TQ boss. Here's my timing



ProcODT 43.6
RTT_NOM RZQ/7
RTT_WR AUTO
RTT_PARK RZQ/5

Dram voltage 1.45
soc 1.14
others all auto
*I notice if i enable GDM the CL will become 16 even i set it 15. Is this ok ?

Hope can get better result

I thought u were on 2T CL15? Guess you already changed to 1T CL16 now?
Doesn't look to bad already if that's stable.


I'll just steal 'my' (stole most if it myself ) old 3733 4x8 config, if you got nice sticks it might work on 3800.
try this if you like:

ProcODT 36.9 (should do already)
RTT 7/3/1
CADs 24-20-20-24 (or 24-20-24-24, 24-24-24-24)
Vdimm 1.50V (you have some airflow on the ram, right?)
SOC 1.10V

left ur current settings, right the ones to try


if you don't have airflow just keep it on c16 if that's already stable. good luck.

GDM off stable on CL15
GDM On auto become 16
1T can be apply on GDM On but i use aida benchmark is not good than CL15 + 2T. I’ll try out ur setting when i get back home. thx ya

ye ofc, gdm can only operate with even numbers. I was just expecting to see your c15 setting in the screenshot

tried ur setting. need clear cmos...must be bad luck again getting bad stick

If you have Samsung B die kit. Watch your memory temps. Once it goes above 50C , memtest will spew errors everywhere.
If you have the guts , then increase vdimm to 1.5V. push for cl14 and dont use 2T CR. In bios , CR put Auto and enable Gear Down Mode.

Vsoc put 1.1V enough, i know that once you hit 1.15V and above here , it can start to spew errors .
Vddg iod 1.05V.

I think you can reduce your soc voltage to just 1.10v. This can cool down CPU a bit. SOC voltage only important for fclk stability.

Read up 🤣 thats what he was asked to set. So he done that.


You can try to raise tRFC to 280 n see if it posts.
You can use the safe boot button btw, no need to clear cmos.

Edit: @k!nex VDDG to 1.05V? poor IMC.
for B-Dies just keep between 0.95V & 1V. Try what suits your chip.

Vddg iod 1.05V is by default on my motherboard if i put FCLK at 1900Mhz. I have read that this voltage safe setting is not to go over 1.1V and it needs to be at least 40mV below Vsoc.

Auto != correct

Good boards will have no issue having it in the range I proposed. He does have a very good board. There are some bad ones where you can increase the range until 1.05V but that's just unnecessary stress and pointless to be done as long as the infinity fabric is stable.

if i stress the ram it will go above 50 and keep increase temp. if no stress it would stay below 50.
i’m using lianli dynamic and fully watercool.

it will not post if i use 1T for 3800mhz + cl 14

Oh, don't get me wrong btw, I'm not saying its the wrong voltage for you.
But usually when I test fclk stability I start with .95V and almost always get it stable below 1V.
If your IF doesn't run stable below that value ur fine to have it. But if it'd work on a lesser voltage it'd be a waste not to do so.

my radiator is blocking my button 😔

haha dynamic or dynamicxl?

dynamic only. i’m poor fag boss

looks ... colorful but ya very tricky one with bottom rad

is my voltage got problem ? i don’t really know what you guys talking those voltages @@ sorry ya

No problem per sē, we just pointed out you can lower SOC Voltage to 1.10V.
Possibly you can set VDDG to 0.95 and VDDP to 1.0V as well but that's not really a must.
Then some different opinions on VDDG (haven't even started with VDDP) but all irrelevant as long as your infinity fabric stable.
That's not what keeping you from booting CL14.

Just keep you old setting. Not like you're wasting much performance anyways.
1.45V will be nice, too. No need to bother too much about temperatures.
