I'm using a 2710p with an U7600 and DDR 6400 Ram and could really use the performance increase (1,4 GHZ seems to be no problem...).

So, is there any way I can help you?

A hardmod will get you an overclock but void your warranty. Simply apply a pull-up resistor on the PLL FSLb pin as shown here to go from 133->166Mhz FSB. SU4100/SU7300 M11x and Asus UL30VT overclocks the PLL the same way which means that likely the U7600 can be BSEL overclocked without being locked to the lowest multiplier. Can also disable TME while at it.

So basically, according to this post, I have to sever the contact of pin 11 to the mainboard and have to ground it via a 10k resistor?
Is this enough to overclock, as it seems to disable TME, I guess I can overclock the PC using SetFSB?
If so, is there any disadvantage over hard-overclocking to 166MHZ?

- setfsb was written for the 2510P's ics9lprs355 which is TME-locked. The 2710P has the same PLL but in the square package which setfsb doesn't work for So to get software overclocking working you'd need to apply the tme_unlock hardmod AND setfsb may require an update. You might be able to overclock by selecting a similar PLL in setfsb's list, eg: ics9lprs365??

- based on M11x/UL30VT overclocks, the ULV CPUs don't appear to be multiplier locked when BSEL mod is applied. Meaning then if you *don't* severe the FSLb pin you are applying a BSEL mod. If it works then the rest of the chipset (RAM, video card, northbridge) is all setup correctly as if a 166Mhz FSB CPU was installed. A very clean way of overclocking requiring no further compensations for timings than expected (eg: RAM SPDtable modification).

- For most flexibility could apply the tme-unlock and FSLb+BSEL mod. If the FSLb+BSEL mod worked, then could still go higher by using setfsb overclocking. If the FSLb+BSEL mod didn't work then you'd have setfsb overclocking to fall back on.

- Numerous reports show a U7600 CPU in 2510P can be easily overclocked to 1.5Ghz (166Mhz FSB) on stock voltage levels. Just need a pioneer to show how it's done on a 2710P.

Would there be a way to contact you more synchronously?
Like ICQ, MSN, ... ?

Bump!

Just wondering if you have made any progress on the overclocking...

Overclocking the 2710P - update

Standard warning: The steps below will void your warranty and could permanently damage your system if performed incorrectly. Please do not attempt the solder methods if you don't know what a multilayer systemboard.

The 2710P schematic, relevant snippets extracted below, makes it very easy to understand what is involved to overclock the 2710P. Method 1 has the advantage of being able to overclock to the point of instability in 0.3 Mhz increments. It is feasible too to combine both. Method 2 bringing the system to 166Mhz FSB, then using method 1 to overclock further if the system is capable.

Method 1: disable TME to allow setfsb software overclocking. [ relevant to U7xxx or L7xxx CPUs ]

Three different ways of doing this with the first requiring NO warranty voiding soldering on the systemboard if done right. You'll know when TME is disabled when setfsb diagnosis window shows the TME_READBACK flag status on register 9 bit6 has changed from 1 to 0, meaning can do software overclocking. Here's a screenshot showing where to look for the TME_READBACK status.

1. [untested] Jumper the pin2 to your GND pin1 on your debug port (spare unconnected 24-pin socket) to get the PCI2_TME pin to be logic 0. See the debug port layout here. Best done by attaching a 1k strong pull down resistor between those pins to ensure you don't short anything. Tested and did not work here.

2. Lift one of resistor R279's legs will disconnect 3.3V from the circuit, so that PCI2_TME will now see a logic 0. That means TME mode is disabled and therefore allow setfsb software overclocking. The resistor to disconnect is shown in YELLOW here.

Method 2: Set PLL to run at 166Mhz [relevant only to U7xxx CPUs ]

Just lift a leg from R197 to disconnect the PLL from the circuit, then route it to a 3.3V point at R195. sendig a logic 1 to the FSB pin, setting the PLL to run at 166Mhz. So a U7600-1.2 will now run at 1.5Ghz. The resistors are shown in here.

* EXTRA: CAS=5 in the 266Mhz SPDtable RAM entry for higher levels of overclocking[/b]

I found on my U7600-1.2 (133Mhz FSB) 2510P sees ~177Mhz FSB to be the cut-off point where the RAM timings start causing system instability. The way to correct this is to increase CAS from 4 to 5 against the 266Mhz SPDtable entry. That can be done using Thaiphoon Burner as shown here or with SpdTool.

Method 3: Set PLL to run at 200Mhz [ relevant only to U7xxx CPUs ]

More details about this are in the 2510P 200Mhz_bclk link. This will run a u7500/u7600/u7700 at 200x6 instead of 133x8/x9/x10 for faster RAM and X3100.

Just lift a leg from R829 and R834 will disconnect those parts of the circuit and send a logic 0 to the FSA and logic 1 to FSB, setting the PLL to run at 200Mhz. So a U7600-1.2 will now run at 200x6. The resistors to disconnect are shown here.

Softmod instead: dual-IDA bios mod

This is not a hardmod in the sense that a modded bios flash is involved instead and use of Throttlestop software. See http://forum.notebookreview.com/hp-b...ml#post6654683 . This may be preferred by those that do not want to void their warranty. Eg gains to be had:

U7600-1.2@x9 -> 1.33@x10
U7700-1.33@x10 ->1.46@x11
L7500-1.6@x8 -> 1.8@x9
L7700-1.8@x9 -> 2.0@x10

Conclusion

Combining method 1 OR 2 AND the dual-IDA bios mod would give the maximum overclockability possible.

I think if I had to do one mod, this would be it, provided there's easy access to the R279 resistor.

Could I use grub2-setfsb to get it working on Linux?

EXTRA: CAS=5 in the 266Mhz SPDtable RAM entry for higher levels of overclocking

Is there any Linux tool that would allow that?

Could you please maybe identify based on these photos where the marked resistors are?, that's it, if you know where to look for them.

Thx!

The resistors will be near your ics9lprs355 PLL, location as shown in RED in the picture to the right. Keep in mind that setfsb's ics9lprs355 support was written for the 2510P which unusually allows it to be overclocked even with TME enabled but will not do the same for the 2710P. Only difference is the 2510P has a rectangular ics9lprs355, the 2710P has a square one. That means you'll only know if the ics9lprs355 in setfsb will work with your TME-unlocked PLL. If not then you may need to email the author of setfsb to get support for a TME-unlocked ics9lprs355.

Once setfsb supports your variant of the ics9lprs355 then it is very easy to just update the grub2-setfsb's ics9lprs355.c as explained here to overclock your system to whatever level you wish.

You'll need to do your own research RE: Linux tool to write RAM spdtable. You could just remove your RAM modules and write to them on a friend's WinXP/Vista/7 system using Thaiphoon Burner.

when i try to install a chipset or video driver, a message "your computer does not meet the minimum hardware requirements" comes out.

why? how can i bypass this?

[nando4]

UPDATE. You have an unconnected 24-pin debug port near the fan controller. Above I've explained that that jumpering the debug port's pin2 and pin1 (GND) will disable TME mode.
