My RAM is set to 2100 by default. Changing it to 2800 works fine on 2933, sometimes it boots without issues and doesn’t crash in Windows 95, but occasionally it gets stuck in a booting loop before resetting back to 2100. At 3000 it always loops and resets to 2100. The voltage is correctly at 1.35, and other settings are already correct for the RAM. Should I stick with 2800?

Adjusted the SOC voltage to 1.175 to achieve 3200 CL 14 on my Flarex ram.
1.2 is the upper limit here.
This really aids in reaching higher ram clocks.
I’m unsure if this setting exists in your BIOS.
In my setup, using xmp instead of full manual settings works better.
Previously, I needed to rely on manual timings for a few months.
Raising the ram BOOT voltage to 1.4 might also assist with cold boot problems.
This differs from the standard ram voltage of 1.35.
I’m still not sure if this option is available in BIOS.
My Crosshair 6 offers so many BIOS settings it’s a bit overwhelming.
I tried starting with ram first for stability, then increased CPU speed to see what works best for me.
2933...

I adjusted the SOC voltage to 1.175 to achieve and maintain 3200 CL 14 on my Flarex ram.
1.2 is the maximum acceptable here.
This definitely aids in reaching higher ram clocks.
I’m unsure if this setting is available in your BIOS.
In my setup, I rely on xmp settings instead of full manual adjustments.
Previously, an earlier BIOS version required manual timings to reach this, but not recently.
Raising the ram BOOT voltage to 1.4 can also assist with cold boot problems.
This differs from the standard ram voltage, which is 1.35.
Again, I’m not sure if you offer this option in your BIOS.
My Crosshair 6 has so many BIOS settings it’s a bit overwhelming.
I found that starting with ram first and ensuring stability, then increasing CPU speed works best for me.
2933 might be your upper limit, likely around CAS 16 timings.
At 2800 you could achieve tighter settings.
Either way will significantly improve on 2100.

Hi, I'm having trouble locating the SOC voltage or RAM boot voltage, but 2933 works at C16 with some extra testing. Any advice for the CPU? Also, happy holidays!

It has restarted itself to 2100, which seems to be around 2800.

Hey everyone, the newest bios suggest 2933 can keep running smoothly under stress (95% pass), though after a few restarts it drops back to 2100. If you're curious, I went with 3800 at 1.2V for 4GHz @1.375V, but it overheated at 90°C—still better than what most people experience even with upgraded boards and cooling.
