Can't get 3600Mhz RAM to run stable at 3466Mhz - Crosshair VI Hero (WiFi ac)

Hello everyone!

 

I'm currently having a go at overclocking my machine and I'm struggling to get my RAM to stay stable when running at a clock speed below what it should.

 

I have:

Ryzen 1700 (OC'd to 3.9)

Crosshair VI Hero

GSkill Trident Z 3600 MHz RAM.

 

After reading about some people having issues getting Ryzen to play nice with 3600Mhz RAM I saw some people having success with 3466Mhz so decided to try the safer option and go for that. I took all of the details of my RAM and inputted the details from the DRAM caclulator and entered them in my BIOS, attempted to run Intel Burn Test and it passed 10, 50 and 100 runs on standard, but when I set it to maximum the machine freezes up after about 15-20 minutes.

 

It's not a temp CPU issue as checking Ryzen master shows it maxing at about 61.

 

I've also tested my CPU overclock on it's own and that is stable.

 

Any help would really be appreciated!

 

Thanks

chances are you either need more SOC voltage and risk degrading your IMC on the CPU and/or increased DRAM voltage.

Already have SOC at 1.1 and DRAM at 1.42 - didn't know how safe it would be to go over that/would it be worth it for the performance.

I don't know of anyone else that uses IBT to test RAM.  A lot of folks use TM5, memtest64, or other free memory testing software.  If IBT is freezing then something is wrong, but I wouldn't pin that on your RAM setup.

As far an im aware IBT uses RAM very heavily - especially in the higher stress tests! Although I'm happy to be corrected if I am wrong.

 

I am 99.9 percent sure my CPU overclock is ok - it's passed all the IBT tests on it's own as well as a few hours in Prime and OCCT(trying to be safe - ha)

 

Only fails once I apply the change in RAM settings. Although I will give one of those pieces of software a try to see if they show any problems!

3600mhz is a lot for first gen Ryzen to handle.  Even at 3200mhz i could only get 3.8ghz on a 1700x stable, i wouldn't be surprised if 3600mhz or even 3466 is just too much to handle. Ryzen 2 can handle these speeds better but still with drawbacks, I had to downclock to 2800mhz to reach 4.2ghz all core on a 2700x.  You could try a higher SOC but hitting 1.2v you start to get in a fairly high risk area on Ryzen 1. Definitely keep the ram at the OC voltage.

 

If you decide to downclock you can go through the timings and try to optimize the latency at the speed you choose, it does take some time though. I think anything between 2800mhz to 3200mhz would be a good spot depending on CPU quality, clock goal, and workload planned. If its gaming no big deal at 2800mhz, Ryzen does do better in gaming at higher memory frequency do to it also increasing InfinityFabric speed, though i think after a point it becomes diminishing returns for the CPU clock you sacrifice and stability.

 

For stress testing IBT is okay, also try a round of OCCT large FFT or ASUS RealBench stress test and benchmark.  They all have advantages, Realbench is more real world and you can have it load all your ram with 7zip to test parts of your IMC, OCCT is good all around for memory and core at large FFTs, any smaller is just extreme thermal testing.

1.1v on the SOC is to low most likely. To get my 4x8 3200mhz Flare X kit stable on my Crosshair VI Hero (non wifi), I have to run my SOC at 1.175v with LLC set to high. You are safe to go up to 1.2v 24/7 usage on SOC voltages.

3466 is already pretty lucky for a first gen ryzen, just lower the timings.

Thank you for the help everyone! doen't look like I am going to get 3466 working so I am giving 3400 a go, just going to work my way back and see what I can get working best.

Hello guys, just an update looking for some advice.

 

Got my RAM to finally work at 3333Mhz with my CPU at 3.9Ghz.

 

Got my CPU at 1.35 volts and my RAM at 1.38.

 

Managed to pass every benchmark (OCCT for 3 hours normal, 2 hours on Linpack, Maxmimum on 50 cycles of intel burn test, 8 hours of real bench and had no errors at all in any benchmarks i've been doing, as well as about 40 minutes playing Battlefield 1) except Prime 95 that fails with a rounding error after about 3 hours. Im running a blend test which I think is more likely to be the ram that fails?

 

I was considering either doing a Memtest or upping my RAM volts to 1.4 and trying again.

 

Was wondering if this was needed or if it is likely that it could be a false positive - my RAM is still not running to it's actual speed, and the CPU overclock(and my temps are very stable)

 

No idea what to do next.

Honestly I don't put much faith in Prime95.  Memtest64 is a great test for memory stability and error checking.  Sounds like you're pretty much stable thought depending on what you're going to be doing

not to resurrect this thread but set the soc voltage to 1.175v-1.2v then set the ram voltage to 1.45v. use the dram calc settings for your ram. set the cpu volts to 1.425v and test again. these volts are completely safe. some memory kits are xmp certified for 1.45v. the soc volts are safe upto 1.25v for daily usage.

 

if these voltages wont get it stable than you need to start backing down clocks.

 

good luck.
