Did you even read my last couple of replies?

That's one way to show that you read them. biggrin.gif Thank you for your continued input and responses to our questions, complaints, and comments, Elmor!

What do you guys think of the two ram speeds mainly for games, because business apps it won't really make a difference.

Latency is a derivative of frequency and timings. Once you get your head around that, the mysterious latency versus frequency debate (in the context of internet chit-chat) disappears. To compare timings and latency correctly, one would need access to all memory timings (not just the primaries), and also, at the very least have a basic understanding of the relationship between timings and frequency.

True, know that feeling of lack of time wink.gif .

@Ubardog @SpecChum

As said before I'm switching of rig when borked boot happen.

Press case power button > mobo power on > weird chirp from speaker straight away > mobo power down > mobo power up 3x post loop > clean beep denoting post > UEFI/DMM confirm ~1.5V on CPU VCORE.

As now I switch off PC at underlined stage on borked boot, hoping CPU is not getting ~1.5V redface.gif .

My belief is within the blue text stages CPU would be getting voltage what was setup on last shutdown, then as failed boot has occurred/detected "AMD CBS" has reset itself but Asus section has not (ie Extreme Tweaker page) as seen before. So the underlined mobo power down stage is where due to this "reset" a power down is needed to apply the changes of ""AMD CBS" and the red text stage onwards, due to this "reset" is where CPU gets 1.5V.

Do you guys get the same weird chirp on borked boot?

Normal boot for me is:-

Press case power button > mobo power on > 1x post loop > clean beep denoting post > rig go OS, etc.

What parameters should I change in order to stress test my CPU and RAM in OCCT and Intel Burn Test?
post #9935 of 17677
I know. I guess I should have said I can run at 3200mhz 14-14-14-34 or 3430mhz at 16-16-16-36.
So my question is in gaming where infinity fabric speed is most important to raise the low 1080p gaming
framerate issues compared to an i7-7700k, which of those two memory speeds will be faster? I think the 3430mhz will be faster because of the large increase in infinity fabric speeed and only dropping from C16 to C14, yet chew thinks going from C16 to C14 is more important like on an intel system. I just disageree, but want to see what others are finding with these memory speeds and a Nvidia 1080 at 1080p.

There are two parts to that question, the memory bandwidth can be measured. The actual nanosecond latency can presumably be calculated but a formula with all memory timings and frequency would be a bit of a monster. . I suppose framerates can just be compared.

The comparison is incomplete without looking at all related timings (not just the primaries). But for argument sake, given you have memory that can do it, why don't you run some tests and compare the performance?

I believe the question is more academic on this one. Is Infinity Fabric speed as relates to memory speed going to be a better way to get more performance than the pure memory latency. So, a 3200 latency 18 memory being better for overall performance than a 2400 latency 14 latency set of memory? This isn't just memory performance, since the fabric speed might trump the memory performance in a Ryzen based system. Sorry for the horrible grammar.

This isn't the comparison point the original poster is asking about. He's comparing a circa 200MHz hike, with a 2 clock change...hence my reply.

Right, from everything I have read and watched about memory performance for GAMING, the most important thing is speed. They were even showing 3466 and 3600 mhz ddr with C18 timings beating 3200mhz C14 because cross die communication with infinity fabric is 1/2 the speed of the memory. So that is why I disagreed with Chew. He may be right about tighter timings being more important for business stuff or photoshop/encoding, but for gaming everything I see points to having the infinity fabric which is half the ddr speed as high as possible is the most important thing. And frankly since Ryzen kicks Intels butt at everything else, but loses to gamiing at 1080p, I think sacrificing a tiny bit of tight timings that help encoding for a big benefit in gaming is the way to go. That is why I am hoping May updates allow 3600 mhz ram. I have a G.skill 2X8 3600 C16 kit, and if the update allows that to work, then I could bench 3200mhz c14 vs 3600 mhz c16 stabily. Right now there isn't much difference, but there are videos of guys reaching 3600mhz and gaming framerates get dramatically higher, like beating i7-7700k higher. What seems to be the big archilles heal in Ryzen is the two 4 core clusters need to communicate with each other faster thru infinity fabric, which runs at 1/2 ddr speed. That is the bottle neck and what is hurting it in games, whereas Intel uses the ring structure where they communicate much faster.
