Overclocking Memory.

[GinGo]

Can anyone give me any advice on overclocking memory? I've never done it before and from what i've heard i can't exactly do damage, if it's wrong it just won't boot, but can anyone give me some pointers, the does and don't.

If it helps, i have the Asus ROG Strix B450-F Gaming Motherboard and Team Group 8Pack Ripped Edition 16GB DDR4 3600Mhz Memory.

Thanks!

From my limited experience I would firstly try and see how fast the memory/infinity fabric can go. I started going from the 'default' (think it was either 1200 or 1600MHz) upwards by 100MHz until I reached 1800MHz (3600MHz effective) for RAM and Infinity Fabric (FCLK), to maintain 1:1 ratio (if you break the 1:1, you get penalised in latency). In between all these I would run Cinebench and 3D Mark CPU to ensure some stability and check if I'm progressing performance wise. At some 'checkpoints' where I thought the likelihood of stability might be decreased I ran some blender benchmarks for about 30 minutes, to stress the CPU (I have the 8Pack 3600MHz C16 32GB RAM, so was rather confident of its ability to overclock; not so much for the CPU, hence why I focused on CPU benchmarks).

I then started going up by 33MHz, 1833-1866-1900MHz, again running some benchmarks in between. Voltage wise, I went for 1.45V, as that's the rated memory voltage. At 1933MHz the PC wouldn't boot, so reverted back to 1900MHz.

I then started playing with timings, using what others have suggested (1usmus DRAM calculator). In my case, I haven't managed to alter the timings much more without experiencing non-boot. I am running at 1900MHz/3800MHz with 16-16-16-38, which isn't too bad. My 1usmus score is 235, which is above the 200 figure I've seen people striving for, so perhaps I should go back and try tighter timings with lower speed and see if that affects things.

That's not strictly true, you can corrupt files if your system isn't stable. I wouldn't overclock memory if file integrity is really important to you.

I'll try and go in small increments to ensure accuracy and stability then i assume. as i forgot to mention but the memory i have is CL14

Would going in smaller increments be "safer" for file corruption? Also, would it just be windows/C drive be the one that just suffers from this if it were to happen? Or would it be any drive i have connected?

If you're writing data from memory to disk then they're all vulnerable, but the system drive is more vulnerable than storage drives because it's always reading and writing. There's not much risk to an untouched archive drive, for example.

Smaller increments would lessen the likelihood of corruption because the memory will be more stable at any given point, but I'd really not want to be doing this unless it's only a gaming or benching machine.

Yeah, i only use my PC for gaming really, nothing important is every on my Computer, Windows, Games and maybe just some pictures and random files which i already have backed up anyway.
