CF-51 CPU upgrading

The CF-51LL is T2300 1.6 Duo
The CF-51 is a T2500 2.0 Duo

1. I just used Artic Silver 5 paste
2. no need for bios update
3. no problems, its the way I did it.

I just new you would do it.
I think she will be very happy with it.

 

Tried the T7500 upgrade with crucial 2GB CT25664AC800 ram on 3 cf-51 core duo machines a cf-51QG5EEBM, cf-51RC4KFBM, cf-51QG4DEBM. both bios V3.00 and V3.50 the Q machines with 256mb video ram and the R machine video ram N/A. None would boot to bios. Was hoping for a Christmas Surprise but got nutin' for Christmas here. Any way it seems limitation here is chipset these being 945 GM or PM. the T7500 worked on my gutway which was a 667FSB to a 800FSB, difference was it had 965 GME chipset. Must be the answer here. Merry Chrisatmas to All!.....Driller

 

Oh... so is that what the young people are calling it nowadays? :wink:

mnem<~~~ Walking euphemism ~~~<<<

 

OK, I bit! My Mk3 is now a Core 2 Duo T7200

I installed Speedfan and it reports the CPU is running right at 130 degrees. So I am watching that....

 

I have been running my T7200 + T7600 for about 3 weeks and no problems here at all. I am no gamer so it's just surfing + MS Word and never had a problem with heat. I watched it the first week I put it in but have not checked it since. It runs great, it has not crashed once since I put them in....sweet
Temperature 45-55 c (T7600)

 

Missed this little dragon snark. Actually, when you get to be her age there's a good chance the processor is gone. I believe the surgeon said something like "don't worry, I'm only taking out the nursery, I'll leave the playpen"

Hey as long as the firmware's not corrupt, it's all good. :wink:

Hard drive still hard? CHECK. Floppy still floopy? CHECK. Processor not going thermal? DOUBLE-CHECK...

 

:laugh: :laugh: Stop it...you guys are killing me :laugh: :laugh:

 

Is this measuring in degrees fareinheit or degrees celcius? The 130 would be close to what Toughasnails is getting on his and is close to what most of the cf-51 core2duos that I fixed up, if its in F degrees. 45-55 degrees celcius. The fan in these on some of the laptops seems quieter, the newer looking ones and my test bed laptop for the cf-51 has over 10K hours and was considerably dusty coming out of Arizona from buybest15 I think. there isn't much you can do to improve the cooling other than new heat pad with the AS5 paste and cleaning out the fan and its pathways with compressed air. Ain't quite like the cf-29 here.............Driller

just read something about speedfan4.4.2 that would in advanced user to allow you to adjust the FSB up to 800?, are my eyes decieving me? could this be a way to get the old T7500 to work on a cf-51? chasing rabbits again here....

 

A little OT, but I just did some speed test on the CF-51 to get a baseline to compare when the T7200 gets installed this weekend. Should I be impressed with these results on the Samsung HM160?

I'll post the results of the full test after I put the new CPU in and I'll check with 2GB ram against 4GB.
CAP

 

The test thoughput is similar to the results I get with the samsung with HD tune tests
The processer and ram will not change that result
You need to find a benchmark that loads up the processer

I posted this a month ago on Robs site , regarding what to expect for speed increases when you upgrade

 

I ran Passmark and it checked everything, I was just wondering about the HDD. I will run it again when I upgrade to theT7200 which is sitting here waiting for the weekend. I really have never needed to run any of these tests before as I've never had an upgradeble processor before. I have gathered that the 7200 was the best bang for the buck. The T2300 is the stock processor.
CAP

 

Driller,
Yes, that's Degrees F. I will run several things then go back and check, it runs between 130 and 150. But once I stop what I'm doing it cools right down to the 130 mark.
You're right, it sure is not the 29! One thing, I was a Industrial Maintenance electrician for the last 20 years and while using compressed air has it's virtues, I don't like using it inside a computer. I'll get out my brushes and clean it by hand. Doesn't make it better, I just like doing it that way...

 

Here is my results from Passmark

 

I have a newer version of Performance Test. Currently, with T7200, 370.8, prior to upgrade running T2300, 486.8. Something is wrong so I started a new thread.

***SOLVED***
It is highly recommended that you have the laptop running on AC power whilst running performance tests. Battery saving settings might prevent your CPU from upshifting to maximum performance!

