This is my first time ever messing with RAM overclocking, and I really want to learn more about it. Since I’m a total beginner, i used ai a bit to be sure that i wont damage ram.
A few days ago, I got a 4x8GB 3600MHz CL16-16-16-36 kit (G.SKILL TridentZ rgb, and they all are samsung b-die) and immediately started overclocking it. At first, I just managed to hit 3600MHz CL15-15-15-35-50. After that, I successfully pushed it to 3800MHz CL16-16-16-30-46 at 1.520V. I was already pretty happy with it, but at that point, I hadn't even touched the secondary subtimings yet. By default, my motherboard auto-trains them as follows: tRRD_S: 4, tRRD_L: 9. tFAW: 44, tWTR_S: 3, tWTR_L: 16
An important note regarding the frequency: pushing anything above 3800MHz results in an immediate BSOD (Blue Screen), no matter how much voltage I throw at the memory controller. It seems my CPU's IMC simply hit its physical wall, so my main goal now is to take absolutely every bit of performance out of 3800MHz.
As for my setup, I have a pretty decent case (Chieftec Apex Lumo Air) with three 140mm intake fans at the front and one 140mm exhaust fan at the back, all running at around 1000 RPM during my tests. I also have two 120mm top exhaust fans (mounted closer to the back) running at 900rpm. For the CPU cooler, I am using the Thermalright Phantom Spirit 120 SE. When its fans run at 1100–1300rpm, it doesn't really affect RAM temperatures, but if I drop them below 1000rpm, the RAM instantly gets 2–4°C hotter. I guess that's fine, especially since the front fan of the CPU cooler sits directly over the ram slots, almost touching the sticks.
Anyway, as you can see from the screenshots, I managed to get some great numbers in AIDA64 and almost passed a full cycle of the TM5 Anta777 extreme profile. However, right at the very end during Test 15, a few errors popped up exactly when the hottest stick breached 54.8°C. Gemini tells me that stabilizing 4 sticks with these tight parameters is already a huge achievement, but I really want to get the opinion of real professionals here.
Could you guys suggest any tweaks to lower the temperatures without losing my current performance, or maybe this is still not the maximum limit of these sticks?
