CPU upgrade T5500 to T7200 on Toshiba U205 S5057

I (my roommate) have a Toshiba U205 S5057 originally equipped with Intel Core 2 Duo T5500 CPU, 1G Ram, 160G HDD
I've upgraded: Ram to 3G (enough to run Wins7 32-bit pro) on 240G Crucial M500 SSD

I also bought an used T7200 CPU on ebay and put it in, but I got Blue Screen of Death (BSOD) right after windows boot up and goes into desktop. Only if I use safe mode, I dont see BSOD anymore (Windows does recognize CPU T7200 @ 2.00GHz 2.00GHz so CPU may work???). BIOS version is 3.30, RAM and HDD is working properly (testes in other laptop), I put the T5500 back and everything is working fine again, no more BSOD

What cause of problem here, anybody had changed CPU before, what are needed steps I would need to follow?

 

That is really strange. I doubt the T7200 is faulty. If it were, the computer wouldn't boot.

If it works in safe mode but not when you boot up normally, it sounds like some sort of driver issue. My guess is power management. With the T5500 installed or while in safe mode, stop all power saving features and see if it works.

 

I did remove cpu driver and let windows install new one (safe mode with networking mode), still not helped.
I tried to re-install windows (delete all old partitions and do fresh install through dvd optical drive), bsod again right after I choose partition, so it may not be the driver (or not...), at this point I have to put T5500 back and re-insall windows, haven't put T7200 back since then.
I dont want to flash bios, it is v3.30 now (latest is 3.50 - both released in 2007) and I dont know how to do it, don't want to brick this brick )
what you guy do when first put new cpu in?

 

You should probably flash the bios. It is really simple. Downloaded it from the manufacturer's website and run the program.

 

Strange I upgraded a P205 to T7200 and didn't have your problem your having but I did also update the BIOS and from the model it does look like on Toshbia they have a BIOS update to 3.70 aka

This is the site I found with the model number.

Try to update the BIOS and reboot to Desktop and see what it says. But make sure to replace the thermal paste properly to all the heat sinks that need it.

 

cmospwd /k from bootable flash drive, turn off, change CPU might do the trick. If not, you'll have to flash newer BIOS.

 

Thanks all for helping me out! maybe it was my foul because I right after swapped CPU I boot in Windows 7 normal mode so it messed the driver up or maybe that chip is a bad one (probably not since it work fine in safe mode).
I contacted ebay seller, they sent me another T7200, this time when machine was first power on, I go in to BIOS setup (LOL for nothing but I just enter there) then I boot into safe mode (do nothing there LOL just hanging around devices manager ect...)
after that I boot into windows 7 normal mode and it worked.
So what I learn is after put any new hardwares in your machine, go into BIOS (for BIOS to verify or recognize them LOL) and boot into safe mode (with networking) for the operating system to give them suitable drivers.

 

That's good to hear this is why I always advise before upgrading your processor one should update their BIOS to the latest and then change the processor and enjoy the new setup.

 

It's got nothing to do with going into the BIOS. Your original T7200 was faulty, and yes a dodgy CPU will work in safe mode and POST but will cause BSOD's or fail to boot completely in normal mode. A dodgy cpu may also cause the system to freeze up or turn off randomly.

 

Aren't CPUs things that either work either don't work at all?

 

Weird because when was in safe mode (with networking) I used firefox to browse around and download drivers w/o any problems (so it "does" compute right LOL).
Only way to test whether or not that 1st T7200 is good is swap it in now but I dont want to do it LOL. (you all may know how PITA to change cpu on 6 years old laptop), good thing is it is now running faster than almost all of the ~$500 laptops nowadays (those with out SDD) =)

 

In all my years of OverClocking I've had CPU's with a plethora of odd issues due to a long life of maximum OC's or too much voltage that have damaged memory controllers, individual cores that needed disabled, required massive amounts of voltage just to post and so on. The T7200 probably wasn't OC'd but it may have been in a laptop where it was constantly overheating leading to the CPU becoming damaged.

 

That the one gain upgrading a older processor will boost performance and make a older computer more useful as well. I upgraded dv4, dv5, dv6 to t8100 and might go once more to t9300 just to improve the windows performance not to gaming performance but for everyday usage improvements. Plus it doesn't cost much to go buy used T9300 from eBay so it makes it a worth while investment since I plan to keep them for long time. That is the main reason to upgrade your processor long term investments. Plus I find it works really good for my laptops with processor upgrade to T8100 and having Windows 7x64 Ult Sp1 works very good with the upgrade. So there are gains you get that isn't immediately seen.

 

Like ram when data goes through it just gives back bad data if only a small part of it is damaged. So you don't see anything until that register or part of the damaged cache is hit, or a part of the program that can't handle the bad data crashes. Back in the hay day, the P90 I think it was had a flaw in its design that would cause an algebraic error that would rarly pop up. It was fixed by new drivers that simply avoided the flawed part of the cpu.

 

Actually, the t7200 is still end of life. Of best buys cheapest in store laptops, the Intel Celeron 2955U is about %30 faster, and the AMD E2-3800 is about %50 faster. In todays chips, the t7200 is that of the Intel Atom Z3740D. Laptops under $500 will have i5 and i3 chips which would trounce the t7200.

I did the same thing as you, I have a dell e1505 and updated the original duo in it with the t7200 in hopes of being able to ensure I could play most 1080p videos. It worked for the most part but it wasn't anything special. Youtubes 1080p was still out.

 

no it will not play 1080p video LOL lag lag and lag, 720p is totally fine though. Also, (read my first post for what I upgraded) my point was that: b/c of the SSD's upgrading, old machine is now responding much quicker than I can say even faster than those modern laptops that equipped with normal 4200-5400 rpm HDD, the T7200 is only faster than previous T5500 cpu in this old system that's it =))

I may put the maybe-faulty t7200 back to test later and let see what happens

 

Ahh yea, I was amazed at how my q6600 desktop gaming system improved with just the ssd upgrade (before I jumped to a new motherboard with a fx6300). SSDs are amazing, although I have been pretty happy with my new asus laptop. Disc speeds have been pretty snappy all around (I read that the hd used was one of the best performing platter based drives) and windows 8.1 ensures that bootup and resuming times are very quick. Which is good cause I need that 1tb of space for games and movies and can't be fighting with a smaller ssd drive. ^^

 

My nc8430 with t7200 in combination with potcplayer and coreavc would disagree. It wont play all 1080p content smoothly but as long as file is under 6gb in size it will run withoutclagg.

I think we both were referring to what didn't play... like you tube videos. Also depending on the profile used, even straight 1080p was not stutter free (mpc/ffdshow), and most of my videos use styled subtitles which slow it even more. God forbid the video was 10bit. My x1400 helps a lot in situations but if the video is 10bit, it is all up to the cpu.

 

Yes thats why you use coreavc as it alows both cores to decode oposed to other codecs like ffdshow which are still sc.

errr...ffdshow (and now LAV) has been multicore for quite some time now. And is updated unlike coreavc which stopped seeing the light of day in the end of 2011.
