Guide: 6910P/6710B/6510B overclocking

6910P and 6710B/6510B overclocking [PLL=ICS9LPRS355BGLF]

Standard warning: The steps below will void your warranty and could permanently damage your system if performed incorrectly. Do not attempt any of the methods involving soldering if you do not understand what a multilayer systemboard is.

Surprisingly no 6910p/6710B/6510B lounge exists, so I'll create a new thread.

Try ICS9LPRS355BGLF in setfsb first!!

Before trying any of the pinmods below, the 6910P/6710B/6510B schematics indicate the ICS9LPRS355BGLF PLL is installed. This is the same as in 2510P, which has been successfully overclocked using setfsb [Freeware version] without requiring any PLL pinmods. Please try setfsb first and report your results.

If successful then can disregard method 1 below and advise the setfsb author that that ICS9LPRS355BGLF works with the 6910P/6710B/6510B as well. If not, then consider the methods below that use the 6910P schematic or 6710B/6510B schematic snippets to understand how to overclock these systems.

Method 1 has the advantage of being able to overclock to the point of instability in 0.3 Mhz increments. Method 2 doing a straight jump to 266Mhz FSB. It is feasile to do both - bring the system to 266Mhz FSB, then using method 1 to overclock further if the system is capable.

Method 1: disable TME to allow setfsb software overclocking

Two 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 pin1 on your debug port (spare unconnected 24-pin socket) to get the PCI2_TME pin4 to be logic 0. Shown in LIME for a 6910P or 6710B/6510B. Best done by attaching a 1k strong pull down resistor between those pins to ensure you don't short anything.

2. Disconnect the 3.3V pull up resistor to set the PCI2_TME pin4 to see a logic 0 to allow software overclocking.

(6910P): Lift one of resistor R1108's legs, shown in YELLOW here.
(6710B/6510B): Lift side "1" of resistor R362 and route it to GND as shown in YELLOW here.

Method 2: Set PLL to run at 266Mhz

FSLC FSLB FSLA CPUFREQ (PLL)
.....0...... 1......0.....200.00 <-----default
.....0...... 0......0.....266.66 <-----b-i-g overclock

This involves disconnecting or rerouting the FSLB pin so it's at a logic 0 (266Mhz FSB). 200->266Mhz is a pretty big overclock which may also require doing a BSEL voltmod to get the CPU operational. You'd very likely also need to write CAS=6 into the 333Mhz SPDtable entry as described below.

(6910P): Disconnect FSB at either point shown in ORANGE here and route the FSLB pin to GND.
(6710P/6510P): Disconnect R314 from the circuit, disconnect it from 3.3V and route to GND as shown in ORANGE here.

EXTRA: CAS=6 in the 333Mhz SPDtable RAM entry for higher levels of overclocking

If using method 2 above then RAM timings will still boot using the original SPDtable entry for 333Mhz yet be operating at 444Mhz. Meaning you should at the very least write CAS=6 in the 333Mhz SPDtable RAM entry to slow the timings down. That can be done using Thaiphoon Burner as shown here. If using method 1 then this will provide a higher stable overclock.

Softmod instead: dual-IDA mode

This is not a hardmod in the sense that a modded bios is flashed from http://forum.notebookreview.com/hp-...0-6910-6710-6510-2710p-2510p.html#post6654683 . Then Throttlestop can unlock extra voltage, a lower SuperLFM voltage floor and extra multiplier. The extra multipler providing a dual-IDA overclock. This may be preferred by those that do not want to void their warranty. Eg improved performance:

T7300-2.0@x10 -> 2.2@x11
T7500-2.2@x11 -> 2.4@x12
T8300-2.4@x12 -> 2.6@x13
[email protected] -> [email protected]
T9500-2.6@x13 -> 2.8@x14

Best overclocking possible?

Combining the dual-IDA bios mod to provide an extra divider and voltage and setfsb PLL overclocking would give the most overclock flexibility.

Please report your experience in implementing any of these overclocking techniques.

 

Hello,
I own 6510b without WWAN (TME_READBACK is 1) and I must report that method involving debug connector does not work, because resistor R364 is not present on the board. It could be easy fix ,if someone locates its position. Then I would just solder both ends together instead of putting 22Ohm resistor there considering that on debug port pins 1 and 2 is 1K resistor.

Other method with pull up resistor R362 seems too tiny work to me.

 

Hi,
just tryed the DEBUG PORT method.
but ive got a problem with setFSB. if i press get FSB i ever get PLL ID ERROR
furhermore i dont know if in register 9 should be 00100101 or 01100101?
maybe this is the reason for the PLL ID ERROR?

 

Nando4,

You seem to have everything I need in one place. I was able to get one out of 10 machines to overclock. I got a taste of it and it is working as I need. However, I need to get the other machines overclocked too. I'm stuck in a place where no one wants to spend extra cash. My only choice...to overclock. But I can't find the JP52, (AKA debug) Port on the motherboards. Can either describe where it is, or post a picture with a circle around it. My eyes are not what they used to be.

