Overclocking RAM over it's MAX Frequency

Hello guys. Thank you all for answering (:

By the way, I've set it to 3200MHz and ran PassMark MemTest 86, did 4 passes and there were 0 errors. BUT, it didn't say 3200MHz but 2988MHz even tho I set it to 3200. So I guess it clocks back to it's max frequency? In CPU-Z it shows around 1590.. I guess you multiple that with 2 and you get your RAM's Frequency.. But I guess CPU-Z is lying since in MemTest86 it showed 2988MHz, right? I've set the frequency to 3066MHz, I guess there's no point of setting 3200 even tho it boots and works, it's not working at 3200. Correct me if I'm wrong.

I have a 2x8GB kit of 3000MHz rated G.Skill (f4-3000c15d-16gvkb). I've tightened the timings from the stock 15-16-16-35 to 14-14-15-35, but needed 1.4v to be stable. I've also overclocked it to 3200 with 16-16-16-37 at 1.4v. I've spent the past several days running Memtest86 to verify stability with different timings. I tend to use the method mentioned in Comprehensive Memory Overclocking Guide. The Stress Testing (Validating Stability) section describes how to choose only test #6 with 10 runs. It usually takes about 20 minutes to do all 10 runs. I've also used the Custom Prime95 settings shown and run for 8 hours.

 

Memtest86 will show the kits rated speed, regardless of what you've set in the bios. Just ignore that. CPU-Z is correct. If you can complete 10 passes of test #6 without any errors, then you're ram is stable. Sometimes it's not as easy as simply raising the frequency. It may boot, but it won't be stable.

Hello guys. It's me again, being annoying as usual with all these questions lately.

I tried looking up what I needed but couldn't find any topic related to the exact thing I need an answer to.

I have Corsair Vengeance LPX 3000MHz 2x4GB Kit. It has printed 3000Mhz on it and these latency numbers:
16-17-17-35 and voltage of 1.36v.


What I was wondering is that I've been running my RAM at 2933MHz, then I tried overclocking to 3066MHz and then to 3200MHz. And it all works. System boots, I run stress test in Prime95 for like 5-10 minutes and everything works fine. 
My sistem is (in short):
R7 1700 at 3.5Ghz 1.300v

Asus B350-F Gaming

EVGA 500W 80%+ Silver

GTX1050TI OC

 

What can happen if I let my RAM run at 3066 or even 3200MHz even tho it's 3000MHz RAM kit? Is it safe? Can it fry my MoBo or any part of it? Is it shortening my RAM's lifespan?
The only reason I'm doing this is because I've seen everyone saying how Ryzen loves high frequency RAM. And to be honest I like trying stuff myself and learning from it. Just don't want to fry something in the process.
Thank you all in advance.


Best Regards,
Alex

its safe, might be unstabile unless you raise the voltage though and if you are still on auto timings those are bound to go to shit. use memtest 86 to test if its fine, id to at least 4 passes and if they are all error free it should be good

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

no it won't hurt your mobo or shorten your rams life, don't feed it too much voltage or you might fry something. and yeah, memtest to test your ram for stability because instability tends to strike at the worst time and make for a bad day

Some ram chips really hit the silicon lottery, like my 2133Mhz G.Skill chips that allowed an OC to 2800 before becoming unstable. Just watch your voltages.

Thank you guys. You have all been very helpful (:
I will test to see which frequency is both max and stable.
Thank you very much for explaining it to me and telling me how to set it, test it and to know how to be sure if it's stable. Short but detailed help. If the topic don't get closed I'll let you guys know which frequency is possible on my RAM.

Best Regards,

Alex

OK. I've tested my ram. It can work, stable, at 3200MHz. I've let it run for more than 20 hours. I didn't mess with the timings, i've let them on stock 15-17-17-35 at 1.36v

I saw, from amd, that we should keep the resistance between 60 and 90 ohms. Anyone can confirm that? It's on auto for me.

My RAM can go up to 3600MHz, even tho it's a 3000MHz RAM. But there isnt much of a difference. But from 2933 to 3200, difference is quite noticeable. In gaming i get up to 15-20fps increase. Some games it's around 10fps increase. I need a better cooling for my CPU. Im using stock ryzen 7 1700 cooler, wraith spire. It's ok, and looks really nice.. but definitely not good enough for that CPU.

Thank you everyone.
Best Regards,

Alex
