More interested in how Zeppelin manages to be form a 4-chip MCM. They have a giant PCIe/SerDes PHY block, but I can't say for sure how many 16-lane links there would be. Link speed is unknown too (8 GT/s? 10 GT/s?). Ideally, one needs five 16-lane links to achieve glueless MCM plus 128 lane PCIe.

打算落搭 1700X
iMac 十世都唔出


過兩日落場睇吓有乜板同有冇貨先
唔記得之前 sandro 推果隻 modular 牛牛乜型號添

Why not 1700?
All those three are 99% same, except the X series has so called XFR.
If you overclock them, the highest clock are all within 100 MHz.

Had a game bound by single thread, and not interested in OC either. Thought OCing would disable many of the power mgmt features, wouldn't it?


Edit: It seems the idle states are still there. Hmm.
Edit 2: Eyeing for the MSI B350 boards.

This is even less than when I overclock my 6700k to 4.4GHz....... It's no big deal, if your cooler is better; the money you can save from 1700X is worth a very good water cooler.

And we are taking a ...

Hmm, interesting. That said at this price point KBL does seem very attractive out of the box, esp 7700K doesn't seem too far behind 8-core Ryzen in Linux compilation benchmarks, while I am not really into the places where Ryzen shines (media editing).

Decisions, decisions, decisions.


P.S. Moreover, dom seems getting 1700 soon.

seems like P1/P2 is still available in OC mode, hmm.

If you were referring to me, I always suggest Corsair RMx series (make sure you don't buy the old RM series).
I think they have the best performance given the price (not efficiency wise, but ripple p ...

Yep, sorry for misremembering your username.
Leaning towards OC 1700 with B350, perhaps 3.7-3.8 GHz all cores. Just that the idea of burning more power when browsing web pages kinda bugs me. Not sure if idle downclocking still works in OC mode.

A quick search gave me this:

On overclocking, the idle power does go up a bit, but it is just on par with 7700k's idle......far  ...

Probably not 4Ghz, since I heard hitting 3.9+ GHz needs a high-end board. I'd like somewhere around 3.7 and tune the voltage for perf-watt.
Saw some nice results in power consumption.

Not knowing much about this, but there is a thread about the interconnect being the bottleneck for some cases:
https://www.reddit.com/r/Amd/com ... ving_like_a_dual_4c ...

It is not really a "design flaw" but apparently an intentional design choice (no system LLC). Yes, it is a bottleneck, but only for implementations that assume a giant shared LLC for all cores, and ping-pong the working set between cores on top of the assumption. Otherwise, it is no different from any UMA chips without a shared LLC running at core clock.

The OS needs to be NUMA-aware to fully support Ryzen

It needs to be aware of the cache topology, not NUMA.

Both

The chip is UMA, and doesn't statically partition the physical memory address space betweeb CCXs. So essentially apps just need to be aware of the topology, e.g. porting console CPU scheduling code to the PC. XB1 and PS4 have essentially the same situation.

NUMA awareness isn't a must. Let alone the fact that the chip is not advertising itself as two NUMA nodes, and thus NUMA aware apps relying on OS API would not treat it as two.

Things do seem kinda messy. The only thing which has correct readings is Ryzen Master. Even Windows reports a different operating frequency, and common tools like CoreTemp do not work at all. SpeedFan reports my fan spinning at 10630 RPM.



Burning 3.7 GHz @ 1.2V (stock: 1.1875V) with Prime95. The temp so far lies within 55-58C. I use Noctua NH-U12S, FYI.

Edit: 1.2V crashed after 5-10 minutes. Trying 1.225V now.


Edit: 3.7Ghz @1.215V is pretty stable. 3.8Ghz @1.25V seem to be stable, but somehow Firefox crashed.　3.9 GHz @1.275V crashed CB15 immediately. Gonna stick with 3.7.

Not really sure about the voltage, but from what I heard Ryzen tends to use a lot higher than the numbers you gave(PCPerspective applied 1.4V, and it went up to 7X degree C), however you may need a b ...

The F/vt curve is significantly steeper beyond ~3.7 GHz as experienced by many.

PCPer targeted 4.0 GHz for the 1700. 3.9-4.1 GHz requiring at least 1.35V is kinda expected (mentioned by AMD too), especially on 1700 which is presumably binned with parts performing worse at higher frequencies.

So far I didn't see any OC reviews on undervolting, except one who clocked 1700 at the same clock as mine (3.7). But I forgot which reviewer it is from, and the voltage. Sigh.
