not sure bro but i will give it a run, basically anything above 3733 is thrash, even @ 3733 i think cl16 best is sub 70ns with trfc tightened a lil @ 389.

as for monitoring i will try hwinfo64, giga own monitoring sw is so tiny that it's hard to show readings properly on screenshot...

very nice clock there bro... i wish i have a chip can do 3800 @ 1:1...

nice primary timings but something is still way wrong there.
both bandwidth and especially timings are way sub par.
Your results should be more like high 56k / 30k / 56k and your latency should be >10ms lower than what you have right there.

wanna take a screenshot of ryzen master listed timings & config?

Actually true also, 3800c14 should be getting sub-70ns latency..

3600C14 also can get sub 70ns as well

My stock non-tweaked 3600c18 is getting 72.2ns

Very plain 18-22-22-42 Micron B-die


Attached thumbnail(s)

4x8GB 3200mhz C14 tweaked to 3600mhz C14, based on latest ABBA bios, slightly improved on the overall memory performance

with HCI still runnin, & not on 1:1, it is possible guys...

sub 65

edit, for reference
3600 instead of 3600x
same board
2x 8gb sr b-dies, likewise
same primary timings

this is what you should be looking at, ideally

very nice bw, latency & clock there bro... how u guys can have such high clock is beyond me... jelly...

tbh, this is not my setup, I just used it as example for @owikh84 as primaries, board and basically cpu were same.

so looking forward for him to share his settings should he wish to figure what the limiting factors both in bandwidth and especially latency are.

typo on trc in bios resulting it @ 135, apart from sucky bw d latency is actually not bad...

'quick' set up for friend, 4x8gb sr on a b450 aorus m paired with a 3700x.

have to admit gigabyte did a good job with stability and functionality, they're making progress.

If I just want to overclock ram to 3200 and run cpu in stock, does vrm configuration really matter? Im building one with crap tier Asus B450 board.

answer must be no... VRM just for powerful cpu that want more power......

U can do that even with 1st gen ryzen. I would say its very2 doable on all am4 boards bar 320 chipset based boards, provided d chipset itself (used on d ram) is not too lousy. Mfr, afr, cfr, cjr, samsung c, b, micron b, e should not even sweat to do a 3200. Boards with Lower tier vrm shouls be just fine for 6 cores (auto) without being whipped with high clock n volts.

Some suicide run when i still had my buddy's 2700x...

Alright noted. Thanks.

lol that one sick oc. at that point I will worry more about power consumption than anything else.
I made this rig for a rather tech illiterate friend who "just want to play dota", so im going to stick with conservative tuning, lest the rig become unstable and I ended up being unpaid tech support.


Im doing this on R5 2600, with just single module, so yeah 3200mhz should be almost work out of box.
But this board (Prime B450m-K) is very sad one. It doesn't even have vrm heatsink so im not going to put too much trust on this board even for ram oc.

just suicide kinda bench, meaningless really, like cpu-z validation.

vrm (especially cpu) has nothing to do with ram mileage i supposed. imo, how well asus implement the agesa will determine how far is d mileage on ram. i could be wrong thou.

Bingo, not being able to do FCLK 1900 at DDR4-3800 with my 3600X chip has seriously killed my latency and bandwidths. There's a 10ns penalty for 3800/FCLK 1866. At 3733/1866 (1:1) I could get sub 70ns and better bw.

I also came across an article from an ex-ROG staff doing comparisons of memory performance on 3600X/1xCCD vs 3900X/2xCCD: https://elmorlabs.com/index.php/2019-07-10/...0-investigated/

We can see significant differences in terms of mem bandwidths with 3900X over 3600X.
It is also suspected that dual-rank and 4x8GB DIMMs are capable of delivering higher bw.

you can't boot or can't get stable with 1900 if? tried adjusting vddg/soc?
u'd kind of expect a better i/o die in an 3600x

Cant post at all, stuck at debug code 07 displayed on mobo.
I've tried playing around with VDDG up to 1.1v, SOC up to 1.15v but none of them seems to be helpful.
I also tried BCLK 102 with FCLK 1866, getting the same error code.

My BIOS settings as follow:
