Core 2 T9300 upgrade fail?

OK, this past weekend I purchased a new CPU fan and Core 2 Duo T9300 CPU for my Toshiba Qosmio G45. I have had this upgrade planned for two years, but didn't want to open her up until something broke. When the CPU fan went, I figued I was going to have the laptop open anyway and went ahead and purchased a used T9300 off eBay.

The motherboard uses a 800 MHz PM965 chipset and a C2D T7300 . The next model of this laptop was exactly the same - motherboard, screen, BIOS, case, hard drives- except it had a T9300 and some decryption chip for an external cablecard tuner.

So I put the new processor in and button everything up. The computer does not turn on. Now I used the exact CPU listed in the newer version of the laptop (speed stepping SLAQG). The laptop wont even boot into the BIOS, or display the motherboard fault (indicated on Toshibas by a blinking orange plugged-in light).

After several attempts to get it to run, I pulled the new CPU and put the old T7300 in and everything works.

So my question is what could be wrong? A DOA processor? Has anyone heard of any instances where a 800 MHz FSB Penryn CPU did not work in an Intel 965 chipped laptop?

 

Have you updated your BIOS and chipset drivers?

Also the CPU could be defective?

 

The BIOS is up to date.

 

When I upgraded my old Toshiba's CPU, I was ripping my hair out trying to figure out why it wouldn't turn on once I put everything together. I opened it back up and it turns out I forgot to "lock" the CPU into place in the socket, which apparently cut power to the whole unit. Perhaps you simply forgot to do this as well?

 

I tried that too. It was fully locked into place. When the CPU is not locked in, the computer will show a motherboard fault (that blinky orange light I mentioned earlier).

I am runner 2.20 version of the BIOS, which states:

So my computer should have both cablecard and penryn support.

 

I suspect the CPU, can you try it on another laptop? or even return and get a new one?

 

This does not correlate to incompatibility. When a CPU is incompatible the computer should turn on it just won't display anything.
So if it doesn't turn on, it could be a dead CPU

 

I did return it, i'll order a new one off eBay. Does anyone know if the core stepping SLAYY and SLAQG models are interchangable? Would a BIOS recognise one but not the other?

 

Should recognize both. The models may refer to boxed/oem IIRC.

 

Hey guys, just an update on my G45-AV680. I purchased a new T9300 (SLAYY) off eBay. I attempted to install it but it just dosen't work. The CPU fits in the socket, there are no bent broken pins, but when I hit the power button it does not boot to the BIOS screen. The only thing that happens is the power button lights up. The fans do not activate, nor does the CD drive spin up.

When I put the T7300 back in, the computer boots fine.

The BIOS shows it is up to date, running version 2.2 This is the same exact BIOS used for the G45-AV690 that runs on a T9300 CPU. The BIOS version clearly states there is updated features for the penryn processor.

Anyone have any ideas what may be going on? I have never heard of Toshiba locking down components, especially the CPU.

 

Okay doesn't boot or doesn't POST? If an incompatible processor is installed, it should power on, fans should spin but it won't display video.

 

I mean post.
The fans do not spin up, the media buttons do not lights up, and the screen does not turn on.

 

Weird how the fans don't spin up, and nothing lights up. My Dell E1405 I tried to upgrade with a wrong processor and it powered on with the fans spinning and LEDs lighting up but no POST.

Maybe it genuinely isn't upgradable...odd. Have you scoured Google and seen if anyone else has upgraded this Toshiba model? 2 DOA processors are highly unlikely.

 

I have searched everywhere with no results. I ran into some problems like this when I tried to get the cablecard tuner for the laptop. The same model included with the newer G45 would not work in mine. I figured that my motherboard didn't have OCUR support.

That is the only indication that the newer version may have a different motherboard.

Even if I can't upgrade with a penryn, I would like to know if the compnents are locked so I don't blow another wad of cash on a useless T7700.

 

T9300 is SRR, not MV.

 

Do You hear some beep code when You try to power up with new cpu fitted?

