My System Specs

Default A8 3500m Showing its abilities after I have had it for over a year

Have had this laptop for a while now, but never really thought about OCing my laptop. Specs are below in my signature, but its a llano a8 3500m that I just upgraded to 8gb ram. Once I did that I started looking into if there was much headroom on these CPUs. What I found was that it is full of headroom. I went in trying to keep temps under 70 deg, but in the end settled with a 500mhz OC on all 4 cores and the exact same temps (tops out at 62 in prime95). Everything tested for short runs in prime 95 to check for stability (about 5 min per frequency...I know I should do more, but I was time compressed). I am positive there is more room for improving this, but I am happy for the time being. Just take a look at how much I was able to lower voltages at a given frequency below:


0.2v lower at 800mhz. max freq on 4 cores up 500mhz @ 0.05 lower voltage. Kept the boost clock the same (2.4ghz on a single core), but lower the voltage substantially. I could turn all the voltage drops into improved performance, but I was after a good daily use OC. I also put in a lower freq P0 state @600mhz and LOW voltage. It should help extend battery life when not requiring much CPU...I will keep an eye on it though to see if during general use its able to maintain that 600mhz, or if it is increasing all the time.

One thing I do not like about overclocking my A6 (laptop) is that I have to turn off AHCI to reach a decent OC.

Reviving another one of my old thread. Running the OC I have above I didn't have any issues with AHCI. Just put an SSD in and even at stock clocks I was having issues with freezing/blue screens. Changing from amd sata driver to the MS one seems to have fixed it. Made other changes to settings as well, as some people online said they had issues until they turned "PCI express link power state management " off...no power saving (this setting is automatically turned off if you go to high performance vice balanced power saving. Not sure exactly which solved the issue, but it seems to be resolved so I am happy.

Thought I would update this just in case someone ever has a similar issue. Now running the same OC with the SSD with AHCI.
