      The ground-off chips are 4000-series (1970s design) CMOS? Obviously the 4000 series has been a very good series, but a design secret?

          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"...

          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...

          [RoG Ally] Fault in one of the onboard RAM chips. Any way to diagnose which?
          by Prott
          Hello dear badcappers!

          The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?

          Backstory:
          After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.

          If there is a way to narrow down which memory module is faulty it would make my life much...

          Is there a list of known dodgy ATI Radeon chips?
          by LukeDavis
          Hello again! (People are likely going to get tired of seeing posts from me lol)

          I'd like to try and compile a list of known bad AMD/ATI Chipsets and graphics processors.

          While I do not possess the knowledge of some of the brilliant minds on this forum, I can at least mention a few chips I've encountered as being troublesome.

          1. ATI 216-0752001 (RS880M/RX280M) found inside 2 HP laptops, one I've since deemed screwed, and swapped the board to an intel one, the other HP seems to be less hateful and runs fine.

          2. ATI Mobility Radeon X1600 and the...
