SU9600 overclocking?

I'm curious to know if whether the SU9600 can be overclocked. I have no need for it right now but wonder what this processor is capable of and down the line it may prove useful. It can max out at 1.8ghz anyway so that is good. I was wondering though what headroom this processor has.

A forum member checked what the PLL was this motherboard for the Sony TT and i believe that it is this ICS9LPRS369EKLFT.

I've looked at setfsb and cannot see a setting for the above code.

I'm not that experienced with setfsb so may be i'm missing something.

So what do you think can it be done or not or would it involve opening up the TT and performing some hack which i'm not prepared to do.

Thanks

 

Alienware M11x changes the BSEL CPU signals from 200->266 for their 1.3->1.73Ghz overclock on the SU4100/SU7300 CPUs. Appears Intel may not have implemented lowest-multiplier lockout on those CPUs. If you want to try that overclock suggest reading this and this post. Involved would be adding a pulldown resistor to the FSLb PLL pin.

 

Thank you nando4. I think if it involved soldering of any sort i would send it away to have the work done if i wanted to go ahead with this. Is there any implications at all on battery life?

 

Suggest review Moral_Hazard's PLL pinmod thread to confirm if your PLL is TME-locked by checking the TME_Readback flag. If so, then would need soldering to either do the TME-unlock or FSLx+BSEL overclock mod.

TME-unlock would need software such as setfsb or the grub2 bootloader oc to program the PLL. If your PLL isn't supported, you could use say the support ICS9LPRS365 PLL in setfsb, and alter config byte 13 and 14 to change the FSB in the Diagnosis window. The configuration registers tend to be the same for the same family of PLLs.

The FSLx+BSEL PLL pinmod would take your SU9600-1.6 to 2.13Ghz at the highest multiplier. Problem there is that's a significant overclock with perhaps the CPU not having enough voltage to do. Would advise checking if you can disable speedstep in the bios to force lowest multiplier then use rmclock to control voltage/multipliers up to a stable point before contemplating that overclock.

Any overclocking would result in a minor degradation of battery life due to northbridge/CPU/graphics all running at a higher frequency.

 

Thanks again nando4, you've been very helpful.

 

I am sorry for digging to an old post.
My TT290 is running SU9400 and I also want to upgrade the CPU.
I have looked at Intel Processor Specs and found an interesting information.
All S Series CPU have exactly same package specifications:
TJ: 105
Package Size: 22x22mm
Die Size: 107 mm2
Transistors: 410 million
Package: BGA956
Lithography: 45nm
VID: 1.05-1.15V
All 3 SU, SL and SP have exactly same spec above.
SU9600 1.6GHz has 800MHz FSB, 3MB L2 and 10W TDP Max
SL9600 2.13GHz has 1066MHz FSB, 6MB L2 and 17W TDP Max
SP9600 2.53GHz has 1006MHz FSB, 6MB L2 and 25W TDP Max
The interesting thing I want to talk here is between SU and SL, both have the same die size, transistor amount, but different in L2 caches which means Intel has turned off half of L2 cache on SL/SP, slower FSB to make SU.
What I am thinking here is SU can be overclocked to run at 2.53GHz Max at 1066MHz FSB.
I don't know if there is anyone can modify CPU FSB and Multiplier to get max out while it is still running stable. Thermal system can be mod later.

 

See FSLx and FSLx+BSEL mod in http://forum.notebookreview.com/har...verclocking-methods-examples.html#post4998927, noting:

* the BSEL mod can be done on SU4100/SU7300 CPUs without it going into lowest multiplier lockout

* a 2510P user got access to the BGA U7xxx CPU pins via the underside of the system here so it might be able to be tested using a trace created using a conductive pen.

* iif you can hack the bios to disable EIST-lock bit, then could do a 1.6->1.8Ghz dualIDA overclock using Throttlestop.
