*** AMD "Zen 4" thread (inc AM5/APU discussion) ***
- Thread starter 4K8KW10
- Start date
Motherboard arrived to add to my corner of boxes and bits!
Just waiting on new SSD (Samsung 990 Pro 2TB) and EK blocks now (Velocity2 AM5 and Vector2 FE), but if they don't arrive soon I'll get a cheap AM5 air cooler and set everything up to test.
Plus I have to strip down my case and clean everything anyway, flush the rads, grease the fan bearings, new o-rings for all my fittings and pumps etc.
Memory is the G.Skill 32GB 6000mhz CL30 EXPO kit (F5-6000J3038F16GX2-TZ5N) and CPU the 7700X to get the platform up and running while we wait for the X3D.
Think I'll update my old project thread at some point when I get going with things, been looking back at it and reminding myself what I actually did has been really useful.
[Project Nebula] - CaseLabs TH10A
Going with EK ZMT and will change to the black AXi PSU cables so probably call it Black hole this time

^^^ £1000 MOBO!! Bejeeesus! It can build itself for that much.
Dang right - for those who dare! (not to tell the mrs)

Haha, it was only £783 + vat
Only board that had everything I wanted and if like my current one I keep it for 5+ years then no worries.
Got to RMA my aio as it has a really high pitched noise. Feel like this build was doomed from the start lol. Set CPU to 105 eco mode, but until I play some games I can't really tell how it is. I noticed the Lian Li fan control software shows my CPU at a much higher temp than the Asus software too, about 10-12degrees more.
Still no GPU, nothing really attractive out there

Erm.....
Not quite sure tbh looking at that.
Sapphire rapids is going to have it's work cut out against that. No wonder they don't care on Ryzen selling well or not! They'll just allocate the dies to the Eypc chips instead for a massive amount more ££££

And the 9654 is only a 96 core.
Wait for The EPYC 9754

How are Intel still selling these things? This is brutal.
Easy, I'm a business that needs to upgrade, all I know is I had Intel before and it worked great so I go Intel again. You get people who when they find a car they like he they'll just keep buying that brand of car again for the rest of their life - people who only make big ticket purchases once in a blue moon are less likely to be risk takers and they tend to stick with what worked in the past. Do you know how many banks are still running some software from the 80s? A lot

I found out that my Ryzen 7700X CPU can handle a curve editor magnitude of -30 on all cores, so actually quite a good chip
Tested for a few hours with both AVX disabled and AVX512 enabled, at the default JEDEC DDR5 profile setting (4800 MT/s).
I discovered that the default XMP setting for 6000 MT/s was causing rounding errors in Prime95 (and occasional crashes too), which for a week or so, I thought was caused by the CPU, as these errors only occured when curve editor was enabled (also, Memtest86+ showed no memory errors when I tested this XMP profile)...
My motherboard does support the DDR5 Renegade Fury modules I picked, but doesn't have official support for the 6000 MT/s XMP profile (annoyingly, other Hynix M die Kingston modules are fully supported - Could be a sign that it doesn't like the tighter timings?).
I recommend running the memory / latency benchmark in Aida64, I found that increasing many of the motherboard voltage settings to 1.25v (I strongly recommend leaving VDDP at default to avoid booting issues!) and the DDR5 voltage to 1.4v allowed me to set the curve editor to -30 without crashes / instability.

I have the same CPU and RAM, but my motherboard (B650 Tomahawk) does support the 6000 MT/s profile according to the QVL; however, it's not stable in windows at those speeds. I just assumed it was related to the CPU memory controller. I set mine to run at 5600 MT/s with everything else the same from the 6000 MT/s profile, and it passes all stability tests I've thrown at it so far.I found out that my Ryzen 7700X CPU can handle a curve editor magnitude of -30 on all cores, so actually quite a good chip

Interestingly, my chip is also stable at -30 PBO curve offset - not like me to get decent silicon.
So, no rounding errors in Prime95 (AVX off) after 1 hour with the 6000 MT/s XMP profile set, with the DDR5 voltages set to 1.45v (1.40v wasn't enough juice).
I had to enable the 'High voltages' option under the DDR5 BIOS settings, to increase the voltages this high.
Interestingly, my B650 motherboard does not allow one of the memory voltage settings to be set over 1.45v, so I'm basically maxing it out.
Hopefully this is going to be enough for stability?
The DDR5 temps (SPD Hub temperature) of both modules are reported to be upto 64 degrees C. What's the maximum safe temp for DDR5 modules?
I'm having a slight sense of de ja vu, because my DDR4 RAM in my last system was having crashes with the XMP setting for 4000 MT/s enabled too (until I turned up the DDR voltage).

Yeah it's months away, why wouldn't they be and way too early for any sort of Zen4 3D news/leaks. To expect anything before the GPUs drop is probably going to be disappointing tbh. And showing them at CES means and end of Match release likely.
The spec sheet for the RAM I'm using suggests a max operating temp of ~85 Celsius according to the spec sheet:
So, hopefully no problem to keep it running like this.

So running that XMP #1 profile needs 1.45v up from 1.35v to get it stable?
It does on my board by the looks of things. The modules are supported to run at JEDEC spec (and 'OC' as well) by the motherboard, but XMP isn't ticked on the QVL list:

This motherboard has a higher grade PCB, does support the same RAM, but doesn't support XMP @6000 MT/s:
https://www.asrock.com/mb/AMD/B650E PG Riptide WiFi/index.asp#Memory
Which makes me think this is probably something that can be improved with a BIOS firmware update.

Interesting! Wonder if there is an equivalent kit that is on the list with the same timings and memory chips at 1.35v?
Would be curious to try another kit with the same setup to see if it works or needs more voltage too.