Read but a few things went against each other.... The only Upgradable C2D is the T2500 51?

Pretty much the one I SOLD?
CF-51QG5EEBM

Did that to myself on the 29 and the 72.

 

I have upgraded three CF-51's
CF-51RC4KFBM "MK3LL" T2300 to a T7600 Core 2 Duo (Mine)
CF-51RC4KFBM "MK3LL" T2300 to a T7200 Core 2 Duo (Sold)
CF-51QG5EEBM "MK3" T2500 to a T7200 Core 2 Duo (Daughters)

 

did the T7200 upgrade on the cf-51QG4 model as well. I think the QG5 and QG4 have 256mb video ram listed in the bios and I think that is radeon x1300. I'll check and see , but I think that is correct....Driller

 

That is what my daughter has in the 51 I gave her for christmas.

 

Cool cause I can't find another 2.0 duo anywhere. Will be back in a few months with a 51 then to join in on the fun.

 

The T2500 is the best because of the better video card but my T2300 is great for what I use it for........even better with the T7600 . I still have a T7200 cpu + caddy looking for a home, no big rush for my other daughter's birthday is not untill July 13. Hope you pick up one soon and come back and join the madness

 

Will a card like this work in the 51? helping the person I sold it to go internal wireless.

or this?

Yes ,but only if it's a mk-3 or mk-3LL
The mk1 and 2's used standard m-pci cards like the cf-29's

 

it's a 3LL as pictured in the other thread. Found that out when I attempted to swap my stock intel card from my 29 to his 51 since he already had wires. His slot looks like this.

So, does anyone have the processor number off an original core duo from a cf 51? 1.66 would be best for me. I have a 51 coming and want to upgrade the cpu.
Do all of the core duo's in the 51's use the PBGA479 socket? With an original cpu number I can find all the core 2 duo's that are compatible.
I pulled a core 2 duo t7200 from a junk dv900 that I have, but it is a SL9SF. Which I think is a PPGA478.

 

From a Mark3LL:

LF80539 T2300E
5623B629 SL9DM

1.66/2M/667
INTEL
Exactly as it appears on the chip.
CAP

 

A mk3LL is what I have coming. The info below is from Intel's website. Toughasnails and Driller both reported that they have the PGA479M socket. But from your info Capt, this cpu should work.

T2300e 1.66 core duo original cpu
SL9DM LF80539GF0282ME TRAY C0 PPGA478 06E8 false

T7200 2.0 core 2 duo from hp dv9000
SL9SF LF80537GF0414M TRAY B2 PPGA478 06F6 true

 

This is from intels site...T7200..Sockets Supported - PBGA479, PPGA478
Intel® Core?2 Duo Processor T7200 (4M Cache, 2.00 GHz, 667 MHz FSB)with SPEC Code(s)SL9SF, SL9SL

Yes , the 51's use the PBGA479 socket
Check out here to ~Toughbook Talk~ Toughbook Discussion &bull; View topic - CF-51 Intel CoreDuo 1.66GHz to Intel Core2Duo T7200 /400/600

 

Check this out though. Make sure you check the box marked.. Show spec, stepping, ordering, and socket details

intel cpus


When you scroll down to the T2300E, you will find capt's posted cpu SL9DM. On the same line is shows the socket as being the PPGA478 This is where I am confused. You say it's a 479, but Intel says the cpu is a 478. Do you have the spec number for the T7200 that you installed?

 

The best bang for your buck is the T7200 ($40.00-$55.00). I have a T7600 ($130.00-$175.00) in one of mine but did not see much difference at all for the extra $100.00 that I paid for it. We did not get the T7500 to work , it has the FSB speed of 800 MHz and the T7200-T7600 is a FSB 667 MHz

 

I have a T7200 in my hands right now that I got for FREE. I am trying to get confirmed information on the socket number and or specific processors that work in this upgrade. Such as SL234 or SL987 etc..
Intel made the T7200 in 2 different and mutually exclusive socket configurations. I have a 50% chance of it working. Not a big deal since I have a free cpu. It would be a big deal to those people buying one.
You and Driller say 479 but Intel says 478. I don't take everything that Intel posts as being gospel. But, I could not find anywhere in thread thread that listed a specific cpu spec number that someone has working. I would like to know before I tear this thing all apart and find out this cpu won't fit.

 

From what I have read Intel says it suports both. The PBGA479 and PPGA478 . I do not have my T7200 but the T7600 is SL9SD

 

Intel lists that spec number as follows.

