hp 745 G3 after flashiing Bios ( 2 chips 64&128) the laptop stop on Hp logo

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"... -
I don't know if anyone here has experience with Japanese slot (pachislo) machines, but I sure hope so. I bought this machine last week in semi-working order. It would play and the reels would spin, but the stop buttons would not stop them at all. I found that the high-frequency filtering tantalum capacitor was bad on the reel stop board, along with the fuse being blown. I replaced the fuse and removed the capacitor. I haven't replaced the cap yet because I didn't have one on hand, but it's not necessary for the operation of the machine.
The issue now is the Stop buttons are intermittently... -
Hi all,

Im looking for a tool to change the bios logo.

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... -
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,...
