upgrade from p7350 to T9900

p7350 that I've currently is the worst proc in its line, but Core 2 Duo T9900 was the best few years ago.

I'm thinking to upgrade cpu of my HP hdx16 instead of replacing it... I love awesome screen too much.

But the problem is that my laptop is 2 years old, it gets very hot, and with new proc it will get even hotter right?


Since they both use same socket, I assume it will be as simple as swaping 1 for the other.

 

I would grab one from the P line

 

like P9600 ?

but it's less powerful right?

p.s. I don't care about battery life anyways.

 

I bet if you cleaned the fan/heatsink and applied artic silver on the new processor, you'll be fine as far as heat is concerned.

 

True actually reason I'm buying new cpu is that I want to clean laptop, and taking it apart is such a long process, I need to give myself a treat in form of a new cpu to make myself actually dedicate 1 day to cleaning it

I'm also planning to undervolt it. p7350 atm is running at minimum voltage on all multipliers down from 1.137 to 0.925

I've heard T series is more tolerant to undervolt.

So which one, T or P?

 

Doesn't really matter, get the cheaper one you can find. TDP doesn't mean much in relation to actual power consumption.

 

Yes, but will it be compatible with my socket? As far as I know there are three type core duos, P, T, and extreme addition. Which one is compatible with my socket? P478 its called I guess? (OEM cpu is p7350).

and I couldn't find any reasonable review of these models, which one is best to get for my lap considering that I don't care about few hundred dollars spent this way...

 

T, P, or EE CPU's will work, just make sure they're compatible models.

These are all compatible:

T9400, T9550, T9600, T9800, T9900
P8800, P9500, P9600, P9700
X9100.

 

I think I will go with T9900,

will I notice difference in computer responsiveness compared to my current p7350?

 

CPU speed and cache has no effect on computer responsiveness (ex 2.4 GHz to 2.8 GHz). Ya from a P7350 to T9900, you would notice a difference maybe in gaming, compiling but Windows shouldn't feel any more responsive.

Also a T9900 will run hot.

 

I play only wow. And it's cpu intensive as far as I know. But it plays smooth anyways with p7350.

So basically there is no need to upgrade?

you want to say that windows will run same on P7350, T9900, i3 and i5?

 

There’s a lot of stuff combined that will play a role in computer responsiveness, such as HDD, memory and the operating system as a whole. I think you’re having heat related problems, which also affects the way the computer responds. Now if you’re asking if the T9900 will be much faster at performing task, then hell yeah!

 

I think he is saying that other things on your pc will matter more before an upgrade on the cpu regarding windows running better, there is a small performance increase when you go and change the cpu within the same arch.

I have notice a great increase when I went from a P7350 (the same as yours) to my mbp 13 2011, they have (for now) the same amount of memory, the same SSD, but it feels quite snappier than the older machine. And I indeed boot faster and run my programs faster.

and I still think you should go for the P series, from what I know the HDx 16 was a hot machine the extra 10w tdp would matter

 

Well there is not much i can upgrade in laptop hdd maybe? Mine is 5200rpm

 

Upgrading to a 7200 rpm drive would not yield any gain in frames per second in games. It would reduce the load times, maybe everso slightly.

 

For sure.

I have been using T9900 for the last 2 years and could not be happier!
It still perfectly meets my needs today...

ok, I do photoshop and wow and programming via LAMP. So i guess cpu will make difference as you say...

but, p9700 is 2.6 it doesn't seem like a huge update from mine, but t9900 is 3 and it looks beefier.

In this regard, are we talking about comparable speeds? or 2.6 ghz from P is different than 2.6 from T series?

 

I’m going to be upgrading and older laptop as well, and I’m going for 3GHz +. I can tell you right now, there’s little to no difference going from 2.2 to 2.4 (my case), so I doubt you will see much gain if any unless you go for something big. If heat becomes an issue, then re-sell the CPU and go a different route.

How much are you planning on spending for the T9900? I want the x9100 so I can try to hit at least 3.5GHz without problems. The extreme processors can be unlocked, so that will make them a much more desirable processor to have over the standard core2duo processors.

 

I don't want to spend more than 150$, but it seems chip goes for more on ebay.

I found cheap p9500 2.5 though, in the range of 100$ (with shipping), what do you think? is this a good offer?

 

I saw this also:

 

That chart has no marks what the higher numbers mean...

P9500 for ~100 isn't a bad deal, but realize it isn't going to be within the 25 watt TDP with 6 MB cache and those clock speeds.

 

I just don't know dude.

You will see little to no difference from the p9500 vs the p9400 that you might get around here somewhere for $35 to $45 shipped!

So either go big or go home! If you're looking for a small upgrade, then choose the p9400 over the p9500 just because it's so much cheaper for same performance gain. If you really want to make a difference, then look into the T9600 or above processors.

 

ok I found T9600 in my price range!!! 140$ shipped. But it's used... should I pull the trigger???

 

If it is in working order and you're happy with the price you should go for it
Most CPUs in ebay are used ones any ways

 

That's not too bad! If I have to spend that much, then it better have x9100 stamped on it somewhere!

But as naton said, if you're comfortable with paying that, then do so and enjoy it!

 

well on ebay x9100 goes for 200$++

 

I paid $425 to T9900 when it was first out.
(...and sold my old CPU for $200 so the total cost was $225).

Get This T9900 And Thanks Me Later It Kicks On Everything...anyway When I Had The P7350 2.0 My Games Run Slower And The Responsivenes Was Slower To.....when I Got This Prossesor T9900 It Whas Like I Moved From A Golf 1.4 To A Golf Gti 2.0..i Think U Got The Point!!!!

 

Looks like 3DMark06 CPU scores which would be relevant to the OP's CPU intensive gaming. My P8400 OC'd scores ~2580 so up there with a stock X9100, something to think about if your looking for an increase in performance. IMO though, to see a noticeable (not slight) difference the new processor would have to be 50% or more quicker in processing (not always about pure speed). Of course you could OC the new CPU to get even better results if your laptop is up to it.

The yield mostly determines binning. In other words the P9500 will run more efficiently for the same frequency as the P7350 so the P9500 can be clocked higher and still stay within the 25W TDP even with the extra cache.

 

I just got my T9900 SLGEE from ebay and I did swapped my cpu of my hp pavillion dv4-1162tx from P7350 to T9900 SLGEE, put silver actic compound on it, put a very thin heatsink on the South Bridge chip, cleaned everything up, put everything back together, switched my laptop backon, booted OK and noticed a faster boot performance but when I ran some applications like media player watching movies while monitoring the activity of my CPU through CPU-Z, my laptop gone crazy as the fan went noisy, the movie was lagging and then suddenly shut itself off. I switched it back on went to BIOS, couldn't find settings for CPU as I believe my Insyde BIOS vF.66 advanced settings is locked by the manufacturer? Dunno what to do now should I get my old P7350 back on the track or seek a solution to it?

 

What was the CPU temperature?

 

Found the problem my GPU temperature is going nuts when watching movies its straight away going up to 80 - 120 degrees that's why it shuts itself off. Can't do anything as my BIOS locked to manipulate the cpu.

 

cpu temp was only 22 - 30 degrees when watching movie it was just my gpu temp whos going crazy
