Hello fellow enthusiasts!
I'm reaching out to the community to get some help choosing in between 6400 and 8000 for my rig (9950x3d on a Tomahawk x870e with G.Skill cl26 M-die).
I got a nice memory kit and I'm now trying to figure out what the best timings and setting would be to run with this combo.
You may recognize these timings, I'm using buildzoid's lazy timings for 6400 (not really sure how to further tighten that up so suggestions are appreciated) and easy timings for 8000 (as the more aggressive lazy variant is unstable for me) – again suggestions on tighten these are welcome.
Also there are a few BIOS settings I'm unsure about:
- GDM – if I disable this the system becomes unstable (errors on y-cruncher)
- TSME – does this affect stability or just adds a minor penalty to latency?
- Data Scramble – not sure what this does but switching it off makes it less stable
- BankSwap – when I select APU I get better performance but also less stability
- fch spread spectrum – again less stability when switch this off
With above BIOS settings I found that when I tried on a better MOBO (Godlike x870e) I could disable all of them and still get stable results, in fact I couldn't even find the 'fch spread spectrum' setting on the Godlike to disable… but on my MOBO disabling makes it less stable.
Performance wise I get the following:
- 6400
- 66.1ns latency AIDA
- 6.968s PyPrime2.0
- 8000
- 67.7ns latency AIDA
- 7.082s PyPrime2.0
