I have been running clean and clear for some time now, but now seeing about 3% invalid (on AP) running 1MB+1AP. Could anyone give me advice on what I should be running?

GPU AMD Radeon R7 240
2 GB mem
6 CU
780 Mhz nominal clock
Over clocked at 900, but it only runs that 5 - 10% of the time it seems

Current config:

<app_config>

<app>
<name>setiathome_v7</name>
<cmdline>-sbs 256 -period_iterations_num 48</cmdline>
<gpu_versions>
<gpu_usage>0.4</gpu_usage>
<cpu_usage>0.4</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v7</name>
<cmdline>-unroll 6 -ffa_block 4096 -ffa_block_fetch 2048</cmdline>
<gpu_versions>
<gpu_usage>0.6</gpu_usage>
<cpu_usage>0.4</cpu_usage>
</gpu_versions>
</app>

</app_config>

Any ideas?
