dv6646us TL-58 7150m Overclocked!

Thread Starter 
Using nVidia System Tools since it is the 630m chipset, I overclocked the FSB from 200 mhz to 242 mhz (voltages had to be manually increased to 1.175v using CrystalCPUID multiplier management). The RAM timings had no effect in changing so it is best to leave the same. I then overclocked the GPU from 425 mhz to 560 mhz using PowerStrip. Overall in benchmarks my system is 20% faster....20% more CPU and RAM with 8% more FPS benchmarks. Heat is still pretty good with the stock cooling and an ambient air temp of 88 deg. F. My beast now went from 1.9 ghz to a screaming 2.3 ghz. After all this overclocking I can now play STALKER in "high" detail instead of previously being only able to play it in "low".

So even with an HP computer it is possible to overclock the hell out of it and have no real draw-backs except an acceptable amount of heat. These numbers are the MAXIMUM that one can go without introducing instability.

Cool, would u be able to share some prt-screen shots?

cheers ...

Over Clock Went Perfect Thanks To You. It Actually Runs Cooler Than When I Used The Recomended XP Drivers From The Forums. What Graphics Driver Did U End Up Using? I Tried The Latest One With A Modified .ini But Didnt Run Perfect. Thanks

Yeah I had to use the 174.something mobileforce drivers because the 175 ones were artifacting- even with no overclocking. Even the 174 drivers have issues in certain applications like STALKER....in which case I just boot into Vista where the 175 drivers work fine.

Hi Dr. Owned, I used to be able to use CrystalCPUID to change my voltages from 1.100V to 1.175V but I can't anymore. Do you know why? I have a HP Pavillion dv2745SE. I can go up to 1.150 but not 1.175. Strange.

The maximum voltage of 1.175V is locked by the CPU/motherboard and can not be changed. You can actually run your voltage as low as .75V I believe (via manual modification of the crystalcpuid config file) but slightly higher is required to run in a stable overclocked configuration.
I believe it is voltage that is the limiting factor on how high the system can be ovelclocked. Since I made my original post, I've had to scale the FSB down to 238 mhz to increase stability to "24/7".

Thanks for the quick reply. Lowest 4.0x FID is 0.850V, but max is 1.150V at 10.0x FID. I have a AMD Turion 64 X2 TL-60 at 2.0GHz, what do you think I can do with that? I'll try editing the config file and see what happens too.

Your cpu is identical to mine with the exception of a 10x multiplier as opposed to a 9.5x multiplier for me. So i'd lay money that you could get up to 238 mhz FSB as well. To find the ceiling of FSB overclocking, just keep bumping it up until you get freezing/rebooting and then back it down. For example, if you set the FSB to the maximum in System Tools of 250 mhz you likely won't even be able to close the window without getting a crash.

Don't bother editing the config since .85V is really the minimum that should be fed in when overclocked.

I just tried 238 MHz FSB and it works fine, but would I have to change my voltage there, or is it fine at the normal 10.0x (1.100V) and undervolted 4.0x to 0.8500v? At 242 FSB it'll start freezing up, and the 238 FSB you gave me is pretty stable.

And GPU Clock memory is 0 MHz - now trying 791 MHz, and GPU Core clock is at 425 MHz default, so I can overclock it up to 535 Mhz I think without any artifacts, any higher would get artifacts. I'm using 180.84 balance inf modified by Dox at LV2Go.

I would run @10x 1.175V just to increase stability. Bear in mind that the extra voltage will increase heat. In the end you might need to tone your FSB down more than me because of your higher multiplier. But 2.4 ghz isn't bad for a laptop

The GPU memory clock is 0 mhz because the 7150m doesn't have any dedicated GPU memory...it just leeches off your system's regular RAM. Thus overclocking the FSB overclocks the ram speed as well which also increases gfx rates. Don't worry though, the difference in performance between 535 mhz and 560 mhz is very small....it's the shared RAM that is the performance limit.

The final result of my overclocks was that my system across the board benched 20% higher.

Interesting! Sorry too tired to even type correctly , CrystalCPUID multiplier management won't allow me to set it to 1.175 for some reason, only 1.150. I am now running 238 FSB (and 535 GPU Core and 333 GPU Mem) with 10.0x on 1.100v default.

But I do agree that shared RAM is the culprit in all integrated GPUs. Running at 238MHz FSB and the GPU Core set at 535 MHz, there is a little improvement, pretty good if you ask me.

Powerstrip gives me some problems, sometimes the system won't start up correctly, and I had to uninstall it through Safe mode. I just use System tools and edit the profile manually.

Not sure what the HT Multiplier is but the NVIDIA system tools reports that it is 4x.

FSBMHZ=200 to 238
AGPMHZ=2500 to 3000
GPUCOREMHZ0= 425 to 535
GPUMEMMHZ0= 0 to 333

Do you get artifacts at GPU Core of 560 MHz? In some games it's noticeable with all of these white artifacts, and in some games the artifacts aren't that noticeable. Do you know what I can get with 1.150v? I suppose 238 FSB is still the best - even at 1.175v from what you're telling me.

Also you said you had a 1.8GHz processor then overclocked it to 2.3GHz with 242MHz FSB, but doesn't that mean you went up to 2.42GHz and not 2.3GHz?

Actually instead of 1.100V as default I found out that 1.500V was default... I think. Temps when running the game are about 80-85c and CPU is 75c.

Yes, powerstrip is a little buggy but its not too bad. HT Link, from my understanding, is how fast the cores on the cpu will talk to each other but it is stuck at 4x as well.

No, I initially ran my gpu up to 590 "stable" (no crashes) but I got a ton of artifacts. At 560 I don't see any.

I have a 1.9 ghz cpu (200 FSB x 9.5 multiplier) that I got up to 238 FSB = 2.26 ghz.

Guys try this driver out http://www.laptopvideo2go.com/forum/...howtopic=22225 I just installed it and i can play EQ2 with 2x the options i could B4. My system runs so much cooler. Tell me if u get similiar resaults

I am using that driver, but are you using the balanced, performance, or quality inf? What driver did you use before that?

I dont think you should have an issue getting up that high. I have a 1.6 ghz version of the turion running @ 2 ghz.

I can go up to 242 MHz, interesting though that RMClock reports that my highest clock is 1.5v, and under that is 1.125v. 238 MHz is actually stable. In some games I see major artifacts with 560 and some games I don't strangely. I must test this out more. Plus it seems that Dox driver has now gone 1.1. Funny though, if I set it to 242 MHz FSB it goes to 243 and if I go to 239 it goes to 238 for example.

I just keep going with mine. I dont know why you guys are having to turn up the voltage...

My goforce 6150 is @ 540 mhz w00t stable @ 72 degrees C with a custom cooling pad

Interesting! I just checked again and 238 seem to be quite stable and the GPU core as well should be 530 since 535 has artifacts, and memory at 666.

I used Balanced. Dr owned what tempiture program do u use cause speedFan is giving me numbers that are scary. It says its running way way too hot but to the touch the entire system seems a lot cooler.
