Ei Systems 3090

hi

Just dug out my old laptop - fancied tarting it up a bit.

i have just replaced the screen - want to sort the processor out.

seen a thread on this forum thats now closed - some guy is asking for processor advice.

http://forum.notebookreview.com/threads/e-system-1-6-cpu-upgrade.243801/

i currently have this processor - http://ark.intel.com/Products/Spec/sl8vz

if anyone can have a read through and help me that would be great.

i want to go with the fastest available - which seems to be a t7600

http://ark.intel.com/products/27257...r-T7600-4M-Cache-2_33-GHz-667-MHz-FSB?q=t7600

my board and spec is exactly the same as the guy posting - so does anyone think i can run the t7600 ok ?

the only problem i can see is the fsb is 553 and the t7600 would be 667mhz

any help would be great.

thanks

 

First of all, the fastest processor for Socket M is T7600 G, not T7600. It has unlocked multiplier and can go up to 3GHz if you're lucky. To determine whether any of those will work, you should check what chipset do you have. Looking at it is be the best way, software not being reliable.

 

Northbridge Intel i943/940GML rev. 03
Southbridge Intel 82801GHM (ICH7-M/U) rev. B0

 

oberkorn28, as I said, software is unreliable. 940GML doesn't support 667MHz FSB CPUs and T7600/G; 943GML does. You need to disassemble the laptop and check for yourself.

 

i have ordered a replacement bottom case - so when that comes I will check the board.

that Sandra software says its a 940gml - but I will physically check.

can I get back to you ?

 

oberkorn28, sure, you can PM me once you check.

 

hi

cant seem to be able to pm you.

can you help me locate the info - taken the back cover off but cant see anywhere on the board thats got the numbers i am looking for.

thanks

 

oberkorn28, it is usually located near CPU and covered by heatsink.

 

hi again

ordered a new processor - an Intel Core Duo T2350 1.86 GHz Dual-Core SL9JK (533mhz) - fitted it - not working, power light stays on, hdd light flashes and turns off - machine goes no further.
trying to see the board spec but cant find anything indicating either 940 or 943 - the only thing is this - a stick on copper - Foxconn 40GL41041-00 Rev a 070108
have i got a dodgy processor, as i thought that either way my board could take this processor, or am i missing something.


thanks in advance.

 

oberkorn28, put old cpu inside, download and copy cmospwd to bootable MS-DOS flash drive (may require some additional files - haven't done this in years), boot it and run cmospwd.exe -k, turn off and change to new cpu - should work. If doesn't work, then return the CPU. The number on heatsink is its part number, doesn't refer to motherboard. You shouldn't have picked Core Duo anyway, it's not fast enough for modern computing, though better than your Celeron. You need some Core 2 Duo at least.

 

hi

thanks for that.

the cmospwd thing seems really complicated - is there an easier way ?

i physically cant find anything on the board indicating if its 940 or 943.

thanks

 

Bugger.

Messed around and seem to have killed the bios

Machine won't boot.

Anyway I can restore the bios. Or reflash it?

Thanks in advance

 

well after unplugging the battery on the board all night i have been able to boot (several times) into windows and all seems ok.

it added a few bits of new hardware on first boot - but back to normal now.

so back to my original question - is there an easier way of getting the new processor added - that cmospwd process scares me !!

 

HELP

machine was left on all day - now wont boot stuck in loop.

can i reflash the bios ?

can anyone help ?


thanks

 

oberkorn28, in similar situation (new CPU should be recognized, but won't boot at all) cmospwd -k was the only solution that worked for me; everything else, including what you mentioned, didn`t. The command I mention does the same as removing CMOS battery (which is often very hard to access inside notebook, sometimes even soldered) - nothing to be afraid of, and it should resolve BIOS issues. Reflashing BIOS... well, it is the usual practice to flash latest version prior to upgrade. While reflashing the same version may help, you should flash BIOS only when system is 100% stable i.e. with old CPU. Oh, and the boot loop almost always means Windows problems, not hardware.

 

Any chance anyone knows where I can download the original bios so I can flash it back.

Thanks

 

oberkorn28, why are you so keen on believing your notebook's BIOS is corrupted? Did you flash modified BIOS or what? Reflashing BIOS won't reset all BIOS settings and solve BIOS settings corruption; removing CMOS battery or running cmospwd -k will. Disassemble it completely and remove CMOS battery for couple minutes if you're afraid of cmospwd.

 

hi

i am sure its a bios issue because i downloaded that cmospwd file and double clicked on one of the elements of the program (ioperm.exe) - it briefly opened a dos window and then shut the window.

ever since i rebooted it has either not booted or booted and crashed shortly afterwards.

would a corrupt bios work intermittently - as the machine does occasionally boot.

i just paid that bioagentplus place £25 as they said they had an updated bios - but now they havent - so i am chasing them for a refund.

cheers

 

oberkorn28, you should have followed my instruction. =/ Use another machine to make a bootable DOS usb flash disk, copy cmospwd there and run cmoswpd.exe -k when booted from this flash disk - or disconnect CMOS battery for couple minutes. Either should solve your issues. Good luck!

 

hi

i have disconnected cmos battery for a while and when inserted it loaded default settings - as expected - but it still wont take new processor.
if i follow your instructions above will that let me put in the new processor ?

and one last thing - how the heck do i create a bootable usb stick using windows 7 - cant seem to work that out.

thanks so much

 

oberkorn28, did you put new processor right after disconnecting the cmos battery, before connecting it back and powering the system? If no, try it. If yes, cmospwd won't help either and I'm out of ideas, but you should try to return the CPU, it may be faulty...You can create bootable USB stick using Rufus, but again, if removing CMOS battery for couple minutes doesn't help - cmospwd won't either, because it does absolutely the same.

Oh, and maybe it's time for you to get a new system. =\

 

i didnt put the new one in before bios loaded new settings - will try that.

i have several new systems - but this is an old laptop i wanted to keep for a spare room - i bought a new screen and casing - so hope i dont have to bin it just yet.

can i not try flashing the bios - and does anyone know where i can locate the original bios to flash it with ?


thanks.
