DDR4 RAM Overclocking issue's binworthy BDIE ?

[Subsonicq]

Hi everyone, Ive been attempting to overclock the ram for whatever reason and not a single success, it may be that this kit just cant do it but lets try.

 

The RAM: GSKILL TRIDENT Z NEO / see bellow for Thaipoon data.

CPU: Ryzen 3700x overclocked to 4.4ghz @ 1.285v SOC 1.1v

MOBO: Asus ROG STRIX X570-F

 

So the ram loads the DOCP profile fine, DOCP or JEDEC profile if you push voltage passed 1.35v even up to 1.5v the system will post but windows BSODS with hardware crash is what the code transalates to.

I have altered the timings even just a little and it never passes memtest over a few hours, however JEDEC and DOCP pass no problem.

I have bumped up the FLCK and Infinity fabric (FLCK /2) and it doesnt pass memtest over a few hours but loads fine. And heres an odd one, if i reset everything to do with RAM to auto .... it doesnt post, go figure.

So, my thoughts are maybe that the sub timings that are always auto could be causing OC issues, RAM CALC for Ryzen doesnt help me one bit due to its touchy state, another could be the OHM settings ? really im not sure, i would like to give up but id rather come to understand why or what is causing the limit for interest sake, if i can get more out of the RAM thats great but if its not going to happen well its alright where it is then. Thanks everyone.

B-Die at 3600mhz is 16-16-16-36 1.35v.

 

I'm doubting the accuracy of this program.....

This is how i fell too, but the XMP profile does match the sticker so thats one thing right haha. if i put those timing in, im not even sure jumping the CMOS would get me out of trouble haha!

gskill's spd isnt always accurate, and thaiphoon burner or whatever program reads exactly what's there. theyre likely c-die which typically shows up as b-die with gskill's dimms. theres a thread about it on that german overclocking site, hardwareluxx i think? that being said i was able to get my 3200c16 kit (of what shows up as b-die but what is presumably c-die) to 3800c19 at 1.45v but you may not wanna go that high with voltage as we dont know much about c-die and 3800mhz wasnt stable on that mobo with any dimms anyways. 

 

setting all ram settings to auto never works afaik as there's too many variables to train. as it is, even with my confirmed b-die kit that was shit binned (3200c16 corsair v4.31) i couldnt get lower timings, only higher frequencies with timings bumped up to match. wouldnt make sense if you could eke much out of em, otherwise they wouldve been binned better lol.

This is true, i was in hope to maybe bump the frequency up a little and timing to match if it benchmarked better id keep it. i might try keeping at 1.35 and knocking frequency up and losser timing a tad. C-Die would explain why it crashes when you knock the volts up with no other changes.

 

Keep the ideas coming.

Buy a kit of actual 16gb 3600mhz B-Die and have a much better experience??

 

It won't go faster. 

Try 3200mhz CL16 / CL14 and see if you have better results.

Thanks, its a 32g kit. i think in the future at some point ill just buy two 16 kits as when i bought it i didnt know that 4 dimm kits werent the best. bit of a shame.

It's easier on the IMC if....

16GB and only 2 sticks.

 

Since your memory controller is good for 3200mhz, that's where you should aim your clocks with 32GB of memory (or lower with tighter timings)
