Throttlestop makes all the difference though :D

    158MHz is my max stable clock, with ThrottleStop.

    Same here, 166MHz with ThrottleStop. Never blue screened or crashed yet (knock on wood)

    A poll would have been nice. Didn't think of it at the time. :)

    I'm happy to report that I can run at 160MHz stably right now. Probably could go higher but 160 seemed like a nice even number. I've been running SC2 and Source games with no CPU-related crashes at all.

    You forgot to ask about CPU steppings- there are 2: K0 and R0 (I think). Perhaps K0 OCs better because it's a newer stepping? Just something for you to consider should you try this survey again.

    How do I find out which stepping I have? Is it something that I can read in the BIOS or do I have to install something to see it?

    Try BFBC2 that will crash if the CPU OC is not stable.

    You can use CPUZ to check the stepping. Not that knowing will be any good since we don't know which stepping is better.

    I am able to do 166 stable. Tested with prime95 and throttlestop for 10 hours. CPU-Z says I have revision C2.
