Na grafiku vid popis som pustil OmniExtremeEdit a zistil som, ze do gpu 1.5V nepustim, aspon nie cez tento editor. Co sa stane, ak zmenim bios v nejakom inom editore tak, ze mu natvrdo nastavim 1.5V? Da sa to vobec?
On jiny editor neexistuje :wink: Jelikoz mas 5900XT tak mas uz jen jedinou moznost, v OEE si dej Tools a Hex view a poradne si precti tohle (ale uvidis, ze to neni zrovna jednoduche):
GPU VOLTS.
~~~~~~~~~~~~~~~
Closely located to the three speed tables, is another Table of seven 2 Bit values for controlling GPU Volts, structured as follows,
07 78 04 82 05 8C 06
The purpose of this table is to set the GPU volts during 2D, Throttling and 3D modes. In simple terms, the first two bit value represents the max number of table options, and the follow on three 4 bit words show the actual options that are set for this bios. However note that the first two bits of each 4 bit word is only an indicator, and has no functional purpose other than it indicates the volts expected (found by, converting to decimal/100). The last two bits of each 4 bit word are the important ones, because they set the GPU volts for the various modes of the card.
Using above example shows,
(hex 78.)/100 or 120/100 = 1.2 = 04 option.
(hex 82)/100 or 130/100 = 1.3 = 05 option.
(hex 8C)/100 or 140/100 = 1.4 = 06 option.
This shows that GPU volts in 2D as set by option 04 is 1.2V, and in Throttling mode as set by option 05 is 1.3V and finally 3D as set by option 06 is 1.4V. You can however interchange any of the 4 bit values, and thus set 2D GPU volts at 1.4V if desired.
There is a seventh option, indicated by the "07" at the start of the table, which is needed by a 5950u, where it sets the GPU volts at 1.5V in order that it can run at higher speeds. And when present is normally represented by "96 07" in the 3D position of the table. And, although not normally used in a 5900nu or 5900u bios, there is no reason why either of these can't have the GPU volts set to give the same 1.5v of a 5950u.
