K, this is the very stick I would have bought if I didn't get the RGBs.
So, we've ruled out RGB having less quality as a cause as you are having the issue w/ non RGB.

Update : x399 taichi w/ version 1.3 bios
RAM : 2 packs of : https://www.newegg.com/Product/Product.aspx?Item=N82E16820232491 2x (2x8GB)
- Confirmed stability of Mild OC 3.7Ghz @ 1.21V for :
- 3200Mhz@CL14 (cinebench runs 5x /passmark95 burnintest 1x /aidi64 stress test (15min) / Prime95 (benchmark test passed/stress test passed 1hour run)
and
- 3433@CL16 (16-16-16-36) (cinebench runs 5x /passmark95 burnintest 1x /aidi64 stress test (15min))/prime95 (benchmark test passed/2hour blend stress test ran (zero errors max temps on Noctua 71*C)
For Aidi64 stress test Temps on CPU maxed at 70*C with a room temp of 25.5*C
-----
- 3600@CL16 (16-16-16-36) TBD
- 3600@CL16 (16-18-18-38) TBD
- 3600@CL17/18 TBD

I also ran GPU stress test on Aidi64 simultaneously while stressing the CPU and everything else to make sure there was a decent amount of heat being dumped into the case. GPU sat at 100% throughout the test .. Quite Toasty to the touch even the backplate. Fans spun and ran at 900 RPM. I have an MSI GAMING X 1070 : https://www.newegg.com/Product/Product.aspx?Item=N82E16814127947
This is about to get comfy with a Radeon RX Vega 56 soon . I think i will add some bottom blowing fans once I do this. Cooler being used is :
http://noctua.at/es/nh-u14s-tr4-sp3

Lots of air floor feeding it and exhausting. Top fan above CPU area is a 140mm and there's quite a bit a heat coming off of it when the CPU is maxed. VRM hit a max of 51*C.

So, stable memory with mild oc of 3.7Gz @1.21V for 3200@CL14(14-14-14-34) / 3433@CL16(16-16-16-36). All timings are XMP profile settings. Nothing else modified besides CPU clock set to 3.7GHz, voltage set to 1.21V, and XMP profile 3200/3433 selected in bios. As for Prime95, i've decided to break my testing in it up into stepped sections where I push the CPU harder and harder... It really seems to wreck the CPU and want to do so slowly and in a scaled fashion. I'll be probing 3600 memory settings later on tonight and seeing where it breaks in testing and at what timing configuration. I think i'm going to have to break from 16-16-16-36 timings and introduce some 17/18s/38s.

Have thought about RMAing and just getting a quad channel kit (possible will fix issues) but am exhausted from this whole process and having a ryzen 1700 that I have to RMA and a return of this AIO cooler. Based on my findings, will decide what to do tomorrow.

I think, overall I'm happy that there's so much range for the CPU OC and for mem OC. I recall that Ryzen starts to top out at 3200. So, simply having the option of 3600 is awesome but I'm stable at 3433@CL16-16-16-36. I'm content w/ this and a 3.7OC across all cores @ 1.21 volts. I think I can drop the volts or up the clocks but I'm going to run this for a while before probing other settings. It's time for some real workloads now that she's proofed.

Question : Has anyone ever thought of or does anyone here put a fan on the backside of their mobo in the area where you have a mobo cutoff?


I noticed a bit of activity w.r.t to chips back there and I notice that the backplate gets quite toasty when you're pushing the system and figured it wouldn't hurt. I've also noted from reviewers with FLIR cameras that things can get kind of toasty back there. Thoughts?

I was planning on doing this myself. Specifically, after getting VRM waterblocks, I was going to either find pre-made ones or buy a copper sheet, drill holes where appropriate so I can use thermal pads with the backside components to the VRM, make sure for clearance, use electrical tape (I have both tape and liquid to spread in a sheet; meant to prevent electrical shorts by contacting traces and solder points on the back), but was considering just leaving a larger part of the plate to sink the back of the socket. My mount for the Core X9 cube has where the drive part is lower, allowing a wind sweep under. So I can attach heatsinks to the plate in the area of that recess and use the fans in the side of my case to blow air in to cool it in part, or so my thoughts go. But, since I'm at my desktop, screenshot time!

I've scored better on some of these since then, but...

@ajc9988 that 32M wPrime run seems longer than I would have expected. Since it runs really short on these processors did you try running with high performance? ie get that multi up to max before the start rather than stepping the multi up through the bench.

Besides benchmarking, this CPU is such a beast once you start throwing heavy workloads at it. Already have 2 VMs running with a few Visual Studio agents compiling code and it eats through anything you throw at it. Can still game while it's compiling code in the background with no FPS drops. Amazing.

I know. I have a lot more work to do on that score (I take it this is the same person I know from NBR and 0_o from HWBot). This is more me just messing around at the moment. I have A LOT more to do after I buy the custom loop later this month after I finish this project in about a week and a half. I didn't even start up in diagnostic mode for this, although I did set high performance in priority, IIRC. That is one of the scores that has been bugging me though, although the 1024m is looking nice. I also just moved to the fall creator's edition beta, which evidently just hates wPrime (lower scores on both). Also, realbench pops up saying that the build has the RTC bug, so I cannot submit the newer scores since I updated to that, as anything without HPET enabled would then violate the rules (I don't get the warning on the Spring Creator's edition, though, so they likely resolved it on that build). That's also why I didn't post the CB11.5 where it had 27.2, I believe. If that was caused by the RTC bug, no use in sharing. I got 22.2 on it on the Spring Creator's edition, though. But more will be coming once I have time to play!

