Need to overclock my T9400 1737, to 3.08Ghz

Ok the new Montiveniea chipset is very stable my 1737 is running a T9400 2.53Ghz right now 1066mhz FSB and with the 6MB of cache, running at a stock 2.53Ghz does not do it justice.

I have already installed an 80GB SSD and 2GB Intel Turbo memory so the battery savings these are providing I am willing to give them up. Should still get 3hours even over clocked. With normal useage no gaming I am well over 5 hours on battery, If I over clock I am still willing to go back down to 3 hours of battery time.

does not have to be exactly to 3.08Ghz just as long as its over 2.53Ghz


But I have no idea how to even begin.

 

First of all, your CPU temps at moderate load had best be the lowest of the low to even consider overclocking the CPU of a laptop where of course the space is restricted unlike a desktop.

Secondly, and I'm sorry this is going to sound a bore, but although the general forum search button is not working, the search button at the very top is. Use it; I know there are plenty of posts on this type of thing. I also know that the majority of them will tell you not to even try.

Now, if you were to talk about overclocking the GPU, that's a different matter.

What on earth could you need more than 2.53GHz for on a laptop anyway?

Turbo memory and an SSD? Surely there is no need? Turbo memory only really saves you battery by not requiring the HDD to spin up as frequently; a moot point when you have an SSD.

 

To put it simply, you can't. There is absolutely no way to overclock your processor in a Studio 1737. And I share my curiosity with Fragilexx, what could you possibly be doing with that laptop that needs more than a 2.53GHz Core 2 Duo?

 

Although according to Everest, I am so damn good that I overclock my P8600 with only the power of thought.....no physical change required:

 

Yeah my T9400 according to CPUZ, CPU ID runs at 2.66Ghz at times of heavy use,

 

LOL, do you class overuse as reading one web page and running Everest? Because that's all I was doing

 

I tried BSEL ping modding, but when you do that the CPU locks itself at 6x multi, and BSEL only works with lower FSB cpus (like my T4200 800fsb).

If you have the money to buy an 80gb SSD and 2gb Turbo Mem, surely you have enough money to just buy the fastest C2Q you can find?

 

quads wont go into a studio 17 as the laptop was not designed for them, there is no bios support etc.

just buy a T9800 for around £200 and keep your t9400 incase you need dell to fix your laptop and you might need to put that in.

 

Holy cow, somebody suggested spending £200 for 400MHz more processing power?

Owais, I wish I had as much money as you must have.

 

Naw I am gonna wait for the i7 core Nehalme mobile version once those get released the Price of the T9800 or something like that will drop to pennies.

Got my 2GB Intel Turbo memory for $40, and my 80GB SSD for $80 some price mistake it just rang up cheaper someone must have swapped an SKU sticker hehehe (me) teen girl cashier doesnt know the difference between a SSD and a tuner card.

anyways the SSD is blazing fast and uses like now battery power.

The main battery savings is that it creates little to no heat there for the fans don't need to spin up that show it give me about 6 hours on battery.

Mainly wanted a cheap free way to get more speed and sacrifice my battery juice savings.


Oh well I guess the T9400 will have to last longer. Runs Bluray at like 11% usage, but thats mainly thanks to Intels new Montevenia chipset

Only thing that would make the 1737 perfect would be Overclocking and DDR3 RAM. If I had DDR3 RAM I could probably get 7 hours.

 

You seem more interested in increasing battery more than anything else? Have you tried undervolting your CPU?

 

Naw no under clocking or under volting for me that can be bad for the CPU undervolts can be worse for the CPU than over clocking.

I will have to do some research and monitor prices but a T9800 should be a drop in in upgrade.

 

Umm, what? That's not true at all, undervolting cannot damage your CPU in any way, and it does not underclock the actual processor speed.

 

Lmao. The worst I've seen undervolting do is restart the computer because I undervolted below the lowest voltage.

 

Absolutely, undervolting is not going to harm your computer or it's performance.

Taken from the following link The Undervolting Guide with credit to flipfire

What is Undervolting?

