Can upgrade CPU T6570 to P9600

Hello everybody. This is my first thread here, after spending about ten minutes to get captcha number accepted I will be quick: can update my notebook (Packard Bell EASYNOTE_TJ65-DT-130IT) replacing an Intel Core 2 Duo T6570 (2.10Ghz/800Mhz/2MB) with an Intel Core 2 Duo P9600 (2.66Ghz/1066Mhz/6MB)?

Questions:
1) P9600 is a good choice? I can get it used for 210$ shipping incl. real CPU not QS/ES
2) there is any chance that BIOS will not recognize it (some models from TJ series have the P7350)?
3) should the laptop run cooler with the new CPU (TDP 35W vs 25W)?
4) will the mainboard set the divider in order to get the DDR running at 800Mhz instead of 667Mhz (see cpu-z screenshots below)?



Many thanks sorry for my not so elegant english

 

Don't think it will work, difference FSB, different architecture.

 

Chipset 45 series, yes you can use P9600.
You'll have boost in performance.
If you want to make it cooler, try undervolting it

 

Are you sure it's different architecture? T6570 is a penryn btw... and the spc. page says "Supports Core 2 Duo, Pentium Dual-Core and Celeron processors up to 1066 MHz Front Side Bus."

 

Ok mistaken, should work if your manufacturer's bios support it, but most likely will require a bios update if there is one, since P9600 is most likely not out yet when you bought your laptop.

 

Good point. According to wiki T6570 is around Q3 2009 while P9600 came first (end of 2008). That is, apart from crazy phoenix engineers, bios should have that string right?

And what about the fsb/dram frequency? It's the mainboard that control it (cannot change in bios)? No bios update released at this time...

 

LOL that's strike 2.
Don't judge from the number (6 and 9) or the (T and P),
the T6570 came after P9600 like stated by Gremo above

yeah the ddr should be running at higher frequency 800MHz then.

 

Right... I'm proven wrong again.

Nevertheless, it's possible that the bios does not contain the identification for P9600.

As shown from their site, P9600 is not on the CPU supported list. Neither is T6570 so you will need to check with your notebook manufacturer.

Ok, thanks. Maybe should i buy also a decent pair of new DDR2 (at 800Mhz mine will run at slow CL6 )

Don't know how this works, but i can figure out that packard bell could say: "phoenix make me a bios to read all penryn (socked P) cpu according to the chipset" and not "i just want it for T6570, P7450, P7350". That way PB could sell different models to cover all market needs.

Btw you're right T6570 is not listed, PB website is a bit confusing.

Thanks both for the quick answer, great forum!

 

isn't it the default Latency for all ddr2 PC-6400 ???
Edit: 800MHz = I meant 400MHz ram frequency

 

No, for 200$ you can get the HyperX from Kingstone running at 800Mhz CL4

 

I'm not very sure about this,
but can we do it by software? eg. spdtools or thaipponburner ?

 

you can use P9600 most likely. Just make sure u have updated to the latest BIOS before installing the P9600... Also , with PM45, u should really have no problems with P9600. As for RAM , better latency/times not going to help much. Just stick with what u have. And if u want faster computer , get an SSD also...

 

Yes, you're right, but first i have to find some 2hd hard drive caddy that fits to put my WD in... 80GB SSD is too small for my needs

 

I have an Asus U81-a originally equiped with a T-6500 (GS45). I have a P9600 with no issues now. Ram is at 800 Mhz and FSB at 1066 for the CPU. I prefer the Cas5 I have in there as I can easily set the ram with SetFSB to run stable at 450 Mhz from 400 Mhz and really get the P9600 rocking at 3 GHz........

 

That's really cool! Can you tell me the frequency steps and what are your temp at idle e full load?

 

Does your BIOS have an option for Intel Virtualization Technology [Enabled/Disabled] ?. If it doesn't I would not even bother with the upgrade but 200 bucks for the P9600 is good, buy it, try it and sell it. I paid $300 for mine.

 

Yes, it has IVT. Why are asking this? 200 bucks buy it's used.

 

And you wouldn't notice a difference compared to CL6...

 

Really? There is some bench?

 

I'm talking about any real life noticeable difference. If you bench, you will definitely get a better score (but unless you're a professional bencher or have excess money, there are other and better ways to spend money).

 

also , it might help in Ocing but ur notebook most likely cannot OC due to lock PLL so not worth to get it.. Get the CPU first and then get RAM... if u need to.

 

here is stock speed prime 95, 15 minutes from idle........

