Precision 7550 & 7750 Owners' Thread

Regarding the CAS latencies, I am trying to get a howto on Ubuntu. Not quite as easy as with CPU-Z in windows !!!!

 

I'd suggest to do what SlurpJug did then. My response was basically passing along what I have heard from Dell in the past (and it confounds me if they have split up the channel between the two sides of the motherboard), but I will admit that I have never actually tried it, I generally just use configurations where all of the modules are identical. For CL, if it is tricky to find in Ubuntu, it might be simpler to figure out the memory module model number (physical sticker on the module?) and then look up the specs online.

 

Thanks Aaron. I'm also surprised why they would split the channels ... it would be very unconvenient !!!
I think I can get the Part Number from Ubuntu and look on the internet for the latencies !! Thanks for the tip !

[Edit] : RAM is
HMA82GS6DJR8N-XN - SK Hynix 1x 16GB DDR4-3200 SODIMM PC4-25600S Dual Rank x8 Module
CAS 22 - 22 -22

 

OK ... it looks like both of the Crucial modules that you listed are also CL 22 so you should be good there.

[Edit]
Not sure of your location but I noticed that Newegg has these modules for sale at a price that looks reasonable to me...

That's nice ! But I'm in France. Not sure the shipping cost would make it worth it.

 

I can't enable keyboard backlight however in BIOS I have this option. Does anyone run into the same problem?

 

I bought two of those for total 128GB.

I'll get my 7750 next Thursday. I'll know then if it'll work.

 

Damn' ... 128GB ... What a monster machine !!!!

 

Hey guys, I have a 7750 that is pretty decked out. Top Xeon Chip, 128GB ECC RAM, and i moved the OS over from the 1TB class 50 to a 2TB Samsung Evo 970 Plus. I also added a second 2TB 970 Plus, a Sabrent 4TB, and I kept the original as an extra onboard drive. I have the RTX4000. However, from the time i got my system, my computer has not gone to sleep. When I try to put it to sleep, it just takes a second and then goes back to the lock screen. Really Really annoying. I have tried everything, from the powercfg solutions to power options to even attempting to contact Dell, who was less than helpful. Ultimately, they are going to replace the motherboard. I've reviewed some forums that say the video card might be the issue, there is a similiar problem with the RTX 2080 but with that issue people are able to put their system to sleep after they go into power options for the Nvidia USB-C Policy Port Controller and not allow it to wake the PC. For me, even when i do that, it won't go to sleep. Besides this issue, the system is perfect. It was an upgrade from a 7520 that was decked out and its a noticable jump in performance. Anyone have any sleep issues with their system, and if so, any solutions? I'm just trying to figure out if this is a common issue. I know many users like to shut sleep off, but I like to leave it on at night at my office and just put it to sleep.

 

Maybe not a solution, but wondering if you run any VMs on this system? My system behaves like this if I try to sleep it with VMware Workstation running a VM but it sleeps normally if I suspend all of the VMs.
