CPU Upgrade from P7350

Hey guys, i want to upgrade my HP DV5-1016tx Laptop's processor from P7350 to "something really fast".

I'm using F.11 BIOS. It has PM45 Chipset. I want a quad core basically (for my software requirements like rendering, etc)

I'm learnt from net that P7350 is placed on a P Sockets. p7350 is 25W and if i do replace with a processor of high Watt capacity, do i need to change anything else ??

I don't think i7/i5 fits on socket P .. i think only XQ9XXX is a quad core which fits on Socket P. And i would like to know if i'll face any heating issues. Or any really fast processors as well would suffice my needs.

Running on DDR2 800 MHz (2+2).

P.S: Also overclocking 9600m GT DDR2 to stock 9700m GT DDR2 (not sure if ddr2 exsits .. but something like that xD )

 

This is all assuming you actually have a socket and it doesnt happen to be soldered on.

The ASUS G50's while chipset compatible were not able to run Q9000 and other Core 2 Quads due to no support in the bios. Its also hard to say what Dual core support is there for any laptop. A good guide is looking at what the laptop was available with from HP at the time it was made.

I changed from a P7450 to a T9600 on this ASUS without any issues and something similar might be doable on a socketed HP.

 

You can only use dual cores with Dv5 and Dv6 series... as far as i know , T9400/T9600 should work.. may be abkle to use T9800/9900... but not worth it.

As Clutch said, not all PM45 mothboards support quads. Sometimes the manufacturer puts that limit in their boards. I would suggest getting a fast dual core, like the T9600 or T9800. Both can be found on eBay for decent prices.

 

Hmm, i asked the service center guy if it was soldered, he said now, i even read that P and T are not soldered, i can double check it.
I guess i should check the BIOS updates for quad core support .. Wouldn't x9100 be better than T9800 ..
I'll check with the HP dudes ..

 

T9800 would probably be cheaper, mind you the X9100's unlocked multiplier is useless unless your able to manipulate it with SetFSB or another PLL based overclocking app. I know your bios doesnt support overclocking it. So your basically stuck at 3.06 Ghz a slight bump over the T9800 and not to mention they run alot hotter.

 

hmm .. i don't plan on OCing processor, rendering usually take hours and it migt fry the processor if i do OC. Right now just the P7350 hits 80C when i'm rendering -.-

Just check on CPUz and the socket type is P and and FCBGA socket are soldered due to ball grid array something

Well the P7350 thermal max's at 90C so 80 is hot for it. Where as the T9600 doesnt self protect until 105C. Mind you the DV5 doesnt cool as well. But i aint skeered on myne. I use kerkythea for hours and days long renders without fail overclocked to 3.3 ghz. My ram is actually my biggest overclocking issue.

The T9900 was supposed to have X9100 clocks, the X9100 commands a huge price because of its unlocked status.

 

No BIOS flash or chipset upgrade would make a PM45 chipset to accept C2Q?

 

The dv5t was never sold with quads; only the Core 2 dual-cores. It was also not sold with the Core 2 Extremes so I caution against putting in an X9100 -- it has a higher TDP and will likely produce too much heat for the cooling system to handle. The dv5t has a poor cooling solution to begin with (I own one).

You could go up to a T9900 theoretically. I suggest sticking with the P8000/P9000 series processors as they run a bit cooler. Consider a P8700/P8800/P9500/P9600 -- whatever is cheaper. The P8000 has a 3MB cache and the P9000 has a 6MB, but the extra cache makes no difference (I have both and even synthetic benchmarks show no difference). The P8000 series CPUs should be cheaper. I have a P8400 in my dv5t.

FYI there are cheaper and easier ways of improving the performance of your computer. Consider upgrading the hard drive and adding more RAM. Also upgrade to Windows 7 if you haven't already.

 

Yeah, I already have win 7 and 4gb ram. I'm buying a notepal x2 as well. Zalman nc2000 was my first choice, but i couldn't find one in india.
I don't think HDD would make any difference in rendering.

I want a quad rather than higher clock speed dual core. Yet to call the HP dudes, will keep you guys posted. I'm looking at q9100 right now ..

 

lol calling up HP with some crazy upgrade like that will only get you an earful of how that might void any warranty that might be left, and they will say no upgrade works. Good luck though!

 

Ok, gotcha.

