So recently, I was wondering whether there were any bits of juice left to squeeze out of my PC. I've tweaked my memory timings, FCLK/UCLK/MCLK, and played around with AMD PBO.
Currently, my settings are on 2200 FLCK, tweaked out Micron D-Die RAM with the tightest timing I can achieve on 6000MT/s, and squeezed out PBO with +200 boost clock and negative offset per core (around -30 to 40) on Curver Optimizer. I achieved stable OCCT, Linpack, and Testmem5 without any WHEA, crash, BSOD, or other things in a lengthy stress test.
In safe mode, I achieved around 59 ns latency, and in normal boot, with a score around 3726 on Cinebench R23.
Recently, I read an old article from here, saying that adding 0.1 to your BCLK can result in a more fluid mouse and less stutter in your games. So, I toyed around with BLCK, starting from adding 0.01 (which ASUS board rounds up to 0.0625), 0.125, and lastly 0.250, resulting in 100.25 BCLK.
I tried 100.5, but my system failed to start, and I had to CMOS reset my PC since it wouldn't go into BIOS or the Failed to POST Screen. I hypothesize that since I'm already running FCLK on my CPU's MCU limit, my max is on +0.250 BLCK.
I can tell that my system runs smoother, and runs AIDA64 latency, resulting in around 58ns, a 1ns reduction in latency. I also see an increase in Cinebench score to 3729, which is marginal in terms of increase.
But the point is that adding a 0.1 or 0.25 creates a smoother experience that just tickles my brain. I can tell when playing competitive FPS games like Valorant that the average frame time render is a bit lower.
I would like to hear feedback from anyone who has tried this tweak. Is there any inherent risk to this tweak? I read that it's usually safe since the Motherboard's "CPU Spread Spectrum" also adjusts the BCLK, ranging from 99 to 101.
Btw, I haven't run any extensive stability tests yet on this current tweak, just a quick Linpack test to see whether any error corrections are happening in the system. Will let you know the result later.
