Modeling and Gaming Build

[Climbku]

Here is my setup. I run modeling software and also enjoy gaming. With 1 420 and 1 360 rad (6 fans in push/pull for the rads and 13 case fans) I have lots of cooling. Because of this I am not sure if I should run PBO + 200 (R23 37000 and 1300) or 4.4 Ghz on 21 cores and 4.5 on 3 cores at 1.35 volts. (R23 38300 and 1275) Port Royal at 11550 for both ish. What does everyone think? I save for power with PBO + 200 at normal use. Any guys with 3960x's what are your overclocks looking like? 

Hardware:

Corsair 1000D

Zenith II Extreme Alpha
Threadripper 3960x @ 4.4 All core 4.5 3 core @ 1.35 volts OR PBO 10X (600w 400A 600A) + 200 all core usually 4.3 in heavy workloads and single core (3 cores) 4.566 Ghz ~ 250 - 300 watts

Red Devil 6900xt ultimate @ 2700 GHZ at 1141mV and 400 total non transient watts

64 GB Ballistix 4x16 GB Micron B die 3600 CL 16 @ 3733 CL15 1T (1:1 W/ Fabric) Could not go higher on 1:1 with Infinity Fabric so all timings are very tight instead. BK16G36C16U4WL M8FB1. If anyone is interested I can post all timings.

2x 1TB Samsung 980 Pro

Asus Thor 1200 W

Optimus Absolute Threadripper 3+ Water block

EKWB 6900xt water block

AOC Agon 49 inch

Newfypoo (Newfoundland x Std Poodle)

Nice system, good dog. Pretty respectable RAM for a Threadripper system.

If you want to, there is a way to unlock voltage control on those cards through software. Those cards do scale with voltage pretty well if you want to get another 150-200MHz out of that card.

Would it be the same software I used to increase my power limit? I figure I have the thermal room to go a litter higher. Reading your posts, you seem knowledgeable in ram and timings. I'm stuck at 3733 if I want to stay 1:1 and that's the limit my threadripper silicone can handle. I have the 16GB Micron B die CL16 sticks. Should I be able to hit CL14? 3733. In your opinion is 3600CL14 better than 3733CL15 provided I can hit it? The Photo shows with gear down enabled hince cl16 and 3733 so I assume when I run CL15 (GDM Disabled) I am slightly better.

Yeah, there's a way to do it with MPT. 

Running my card at set 1.25V compared to the stock 1.175V got me an extra 150MHz stable (2550 compared to 2700 on a Red Devil 6900 XT non Ultimate).

Threadripper is the one Ryzen platform where it actually makes sense to run outside the 1:1 limit for a lot of situations. The main disadvantage of running outside of 1:1 is that it adds another ~20ns of latency to the memory. On Threadripper though, where your latency is already crazy high, that's not really that much more, and if you're using Threadripper odds are the extra bandwidth you'd get running something like 4400MHz CL18-18-18-40 would be pretty beneficial.

You should be able to hit 3733 CL14 given enough voltage, though Micron 16Gb Rev.B is fairly temperature sensitive IIRC so running it next to a 300-400W CPU might not be possible. 

 

Running true 1T command rate is pretty impressive though, I've yet to get that stable on any kit of my kits of B die (I've booted a couple of times but it always fails stress tests).
