We aren't talking about the

We aren't talking about the gateway address of the router.  We are talking about the addresses handed out to all your devices in the prescribed DHCP address pool.

Open up the router Web interface at 192.168.0.1 and look at the list of clients that have been assigned IP addresses.

Look for the MAC address of the BMC interface to see what IP address it has been assigned.

You need to look at your router first before doing anything. Find the BMC IP address. Then use that address to login into the BMC web server.

If you have screwed things up beyond repair, then use the BMC management menu in the BIOS to reset the BMC to factory settings.

You can always get the external gpu to show the boot sequence with the BIOS set for External GPU if you put the gpu in slot 1, PCI BusID 1, which is the slot at the bottom of the board.  That is what External GPU defaults to until you change which external slot you want later. So put a gpu into that slot, boot into the BIOS and then change to slot 7 or whatever and save the BIOS. Then move your gpu to Slot 7 and you should see the boot sequence on that card.

Lets say you buy an QS sample

Lets say you buy an QS sample of a 7742.  The listing promises 1 missing memory channel but it looks like you have 3 missing.

Inspite of that you have two sticks of memory in symmetrical locations.  2nd slot from the CPU on either side.

And you have enough memory to run all 128 threads on projects like U@H/WCG/TN-x

I can also run a memory stick on the "top" side of the CPU either next to the CPU or in the 3rd slot.

And I can also run a memory stick on the furthest away slot on the "bottom" side of the cpu.

On theoretical grounds will adding any of those memory sticks "speed things up"?

I would run 6 sticks for a 6-channel configuration. 4 is probably fine too.

Since you only have a Boinc reported 64145.57 MiB amount of memory in the machine right now I would think the short answer is yes. The long answer would depend on how many cpu cores you want to use, ie all 128 or some number less than that, and the memory requirements of the tasks you want to run and you need to add in the 1 to 2 gb of memory just for the OS overhead. You said you can already run all 128 cores at 3 different projects I'm guessing you know you are memory limited at other projects, maybe even this one as well, so yes I would do it if I already have them anyway. Even if you don't get the memory channel speed-up more memory is not a bad thing.

Mikey, I posted that

Mikey,

I posted that question shortly after I got my missing 1 memory channel 7742 CPU. And it had 3 missing.

After I cleaned the bottom of the cpu and reinstalled two of the missing memory channels reported for duty during POST.

So I wasn't forced to try out the memory chip wherever plan.

I now have all four nearest to the CPU slots. The one non-working slot is on the far outside.

Which means I could bump it up to 6 out of 8.

It is now using about 25 percent of the available ram.

The load is 4 gpu threads (e@h), 8 TN-Grid, 8 WCG and 96 universe at home CPU tasks.

The interesting thing is this references Einstein at Home.

And the id info it lists is not mine. And there are no other candidates in the top 50.

So where/how is the reporter finding the info? Or is he reporting unsubstantiated rumor as fact?

I saw this too. Or, the person who "found it" is also the one testing it? Either way, interesting that this showed up. It still looks active based on when it last contacted the server.

We've had people testing new cpu's here at Einstein in the past, one person is a member of the GPU Users Group, I think, and gets Server type cpu's often with close to or more than 100 cpu cores.

I am confused.

Mine is "type:AuthenticAMD AMD Eng Sample: 100-000000053-04_32/20_N [Family 23 Model 49 Stepping 0]"

The referenced one is "AuthenticAMD AMD Eng Sample: 100-000000454-20_Y [Family 25 Model 24 Stepping 1.."

Where are you finding the referenced one?

Thank you.

I think Mikey is just confused about the Eng Sample designation. 
 

Tom has an OLD ES. Not a brand new one. Very often ES chips make their way out into the wild after retail chips have been released. Sometimes they have bugs or defects or slightly different features than the retail chips and are usually a bit cheaper on the second hand market. That’s usually why people buy them, cheaper.
