Thanks guys, I enabled round trip latency training and dropped tRCD and tRP to 14, and tRFC to 374 and achieved the following at 3733 x 4 . Ran memtest included in BIOS and it completed 4 passes all good.

Chip seems like a decent one:

Thanks for your help guys. I would really appreciate any more tips you can offer for memory. Once memory is sorted out I'll work on CPU boost frequencies.

Um...a kinda stupid and little OT question: the time I set to UTC+2 in BIOS will occasionally/frequently be reset to UTC+0 even if I do not reset BIOS settings. This occurs with both M13A and M13H. Did I miss some switch? Is this a bug?!

Memory Timing TRAS Fix and Improve system performance
0801 and 0070 bios Can be set below TRAS 28

ROG MAXIMUS XIII HERO 0801 BIOS
ROG-MAXIMUS-XIII-HERO-ASUS-0801.7z

ROG MAXIMUS XIII APEX 0801 BIOS
ROG-MAXIMUS-XIII-APEX-ASUS-0801.7z

ROG-MAXIMUS-XIII-EXTREME-GLACIAL-ASUS-0801.7z

For SUPERPI and Windows 7 support (APEX 0070 BIOS)
This is an old BIOS, so it is recommended to use it only when running SUPERPI. Because the latest BIOS has better performance

What sort of dram voltage are you running for that? Great results. What SA? I'm just after tips and hints. This is a 24/7 gaming rig, but I don't mind pushing it along with voltages.

Also what's the RKL consensus for gaming rig? Higher memory speed 1:2, say 4266 to 4800, or much tighter timings 1:1 3733-3866 ?

bios/uefi time will sync with Windows/OS time as far as I know.

Oh...I thought it was the other way round?! Point is that Windows will in most cases be 2h off and appears to be lazy to sync with the web. Therefore I have to manually force sync time. With Linux this is usually not an issue, because my Ubuntu install will sync with an NTP server upon boot/login.

This will to some degree depend on game and settings, but it appears that most games will prefer Gear 1 due to the lower latency. YMMV, though... ;-)
Ok thanks, think I'll settle on 1:1 speeds then. Plays nicer with 4 sticks.

What about BCLK OC? I don't see a way to lock it to 100 for everything else besides CPU and mem on MH13, am I missing something? Will push it to 102-105 for a little extra mem and core speed if possible.

Hey guys

Does this sound like my 11700K is dying?

Have been running 52, 52, 50, 50, 49, 49, 49, 49, 49 quite happily with 100:133, Gear 1, 3733MHz DDR4 @ 1.4V, Adaptive Voltage at 1.45V LLC5, VCCIO 1.05V, VCCIO OC 1.35V, VCCSA 1.25V and I had a game crash last night after which I couldn't POST at the same settings. Kept getting 55, 5d, 38 and 3A errors on the board. Been able to get back in today by setting VCCSA to Auto which according to HWiNFO is at 1.376V now. I haven't tried any games as yet as this is not really a comfortable voltage?

Is there any new bios for SR B Die in sight that I might be able to go beyond 5000?

This is now stable on 0705:

1h GSAT. 1 Prime Custom. 10.000% Karhu. 400% HCI

2x8 4800 17-19-19-39-296 - Gear2 - 1.525VDIMM - 1.10V MIO - 1.10V SA

Well I need to set the VCCSA to 1.44V for 3866. It´s normal.

I suggest you update your BIOS to 0707 first, because I'm getting ~42.5nm with a little lower R/W/C on 4800-18-18-18-42 CR1. That is, if latency matters for you... ;-)

I guess you have a fixed cache ratio?
I was told 0704 to 0707 is the same basis.

Will bios equivalent to 0801 and 0070 be released for Maximus XII Apex?
