Thanks for the info! I will hold off ordering the memory until the CPU actually ships, in hope of the 32gb version of the DIMMs becoming available. Does anyone have any insight to when that will be? The announce said Q4 2019, so I guess they have a few more days before they are officially late.Quote:

Thanks JPM. The 32gb dimms for sale following the link are all 2666. Are you suggesting I use those, rather than 8x16 at 3200?
I see the 3200 is sold out. I'd definitely hold out for that. They're supposed to be releasing 3600 too. Haven't seen a date yet thoughQuote:

According to the update you provided, it says "Q1 2020". And that usually means "by the end of", so March 31, 2020. I can't wait that long.
I guess I will go with 4x16 for now, and hope no high-memory projects need crunching for a while (or run with HT off).
Thanks for all the help!
Not to stress anyone out, but TR3 3990X 64c/128t Feb. 7th. $3990

Wow! I find it very surprising that there is no premium compared to 2x of the 3970X. Nice!Quote:

Samsung just showed off a 6.5GB/s m.2 SSD today. 980 Pro. Not available yet
any good cooler / aio you think might be able to cool the 3990X? I really don't want to go to the custom loop route
EVGA CLC 360. In fact EVGAs CLC series coolers outperform pretty much every other cooler on any system, regardless of CPU. Also the Thermaltake Water 3.0 Riing is realy good. There might be others but don't know off the top of my head. Pretty certain about EVGA being the best though.Quote:

Not sure where the chips are underneath the lid, so I am not quite sure if that is a problem or not. Under full load, temps are hovering around 67c. That is using the 3-fan Kraken X72, and not OC. Is that temp normal? I wonder if something that covers the whole CPU lid would be better, something like this?:

That's what I'm using on my 2990WX machines. I ordered the optional 2nd fan for it also. Don't know how it would do with the new ones.
The noctua won't be able to hold the 3970X, at least with my case. Mine was in the mid 80s when crunching MCM on WCG. Mumak, the author of HWinfo64, also used the Noctua and his was also in the low 80s. So i'm pretty sure the Air cooler won't be able to keep up with these new TRs. Your temp is actually better than mine, Z. I'm using deepcool castle 360ex and my temp was at low 70s while crunching MCM. I haven't dare to crunch Asteroids yet :)Quote:

Considering the 3990X can draw 280W when pushed hard at stock, i'm not sure there's any air cooler in existence that can handle that. In fact, Intel and AMD both strongly recommend water for anything 250W and above. That is in their own documentation. Unfortunately the 3980X and 3990X seem to still be under NDA so we can't see what coolers the reviewers used. Please don't even attempt a Noctua contraption on these Threadrippers lol
The Enermax Liqtech TR4 II has a full coverage cold plate, but all Enermax coolers have been failing at ridiculously high rates over the past year. I'd avoid them until they get their shit together.
Water Cooling is DEAD. Meet the THERMOSIPHON!

Yeah there's that. But the retail version is about 1/3 the size and can't handle the TDP of a 3990X, or even a 3970X with a mild OC. I'll be getting a couple of those for regular desktop CPUs though :D
In case you're wondering if you're missing anything from Intel, this should put your mind at ease...

3970X at a slight discount for the next few hours. $50 under MSRP with promo code EMCDGGH32 https://www.newegg.com/p/N82E16819113618
Wait for their 3rd release. It will use copper instead of aluminum.Quote:

SaM (stoneageman) got his a few days ago. Not sure how he got it that early though. Maybe they released it early in UK?
Looking good so far. I can't get mine till Friday. Looks like it's gonna produce about 124k boinc points/day (868k WCG points). Temps and power draws also looking good.
~450 watts running MCM and cpu temps were around 66C. He was using the Cooler Master ML360 RGB TR4 AIO with an ambient of 25C. But the CPU clock only ran at 3ghz (he had it on auto)
From the screenshots, looks like the 3990X finish a MCM WU in 3.5 hours with all 128 threads running. My 3970X ran 2.5 hours/wu at 4ghz and draws almost the same wattages. (420)
Z, you're gonna get one?
The 3990X? Naw. I think I am good with CPU power for now. Also, the 3990X has that NUMA problem with windows.
Newegg finally has some limited stock of the 3990X, $3,989.99.
Ah, I forgot the other reason: max memory. IMO, 2gb per thread is a minimum for BOINC, so 256gb. The 3990X supports only eight unbuffered DIMMs. No registered or LR DIMMs. And the largest available currently are (slow) 32gb. That means 128gb of fast, or 256gb slow. And that is with 2 DIMMs per channel, which is not the best. I think the fast 32gb versions are due by Q2? We'll see. 4x64gb fast DIMMs would be best. Any ETA on those?Quote:

