AMD Threadripper 3970X and 3960X Review: High-End Domination [emoji23]
Sent from my SM-N960U using Tapatalk
My intention is to build a 3970X cruncher. Maybe some mild OC, if any. I could use some advice.
- Looks like there are about 10 mobos available now, roughly all the same cost, ~$450-500. Maybe more by the time the CPUs are actually available. Any obvious favorites or things to avoid?
- For memory, I would want at least 2gb/thread. So 128gb. I see it is quad channel, and that means either 4 or 8 DIMMs. Either 4x32gb or 8x16gb, and 4 is faster than 8, right? Also, it supports up to DDR-4666, but that is crazy expensive and I am not finding anything larger than 8gb DIMMs on newegg. For 32gb, it looks like the fastest speed is 2666, at ~$600 (for 4x). For 16gb the speeds range 2666-3200, and cost starting at ~$500 (for 8x). With no intention to extreme OC, what is the sweet spot? Or maybe I am missing a better/faster alternative?
- CPU cooler suggestion? No custom water cooling, please. Either HS/Fan, or all-in-one.
- Finally, I want to try out PCIe 4 NVMe M.2. Normally, I would just go with Samsung but they don't have a PCIe 4 version yet? So who else is the favorite?
mobo: depending what you want to build the rig for. Dedicated cruncher doesn't need all the belt and whistle so I'd aim for lower tier ... which is still around $450 - $500. Higher end is around $700 i believe. My choice would be either Asus (Prime) or Gigabyte (Master). I avoid MSI because of bad experiences and i just don't like ASrock bios. I'm leaning toward Gigabyte Master because of the VRM heatsink.
memory: definitely go 4xwhatever ... don't go 8 dimms (daisy chain). so 4x32 for your case. 3600mhz is what you need, higher doesn't make sense with the way Infinity Fabric works. Infinity Fabric works best when it goes 1:1 with Dram speed and cap out at around 3800mhz. So no need to buy Dram higher than that. Hell, 3200mhz with tight timings works almost the same with 3600mhz.
CPU cooler: You probably need a high end AIO. NZXT Kraken X72 for example. I just bought a deepcool castle 360ex aio, I'll test it on my 2990WX to see how it goes and report back. But I heard it's neck to neck with the NZXT.
NVME: no comment :D I'd like to try it myself, but I probably will wait. Because there are more potential for more speed. Right now, it's not at peak speed yet.
Thanks for the feedback!
Follow-up: What is "tight timings"? I know that memory has x-x-x-x ratings, but I am ignorant as to how they relate. I gather that smaller is better. But what is "tight"? And how tight is tight enough?
yep, smaller is better. Basically just think of it as overclocking ... but instead of cpu, you're overclocking Dram. There's a tool for that called Ryzen Dram Calculator or something
https://www.techpowerup.com/download...am-calculator/
the tool will take info from XMP and give you suggestions what you can do to improve.
There are a few steps to gather info from your Dram and plug them in the tool and it'll calculate and give you what you can do.
First you'll need to download Thaiphoon Burner http://www.softnology.biz/files.html Freeware version
Run it, find out if your Dram is 1 rank or 2 rank. Hynix or Samsung etc etc .. B-die or not.
Once you see those info then just plug them in the Ryzen Calculator and it'll give you the Safe timing or Fast timing ... whichever you choose. Take a picture of that screen and go to your Bios and insert those values.
Search youtube for Ryzen Calculator how to ... to have an idea.
And that will tell me which DIMMs to buy? I'm confused.
no Z,
each set of memory comes with XMP profile right? The tool (thaiphoon) reads that profile and give you information about it. Like timing, voltages, vendor's name, type.
you take those info and plug them in the Ryzen calculator, then choose calculate FAST. It'll suggest a new set of timing (tighter).
For example: I have a set of 3200mhz Corsair LPX in my machine. Beside that I don't know anything else about it
Ran Thaiphoon: It will then spits out some info like they're 1 rank modules from Hynix , and they're not B-die. 16-18-18-48 at 1.35v
I then run the Ryzen Calculator: it will ask for those info
Plug those info in and choose calculate Fast.
Ryzen calculator gave me a new set of timing: says 14-17-19-26 at 1.39v and a bunch more of sub timings.
Copy that and go to the Bios and manually enter those values.
Sorry for the confusion! My english is aready bad enough, my explanation is even worse lolol
Got it. Thanks!
Like VO said,avoid MSI. Many BIOS issues and patches seem to lag behind others. Gigabyte Aorus (any model tier) is the way to go this gen, going by teardowns and build quality analysis. The Asrock Taichi would be my 2nd choice. Definitely 4x DIMMs but not Corsair. You want Samsung B-die so go with G.Skill. Also like VO said, there's no reason to buy any kit over 3600Mhz. You can OC to hit 3733 if you just really had to [emoji14] Personally I'd look for a 3200Mhz kit @1.35v or less and OC that.Quote:

Edit: G.Skill has announced kits up to 256GB but they're not released yet. Should be very soon.
@John what about those Crucial E die kits? Do you have any info about them? I heard a lot of good things about them but I haven't pull the trigger yet
They can clock higher than Samsung but no one needs 6600Mhz+ RAM lol. I remember when they set that record and a few of us were studying their settings and it turned out to not even be useable. But they broke the record I guess. Samsung also can have better timings out of the box. But overall it's not bad, especially if the price is right. Too bad they don't make 32GB modules.Quote:

