Corsair CMD16GX4M4B3400C16 (Samsung)

post #1 of 11
Thread Starter 
Started testing my first set of Samsung based DDR4, and these things are mystical unicorns :yepp:





First test is max freq, all four modules easily boot up and validate here with a mere 1.25v :shocked:



Second best module @ 1.35v




Best module @ 1.35v




Grabbing a bite to eat and then will post up some performance based benches (XTPoooo, GKBench3, GPUPi etc. . .)

Nice! Thank you for posting your results! Is it possible to share a screenshot from Thaiphoon Burner software to examine SPD technical details?

I don't have Thaiphoon Burner sorry frown.gif Also not sure if it works with DDR4 yet.

What do you want to know about SPD details?

RW Everything should be able to read out the hex values of the SPD

636cc of fury, it can access SPD EEPROM of DDR4 DIMMs since the beginning of 2014.

CorsairJake, I just want to make sure Corsair hides SDRAM Manufacturer ID within SPD registers as usual.

You mean do we identify which SDRam is being used in the SPD whether Hynix, Samsung, etc?
post #7 of 11
Yes, Jake. That is just I would like to know. SPD Bytes [0x15E] and [0x15F]. Also it would be great if Corsair would program DRAM Stepping - Byte [0x160]. This would help me identify the full part marking of SDRAM chips. TB is already capable of doing that for Kingston, G.SKILL, Micron, Hynix and Samsung DDR4 modules.

sooooo much more left in the tank, these things will shine when Skylake arrives as the full potential will be unlocked. X99 IMC is the main hindrance in high frequency clocks and it is very hard to find a chip that can run > 4000Mhz on air but that would be considered a killer IMC on Haswell-E.