Yep, same one.

It certainly seems to be living up to it's reputation of being a beast. Enjoy.

Very nice. We're looking into getting a new workstation at the office and I'm hoping we can pick up a Threadripper and get some good value. Cores are gold.

So I tried 4.2 but to no avail. Even 1.425v was crashing as soon as I ran cinebench. Wanted to get atleast one cinebench run in Will have to settle for 4.1.

Keep in mind that there have been problems with the RGB because of how it siphons power for the lights. I know early Ryzen 7 systems were exploding these chips left and right.

I thought that the problem was the beta nature of the software for controlling the RGB LEDs on them, and that it would screw up (especially if you were running other hardware monitoring software), and accidentally re-program and corrupt the SPD on the DIMMs, after which, the mobo didn't know what to do with them on next cold boot.

To the naive, it would look like the DIMMs were fried, but really, they just needed their SPD re-programmed.

You are probably right I just remembered that people were "killing" their chips a lot when I was building my R7 1700 system. Since I was going to spend that amount for shiny lights I didn't really track I much after that.

So whats the latest on the coolers? Any comprehensive reviews of the fully sized TR4 coolers vs. the compromised options @launch?

Phanteks have a waterblock for TR4
and will add support for TR4 to their dual-tower air cooler PH-TC14PE:

A nice gesture, but that's about it.
The contact surface on TC14PE is tiny, totally useless for Threadripper.

In my opinion this platform is still nothing but a vapor.
Outside the 20 something Asetek AIO variants and the Arctic & Noctua heatsinks (which you may or may not be able to find) and few waterblocks there are still NO coolers available.
Outside the waterblocks all of the available solutions are insufficient and inconvenient.

The coolers for a new platform should be available BEFORE the launch, not months AFTER it.

The vast majority of manufacturers haven't even annouced coolers or mounting kits for Threadripper (or EPYC), so there is no relief to be expected any time soon.
Enermax AIOs got pushed back by nearly two months as well

@The Stilt, TC14PE's base is not full cover indeed, but it seems to me it provides a bit more coverage than Asetek's base. (I might be mistaken though.) Furthermore, I read in an older review that its base is planar, not convex like some (or all?) of the Asetek based AIOs.

TC14PE base is 42.5x45mm, which is even smaller than the Asetek AIO's (52x52mm).

Thanks. Which is the longer of the two dimensions, in parallel with or perpendicular to the heat pipes? In parallel would be bad, because then the overhang of the dies would be even worse.

You have :
  • Custom water cooling contact blocks (full coverage) coming out from various companies
  • General compatibility AIOs that have insufficient surface coverage.
  • A new breed of AIOs w/ full coverage plates like :http://www.enermax.co.uk/cpu-coolers/liqtech-tr4/
and you have (Air cooling) :
http://noctua.at/en/noctua-presents-cpu-coolers-for-amd-s-ryzen-threadripper-x399-and-epyc-platforms
http://noctua.at/en/nh-u14s-tr4-sp3
https://www.amazon.com/Noctua-NH-U14S-TR4-SP3-premium-grade-cooler/dp/B074DX2SX7

For some reason, the nh-u14s-tr4-sp3 was in stock at newegg (I ordered it) and have it installed now its not even listed. I provided an amazon link instead. The Enermax Liqtech TR4 240/360 were also listed on newegg now they've been yanked. Not sure what Newegg is pulling or what's going on. Don't buy the 12s/9s Noctuas.. They don't cool as much as the 14s.

As for the nh-u14s-tr4-sp3, I had an artic freezer 240 installed prior and the nh-u14s-tr4-sp3 cools my CPU 5-8*C better. No risk of water leaks plus VRM temps are down 3-4*C as well. You can't beat that for $80. Warning : this sucker is huge. I can maybe fit a business card in between it and the backplate of my GPU in slot 1 and the x399 taichi has the best spacing between the socket and the PCI-E slot. That being said, you can adjust it to slide over, I just didn't want to. Noctua says this results in a 0.5*C temp increase.

So, for the value and if you don't want to worry about water pumps/leaks, go w/ the noctua 14s. With a mild OC 3.7GHz/1.21v, max the temps the CPU gets over 2 hours in prime95 is 71*C. Otherwise, it's idle at 30*C for me and pops to 48/55*C under a full load w/o heavy Floatingpoint/math Ops.

Yeah that contact plate size looks like a joke... Noctua did this better.

Nice. Didn't know phanteks came out with a TR block. XSPC just released theirs and swiftech started taking pre-orders for their apogee TR waterblock. Heatkiller should be next as well.
Their water block looks like it has the best fin surface I've seen. It really looks like a beast :

Looks like the fin surface area is nearly double what i've seen even on the EK block. It looks like the EK block simply modified the base plate w/o modifying the fins. The Phantek looks like the best waterblock i've seen so far. Question i have for this waterblock is the flow pattern.. So, it flows from L->R or R->L, wouldn't one die get hotter water above it than the other? not that it will impact things much but still. Very impressed with the phantek block. This is the tiny EK block fin surface area for comparison :


Although the water in/out is in the center, you'd still have an up->down or down->up flow having hot water from one die flow over the other and then out.
