Right now im soldering the rest of these CherryMX keyswitches into my keyboard then Ill post some benchmarks and such in the CH7 thread. Been working 12+ hours a night and testing then sleeping in what little time is left.
Almost took few days from work to have more time to play myself still got 9 days to use up by end of September. Forgot to ask what POWER settings are You using with Zen2 ?? I'm on the LLC4 cpu 400khz very fast LLC3 soc 400 fast and 400khz on memories. Not looked in to tweekers section yet.

Never used it, tried it now and got this. I'm guessing it'll appear on the results page soon.
In any way, it looks like the program only uses a single core, judging by the low read and write speed, latency looks very weird as well to be honest.

Yes, but I'm not classified.

You can uncheck the boxes and test Read, Write, and Copy separately. Do it on one until you think you've reached as high as you can for it then uncheck that box and repeat the process for the next ones. See how high you can get. You can also set core affinity in Task Manager to find your best core for each test. It's kinda fun to play with and see how high you can go.

My bests are:
Read -- 33811
Write -- 32210
Copy -- 41339
Latency ~ 28ns

Glad this got an update, now I just have to find maxxmem results from a few years ago to compare. I think I remember my first PC, i3 530 etc, getting around 8gb/s if my memory isn't failing me.

Some results for TR 2950X with 32GB / quad-channel @ 3466. Only difference is performance pre-select in Bios. Memory is Sammy B-die and this setup has run 3600 / quad at stock RAM voltages, but at reduced timings (will try to run the updated MaxxMem2 bench on that later)

I'm guessing this is pretty normal for my ram.
Haven't bothered with any ram overclocking.

Hi, guys, I made some discoveries.

I thought I try an attempt to get my previous setting stable before upgrading to 3000 series.

The thing I tried differently this time was to leave geardown mode on auto, and sure enough, my previous ram OC is stable once more!

However, on my new 3600 It seems unstable with 4.2Ghz with 1.375v. I'm not sure how far I can push the voltage, or perhaps the BIOS is not matured enough to reach higher speeds?

__________________________________________________ __



There are a few rules that zen 2 users should know


1) FCLK should always be equal UCLK and MEMCLK , otherwise, domain synchronization reduces system performance.
2) VDDG <= SOC . Max limit 1.15 volts , which you may need.
3) procODT for all Zen 2 changed and the optimal range is as follows (for all motherboards) 28-40 Ohm. Settings from the previous generation of processors are not relevant (except for timings and voltage).
4) PB2 (+0 + 25 + 75 + 100 +200 mhz)not equal PBO. I advise you to use PB2, this algorithm does not depend on currents and thermal packets. The only limitation of this technology is processor temperature and FIT. Do not forget to turn off the PBO.
5) The optimal processor temperature for maximum boost is 60 degrees or less.
6) The maximum frequency of the memory controller (stable) in most cases is 1866-1900Mhz.


P.s. I have notified AMD of all existing problems, no need to worry.

P.p.s. Review. I have lost a lot of time due to thorough research of new products, but the review will already be published on all resources early next week.
Then I will engage in tight communication with the community (I hope the availability of processors will improve).
