Something weird going on

I have an M17x r1 running 4870's in CrossFireX and they run just fine. I have been working on 3 PC's this week all that have ATi GPU's, a 4350, 4870 and 5970. I downloaded the latest driver from ATi, 10.12 and each of the PC's have been tested with mild OC's and working just fine so I decided to update the driver on my M17x since it did not have OC ability in CCC.

After the update it still did not have OC in CCC so I bootd into Safe Mode and removed the drivers, ran DriverSweeper and removed all vestiges of ATi and CCC then rebooted and extracted the mobility update of 10.12 and still no OC ability. Is this right?

 

I've never seen the ability to OC on a mobile platform from within CCC. Were those other PCs desktops, or laptops? That's the reason that folks use all of the external OC programs that you see around here in the forums. That would be awesome to be able to OC from within CCC, because I am not a fan of flashing my cards just to see if I can manage another benchmark run with 5 more Mhz. I know you can OC within Windows with a couple of programs, but I prefer to flash.

 

To be honest I was able to OC when I had the 2 nVidia 280m's in SLi but never noticed if I had the ability, or not, prior to this with the ATi 4870's, the other PC's were indeed desktops. I do know if I change the CPU clock in setfsb from BIOS my scores ramp up with the change as the GPU score does as well. I thought I had somehow lost the ability to OC and perhaps maybe I never had it.

 

Overdrive is available under Catalyst Mobility 10.12 or 10.12 Preview CCC2 driver packages, at least in single card configurations. The clock range shown is for a 5850, not a 5870.

​

 

I'm not using the 10.12, but I certainly will be soon if it lets you OC from within Windows!

 

Hmm, I did not notice overdrive when I updated to the newer CC.

May have to check into that tonight

 

That is the CCC I expected to see but not what I have! Are you using the one from AMD/ATi or from DELL?

 

In the M15x, we found that Overdrive would install cleanly if the vbios had never been modified and reflashed. If the vbios was previously reflashed, it is necessary to:

(a) reflash the video card with the original, unmodified vbios file. It is not enough to simply return a modified vbios to the stock settings (remember those warnings in RBE about the loaded vbios file not including OD settings?)

(b) run Driver Sweeper after uninstalling the existing driver set through Control Panal/Uninstall a Program. When installing drivers while using a modified vbios, a registry flag is set that prevents OD from being included. That registry flag persists and prevents the installation of OD until removed. Driver Sweeper cleans it out.

Once OD is installed, you can modify the vbios to increase the upper clock limits and the voltage (at least within limits). On the M15x at least, increasing the base clocks in the vbios results in OD disappearing from CCC, but it will reappear when the base clocks are reset to stock levels.

Edit: I'm using a mobility modded ATI set: Download Mobility 10.12 CCC2 Preview Win7 [email protected].

 

Yeah, I don't have the option for OC. I'm not flashing back to the old VBIOS. Not for a million bucks.

 

LOL. When I say old, I mean an original of the current most recent version issued by Dell, not some ancient vbios. Why would someone who does all of his overclocking by reflashing the vbios hesitate to reflash with the foundation version of that vbios? On the other hand, I certainly do not wish to encourage something you are not comfortable doing.

 

Well it's now the correct version but still no option to OC. I purchased these and never once flashed the vbios, don't know how, guess I'll stick with it as is. + rep to both of you.

 

How many VBIOS have Dell offered since the initial one that remedied the sleep mode/can't run on battery problems? That's the only one I've ever flashed. I'm comfortable doing it. I've done it probably a dozen times in the last week. I just don't want to go back to the VBIOS that goes into the endless BSOD loop if you ever drop to battery. I hated that.

 

Well checked last night and I don't have the oc'ing option in the new cc.

Not sure if I want to reinstall the drivers since they seem to be working.

D.

 

I do not have it either, tried 3 versions of CCC (including the one posted earlier here, the previed one), and maybe 10 different drivers.

I have the normal stuff like Powerplay, some 3D settings etc, but no overclocking options.
I predict when you reinstall drivers, or install other ones, you still won't have the options.
I have been at this for almost a week and I can't figure it out (i'm running stock videocards and rest of the system, never overclocked yet, no messing with biosses etc).
