AMD Kaveri A10-7850K Overclock Guide - Page 53

post #521 of 1332
Please don't consider that I'm full of it, I have my Kaveri A10-7850K at 4.78Ghz with 5 fan air cooling setup.
Using the ASRock Extreme 6+ it's also been possible to get my 1866Mhz Corsair Vengeance up to 2173Mhz @ 10, 11,10,34 & that's something that was not possible with my ASUS board previously.
I have been able to game on this OC well, only title I play is BF4 but experience is good thus far. Am keeping the GPU at 800Mhz as I don't experience any throttling using 800Mhz.

What voltage?

I still haven't done mine yet. Life is too busy.

I am currently using the C6 feature available on the ASRock FM2A88X Extreme 6+ but a good guide on the Voltage required would be 1.53750V for 4.6Ghz. As stated am using C6, while this method would lead to failure under load when gaming on my Llano overclock /ASUS board the ASRock board is proving to be a great overclocker using C6 with voltage changes reducing the temps enough to be manageable.
My maximum overclock on Llano & Kaveri was achieved using the same voltage & setup ran for 2 years without a problem. I'd consider if you need a voltage for 24/7 OC then 1.53750 or 1.53650 would suit. The power delivery on this ASRock board is superior to all I have used before hence why I am able to get the OC stable with C6 enabled and still get a game on. thumb.gif

Is the extreme 6 board better than the killer board when it comes to power delivery?

DannyDK am going on experience with products used myself. Have not had the FM2A88X+ Killer product & couldn't find detail of the power delivery on your board. The Extreme 6+ has the 8 + 2 Power Phase Design but am unsure if it was carried into into the Killer Series which has added features I don't have on the Extreme 6+

It has 4 + 2

That use of C6 will thus close down 2 cores to enable power saving from what I remember. You are likely only on 2 cores or possible 1 not 4 when running this configuration.

os2wiz,
Thanks for updating me on C6 as I never had a full understanding of it before. Gonna do some reading on it now.
Cheers

To anyone with a Kaveri 7850 pref running the onboard R7, does the RAM in aida64, the bios, or anything report what it is accurately? eg a 2133 kit as 2133. Without XMP enabled.

According to my bios my ram is running at 1866 'overclocked' as I manually set timings and speeds, the kit I bought is rated for 2133, and stock it runs at 1600. CPU-Z has it rated at 1600 (incorrect speed but correct part number), and aida64 extreme is telling me it's a 1600 kit. My nb speed is at 2 ghz.

I'm starting to wonder if there's a huge issue with the current bios across multiple manufacturers for Kaveri and it's handling of RAM as I've seen countless threads with this problem. Kaveri should be able to handle 2133 stock out of the box according to what I've read.

ASCI Blue,

Check your using CPUZ version 1.69 and hit the memory tab. My BCLK is set at 101 leaving my memory at 1086.7Mhz for a Dual Channel kit it doubles = 2173.4Mhz


Sure your Memory should be recorded correctly with this method, mine always has been.
regards
