Try lowering:
TRDRD_DD/DR to 5
TWRRD_DD/DR to 5

*since you are running 8gb DIMM's they will be sr so really DR won't do anything (i'd put a 0 to it) but DD will.

For stability and there is...

Rule of thumb for VTT on auto is HALF of vdimm. You basically undervolted it there with 0.75v (making it equivalent to 1.5vdimm) with your 1.53vdimm. Id recommend something like 0.79vtt :)

By...

From what I know & tried for certain with 3 different kits (2x16 3466c16, 4x8 3600c16 & 2x16 3600c14), even at IOL 5/6 you will likely fail MOST stability tests and you are running IOL of 4/3... An...

that's correct alder lake is a whole new architecture/processing fabrication. Best to hold out for the end of the year and splash big on a new system and ddr5.

Thanks Nah I left enough clearance to beable to install and uninstall diff kits of memory.

Yep it is on and did this in TS: http://www.3dmark.com/spy/17560878 & this in PR: http://www.3dmark.com/pr/794307

Urm.. warzone tonight it was hitting around 43-45 degrees with 22-23...

I suspect your IO-L's are too tight/low for stability try loosening them up to around 7.

Also increasing dram VTT to 0.755v - 0.8v could help with out needing such high vdimm.

@Braegnok any update on your ram? I wasn't able to get 4200 16-16-16 stable via HCI mem test yet.. But managed 16-17-17 might switch back to 16 flat again and try a few more things but keener on...

@Braegnok any update with your ram settings/stability etc?

Did you go maximus tweak mode 2 yet or is it left on auto? I noticed your RTL/IOL is trained nicely.

Got my kit today can’t seem to...

tRFC & tREFI generate a fair bit of heat, especially from a long run high-temperature stability stand point.

tRFC & Trefi Â*should be the last values to tweak.

Tune secondaries down it will increase testing speed and performance same with tertiary groups

DD can also be 0 afaik as you are just running 2 sticks.*

You should probably ramp up your uncore...

17 flat should be easy at 4200 with that kit people have even managed 16 flat afaik.

4300 or 4400 headroom at 17 flat should be in the mid to high 65-67gbps read write bandwidth and approx sub...

heh my bdie 4x8 16-16-16-36 refused to run past 4133 at 16-18-18-36 or 17-17-17-36 timings.

I wonder if our new sticks can handle 4200 at 16 flat....Â*

sounds about right. 4 sticks is more strenuous on the IMC with overclocking RAM 2 sticks is the best way to go.

Funny enough I just ordered a new set of 3600 14-15-15-35 gskill as well and it's 2x16 too (F4-3600C14D-32GTRS). Hoping to dial it up to around 4200-4400 with decent timings...

Your latency is okay but could be lower IMHO did you tweak TXP/PPD? IMHO your bandwidth is lacking for 4200...

At 4133 with the new 1003 bios, this is what I get... For some reason, I couldn't...

Still, on 901 and running 4 sticks @4133, I think there is still an improvement for you there are some values of mine I could probably tighten too but haven't bothered yet.

Anyone figure out how to define RTL CHA CHB & IOL CHA CHB?

Every time I try to put a value in there even mimicking the same as the auto or a value I know works mem training just fails and won't...

Thanks, Shamino seems to show incorrect values when I launch it though :(

^thats much better once you screw down the RTL/IOL's (not really mentioned how on either of those guides) you should see your latency dip under 40ns.

Also PPD and TXP are great values to setup to...

I don't think you done much in the secondary and tertiary space of timings?

What did your memory training of RTL/IOL turn out to be?

As mentioned previously you should use asrock timing...

IO_Latency_offset 21
CHA/B RFR Delay 14

Train your

RTL CHA 61
CHB 62
IOL's to 7.

what are your secondary/tertiary/RTL/IOL's? - asrock timing configurator shows most of it.

Does anyone know what tRFC cycle time 2 & 4 in Asus bios should be?

Should it be equal to tRFC or less? What's the maths exactly?
