Has anyone else hit a pciex device limit using the am4 platform, my systems listed but essentially a 3800X on a crosshair7 with a gpu and 3 nvme drives, if i add one more pciex device, nvme or gpu it has a no boot looping fit.
seems like a 4 device limit?.

I have 2 nvme and a sound card, no issue...

So that would be four, same as me , I can do four it's the fifth.

Which slot is the one having trouble (5th device)?

C7H is a X470 board so there's a helluvalot of wack bandwidth sharing going on. 3.0x8 GPU, 3.0x4 M.2_1, 3.0x4 M.2_2, 3.0x4 for the third NVMe.

Assuming that's how your 4 devices are laid out, then all of them are on the CPU's lanes, but the 5th has to go through the chipset. The 2 2.0x1 slots or the 2.0x4, all go to X470.

I think there are some PCIe devices that don't play nice with chipset lanes, could be the case here. In any case, the design as it is shouldn't be lacking enough lanes to run the devices.

I've tried about nine different things(a few gpu and four nvme and all worked fine if i took it out of one of the other pciex slots9ie so the total is 4)) and can use the lowest pciex that runs off the chipset, im not but anyway i cook it, it is the fifth device, ive been at this for months before posting anything.

My MB tells me if I get a third nvme I lose the 5th pcie, and it's X570, you might've run into board limitations...

I would have suggested to take a look under Onboard Devices Config in the BIOS, but I took a look at mine to find it only really adjusts PCIe gen bandwidth.

The only other thing that I can think of is that the only block diagram for C7H that I can find seems to show 10 2.0 lanes coming off the X470 PCH when it only actually has 8, because two of the lanes appear to go to an ASMedia controller for some rear USB ports? But that would make no sense, it doesn't show a PCIe switch anywhere, and Asus would write about it if there was bandwidth sharing.

Any differences with other BIOSes?

That makes sense for X570 if the second 4.0x4 NVMe coming off the X570 chipset is tied to a switch with the 4.0x4 x16 slot coming off the chipset, so you can only use one or the other. On the C7H, both x16/x8 slots come off the CPU, both M.2s come off the CPU, the only things coming off the chipset are the 2.0x1 slots and the remaining 2.0x4.

I think I read it somewhere but it wasn't an official source I'm going to try some bios tweaks regarding pciex ARi settings or something like that.
One last try, probably not really tho.

I don't run Sata drives because they take pciex bandwidth and asmedia is disabled , I have run with them on and it still works but it does take bandwidth.

Oh and one nvme, unused is off the chipset on mine.

I just tried Linpack Xtreme 1.15 and it is zesty! Backed my oc down to 4.4 unless 85c is ok, and if that’s the case I’ll turn it back up

This is what I get

 

[Mussels]

So I been playing with my 5800X and set PBO and Curve Optimizer. I'm now seeing 5GHz Boost across cores on my CPU

Anybody here have a 5800X i can compare test results too

Me. i was getting 5050 on all cores, but now they sit in the 4900-5050 range on the latest agesa

pretty sure this is with eco mode on

Looks like you'd be the first to post benchmark results for the 5800X in the Cinebench thread. There's nothing in the first post chart.

Hey guys.. noob question..

How do you change the memory controller clock on my board? I've checked everywhere in the bios and cant find it. I have my IF clock at 1900, so my ram is at that and the memory controller is at that. But if I change ram speed to 4400 the mem controller drops down to something like 1066 from 1900. I don't recall exactly. I can find 2 out of the 3 speeds that I need to control

I just need to fine tune that one aspect and I will be happy

Should be really easy for Asus. On the main Tweaker page, should be an option for Infinity Fabric clock directly below memory speed.

Called FCLK frequency. Order on that page is like DOCP, BCLK, spread spectrum, APE, memclock, IFclock

Probably also options for dividers buried somewhere in CBS or AMD OC menus, but those are messy and why do that if its right on the tweaker page

BIOS also has a search function F6 i think

 

[freeagent]

I must have my beer goggles on On the main tweaker page I just have IF and Mem clock options. It must be buried in that mess somewhere. This bios has a few more things then my Z77 lol. I figured this would be similar to X58 to OC. Maybe instead of 1:1:1 control, maybe I only have 1:1. Its crazy that this 1600MHz ram can do 2200MHz, don't know how stable it is.. no point in running it if it performs like 1600MHz ram

I thought 2200 16-16-16-36 would have been saweet!

Probably not stable.. back to 1900/1900

This should be it, but if (I don't recall Asus having this problem but I could be wrong) it forces non-1:1 IF to strictly 2:1 then you may have to dig into the CBS or OC menus to find the dividers section:



I needed somewhere in the ballpark of 1.8V to bench my 4400 16-16-16 1:1 result in AIDA, on my 4650G. Even with decent B-die you're probably looking at somewhere around 1.65V at the very very least.

If sticking to 1.5-1.55V max, 4000 or 4133 16-16-16 is probably a better bet for a stable daily setup, but you don't have a Renoir, so the performance just isn't there above 1900MHz IF, pretty pointless.

This is what I get

Did you note your PPT? At 6200-6300 that's like 160w in R20.

Ofc it shows it. Look under CPU power package SMU, below CPU EDC. Stock 5800x will run up to 140w +/- giving just over 6000.
