Evga 8800 Gts Memory Speed Locked! Will Not Change From 792!

Evga 8800 Gts Memory Speed Locked! Will Not Change From 792! <~ FOUND A FIX

Ok, for a while there I thought I was runnin 621/900 but it turns out rivatuner is showing me that my memory is running at 792 no matter what I do. I've reset my drivers, uninstall all overclocking programs and reinstalled them, rebooted from rivatuner instead of doing "detect now" after enabling overclocking. Nothing I do changes the clocks.

Whats wierd is when I change my clocks in ATITool, every other program except rivatuner shows the clocks I set. nvidia's monitoring program shows it, ATITool shows it, and even rivatuner's own slider bar in the overclocking page shows it. It simply isn't showing up in riva tuner's sensor monitor.

I've considered it could be rivatuner not showing the correct memory clock, but 1250Mhz on the memory in ATITool with zero artifacts and stock cooling is BS.

Has anyone ever heard of an 8800GTS's memory clocks not budging?

UPDATE (I fixed it):

I'm running dual monitors. When I disabled secondary display and set memory clocks, the clocks take. Then I enable my secondary monitor again and the memory clocks stick.

Running 621/1026 with 18.7k in 3dmark05!I hope this helps.

What version of Riva are you using?
my Evga 8800GTS and riva final version works just fine.

I'm using Riva Final as well.

I was thinking of using a bios editor, but that seems too risky. I just don't understand what would make the memory not budge.

BTW - I got the evga card that was 380 bucks with clocks at 500/800. You think it was the cheaper 640mb for a reason?

Evga is great.no problems so far.
in what frequency you raise the mem and it stays at 792?

any. no matter what frequency i set rivatuner shows 792. even when i try to downclock.

Hi

I have the same issue with my EVGA 8800 GTS Superclocked. Factory frequencies should be 576 Core, 1350 Shaders and 850 Memory. Rivatuner reports 576/1350 and 837 (!).

No matter what I do with the memory clock slider, I can't change the memory speed. However, I'm able to change the core speed (and the shaders speed also change automatically (seen with Rivatuner log)).

Hey good news, I found a fix. I'm running dual monitors. When I disabled secondary display and set memory clocks, the clocks take. Then I enable my secondary monitor again and the memory clocks stick.

Great! It works here as well!

I had two monitors plugged, but only one was activated in the windows display settings, however in the nvidia display settings they were set in clone mode. By changing it to single display I'm now able to change the memory clock!

The problem is that the "multiple display wizard" which ran automatically the first time didn't offer the single display option so I picked the closest one to my need which was clone mode.

Thank you!

I just had exactly the same issue on an ASus 8800gts 320MB. Setting display to single instead of clone solved it. Odd bug it be.
