DISCLAIMER: I accept no responsibility for your actions based on this guide. What you do is from your own free will, this mod is not forced upon you. Be aware if you do commit to this mod, you will be voiding warranty, no two ways about it. Do not post about how to retain the warranty with a pinmod, it is fraudulent behaviour. What is it? The pinmod consists of disconnecting the TME pin from the PLL, which is in this case, PIN 14. By disconnecting PIN 14, it is possible to unlock the PLL, allowing it to be controlled by SetFSB for further overclocking. What are the gains? You get out what you put in really. Add 30% extra clockspeed, you'll get 30% extra performance in applications that are bottlenecked by the CPU. Who can do it? As of now, I know there are 2 types of PLL used in the M11x: the ICS 9LPRS387 and the SLG 8SP556V. This guide only supports the ICS PLL for now. All M11x owners can attempt this mod, whether they have the SU 7300 or SU 4100. What sort of overclock should I expect? Overclocking potential is different for everyone. Your Mileage May Vary. Expect 1.9-2Ghz with a decent chip. How can I tell which PLL I have? To identify which PLL you have, use SetFSB and select the PLL “ICS9LPRS365BGLF” and select “Get FSB”. If SetFSB returns with “PLL ID error”, it means you do not have the ICS9LPRS387 and very likely have the SLG8SP556V PLL. To confirm if you have the SLG PLL, select the “SLG8SP513V” and click “Get FSB”. If SetFSB displays the FSB values correctly, (IE: 266mhz if Overclock mode is enabled in BIOS) then you definitely have the SLG PLL. I have an SLG PLL, how can I do this mod? You can't as the SLG PLL is not programmable. However, it is still possible to overclock to 1.73/1.8/1.95/2/2.16 Ghz using the FSLx mod. All the clockspeeds except 1.73Ghz are hard mods and require soldering fine pins. Do not use a conductive pen to connect pins, it will not work, you will get a brick with no warranty. A guide to get to 2Ghz has been provided by Nando4. 1.73Ghz is still 8.4% faster then 1.6Ghz. What are the advantages and disadvantages of doing this mod? Advantages: 1. It's faster: I gained more speed then with the system's Overclock mode. It's pretty much a low end full voltage Core 2 Duo now. At 2Ghz, it is 10% slower then the i5 TS 166. 2. It's possible to use the M11x as it was sold: at 1.73Ghz with SpeedStep. 3. It doesn't run any hotter. 4. Negliable battery life loss: I only found the system to be discharging 800mW more than stock. Disadvantages: 1. Cannot clock down: Once SetFSB clocks the CPU up, it cannot clock back down to stock without crashing. On another M11x, I found I could clock down perfectly. Must be just my M11x. 2. Not automated: Must keep using SetFSB or buy the shareware version to automate the overclock during startup. I haven’t done anything fancy like setting up GRUB to set the overclock before Windows boots. 3. When the system crashes, it will not boot. Rather, it will boot with a black screen saying “Operating system not found”. It requires a hard reset by pressing the power button. 4. Warranty will be void. 5a. Needs a good VID chip to clock further (Only applies if Overclock mode is enabled): The CPU is still receiving .9v with SetFSB, so obviously, one must have a good quality chip to keep increasing clocks. In my experience with desktop Core 2 Duos, a lower VID meant it could clock further at the same voltage so I think it applies here too. YMMV. 5b. Needs good RAM to keep clocking up (Only applies if Overclock mode is disabled): The chipset sets the RAM divider to 1:2 during Stock 1.3Ghz speed. By default, the M11x R1 is shipped with 1066mhz RAM with timings of 6-6-6-15 (457mhz) being applied. This means if the FSB is increased beyond 228mhz, the RAM is being overclocked and YMMV. I can't comment on using Thaiphoon Burner or CAS7 RAM as I haven't been able to boot with it. I only got to 293mhz with 6-6-6-15 timings. Part 1, Unlocking TME: I have an ICS PLL, how can I do this mod? 1. Take a screenshot of the SetFSB screen in Windows with the ICS9LPRS365BGLF PLL. You’ll need it later. 2. Disassemble the M11x motherboard. You may or may not need to disconnect the display. 3. a. Solder a 10k resistor to PIN 14 and connecting it to Ground. Ground can be any screwhole edge. b.OMIT EASY MOD -Cutting pin 14 - DOES NOT WORK RELIABLY 4. Reassemble the M11x. 5. Boot up the M11x and login to Windows. If your M11x refuses to boot and has a beep sequence of 7 short beeps, it means you physically connected adjacent pins to Pin 14. "Separate" the connected pins. 6. Open SetFSB and check Byte 9, Bit 6 (pictured). It should show 0 meaning TME is unlocked and ready for overclock. If it doesn’t you didn’t cut the pin well enough, try again. If TME is unlocked, you are ready to overclock. Do not pull the sliders on SetFSB as it will not work, only freeze your system. We must program the PLL to be covered in the next part. Part 2: Programming the PLL. I have unlocked TME. Now what? Use SetPLL. Tip: Enabling Overclock mode in BIOS can allow the RAM to be eliminated as a limiter to the overclock. It will isolate vcore and the chipset. That’s about it really. CPU overclocking unlocked and ready for stability tests. Cool story bro, I done that and I want moar speed: Consider making a DIY ViDock. Get a R2 Do a volt mod if you’re limited by vcore. Get better RAM if limited by RAM. Wait for a R3 and buy it Thanks to Nando4 for discovering how to unlock TME, finding out how to do the FSLx mod for SLG owners and for fixing the table. Thanks to rpg-XPS for finding the essential datasheet. Thanks to Dufus for posting how to program the PLL. Thanks to bavman for finding the SLG datasheet. Thanks to some guy for confirming the FSLx mod works.
