14 cycle TM5 failure

[LowBlow]

What should I change here to get this OC over the line please? I'm aware that error 2 is a de-sync issue possibly corrected by voltage but I don't really want to feed any more voltage into this as I plan to daily this OC.

Thank you.

Does tCWL 14 and SCLs at 4 pass? tbh I'd drop tRFC significantly before thinking of dropping tCWL below 14, just somewhat strange list of priorities

If this wasn't a Gigabyte board first thing I'd do is try 1.56V........but knowing Gigabyte overvolts every board's VDIMM, if following the usual +0.03V estimate it might be getting close to 1.6V. Otherwise I wouldn't see an issue with 1.56V, seeing as you're below 40C while 7 hours in TM5

Or do tRRDL 6 and tWTRL 12, might be able to save you 0.01-0.02V.

Worst case tRCD 15 or 16 if you can't afford the VDIMM increase? May not have to touch tRP with it yet

5800X3D is not the best CPU for B-die to stretch its legs anyway (Fabric and RAM matter less) so I wouldn't be too bummed about running flat 15s, 14-15-15, or dropping down to 3733CL14.

Change tCWL from 12 to 14. RDWR should Automatically go down if its on Auto.

tCKE 8 may help if it makes things worse then change it back to 1


Although GDM is on try with ClkDrvStr 40. Do this last. Its not good to make too many changes because you wont know what helped and what made things worse.

Just out of curiousity, could you run DRAM calculator to see what will it recommend?

Not recommended for ZEN 3 CPUs its only suppots up to ZEN 2

@LowBlow
Also forgot to add TRAS should be 28 and RC 42.

So there's no chance it will make a suitable config because of Zen 3?

You can only use it has a starting point. But it usually gives wrong ProcODT and other voltages which work and is ok for ZEN 2 but will can cause problems on ZEN 3 CPUs.
You may get lucky and get a profile to work if its a safe profile. Most of the timing settings are OK but not the other voltage settings.