Per the Media Services Library 6910P systemboard pics, I've highlighted what I believe is the debug port below:



Since you'll need to disassemble the system to get access to the debug port consider you could then just do a 200->266Mhz PLL pinmod to overclock the system. Before doing that ensure you've slowed down the 333Mhz RAM to run at CAS=6. It may also need some VID mods to give more voltage for stability (either on the CPU or voltage regulator). These issues are covered in http://forum.notebookreview.com/har...pll-pinmod-overclocking-methods-examples.html .

Please followup and advise if you get a successful 6910P overclock. Thanks.

 

Hi!
I am using 6910p, z used modded bios so I can use x11 multiplyer.
But how do I do this?
2. Disconnect the 3.3V pull up resistor to set the PCI2_TME pin4 to see a logic 0 to allow software overclocking.

I opened setfsb an use the ppl above, it detects the freq. but when I want to change, the fsb and other just jumps back at 200...

How do i remove that resistor, and where do I find it, some more detailed instructions or pic.

Thanks I hope someone still waches this

 

I`ve done it , will post details and howto later today.
.....
You put your laptop upside down and there are three screws you unscrew(X keyboard sing next to it). They stay in the laptop. Then you put the laptop on the table, and open it, on the top of the keyboard there are four pins, you push it in/down so the keyboard can be lifted.
Lift slowly and disconnect the two ribbon cables and put the keyboard aside.
Remove the RAM.
Under the ram there is some shielding, its like a sticker remove it, and the chip is exposed. A magnifying glass is useful for the next step. Use your soldering iron to remove the resistor like pointed in the picture. Put it away and make sure there is no connection. Then next to it you will see an empty space only two dots of solder.
I just soldered them together with a small amount of solder, the resistor is too small to put back but not impossible( I have cheap equipment). Put the laptop together and profit.



Have a nice day!

 

Hi again,
im running too a x11 multi and runs good.
Now I'm trying to go further with SetFSB. But if i try to get FSB i always get PLL ID ERROR. Alredy tried some older versions but always same result.
Maybe it's because of the modded BIOS or my gemran Windwows 7?
I've chosen Same settings as you but can't get FSB. Or is it just luck if it works or not, and i'm not lucky?

And can you show me what to do at this step, maybe its the only alternative when SetFSB doesn't work for me.

Greetings

 

I dont know exactly, but I think you need to remove all conections to pin 57 (you need some insane soldering skills) and use a peice of wire to go to gnd and you need to flash your ram or something becouse 400mhz ram will not run at 266Mhz FSB, mine stops around 260.
Did you do the mod I did? If you didnt the setfsb doesnt work, but in my case, it didnt say pll error it just didnt set the fsb in jumped back at 200.
I use the mooded bios too, windows shouldt influence this.

 

Hi,
ok, that sounds possible to disconnect the pin. But in fact, the setFSB method sounds more flexible to me and is my preferred way.
So, i take the version you have. Maybe you can mail it to me, so i have a really working version for my laptop? And can you show me the diagnosis page? maybe there are some differeces.
I did the DEBUG PORT mod some time ago, but stopped doing anything because of the setFSB error. But now i want to get this thing running
thanks for your help.
greetings

 

Found that HP interchanged SLG and ICS PLLs on some later Elitebooks. Maybe they started doing this earlier too?

You can use setFSB's diagnosis function to check the PLL ID bits. Details of how to do this are in DIY eGPU on Tablet PC's: experiences, benchmarks, setup, ect... - Page 5 .

Alternatively, you could disassemble the system and identify the PLL by seeing it.

 

Here you go, I hope it helps.
I got the setfsb fom here:
SetFSB_HomePage
Version 2.2.134.98 (Freeware)

Remove the ram under the keyboard, and see if you have the same chip. Its under black label.

 

Ok, thanks a lot so far.
I indentified my PLL now. It is a SLG8SP512T(maybye the PLLs are different in ATI ind Intel boards?), and it isn't supported by SetFSB. All SLGs in SetFSB gets me a PLL ID ERROR.
If I choose SLG8SP513V and press Get FSB my screen turns black and my laptop is switching itself on an off until I remove the battery. Then i can restart normaly. Should i remove the DiagPort mod before trying to get fsb?

Hmm so the is no chance to get some extra MHz for me?!

Greetings, Katze88

 

Mod you should use in different on each PLL, so this thread is no good for you. You need to find schematich for your chip and do the mod acording to your PLL. Where and how I can`t help you sorry...

 

Plan B: get an X9000 in it and then use ThrottleStop to unlock the multiplier (and undervolt if possible). A bit expensive but efficient



Cheers.