But like I said, the dv5t was only ever offered with processors rated for a max of 35W TDP; the quads and Core 2 Extremes are much higher than that (45W+). I doubt the dv5t heatsink will be able to handle it; it is barely able to handle the higher-clocked duals. The fastest processor it was sold with was the Core 2 Duo T9600 (2.8GHz/6MB cache) and that ran very hot (see the dv5t owner's lounge in the HP forum; it got 80-90*C under load).
To my knowledge, no one has tried a quad-core in a dv5t before. It's a risky proposition due to the heat issues as mentioned and the possible incompatibilities; as someone said earlier, only certain notebooks support them.

 

I think a P9600 would be your best choice as mentioned before. They run for about $150 to $170 on ebay. Please make sure you're not buying an ES chip, request an actual picture of the chip. It should say SLGE6 ... AW ... something.
I tried a QX9300 and it did not POST (I have the same chipset as yours). I don't know what my expectations were but I had one available so I said why not. Then I tried a P9700 for two months and it was okay except fan noise and battery life so I settled for a P9600.
P9600 responds very well to undervolting. I dropped it to .900V and it's stable. It should run at 66C - 68C under full load.

 

Here's Intel's own info on their CPUs. If you click on a specific proc, it shows you what socket it will work in. That's not a 100% guarantee it will work though I would say just to keep it simple use the P8700.
EDIT: http://ark.intel.com/ProductCollection.aspx?familyID=26548&MarketSegment=MBL

 

What is the difference between ES chip and SLGE6 ... AW ... something ??
I don't care about battery life. P7350 is 25W right, then if i replace it with a processor of 35W or 45W .. do i need to change anything for the increase in the Watt ?? Like the adapter or something ??

Did the QX9300 did not work due to BIOS or something ??

I believe currently the performance gain i get through P9600 or T9900 is approx 100% .. that is 2x.

But i'm right now doing this to get atleast 3x to 5x .. I'm sure a quad would help me with that .. I'm talking about the rendering time .. not gaming !

 

ES stands engineering sample, and can be missing features, thus most people stay away from them.

If you put a 45 watt quad in, either is won't post, or it will overheat in like 20 minutes of doing anything CPU intensive.

You best bet would be a P8700, P8800, P9600, or P9700. Those are all 25 watt chips. Basically the quad is not an option for your laptop.

 

If you are doing lots of rendering work and the rendering time makes you go crazy, a high clocked dual core like p9700 will help, but not to the extent you will be satisfied. You will really need a powerful quad processors for that kind of work, if you could, I suggest you build up a desktop with a powerful i7, no laptops with dual cores are going to be near as efficient as that when it comes to rendering, really, even if you have a dual core like i7-640m.

But if desktop is not an option, and you are limited to the laptop you have right now, then get a t9900 or x9100, or P9700 if you are really worried about heat.

 

Well he could try undervolting with RM Clock...but a good point if the laptop didn't offer quad cores more than likely the cooling system cannot cope with the extra TDP.

 

Hmm .. i thought it might come down to desktop .. hmm ok I'll try any of the 9xxx series in T or P compatible with my chipset. I hope its worth it :|

I was gonna buy a Alienware Aurora but .. hmm .. i thought i could buy it after a while (.. when i'm actually working) .. and till then just upgrade my laptop to quad and enjoy life xD

 

TDP doesn't mean power consumption/heat output. An R0 or E0 stepping quad of 2Ghz can probably be undervolted considerably and consume about the same or possibly even less power than one of the stock higher clocked duals. Also the TDP rating of the X9100 processor is only there to give it overclocking headroom. It doesn't magically consume more power than a T9900 when running at the same frequency and voltage. Also look into an E0 stepping E8335 or E8435 processor. They can be cheaper than their T series equivalents.

 

Wouldn't undervolting reduce performance or something ?? other than heat ..

 

No way jose.

 

If it's undervolted improperly, sure you get random BSOD or freezes. You have to find a stable voltage which means alot of trial and error.

But if you find a voltage that runs prime95 8+ hours and doesn't choke, then it's free heat reduction (or in some cases none)!

 

As noted you are asking too much from your current laptop, even with a CPU upgrade.

My dv5t has a P8400 Core 2 Duo processor (2.26GHz/3MB L2), which is fairly modest. It gets in the 60-70*C range under load. And people with higher end duals like the T9600 (2.8GHz/6MB L2) get in the upper 80*C range. There is NO WAY this system will be able to cope with the heat produced by the quad, especially one running at full tilt for extended periods -- and that's assuming it even boots at all.

 

I dont know if any laptops came with x9100 installed

It seems like a very desirable cpu for a lot of people, me included with my g72.

