Downclocking With a Twist

Well, after spending the entire weekend working on it, I've made some headway into downclocking on the 9262 with dual 8800 cards.

The first is: if you set the RMDynamicSLIAllowed DWORD entry in your registry to "1", then you no longer have to restart your computer to switch between turning SLI on and off. Make sure to change every instance of this DWORD (ctrl+f is your friend).

My cards always boot up into throttle mode (275/301) clocks. When I switch SLI on or off, they go up to their full clocks and stay there.....until the next restart. On any computer restart, they go back to 275/301. If I flip the SLI on or off, they go up to full clocks and stay there. So essentially, before playing any games, I have to flip SLI on and off. This is really annoying.

Believe me when I say I spent an entire 3 days of my life trying to fix this downclocking on restart problem. I've tried the 175.75, 175.80, 177.92, and 175.32 drivers, all with no luck. I tried uninstalling drivers and running DriverSweeper, DriverCleaner, and CCleaner, in and out of safe mode, even installing drivers in safe mode, even using Have Disk. Nothing will stop my computer from restarting windows with downclocked cards. I've tried different system BIOS and different video BIOS. I'm using Vista Home Premium. At the end of 4 months, I still consider my Sager a big paperweight.

My guess is that a clean install of the OS _may_ fix the issue (as it almost always does), but that's not an option for me, and also there's no guarantee all of that time spent reinstalling everything won't end up with the same problem.

I have definitely tried all of the known registry tweaks (such as the 3333->2222 tweak, setting the PowerMizer entries, and the RMPowerSupplyCapacity entries; I do have my system set to High Performance mode in Vista Power Options).

Any tips would be welcome.

 

Is there a reason to downclock except to save battery?
Excuse me if thats a stupid question.

 

Heat is another reason

 

I had this same problem just a few days before my laptop "died", I have the Sager NP9262 just like you, with dual 8800m GTX's, re-installing the Operating System did not solve anything and none of the registry / Riva Tuner / BIOS Flash fixes seemed to fix the throttling problem, and a few days after that, the laptop refused to boot up (No POST, Caps - Scroll - Num Locks status lights were blinking at the same time just before the laptop shut itself off).

I do not know if a motherboard failure could be connected to this, but it seems like that it is a hardware-wise problem and not a software issue, since no drivers, nor fixes or BIOS flashes fixed the problem for me, so now I am about to send my laptop to Sager for repairs.

I am sorry to hear that you are having this issue, too. :/

Update: Now I recall that I have had the downclocking issue since I bought my laptop, I just had not noticed it because I did not use to turn the laptop off often, and since I did not play any of the newer games, I did not notice framedrops or stuttering.

 

Wow, that's pretty rough. I'm really sorry you had your laptop completely die. Hopefully Sager can fix it up for you. Let me know if it still downclocks when you get it back from them. If it doesn't, then maybe I should send mine in for repairs too...

 

Thanks. I will let you know the results once I get the laptop back, and create a thread on the whole issue, since it seems that this is not a so-isolated issue anymore (6 people in the past 2 months have had this issue, counting ourselves).
