been trying to get 3866 1T stable. its difficult
Just tried with 4000C16D-32GTRSA, 0707 bios. Couldn't even boot. Will try mode 2 later.

Any thoughts on Micron RAM OC on RKL?


$105 for Crucial Ballistix Max 4000C18-19-19-39 1.35V kit, wonder how well this would overclock. Mostly see Bdie and DJR in this thread.

Asus M13H has this kit on the QVL at 1,2,4 dimms.

Based on my exp, 16GB version would be better than 8GB ver., or you can try 2*32GB, 3600C16 kit.

Hey guys currently running 11900k (5.1 all core) w/ Maximus XIII Hero (801 bios). Ram is G.Skill F4-4000C16D-32GTZNA (16-16-16-36) currently running at 4266 (16-17-17-37). I tried the following:

Gear: 1:1
DRAM Frequency: 3733 mhz
100:133

DRAM voltage: 1.50v
DRAM VTT: 0.750v
Mem I/O VCCIO voltage: 1.35v
CPU System Agent Voltage: 1.30v

{DRAM TIMINGS}:

DRAM CAS# Latency [15]
DRAM RAS# to CAS# Delay [15]
DRAM RAS# ACT Time [35]
DRAM Command Rate [2N]
DRAM RAS# to RAS# Delay L [6]
DRAM RAS# to RAS# Delay S [4]
DRAM REF Cycle Time [300]
DRAM REF Cycle Time 2 [Auto]
DRAM REF Cycle Time 4 [Auto]
DRAM Refresh Interval [65535]
DRAM WRITE Recovery Time [12]
DRAM READ to PRE Time [6]
DRAM FOUR ACT WIN Time [16]
DRAM WRITE to READ Delay [Auto]
DRAM WRITE to READ Delay L [Auto]
DRAM WRITE to READ Delay S [Auto]
DRAM CKE Minimum Pulse Width [6]
DRAM Write Latency [14]

PPD: 0

Which boots into windows for the first time just fine and runs stable, but if i reboot the computer and or turn it off. The computer will never post again. Any thoughts/insights?

@cstkl1 and others: I recon there are/will be F4-4000C16D-32 and F4-4400C17D-32 kits - if I'm aiming for G1 3866 with as tight as possible timings - which of these would you suggest for 11900K & M13A?

Furthermore, the GTRS, GTZA etc. naming stuff - is this of any relevance except the show-offy heatspreaders?

Cheers,
r.

@roooo Are you currently able to run 3866? I cant even boot 3866 gear 1 with z590 Apex/11900k. I figured it was just me missing something but then I see some others limited to 3733 Rocket Lake 32M Pi Tweaks for Noobs "Gear 1 needs binned to max out. 2 out 12 CPUs I have can do 4000 12-11, only one can do tras under 28. Some wont even train 3800 12-11"

Oops, really? Then maybe I won the lottery this time :) I can do 3866 with several kits: F4-4600C18D and F4-4800C18 (both 2x8GB) and Ballistix 4400C19 (2x16GB). All will do G1 3866 CR1 with more or less tight timings. The Gskill kits will do 14-15-36 HCI stable, Ballistix only 16-17-44. However, I had a Klevv Bolt XR 4000 kit that would not boot 3866 either. What BIOS are you on and did you already disable this 1D read voltage thingy (can look it up if you don't know what I mean)? I'm on BIOS 0801.

Edit: I just ordered F4-4000C16D-32 and will report back as soon as I have tested it...
Edit2: My 11900k is SP82, if that matters.

I have tried 3866 1t and 2t with bios 605, 801 and 707. With 1d read voltage disabled and all kinds of other settings enabled and disabled. I have bottom barrel 11900k. SP 54/55 depending on bios.

That don't sound good. TBH considering time & money you already put into it I would sell it and get another one...can't get much worse, can it?! ;-)

@roooo How high have you been able to run DR bdie in gear 2?
AFAIK all of the above kits are SR. It got the F4-4800 to post at 5330, boot at 5066 and HCI stable at sth like 4800-18-18-38 CR1 but did not try really hard because 3866 gear 1 tight is the way to go for me. The Klevv kit would do 5066 semi-stable but with quite loose timings (22-25-54?). As I posted some time ago, I figured that the F4-XXXX BDie kits are very sensitive to a too high VCCIO MEM OC, thus I hit a wall when driving them with more than 1.27V. Vdimm was 1.6V, SA 1.40V IIRC.

I haven't been able to run higher than 4800 on SR with 11900k/Z590 Apex. I see other running 5000+ on SR so I would think it is my CPU but weirdly enough the 11900k would run 5000+ in z490 Apex. :confused:

Happened to me too, there's a bios option somewhere called "Boot Voltages" and increasing my vccsa and vccio mem oc boot voltages fixed the issue for me. I guess those voltages need to be higher during boot than is needed in windows.

Probably required for Re-Training subs @ Boot ?!

I got Crucial Ballistix Max SR 4400 CL19 pretested @ DDR4-4800 CL18-22 with 1.45V with Ryzen.

See what they do with another 11700K on M13A by end of the week.

Nvr had problems running DR 3866 on M13A. I have tried several chips with SPs 78,80,95

Currently running DR 3866 15-15-30 1.45V, IO1=1.1V, MCIO=1.2V, SA=1.4V.

11th gen has a large deviation in the IMC quality. If that is an SP55 chip I would just sell it. No chance for a good IMC to be on that terrible silicon.
