i can tell u.. the problem wont END.. my client still run mission critical machine with intel.. AMD screw up on n off... especially if u run on win 11

On the positive side, it appears that Ryzen 8000 series seems to like much higher speeds DDR5 and since AM5 is forward upgradeable perhaps your other hope is upgrade to a 8950X (when it comes) and hope its IMC is much better at taking 4x sticks of RAM to be stable at higher speeds. Just my 2sen.

Luckily for me this machine was asked to be put together by a client and I use to process his data. Later will have to give him back this machine when the project is over. I was using this to see if I should go with consumer CPU or something like a threadripper for own purchase

If you doing prosumer/ professional work application stuff, you really shouldnt be mucking about with OCing or EXPO/XMP stuff. If you want 5200MHZ you really should be getting RAMS rated at its JEDEC speed to 5200MHZ.

They are jedec at 5200........when only 2 sticks. If you look at the AMD Ryzen website for all the 7xxx CPUs, the CPU is supposed to run 2 sticks at 5200 and 4 at 3200. But I have also found people having success at getting their systems running 5200 with 4 sticks. Not without getting some work done though. And sorry for sounding like some old faggot but having more than 20 different voltages with no proper description in the bios and in the bios manual doesn't help me tweak what I want to tweak safely.

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

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)

If you want max performance, you will need 420 or 480 aio and casing that can fit it. Custom loop water cooling for even more performance. There is direct die cold plate (will void warranty) as well.

Are you running quad DIMMs?  Quad DIMMs can be a pain to run properly, even buildzoid actually recommends going only with 2 DIMMs on DDR5:

Sorry if unhappy to unnecro an old thread. Just an update. Updated MB to latest AGESA (ComboAM5 1.1.0.3)

Now able to hit 4800MT/s. Basically I have set the timing parameters to match XMP @ 5200 so the CAS and other timings set to match the XMP values even the voltages. But only difference is I have set the clock speed to 4800. So far stable running all banks firing meaning the RAM is 100% utilised and have been running for about a week non-stop. Once current batch of data delivered, I will see if can push to 5200.

Clearly you are really not informed about latest hardware.
Intel 13/14th Degradation even on STOCK Setting : https://www.google.com/search?q=intel+14th+...nt=gws-wiz-serp
4090 still melted at 75% power limit
https://www.tomshardware.com/pc-components/...ing-at-75-power

Setting to stabilize your 7950x.

Undervolt. Downclock.
~-5% overall perf.
but temp stay under 60


Most Top END hardware today work intented within warranty period. 1 or 2 years.

Thats all.

Stock setting = crazy setting.

That's ok....we calculated costs with intention to amortize the machine in 2 years. So in 2 years we should already ROI this machine and anything extra is bonus. I just want to extract the maximum performance from the machine to increase profitability. More data I can process in this 2 years means make more money.

what are your usage?
rending farm?
if -10% peak performance, but last another 3 years.
i think that only consider "Optimized"

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
