does this fix micro-shutter?
Hmm, I will tell my friend about this, but I doubt it will help him, since he just got the parts and doesn't know anything what they do lol

It's dated for October 2008... does this mean most people have it installed already?
wait wut, I bet it was a silent update via Windows Update when the update was published

I'm not sure. I think some hotfixes have to be installed manually.

Yeah some hotfixes have to be installed manually. I doubt this be lumped into the critical or recommened category since it applies to a very small percentage of people in which case it likely wouldn't ever even show up in the update center.

Might be in the hardware optional section.
Has anyone tried it? If it works, then MS didn't include it in an automatic update.
What is Active State Power Management (ASPM) which is causing the conflict?
When my other 4870 comes today I'm going to try this and see if it does anything.

Is this it? There might still be a BIOS option that overrides it though.

Followed the overly complicated links at MS, downloaded & extracted the files & was told update doesn't apply to my system. There are 2 Hotfixes v2 & v3; neither applied. Incidently, had to use IE as the site wouldn't let me select an x64 dl in firefox.

Here's a handy rar for anyone who wants it:

Microsoft has issued a hotfix which may be a possible answer to your performance woes if you own an ATI HD4870Ã-2 or HD3870Ã-2 card. According to Microsoft this issue happens according to the following scenario

  • You have a computer that is running Windows Server 2008 or Windows Vista Service Pack 1.
  • The computer is equipped with Peripheral Component Interconnect (PCI) Express Interface slots.
  • Active State Power Management (ASPM) is enabled in the computer's BIOS setup.
  • The computer is installed with ATI HD3870Ã-2, ATI HD4870Ã-2 hardware, or other hardware that has a PLX Technology Inc. PEX 8647-AB PCI Express switch.
The system may show low graphics performance, and occasionally the system or certain applications may respond slowly or may not respond at all.
unless im mistaken that pretty much means it ONLY applies to those running the x2 cards and not individual cards in crossfire right?
