Really amazing numbers for Zen 3 and congrats on the max Fclock with those super tight timings

Anyone know why there's such a dramatic reduction it write speed between X470 + R7 2700 vs X570 + R7 3700X using the same G Skill TridentZ RGB F4-3200C16-8GTZR x2

X470 + R7 2700 = 44.66GBps

X570 + R7 3700X = 25.61GBps

it's nearly half the read speed vs only a couple of Gigabytes off on X470 anybody have any idea as to why or how to fix it or is it not worth worrying about

4, 6 and 8 core Matisse and Vermeer CPUs have halved write speed. It's part of the design, something to do with the width of the IF bus from chiplet to I/O die. Nothing to do with the board or chipset you choose.

Ryzen 2000 and 4000 are monolithic dies, so have full speed write.

Copy speed is what's reflective of your real world performance. R/W matter little outside of benchmarking numbers.

Ah right o then still seems a stupid idea on AMD behalf but doesn't seem to affect perf in everyday usage but seems funny that the Vermeer based CPU above my post gets almost the same read/write/copy speeds no big drop off in write speeds there did AMD fix something so that blows your "Vermeer CPUs have halved write speed" speed theory out of the water doesn't it

Like I said, Write is more theoretical so it was a calculated risk by AMD.

No it doesn't, because if you'd actually read my post, I said it applies to 4/6/8 core SKUs, so single CCD chips. The 5950X is not any of those things. It's not a theory if it's literally a well-documented design choice

I've recently got into manually tweaking my RAM. I have the Corsair CMK16GX4M2B3000C15 Vengeance LPX 16 GB RAM modules. I've currently set it to run at 3200MHz and adjusted timings according to what the Ryzen DRAM calculator suggests on the FAST preset. So far it seems OK in memory tests. I managed to run it to 1600% with 0 errors (HCI Memtest). However, I am concerned about the memory latency readings I am getting. I'm not sure if it's expected for what I have.

Here's a recent result:

Here's my current timing settings:

Just want to make sure I'm not doing anything that's going to negatively affect how my RAM performs.

Just messing around..

Kind of weird ocing memory on this platform. I added my other two sticks for 4x8 total, loosened my timings and I get stronger reads and copies. L3 bandwidth took a hit because I'm guessing it doesn't like the looser timings. Too bad my Black and Whites wont tighten up as well as my Royals.

 

[sam_86314]

Got my memory to be stable at 3200MHz after an overnight MemTest86+ run (and didn't corrupt my BIOS this time).

 

[mikalo]

unfortunately can't overclock anything...

New CPU

New CPU

Didn’t you already swap CPUs before from the tech purchase thread?

 

[freeagent]

Playing with my memory a little.. just 2 sticks

Dammit cant get passed 62ns lol

Yes just didn’t post new results here

 

[dont whant to set it"']

Yeah, so ... , 1.4V Dram , 1.2V VSoc .
My heatsinkless ddr4's do not care much for voltage when it comes to heat output , having 16 512 MB chips per dimm.

 

[dont whant to set it"']

2000MHz InfinityFabric Clock? .....ck me silly, I had speedier ddr4's at hand some time ago. Attached bench run was run with D.O.C.P. timings, mostly, apart from tRC reduced by one to 67 and the tRFC from auto to 448, everything else timings wise: auto(1.35V Dram voltage). All due to the new microcodes and improvement on previous ones I guess.

 

[Dark_ice]

Old 3930K faster than Ryzen in DDR memory test

 

[dont whant to set it"']

@Dark_ice

Different, different , so , and so forth , many differences.

 

[freeagent]

Old 3930K faster than Ryzen in DDR memory test

What's with the high latency?

My X5690 and 3770K can do better in latency, but that's it.. they get creamed in everything else

 

[sam_86314]

My nostalgic PC with its shitty 266MHz RAM.

Currently looking for 4x1GB DDR-333 or better, but I don't want to spend too much on it.

[phanbuey]

Stabilizing an Intel cache/memory OC might be one of the most tilting things in PC building...

Seems like I have this one stable after days of stress testing, final result.
