OC troubles [Mobility 3450, ATITool, AMD GPU Clock Tool]

[kylezo]

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 :P

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.
:P

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!



PS: just trying to un-underclock here...nothing fancy...got a cooling pad and my machine is plugged in 95% of the time.

Those Omega Drivers are relatively old. I believe the latest ones are from December of 2007 (7.12). I read in the other thread about overclocking the HD3650 that they can overclock using modded 8.9 and 8.10 drivers from ATI. Perhaps you can try those and see what happens. Good luck.

Edit:

Forgot to mention earlier. Stick to AMD GPU Clock Tool for the overclocking, and only use ATItool for checking artifacts. If you use ATItool to OC, your computer it will crash (at least when I tried it on the HD3470).

Hmm, I have used ATI Tool succesfully to OC (or at least, get a reasonable 350/425 or so out of it, netting me like 15-20 more fps). Problem is, I have to set the original values to something crazy like 600/800 which then 'resets' to the 350/425 area.

I'll definitely try the modded 8.9 and 8.10 like you suggested. The only reason I am using Omega is because they are the only ones I have tried that allow me to change clocks at all.

Thanks for the tip!

Which version of AGCT are you using? (Mine only OCs with .7, not .9.8)

[kylezo]

Using .9.8....HM interesting :P I'll look for an earlier version. Thanks for the tip.

follow up=

I have been overclocking (or perhaps un-underclocking) using ATI Tool for quite a while now, with a very noticeable improvement in performance. The settings I am using are as follows:

I move the sliders to 600/800 or so, usually a little higher, and the values reset to 300/400. So it's either a 50/50 overclock (still 200/300 under default) or a 100/100 true overclock. I still don't know which, and haven't gotten any more information on this issue from any other forums since I started asking around. The overclock is stable.
