Question Zen 4 builders thread

[Markfw]

I know its early, but as someone pointed out, I better get my ram now before the scalpers are all over it.

To go with a 7950x, what do you think of this ram:

Its not obvious until you read the manual, but look at the HSF provided for the Gen 5 NVME !

Are we coming back around to using U.2 connectors (or something like that) and putting the drives in a 3.5" bay compatible heatsink?

No, that sits directly over the NVME driveI will take a pic once installed.

Edit: Okay, here is motherboard with CPU, NVME drive and memory installed:




This is the other motherboard, Identical except this is regular, not the white crap. It would not let me buy 2 of the regular, so I wasted $30 for the carrara.

We really should. Pushing desktop to M.2 form factor was a mistake.

 

[Markfw]

Just an observation. When I started this thread, is was almost 2 months ago, and I did not have a release date yet, but already bought some parts.

2 months later, I will have my first system running, maybe before. If I get lucky, one might be up today, and the other tomorrow, otherwise probably Sunday before I finish both.

MicroCenter offers free 32GB DDR5 memory kit with AMD Ryzen 7/9 7000 CPUs - VideoCardz.com

Free 32GB DDR5 memory kit with the newest Ryzen 7 and Ryzen 9 series US retailer is giving away $190 worth of DDR5 memory with select Ryzen 7000 CPUs. MicroCenter is now making a compelling offer on Ryzen 7000 CPUs, but only in the United States and only with in-store pickup. The company is...

For those who staying nearby MC, go grab 7700X with 32GB for under $400 is insane value

Well that was the easiest upgrade ever. Took maybe an hour to get the old stuff out, new stuff neatly in, and it started right up. Windows spent five extra seconds detecting the new hardware and is now good as new. EXPO timings for the free Microcenter RAM in the screenshot below -- might help tweaking subtimings for people with XMP kits. This RAM isn't the fastest but certainly isn't bad .. it will definitely do until some good fast 64GB kits hit the market, which is what I really wanted.

 

[Markfw]

OK, build one complete, hardware wise. I set it to XMP1 32-38-38-96 6000, and its booted the windows install USB @!!

Stay tuned.

Would it not be a wise idea to wait until after Windows is installed before you start adjusting clock speeds? I'd want the PC as stable as possible while installing Windows.

Tiny Tom says RyzenMaster ECO mode is nerfed. https://overclock3d.net/reviews/cpu...yzen_9_7900x_7950x_cpus_until_you_read_this/1

Stick to using UEFI. He provides the values here if anyone needs them. https://overclock3d.net/reviews/cpu_mainboard/amd_eco_mode_guide_for_am5/1

Well, I just used XMP one. And all the settings were correct. Doing updates now. It will run linux after I have done stuff in windows. Not a great pic, but here it is completed. I will run some benchmarks and stuff after all the updates are done.

I'm sure it'll deliver excellent results in your distributed computing farm. Have fun with it!

Well, windows will not do the updates. AT DEFAULT BIOS SETINGS. linux is up and running. More updates tomorrow, I am done for today

Maybe then the u.2 port on my x370 would be actually useful.

 

[Hail The Brain Slug]

I got my system up and testable and noticed in the UEFI once I enable the EXPO profile, there is a "low latency mode" and a "high bandwidth mode" I can toggle on, which seem to make a considerable difference to the readings AIDA64 takes. It seems to add around 10% bandwidth and lowers latency by a few ns.

No idea what they are doing, I'm guessing some secret sauce timing adjustments. Memtesting overnight to see if those settings are stable.

I will post the 6000CL30 expo profile details tomorrow.

Does your UEFI expose all the subtimings?

It still is. Get a U.2 Optane drive for fun!

I have an itch to build a 7900x rig lol. Wondering if i should sell my 12700k stuff to a family member and grab a
7900x
Asus strix E
G skill Expo memory.
Would you all say it would be worth it from a performance perspective?(gaming and light video encoding)
How does Windows 11 feel using Am5? Does it feel a little more responsive?

I would hope windows is responsive on a 12700k.

 

[CakeMonster]

I can't imagine that would be worth it, if you need an excuse that would at least have to be a 7950X. I certainly understand the itch though.

 

[Det0x]

System up and running

 

[CakeMonster]

Nice! Would love a report on how EXPO is working out.

No chance of slowdown for any thread on 7900X since all cores are identical in performance.

AMD Ryzen 9 7900X Review - Creator Might, Priced Right - Power Consumption & Efficiency | TechPowerUp

In the average of both application and gaming tests, 7900X is beating 12900K from a power consumption perspective. You will get better than 12900K performance at lower power usage. 15% better average performance than your 12700K in applications and 2.8% lower gaming performance. Faster in H.265/264 encoding but loses to 12700K in AV1 encoding.

Think of the savings from lower electric bills over the lifespan of the 7900X system.

Video encoding may benefit from AVX-512 which is not supported on Intel Core 12th/13th gen anymore.

If gaming performance is more important, wait for Zen 4 V-cache SKU.

 

[Det0x]

Hmm i seems to be having problems booting above 6200MT/s with my 7950x, but it does 2200mhz FCLK like nothing..
Lucky sample or is this normal ? I thought most was limited to 2133/2166mhz max ?

BTW do anyone have ryzen master screenshot from anyone running 6400MT/s on dual CCD Zen4 ? I want look at their settings.. Do they up the IOD and CCD voltage ? I'm still running stock 850mv on both. :unsure:

I'm getting 59.3ns in AIda64 @ 6200MT/s memoryspeed and 2200mhz FCLK.
CPU is still running stock. (no PBO CO atm)

Gonna try 2233mhz FCLK next

 

[Hail The Brain Slug]

Results from just flipping EXPO 6000CL30 profile on, enabling low latency mode, enabling high bandwidth mode. I checked the numbers against the latest Aida and they match so the old version is accurate.
