Compatible processors for DV5-1235dx

Was getting ready to buy a new laptop soon. Had a client contact me to pull data off his DV5-1235 and put it on his new laptop. He had dropped the laptop and smashed the screen. When I was done I offered to bill him or take the broken laptop and call it quits. He gave me the laptop. I have it all apart already just waiting on the replacement screen. Since i don't have to buy a whole new laptop I have some extra cash to throw into some upgrades for this thing. Thinking a C300 ssd but more importantly thinking about upgrading CPU. It has a t6400 presently. I looked through all the dv5-12xx and 13xx series laptops and they all seem to use one of the T6xxx processors. Obviously 200MHz to go to the T6600 is not worth the trouble. I'd like to go with something faster with more L2 but I have been totally stumped to this point as to whether the laptop will actually recognize something outside of the T6xx processors.

Anyone who can offer some advice on the issue? Will the system support 1066 FSB or just 800? Ideally would like to go to one of the 9xxx and try to get as much as possible out of it.

 

If you have Intel Graphics or can look in the device manager and see what your chipset is....

GS/GL40 = 800MHz FSB Max. = Intel T6xxx/T7xxx/T8xxx/ and... T9300, and T9500
GM/PM45 = 1066MHz FSB Max. = Intel T and P series will fit with BIOS update.

 

I'll have to piece it back together enough to check that out. Thanks for the info that is exactly what I needed.

So assuming that I have the 45 variety would I be better with a P or a T? I see the P has a 25w TDP vs the 35w of the T any other differences? At equivalent clockspeeds do they perform the same?

 

They do perform close to the same depending on how well binned the processor is. However, the P series processors are more expensive for the performance you get. And the battery life may be slightly better.

AFAIK, the Dv5 comes with a PM45 chipset. You SHOULD be able to put any T series or P series processor - extreme edition processors may be possible, but with a notebook that already runs hot, I wouldn't recommend it. Plus, the 45W TDP makes it a little difficult to tell if it will work in that machine or not.

However, do not take my word for it that it has a PM45 chipset - always verify it first.

 

i'm quite sure all DV5t's have PM45 or GM45 chipset so try T9400/9600/9800/9900 for CPU upgrade.. T9600 will work for sure from what i know about Dv5t as it was one of the options for it.. 9400 will also work but i'm not sure about 9800 or 9900.. P series CPU's will also work but get only P9500/9600/9700...the others are too weak.

 

Well then as long as the chipset verifies I think I'm gonna go for the P9700. Gonna cost about $100 more than the T9600 but the 28W TDP looks good for cooling purposes.

Does the TDP determine power consumption or is it just heat dissipation? Would it be reasonable to expect longer battery life by going for the P over T?

 

Not worth getting a P9700.. A T9600 is faster and although its TDP is higher, it really doesn't use much more power.. by undervolting ( which is perfectly safe), u can reduce power consumption and u the power consumption much lower.. and actually get much better battery life than a P9700... the P series is just made to rip off u by intel.. i have a T9400 running at 1.125V other than stock voltage.

 

Interesting. Thanks for the heads up. Not sure that I have the ability to undervolt in bios on that thing. Like I said I'm waiting on new screen so I've only used it with an external monitor to make sure nothing else was damaged before i made that offer. I'm sure there is a way but I could only get the monitor to kick on once Windows was booted so I didn't get a chance to peruse the bios though I can't imagine there are that many settings on a HP.

In that case I might as well go T9800 as that would still be cheaper than I was willing to pay for the P9700

In searching I've only found one article that mentions the chipset here it says Mobile Intel GM45 Express Chipset so I've got my fingers crossed.

 

By all means, if you can get the T9800 for cheaper than the P9700, go for it! You won't be disappointed. The T-series has a 35W TDP, but rarely do you have both cores going 100% taxed. In a lot of regards there's not really much different at all between the P9700 and T9800.... Small TDP difference and 130MHz...

 

Cool then I will go ahead and order T9800 and hope everything goes smoothly. Thanks for the help in figuring it out guys.

 

Like i have said before , Dv5t uses GM45 or PM45 chipset which support these CPU's... as for CPU undervolting, u don't need options in BIOS to do this.. u usually do it using software and there's also a guide to do it... when u get it , tell me and i'll show u how to do it.

Also the highest processor ever installed was T9800 in the special edition version.

Bios may not properly recognize anything higher.

 

Well I'm gonna start at T9800. If it doesn't work I can just ebay it and should get most of my money back then I'll move down a step each time. Hopefully I am good on the T9800. By most indications it seems like it should work and I don't mind taking the risk considering I can just resell the chip if it doesn't work out.

 

T9800 will work as that is what HP sold it with (special edition). Meaning there is BIOS support for it.

Incidentally, the P series (e.g. P9700, P9600) work also.

 

Yeah I was originally checking out the P9700 but from what people said earlier in the thread it isn't worth the extra money to get the lower TDP of the P9700

 

I did suggest the T9600 first.. from the hp service manual , i have read that it should work for sure.. try the T9800.. i don't see it not working but T9600 will be next logical step.
