Alienware Area51m R1 RU.efi edit to run RAM at higher speeds

[amirhesamsadeghpour]

Out of all the BIOS versions I tested, BIOS 1.7.3 delivered the best memory frequency and timing results.

 

Using very ordinary Samsung DDR4-2666 memory modules, I was able to overclock them to 2933 MHz with timings of CL17

1.7.3 nice 👌

I was on 1.3.2 but updated to 1.9.3 to try and fix the bad BIOS handshake with the AGA 5080 RTX. No improvement.

I have 3200Mhz 128GB Samsung DDR4.

 

It's running at 2933Mhz now using default settings (only changed frequency in bios).

 

Is there any way to try 3200mhz? I don't care about timings right now, just want to try 3200mhz and see if it works.

"0C80 = 3200, 0xA63 as 80 and 0xA64 as 0C"

What exactly is your issue with the 5080? Maybe we can make some changes using RU.

By default the frequency is 2400. My RAM is 2666 MHz and it is stable up to 2933, which is why I didn’t push it higher. Send me a screenshot from the Memory tab in CPU-Z so I can check your RAM situation and guide you.
