Any SXPS Bios available with advanced features ?

Hi,

Is there any modded bios available with some advanced "oc" features. I am trying to undervolt cpu from bios, shut down one core, slow down clock, change fan from silent to normal mode... etc... (This wouldn't be too much to ask from regular desktop board)

Until I boot and start windows my cpu is already too hot. (my notebook is ok, just cpu was upgraded and it's overheats a bit.)

Does this original bios has some secret menus to tweak those settings ???

Thanks.

 

I believe unless you break into Dell and put some engineer under gunpoint, you won't get any of the things you asked for from the BIOS.

 

lmfao. We can dream. They won't even let us run the laptop properly, why would they let you OC? lmao

 

what cpu did u upgrade to?

 

As I understand it, there is a registry tweak which will tell the computer to ignore one of the cores on startup. I remember asking about this as to whether I could disable one of the cores in the device manager, then someone said that there was a way.

I'm sorry I can't be more specific but it's too late for me to go galavanting round google right now

 

To use only 2 cores for the entire time (i.e. get 25% what you paid for), go

Start > msconfig.exe > Boot > Advanced > # processors set to 2

 

killaz05 : I upgraded to Q9000 ! - it works only with open bottom. Pipes are too slow in heat discipation...

funky monk : Thanks for idea. I am reading dochelp for /onecpu setting

fred2028 : Great, I will do this and test it.

I need better cpu cooling, and I don't know from which side to tackle the problem, cpu fan, better sink, .... was thinking about adding fan from old mobo that was used on chipset there, it's pretty tiny one but still doesn't fit above heat pipe....

 

From what I remember the msconfig thing only affects the cores in the boot sequence. I tried it once and my computer didn't run very well (not as in slow, it just ran badly) so I put it back.

Also, "only 2 cores", that's all that most people have.

 

u upgraded to a Q9000? does the computer run? it works okay with the bios? I really wanted to do this upgrade please give me info on the change out... any specific mods??? Thanks for any info

 

FYI: The msconfig processor "tweak" is not a tweak at all, but rather an old and stubborn myth that won't die.

You will not get any performance increase by changing the number of processors in msconfig.

 

It works out of the box. No problem with bios at all. Problem is that that cpu goes hot as hell. CPU voltage is correct. But cpu uses 45W while P8600 only 25W. I need some inspiration how to deal with this... if I could order sinks and fan for 1645, coz i7 is also 45W cpu...

I am using BCDEDIT to restrict CPU to only 2 cores.

PS:

So, I do understand that most of people have "only" dual core, but... wanted to have this little monster notebook running my development tools and lots of VMs, so also got 2x4GB of cheap Transcend ddr3 (apple compatible 1333Mhz), I can recommend that ddrs, they perform well for the given price (260 € .

 

well that is great news... Now I will do the swap when I can get a Q9000. I have a t-series which is a 35W as I have come to understand. I am currently at 144 degrees F which is fine for me. How much hotter is the Q9000? I agree with you about using the heat sink from the 1645 but is the i7 a cooler unit overall even though it uses 45W as well?

 

When I had an i7-720QM I put it on 2 cores and Task Manager only showed 2 cores. When I took it off, it showed 8.

He isn't trying to get a performance increase, more of a heat and performance DECREASE.

 

Euh... maybe you wait with that upgrade. Here is what happens:

- I have installed Win7 on original config (P8600).
- I have used bcdedit to set number of cores to 2 and later 3.
- Then installed rmclock and have set all voltages to 1.0500V

All works perfect, except during win7 start cpu gets hot. Windows experience is here 6.1 (6.1,6.1,6.7,6.7,7.3)

- In order to turn on 4th core, I have to raise min/max voltages from 1.0500 to: 1.0750 and max to: 1.1250 add cooling, etc, etc....

Only then windows 7 will boot, after I start windows sucessfully I can lower all voltages to 1.050. Strange issue happens only when 4 cores are running is that some processes (antivirus) is taking 40% of cpu. Windows experience here is 6.7 (6.9,6.9,6.7,6.7,7.3), as seen narrowneck is not cpu (6.9) but gpu 6.7.

I don't know if 4th core is damaged, or bios doesn't support it correctly but I find very strange that there is so big difference between running 3 and 4 cores. Boot up voltages are strange issue as well.

Finally I have run some tests in sisoft Sandra q9000 vs i720qm:

Dhrystone ALU : 42 vs 38 GIPS (q9000 wins by 8%)
Whetstone FPU: 26 vs 31 GFLOPS

At ebay.com there is someone selling 1645 mobo. I would have gone for that upgrade if I hadn't already got q9000 cpu.

 

would it be cheaper though to change to a 1645 motherboard plus i7 CPU or would it be cheaper for the q9000... as far as voltages my T9550 is running at 1.1875v right now...

 

Cheaper the q9000 it is - but i7 much safer looks like.

-Current temps are 45C idle, 60 on load with 4 cores always locked on 1.0500V.
-Current temps are 40C idle, 50 on load with 2 cores always locked on 1.0500V.

Still having problem of processes go crazy with 4 cores and cpu too hot on boot time. Just looking at cpu bios table mod, to lower VCORE at POST.

 

Well keep me posted on how this is going.
