I think Ram vendors now love AMD for this, thats a huge boost, granted he achieved that through BLK overclocks but still, this is quite a strong showing, GTA 5 performance deficit is crushed.
Hopefully we see the platform stabilise more, this year is a good year for tech.
Yep its looking decent for ram. I just ordered this stuff:
https://www.newegg.com/Product/Produ...82E16820232443
With 10% promo code it was 188 bucks, really not that bad considering its 4000 speed. I looked at pricing history on pcpartpicker, and 4000+ stuff has always been this expensive so im pretty happy
Fascinate do you think that ram you just purchased will perform better than the ram you recommended to me earlier? https://www.newegg.com/Product/Produ...82E16820232410
edit: The reason I ask is because I keep hearing people saying ryzen loves the 14 timing ram.
That ram is great, the only reason i went to 4000 is that it wasnt much more expensive and the off chance ryzen ever supports 4000 in the future.
When i get my ram i am going to be copying those timings for mine, 14 14 14 34 3200 and hoping it works lol. Speeds over 3200 arent supported at all right now, and only down the road will we know if amd will ever support it. I just spent a bit more in case type of thing.
Edit: That ram you linked has the best chance of hitting rated speeds from what ive read, just be aware its still way early so you might have to settle at 2933 or 2666 til new bios come out. Hit and miss kind of thing.

Well the ram i ordered is 4000mhz, i wont be able to try xmp im gonna have to manually enter everything. I just figured 3200 14 14 14 34 was a good starting off point as its all the same samsung ram, assuming mine a little better since its being sold as 4000.
Im pretty new when it comes to memory, any advice is welcome
Some interesting RAM benchmarks to be found here http://www.legitreviews.com/amd-ryze...ormance_192960
So the deal with RAM is that what you want is Samsung B-die. Most RAM manufactures buys memory modules from whatever is cheapest. Most high speed Corsair memory sticks is Hynix or Samsung ICs
You can check any corsair memory if it's correct by the sticker In bottom left it says Ver 4.23. What you need is Ver 4.31 that is the fastest memory.
To run 3200mhz you need 2x8GB sticks. if you need more ram your out of luck and need to run slower clocks.
I was looking at this https://www.newegg.com/Product/Produ...82E16820233859
However read that they mix ICs between B-die and Hynix. So if you order one be prepared to send it back if the wrong version or go to a store and check for yourself(In my store all they had was 5.39 which is Hynix). If you want to be sure you are getting good memory and ready to pay a premium for it you want G.skill Trident Z memory https://www.newegg.com/Product/Produ...82E16820232483 is what I ordered (You don't need RBG but in my country RBG is all the sold).
It's 100% Samsung B-die so guaranteed to run 3200mhz in any of the top motherboards and is listed in most RAM compatibly lists. But is quite a bit pricier but if you want good RAM this is what you need. You can pretty much pick whatever speed over 3200mhz you want, the listed speed is just what they managed to overclock it too. A 3600mhz kit may be overclock-able to 4000mhz if you are lucky.
It does matter. "19" in this case means it waits 19 positive clock cycles before doing whatever is rated as "19" again, at 2000MHz that would be 19*(1/f) = ~9.5ns.
For comparison a CAS 14 2666 RAM would need to wait ~10.05ns which is still more time even if the timings are tighter.
That has absolutely nothing to do with the problem though, the timings that are problematic at the moment are internal timings. Those are fixed in AM4 currently and the controller is simply using the same values for everything you can throw at it. It is fine for most cases, they probably did this because the x16 multiplier wasn't that stable yet which is understandable.
The trick is using the 2666 profile (a lower multiplier), with tighter internal timings and then increasing the bclk to overclock the final frequency.
And the infinity fabric doesn't run at "half the memory speed", it runs at the same clock as the RAM. "4000 ram" runs at a clock of 2000MHz, it's named "double data rate" for this reason.
With all that rambling you missed the point that memory speed is more important than latency with ryzen. When i said it runs at half the speed of memory you knew what i meant...
Also timings is not why some boards are having problems with some ram, it has to do entirely with manufacturer. I have tried literally every combination of cas at every speed from 2666 to 3200 and nothing boots, this is because i bought hynix ram. CAS 15 2400 is max my ram will do currently, i can set 24 cas at 2666 and it still wont boot. This will be fixed when i get my 4000 kit, as its samsung b die stuff.
Also you do realize you shouldnt be using bclk to get ram up right? That is super janky stuff and messes with nearly everything in your system like PCI-E bus and could cause errors and instability. Not to mention the fact only like 3 AM4 boards even support that.
This is all very helpful. I have a couple questions about RAM if anyone cares to answer.
I was thinking of getting this 32GB kit. https://www.newegg.com/Product/Produ...82E16820232376
I know that using 4 sticks of RAM, I would have to run them at a lower speed than if I had 2 sticks. Is it also true that I could run this kit with 2x8GB sticks faster than I can run it with 2x16GB sticks?
Out of these 3 kits mentioned recently in this tread, which would be the best?

I would steer clear of 4 dimm kits entirely, you want single rank samsung b-die kits like the one i linked you other day :P
Those you linked are all samsung b-die, should all work at 3200. I only went with 4000 in case it gets supported down the road, which isnt a guarantee at all. After promo code it was around 30 dollars more than a 3200 cas 14 kit so i said screw it lol.
Read the post again, the math is there for a reason. Or even better, watch this and this. The x16 multiplier performs better than anything else that is supported even if it isn't as mature, that is obvious. But using the 2666 profile and increasing the clock will make it perform better than the x16 multiplier, which is the point. In that example with random values it would bring down the waiting time to 7ns which is only ~73% as long.
Nobody said anyone should. It is, however, still the way to get the most performance out of it. But you'll indeed fuck PCI-E lanes, VGAs will work at 2.0 and NVMe drive corruption is to be expected. That's for world record breaking on LN2.
Someone on reddit mentioned seeing up to a 20% boost in WOW FPS when moving to 3200 memory.

I want to make clear to people that WoW performance on ryzen is.....less than desirable.
I am logging in right now starting the broken shores quests, and it is almost always under 60 FPS. I dont think i would have been under 60 on my old pc with a 2500k.
I still have my old rig, will do testing later.
- - - Updated - - -
Welp got some bad news. My 6 year old PC is getting consistently higher FPS than my new one.
Standing in the exact same spot (deliverance point in broken isles) my old PC is getting 62-67 FPS and my new one is at 50-54. Its mind boggling to me as well. My new ram comes tomorrow and i will test again, if it does not get to at least the performance of my old pc the motherboard is going back to newegg and ill be heading to microcenter to grab a 7700k and a z270 board.
No Iam a gammer mostly so I prefer horsepower over quantity of cores, but I see the value in them, probably in a few years I will be singing another tune, but in the next 1-2 years I dont think so, still there are so games that are pushing the envelope like Doom and Battlefield I
