Threadripper BUILDERS thread

[ub4ty]

Well, after $3500 on this build, kind of maxed out for the moment

I hear you. My wallet is empty and I left lots of room for expansion of its full potential down the road.
That being said, i made sure to lock in quality parts along the way.

While the heatspreader effect won't be fully quantified until folks can do back to back tests (with the same chip) using different heatsinks, we can make a bit of a guess.


AMD have used indium solder onto gold plate onto the main heatspreader which is primarily copper with a Nickel plate on top.

So,
- The solder has a thermal conductivity of 80 W/mK.
- The gold has a thermal conductivity of around 300 W/mK
- The copper has a thermal conductivity of around 400 W/mK
- The Nickel has a thermal conductivity of around 90 W/mK


Good thermal paste has a thermal conductivity of around 8.5 W/mK.
Intel's TIM has a thermal conductivity of around 6 W/mK.

http://www.techarp.com/articles/delidded-threadripper-secrets-revealed/


Now, lets assume that the heat will pass through the gold/copper/nickel mix. Because the copper is most conductive, we will further conservatively assume it passes only through the copper - which we'll assumed is 1.25 mm thick in an IHS of overall thickness 1.5mm.

If we further assume only 70% of the die has normal conductance through the heatspreader to heatsink then the average distance the heat must travel is approx ~.0042m (based on full diameter of 51.9mm to enclose all 4 dies and thus 43.5mm dia to cover 70% of die area).

Take the conductive area as the circumference of 43.5mm cylinder with thickness 1.5mm and for copper you get a thermal resistance of 0.16 K/W.

Then, with 30% of 180W passing through this, the outside corners of the CPU dies will see a temperature rise of between 10 and 17 Kelvin (worst case scenario since we haven't added in the nickel or gold or indium solder).

Given that reviews are recording TR temperatures ~65degC at stock and ~80-85degC on overclock, and compare that to the Intel Core i9s... I don't think the TR heatsink/heatspreader incompatibilities are much of an issue.


[Saturation should be a non-factor as the heatsink will be continually extracting heat from the system and the overall thermal gradients should be large enough to render the localised effects rather minor.]

But what about uneven thermal expantion ?

I saw a number of reviewers with 8 banks filled. Not sure if they bothered to disclose any issues they had in such a config (*sigh.. the state of the review scene). Anywho, hopefully someone here drops ~$700 on ram so we can find this out so we can start probing memory limitations

That would be me.I want quad channel damn it.

You only need 4 DIMMs for quad channel.

You only need 4 DIMMs for quad channel.

:-O

Edit: Actually I am planning on running some hyper-v VMs while gaming at 1440p with everything fully maxed out. I currently run a hyper-v server on a FX-8350 with 32GBs of RAM and it kind of sucks a bit. It will become a full time media player/server. I think that TR with 64GB should rock my socks off.

Of course I might change my mind and not do that at all. Time will tell.

OMG, I didn't realize that the free shipping at newegg (3-7 day delivery) had Saturday delivery ! But my threadripper is on vehicle for delivery ! Yea ! Benches today guys

 

[Pick2]

Woo Hoo ! no more waiting for your hard won reviews !
( We love to see you work up a sweat )

 

[Markfw]

Well, crap... I was talking to a neighbor, and he gets more shipments than me. So here is the story. Fedex loads the trucks on the weekend for Monday. My chip is on the truck, but no one is driving the truck until Monday ! Hence the estimated delivery date of Monday.

Sorry, no reviews today !!

 

[urvile]

I must be driving the folks I am purchasing my hardware from nuts. I decided to half my RAM to 32gb (4x8gb @3000mhz) I am thinking 64gb was overkill and that gives me 450$ to put towards my new graphics card. Which will most likely be a gigabyte gtx1080ti AIO set up.....

I didn't see a price, but my config beats that one by a mile, mostly memory. 2400 ? and I have 3600 ?

If you are already paying $8K for a system, then the processor price argument goes away for the most part.

OK, I have my threadripper installed, upgraded bios to 1.3 on the Taichi, but my win 10 USB installation stick that worked on my 1700 and 1800 just sits there after about 10 seconds, and does nothing.

Any ideas ?

I am making a new win 10 USB stick right now in case that one went bad.....FROM Microsofts web site.

Edit: And in case there is any doubt of memory creating a problem, I am running it using the XMP profile, but at 2133.

Edit 2: The new USB installation stick is installing windows now. Maybe it went bad ?? Up in a few minutes I hope and ready to start benchmarking.

So what FREE benchmarks can I run ?

The usual Cinebench, Firestrike, etc. You know the drill, Mark.

 

[wildhorse2k]

Get DDR 3600 working then run AIDA64 memory and cache benchmark.

 

[Markfw]

Actually, I DON'T know the drill, EXCEPT Cinebench, dying to see that at 3600. It booted msany times at that, until I found the install stick bad, I was at a loss. Thats Ok, I have a new updated version, and updated bios.

I will have to download AIDA64, and I know nothing about the firestrike benchmark, care to save me time and give me some links for both of those ??

I got a 1950X, 128GB of Corsair DDR4-2666 on the Asus Zenith.
Using the AIO adapter on the Thermaltake 360.
Not sure what to think about this. 50C idle is off, same +20 bug as Ryzen?
In any case, left everything in AUTO and put multi at 40.
Windows shows 4GHz.
Cinebench 15 at stock was just over 3k.
Cinebench 11 ROARS until the last few tiles and it slows, score is 20000. WTF! Acts like something is throttling.
WinRAR as expected is terrible like Ryzen, about 1/4 of my 6950x...

Love the size of the CPU and (finally) LGA on AMD!
Reminds me when I got my first Pentium Pro 200 over 20 years ago!
And like that chip, some things just aren't taking advantage of its capabilities.

EDIT:

HOPEFULLY EK will release a FULL COPPER Supreme TR4 series block with cold plate and FULL finned area covering the ENTIRE CPU!!! These current AIOs are a compromise for sure. If EK won't HK probably will as long as it's not a $400 pure silver version.

OK, everything@stock, but memory at the stock 3600. Results 31380 here: https://browser.geekbench.com/v4/cpu/3704092

How is that ? Aida64 next

Why does amd perform so poorly in geekbench? We all know the MT performance is there, why does it not show?

How is that ? and a link to firestrike ?

Excellent memory latency, probably the best I've seen on any Ryzen. I guess the secret is 3600 freq., four channels, and 2 memory controllers, heh!

The GB4 benchmark doesn't seem to scale well under Windows to large numbers of threads, so the multi-core score isn't a very useful measure of performance, imo, but the single core number is very strong. I suppose the single-core portion got seriously turboed at the stock settings.

Has anyone's MSI board actually shipped yet?
