so.. if we set affinity manually, the CCX issue could be reduced, right?..

And it seems like running in balanced mode only uses half the cores and threads. For me its 0-3 (meaning core 1-4) but i am not sure at all if the cores are evenly spread between CCXs, if 1-4 is on one CCX and if 5-8 are on the other.

process lasso and cache man are easy ways to set processor affinity - according to Outertech

"Since we are expecting a fix from Microsoft on this issue we have decided against an automatic Cacheman optimization at this time."

so, we can do it manually; with software or wait for microsoft.

Would mean Microsoft finally got their stuff together and fixed w10 and ryzen. His memory latency and speeds look god awful though.

Cinebench can be "hacked" to boost scores. wink.gif

hmm... but there's local guy asked why there's little to none improvement on gaming by setting the affinity manually headscratch.gif

code related?

Oh that too but you can also set affinity and get higher scores, same with Asus bios you can set the performance bias to cb15.

depends on the affinity - 0-7 - and 8-16 are differnt CCXs - if you set all affinity to all real cores (and not SMT cores) on ONE CCX (assuming you only need 4 threads) and nothing changes, then smt/ccx's arn't the issue for that.

the problem is - doing this manually is a pain, as you have to make sure you balance the SMT cores, the CCX's - and the # of threads (and spawned threads) - so... really we microsoft to fix it. (or cacheman)

hmm.. would like to ask that one but seems like i'm facing a fanboy.. might just leave him headscratch.gif

pretty sure you are talking about the H110i GT, not the H110i GTX

but then you get into the CoolIT vs Asetek debate;
is the 2 year old CoolIT design better than the Asetek Gen 4? (and now gen 5 with the x62/H115i)

Soo...
4.1 Ghz at 1.39vcore?

Will it hold?
