XFX 6870 won't underclock memory at idle

I've been having a problem with my 6870 lately. The memory stays clocked at the full 1050MHz at idle as opposed to the 300MHz it's supposed to drop down to. Core clock drops to 300MHz, but memory will stay clocked high and it causes the card to idle at almost 60C as opposed to 45C when the memory is downclocked. I can downclock the memory using ATI Tray Tools, but it's a pain to do this every time I restart. Any ideas? Thanks in advance.

Dual monitors?

Memory stays at 1050MHz when using more than one screen with a 6870.

Use a tool like GPU-Z to pull a copy of the video card's bios. Then, take a peek at the settings of that copy of the bios and see if the settings are set to maintain the same memory speed across all states. Then, if that's what's going on, just flash an updated bios with appropriate settings, either based on edits you've made or edits from XFX if they've released a fixed bios to take advantage of power saving by lowering memory speeds.
