Getting memory to 3600MHz
Getting memory to 3600MHz
Hello, I own Corsair Vengeance Pro RGB Memory. I initially had a 16GB configuration (two 8GB modules) and easily reached 3600MHz at CAS 18. I later added another 16GB (four 8GB modules), but it can no longer sustain 3600MHz (that’s completely understandable). I was able to push it up to 3200MHz. I experimented with adjusting the voltages (though I’m not sure which ones) but still couldn’t exceed 3200MHz. The 3200MHz setting is stable and has held without crashes so far. Is there a way to reach 3600MHz? If lowering CAS latency could help performance, feel free to suggest it. Thanks ahead!
The IMC on the CPU or the new RAM sticks aren't working. I recommend trying the RAM sticks separately to check if they can start up at 3600 MHz, as your previous setup might have worked.
for voltages soc <= 1.2v vddp <= 1.1v vddg <= 1.1 (5?) v are typically maximum 24/7 operation. This suggests the dimmable voltage is likely best managed by the current XMP settings, as higher voltages can cause degradation in some chips. The 3600 cl18 model is already quite unstable, so it might be more efficient to adjust timing at 3200 if you haven't done so yet. Consider testing frequencies between 3200 and 3600.
After checking more closely, the RAM units aren’t identical. Only one digit in the model number differs. Still, I reached a stable speed of 3400MHz, which is acceptable. The issue stemmed from Ryzen Master adjusting my CAS latency to 15, causing the system to boot at 3600MHz with CAS 15. I updated the setting in Ryzen Master and adjusted the BIOS CAS value, and everything now works properly. It’s important to note that I altered the SOC voltage to 1.25V, but I couldn’t locate instructions for modifying vddp or vddg, so I left those unchanged. (Auto)
