Hardware I'm workin with:

HP EliteBook 6930p with ATI Radeon Mobility HD 3450 @ 256/512/somethin like that...as many diff. results as I have sys info programs


Installed the latest Omega drivers (modded with Mobility Modder).

I am ~able~ to change the clock rates now (kinda)...with both ATI Tool and AMD GPU Clock Tool (NOT with ATI Tray Tools at all). I have been checking with GPU-Z but I am kinda confused...

GPU-Z shows me, main pane:

GPU Clock: 550 (sometimes this is 500)
Default Clock: 500

Memory: 700
Default: 700

Sensor pane shows 249/346.

In AMD GPU Clock Tool, current clock is shown as 499.50/693.

Ok, so I don't know who to believe. If I add 21/17, values in GPU-Z should show 270/364. Instead, it shows 253/351.

Also, I set 510/710 in AGCT, and now the values show 506/702.

I don't get why the numbers are all different.

Add 50 to each in AGCT, I get 546/738 (-3/-5 from what I put in) and 273/369 in GPU-Z (-26/-27 from how much I added in AGCT). In the main display it shows 550/743.

I add 100 to GPU in AGCT, I get +95 in AGCT, +50 in GPU-Z main pane, +42 in sensor pane.

But wait, there's more!

ATI Tool!

I ran 'find max mem' for about 20 min and arond 435MHz, my screen started cycling through colors and grayscale.
Ok.


Had to hard power down (hold power for ~8 sec). Not really willing to run any other tests.. =S

So my clocks show in ATI Tool as 249/346. Good so far. I change Core to 349, click set, and it changes to 173/171. Not good. But, the good part is, in GPU-Z, sensor shows 173/171. At least there's some consistancy! But, GPU-Z main pane shows 349/346, which is what i put into ATITool in the first place. *** mate.

I add 50 to each in ATI Tool, I get 148/198 in both ATI Tool sliders and in GPU-Z sensor pane. But I get 299/396 in GPU-Z main pane, which is what I put in. Hit default, and it resets the sliders and the sensor pane to 249/346, and the main pane to 500/700.

I input -40 to each in ATI Tool (209/306) and the sliders/sensor pane show 102/153. Main pane shows 209/306.

Anyways..can anyone help me? Am I missing something? what's the deal here?

Thanks!

The lower clocks are the clocks in 2D power saving mode, the higher clocks are the clocks under load in 3D mode most likely.

AMD GPU Clock Tool is right on with the (3D) clocks.

just go to bios and oc it there.

I don't quite understand, I am seeing 2 different figures at the same time for 'current clock' in different programs, plus, one time I tried to downclock in ATI Tool by like 50MHz, to around 190 and it dropped me to like 90 MHz and my machine freaked out and froze up. Why would the sliders move down instead of up instantly? even when I am running a game or something. I'll try some more experimenting, like with WoW running.

This card doesn't support bios dumping...I guess I could flash it, but do you know someone with a hacked Mobility 3450 bios?

Thanks for the input guys!



edit: OK, WoW in window, GPU-Z shows 500/700 front pane, 249/346 sensor pane (normal). ~25 fps in WoW. I raise slider in ATI Tool to like 358/400, and it downclocks me to like 170/200 or so. I get 9fps in wow. front pane in GPU-Z shows 358/400, sensor shows 170/200 (as does ATI Tool). I raise the slider to 621/688, it downclocks me back to 310/342 (sensor and ATI Tool). Front pane shows 621/688, I get ~35-40 fps in wow. Are you saying I am clocked to 621/688, and the sensor/ATI Tool only shows my 2d clock speeds?

edit again: OK, so this is more wierd stuff. I raised the sliders up until the FINAL effect was 320/400. I saved it as a new profile in ATI Tools and it showed as "new (320.0 / 400.0)". I load the profile, and now it shows me @ 158/198.
