1950X Memory Overclocking

[Toasted Waffles]

I've struggled to get my ram any higher than 2133. I'm running the Asus Zenith Extreme non Alpha on the newest Bios. Of course running a 1950x with Corsair Vengence 128g rated for 3000mhz. What do I need to do to get this somewhat close. I've tried the DOCP and it runs but in any game the computer crashes. I'm running the overclock on my cpu at 4ghz with 1.3 volts and no problems and stable. When I add in the memory everything kinda explodes. Help My frames are suffering.

• DDR4 3000 (PC4 24000)
• Timing 16-18-18-36

128GB is hell for the IMC on the 1950X. My B-Die kit was able to reach 2933. If your kit isn't B-Die, idk how much you're going to get out of it.

why are you running Threadripper for gaming

Was gonna say, 1st gen TR has a lot of the same memory issues the consumer (Ryzen) Zen chips had IIRC, B-Die plays a lot nicer with them. IDK about memory compatibility with 2nd gen TR (Zen+) but I assume it was greatly improved, same as the consumer Zen+ chips.

It improved for sure, just not when you take 8 DIMMs into account. It's just a bit much if you're aiming for memory frequency.

I running renders for 3d mapping and other stuff.

Should I just slowly try to raise it until its unstable. Start with the correct timming then go from there?

See how far you get with only 4 DIMMs installed first. That will give you an idea of if you might get any further with 8.

I can get my 3200 kit to 3466 when I drop down to 64GB.

 I don't wanna push more than 4 sticks on my X99 rig because the IMC can bork out when pushed too hard, same with every other platform with an IMC I think. Pushing higher capacity DIMMS for a lower overall DIMM count is easier on the IMC and allows for higher clocks. It's especially a common practice for guys trying to push super thicc OCs on their RAM, but on something like 1000 series TR that already has RAM issues it'd be even more important.

Manually tweaking the RAM is probably the best way to go about that, there's likely guides for that (I've only ever done memory overclocking on X58 and that's a whole different thing due to the dependance on BLCK overclocking).

Yeah. I'd be running a 64GB quad channel 3600 G.Skill kit if I didn't regularly consume 80GB+ of RAM when busy. I played around with it for a bit when I had it in house and gaming was a treat (on the 2950X) but I don't really game so it wasn't something that was worth stepping "down" to.

I've started pushing 2800mhz on all 8 dimms with the correct timing. Everything seems stable I've been running cpu and memory stress test all day and seems stable with no hiccups. Surprisingly I've had to continue my overclock on my cpu to get everything to communicate properly. Now I'm running so far stable 4.2ghz at 1.356 volts and memory at 2800mhz. Thank you guys so much.

Awesome! Yeah, my kit is @ 2933 so you're not far off at all.

4.2 on a 1950X is  quite the feat! If I remember correctly, I was @ 4.175 max.

I'm pushing to get to at least 4.4 but we will see.