Undervolting is a process which reduces the excess "voltage" given to the CPU using a software. This is widely used as a cooling solution and in my opinion more effective than any other cooling solution available (thermal paste, cooling pad, etc) at NO cost. Results can vary from 5c up to 30c drop in temperature, most will achieve an average of 10c.

Undervolting will NOT compromise performance at all. Underclocking and Overclocking (clock speeds) is whats responsible in regards to performance. Benchmarks will also prove that performance remains the same. Most beginners usually think and assume undervolting will sacrifice performance but they are wrong.

So you’re probably wondering how this works out and why Intel/AMD didn’t do this before hand..WHY? HOW?

Not all processor chips are built equally. Each individual processor have different voltage tolerances. Instead of Intel tuning each chip's voltage individually for the lowest voltage possible and risking instability, they made a fully stable standard voltage for all chips to run on. The problem is this standard factory voltage they put is quite high. Undervolting takes advantage of this by reducing it to the right amount.

This is also why some people can undervolt more than others even with the exact same model processor. It’s like the same concept for overclocking, some can go higher, some cant. Unlike overclocking, Undervolting will not void your warranty or damage your hardware.

Bottom line is.. There is no catch to undervolting.

*Advantages of Undervolting
- Cooler CPU (5 to 20c cooler)
- More battery life (15-30mins more)
- Less Fan noise & activity
- Longer overall notebook life
- Eco-Friendly


I'm sorry, I thought you wanted to tweak your machine for performance. Perhaps you should do some reading before you go and do something that will destroy your machine. You realise that it's because of folks like you that companies such as Dell lock the BIOS......... </Rant>

 

Has anyone ever tried a Quad in the Studio 17? The heatsink looks like the same meaty one they use (Foxconn like) in their M4400 and M6400. The chipset definitely supports Quads.

It comes down to BIOS support and pin support, but I guess till someone plugs one in and gives it a whirl, we'll never know.

 

There are Socket P quad-cores with 1066MHz FSB, so they should be physically compatible...nobody's actually tried it yet, though.

 

I would say ask Dell, but I never get any answer from them about anything other than they supply. Cowards

 

Dell's tech people are the last people I would ever ask.

 

What about the good old PLL pin mod?

 

For this chipset and a CPU that is already utilising an FSB of 1066MHz?

Besides, the mod you are talking about is incredibly time consuming and very very easy to complete destroy your system with. Even in your thread you had the PLL schematic round the wrong way - what would have happened if you'd played around with those pins?

 

You can still do a mod to go to 333mhz FSB.

let me check and get back to you

But also, if you post what you're going to do before you do it then other forum members can help solve such simple errors.

EDIT: just checked, I would have probably shorted out the motherboard since I would have beed connecting VDD to GND.

 

OK, my ignorance about the 333MHz FSB, was not aware this chipset supported that, just going to look it up now.

Of course, posting beforehand and getting response from other members is always a good idea. I was just using that as an example to show how complex it might be to perform this mod and how easy it would be to mess up. I think my advice is that if they read your thread and can't understand all of it, then they should leave well alone.

Also, a forewarning to anyone thinking of trying this; it should go without saying really, but this will invalidate your warranty....

 

No, it's not supported by the chipset.

But if you modify the clock generator (PLL) then you will have the FSB @333mhz.

just like when my chipset doesn't support 266mhz, but I can still overclock to 266mhz.

There are three pins on the clock generator that control the FSB.

They are FSLA, FSLB and FSLC.
look at this table for the values you can make your FSB (depends on your PLL though):

FSLc..FSLb..FSLa..CPU-MHz
L.......L.......L......266
L.......L.......H......133
L.......H.......H......166
L.......H.......L......200
H.......H.......L......400
H.......H.......H......reserved
H.......L.......H......100
H.......L.......L......333

So right now you have 0-0-0 or L-L-L (266mhz).
if you change FSLc to 1 (or high) you will have 1-0-0 or H-L-L (333mhz).
