  1. Maybe something went wrong during the flash.

    Have you tried removing your RAM(s) stick(s) and trying one by one, and also, clean then with a white rubber very gently.

     

    If not, there should be some key combo that should enable rescue BIOS flash, that will read the bios from a usb stick with a specific file name, sorry for being vague, I dont know a lot about Lenovo.

    You have to deal that with him, but anyway it will be cheaper than on Ebay. Just check prices on taobao, you'll understand what's the real market price of those products in China. Obviously, Ebay prices are much higher.

     

    I changed CPU today, I upgraded to a 3940XM. It's running quite fine while gaming, but in fact even if I can improve Physics score a little when benchmarking, I'm still bottlenecked by 2 things: the 240W PSU which is causing power limit throttling when CPU and GPU are at high load, and air cooling which can't barely deal with such heat to cool down. So next step is setting up a dual 240W PSU, and if it can fix power limit issue then I'll work on the final mod, which could be a full watercooling for CPU, GPU and VRMs. I ordered all components for the dual PSU mod, it should be here in a few weeks.

     

    Taobao prices after adding shipping and Paypal fees end in the 750-800€, on eBay its "only" around 100€, and one or another will be hit hard by customs in my country, so extra 23% VAT over all that :(

    Lets wait for volta to come out to see if Pascal gets cheaper lol.

  3. Disassemble the laptop, clean the heatsink with a brush or compressed air while holding the fan still, then clean the cpu, gpu and the heatsink faces with napkins and alchool, apply a thin line of thermal paste in the cpu because is very rectangular and a pea sized drop in the gpu.

     

    User Artic MX4 or Kryonaut.

     

    Toshiba is already throttling is CPU to 30Watts TDP via current limit, so your best bet is to undervolt it, it will be cooler and you will gain 100-200Mhz under load.

     

    I have a P50-A and I spent a couple hours to remove the stupid current limitation :

     

    But I'm using LiquidUltra on mine because the heatsink is all cooper all I did was apply nail polish over the exposed caps and test pads on the cpu/gpu and applied the LiquidUltra.

  4. There are two kinds of M.2 SSD's, there are the PCIe based ones, those can be either NVMe or AHCI, NVMe ones are the fastest, AHCI are a bit slower(mainly IOP's, and are more or less phased out).

    Then there are m.2 SATA SSD's, those use the regular SATA interface and will be as fast/slow as a regular 2.5inch SATA SSD.

    If you use a M.2 SATA to 2.5inch SATA interface you are just wasting money on the converter and more money on the SSD because M.2 SATA SSD's are kinda rare(the most recent one's are MX300's) and they will offer exactly the same speed as a 2.5inch drive will ever deliver.

     

    Your laptop doesnt support m.2 PCIe SSD's, so just get a big 2.5inch SATA SSD and be happy.

    Also, update your BIOS and all your drivers, and do a clean install of Windows, NEVER clone an install from an HDD to an SSD.

     

  5. Interesting, thanks for the links, but the laptop was already returned to my friend(the owner), I found a B950, and after going into Device Manager and removing the CPU and rebooting it recognized the new CPU clock speed, added 4GB of RAM and a new 1TB HGST HDD, clean install of Windows and a cleaned heatsink, its ready for another couple years of Facebook and Spotify, if he ever wants I will try that, because I have a dozen i7's laying around from broken laptops that are just gattering dust in my desk :(

  6. A big part of the better sound is bigger sound chambers for each speaker, aka the enclosure, and if you swap only  the speakers and keep the original Clevo enclosures it will sound the same..

     

    I find funny that what as a couple years ago a normal speaker is called a sub, my Asus N53SM had speakers in the 5cm diameter range, bigger than the "sub" in mi MSI and ROG G750 lel..

    The sub will need an extra amplified output that is also filtered/EQ'ed to just emit lower frequencies so you cant just drop a sub into a laptop that doesn't have one.

  7. Good evening, is there a way to disable what is supposed to be the Intel Anti Theft protection in a Toshiba Pro C850 laptop, the stock CPU is a Celeron B830, and I've an i7-2630qm laying around, as expect, works OK, temps are great, but as expected after 30 minutes the laptop just shuts down, is there a way to disable this kind of stupid limitation?

     

    Best regards.

     

    EDIT:

     

    Well, going a bit easier than expected..

    The update BIOS contains the ME_FW already in a separated file, so I opened it up with FITC 8.1.10.1286 and Intel Anti-Theft is disabled and I can't see any obvious timeout values or timers/watchdogs :/

    Any ideias if I'm doing things wrong, or is it some magic bit in the clock/ICC profile that disables this thingy?

     

    Attached is the ME_FW if anyone wants to take a peek.

     

    Thanks afain.
