Issue with P5P43TD PRO 1600Mhz RAM
Issue with P5P43TD PRO 1600Mhz RAM
Hello Everyone,
I’m facing an issue with my motherboard P5P43TD PRO. It’s quite outdated, but I’ve been using a 4GB Patriot Memory 2x2Gb RAM at 1600Mhz manually overclocked with a multiplier and bus speed of 7.5 x 400 MHz, achieving a core speed of 3000.0 MHz without any problems.
Last night, I purchased a second set of Corsair Dominator 2x2Gb RAM at the same frequency. However, these two new modules won’t boot. After rebooting and setting a safe frequency of 1066Mhz, overclocking failed with an error message. I tried to reset the BIOS without changes, then restarted the PC. Now everything works smoothly: RAM runs at 1600Mhz and the processor at 3.0GHz, no issues detected.
The problem only appears when I power off the PC; it functions normally once Windows is running. I’m puzzled as to why this happens from the start.
PS: If the RAMs are set to 1333Mhz, they still work even when the PC is turned off.
Do you have any suggestions on how to keep the RAM at 1600Mhz without needing a Windows restart? I’ve found some details from CPUZ that might help.
It is detailed in the manual that this component consists of four 240-pin DIMMs with a maximum capacity of 16 GB. It uses DDR3 memory at speeds up to 1600 MHz (with some variations). The memory is non-ECC and un-buffered, featuring a dual-channel architecture. When overclocking to 1600MHz, only one DIMM can be used per channel.
Well, I saw that in the manual as well, but thats nothing helped to me,
I have populated ona channel with 2x2 Corsair RAMs and the second channel 2x2 Patriot RAMs, so 4x2GB in total,
I do not understand why its working just fine when I restart PC from the windows and why its not working if I power on the PC, why its not working from the begining correctly, here is completely list of the RAMs what I have installed

Mixing ram is always a risky move. It could possibly succeed, but it's unlikely. None of the JEDEC profiles align, so the BIOS is searching for settings that fit both types of modules. As mentioned earlier, achieving 1600mhz requires using two sticks installed together.
