    Default [Guide] Overclocking the 2920XM/2960XM CPUs in the M17x R3 with/without Modded bios.

    @@@@@@@@@@@@@@@@@@@

    Note from NBR Moderation Team -

    BIOS Modifications, VBIOS Modifications and other system level tweaks
    can potentially cause damage to your system. Be aware of this before
    blindly flashing.

    If you brick your system or cause damage, chances are very high that
    your warranty will be useless.

    Please note: If using the Dell stock system BIOS to overclock, the options within the
    Performace settings section of the BIOS will not void your system warranty. It is only with
    third party modified BIOS use where you start to enter 'questionable' areas.

    Know what you are doing, you are responsible for your actions.

    @@@@@@@@@@@@@@@@@@@




    So hey guys, after weeks of research and conversing with the experts over at the M18x forums. I have finalized a straightforward enough method to unlock your CPU potential.

    I have split this into 3 sections. They have an order of hierarchy; meaning that Section 1 applies to all CPUs even the non-XM ones, Section 2 applies to users with XM CPUs and Section 3 applies to users with the XM CPU and modded A08 bios.

    Pre-requisites: I'm not going to post links, these are easy enough to find on your own. If you don't know what Google search is, you don't deserve to be reading my guide.

    Dell A08 bios - Be up to date
    An XM CPU - You need these to progress onto Section 2
    ThrottleStop - Doesn't really do much in the way of tweaking things but is a very good monitor.
    Intel Extreme Tuning Utility 2.1 - For manipulating multipliers.
    A decent amount of time and balls - This process takes a while and the second one is self explanatory
    Optional modded A08 bios - For the hardcore users.

    Overclocking the XM CPU creates masses amounts of heat. And I mean LOTS! Be prepared to see temperatures upwards of 90C. I am not responsible for burnt CPUs, motherboards, chassis, burgers or anything else. Do this at your own risk. I'm only providing you with a method not an obligation.

    Right so now you have all these things, we can progress

    Section 1
    First off, we need you to have your bios ready. Be it the modded one or the ordinary one. So boot into the bios and you will see an Advanced tab (modded bios users this is the first Advanced tab).



    What I need you all to do is to enable "Override Turbo Settings". When that is done, some more option will come out. You need to set them to:

    Long Duration PWR limit [99]
    Long Duration TimeWindow [56]
    Short Duration PWR Limit [Enabled]
    Short Duration PWR Limit [99]

    After you've set that, press F10, exit saving changes. Boot into windows. Open up ThrottleStop and click TPL. In the window you will see that your settings haven't quite been put it. If the "Turbo Time Limit" reads 56, it worked, as Alienware's default is 28.

    Now to achieve the unlocked state:

    Open up Intel XTU. There will be an index on the left, click on "Processor" under Manual Tuning. Scroll to the bottom. You will see sliders for the multipliers. This will be greyed out for non-XM users. Don't touch them yet, we will deal with this in Section 2. Above that however are sliders for the Turbo Boost Power. Slide these all the way to 99w. It will prompt a reboot. Do so.

    When booted back into windows, open up ThrottleStop again and you will see that the 99/99w have been enabled We did this because without doing so, the TDPs would be locked for the XM CPUs. But doing so also unlocks them for non-XM users. Win!

    Sometimes this doesn't work. If XTU doesn't prompt a reboot after you set the new TBP, click on TPL in ThrottleStop. it should register the changes immediately. You must then hit OK, MUST. Then reboot. Settings should stick now.

    Section 2
    So now you have your shiny XM CPU, you want to get it nice and quick. Well fear not for I can help you there.

    So a good place to start is at 4Ghz. Yep you heard correct; you got an XM CPU, it turbos at around 3.something so just take that to 4 and you'll be well and kicking.

    Open up iXTU, and go to the Multiplier bit we saw before. Raise those to 40x an all cores. Now, drop the Long Duration Power slider (the one on top) to 80w. Keep the Short Power one at 99w.

    When clicking apply, it will prompt a reboot. When this happens before it completes post, enter the bios and set the "Long PWR Limit" to 80. We need to do this as it seems that the bios has the last say. I'm not even sure if changing the power in the software makes a difference. I ran a benchmark once with the bios at default and changed the power to 80/99 in both ThrottleStop and iXTU and it didn't work. Still throttling so to avoid throttling, you need to set the power in the actual bios.

    So after you've restarted, you will be happily gliding along at 4Ghz. Simple! In my ThrottleStop, the TPL still read 99/99 when I did this. My guess is that there is some kind of bios override so that reading is wrong. I changed it to 80/99 because I'm OCD Remember to also change your TRL's in Throttlestop or else everything would be limited by it. Run a benchmark such as wPrime. Remember to change the Advanced Settings to make it run on 8 threads. The 32m test should be around 6.something seconds. Have ThrottleStop open when doing a 1024m test to see if the 40.00x multi stays for the whole run. BEWARE, running the 1024m test will raise your temp significantly.

    So now your shiny new XM CPU's potential has been utilised. If you want anything higher than 4Ghz, you will need to consult Section 3 when I finish it.

    Found this but its saying the service is not started. Checking BIOS settings because I installed it before your guide.

    Ok, make sure you have .Net 3.5 with all updates. What is the problem exactly?

    NVM my BIOS settings got reset to default. It worked after I corrected it. I've got modded A08 so I had to kinda tinker around.

    Definately did something I got about 3.7 off a quick test single core.

    EDIT: now I've gotten 4Ghz. and 3.6ish with all 8 cores

    Ok I'll update the guide soon with Section 3 all about the modded bios such as currents and c-states.

    What thermal paste you using lol I'm throttling all over the place. Its fairly stable with a core or two. I've had it up to 4.2Ghz now. Not to argue it still only drops to 3.5-3.6 under full 8 core load.

    I'm using IC Diamond 7 which is suppose to be one of the better ones. AC MX-4 is what i'll be buying next...heard that one is better

    I am very happy with my MX-4. It gets my recommendation.
