AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

Gskill selling 3800 zen2 kit. They could have shown 1000% HCI pass as an well known memory vendor i seen fails at 200%+ :D

https://www.overclock3d.net/news/me...vhE1Cpp33jVK4lgWFF8tZmv4ke5tOkwWaLO3JhOtAi-As

I should be able to drop main clock to cl14 and fixt timings up a bit not gone to CL14 theritory yet to test. As on OCN we noticed performance gains from cl16 to cl14 are very low on them 3733/3800 clocks. But ill drop em after i get home to show ya what sorts of gains there are.

@8 Pack any update on Your's Zen2 dedicated kits ??

never heard of that ram test tool they used.

When will they release 3800CL14 32gig kit tho?
 
The issue I have with these stability tests (HCI for example) is they are not representative of real world work loads.

Being X % stable in HCI means you are just stable in that one particular workload.

You try something else and it falls over. As I've seen with being 400% stable in HCI and yet still unstable in games. Waste of 3hrs to test it to be honest.
 
There is very few reports of people doing long hours of HCI passing, and then been unstable in their normal workloads. The big reason HCI is recommended over the lies of memtest86 e.g. is it represents real workloads better. But of course nothing is a 100% guarantee. Some people can frequently clear 4 hours in HCI but then fail at 10+ hours.

There is also alternate tools to try (effectively second opinion tools).

For windows there is also karhu ram tester, this one allows you to tweak the test such as reducing or increasing load on the internal cpu cache.

Also when you say you unstable in games, what is happening, and are you confident in your diagnosis that it is memory timing related?

It's the only variable I'm changing. I don't overclock the CPU or GPU. Only the ram. It was fine for about 5hrs in 3 games, then I got a crash in new Wolfenstein. Tested the memory using HCI and it passed 400%.

Last night tho playing AC Odyssey game freezes with just the audio playing. I'm fairly confident it's the ram. Like I said only variable I'm playing with.

Still recommended to get the b450 carbon ac over the tomahawk (MAX?) even with the more basic bios? Is it just more basic looking or does it lack any features? Already got 3700x on order.

It's basically the same just doesn't look as pretty. They're adding features with every release (which is fairly often at the moment) such as OC profiles. Not sure about raid but do check that if it's likely to affect you. IMO you get better value for money with the Pro Carbon.
 
Anyone on the non-master gigabyte bios (F4h for example, the ultra/pro boards bios) have experience with 1003ABB.

I'm stable but untuned on a release bios atm, waiting for a good bios to go to and sort out memory timings around the same point.

Wait what You not heard about BEST and known for years HCI Memtest HOW ??

@opethdisciple but HGCI test's Memorty stability NOT IMC or IF stability. Ramm all fine Its IMC and voltages ****** UP not memory !!! Thats why You dont do AUTO !!!

@Smak Aida is indeed quite nice for stability testing so is Realbench. I do love my IBT also :D

I'm a ram noob. This is why for me I want just plug and play DOCP. It sounds like @Smak is running auto tho. I hear you tho. This is what I mean. HCI tests ram. Not real world stability as although your ram might be fine it's other parts of the system that haven't been tested that fall over.

The DRAM calculator tho even for 3600MHz recommended me 1.4v despite my 1.35v being 400% stable in HCI.

My RAM's XMP is 3866-C18 so I've manually set to 3800-C16, CPU is auto though.

DOES NOT MATTER ryzen likes 1.4 on ddr's due to how voltage leak works.
You put all **** from calculator then test if its working or not.

Interesting, the biggest loss is 2%, the biggest gain is 8%, most around a 3% to 4% gain.

Ill have to check the stability of the official ones. Maybe they can pass stress yest of ucruncher and ibt. We are still sitting on 1.0.0.2 microcode that could be reason they dont play allong as they are more of an 1.0.0.3ab+ ones

If all goes good 1.0.0.3add should be out tomorrow for testing on asus motherboards.

Okay, my 3900x arrived and is installed, on the latest gigabyte bios 1.0.0.3ab? F41
How do I get this puppy flying?
I can see a bunch of new options in the bios about the IF, and manual overclocking options..
It seems to be auto clocking to 4.3ghz at the moment, all I touched was xmp on for the ram.
What do I do first for either the peak auto settings or a good manual overclock?

I tested Auto Overclock on my 3600, +100Mhz, it worked, under high stress load the CPU stuck to 4.1Ghz, vs 4Ghz stock, stuck hard at 4.2Ghz all core in games from varying from 4.05 to 4.150Ghz.

But over 1.4v which i'm not comfortable with.

And i have learned something, my Motherboard has hardlocked my CPU to a maximum of 4.2Ghz, not matter what i do it will not go over that.

You should set volts that you are comfortable with, 1.325 to 1.35v is safe 24/7 and see what you can get out of it like that.

However, the CPU its self will clock its self higher just boosting, it knows when it can use more volts, like up to 1.47v without damaging the CPU.

I would just leave it to do its thing unless you can get about 4.4Ghz stable on a maximum of 1.35v.

Just going to have a think about it, but without spending a lot more it seems like the best choice i guess.
