Who knows. It doesn't take that long to find stability, not now the bios is better anyway. Latency means little to ryzen right until you hit 3200 then it has a part to play.

Good to know, thanks :) I need 32gb though so I suspect that 3200mhz is out of my reach at this time... hence I'm keen for any news that might resolve this ^^; I'll just keep my eye out over the next couple of weeks.

Technically speaking for best stability you should wait till is end of life. Unless your in a hurry, wait a few more months, or even zen+.

I can wait until Covfefe Lake hits to see the benchmarks, but tbh I really need to pick something at that point. My favourite games are bottlenecking quite badly to the point where I've stopped playing them due to it not being fun any more; problem is that two are tied by single-thread performance, and the other yearns for more cores, so I don't have an obvious "right choice" CPU at this time :( Flip side, I also work on this PC, sometimes with 100-200mb graphics files, and it absolutely must NOT crash during the long save process. The software is solid, but I can't risk a platform that isn't 100% stable.

It is 100% stable if its overclocked correctly. A lot of people are trying to push it outside of its limits the new bios has sorted a lot of issues out.

People have said it is stable when not overclocked. so the question is do you need to overclock right away? Buy ryzen now, and then overclock 3 - 5 months down the line.
Just wondering how come your not going for HEDT if you use it for work?

Eventually :) My concern is that there might be a significant downtime involved in finding the perfect overclock, which I don't really want to go through. On the other hand, Ryzen at anything under 4ghz is barely worth it for my single-threaded things :/ A 1600x may actually be my best option right now, since it has a nice high boost clock. How does it handle fast memory at stock speeds?

I'm not going to pay for a full on professional grade system because I only do bits of freelance on it at home - my day job is elsewhere and comes with its own hardware :)

Tbh I'm thinking that a 1600x is my best bet, since it has a nice high boost clock for the single threaded stuff, and the MT stuff will eat the extra cores at lower clocks and still be happy... Probably hold me until Ryzen+ :)

3200-3466MHz is the sweet spot. Latency means a lot to Ryzen at this point, so it's worth hitting the breaks on speed and getting the timings down.

It's a slightly different ballgame if you play with high bclk/refclk as this puts less requirement on the memclk so you should be able to reach higher frequencies this way.

From 'The Stilt' over at OCN.

This is an example why it's important to pushing timings on Ryzen when you get past 3200 mark.

So you have to spend a stupid amount of money on ram to get the best out of Ryzen. :/

I've got a 1600x just sitting in it's box because there are no decent motherboards (ITX) yet.

Not really? The G.Skill 3200C14/TeamGroup 3200C14 stuff is well priced imo. RAM prices are on the increase!

Ties in with mindblanktech videos on YouTube. In some of his tests the 3200 cl14 was beating 3600cl16

This is what I've found also. I can run 3600MHz CL16 with higher CPU, SOC and silly DRAM voltage, not tuned very well either. Not worth it at this stage.
3366/3466MHz with tuned timings is where i settled.

The next stepping will be interesting, future steppings of processors usually improve efficiency a little.

OcUK have G.Skill incoming soon. 3200 CL14 is at £200.

Any idea which kit it is? Been keeping an eye on the Trident RGB set but was considering going non-RGB seeing as there's apparently bugs changing the LED colours on the RAM.

EDIT: Nevermind saw your thread in the Memory section with the link to the OcUK page :p.

The TeamGroup x 8Pack stuff is 3200C14 too. Little bit cheaper.
 
RAM prices are definitely one of the biggest reasons that I'm waiting for Zen 2 (or whatever Intel brings out next year). I grabbed 16 GB of DDR3 for my current system because it was £57. I am not spending near £200 for the same (albeit DDR4) stuff over a year on!

Thanks for that, looks good so added that to my list.

No mention if the new stepping will included improvements to the memory controller but considering I'm waiting for Vega anyway I might as well wait to see if AMD releases the improved Ryzen. If I remember it was only around 3 months AMD released the C3 stepping of the PII 965 after the C2 version.
