    I saw this in someones sig.. How?!?!?! Using setfsb I couldn't get above 2.4. I would honestly be thrilled with 3.7(what my deskys amd x6 turbos to)
    Can someone tell me how to do it? Thanks!

    Yeah search for throttlestop and have a look around. You can manipulate the multipliers using it.

    Im just trying to get it as close to my desktop (X6 and gtx 590) as I can.
    Also is there an Alienware specific guide to this? I dont wanna fry something... bit more complex than desktop o/c

    If you see temps getting to high you can consider a repaste of the CPU.
    Concerning overclock possibilities you can post in one of those threads to get more help from members with the same chip as yours ;)
    Also bare in mind that not all components overclock the same so don't get disappointed if you don't reach a certain point.

    Good luck.

    L.E.: if you only want to OC the CPU play with the TDP and multipliers instead of the FSB.

    When you use TS you should have the fsb on the default 133mhz and overclock with the mulipliers

    No temps are reasonable... I am just sooo close to the goal but I cant find a setting in throttlestop to raise the fsb.. If I up a multi itll bsod

    You should try to get back your bclk at 133 and increase multi. to obtain 3.7Ghz you should run them at 28x133. You may need to overvolt a bit your cpu to make it stable at that frequency and expect temperatures to increase. Also go under TPL and increse the tdp/tdc. I keep mine at 95W tdp and 85A tdc.

    anyway i wouldn't keep it at that frequency on a daily use basis.

    Maybe the m18x with 2920xm factory overclocked to 4.0 ghz and dual amd 6990m is something you need to consider buying. 6990m is available in the UK atm.

    Nah... I will stick with my m17x as LOOOONG as I can.. I am not a fan of sandybridge... if anything I will wait for a dual gpu AMD APU laptop

    You can only increase the BCLK / bus speed if your bios lets you do this or if SetFSB works on your laptop. ThrottleStop is only for increasing the multiplier. Most users get their best overall results by using the default 133 MHz BCLK and then increasing the multiplier instead because this method results in less heat than increasing the BCLK does. Very nice results by the way. It didn't take you long to get ThrottleStop figured out. It's like steroids for the 920XM. :)

    Since we are talking about 920xm overclocking, I was wondering if I could get some feedback on my clocks.

    It appears my 920xm is power hungry to achieve the high clocks across all 4 cores....maybe this is normal, that's what I would like to find out.

    I find that if I set the TDP and TDC at 80/75 it sits at around 19x to 20x across all four cores. I need to really push the TDP and TDC up to 90 and above to get the higher multipliers of 22x and 23x.

    The problem with this is that my temps get quite high.....90 TDP and 85 TDC gets me 20x-21x but my temps start cracking 90 degrees.

    I have re pasted multiple times using Shin Etsu X23, and I am no beginner when it comes to applying thermal paste. I have also tried adjusting the screws on the heat sink whilst on, but it only got worse so I imagine it is making contact....maybe I have a hot 920xm?

    What TDP and TDC setting are people using to achieve 25x/26x across all fours? I don't want to go too high in terms of TDP and TDC because I also have two 5870m's that are overclocked as well.

    Once thing I have noticed is that the copper bottom of the heat sink looks as though it is wearing through?? I don't know how since i have probably only done a re paste only 4 times in the life of the lappy.

    Also, what is the purpose of the thermal pad on the CPU heat sink? It doesn't look like it makes contact with anything...

    I have attached some screenshots of Prime95 runs with 8 threads and 1 thread.

    Sorry to highjack this thread!

    You don't need 4ghz to equal your desktop power. Most likely 3.2 ghz.

    AMD is weak stuff.

    I'm curious about this as well...never bothered replacing it because I never really understood what it's purpose was :confused:

    Have you tried the "book mod"? By elevating the back I dropped the temperatures by ~10 degrees C. I have gotten the most out of my rig with TDP/TDC at 95/85 x27,27,26,25 and have been using these settings since posting the results a few months ago in the link that follows. The limiting factor now is power. I have tried to raise TDP/TDC to 100/85 but the rig will shut off immediately for want of current. I have OC'ed the GPU's to 800/1100. I am not overvolting at all.

    While playing The Witcher 2, the temps never exceed 83 C for the CPU and 75 and 78 C for the GPU's. I am maxed in all settings except ubersampling.

    The results of Crysis 2 are in the post below.

    3DMarkVantage with aforementioned settings in sig.

    If you havent already, elevate the back-end of your R2, youll be pleasantly surprised as to the significant drop in temps.

    http://forum.notebookreview.com/alienware-m17x/586490-ultimate-cooling-mod-end-all-cooling-mods.html

    Hopeful of M18x PSU compatibility.

    @Douse

    my results
    Dell M6500
    920xm oem @22x133
    TDP/TC 85/70

    3dmark06 test.

    logs from trottlestop

    It didn't maintain 22x ratio as you can see and temps are high.
    What I've already read you should run wprime 1.55 32m test to see if ratio isn't changed.
    During 1024m the ratio (always) falls down.

    I've got m6500 and there is a problem with fans. They turn the fastest gear very lately so the temps are high.

    Mk fien I did it. I bought an M18x.. with the dual 6990ms.. Was tired of tinkering with the m17x. Sold it for twice what I payed for it on Craigslist > :D

    The book trick is a good idea, but I use a NZXT Cryo LX cooler which would be more effective

    Your results are pretty much exactly what I am experiencing. I have my settings basically the same as you and my ratio hovers between 19 and 20.

    So my results are normal then, if not a little on the hot side. But this may be because I got unlucky with the chip and it runs a little hot.

    Thanks for your input guys!

    Hello guyz, Do i need to bump up core voltage by 75 or 150mv when OCing 920xm so much ? i mean 24@4Cores and 140fsb ?

    My idle temps are 35-41'C with IC Diamond 7 :)

    Thanks
