Memory clock doesn't save in the BIOS

[flowzy]

Hey!

So I have a pretty oldish motherboard with AM3+ socket (this one) and I recently bought a 16GB Kingston memory (2 sticks)

As my motherboard doesn't support that high frequency, I lowered it in the BIOS to 1066MHz.

After I do that and press "Save & Exit", everything boots fine. But every time in shut down my PC and then turn it on again, it sets RAM's frequency back to 1866MHz.

Is there any way to fix that issue?

 

Thanks!

If it sets itself to 1866 Mhz, why are you lowering it to 1066? As long as CPUZ checks out with it and states that its 1866, it should be good to go.

 

EDIT: according to their website's memory support list, it supports memory up to 2200 Mhz, just that it downclocks to 1600. Last updated 2011, BIOS last updated 2013. Might have changed.

The thing is, that it doesn't boot then. It stucks with a black screen or with a message about overclocking.

And if I have 1866MHz, but MB supports 1333MHz+ only with overclocking, doesn't it generate more heat?

Hmm, then im not sure about that. Regarding the overclocking, since your RAM is rated at that frequency so it shouldnt overheat, but the MB might be supplying more voltage than it was rated to...

Turns out, that I just had to "Load fail-safe settings" in the BIOS and I could then boot with 1866MHz memory.

Thanks for your help!

Your MOBO allows 1600Mhz when downclocked from 1866. If you would read the memory support list for your MOBO you would see this. Now it could be how you are downclocking the memory, have you just changed the frequency or timings and voltage as well? Also can you save any OC profiles to the BIOS? < is one way to make you new frequency stay.

If I change the frequency, I can set timings and voltage to "Auto" and it automaticly lowers them.

And yes, I can save profiles to the BIOS. At least I saw that option.

Will see how 1866MHz will go. If it will crash from time to time, I will try to lower it again.

Thanks!
