    New TME mod idea.

    TME=Time Management Execute.
    This is a function on some PLL chips that allows the BIOS to set a hard upper limit to the FSB. A high signal during POST sets the limit to a value that's slected on other pins of the PLL.
    A mod on older computer was to pull down the TME signal with a resistor to ground. Later PLL chips multiplexed a 33MHz output to the PCI bus on the TME pin to defeat this.
    My thinking is if you put a diode to allow the PCI frequency out you should be able to put a parallel resistor on the input to unlock the TME limit. Resistor in,diode out.
    Do you think this would work?
    What specific diode or resistor parts would be needed for this?
    I think I can handle the soldering for this myself.

    who knows, depends on the PLL chip and how exactly it's prohibiting overclock...

      Truste Mode Execute is the another term for this. I've seen it called the other also. Maybe different chip vendors.

        Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
        by ugamazing
        I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

        Dell 2209WA - power supply - Fusible Resistor replacement
        by jinu_j
        Hi

        I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

        1. FR950 - blown fusible resistor - 0.2 Ohm 1W
        2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
        3. R835 - Blown Resistor - 20KOhm SMD resistor
        4. D930 - Shorted Schottkey Diode...

        Need help to replace burned resistor in 350w atx psu
        by mikey5791
        Hi to all forum members,

        Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
        The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

        Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
        Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

        Can a resistor lose resistance after hot air?
        by MidnightRoller
        I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.

        I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors...

        What resistor ohm will work better to repair this waterpik?
        by artvandalai
        The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y
