Low effort Single rank Hynix 16Gb A/M-die timings for Ryzen 7000 at 6000Mbps
🕑 Added 2023-01-25 00:03:23 +0000 UTCThese timings should work on pretty much any hynix based DDR5 kit that is currently available(16Gb M-die and A-die at the time of writing). At DDR5-6000.
Voltages
VDDIO / MVDD / MVDDQ: 1.35V
VSOC: 1.25V
Timings
tCL: just use XMP
tRCD: just use XMP
tRP: just use XMP
tRAS: 30*
tRC: 68
tWR: 48
tREFI: 50000
tRFC: 500
tRFC2: 400
tRFC4: 300
tRTP: 12
tRRD_L: 8 // Some hynix A-die really really sucks at tRRD_L
tRRD_S: 4
tFAW: 20
tWTR_L: 16
tWTR_S: 6
tRDRDSCL: 4
tRDRDSC: 1
tRDRDSD: AUTO (only relevant for dual rank)
tRDRDDD: AUTO (only relevant for multi rank)
tWRWRSCL: 4
tWRWRSC: 1
tWRWRSD: AUTO (only relevant for dual rank)
tWRWRDD: AUTO (only relevant for multi rank)
tWRRD: 2
tRDWR: 16
*This was previously 28 because the newest Asrock and ASUS BIOSes that I've been using don't enforce the memory controller tRAS limit of 30. This really doesn't make much of a difference to anything.

Hey Buildzoid, curious if these values still hold up as the "default" low effort OC in late 2024 or do you newer recommended timings?

Maybe now it's worth updating with values for dual rank?

no

Is there any changes to these timings for 9000?

I don't have any dual rank dimms ATM
realies
can you update these guides with example values for dual-rank kits?

I tried 8 8 and worked with 2 set of 2x16gb kits

First of all, thanks so much for the video and this. :) I ordered a 64GB kit, dual rank, hynix A-die it seems: F5-6000J3040G32GX2-TZ5N. Can I expect the same timings to work? And what about tRDRDSD and tWRWRSD? Keep auto or manually set to something? Still waiting on the X3D chips before I can test it.

no because the big gain with dual rank for DDR4 is due to DDR4 having only 4 bak groups per rank. DDR5 has 8 so in a way it's like dual rank DDR4 even with just 1 rank.

dual rank don't have any benefit at this moment, do you think it will make any later in the platform?