But the price is just too high still. There was never a used market for this cpu so all we are getting is taiwanese overstock

Its still at 230 on ebay. Might even go up as its the best cpu for a lot of machines.

Nowthe t9900 on the other hand, it was in laptops and there might be some used in the world for cheap.

 

Yeah, that's probably why the x9100 price is still quite high even it's an older dual core, a lot of pre-i core laptop owners want them as its the best they can put into their laptops, plus you get the option to overclock, which could easily make it rival with the high end dual core i5/7.

 

True. I upgraded my CPU from P7450 to T9900 and I do a x264 re-encoding a lot. It definitely improved the speed (about 36%). But, the dual core is just not powerful enough for video rendering/encoding. I use my i5 760 desktop for that kind of job.

Temp actually dropped by 7~9 C w/AS5 though in my case (ASUS G60).

 

Alienware, Sager, and Clevo put the X9100 in their laptops.

In that pic you can see why my laptop can run a quad, look at the thickness of the heatpipe, the one on the GPU is what you likely have for your CPU. Also the surface area of my heatsink is likely greater.

Also you have to think about your power delivery, I have 3 dedicated phases supplying my CPU, you will at best have 2, at worst they will be shared to feed other componants.

 

LOL, I undervolted my P7450 to the minimum .900 volts and then overclocked it to as far as the ram would let me. Always ran into overclocking problems because of ram speed.

My T9600 undervolts a little but if I overclock it I have to have it at stock voltage. Every single chip is different but P series tend to undervolt better.

In theory undervolting actually slows electronic switching a very tiny bit, but you would never be able to find a difference, when you do you just got a blue screen of death.

 

OK, this is completely theoretical right now. If my MainBoard BIOS is HP right now. Is there a way to reset it to the original stock one .. like intels' or something.

I thought, if i could change the existing PM45 with a new PM45 and i could add a new graphic card as well. And i could upgrade the processor. Yes yes .. cost is very high .. i'm just wondering though, If its possible. Of course it wouldn't be HP in anyway after that.

Yes i would be changing MainBoard + Processor + Graphic card + the heat sink. Hope they still fit inside

Zzzz .. i guess i should just buy a desktop -.-

 

No, you cannot change the motherboard. It is specific to the dv5t. There are no notebook motherboard standards like there are for desktops; they are 100% proprietary. The graphics card is likewise impossible to upgrade.

And yeah, you should just buy a desktop.

 

Laptops typically dont have a reference bios. Reference bios's rarely work in desktop boards as it is. Answer is no from me.

HP designed the board from a reference, to fit the laptop and modified it for the equipment they planned to use. I am pretty sure there isnt a bios for it other than hp's own reference bios which they arent gonna give you and is probably pretty incomplete.

What board are you gonna find to fit a laptop that has all its board connectors in very specific places?

Yeah buy a desktop.

 

Hey guys, found this post on the forum.

http://forum.notebookreview.com/asus/539065-m70vn-q9100-need-help.html

Any Ideas how he extracted a copy of BIOS ?? I want to try it with my BIOS as well.

 

Anyway, Thanks for all your help guys(/gals .. if any ) !

 

Ya but you see the type of stuff you have to contend with.

He bought a q9100 which is supposed to be compatible. However theres nothing he can do

The microcode is not his problem at all

Its the same with my laptop, quads just do not work theres no solution.

 

Hey clutch, what software did you use to overclock your t9600 ?? I am guessing its SetFSB as you mentioned you ran into issues with ram OC .. Which PLL did you use for it ??

 

The PLL is specific to the motherboard which uses a clock chip that u need the PLL for. ICS9LPR604AGLF is what the G50 uses.

 

Since you said that your ram is an issue in overclocking, isn't it possible to change the FSB RAM ratio to lower the frequency of the RAM and you can still overclock the CPU.

If T9600 bus speed is 266 and multiplier of 10.5 by stock and a DDR2 ram of 400 Mhz (PC6400). Bu increasing the Bus speed from 266 to 319.2, you get you CPU max frequency at 3351.6, but the RAM is now at 478.8. So the FSB RAM ratio is 2:3. If you change the ratio to 4:5, then the the RAM frequency would fall back to stock 400 Mhz but you CPU will still be at 3351.6 MHZ (~3.4 GHz)

Right ? Is there a way to change the FSB RAM ratio ??

 

Yeah buy a desktop with an overclockers motherboard ? or an alienware... lol
