Title: GA-990FXA-UD5 issues - Part II
Post by: absic on June 29, 2011, 07:03:38 pm
First off, apologies to anyone who has tried to post in the Original thread here:,5939.0.html as there seems to be an issue with posting some replies. Hopefully we will be able to resolve the problem quickly but, in the meantime, please continue here: Thanks absic.

Hi all, I just got this information from Gigabyte UK.

Since this CPU AMD 1090T X6 supports CPb function (AMD turbo core boost) when all cores run at full loading it does not reach the designated assigned Voltage Pb0. (due to CPb features). Note by absic:- this applies to all the multicore processors not just the 1090T

Using Super PI testing one core full loading test software and it can reach the designated Vcore Pb0.

We have tested Asus M5A99X EVO and has the same outcome under full loading.

For a better understanding of how AMD's Turbo Core works you might like to look at this post: which goes into the subject a little bit.
