I tried this feature out on my A10-5800K, Asrock FM2A55M-DGS, and 8GB of G-Skill Sniper 2133mhz sticks. The feature takes my A10 up to 4.2Ghz but kicks my ram down to 1333Mhz. Sup with that shizz? No beuno. :(
When I used AI suite for my Asus z77 v pro it downclocked my ram too. Regardless, I nuked that OC right away. I just wanted to see what it would do, and it oc'd my CPU way too high anyway. Manually overclocking is the best way. I'm not familiar with overclocking the A10 though. Hopefully someone who knows whats up with those can chime in.
Yeah I'm not that familiar with it either and I don't have the time to go in and do trial and error style OCing. I did see an article where some cat got this thing up to 7.2Ghz. So it can be OCed like a boss. LIKE A BOSS. I'll make a thread about it as soon as I can get a waterblock on this thing. The stock cooler is a$$.
I would recommend checking this video out. I believe somewhere in there they mention that 1866MHz memory is the highest frequency of memory the APU can use. So, I think that's your problem.
I've heard that too, but my memory is indeed running at 2133Mhz and the APU seems just fine with it. The issue is that when I overclock the APU it lowers my memory frequency down to 1333Mhz. This is of course just using the Asrock X-boost feature during boot. I have only played with the XMP profiles in the BIOS for a short while but the memory works just fine. I think this might be a short sight on Asrock's part. I will try clocking the memory down to 1866Mhz and then using X-boost and seeing if that makes any difference. Could be a voltage issue.
It will always drop the ram to 1333. When you use push OC they are trying to give you a "stable" OC, so they move the clock speed up and ram speed down in order to prevent BSOD... but its really just a gimmick. Do some reading OC yourself, you will feel and be alot better for it. Learn when voltage degreation becomes an issue and just stay a bit under the voltage.
If you are not a pro overclocker, no point in trying to be. Get a nice OC, and enjoy the fun of it.
I thought that might be the case but wasn't sure. It kind of defeats the purpose doesn't it lol. Which is better, faster APU and slower ram, or slower APU and faster ram? I might have to do some benchmarking next week and find out.
Are you using the APU for graphics? Ram speed matters alot then, if you are not and just gaming clock speed matters more.
Yes I am. I've been very impressed with this APU so far. If there's a way to overclock the APU and keep my ram frequency above 1866Mhz that would be ideal.
BIOS overclock... real overclocking.
Same thing just happened to me on my Asrock FM2A75 Pro4-M, A10-5800K and Corsair Vengeance 2133 (with 2133 in the xmp profile).
overclock the proper way with FSB, multiplier, and voltage. don't use a third party software
