I have a couple problems with my setup. One is just strange, and another one is super weird.
Was hoping kind folks in this thread could share their wisdom and experience on the matter.
I have a CH6 mobo + 2700(non X) CPU and ever since i got it(about 6 month ago), i couldn't get my system to work stable at 3200Mhz memory settings and above.
First, I`ve been using Corsair 3200 kit (Hynix AFR chips). And system just crushed after a minute or so after boot with 3200 setting. I tried XMP, manual, timing tweaking, memory voltage boost. Nothing works. As soon as I set 3200 MHz - system starts crushing. 3133 and below - and everything is super stable.
At first, I thought I just got unlucky with memory kit.
Few days ago, i decided to switch to HyperX Predator HX436C17PB3/8 (2 sticks). It`s a samsung B-die chips(K4A8G085WB-BCRC), high speed, mediocre timings and good price for a b-die.
The thing is, with these sticks problem remains the same. Anything above 3133 - unstable within minutes. Difference is, on Corsair kit - system hang completely. With these new - only application crushes.
No matter what timings I use, what voltage, CPU overclocked or not - it will not work above 3133.
For now, using memory calculator, I set everything 14, 14, 14, 30, 44 with 3133Mhz (1,36 volt) and everything works fine. but still. It should work above 3200? Right?
What could cause this? Really unlucky memory controller? Maybe faulty motherboard? Have any one experienced something like that?
I do want to switch to 3700x eventualy. But desided to wait a litle for more feedback and stable bios.
And on top of that, got a really weird one too.
These new stick I use, have issue i have never heard before and could not even google something similar.
Whenever I set CAS to 15 or 17(manual or XMP, does not matter), after reboot it always sets to +1. 16 and 18 accordingly.
It only behaves like that with 15 and 17. With 14, for example, or any other number, everything is set correctly.
Is it a bios bug? Right now I`m using 6903. Still waiting for something stable above that.
Thank you in advance for your comments and replys.