The big advantages with the P9600 is the larger and faster cache. you can feel a difference in desktop etc but it altogether makes a huge difference with my camcorders HD video's and decoding down to MPG-2 or DivX for my mom's older computer and email.

 

Glad to see that's better than mine even with an higher VID (btw room temp is 21°C)... good ES one

And yes big cache should be the difference... brought it primary for .net programming (and you know how visual studio is hardware demanding), a bit of photoshop and a little gaming (were actually my slow cpu is THE bottleneck)...

Actually the user sgogeta4 was speaking about CL4 vs CL6 not about p9600 speed...

 

Ah, CL4 is only really noticable if you depend on ram for graphics memory too. There is a slight benefit to it but even less of a benefit using the larger cached Pxxx series CPU.

I don't like to run at 3 GHz as the system is more than fast enough, but here is a teaser benchmark SuperPI..........

Edit; Adding coresmark 2010, notice too my P8400 overclocked score there as well. Lastly coresmark 2010 without an OC........

 

CPU arrived, working very well cool & quite...thanks you guys!

 

The 'best way' to be sure that a machine will support a CPU change-out is to look at the parts list in the service manual.

Chances are, if a cpu is listed there, it will be supported by your machine.

You do want the most current BIOS loaded to your machine BEFORE you do the swap. Chipset and CPU socket compatibility are one thing, but the machine BIOS trumps everything.

Everything else is speculation. At your expen$e.

Considering that the higher-end mobile CPUs go for $150 and up on ebay, it pays to be sure/safe.

 

u might want to now get some DDR2-800 RAM... ur DDR2-667 RAM might limit u now that u have a 1066MHz FSB... also OP , u might want to undervolt for it to run cooler...

P.S : how's the riva tuner thing happening?

 

Sure, but service manually are usually are only for "popular" models. Packard Bell actually does not sell in US at the moment, that is finding a "leaked" service manual for my notebook is quite impossible. I already sent an email to PB asking for the manual, and the answer was (as expected) "only repair labs are allowed to get the service manual for your laptop". Odd...if i pay for the machine i would like to get ALL about MY machine, even service manual.

Anyway the cpu upgrade was successful Best 150€ ever spent.

I checked with CPU-ID and strangely ram is still running at 667Mhz. As in my first post you will find that spd says it supports 800Mhz at 6/6/18/24. Do you think that buying a branded quality ddr2 ram will fix the problem? Or is because the mainboard can't set the right multiplier?

Did not tried the driver version 186 to check if driver is the problem... still have no much time

sean473 do you know if P9600 (quite old cpu) is fully recognized in CPU RightMark Utility? Or there is a best free alternative (apart from cpu genie)?

 

I have the P9600 running and the memory is at 800 Mhz with no issues. The PM45 and GM45 have no issues there. So long as it is already cool and quite I wouldn't bother with things like RMClock etc. as they say "if it aint broke, don't fix it".........

 

So the problem is the ram itself? Should I change it?

 

your ram is not a problem. the chipset adjusts to accommodate slower than nominal ram.

the problem is whether or not a hot (speed and temps) cpu will actually run in your machine. even if it does, the rest of your machine will be presenting so many bottlenecks to a faster cpu that a great deal of your $$ and labor will be spending it's time in wait states.

 

Wait... the new CPU is ACTUALLY running on my system, the problem is ram is working at 667Mhz instead of 800Mhz.

And no, P9600 run cooler than previous T6570 (TDP 25W vs 35W).

 

OP , the problem is not with ur CPU or RAM.. they're both running allright... it just is that orginally , having a 800MHz FSB CPU , u didn't need 800MHz RAM too so to save cost they used cheaper 667MHz RAM.. now with a 1066MHz FSB CPU , its better u get new 800MHz RAM... so basically , ur RAM has no problems.. its just old 667MHz RAM which can only do 667MHz unless u overclock.

 

Here is my CPU-z info with DDR-2 800 memory.......

 

My RAM is running at a similar speed as TANWare but at 399MHz Since i have 6-6-18 clocks... basically u have 667MHz RAM and u need to get 800MHz one...not really but better to get it.

 

Yeah check if the computer BIOS would accept the CPU first. Sometimes even if a certain CPU isn't officially supported, the designation number can deviate a little, like putting an X9000 in a ThinkPad T61p, it can be done, it just wasn't officially supported.

 

My U81-a officially does not support the P8xxx or P9xxx CPU, but they both seem to work fine. I had the two CPU's already so no money lost in trying them out other than the lost TIM.......
