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:

AMD AM5 AGESA have some bugs..


But we can exploit this..

6200MT/s and 2133mhz FCK --> real memory speed is 6400MT/S

(can avoid the latency jump at default 6400MT/s memory strap)

Ok I have a memory issue. I had some Trident DDR5-6600 memory That I couldn't get to post past 6200. I thought it was the ram, so I returned it. I look on the stores website, and see that they now have Trident Z5 RGB DDR5-6800 for less than the Trident-6600, so I got it.
However, it also won't go past 6200. What am I missing? I know that AMD said 6000 was the sweet spot, but I wasn't expecting this.

From your motherboard manual.

4 x DIMM, Max. 128GB, DDR5
6400+(OC) / 6200(OC) / 6000(OC) / 5800(OC) / 5600 / 5400 / 5200 / 5000 / 4800 ECC and Non-ECC, Un-buffered Memory*

Dual Channel Memory Architecture Supports AMD Extended Profiles for Overclocking (EXPO™) OptiMem II * Supported memory types, data rate(Speed), and number of DRAM module vary depending on the CPU and memory configuration, for more information refer to www.asus.com for memory support list. * Non-ECC, un-buffered DDR5 memory supports On-Die ECC function.

So while it may support 6400+ it will be module specific. Perhaps your voltage is too low for that particular module. Here is the QVL list: https://rog.asus.com/motherboards/r...hair-x670e-extreme-model/helpdesk_qvl_memory/

Probably voltage tuning.. But if your not prepared to spend countless hours in bios tinkering i would simply recommend to get a 6000MT/s EXPO set and be done with it

But if your deadset on doing manual tweaking, you can use these as ballpart figures: (every cpu (IO-die) is different -> what works on mine don't necessary work on yours)

Active cooling on memory is recommended with this vdimm

Seem to be correct:

AMD Ryzen 7000 series get up to 27% lower price in China for a limited time - VideoCardz.com

AMD Ryzen 7000 series get significant price cuts in China AMD Zen4 desktop is up to 27% cheaper for a limited time. Just a few days ago, AMD implemented new pricing for Ryzen 5000 (Zen3) desktop CPU series through their official US store. However, it seems AMD is now applying new pricing...

videocardz.com

The new platform in china is about 10% more expensive than US/EU, and maybe due to tax/transport/currency issue. And any price being discounted heavily in Nov.11 is china exclusive, slash down platform cost and make it looks like to be comparable to US/EU. I think it's just a strategy of sales by AMD's chinese agent. It's hard to see price slash like this in other countries.

My memory isn't on the QVL, and my Microcenter didn't have any EXPO ram. I guess I need to look for some from anyone but Newegg.

I have 26 days before I return it, so I'll play with it. This looks awesome, thanks!!!

7000 series is getting a small discount over here in Aus.Perhaps there is the potential for sales during back Friday after all. I know I will hate myself if I get a non 3d CPU though

I have 2 kits of this, one in each of my 2 7950x. I just set it, and forget it, works great ! DDR5 6000 CL 30-38-38-96

A quick question. What is the memory frequency required to run 1:1 with Infinity Fabric @2000MHz? DDR5-4000?

Yes indeed, watching the market like a hawke atm. After studying AM5 in more detail thanks to more time, I'm inclined to go down that route for next upgrade due to the iGPU being mighty compatible with my RX 6800 XT & the idea of not having e-cores to get in the way of software compatibility is a thing too.

Found another extremely annoying bug with this stupid Asrock board. I have one 4TB SATA storage SSD and I plugged it into the top port when I put the motherboard in. I've been chasing driver_power_state_failure blue screens on and off, and lately it's been consistent after about an hour of leaving the PC on with corecycler running (but totally fine just idle). That obviously made me think hardware failure since the CPU had to be loaded with corecycler specifically.

I finally downloaded the windows debugger tools to look more closely at the minidumps and turns out every single one is caused by storahci and specifically my 4TB SSD not responding to power management requests. I looked into the motherboard more and the SATA port block diagram is a mess -- only the bottom four ports are actually AMD chipset ports, the other four are some Asmedia garbage with PCI-e switchers or some trash like that. Switched the SSD to an AMD-provided port and blue screens are gone

I don't really care about those SATA ports but it would be nice if they worked at minimum.

I have this Kingston kit which is *not* on your MB QVL list. But it has EXPO and is QVL on Asrock I am using. Works @6000 (as it should being QVL)

Thanks, but I have new ram being delivered today by way of Amazon.

I took advantage of the Microcenter deal recently to upgrade from my aging i7 5820k. -$50 on Mobo ($150) and free 32 GB DDR5 6000 CL36. Man was my old CPU bottlenecking me bad. My frames are so much higher now. Also I'm undervolting and power limitting it without losing performance.

Free RAM made this deal too good even though I know Intel is ahead in gaming right now. Also Zen 5 3D Cache chips are coming in 2025 so that should be a good upgrade as I'll get a faster architecture and the 3D Cache benefits.

It's not clear fron your post, what SKU did you get?

Also, if you weren't considering getting the i9K, then there isn't much to "Intel is ahead in gaming right now", both i5K and i7K are slower than Ryzen 7000 in gaming.
Either way, it's splitting hairs here, I just thought unless we're talking about SKU v SKU, blanket statements are often untrue and lead to public misconceptions.

 

[AdamK47]

Made some changes.

Bought some Hynix A-die memory. You know... in case I decide to go back to Intel at some point.

Bought more fans to quiet down my system. The Corsair ML140 fans that came with my H170i Elite cooler were a bit too buzzy. Moved the SP140 fans that came from the front of my 7000X case to the bottom of the 420mm radiator. Put four QL120 fans in the front of the case (took three I had from previous case and bought 1 more). Bought three LL140 fans to put at the top of the 420mm radiator so that I now have a push/pull setup. The SP140 rear case fan remains unchanged. I keep the SP140 fans at 50% to 60%. The QL120 and LL140 fans are at 60% to 70%. No more buzzing and resonance issues.

The 4090's size is pretty ridiculous.

My 3090TI is insane. Here is a comparison to 3080TI and 2080TI. I doubt its bigger than my 3090TI

Just opened my new 3090TI, holy cow ! Look at the size !

This pic shows 4 different cards I have not currently running. A 2060, 2080TI, 3080TI and at the bottom my new 3090TI. Its over 3 slots wide !!! And it dwarfs a 3080TI above it !

Heck yeah it is!!! It fits fine in my Lian Li case, but I can't use my crutch to hold up my 4090, because I have fans at the bottom of my case. That may change though. I figure that I give it a week or two and see if my 4090 starts to hang low.

Isn't that reckless? The slot could get damaged.

 

[Muadib]

It appears fine right now with no hang. I can see the 4090 due to the glass side panel.

It's not the hang I would be worried about. The part of the card that fits into the slot, it's really thin. It might resist the added stress up to a point and then it might just snap off, stuck inside the PCIe slot while the card falls...

Nooo! The screws hold the 4090 quite firm. If it's going to move, it will be in the inside the case where it's not screwed down.

 

[Markfw]

Isn't that reckless? The slot could get damaged.

My 3090TI (pictured in the link above) has a HUGE backplate attached to the PCB right next to the slot. This makes the card very rigid. with the screw (or screws, it allows all 3 slots), it is very solid. I imagine the 4090 is built the same way.

And you would be correct! I don't think the card is going anywhere, but if I see any movement my bottom fans are coming out, and I will attach the crutch.
