Corsair MP500 M.2
nVidia GTX 980
Corsair HX1000i


Clock Speeds

Our new retail sample is significantly hotter than our Engineering Sample was, and that has an obvious effect upon the overclocking capabilities not helped by the fact that the CPU needs the same amount of volts to hit 3.8GHz that our Engineering needed for 4GHz. Our methodology has always been to overclock the whole CPU rather than a single core, and with the Threadripper 1950X although you can get good performance (4.2GHz) up to four cores, the moment you pass that the thermals become seriously prohibitive, hence we'll just be comparing stock for stock today. Most programs perform better with the 4.2GHz boost its only the heavily threaded apps that dont but when its only a 200MHz boost across all of the cores is it really worth an extra day testing the OC? When weighing it all up and seeing certain programs actually performing worse (3.8GHz<4.2GHz) we decided it wasn't.

So forexample: Streaming, whilst Video Encoding and Gaming would be the "Manual OC but not as High OC" category? Or would it be better to let the Processor decide which of these applications might need a boost at the moment?

Nice Video!Quote

It's always best to OC yourself.Quote

"is capable of matching anything you bring to the party" - not compared to Xeons or even EPYCs though.Quote

I also have a a 1950x and a Corsair H110i GTX for almost a month now. I am able to get stable OC at 4.1Ghz but not 4.2
The only reason for that is the AIO can't cool down the CPU.
I will do some tests whenever I get a cooling solution designed specifically for Threadripper. I hope TTL does this as well because the whole results are going to be different when we are able to overclock.Quote

Hey, long time listener first time caller. I have a 1950x rig and I am Prime 95 stable at 4.05 GHz on Noctua's TR4 NH-U15 with 2 140mm fans. Volts are set at 1.4 and although it gets to 85C in prime I don't see it get passed 75 unless it's a really hot day under regular load. I have a lot of airflow in my Thermaltake View 31 case though.

I compared the round Acetek cold plate to Noctua's design

I found that a 240mm AIO was no match for air cooling with the proper cold plate design. Enermax is sending me their TR4 360 AIO and I am expecting it to allow me to push things a lot further. I think AMD really should have had the big boys on board, Corsair, Thermaltake ect to design proper cooling rather than just suggesting you use the round cooler.

Anyways. I think Threadripper is actually better suited to overclocking than Ryzen 7 was now that the silicon has matured and it won't be crazy to see 4.2 GHz stable on all cores with a proper interface and custom cooling.Quote