I have Crucial in my Xeon Rig. If TR supports ECC LRDIMMs, maybe Z could get 8x16GB of those without a speed loss. Dunno what speeds they come in these days though.
I believe it's 2666mhz, but they'll cost arms and legs though :DQuote:

Ah. I was wondering how to get 4x32gb, and at 3200 or 3600. I can't find anything at the moment. Looks like there are several items I need to wait for. Maybe by Christmas!Quote:

Rig setup:

Dram: Flare X 3200mhz, Samsung b-die Timing 14-14-14-34 1.35v
Mobo: Asus B450 Prime-Plus
Settings:
CPU: 4.1ghz static/manual 1.25v vcore. All AMD auto overclock turned off. PBO/XFR etc etc (i couldn't keep up with all the things they're calling)
Dram: load XMP for first run / Ryzen Dram Calculator settings for 2nd run.
Software: Cinebench R20. Just to get an idea, not an extensive test like reviewers do.
XMP profile run: score = 7131
Ryzen Dram Calculator run: score = 7349
pretty good improvement with just sub timings tightened down.
Hopefully before xmas. They were announced a few weeks ago already :pQuote:

This does pose the question though...32GB modules do take a timing hit. I wonder if 8x16 with better timings vs. 4x32 would negate the 2 DPC penalty. I'm thinking it would.
Do whatever you want Z :D
@VO: Nice improvement there. And the best part is it was free!
Hah! 2 days later, and still "out of stock", the cost has gone up to $2.1k. And the 3960X has also increased from $1.4k to $1.5k.Quote:

I saw 3950X and 3960X briefly available at my local Microcenter. Haven't seen 3970X anywhere yet
snatched a 3970X today at my local Microcenter. The only one they had. If I was going to drive up there, it's gonna take an hour. So wifey was like "let me go". She got there less than 40 minutes.She literally beat the next guy by like 20 seconds or so lol.
Ahhhhhh I'm so jealous lolQuote:

They are selling out very quickly and supply is low. But at least they exist. On the other hand, Intel's 10000 series is true vaporware. Nothing exists at all and never did.Quote:

10980XE is no where to be found yet.
And now newegg has removed the 3970X completely. Not even listed as "out of stock" like before. Yikes.Quote:

Don't get me wrong, I am *really* cheering on AMD with this. I want AMD to stomp Intel HARD. I want BOINC dominance!! ;) Also, the only way to force real advancement.
I want one, and I will pay for one. But this is starting to move from frustrating to damaging, IMO.
And I don't believe any retailers promise about availability for now.
my local microcenter has 2x 3960X available as of the time of this post. I'm still aiming for another 3970X though. I have all the gear ready, just not the damn cpu.
Newegg finally added the 3970X back, but still not available. And with a second price increase, now $2,225.Quote:

Please don't overpay. MSRPs are $1400 and $2000 respectively
Okay, I finally have a 3970X on order and need to buy the rest of the parts now. It looks like the new G.Skill 32gb DIMMs are not yet available, right? So I guess I am going down the path of "better timing" 8x16gb. Could I please get a recommendation or two for which kit to buy?Quote:

It's my first, and I am not clear on the cooling requirements.Quote:

I assume the "360" comes from 3x120mm fans cheek-to-cheek, and that is kind of an industry standard for describing an AOI with that configuration. In this particular case, the radiator is longer than the fans. Fair enough.
But when the chassis manufacturer (using the chassis above as an example) says it will fit "Three 120mm or two 140mm fans and up to a 360mm radiator with a maximum thickness of 50mm without fans", do they mean it will really fit a 394mm radiator with 3x120mm fans?
I am totally confused, and I really do NOT want to have to trial-and-error vial mail order.
That case will support the X72. All radiators are physically larger than the size given, especially for AIOs since they have an additional area to hold a little extra fluid. If radiators were exactly the same size as the fans that could be mounted to them, there'd be no room for the tubing to connect.Quote:

For case: I went with this : https://www.amazon.com/gp/product/B0...0?ie=UTF8&th=1
My configuration for that case is using 5 intake fans ... 3 on the back side, 2 on the bottom. Radiator mount on top with fans configured to push the hot air out to the top. Works nicely so far and also kept my VRM and other stuff cool. I'm crunching WCG full load and cpu temp averaging around 73C at 4ghz.
Hi all,
Merry Christmas to all in first place.
Need some guidance on a machine with lots of cores and at least with 128GB of memory. At NFS@Home we have a bunch of outstanding work to be done and the backlog keeps increasing. Usually we submit the NFS@Home datasets to clusters but only Greg, the admin, manages this so we at mersenneforum will soon create a crowdfunding link so we can support him on this. I would say that for a 32 thread machine a post processing task can take between one to two months of CPU. It’s is better to buy a new domestic AMD machine or Intel one? Is it better to go for a server CPU or just pay for Amazon cloud CPU time? The client uses is MPI based and if we connect nodes these must be linked with infiniband since during the post processing operation between nodes lots of data must be transferred.
