If you can do a 1:1 replacement versus the EK TR4 block, I'd be curious to see how much improvement the change in water block alone gives to your temperatures. Because 2.2 lbs is pretty hefty for a water block.
Yeah, I was a little surprised at the orientation as well. They are still waiting to get a photographer to update their website. Really curious to see what kind of temp drops I see with this.
K, you have a solid understanding of this. Question : Every reviewer (when the CPU was at stock settings) noted poor performance in certain heightened RAM clocks when they started ratcheting up the RAM clock timings above 2133. This is likely due to the 180W ceiling the CPU imposes whereby at higher ram clocks, it uses more power and thus must cut power to cores and not clock them as high to stay within the stock 180W ceiling.
I think anandtech defined the phenomenon as operating exactly like this. Higher RAM clocks when the CPU is stock starves the cores for power. Thus, to keep things balanced, you essentially have to OC in order to get things back in balance. I stated prior w.r.t to boot loops and instability that my bios OC appeared not to be taking. I am not sure what allowed for it to take but it took after I did the 1.0 -> 1.3 update. When I didn't OC the CPU I got boot loops and 3600@CL16 XMP setting wouldn't take. After I applied a mild OC to the CPU 3700Mhz @1.21V the memory settings took, i booted to windows, ran cinebench, am now running burnintest and will switch to more extreme testing.
So, is the instability due to the CPU doing probing of the voltage range/clocks on Post and in windows with a 180W limit but being unable to supply sufficient settings to run the RAM at 3600Mhz while giving adequate power to the cores simultaneously? Trying to root cause why stock CPU + 3600RAM @CL16 is unstable.
1.Sync the H/W Monitor and Dr.Debug code Temp source to Tctl.
2.Update AmdPackageString to "ThreadRipperPI-SP3r2-1.0.0.4"
3.Enhance SATA type M.2 compatibility.
4.Include "BT On/Off" item for Bluetooth control.
Heads up, bios v2 is out for the x399 Taichi.
The Asrock Taichi seems to be the most stable, with the best ram support.so......... Now that TR has been out for awhile... what's the best MB to get??
Thinking about this one... Gigabyte X399 DESIGNARE EX
Anyone got on feedback with this board?
Got the 1950X, 360 enermax, Case and P/S. Just need RAM and MB now and a 1080 ti. I'm taking my time.
An inquiry for folks who have spent some time running their 1950X at stock speeds to satisfy my curiosity:
Background: When running the 1950X CPU at stock speeds but with RAM "overclocked" (e.g. running at 1.35V and DOCP speeds instead of "default" 1.2V JDEC speeds), there is a possibility of decreased performance. This is because the CPU needs to allocate more power (from its max TDP of 180W at stock) to the memory controller. Anandtech results suggested a possible 13W loss of power to the CPU cores under such a scenario. But they never actually tested the performance tradeoff of increased memory frequency versus more power available for to boost CPU core speeds. See: https://www.anandtech.com/show/11697/the-amd-ryzen-threadripper-1950x-and-1920x-review/19
Question: Has anyone here run benchmarks on a non-overclocked 1950X at different RAM speeds (e.g. 1.2V 2133 MHz vs 1.35V 3200 MHz) to see how big of a performance impact this has? And which is more advantageous (e.g. higher memory speeds/infinity fabric performance vs more watts available to CPU cores).
The Anandtech article talks about the possibility of decreased performance, but they don't actually test the impact. I presume that, unless your work load is mostly limited by memory speed/bandwidth, that overall system performance might take a hit when running RAM at faster speeds. Which would be the opposite of the desired outcome. But who knows? This infinity fabric business is new to me. You guys have done a lot of testing (in aggregate) so might be able to answer this question relatively easily.
[EDIT: By the way, I could not find the mentioned reviews that discussed this issue and showed considerably reduced performance at higher memory speeds. But maybe I didn't look hard enough. Most reviews showed higher performance at higher clocks, but it was not clear that they compared at 1.2V for stock memory speeds versus 1.35+V for higher memory speeds. If RAM voltage was kept relatively constant, that would reduce the power draw differences.]
I might be misinterpreting your post but you seem to be saying that you can’t find any evidence that proves this is an actual problem?
unfortunately most of the country or the world can go there...... The closest one for me is over 1000 miles away. Any those sale prices are always in-store only.FYI Threadripper is on sale @ microcenter..........$150-$300 off
I have the Asus Zenith Extreme. I would've bought the Taichi if I didn't see the Asus board at $350 (also considered the MSI board). I have the X370 Taichi. I like Asrock and Asus BIOS - not too familiar with Gigabyte.so......... Now that TR has been out for awhile... what's the best MB to get??

But thanks for the heads up for the small number that can make it there. (speaking world-wide)
Indeed. It's a curiosity question with regard to threadripper and the relationship between package power and power allocated to the CPU cores themselves when operating at the default TDP limits.
The Anandtech review appears to show a potential performance issue caused by running at higher RAM voltages when not overclocked. And the poster on this board (ub4ty) seems to suggest that performance regression at higher RAM voltages/speeds was commonly found in reviews when tasks were not heavily bound by memory bandwidth -- that was news to me! I could not find such reviews.
So, the question is really whether there is any real evidence for a performance tradeoff at stock CPU settings when using higher RAM frequencies.
[For Reference: I was more likely to see examples like this (see second graph), where virtually all tests show higher performance with higher memory speed.
https://www.pcper.com/reviews/Proce...0X-Review/Memory-Mode-UMANUMA-and-Memory-Spee
That said, it is possible that these reviewers are running their RAM modules at 1.35V (standard voltage for higher clocked kits) at both 2400 and 3200 MHz, meaning the disadvantage of higher voltages is uniform. They do not specify.]

Unfortunately, I got an email from Newegg yesterday saying they're charging state tax nowAnd interestingly it's worth doing the math on what you actually end up paying when considering taxes paid. In some cases you actually don't gain anything monetarily by going to a store versus buying from Newegg for example (although it's good to be able to physically go to a store (if it's nearby) to return an item or whatever if there's a problem).
From their website:Doesn't Newegg's tax charges depend on the state they're shipping to though?
I'll try to get it done tomorrow. And this is closer to 2.4lbs
In other news, my arms got tired playing a drum roll waiting for a report from:
