Overclocking

Matthew Parr · Feb 1, 2009

yes i do have a HP, I dont want an extreme computer just want a bit more from it! it was £500 brand new.Also how would i go about overclocking it, thanks for the replys.
EDIT: Just found this http://www.hardwarecanucks.com/foru...chmarking/8862-hp-pavilions-overclocking.html it may help:/
The spec there:

ok, well keep this in mind: the higher you try to clock anything, the more voltage you must give it. the more voltage you give it, the more heat it creates. the heating part won't be an issue for you since (according to the people in your link) you are unable to raise voltages. in that case, you may be able to squeeze out .3-.5GHz maybe, but that's about it.

after increasing the clock, be sure to run prime95 for a while (hours) to make sure it's stable.

Without a new motherboard you will not be able to overclock the cpu well.

What graphics card do you have?

Thats true, if you had a custom build pc, you would have a great overclocking potential with the Q6600. I have mine running at 3.6 GHZ since the day i have it.

The only possibilty to overclock seems to your graphics card, i think you have an NVIDIA 8600 GT Turbocache with 512 MB memory.

I am not sure this card uses shared memory, hp's specs are not clear on that.

You can download atitool http://www.techpowerup.com/atitool/.
You can run the find the max core and mem option there and it will try to find the highest possible settings.

If the tool is ready write down the values and be sure you go about 5% under that values for safety.

Do some benchmarks before and after the overclock to see the results. Use coolbits to enable overclocking features in your drivers. http://downloads.guru3d.com/ForceWare-Coolbits-2.0-download-815.html

As far as I am aware the Ati Tools driver does not work properly in vista (might just be vista 64). Thus for me it shows no clocks. Even when it did, finding the max clocks in ati tools was never a particularly successful way to overclock it from personal experience.

I recommend rivatuner to overclock that gpu.

You just need to up the core about 5-10mhz at a time and test it for a while in game. Once it crashes for produces artifacts then lower the overclock a bit. Do the same for the memory.

Also use the rivatuner hardware monitor to check temps. Probably don't want it to go above 80-90C whilst in game.

Does coolbits even work with the newest control panel? I thought it only worked on the old one.

yes i do have 8600GT, right ok il have a go at it! Thanks guys

EDIT: can u see the levels whilst in game?

Matthew Parr · Feb 1, 2009

What do i do from here, settings wise ?

Marcel Hulsbergen · Feb 1, 2009

Run fraps while you play then you see the fps, and check if you won a lot by overclocking. If it only gave you 2 till 5 fps more i should not even overclock it, but when i do it on my card it gives me 20 fps more.

Before you tweak it, first try to find the maximal values with atitool.

Then you can add some values to overclocking.

Yes but for Atitool you need to know yor PLL dont you and i dont know what mine is! ?
Also how do i know the temperature ?

Damian Henderson · Feb 1, 2009

All I can say is good luck.

I would recommend bumping the fan speed up in riva tuner - obviously you won't want it so high that it is annoyingly loud, so try and set it as high as you can before it gets too noisy.

Matthew Parr · Feb 1, 2009

yep i +10ghz and the frame rate went up by 10-15 with default fan!

Thats a good result for a start, yes as mentioned by others power up the fan a bit. If you see artifarcs during driving close the game and lower the settings. Use a tool to measure the temps after racing.

Matthew Parr · Feb 1, 2009

OK ive put it up a tad more along with the fan its now 20+ original! ive put it up 25 by the way!
EDIT: What program should i use to measure the temperature ?

Matt Alpeter · Feb 1, 2009

i'm pretty sure there's a monitor built into rivatuner. in any case, you'll know when it gets too hot when your graphics turn pretty colors.

you can also use speedfan, which is pretty popular.

edit: found a nifty pic off the interweb, here you go:
