Try HWMonitor.

As another update I had to dial down the FSB to 227 mhz in order to get more 24/7 stability. Otherwise any high I would usually end up with a complete freeze up every other day or so, even under idle load. I did manage to undervolt at the same time to squeeze out a little bit cooler temperatures while maintaining stability. I found that increasing the voltage really had no effect on stability, so I decided to go a few notches below the factory defaults until I got crashes. Settled on something like .75V low throttle voltage and 1.00V high throttle voltage. Roughly 15% lower voltage and 15% higher clock speeds than stock.

The GPU i settled for 555 mhz, but I really don't see any performance gains from it in 3d full screen games. I see small gains for flash videos and the like @ 210 mhz 2d settings. Also there's still a huge risk of system crashes when the overclock is being applied by Powerstrip.

If anyone is interested I'd be happy to post my CrystalCPUID config file with my multiplier management and voltage settings. And of course I use CCPU to replace the AMD driver for power management.

how to overclock dv6646us?

Hi,
I have a dv6646us hp laptop with a AMD Turion 64 X2 Mobile Technology TL-58 processor and would like to overclock it from 1.9Ghz to 2.3GHz like dr/owned did but I do not know how to overclock/change the voltage. Can someone tell me how I can do this to my laptop or can use the remote desktop connection to show me? Any help would be appreciated.
Thanks.

You need nvidia system tools 6.03 (higher versions don't work): http://www.nvidia.com/object/nvidia_...ools_6.03.html

Right click desktop -> Nvidia control panel -> Performance Menu - > Increase FSB to 238 mhz (any higher will crash) -> Close -> Say yes to apply on startup.

Hi Shaythong. Its my 1st time trying to overclock a lappie. My specs are exactly the same with yours. In one of your post, u mention increasing the AGP from 2500 to 3000. Where can i find that option. I have msi afterburner and crystalcpuid installed. Would also appriciate if you could post the latest full modification you made. Thanks lots

Now that I look at it, it looks like AGP clock rate is no longer available (in Sys Tools 6.03). Either way, turning it up didn't make any difference at all in benchmarks (for my dv6646 tl-58 1.9 ghz).

I tried overclocking my GPU at another frequency other then the factory specs but keep getting an error stating : Changes that we made were invalid and would not be applied. Any ideas?

I'm running Windows 7 Pro, MSDN and my GPU temp seemed to soared off the chart at 78 Degrees during rest and up to 100 during gaming. Compared to vista which runs at 60 something to 80 something during games. Anyone experincing the same thing

Com specs:
Compaq Presario v3828AU, AMD Turion TL-60, 2.0Ghz, 3GB DDR

System Tools can't overclock the GPU. You have to use Powerstrip: http://www.entechtaiwan.com/ps.htm

Overclocking your gpu will only have tiny benifits (ie don't go higher than a 10% overclock cause the gpu speed isn't the limiting factor...it's the shared memory speed). You can go as high as 25% overclock but your benchmarks will still be the same as +10%. If you have the 7150m you'd do best to increase the 2d clock speed from 100 mhz to 150 mhz though. I find that 100 mhz just doesn't cut the mustard in a lot of scenarios. 3d speed go to about 500 mhz.

Oh and if you're thinking about using System Tools to tweak your ram settings...don't bother. I tried tightening everything up to the max and it made no difference. It's really the CAS tweaking that makes the biggest difference (and the FSB overclock auto overclocks the ram mhz)...but CAS is locked.

Thanks lots. When i clocked my processor at higher than 215 mhz i seemed to get minor squarish lumps of pixels. (not actually artifacts). Anyway, my GPU ran at nearly 100degrees yesterday nite while just playing warcraft III (with coolerpad), is it still ok to overclock my GPU?

Yup, i have d 7150m

Ok final results are processor at 230mhz, Gpu at 442 mhz (3D) at 445 some minor artifacts begin appearing on Furmark stability test , 120mhz(2D). Performance incresed by 12%, temperature stabalise at max 92 Degrees during gaming

Thanks for your help dr/owned. without it, this would have taken me ages to accomplish. This site rocks!

Temps that high on the gpu are definitely not normal. I don't think i've ever seen mine go higher than about 70 C under full load. I do hope you regularly blow out your fan/heatsink assembly with compressed air. I found in mine that tons of little micro dust particles would stick to the copper (or whatever metal) fins and the fan would be caked. Blowing the whole underside out (dust came out from every gap) made a 5C difference is cpu temps and the fan didn't have to kick on as long.

Congrats on the overclock. Now you can play with CrystalCPUID to manually set up multiplier throttling and voltage based on load (I can send you my config if you want it) and also setup other System Tools profiles for when you're on battery. Oh and let me know if you ever get total system freeze ups where the screen completely artifacts and you have to hard reboot....I've been having the problem for a while now even when I'm not overclocked. Still not even sure *which* component is causing that problem...my guess is GPU though or some sort of software/driver incompatibility problem (since Vista was the default OS and I use XP).

Now that u mention it, I did encounter such situation a few times since my overclock. I think it has something to do with the overclocking process itself. Chips are made to run in binary system, that applies to their speed too. In other words, try to stay away from odd numbers when u overclock (eg 213mhz). Instead keep to 2,4,6,8 and 10 if possible (210mhz). Another probability may be overclocking the RAM itself. Not much info on that tho'. Anyway, my comp's seems to be quite stable now.

I've also tried blowing away the dust. But the odd thing is i use to run my GPU at a stable 57 degrees at rest on Vista. This problem only arises the moment I installed Win 7. I updated my BIOS and it seems to help a little but still could not achieve my previous temp. Maybe i'll try to search out for alternative open source drivers for my GPU

RAM I agree is probably the culprit...going from 666 mhz to nearly 800 would put a strain on even desktop kits...let alone the cheapo samsung set in there right now. Whole-screen graphics freeze-n-distort would be explained by the shared memory holding the image getting trashed.

Your gpu problem indeed is probably caused by driver issues. I was never able to get > 180 series working for me without bsods in XP, so I just stick with the 179 series from nvidia and manually install them via device manager.

Did you use GPU-z to find your temp or nvidia system monitor? I'm thinking that perhaps one or the other is misreporting the temperature cause 90 C would almost certainly start triggering fail-safe thermal shutdown of the chip. (Right now gpuz is telling me its at 57 C @ 100 mhz...78 F ambient room temp cpu @ 114 F idle)

I'm using Everest engineer's edition. Reading may be wrong but placing my finger over the ventilation hole sure dun lie. It burns

I'm also running 179.64

Can we summarize all into one post please.
I mean like
Driver: _____
Forceware: _____
Powerstrip ver: ____
CrystalCPUID settings(if you could upload the settings):_____
And last how to change the settings if you could because some may not know how to use it or dont even know anything(but again thats just if you want).
And a screeny bout the results.

This is totally either the drivers or powermizer sticking to max 3d mode all the time and not throttling correctly.
Dr owned said it mates.
Btw the ram wouldn't be a big deal, the bios should just simply adjust its timings and run it at 666mhz...if this is a laptop. Dells for sure do this, asus I'd bet 90% likely too. Unless the chipset supports a higher fsb...but that wouldn't make much sense to be running everything at 800 with ram at 666.

As per above screenies are welcome and explain things better.
