first of all it's displaying the memory clocks as 2.6GHz... WTF?

my model is factory overclocked to 430 core 1.3GHz memory i have in the past run at 495/1420 with no problems it refuses to let me overclock at all and if i use "detect optimal frequencies" it will set them but not keep the settings and for some reason changes my refresh rate

i only upgraded because day of defeat (not source) was giving some BSOD with nv4_disp.dll (and only DoD) and it was also giving some problems with black boxes being displayed instead of muzzle flashes... so far the black box issue is gone and i have not run into the BSOD yet

I use 91.47 with my 7800gs works great for pretty much everything.

The double clock frequency thing is normal. On my 6800GT it did the same thing.

Yeah the memory thing is normal. It's reporting your effective clock rate because it's DDR memory, I believe.

effective clock rate is the 1.3GHz

You sure about that? So the true clock rate is 650MHz? I don't care enough to google.

Clock rate on my OC'd 6800GT was 550 MHz, or 1.1 GHz DDR. But it reported 2.2 GHz which of course was quite wrong.

Hmm, that's wierd.

This problem is well known and has even been documented by nv in their release notes. You have two options for the foreseeable future:

1. Use any driver prior to 93.xx. 92.91 at nzone is the last working CoolBits driver.

2. Use Rivatuner for your overclocking and speed display needs.

you can use ATI Tool
