Hi
Most likley to do with drivers; make sure you have CAPS installed
From your screen shot I would say 507Mhz core 500Mhz Mem is showing as you have some apps open in windows, close all apps other than CCC and the core and mem should drop, from what I understand your 3D core of 790 and mem of 915 will only be available to both VPU's when games are run in full screen. if you run a game in a window and looked at GPUz you will only have activated one core
open catalyst control centre/performance/AMD Overdrive (leave this option open)
Try this first
open CCC
go to Performance/AMD OverDrive
next
go to Presets/add Preset -Fill in Name e.g: Default vid OC /Location remove all ticks & then Save
NEXT
Goto Control Panel\ folder options/view - select Show hidden files and folders
NEXT
open Computer/ explore C:\Users\*Your user profile*\AppData\Local\ATI\ACE\Profiles/you should see your newly created Default vid OC.xml
NEXT
Highlite - Default vid OC.xml - press right hand mouse button - select edit
you will see - Feature name="CoreClockTarget"
Example-
<Property name="Want_0" value="15700" />
<Property name="Want_1" value="55000" />
<Property name="Want_2" value="79000" />
raise the Want_0 value from 15700 to 40000
this will adjust your core clock once you are in the windows enviroment and allows you to continue using AMD's ULps settings.
open CCC go to presets and select Default vid OC; this will apply the new settings
nb: as you have a 4870x2 you should see two entries to adjust for the coreclock targets (do this for Master & Slave)
Note: if you reinstall drivers at any point you will have to set option up again
.........................................................................
**make a system resore point before attempting to edit the windows registry**
however; you could try this
disable ULps power saving settings, this will enable both VPU's / GPU's, this allows you to monitor both VPU's in CCC
open regedit
navigate to the following key
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ (you will see lots of folders we need the thirteenth (13) folder down from "Class" - open the folder and you will see 0000
look for "EnableUlps" and change its data value to 0 (zero)
repeat this process in ControlSet002
reboot your PC
nb: only ever flash bios as a last resort *NB* ATI 4870x2 if you realy have to DO NOT FORGET to backup Both bios's Master & Slave
atb (all the best)
Law-II
