External HDD with world's largest cache
-
A while ago I was able to save a super socket 7 board from the landfill. It is a MSI MS5169 ver 2.1 with an Alladin V chipset. There is 512KB L2 cache onboard and the board has Chhsi caps. I tested the board with different AMD K6-2 processors and different PC133 memory modules. The board is equipped with the latest BIOS version.
The board is completely stable on 66FBS with the cache enabled. At 100fsb the board is only stable with the cache memory disabled. No memory errors. With the cache enabled at 100fsb I get errors in Memtest 86+ 4.xx and 5.xx
I therefore replaced... -
Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop.

After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:
Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during... -
Hey ya'll this is my first post on here. I recently aquired a used/broken 2019 mbp 16 a2141 with the 820-01700 board. Seller told me that the laptop needed a new lcd. However upon doing some troubleshooting i found out the lcd is fine.

If i connect and external monitor while its already on, nothing happens and no image is displayed on external. However if i restart or boot the machine while its plugged in, the external then works and a backlight is now visible on the laptop.... -

This device came in due to the screen flickering if you use the touchpad or external mouse. It will flicker black when this occurs. If you use the touchscreen, the behavior does not appear. Also, if connected to external monitor, the external monitor is not affected by the flickering. I did a good amount of research on this, and concluded that it is due to the display driver. HP does not offer Windows 11 drivers for this model so I got the replacement drivers direct from Intel. I installed them and the problem...
