Blackbird / Blackbird memory options...

« Last post by surf on May 21, 2020, 04:15:19 pm »

So the manual for the Blackbird doesn't have much to say about the memory, besides:

DDR4 1600/1866/2133/2400/2666 ECC

The wiki says more:

must be registered (RDIMM); must NOT be LRDIMM.
The supported memory speeds are 1600, 1866, 2133, 2400, 2666 MHz.
Ram will be running at a potentially slower frequency (2666, 2400, or 2133) based on if there is 1, 2 or 4 DIMMs per channel

So as a noob to this stuff, what is a good approach to picking RAM for the Blackbird?  For example, would 2 8GB sticks be better than a single 16GB?  Or is it better to leave a slot open for a future upgrade?  How much does the speed matter?

Blackbird / Re: How many fans per FAN header?

I'd guess an amp would be about as much current as you want to pull through a regular header pin.  If your fans are high power, you could always source the power straight from the PS and the PWM signal from the fan header.

I've used a single splitter without problems. I think it would get dicey chaining more than that.

I think a better means is to try to create a VM in QEMU directly. I think you have too many layers in the middle to verify functionality. Try this: https://www.talospace.com/2018/11/making-your-talos-ii-into-ibm-pseries.html

If it boots AIX (fast) with KVM on, then you know it's working, and the other issues are most likely related to configuration.

In any case, I wrote directly to them, through that link that posted the friend TLE, I joined the Fedora group and I sent a post to explain the problem, let's see what they answer me. It is always useful to be in contact with them for this and other possible bugs that will arise and will also explain to them the problem encountered by dnfdragora ...

The Kernel is the same no matter which Fedora version is in use.

MPC I'm talking about the Fedora 32 kernel. If they say they have included the Navi 10/14 patch in the new Kernel, does this mean that the new Fedora 32 kernel must also work or am I wrong? What's the point of inserting a patch if you don't notice that there is a bug and you don't even fix it? I'd like to apologize ... Fedora 31 leave him alone right now. I also use both the modified Kernel 5.5 and the modified 5.4, both have the patch without bugs, but I would like to use the current kernel since they have inserted the patch on that too ... Obviously the correction that Daniel did, they did not still not even looked ...

I don't know what your problem is, but the Kernel (Fedora 31) works. Thanks again to q66.

Blackbird / How many fans per FAN header?

« Last post by tle on May 20, 2020, 10:41:48 am »

I am planning to revamp my chassis cooling so I am wondering how many fans could I split from one fan header? There is no mentioning how many amps per fan header in the service manual btw.

Much thanks in advance

Tried Kernel 5.6.13 and this doesn't work either. It ends up that at this rate it will never work if someone does not tell the Fedora team that this damned Kernel has a bug in the management of the Navi10, it is not normal that you put support for a graphics card and then you do not solve a small bug that it doesn't make it work, you might as well not put it on the PAtch ...! I will also try to write to that address that Tle posted to see what they answer ...