Newegg has some 32GB modules now too

finally got it up and running Universe https://universeathome.pl/universe/s...?hostid=545169
Still have problem with bios, asus rog strix trx40-e gaming, DRAM can only run at 2133mhz. My kit is rated 3600mhz
For some stupid reason, Asus decided to pumped out a bios and lock DRAM speed at stock. They don't say it in the download page ... but if dig in more to CPU compatible list then there's a little note saying "Memory runs at stock settings" wtf?
Well THAT's annoying.
That is why i quit buying Asus after my Xeon v4 board. They just....i dunno. But i had enough.
I may have to put them on my blacklist as well. I'm already done with MSI ... what's up with these manufactures lies and dirty tricks sheit? I feel like they intentionally crippled the earlier boards so we'll have to go out and buy the new Zenith .. f*ck'em.
Is that a different board you used for your 3970X build? If so, why did you change?Quote:

Now i'm actually scare to update it. The Strix was fine with the same bios as the Prime, memory was running at 3600mhz. But it couldn't boot into either windows or linux (with mce=off). So I decided to update the bios and the rest is history.
1) Regarding windows and 128 threads:
https://www.anandtech.com/show/15483...3990x-review/3
Looks like SMT/HT + 128 threads + AVX2 + windows is a problem. See the NAMD graph and comments. And the the summary:
Does Linux have this problem?Quote:
What’s The Verdict?
From our multithreaded test data, there can only be two conclusions. One is to disable SMT, as it seems to get performance uplifts in most benchmarks, given that most benchmarks don’t understand what processor groups are. However, if you absolutely have to have SMT enabled, then don’t use normal Windows 10 Pro: use Pro for Workstations (or Enterprise) instead. At the end of the day, this is the catch in using hardware that's skirting the line of being enterprise-grade: it also skirts the line with triggering enterprise software licensing. Thankfully, workstation software that is outright licensed per core is still almost non-existent, unlike the server realm.
Ultimately this puts us in a bit of a quandary for our CPU-to-CPU comparisons on the following pages. Normally we run our CPUs on W10 Pro with SMT enabled, but it’s clear from these benchmarks that in every multithreaded scenario, we won’t get the best result. We may have to look at how we test processors >16 cores in the future, and run them on Windows 10 Enterprise. Over the following pages, we’ll include W10 Pro and W10 Enterprise data for completeness.
2) I beginning to think that Windows is too dumb to understand the chiplet architecture used in Zen2. For example, there are 4 chiplets of 8 cores each on a 3970X. Each chiplet contains its own cache. Scenario: (SMT/HT off) running 4 MT tasks, each task using 8 cores, it would be best if each task was contained in a single chiplet. That way cache calls would be fastest. Otherwise the task has to go out to the bus to retrieve the data elsewhere. But the poor task times I am seeing are making me think windows is not doing the smart thing.
Is there a way to make windows keep MT tasks tied to a single chiplet?
Is linux any better at this?
3) https://www.reddit.com/r/linuxmaster..._scheduler_vs/
I am going to have to try linux to see the difference. No VM this time, a separate boot device.
Seems if you limit MT tasks to 16 threads (8 with SMT off) it should keep them on each of the CCXs. Another possibility of poor times is using too many threads at once. Some threads finish first and sit idle waiting on other threads.
@Z: Supposedly Windows 10 Pro fixed the issue. Make sure you get build 18362.592 or later and it *should* be fine. Pro for Workstations/Enterprise isn't required.
Just so I am clear, are you talking about the issue that anandtech talked about, or the problem that I think is happening with keeping MT tasks with 16 threads (8 with SMT off) or less tied to a CCX?Quote:
