Then you will have to wait at least until end of May or June. AMD says there will be a major AGESA microcode update in May to bring the memory XMP profiles up to equality with Intel platforms.

. . That suits me, I was thinking about June as a good time to make the jump.

You might see a B stepping in your July/August timeframe. I have my doubts that you would see a 1.X or 2.0 motherboard revision in that same timeframe. I would suspect September or likely December before you see new motherboard revisions. At least for the big Three. You might have the second tier players on a faster track to get exposure and market leverage. The aftermarket cooler manufacturers should have their $*it together by May.

It's starting to look like my decision to just hold out until ~Black Friday is becoming a great plan. I was thinking of waiting until about August or so, and then decided "if I'm waiting for August, then I might as well just see what kind of BF deals end up happening, at least on DDR4--that stuff is expensive."

I was thinking of waiting until about August or so, and then decided "if I'm waiting for August, then I might as well just see what kind of BF deals end up happening, at least on DDR4--that stuff is expensive."

I think there is definitely some price gouging going on with regard to Ryzen compatible DDR4 memory currently. Because the platform is currently so finicky, desirable DDR4 memory has increased in price by 50% or so. I see lots of the most wanted stuff gobbled up by individual or small vendors because they know they have a market that is willing to pay exorbitantly. I myself went through 3 sets of different memory to get something that "mostly" works. This was a rushed product launch and we early adopters are the alpha testers.

Probably smart to wait for some Black Friday "bundle" deals to get into the new architecture. There is a benefit right now though if you are willing to put up with the problems. I have increased my SETI RAC by 1K just from the influence of the CPU alone in the one week I have had the system built and online crunching. I do CPU tasks twice as fast now compared to my previous FX processor.

Guess what !
Under the same conditions (100% SETI or PRIME95) my Ryzen 1700 temperature went down from 62 to 52 !!!!!!
Do you want to know my trick ? Don't forget to swith the CPU fan mode from ''SILENT'' to ''MAXIMUM'' !!!
It all went back to default after the BIOS update....

I might have a look at overclocking today just for fun. I am sure I can bring it to 3.5 stable on air in no time.

Is that with the latest 0515 BIOS for the Prime? That was one of the changelog notes about the latest BIOS. Reworked temperature reporting. They took away the +20° C offset for the X processors, JUST for the temperature reported by the motherboard monitoring chip. (ITE8665). The EC chip still reports the offset as well as separate Tctl and Tdie temperatures. But the major effect is that fan profiles are feedback sourced from the motherboard (ITE) monitoring chip, so that caused existing fan profiles to be way off. I had to go to custom profiles to get my fan speed rpm's back up to cool the chip properly under load. My previous default Turbo fan speeds are now very inadequate. Overall a smart decision on the motherboard manufacturers because it allows better temperature control by a wider variety of cooling solutions.

Would an H60 provides better cooling than the stock wraith cooler ?
It would fit very nicely in my smaller new build.
I would let the H100i v2 on the big box for the FX-8350 as it is right now.

I'm pretty sure the H60 would cool better than the stock wraith cooler. Maybe by not much though. The wraith cooler isn't a bargain basement design, its pretty good in fact.

Looked back through the thread and see you have the Asrock X370 Killer motherboard with the 1700 CPU. Based on forum comments on the 1700, you should be able to overclock at least to 3.8 Ghz on air. So, yes ..... a lot more than 3.5 Ghz. Try to get your memory running as fast as possible too. The Ryzen chips respond more to memory speed and thus the Data Fabric speed than to simple CPU clock speeds.

Yes the stock cooler is good and I did went to 3.5 (I will wait for 3.8) but I got nervous at 68 deg. and stopped Prime95...
And yes I should work on memory speed issue. But I am not sure where to start. I have never change memory settings in the Bios before.
I guess I will have to take some times reading the basics of memory settings and play with them. A lot of crash and reboot ahead !!!
RAM here Corsair Vengeance LED 16GB (2 X 8) DDR4 2666MHz C16 1.2V Choose them for esthetic reasons... ASRock released a BETA BIOS update that ''Add DRAM Timing in OC Tweaker.'' Should I go ahead and do the update ? Otherwise the machine runs so well... Cheers !

What is the exact Corsair part number for the modules? And how many? What is the memory clock speed running them at? I assume since you said you have not overclocked, they are running at stock JEDEC 2133 Mhz. I would at least try to run them at their designed XMP profile of 2666 Mhz. I don't know what the BIOS in your Asrock looks like but I would bet it is pretty similar to my ASUS since the companies are related. If you have an AI Tweaker or similar setting in the BIOS, look there first for some menu item that is called D.O.C.P. Standard. Click that and it should open up a drop down list of memory timings. Find the one for 2666 Mhz and select it. F10 save the settings and reboot to get back into the BIOS to see if it took. The reboot might cause the machine to start up several times in a row as the IMC in the Ryzen goes through memory training. That is normal. As I said, Ryzen really responds the best to the highest memory clocks since that is tied to the Data Fabric in the SoC. You will see the most improvement there in performance over a simple overclock of the main CPU clock. I would probably go ahead and update to the latest BIOS. Make sure you do it from within the BIOS itself from the Tools menu and not attempt the update with any online update or within Windows. Have the BIOS file on a local hard drive or memory stick.

Let us know how you do.

The problem seems to be I should have let it reboot again and again. I did select 2666 in the menu but after 3 reboot I thought there was a problem and brought it back to 2133. I will try it again now and see what happen.

It finally boot after 4 attempts but it came back to 2133 :(
I will update the bios and see if it helps.

Yes, try to update the BIOS since you said that was one of the things they improved. You might have to bump up the VDD SoC voltage a little too. Either put in a manual voltage or add in an offset voltage. I would guess that your stock VDD SoC voltage is somewhere around 0.881V or so. Try to add in 0.01625V for an offset or put the voltage to 0.950V in manual and try your memory overclock again to 2666 Mhz. The SoC voltage helps the IMC in the chip handle the higher memory clocks. Also, until we get the promised AGESA memory timing updates in May by AMD, the memory timings are very limited. Your best chance at achieving any kind of memory overclock over stock 2133 Mhz is with single sided memory, 2 X 8GB sticks and preferably made with Samsung B-dies at CAS latency of CL14. That is the most compatible at this time.

According to Tech Powerup the effect of faster memory on Ryzen is minimal at this time. There is some benefit for memory intensive tasks, but the extra cost of the memory is often way more than the boost in performance.

Well... It is still stuck at 2133 after Bios update and many try and error voltage settings and reboots, I give up for now.
The machine runs very well with all settings to default (only fans speed settings) it is 3 times faster than the 8350, it is stable, it runs cool and power consumption is very low. I am now running 19 Milkyway@home tasks (6GPU+13CPU) with only 310 Watts (Total system power in) and cpu temp stays at 48 on stock cooler. Since all works VERY WELL I will just wait for a while and see.

Interesting article. Thanks for the link. I don't agree with all the conclusions though. A read of the comments points out quite a few flaws in the tests. I don't think a gamer would agree that a 10 FPS increase in a game solely because of the memory clock is negligible. Apparently minimum frame rate in a game is the most important point whether a game is considered playable. And that is something that correlates directly with memory speed. And if you consider that the platform is designed for long term longevity, it could be considered short-sighted to limit oneself to the current memory speeds at the lowest purchase price. We all know that the memory environment is going to change in May with the AGESA updates. Maybe the article should have been held off till the platform is more mature. The buyers of this new architecture are enthusiast level and the price of memory is not of much concern. Most have constructed their systems simply to learn how far they can push the performance and the price of memory is not of much concern. I see a lot of effort being put into the aesthetics of their builds sometimes being primary importance to performance.

