Those are some high voltages, are you on water?

I updated to 0703, and enabled P1.

Now my bandwidth is 8560 MB/s (read) but I had 9000 MB/s with BIOS 0508 (and P1 disabled).

I don't understand what's the problem and if it's better to have BIOS 0509 and more bandwidth or not.

Probably your RAM is running at default settings? in mines most of the time I upgrade BIOS I have to manually imput the timings or it will go to 1333mhz 9-9-9-24

No.

They are running at 1621MHz 7-6-6-25 2T.

I put them manually after upgrade.

Had you tried if you had more bandwidth before upgrading from 0508?


EDIT: A blue screen appeared, so I relaxed timings to 7-7-7-24 2T. Now I get a 9060 MB/s bandwidth.

In BIOS 0508 memory was working right at 7-6-6-25 2T with a 9000 MB/s bandwidth, I hope it is just a bug of newer bios and it will be fixed in the future.

Well anything after 0508 is totally unestable for me. The newer the BIOS, the worse it gets. However, memory bandwidth went from 88xx to 9100Mbs in Everest Benchmark.

Going to try 701 right now...

Yes, as per my sig! Which voltages do you think are high?
