How to overclock aftermarket ram

HP Recommended
HP Pavilion Gaming Desktop 690-0019nv
Microsoft Windows 10 (64-bit)

Hello! last Christmas i upgraded from the stock GB 2666mhz single channel ram to 16 gigabytes corsair vengeance lpx dual channel  at 3000mhz but the dimms seem to run at stock ddr4 speeds (2133 mhz ) and its taking 2 gigabytes as "hardware reserved" ram (i have tried unticking the thing in msconfig but that do'sent seem to make a deference) . how do i make the dimms go to their stock speed again for max performance in-game?

Hello @Grigoris90 

 

Two issues here.

1. The 2GB ram allocation has been a problem with the AMD systems. HP has tried to get AMD to provide help with a fix, but it never came. HP did produce a bios update that helps with "some" of the allocation issue.The bios should be version F.41.

Download this file and run it. Do Not Have Anything Running during the install. Do Not turn off the machine during the update.  sp101891.exe

 

2.  HP PCs can only run at stock hardware speeds. Ram cannot be overclocked as the bios is locked down and cannot be changed. You must only install what is rated by your specs. The bios is defaulting the 3000MHz speed to the SPD fail-safe boot speed of 2133MHz and staying there when Windows boots.

If you wanted 16GB of memory, you would have to purchase new ram that matches the timings of the original stick to ensure stability.
