X470 Taichi: mem frequency locked with Samsung OEM

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a X470 Taichi Ultimate on my testbench and can't clock Samsung OEM
 sticks with anything else than standard frequency.
Whenever I raise or 
lower memory frequency the Taichi won't post. It just sits there, spins 
the fans but doesn't begin memory training. Even the reset button is unresponsive. I gotta clear CMOS and switch off the PSU to make it 
bootable again.
This behaviour is the same with all Samsung OEM modules I own. Single Rank B-die 
and Dual Rank & SR C-die. They all have in common that there is no XMP 
profile present on these modules.

I can change the timings but not memory frequency.

ASRock X470 Taichi Ultimate

BIOS 1.50

Ryzen 1700

Any suggestions?

EDIT:
WARNING: On all or at least some X470 Taichi Ultimate motherboards DDR4 modules without an XMP profile can not be overclocked.
To
 make non-XMP DIMMs overclockable, an XMP profile has to be added to the
 DIMM's SPD and flashed to their EEPROM. This is risky and can damage your
 hardware!

	are those that ECC 2133mhz 1.2v without any heatsink rams? maybe raising voltage could help, but ull need some heatsink first before u start overclock anyway u did forgot to mention part number for your ram(s)

	Thanks for the reply kerberos_20! These sticks are all standard Samsung OEM, non-ECC, non registered and without XMP profiles. What I intended to use on this board are 2x16GB DR C-die (M378A2K43CB1-CRC). But they are locked on their standard frequency just as M378A1K43CB2-CRC and M378A1K43BB2-CRC are. It doesn't matter if I put anything in place (vDIMM, vSOC, procODT, RZQ dividers and so on) - the Taichi won't post. Not even if I lower the clock multiplier to DDR4-1866 or anything else. It's not the memory training that fails. The system doesn't even start up. So no memory training, no post, just total unresponsiveness. Why would I need heatsinks? On my C6H I can run those C-die @3466-16-19-19-1T @1.365v and the sticks barely get warm.

	did u check with infrared camera? :P anyway if that doesnt work in any way outside of spd settings (even lower frequency) which is kinda odd u may want to add some dummy xmp profile to it in linux (windows wont let u do that, linux is very friendly :-) ) spd rom can be accessed from smbus with reserved adresses 0x50 - 0x57

	I did not and the OEMs also don't come with temp sensors, but they are 100% stable and don't even need extra air cooling @3466. Those ICs are made for high frequencies and low voltages. They lack a bit in the timing department though. Heatspreader are overrated anyways. I thought about removing the heatspreaders of a 4x8GB Kit once, because the sticks are so tight to each other, that the heat can hardly dissapate. This is even more so on the Taichi Ultimate. The slots are so close to each other that there is only 1mm of space between the modules. Removing the heatspreaders would certainly help with temps there. Are you sure, that I can program the SPD of those sticks with an XMP Profile? I believe the paid version of Thaiphoon Burner let's you reprogram SPDs in Windows. I'll dig around and see if I can find some information on the matter.

	sure u can, spd rom is big enough these days well thaiphoon may be more user friendly than linux way, but in linux is it for free and whats more inmportant, if u brick your ram (bad spd flash) u can still reflash it later as grub allows u to block bad ram from being accessed by OS, so easy to fix later in case something bad happen

	These are great advices kerberos. I would not have thought about programming an XMP profile for these sticks. Many thanks! Since I am a total noob to either programming and Linux as well, you don't happen to have a tutorial at hand that could guide me through the process?

	not at all, i found that by accident when i flashed edid to one of my rams on notebook xD tho tutorials on how to flash edid under linux are there plenty and its basicaly the same stuff just that edid uses bytes 0-127 on 0x50 adress while ddr3/4 dimms have 256 byte spd flash device on 0x50-0x57 adresses (different i2c ofc) bytes 0-175 are for SPD bytes 176-185 Global Parameters for Intel Extreme Memory used across all profiles bytes 186-218 XMP profile 1 bytes 218-255 XMP profile 2 http://www.softnology.biz/pdf/Intel_XMP_Spec_Rev1.1.pdf here u can get info on each byte

	just sounds like a failed overclock to me increase or decrease blck by 1 it will change mem freq it will boot
