hp dv9830us T5550 to x9000

I'm looking to swap my t5550 for an X9000 in my hp dv9830us(dv9700). I've searched some about the topic but still have a few questions.

First I read that I would have to have a custom BIOS made for it. Is this necessary to run it or is it only needed if I want to overclock it?

Second, I read that there would be some heating issues. Are there any aftermarket fans that would fit? and/or would a heating pad be sufficient? or possibly undervolting be enough?

Is there anything else I would have to take into account?

I really like the specs on the X9000, but would an X7800 or a good core 2 duo be better suited for this laptop? Thanks

 

Its not really recommended to upgrade the CPU to a notebook that never came out with it due to the lack of cooling power.

The custom BIOS is only needed to unlock the OC multipliers. No aftermarket fans for HP's, pretty much for every other brand too.

If you use AS5 and Undervolt, it should be sufficient enough to cool the CPU. If not then you will need to underclock it by a multiplier or two.

The X9000 is better and cooler than the X7800. Try and purchase a non engineering sample x9000.

 

Thanks for the information.

So a custom BIOS is need to unlock OC multipliers, does that include underlocking too?

An engineering sample has the prefix "ES", Correct? So what is a QS, and are they good?

I will use the AS5 and undervolt it. But if I want to cool it a little more, are there any quality cooling pads that you would recommend?

 

your system does not have a bios which supports overclocking/changing the FSB.
ES = Enginnering Sample
QS is for quad cores, which is not compatible with your system.

I wouldnt push your system with a X9000, because I dont think your Bios is going to support it.
I think you should look for a T9300/T9500 processor, because they will most likely be supported by your system.

Arctic silver is a good thermal compound, it is much better than any pad.

Lets use this Core 2 Ex. from ebay for example.
Can't post a link yet, but the item number is 110318058979
The seller says it's a X9000 QS Q174.. 2.8ghz Dual. However after looking at the ebay ad some more, I see it says ES all over it. So that would mean it's an engineering sample, right?

I guess, I could go with a T9500, not TOO much difference. I'll just get a few more opinions before I choose.

I'm definitely going to use the AS5 because its cheap and easy. But I'm saying for additional cooling, are there any quality pads out there?

 

well than the stepping is QS
here is the link to the cpu you are looking at:

For $530 I think you are really wasting your money.
Pick up this guys T9300 for $220 and you are set.
The jump from 1.83 to 2.5Ghz will be very noticeable. The difference between the T9300 and the X9000 is not so noticeable, so I would save your money

Spending $500 is way to much for the performance difference.
I am sure you can find a T9300/T9500 for $200 on ebay, which will be a great upgrade.

I think the seller is using QS to denote "qualification sample", there is clearly an ES stamping on the processor label and that does in fact denote that it is an intel engineering sample. They're generally sent out to reviewers and manufacturers to test upcomming cpus before public release. The stepping is C0 for that chip according to the cpuz in the auction.

 

Void if overclocked lol

Revision C0 isnt bad though.

I suggest going with the safe route and just purchase a T9300 as ktron said.

 

Most of the cpus I see are ES. But I found this T9500(also has T9300). It looks genuine.

Opinions about this one?

 

Id contact the seller for confirmation. Some of the chips he sells are Retail and some are ES like this x9000

 

The seller does not even know his own product. The T9500 is 2.53GHz.

 

Greg, get some sleep
The T9500 is a 2.6Ghz processor
You are mistaken for the P9500, which is 2.53 GHz

that ebay link doesnt seem like a bad deal. Just contact the seller and see if he is legit.

Eh, he just messaged back and told me it was an ES. Still not too sure what I should do at this point, but I'm not in a hurry, so I'll keep looking til I find something.

 

Okay guys, after some looking I'm going to go with a T9300. Since I will have some extra money, is there anything I can do about my graphics card(I read no but figured I could ask about this model specifically)

 

Good processor choice,

unfortunately you cannot upgrade the graphics card. Actually I think almost every Hp does not have an upgradeable graphics card. Only a few workstation Hp's have graphics upgradeability.

Unfortunate indeed.. I guess this will be the best I can get this PC.

Anyway, Thanks for the help guys.

 

Anything from a T8300 up would be a great boost over a T5500

 

Okay guys, back for one last question. So finally got the cpu and installed it.

Since I'm looking for ways to cool my gpu down, I was thinking about using artic silver on it also. Apparently it uses a thermal pad(Papery-aluminum sheet pasted to the heatsink). Would it be better to remove the pad and apply artic silver or leave the pad on as is? Thanks

 

Clean it first and apply AS5.

EDIT: Wait how thick is the pad?

 

If it uses a thermal pad you run the risk of not making contact and having worse temperatures.

 

I'm not sure the exact thickness but it's about the thickness of a piece of paper.

Yeah, that's what I'm wondering.

 

Oh thats not a thermal pad, thats just foil that acts as a thermal pad. My Compaqs CPU had this, i took it out and applied AS5. I suggest you leave it though and just apply AS5 on top.

A real thermal pad is about 1mm thick and its made of spongy stuff. (which is a horrible heat conductor)

 

Oh ok, Right now the foil is attached to the heatsink. So should I put the AS5 directly on the gpu OR peel the foil off the heatsink, put it directly on top of the gpu and then put the AS5 on the foil?

 

Still not sure what to do. Should I put the as5 on top of the gpu or on top of the foil?

 

Always apply it on the chip, never apply it on the heatsink.

If your still under warranty, then i suggest you keep the foil.

Just making sure... The foil should be paper thin (maybe a little thicker than usual) and the GPU chip should have left a pressure mark/imprint of it on it.

I personally took the one i had out and temps are fine.

 

Right, its paper thin like a piece of aluminum foil. The foil is actually like a tan colored pad with an aluminum square in the center of the foil, the size of the chips heat dissipator. The whole foil is the size of the gpu itself with the aluminum square in the center. And yes it left an imprint on it. (it's NOT like the thick foamy pads on just about everything else)

I'm not sure how my warranty is anymore after replacing the cpu and AS5 on it, I'd think that would void it.

 

If you didnt find any thermal paste beforehand, then HP used the foil instead of paste to probably save costs.

If it really is paper thin like alum foil then you can peel it off and use AS5 instead.

Make sure to only apply a thin layer of AS5.

You can usually still send it in for warranty, depending on whats broken. You just need to put back the stock cpu. I doubt they will look that far.

 

I don't know how relevant this will be to your upgrade, but when I upgraded to a T9300 from a T7500 I didn't notice much of a difference in performance. Shortly after this upgrade I got a bug and I did a recovery, this recovery got it running super quick. So if you feel as if it's not running as you expected, this might be the fix.

 

Ok, thanks for the help, flipfire. I'll hold on to the foil until my warranty is up in a few months just in case, and I'll replace it along with the stock cpu if needed. Thanks again.

S_P_Q_R - Thanks, I reset to factory settings before hand because I wanted to start fresh, so I hopefully I'll be good there.
