AMD Turion X2 1.8ghz overclocked to 2.3ghz. How?

In CPU-Z's database, there is a Turion X2 TL-56 (1.8ghz) that has been overclocked to 2.3ghz! And that's the 90nm version (Taylor). There is also another that has been overclocked to 2.1ghz (90nm TL-56). I have the 65nm version which produces less heat and I'm running on a cooling pad aswell. From these results I'm thinking that overclocking to 2.0ghz should be achieveable and stable, but what program can I use?

 

I used clockgen to oc my 1.6GHz TX2 to 1.9GHz, and that was undervolted. If I would have kept the stock voltage, I could have gotten in to 2.0-2.1GHz easily.

 

Do you know why ClockGen has been taken down from CPUID's site? It just says it will be back soon.

Did overclocking the CPU initially cause crashes as you increased the speed? And did it make the laptop feel much faster?

 

What SW to use for OVerclocking laptop chips? ...i know it voids warranty but i ll manage without warranty.

 

Like I said, I overclocked my cpu while being undervolted (stock was 1.075 now is 0.950) so yeah I had some instability problems. But that's only because I undervolted.

 

adinu and a few other guys are the experts on this with AMD. ClockGen is how you do. I get my 1.6 Turion up to 1.9, more does not hold. Every chip has a different max so you have to test your's! Do not assume! Post back when you have more questions. Also the comment "over clocking" voids your warranty, this is SW based so unless you tell, not an issue.

 

i was just gonna ask how is anybody going to know if you overclocked the chip if u use software...until i read the down to the previous post.

not like changing the jumpers or anything.

is a bios able to record anything like that?

 

RMClock confirms my overclock, and so does the BIOS, cpuz and windows, so I think I'm fine right?

 

Anyone notice your RAM speeds up? kind of a bonus?

 

Yeah cuz you increase the system bus. It's also a bonus for gaming if you have an integrated card because that overclocks the gpu's ram clocks.

 

What PLL did you use for your AMD Turion X2?

I read a guide that basically said to keep guessing until you find one that gives the correct clock readings. With either 'ICS 950405' or 'ICS 951416' I get the same readings as CPU-Z, and they both seem to work fine, though 'ICS 950405' doesn't always change the clock speed. I also ticked 'Ignore GSB/PCI'.

I've gradually increased the clock speed to 1999.5mhz (using 10mhz increments) and my wPrime 32m score has gone from 43.35 to 38.814, which is the same as the TL-60s on the wPrime benchmark list. It also got 1237.561 seconds on the 1024m stability test and it seemed perfecty stable and no hotter than usual.

I'm intrigued; the memory controller on the TL-56 underclocks 667mhz DDR2 RAM to 600mhz (effective speed). When I increase the RAM speed from its actual speed of 300mhz back to 333.3mhz (667mhz effective) the clock speed is 1999.5mhz (clockgen overclocks the RAM with the CPU and FSB). It's like the TL-56 is a TL-60 (2ghz) that has been underclocked to 1.8ghz.

 

wow...i just love discussions on overclocking...

Another safety question: How can i reduce temperature when overclocking laptop? Notebook coolers good enough?

 

I have found my Zalman NC-1000 to be very effective. Normally when the laptop is sitting on a table you will get a build up of hot air under the base which rises through the laptop and heats it up and then when the fans draw heat from the vents at the base of the laptop, they are pulling warm air though the laptop. Using a good cooler stops the build up of heat and provides cool air to the fans that draw air from under the base of the laptop. It made a big difference to my laptop, now when gaming it is cooler than it was without the cooler when just being generally used for the internet/office work.

Just make sure you get a cooler that works with the direction of your fans in the laptop, so if your fans draw air from the base and push it out the side, a cooler that blows air up is best.

Aswell as the Zalman NC-1000, the Cool Master Notepal Infinite is supposed to be good ( NBR Review).
