Congratulations and thanks for the mention. I haven't been on the forum in a long while.

I must get round to doing this on my M14x. Change the stock stuff that Dell uses (thermal pads basically) to Noctua's stuff that I got with my NH-D14 Heatsink/Fan for my i7 2600K system, which is overclocked at 4.9GHz currently (1.44v). I expect I'd see some temperature drop, which is helpful in a laptop. Just a matter of getting the courage to take the laptop to bits that much.

Your method is useful for those who are either BIOS inexperienced (with the unlocked version) or to those who don't have an unlocked BIOS version. This method also disables the option 'Turbo PWR Limit MSR Lock' as mentioned in my first post, permanently (unless re-enabled manually in the BIOS). Unfortunately it doesn't solve the problem of the long TPL (wattage) having to be set everytime I reboot, despite the BIOS having the setting of 99. Understandably a limiation of the BIOS and non-XM. If I had the confidence of hex editing a BIOS I would try and do so, but for now I'll just stick to manually changing the long TPL value every reboot. Mind you, if I stay at 3 cores + HT + Turbo with a BCLK of 105.40MHz I shouldn't need to change the long TPL limit to more than 48W (which it sets it to every reboot) as the power consumed under full load is around 41W-42W.

I see, thanks. I might try and tighten the memory timings and increase memory voltage slightly to accomodate this. I'm familiar with the Sandybridge overclocking limits with desktop overclocking (I have an i7 2600K clocked at 4.9GHz), some of that should apply to this as it's still Sandybridge (just not unlocked multipliers and CPU voltage). As long as I don't go beyond 1.60v on the memory all should be fine, the maximum option offered is 1.65v anyway, but 1.60v would be my limit. Also I've tried playing around with getting my long TPL setting to be permanent but sadly no matter what I do it reverts back to 48w, I can however change this every reboot in XTU or TS manually, just a pity there's no software available to automatically load profiles or settings for this option.

I see, interesting. I was just wondering, like my ASUS P8Z68-V Pro system, whether the BIOS has a failsafe implementation. What I mean is, say I set the memory clock to something not supported and the system won't boot, will I be able to recover it (I have enabled some unlocked setting called 'watchdog' which was supposed to detect POST freezes and set default on next boot if so, not sure if it relates to that though) without taking the system apart and removing the CMOS battery for a moment?

I see. Well I've been looking around for alternatives to keeping the new TPL settings permanent, rather than me opening ThrottleStop every reboot and reapplying them. I've found Intel XTU, which seems to work, and plays with the BIOS values too. With Intel XTU I've also been able to exceed the BCLK limit of 103.09 in the BIOS, I'm testing at 105.60 currently (shows as 105.50 however). Also, instead of disabling HT or turbo I'm trying out 3 cores with HT and turbo enabled. I'm achieving around 3165MHz constantly at a peak temperature of 87C at the moment, no downclocks or throttles due to the previous TPL settings and restrictions. The system appears to be stable. Sadly XTU doesn't appear to be able to save the BCLK permanently, unlike the TPL settings, though every reboot once it reloads the XTU software I get 'not all settings could be applied' and sometimes have to re-apply the TPL settings again. UPDATE: It would seem the highest BCLK my laptop will run at is 105.80MHz, still better than 103.09MHz.

Hi all, I haven't been around here for a while, and if there is already a topic about this or somehow it's finally become available without the unlocked BIOS A05 and changing a setting the unlocked BIOS A05 then please feel free to disregard and remove this thread. So, basically I'm going to explain how you can make your processor not drop down multipliers after a short time of maximum power, as such happened in the past (http://forum.techinferno.com/alienware-m14x/866-m14x-questions-about-cpu-temp-calling-aw-2.html#post10035). After you've applied the steps mentioned in this guide you should find, like I have, that your processor multiplier remains fairly constant as if it was just beginning to be stressed. For example, my i7 2720QM starts at a multiplier of roughly x30, and in less than a minute it was originally dropping down to roughly x26 due to turbo power limits (TPL). Now it's remaining at roughly x30 for any length of time (lasted for the 352.404s test I did with 8 threads in TS Bench). One word of warning before you begin, you must have the unlocked BIOS, preferably A05 but probably can be a different version. You must also be aware of the fact that without a cooling pad your laptop will likely throttle or shutdown before the CPU stress test (which lasted little more than 5 minutes) has completed. I am using a Coolmaster something, can't remember the name of it, suffice to say it is efficient and has three fans. Despite having this my CPU peaked at a temperature of 94C, and averaged at a temperature of 92C on the hottest core. You could reduce this temperature by disabling hyperthreading of course (if you have an i7). This test was also performed on the default BCLK (which registers as 99.7MHz on my laptop), I dread to think what would happen if I increased it with the TPL settings much higher/disabled. Anyway, lets begin. - Go into the BIOS (if you have the unlocked BIOS that is) - Go to 7th tab which should be 'Power' - In there go to 'Advanced CPU Control' - In that scroll down until you find the option named 'Turbo PWR Limit MSR Lock', by default this is enabled, simply disable it Save settings and reboot, remember to make sure your long and short duration limits are setup to their maximum BIOS values. Once you have rebooted, you will need something like ThrottleStop (I don't know of alternatives to hand, suggestions welcome). Open ThrottleStop, go to the TPL button and then you should be able to disable the second limit,and increase both values of the limits. I was unable to do this with the locked BIOS and unchanged hidden BIOS setting. This will allow your CPU multiplier to remain at almost the same equivalent of the TRL settings depending on the number of threads running. Like this thread/guide? Give feedback or 'like' it.