I agree with the observation that currently memory is a sellers market. At whatever price point consumers can be gouged for. But I just paid about $50 more for my latest 16 GB of memory over what I was using before. That $50 I consider well spent because of absolutely no aggravation involved with getting it to run at my desired clock. I just installed it, selected 3200 Mhz and !voila!, it was running at 3200 Mhz. No muss, no fuss. No endless reboots and stress tests to see if my latest configuration is stable. I have been fighting the previous memory now for about 2 weeks just to get it stable at 2933 Mhz. If I consider the number of hours spent at my usual labor rate of $20/hr, it was absolutely well spent. And the memory is future proofed if everything falls into place in May as expected. The compatibility may improve greatly in May, I don't have a crystal ball, I don't know. Cheap memory may become just as easy to get to rated spec as the high-end stuff you need right now. My 3600 Mhz memory was not purchased just to ostensibly get 3600 Mhz on the system, it was to insure that I got the most compatible memory dies for the platform as it now stands. I could have waited till May of course and lived with what I had previously. That memory will sit on the shelf waiting for my next system build. There is no point in having DDR3 memory now that DDR4 has no price disadvantage. It is cheaper in fact. Any new builds will be with DDR4 memory. By the time I get around to building my next system I am sure I will be able to use the memory I could only get to run at 2933 now running at its spec of 3200 after May. Anyway .... my $0.02.

I don't think a gamer would agree that a 10 FPS increase in a game solely because of the memory clock is negligible.

A lot of gamers tend not to be very rational.
Getting excited over 10 fps when you're talking about going from 40 to 50 is a big deal. When you're talking about going from 240 to 250 it's nothing.
Best to express things as a percentage. A 5% change is nothing, and in some cases well within the errors of measurement. Getting a25% boost is significant, even if the error margin is as high as 10%.

What people have to decide is what value they place on how much of a performance boost they will get.
For games, the memory speed is insignificant. For crunching, as their results showed, there are significant (although small) gains to be had.
So people need to decide if an extra 40% on the cost of their memory is worth it for an extra 15% boost in crunching output (or whatever the actual values might be).

Both arguments are good. Its all about what you want from your system. Here power consumption is priority and since I already have 3 times the crunching power I realy need due to power consumption limitations, the challenge is getting the most out of any watts so I can crunch more often. It would be totaly stupid in these conditions to increase output by 10% if it increases power consumption by 20%. But if my motherbord manufacturer tells me buy this particular RAM it cost 50$ more but it will works at full speed right away and it wont affect your electricity bill, I would buy it. The problem is the $50 is not in the same pocket... Hardware is my pocket and bills are my wife ;-) She would go nuts knowing that my computers draw more power then the rest of the house on a daily basis. I need to adress that, But maybe she is right...

Sorry to hear you are stuck at 2133. But I had my suspicion that would be your case. At least you tried. Corsair memory is cheaply constructed with general purpose dies, usually SK Hynix or Micron. And a lot of their memory sticks are dual rank. A big no-no currently. About the only thing I found positive with my Corsair 3200 LPX is that they fit under the Noctua cooler without having to move the outside fan so high up on the fins that I couldn't put the side cover on my case with my previous memory.

I just moved everything into a new case and finally received my Corsair AM4 bracket so I could reinstall my Corsair AIO cooler. I could then put in the G. Skill memory with their large heat spreaders with no interference issues with the Noctua I had before. I am a little surprised though in how much better the AIO is cooling the chip. I always thought from all the reviews that the Noctua NH -D14/15 were no slouches in cooling compared to the typical 240mm AIO. I am beating my previous high temps by 5-10° C with the Corsair H100iV2 AIO compared to the NH-D15 I had on the chip while waiting for the bracket.

I knew those sticks where not the best around and now I want to replace them with good quality RAM.

My motherboard support the following ;

- Dual Channel DDR4 Memory Technology
- 4 x DDR4 DIMM Slots
- AMD Ryzen series CPUs support DDR4 2933+(OC)/2667/2400/2133 ECC & non-ECC, un-buffered memory.

What should I look for if I want 16Gb of higher than 2133MHz RAM speed ?

Would a single rank double sided multi un-buffered DDR PC3100 triple channel and single powered 1.2 to 1.5V quadriple
serial CL-36-24-36 stick work at 3200MHz on my USB3 SATA DIMM port ?

I guess I will go to local store today to get some advises...
