Which overclock is better for gaming?

breathe3asy · 28 Apr 2022 at 12:45

3800mhz 16-16-16-32
or
3600mhz 14-15-14-30

I'm on the X370 chipset using a 3900x with PBO enabled and everything else default.
Memory is samsung b die.

Either overclock seems to make no difference in games vs stock XMP 3200mhz 14-14-14-34 so I'm wondering if its even worth it, or if frequency vs timings makes a difference.

No I'm leaving all CPU values default apart from enabling PBO as said. Does the higher RAM frequency not make the IF run faster as a result?

Its on Auto and just having looked at hwinfo64 the IF is at 1800mhz which is half the current speed I am running.

Any idea on differences between the two frequencies/timings in OP?

Thanks guys. Out of the options below which would you pick:

1. Set to XMP (3200mhz 14-14-14-34), leave default and live a happy life
2. Set to XMP, tighten timings to 14-13-13-26 and leave alone
3. Set to 3600mhz 14-15-14-30 for seemingly no difference and more voltage
4. Set to 3800mhz 16-16-16-32 for seemingly no difference and more voltage

Be interesting to see results if I wasn't GPU bound, just wondered what settings were best on paper is all

I'm confused as to why you have both come out with 14-15-15 after I had said 14-15-14? I thought lower was better?

My BIOS automatically sets FCLK to half of speed of RAM, even at 3800 RAM speed the FLCK will be 1900

breathe3asy · 30 Apr 2022 at 12:45

Yeah cpuz confirms but I can only get 16-16-16-32 at 3800

breathe3asy · 30 Apr 2022 at 12:54

Oh sorry my mistake, I've just set my RAM to 3800 and the IF is showing 1800

Ok cool, just running some tests in Aida64 is it the latency benchmark I should be most interested in?

breathe3asy · 30 Apr 2022 at 13:04

I don't know how to improve my 1% lows but yea I think I am heavily GPU bound but good to know my RAM is in the best position for when I do slot a new card in

Finally got round to tuning this and settled on 3800mhz, for reference figures seemed to be slower when running 3600mhz with tighter timings, but could I get a sense check on the below please? Do those latency values look OK? Trying to tune for gaming.
