How do I underclock my ram? Ratio where I was stating that it was already 1:1 according to memset program. I need to underclock RAM to boost base clock to. Underclocking RAM? Sign in to follow this. So what I was wondering is if I can underclock the ddr4 2400 to work with my motherboard. Solved How do I underclock my ram? How to underclock ram's voltage from 1.5v to 1.35v? Solved How do I underclock/undervolt an fx6300 on a Gigabyte GA-LMT78-S2?

For IBM/Lenovo ThinkPad laptop enthusiasts. Blog posts are encouraged. If your post does not appear in the queue, it's because of the stupid spam filter. Use the link to 'message the moderators' below to tell them. Tips: • When buying a used ThinkPad, remember to check that the BIOS is not locked with a supervisor's password and that Computrace is not enabled and activated. • When buying a new ThinkPad, consider taking the IPS screen option if possible, as it doesn't cost much.

Not only will it have better brightness, colour, contrast and viewing angles - you will most probably more than make up the investment when selling it. Corporate bulk purchasers don't usually go for it.

() • The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. A can of compressed air may be useful too, and a bottle of isopropyl alcohol and cotton buds are good for cleaning, but not on the screen.

Thank you for taking time to answer: Remove all batteries and power supply, unplug CMOS battery and live it for several hours. Lenovo's BIOS remembers hardware component settings and this trick may help. I have tried this, but to no success.

Do you have Intel AMT firmware updated? I don't know if I have it update or not. How would I go about to find this out? [It seems as if BIOS display version of firmware. Will check it out]. If I don't have it - can I install it the same way (through a bootable ISO put on a USB stick) as I do with the BIOS update?

Important since I'm using Linux. OP of the thread that SudoNow referenced here. While it is possible to modify the SPD data on the module, it's not really easy and will require a handful of tools, software and equipment to accomplish. In some recent research, I've found a method of using an arduino/raspi along with a SODIMM-->DIMM converter board to read/possibly modify the SPD EEPROM on the module to change it's speed (Down to 1866 as it's the next step down from 2133 according to JEDEC standard). Wheelman Crack Pc. I say possibly modify, because some modules, while they have an EEPROM (Electrically-Erasable-Programmable-Read-Only-Memory), they have a write protect fuse set so that you can read out the contents, but cannot write them back to the EEPROM. At that point, it's either give it up, or replace the EEPROM chip with a fresh blank chip that doesn't have the write protect enabled. These G.Skill modules, and most of the DDR3 modules I have around have impossibly fine pitch SOIC-8 type packages for the EEPROM.

It's damn near impossible for the home-gamer to solder these chips. I've ordered a handful of those SODIMM-->DIMM modules from China (the rest of the stuff I need, I have), and when they arrive, I'm planning on having a look at the SPD data and see if I can modify it to clock them down to 1866 and see what happens. And if that works, I may just do some playing around with the SPD data and see if it's simply the memory speed, or if the 2133Mhz profile has some timings or init data that doesn't play nice with the T4x0 machines. Forgot to address some of the other questions.

As for why the BIOS won't automatically underclock it, it may be that there is config/init data the system doesn't like when it reads it out, and it cannot configure the memory in that slot (Both slots when running both @ 2133, so the system cannot come up). When a compatible module is installed, it's using it's SPD data to initialize the other module and running it at the speed/timings on the good module. This would be why the system is dead with 2x2133mhz modules, but is OK with 1x2133mhz and 1x1600mhz modules.
