Hi guys,

I used to build PCs and OC them etc but last time I did that was in the mid 2000s. Think AMD Barton/Throughbred time. Anyway, recently at work needed a much more powerful workstation for crunching large amounts of data and the gaming laptops we had in the office were simply not cutting any more. So I thought I could just wing it and put together a system to do the data crunching. A rough outline of the build is

CPU : 7950X
MB : ASROCK X670E PRO
GPU : ASUS RTX4070Ti
SSD 1 : ACER Predator 1TB PCIE4
SSD 2 : ACER Predator 2TB PCIE4
Casing : NZXT H9 Flow
RAM : KINGSTON Fury Beast RGB 64GB (32x2) x 2
PSU : ASUS 1200W
CPU Cooler : NZXT Kraken 360 RGB Black

The PC works out of the box and I am aware of the fundamental behaviour of the newer CPUs where they push power and clock speeds till hit max temp then throttle back but there are a few things that I am unsatisfied about. Hoping to get some pointers here

1) Its not the temperature of the CPU that bothers me, in fact I am expecting it to hit the 90+ deg C level but its how fast it reaches it. I tied the cooler fans and pump speed to the CPU temp so basically once its more than 60 deg C, the fans and pump are running at full tilt. Coolant temp never exceeds 32 deg C but the CPU reaches 90 in a very short time (like not more than 10 seconds). This happens only when I am crunching data. Could it be due to insufficient pressure between the pump and IHS? Or insufficient thermal paste? I just left whatever the came with the cooler on it and just used it.

2) I tried using the Ryzen master to try to come up with a profile. It came up with a -40 profile but once applied, the system would never boot up. So far I used a less aggressive number like -10 and its stable so far. I find that the temps still rocket to 90+ but just not so fast and it can hold all the cores at about 5.450 GHz about 50% longer. is there a detailed guide on how the voltages and clocks relate to each other. Its so confusing relative to 20 years before where it was just FSB x multiplier

3) I have all the RAM running but I can never get it past 4000 MT/s. I know I made the mistake of not making sure the RAM was AMD expo certified. Is it possible to manually push the 4 sticks to at least 5200 speeds?

Just hoping for tips for troubleshooting and if possible any guides for modern system overclocking/tuning. I prefer PDFs to YT videos (old school mah)

I think the bro here ady has the system but needs help getting EXPO working, thats all 

Thanks for the link. Will go through it slowly later.

Like Babylon said, the system is working. It's just I want to try and fine-tune the performance as I am using the system to do map processing. I roughly process about 100k images at a go resulting in chunks of maps about 30-50gb each. So I am hoping if tweaking the system a bit will improve the performance as typical processing time for one block is about 5 days non stop so every little bit helps.

Care to explain a bit more? I mean it would be good to know what kind of problems he is facing till he surrender

Something like a rendering farm but for data from drones.

PCs get faster all the time. They also become more efficient every few years. Plus cooling system wear and tear. We decided to shorten life expectancy for machines to 3 years

No thanks. Used to be running on a precision cluster. The machines were ok but the fact we couldn't tweak more performance out of them made me a bit annoyed.

So far the stability is something that is understood and can be solved. Actually dell also has precision with AMD. Just not sold here. A friendly company who does the same software processing in the states tested and Vs intel and prefers AMD so we follow their recommendation.

Also I don't know why your experience with amd is so bad. Mine after a bios rest has never taken more than 10 minutes for a ram relearn and my interns made mistakes in assembling resulting in a slower machine. Slow but stable. Even when they forgot to connect the main connector into the heat pump block on the CPU, the system just immediately shutdown. But nothing as chronic as what you described.