 

This sounds like terribly bad luck. Scares me all the more because I'm about to do the same thing (T5450->T9300) to an Esprimo Mobile U9200. Than again, I read about Toshibas refusing to POST with HDD in the optical bay, and experienced first-hand a Toshiba refusing to POST with a new DVD±RW instead of an old CD-ROM so who knows what else they keep locked-down...
I'm keeping my fingers crossed and hope your upgrade will turn out well.

 

Myxal, this may have nothing to do with this therad, but I sucessfully upgraded from a T4500 to a T9600. So, as you said, it is just bad luck

 

Again make sure your BIOS and chipset drivers are all up to date. My Vostro 1500 processor upgrade went very smoothly.

 

BIOS is up to date as stated before. It is curently using the same BIOS as the T9300 equiped twin.

There is no sound when booting. The CD drive will make that "kuthunk" noise like when it is powered up, but that is just the reader head moving.

As for chipset drivers, I keep everything up to date so I do not think that is the problem, especially since it never gets past post and therefore any windows drivers are useless anyway.

Looks like the eBay seller is going to make the return difficult. What a pain in the .

I wonder if a T7700 will work.

 

OK, so I checked a little deeper. The G45 AV680 has a mother board with a part number FTUSY4 while the G45-AV690 has a part number of FTUSY6. I have compaied high resoluition photos of both boards and they are identical. They should be swapable, but I am not willing to pay $500 for the ability to run a Penryn processor.

While researching this issue, I ran across this little article:
Penryn Processors and the GM965 Mini-ITX Mainboards : Logic Supply Blog

While the mother board is totally different, it does show that Penryn support requires some hardware changes in addition to BIOS update. I am willing to wadge some money that the difference between the FTUSY4 and FTUSY6 is a resistor or two.

Wish I could get a schematic of the boards and see what components are different.

 

lol don't sweat it for a processor upgrade. Just go to like a T7500/T7700. I think j0ker was selling this T7300 for 35 shipped..

 

Yep, $35 shipped anywhere in the US: http://forum.notebookreview.com/computer-components/542798-fs-intel-core-2-duo-t7300-2-0ghz.html

 

I wouldn't even bother to upgrade the cpu from t7300 to t7500. A 10% boost is almost non noticeable. But too bad you cant upgrade, going from t7300 to t9300 is a nice upgrade. With faster speed, and lower temperatures.

I a sager 2090 with t7300, upgraded that baby to a t8300, the temperatures dropped 6C without doing anything.

 

Sometimes you can find a good deal on a T7500, just saying, I've seen it for ~100 bucks. Not much going from T7300 to T9300, many benchmarks show no performance gain with extra cache, at least for gaming/normal use.

 

So Penryn #2 has been returned. I think I will put off a T7700 or T7800 upgrade for a while so I won't run into any issues on eBay.

If anyone happens to be getting rid of a T7700 or T7800 please PM me.

 

Hey man, I just upgraded from a t5750 on an acer 7720 to a t9300. I went to intel.com and ran throughthe chipset identification utility. I had a pm965. I download the latest inf files. I checked acer to see if I had the newest bios. When I was doing the upgrade, there is a distinct clicking noise when you unlock the cpu but not when tightening. To me it sounds like you didn't tighten it well. That cpu should work.

 

Nope, the T9300 Penryn is not compatable. The early G45 AV680 was released in early 2007, and was one of the very first Windows Vista HD-DVD units. The next version that featured the Penryn CPU was the AV690 which was released a year latter.

The AV680 and AV690 are identical. Same HD-DVD, hard drives, case and screen. But the part numbers for the motherboard are different. It appears some early PM965 were not built for the Penryn processor, though most could receive a BIOS upgrade to make them compatable.

The BIOS for the AV680 and AV690 are the same, and mine is fully up to date. I'm using the latest drivers for the 965 chipset from Toshiba's site. The CPU was locked in place. The only answer for this that I can come up with is a hardware incompatability with the motherboard.