I have plenty of voltage and clock, or other oc options in the BIOS, too many to realistically list. The motherboard is an Asrock Z68 Pro3-M. I did read a few forum threads elsewhere about making the voltage to the memory higher than 1.65v is considered dangerous for the CPU and that any such RAM requiring that amount of volt either needs to be changed or possibly have a lower than advertised speed set. If you can be more specific as to what section you want to know what options there are, e.g. OCing, I'll provide them. My memory is more or less this, which I've had in my i7 920 system for a long time: Corsair Twin3X 4GB DDR3 (2x2048MB) TW3X4G1600C9DHX 1600MHz [TW3X4G1600C9DHX] from Overclock.co.uk.

Hi all, The memory I have, Corsair XMS3 DHX 4GB (2x2GB) DDR3 1600C9DHX, is rated 1.8v, however I understand that the memory ideally shouldn't be run at that voltage as the Sandybridge architecture wasn't designed to have the memory controller run at that voltage. Unfortunately the 'auto' clock setting for the memory has chosen 1066 at an 'auto' voltage of 1.575v. I would like to know whether I'm going to need to put together some cash for a new set of 4GB memory which is rated at lower voltage with equivalent clock, or if anyone has some other advise? I haven't overclocked any components yet. I have an i7 2600K cooled by a Corsair H70. Top temperatures have reached around 60C under full load using programs such as wPrime on 8 threads, idle temperatures are about 25-30C. Motherboard is an Asrock Z68 Pro3-M. Power supply isn't anything special right now, waiting to get a better one as my previous Enermax Galaxy 1000W has decided to give up after being switched to this new system from my old one (i7 920), simply two beeps every second and a red light which indicates a short circuit or overload, but I have tried cleaning it out, testing different outlets and kettle leads, and using the paper clip method of testing a PSU on its own, sadly nothing makes it come to life for more than a second. Anyway back to the specs, it's 750W with dual 12v rails provided 20A each (I believe it was). No GPU installed right now, using the onboard GPU on the CPU for now.

Hi, One thing I'll point out that's the biggest waste of money for gaming is the 3GB version of the GT555m, you don't need it, go with the 1GB one, it's more than adequate for games of this day and age still. With that money saved, you could look at getting the i7 2720QM instead (for CPU) as some games generally use CPU and GPU power quite intensively, but really the GPU is the bottleneck of the M14x (not to say that it's not good though, overclock it and it's even better!). If you're satisfied with not having a high res screen then the screen is fine, you could always connect it to an external monitor or projector anyway. The amount of RAM is sufficient, I have 8GB but 6-8 is ample. Apart from that, that's my advice, hope it's helpful. I run games like TF2, GTA IV, the latest COD, all fine, GTA IV has a slight issue with the GPU information though, but plays quite well imo. Welcome to TI by the way.

I don't have any of those games installed, however I did try Star Trek Online which uses between 40-60% CPU most of the time and the multiplier remained at 30.00, sometimes dropping to the 29's for a second or two. Temperatures (maximum) today are slightly up a bit again, in the high 80's (86-89C).

Assuming I've set the BIOS up correctly to begin with, that is up to the fused value for the long limits and 99 for the short limit, here are the wPrime results. Four Threads (default): - Started at 2996~ (x30~) - Wavers between 2910-2990 (x29-x30) after 100 seconds - 455 seconds took for test to complete on four threads Eight Threads (as my CPU offers eight): - Started at 2910-2990 (x29-x30) wavering - 2625-2696 (x26-x27) after 50 seconds - 2625-2630 (x26) after 70 seconds - 335 seconds took for test to complete on eight threads (!! Bear in mind the second test was performed quickly after the first, and so initial starting results may have differed if I had started it from a normal idle temp !!)

Another update today, after allowing more time for the thermal paste to settle. As you can see by that image, it looks like temperatures both idle and max are much improved. I ran Star Trek Online, wPrime (1024M twice), and the CPU overclocking is just in the sense of modified turbo limits in the BIOS, I was able to maintain just over a stable 2.73GHz under wPrime 1024M tests with an average temperature, in celsius, in the 70's across all processor cores.

Here's an update. The technician has been today, took him at most 30 minutes to replace the heatsink and repaste the CPU, quite fast! He said allow it at least 2 days to settle (understandable), and keep an eye on the temperature of the CPU to see if it reaches similarly high temperatures, if it does call Dell and we'll replace the motherboard as it could be a faulty chip. Excellent customer service and warranty! So, after a small 30 minute game of intense battle fighting the Klingons, and winning 1st place in the fleet action (of course ), here are my latest maximum temperatures from ThrottleStop. Given the fact my room is air conditioned to maintain 21C, there's a Cooler Master NotePal U3 with fans positioned under all vent locations (3rd being at the middle front where there's a very small vent), fans of course running full speed, I still find it hard to believe these temperatures can be called sane, but perhaps I'm wrong. I am tempted to try it without the NotePal underneath it, flat on the desk, to see the temperatures then. Opinions?

Well that was a quick phone call, after being transferred to the right department. The troubleshooting process was minimal, compared to most companies I've dealt with, impressive. Sadly I wasn't as lucky as some others, I was offered a technician to replace the heatsink/thermal paste instead of a possible motherboard change, oh well, fingers crossed I won't get any issues regarding the half broken clip if he/she notices.
