The good chips like volts. The good air chips usually do not and that is why good air does not always mean good ln2.
Just like i told you on xs flanker about your great air thuban chip
Case in point my 1400 does 4150 cb air. -40 Cold it does 4400 cb same volts. More voltage = nothing.
These are just like llano...scale with cold hardly any scaling with voltage.
If anything binning for voltage tolerance may prove to be usefull as well as binning for -40 cold imc that does not drop threads over 2666 in prime 95...
Performance wise its not about how high the core can go....its about balance...
-40c 4.4 w/ tight as a virgin 2666 mem CB lost to air @4.150 w/3600 mem in my testing...
You can see the same thing happening in the 32m pi low clock challenge...
Zen is raping 4.6 + ocs @ 4.2 on air...except mine because im chasing a balance...@ 4.5 it would be very close between us..
Of course the balance will most likely limit your chips top possible OC...but if higher speed cpu/low ram is slower....why bother..
Above is boot run barely stable just happy it completed...cores were not really happy with 4.6.
This is r5 less cache tuned to the max run and better timings...
Ok after extensive testing i have come to the conclusion that.
1. I am not crazy yet in the sense that i have not completely lost my mind.
2. The above run was actually very fast for R5 1400.
3. R5 1400 is much slower due to less cache and thus needs way more memory power to match R7.
Will show an example in a few.
No. I won't bench hardware that i am supposed to review until it has been reviewed. Just a set of trident z.
Ryzen effeciency is an odd thing.
The above run is slow for 4.6 imo...but fast considering the temp range i am in.
Probably best to gauge like this.
DI/cascade hardest
Phase hard
Ln2 easier
Air/water easiest
Seperate cooling categories then compare by speed.
Basically people on ln2 should not be losing to people on phase or cascade...it's very possible for a good chip to beat phase at much lower clocks on air/water.
Llc 1002 bios
Bios set 1.4v LLC 5 optimized phase control....not extreme ( are you on ln2? No...then do not use extreme)
Load @ measure pad 1.44-1.45
Load @ socket 1.40-1.41 idle 1.39.
Speculation without even owning this particular board?
Priceless.
Using software to monitor voltage?
Silly.
Dmm at board read points = wrong.
Just some fyi.
Socket or dont use it as a reference because its innacurate.
@ socket i was seeing 1.40-1.41 load set 1.40 lvl 5 llc.
Probably lvl 4 is better for 24/7.
Ignore cpu-z idle right load wrong.
Here you go.....taichi 1.94a
2x 16g Dual Rank PC 3200 @ 14-14-14-34
Ok so its bench stable big deal right?
How about pretty damn brutal 13+ hours stress test stable?
I did not hit a hole infra but i can say this on dual rank.
At 3390 i was over 1 sec faster in 32m pi then 3420.
Coincidence? Doubt it. I think its a strap or performance related memory hole. Imc was also failing just over 3400
Recently swapped....even better.
Collecting results atm....
3200 14-14-14 running prime stable....preety impressive for pc3400 16-16-16 bin....i would expect 15-15-15 3200@ best for that bin normally...
