    4 hours is not enough with high humidity. I do at least 6 hours at 125°C (both the board and the chip). The required time will depend on the humidity level, how long it's been exposed to humidity and the package of the chip. The longer the better… If you popcorn a chip then you now you'll have to bake for at least a couple of hours more.

        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"...

        Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul
        by karatzdi
        Hello,

        I know some might say... just buy another one. Sell it as parts..!

        So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
        Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

        Spent some time downloading the Service...

        WSON8 NEW Bios Chips READ, ERROR, ETC.
        by feherhollo
        Hi,
        I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
        I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green

        For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct...

        NVidia bumpgate
        by piernov
        Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
        Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


        May complete this post at a later date with more details.
        Basically issue is a combination of thermal dissipation of the chip with hotspot,...

        HP Probook 450 G7 DA0X8MMB6D0 Power-up problem
        by badcapjerboard
        This is a spill that I got stuck on and am hoping for help.
        I originally cleaned corrosion from the area between the cpu and back edge of the board. The charging light goes on white with 5-6 amber flashes then off when plugged in. No difference with battery only or together.
        I had main power rail and 5v and 3v rails.
        I noticed q402 in the spill area wasn't getting voltage and figured out r468 was missing with a damaged pad. I eventually managed to scratch out a trace next to that pad and solder a longer resistor and q402 had 3.3 input.
        pu9200 is not outputting 1v. It has...
