However..... For "Safe" settings it gave a tFAW of 52 wich is plausible
But i think your right in saying that the calculated tFAW values should be looked at again
Things don't sum up correctly

Think you should use 3466 as frequency... as that's the strap you want the settings for
Your sure you entered the XMP values for tRRD ?
They seem a bit on the high side (in your screenshot)

@1usmus
For me the calculator shows "to high values" on both presets so there is definitly something not right in the formula's
tFAW should be between 4x and 8x tRRD_S
Perhaps you should also add a value-ceiling in the outcomes wink.gif
As the board can only handle values going up to a certain number (different for each timing)
You should be able to extract the maximums from the bios with the tool you used to enable a certain menu

Best program to test SSD's is Anvil IMO, it shows all the speeds and you can check SMART Data as well.

you can't boot with CSM disabled because you haven't installed Windows in UEFI mode but in legacy mode.
where do you see SMART counters in Anvil?

do you see your drive in BIOS section Advanced/NVME information or in Advanced/SMART?

Been running a memtest for the last 3 hours, zero issues detected. So that is something.

AIDA doesn't really show any improvements over my 3046MHz 14-14-14-34 1T though, but uh - they're running at 3200 now.

Am going to push my 1800X back up to 4GHz though, instead of 3.8 - or possibly 4.1GHz (been running at 4050 for a couple of months). Anything I should be aware of, with your settings, that might interfere with this?


Also, I did however not have these settings available in my BIOS(?)
MemAddrCmdSetup_SM [Auto]
MemCsOdtSetup_SM [Auto]
MemCkeSetup_SM [Auto]
MemCadBusClkDrvStren_SM [30.0 Ohm]
MemCadBusAddrCmdDrvStren_SM [30.0 Ohm]
MemCadBusCsOdtDrvStren_SM [40.0 Ohm]
MemCadBusCkeDrvStren_SM [60.0 Ohm]

But, I'm guessing those might be either 1701 settings, or the "mod BIOS " from the google docs link? (Am on 1403 atm).

Update:
Running at 4GHz again, at 1.35V, with the same settings as provided in the above link, the Voltage for 3.8GHz caused the computer to insta-turn-off while simcrafting - I found Simcrafting to be a great way to test stability tongue.gif.
CPU Load-line Calibration [Level 4]
CPU Current Capability [130%]
etc.

I was unable to stabilize 3333 when overclocking the processor more than 3800 MHz +, the noise "CPU VRM" affects the signal quality
In the modified BIOS open the "PCH" menu, there are no more differences. It is necessary to use the last bios, otherwise nothing will turn out

Thanks forfinfing time to answer. Not taht good with DDR overclocking. Calculator is new to me just used brutal classic way always. Onetiming down memtest next timing down memtest ect. On Sandyplatform took me 2 weeks to get tightest timings possible going biggrin.gif


Anyhow Off to Trance Rave :]

tRRDS и tRRDL these are different values, by default for the slowest chips "ns" will be 3.700 and 6.000 maximum. In the new version, I will protect against too large numbers smile.gif

Finally got around to try out the keyboard fix and test/try out the calc's timmings. for the most part the timmings it crunched out works (Always gonna be some level of error)

Here's what it calculated based off my ram set: G.SKILL TridentZ RGB Series 32GB (4 x 8GB) 3200mhzCas14 Model F4-3200C14Q-32GTZR



And with EC1 9458 and Bios 1602 I managed





BLK: 104.5
MemSpeed: 3344
DramV: 1.45 Extreme manual 300khz
Soc: 1.2 LLC3 Optimized
VDDP: 1.005
VTTDDR : 0.726
VPP_Mem: 2.52
CLDO 900
Cad Rec 3 from Calc

unfortunately I could not get it to boot and stick without gear down mode enabled and I had to bump ras up by 2 for stability after erroring in I also dropped any modifications to proc and rtt as that would refuse boot and stick as well.
Unfortunately Windows 10 with the falls creators update with these timmings still hangs a bit when it goes to start explorer after login, similarly to how it behaved with my settings that were rock solid on the last windows update. cad bus seems to effect this to some degree as I get variances of initial system hang with 30/30/40/60 24/24/40/60 and default on my previous settings. with this being a bit more solid I'll be screwing around with cad way more tomorrow and see what I come up with. It might be that I was on to something and that aura and classic shell was also effecting this but I didn't methodically poke that line of thought with any sort of concrete testing so....

also fairly certain, given when I checked with the old setting when I updated, my score would be higher if it was the last windows update but..



slowly but surely getting to 170 cp biggrin.gif

1) I did not investigate memory behavior during overclocking via "BCLK"
2) "tRFCns" 320.000 can not be, it is either 260 or 350 depending on the chips.
3) high voltage "VTT DDR" helps to deal with errors, but friezes appear in the system

I repeat, this occurs when the SPD is incorrectly read, 8.000 and 9.000ns can not be

From UEFI 1401 (13/06/17 onwards) the UEFI have options to tweak CAD Bus. The options originally were exposed within Advanced > AMD CBS > DDR4 Common Options > CAD Bus Configuration. IIRC from UEFI 9920 (21/07/17) they have also been exposed in Extreme Tweaker > DRAM Timing Control.

Aha, so that's why i am getting SCSI in devise manager perhaps.

Its in Anvil under system information, there is a lot of data there.

More info on SMART data can be found in this program: http://www.hdtune.com/

upd
@lordzed83 DarkLordThe1st

for example

Intel XMP by default works with 2T command rate. Ryzen profile works with 1T. Difference between 2T and 1T (1.5ns vs 0.938ns max 0.666ns min)

2T/1T = 1.5 / 0.938 = 1.6 and 1.5 / 0.666 = 2.25

Intel XMP tRRDL have 9 ns for 2T and 9 / 1.6 = 5.625ns for 1T Ryzen
for tRRDS 9 / 2.25 = 4 ns

was that English? lol, 1T > 2T right?

on a side note, i got some thermal grizzly kryonaut last night, applied it, temps went down for about a day and then i booted my PC today and i was hitting 70c! im out of thermal paste so i cant even add more frown.gif $12 for 1g is such a rip off lol

I'll try taking a look into that, thank you! I did look for them in the AMD CBS menu, but must have missed them.
Can anyone explain what these settings actually does though? Am curious.

The:
MemAddrCmdSetup_SM [Auto]
MemCsOdtSetup_SM [Auto]
MemCkeSetup_SM [Auto]
[...] etc.

I'mma google.

Command rate (CR)
The amount of time, in cycles, between when a DRAM chip is selected and a command is executed.
