yeah I know what HCI is, but the screenshot provided by the website that benched the gskill kit didnt use HCI.

@humbug you forgot to mention that You are talking about bolts before or after vdrop. If after vdrop.ots useless as every motherboards llc behaves in different way if set on manual. So on 1 motherboard 1.35 after v drop will be 1.3 on other it will be 1.34 and on other 1.270.

Thats why i say people need to start talking about vilts under load after vdrop from VRM. Like for me on aito to have 1.35 after vdrop it takes 1.425 vcore great voltage for idle init??

Thats how I always report my voltage as well, e.g. in my 8600k threads the voltage I report is "after" vdroop has taken affect, "not" what is configured in the bios.

Same with my 2600X also.

OK so I am trying yet again to clock my memory.

I've watched the video so I know of at least thing I've done wrong. I've exported my settings from Typhoon burner and imported them in to dram calculator.

Set my settings including the speed my ram is rated I can press safe and fast to get timings etc...

But what's the process now of getting this to run at 3733MHz. I know it can do it as I'm currently in typing this with my ram at 3733MHz (16 16 16 16 36 at 1.4v) But these are just timings I typed in.

Do I put these settings in to the BIOS and then start upping the frequency until I get instability and then start upping the dram voltage?

What's interesting under advanced it says overclocking potential:

3674MHz CL14. Memory chip quality 93%.

Should I aim for 3600MHz C14?

have you changed the timings to ns?

Zeed had had to take a little holiday from the forum until tuesday from breaking the swear filter, he offers his apologies

Lolz

I thought it was a bit quiet around here.

I've given up in the end.

I've got timings that do work.

16 16 16 16 36 - 3733MHz - 1.4v

This gets me in to windows and gaming

Still to prove 24/7 stability tho.

Watch away! I'm quite interested at when I explode in a shower of silicon.
It works very well so far though, seeing massive improvements in games, but I wouldn't recommended using this board for a 3900x.anything lower will be absolutely totally great though.
I need to get off this motherboard before my tweaking fetish kicks in and I start pushing this too far lol

It’s actually a 3900X I’m looking at so I hope that our mobo is up to it.

Got a large case and good cooling which may help but I’d heard that the VRM’s aren’t up to scratch. Would have picked something different had I known when I bought it for a 2700X build TBH.

Same, I was proud of myself that I got a x470 back then, only to discover I could have paid less and got a much better x370.... Sad but it haapens sometimes I guess

Sounds like it's fair to say there are still teething issues with these Ryzen 3 CPUs... from skim reading the various threads here.

Think I might wait until next year when there are proper working firmwares available, etc.

Weird that the launch seems kind of half-baked/rushed.

The motherboard vendors seem almost entirely unprepared for the launch. It's very odd.

The new chipset driver helps: as per testings https://www.techpowerup.com/review/new-amd-chipset-driver-performance-test-ryzen-9-3900x/2.html

Not read it, but is that helping single core?

opethdisciple · 3 Aug 2019 at 00:26

Dunno if already posted but seems very informative:

opethdisciple · 3 Aug 2019 at 00:30

I thought after 3733MHz the IF goes from 1:1 to a 1:2 divider?

In my BIOS I see FCLK, but no UCLK?

When I set FLCK to 1900 I get audio corruption in windows and eventually it reset the PC. 1800 seems fine tho.

Does my memory frequency need to match the FCLK tho? I kind of thought maybe you need to set the FCLK to half the memory frequency but not sure?

I think it's simple the heat is so concentrated were seeing the thermal interface be a greater issue than ever before.

You can bolt some serious watercooling on but getting the heat from the tiny chiplet quickly enough is the issue. I haven't seen any direct die cooling results yet but I suspect we'd see big improvements.

I think you are right. Debaur will likely do this.

Illuminist · 3 Aug 2019 at 13:21

So can I get this straight, the best ratio of 1:1 is ram at 3600 or 3773? With the If at 1800? I finally caved and went for a x570 board just to make sure.
Also does anyone here have 3200 cl14 8Pack team ram and what do you squeeze out of it?

michty_me · 3 Aug 2019 at 13:31

Ouch, Just seen some competitors now have the 3900X priced at £589.
I'm severely tempted to pull the trigger on a 3800X for £385

The videos I posted above answers this question.

You can think of your FLCK as half your memory frequency.

The way he says going about doing this is push your FLCK first, find what it maxes out at and then run your ram at twice that speed.

So for example it seems for me my FLCK tops out at 1800 so I put my ram at 3600MHz. The only thing left to now get performance out of it is to tweak timings.

Start by putting your FLCK to 1900 and ram something low and see what happens. I got audio corruption in Windows. The highest frequency where this stops was 1800 FCLK.

Once you know your max FLCK your know your max memory frequency.

---

Side note. The max 1:1 ratio is 3800MHz hence the max FLCK of 1900

---

Of course I am assuming that the max FLCK you find is also stable. It might be wise to leave your ram on default speeds, FCLK as max as it seems good and stress test it a bit.

Oh so I can unlink them, I tried this on ryzen master and it wouldn't let me, so I can set the if in the bios to 1800 or 1900 and the ram to whatever I want?
