Massive drop in 3D Mark score...

[ChrisD.]

Done a run yesterday evening, Q6600 @ 3805, GTX @ 650/1005

Today I dropped the Q6600 down to 3650 as it wasn't really stable before and upped the GTX slightly to 652/1030. Items in bold are todays run. Same drivers.

What's not right?

 

[Greebo]

You haven't accidently changed anything like aa or af?

All your graphics settings the same as before?

 

[ChrisD.]

Yes mate. All the same, not touched anything really apart from slightly lower vcore.

 

[Sir Random]

Maybe the GTX is throttling back to stock speeds. Use Rivatuner to monitor clock speeds during the 3DMark test.

 

[ChrisD.]

I think I know what it might be. Bear with me while I try something and run another test.

 

[ChrisD.]

Solved. I enables CME Enhanced Halt Start in accordance with one of the guides.

Now that it's been disabled I just scored 15111.
