Edit: pulled my usb gsat and did a run
Drooped one of the timings and tweaked a few more
On that test
Looks real good to me. tRCD below 20 not stable? That tRAS is likely subbed since it is shorter than CL+RCD+RTP (all three operations have to complete within the ras ticks, and if ras is too low it cycles or, more importantly the bios microcode subs in a value to correct the timing error - which is not reported to the OS.
I managed stable 4200 with a 9900X (and 64GB, no less), but alas, using the same sticks and R6EO board, this 10980XE can't manage 4000, so I run 3733 c15 (which is pretty low true latency). The issue with 4200 and 4000 with this 10980XE is RTLs. Can't get truly stable low RTLs over time with >3733, and since these are the most important "timings" 3733 actually performs better overall. My 7980XE/R6 Apex is happily humming along at 4000c16 with very tights secondaries and RTLs. It's been in compute duty for 3 weeks now, non-stop with 3 Titan Vs. Zero reason to tweak anything on that rig. [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
Some screen shots:
Nice tho but i see your dilemma it makes sense tho i can do 125-130gb reads as it is still limited even when i run high multi and higher mesh i guess once you are in the 50-55ns you can call it a day in x299 even if your ram/cpu/mobo cant do better.....
The problem i have with that 20 or +3 over cl at the beginning i didnt understand why i cant lower it down on par with the other 2s.. Till my board went to heaven with a permanent code FF....
When i started cleaning everything around.. I noticed one of my sticks on the gold contacts theres a few of them that are pilled off.... The gold plating felt partially off... its not burn its been like that since day 1.. i never check them when i bought them but im sure it was like that ot it felt off.... but I never cant have stable that particular timings above lets say 3700mhz is always 3 ahead of cl.. Sometimes when i start droping down rtls that particular stick dissapear out of the 4 he is a kind of a maniac by itself. So when i notice the gold contacts i did a mem run without that stick at that time on my asus x299m on tri channel and hold and behold the timing sticked on the stress test without errors..
I can rma but i don't know if gskill will return me a same set of sticks that perform the same... This 2 kits of bdie do very nice timings i bought them together.. Trfc i can drop them as low as 300trfc with 4200MHz under 1.45mV even do 1t at that speed as well.. So its a gamble for me at this point so i just deal with it like that, to me its not that important in this system.. It will drop the latency a tiny bit but if i get another kit and i cant lower trfc as low then its like the same in the end...
I can try to plate the gold back.. I have done plating in japanese swords parts before its not that hard. But the plating kit was over 100$ back in those days... dont know exactly now i supposed it's higher now..
I left it running on ramtest still running it was like 18000% when i left to work [email protected]
trfc is at 320 im tightening that one and tfaw as low as 12 the rest of timings auto is putting low ones on this board i will see.
Edit: well it passed with flying colors
im going to make the tras 38 and see if i can lower that trfc more at least to 290-300 if possible after some other tweaks..
rtls are 65s/10s @ 4200 all of them i can boot at 4400 but loose 2 sticks in the process try once just to see want it to make sure first 4200 was steady