SL9SD LF80537GF0534M TRAY B2 PPGA478 06F6 true

I don't know why it says PGA479M on your mobos, but Intel says that a SL9SD and Capt's original SL9DM, along with my SL9SF being a PPGA478

I think the sockets supported statement refers to the fact that it is manufactured in both sizes. One cpu won't work in both of those sockets.

Edited with more info...

I found some more info on this . vaio-cpu-upgrade-question-socket-478-ppga

I get the idea that all core duos and core 2 duos are either socket pga479m or solder on. Intel calls the pga479m a ppga478, because the cpu only has 478 pins.
The other package Intel talks about PBGA479 is the solder on, non socketed cpu like in a cf29.

 

Ok, I went and got my CF-51 MK3LL with the T7200 in it. The numbers on the cpu is SL9SF which is the same as yours.

LF80537 T7200
7702A769 SL9SF

 

In my wife's Cf-51 MK3LL:
Intel® Core™2 Duo Mobile T7200 2GHz 4M 667MHz SL9SF

Working fine with a noticeable increase in speed.
CAP

 

Thanks for the info. That's the exact cpu that I have and it's now waiting to be installed. I also snagged 2-1gb pc5300 sticks of DDR2 from that dead dv9000.

This CF51 should really cruise compared to my 1.7ghz Pentium M CF50 that I use now as a daily machine.

 

Something I found out, which I don't recall seeing mentioned in this thread, is the latch at the front (opposite the LCD) side of the CPU socket. IIRC it swings toward the front and the chip comes out a lot easier with it open
CAP

 

i know that we've tried to put in the T7500 in these cf-51's with no success so far. any of the 667 FSB chips should work and all of the T7200's i've installed have worked in all of the core duo cf-51 models so far. I've done it with those that have the V3.00 and V3.50 bios those with the video ram of 256mb and those without. as best i can tell it doesn't matter which one as long as it origionally was a core duo. i wanted to try a cf-52 using the cpu with a 800FSB like say the T9500 but haven't wanted to spent the money to buy one at that cost.also wanted to try out the T9600 which is 1066FSB?(not sure if that's right) funny thing is I got a gutway laptop 6812 and a 6862 m series that the T7500 and the T9300 works on. i think one is 800 and the other also 800FSB. difference being the graphic chipset is GME965 vs GM PM 945 for the panasonics.........Driller

 

You mean like shown in these pix I stole and cropped from the net?

 

Exactly, in the first picture you can clearly see the latch opposite the USB ports. It was giving me fits until I figured it out. I'm surprised no one ever mentioned it in this thread, but then I didn't either.
CAP

 

Cap, sorry, but what latch are you referring to?

 

Look for the brown piece of plastic ON THE PROCESSOR SOCKET ITSELF. It's at the end of the socket opposite the USB ports in the first pic; in the second pic it's opposite the parallel port and it's flipped up.

mnem
Unlatched.

 

The latch is just as mnem said, but the "flipped up" might be confusing, its not the big "L" shaped thing, its a small lever between the two pale bits. It seems to somehow clamp the pins on the processor inside the socket as it doesn't grab the chip board anywhere.
CAP

 

Thanks, guys. I'll keep that in mind when my next 51 arrives. It's supposedly a 51RC4KFBM, with bio-metric reader (which I haven't figured out what it's about - fingerprint scan instead of password??). Still scouting around for an affordable T7200 and thermal compound.

 

Its real cool....you can even start the 51 with a scan of the finger. Works good with XP but its a little flakey in W7. For thermal compound I use "Artic silver 5"
http://cgi.ebay.com/Arctic-Silver-5...060?pt=LH_DefaultDomain_0&hash=item3a61fca38c

 

When you pull the heatsink off does it rip the CPU out with it?

 

no, it shouldn't unless you had something like crazy glue on it. with the thermal pad material I've used and reused the heat sink. assembly just remove the 4 screws and gently lift it out. the socket just flip back the "lock" and it lifts out effortlessly. the cf-51 is amazingly easy to swap out the cpu. just the KB ,pan underneath and there it is. the heat sink is larger for the model you're talking about.......Driller
oh yes, there is the speaker cover assembly and connector , but that just snaps off from the backside of the hinge area, hope this helps

 

I agree , the 51 is very easy to work on and it only takes 10-15 minutes tops to change the cpu.
