HP/Compaq :: Undervolting HDX 18t Quad 9000
Oct 5, 2009
I just wanted to share my experience on undervolting my HDX 18t 1103EA, Intel Quad 9000-2Ghz, 4GB DDR3 RAM, 9600M GT-1gb, Vista x64. After reading and trying the undervolting guide (thanks to flipfire), I couldn't make rmclock to work. Anyway because Q9000 has only 4 multipliers: 6x, 6.5x, 7x and 7.5x and rmclock does not support half ones, I decided to try CrystalCPUID. It can do only three ones and I choose 6x, 7x and 7.5x. I managed to go down to 1.163- stable on all three. CrystalCPUID would not allow any lower than that, although according to Intel Q9000 lowest voltage is 1.050. Strange enough both CPU-Z and Everest show that this the actual voltage when CrystalCPUID is active. Also when it is not active the cpu works only on the highest multiplier- 7.5x. My idle temp didn't really changed- it is always around 48C-55C (no AC in my room). I tried to buy CpuGenie (10 euro is nothing for some extra life on a 1300 euro mashine, but paypal asks for registration and I don't want to register.

I undervolted my notebook to some values, the temperature did drop by quite some decent degrees, but i want to get it to the limit, what's the stable values you guys mostly got on your dv5? (im intested in those with similar configuration to mine - see sig)

Following the excellent flipfire's undervolting guide and inspired by Silvr6's experience with undervolting his dv2, I decided to give it a try and...I was able to increase the battery lifetime from almost shameful 2h 25 minutes to 3h 30 minutes for mpeg 2 play, or even to 4h 20 minutes (light browsing and lots of reading). So, you get at least 25-30% more battery lifetime. This makes me like my dv2 a lot more!
Perhaps, it's the noted AMD's tendency to overvolt their CPUs, perhaps something else, but I was able to get the following 100% stable (in my case) voltages:
4.0x-0.6875 V
4.5x-0.7125 V
5.0x-0.7250 V
5.5x-0.7500 V
6.0x-0.7750 V
6.5x-0.8000 V
7.0x-0.8000 V (yes, its 0.8V again)
7.5x-0.8250 V
8.0x-8.5000 V
these voltages are stable for my particular CPU; yours might be slightly lower or higher. For example, Slvr6 was able to get a bit lower with 4x 0.675 V. Read the undervolting guide!
But I hope that the table above will encourage you to try the undervolting (btw, unlike the overclocking its 100% safe), since the benefits for dv2 and AMDs neo are so dramatic!...........

I've just got my 8540p and I am looking for some undervolting tool for the Core i7-620M procesor and also some underclocking tool for the nVidia NVS 5100M.

I have an older HP Pavilion dv 9000, with Windows 7. I was attempting to watch a video and noticed that the sound was muted. So, initially, I tried to turn it up, but it seemed locked. It had never done that before, so after several failed attempts, the mute sign disappeared and now it's just a red x, and when I go in to check it, it tells me that there is no sound hardware installed. I tried to install a new driver from your website but it is still not working.

I just got my new dv7t quad laptop and when i turn the laptop back on from sleep the fingerprint reader is not detected. so when i go to type in my password manually the screen flickers about every 2 seconds and resets the cursor to the beginning so it makes typing my 16 character password a , i usually have to just restart.
Also i ordered a bluray player and installed that into my laptop but the hp mediasmart software wont play the movies. i ended up getting a trial software for 30 days but i dont plan on spending another 50 bucks on software when hp should have software i can use with this laptop.

How does the 1/6 GHz processor stack up against the more traditional core duo? Is it roughly equal to a 2.53 GHz processor? I love windows 7 and might trade my Macbook Pro for one.

This model has customized & quick-ship option.
I notice the customized version is fitted with Geforce GT 320m - For i7 processor (no other option), while the Quick-Ship model is fitted with GT230m WITH Physx.
I've heard about Physx before, and I always think it is another component bought separately (at least for PC desktop 1-2 years ago). So, is this Physx processor always present with all Geforce GT230m & 320m series, or does HP actually fit this additional processor as a bonus ?
I look on NVidia's technical specs for 320m & 230m, and Nvidia specifies that they are both Physx-ready. What does "READY" mean here ? Ready to be fitted with an optional Physx feature, or does it mean both have already integrated the Physx into 320m & 230m ? ...or do I misunderstand something ?

Realizing that my computer is now a little over 2.5 years old, I had a little time to think about whether I should even think about going over to a brand new notebook. Given the specs of new notebooks these days (and a lot of people know here that I spend quite a bit of time at the HP website/FTP), I was wondering what everyone here thinks about me going for a Quad Edition notebook.
In case you're wondering, I use my dv6500t notebook extensively mainly because I am a UCSD Computer Science/Engineering student who does a lot of activities on the computer both casually and for work, for a good portion of the day, everyday. If I get a new notebook, I plan on using it extensively as well.
The specifications for the dv6500t that I currently use is listed in my sig. It additionally has a 12-cell battery which at this moment can only charge up to 58%, and a rather broken left TouchPad button. Warranty is pretty shot at this point, since I had the 1-year standard (which I have no regrets with).
Now, the Quad Edition notebook that I was specifically looking at was the pre-customized HP Pavilion dv6-2190us notebook:...........

I will be receiving a dv6t Quad edition soon. I am planning to replace the original HDD with a SSD. The original HDD will go in a external eSATA enclosure.
Questions/comments:
- Are there any step-by-step guides out there for replacing the HDD?
- I have read in forums that doing a fresh install on SSD is better than cloning your existing drive. Is that correct?
- In case of any issues with the installation on SSD, I can always put the original drive back in.
- If I dont delete the MBR on the original drive, will it create an issue in the external enclosure along with the new MBR on the SSD?

I guess I spoke to soon about my system being perfect (except for the hard drive cover issue that has now been corrected.)
My keyboard is kinda strange. The keys from the middle of the keyboard, all the way over to the right are good and feel solid...even the housing the keys sit in is very solid. HOWEVER...
From the middle of the keyboard all the way to the left side of it when I type the housing that the keys sit in is not solid...it has 'flex' to it...and is actually quite loud when typing in that area. Is this normal or do I have a bad keyboard? God I can hear it now "please return your system to HP to replace your keyboard"...
I'm sure it's very easy to remove it and change it but they will insist that I send it in. Why can't they be more like Dell when it comes to parts that are easily user replaceable?

I have two power bricks for my notebook (I bought a second one at the time I placed my order so I would have a spare for traveling, etc.)
One of the bricks gets way hotter then the other. I don't understand why, they are both 120W adapters. I can't help but be paranoid that something is wrong with the one that gets really hot and I'm afraid to use it. I mean why would one barely get warm and an identical second one gets hot?

i recently bought this laptop and im running stress tests on this laptop w/ prime95 and told by a fellow board member(who has been of wonderful help) that they detect issue w/ my heatsink mounting/paste for my quad core qx9300. it was stated that thermal throttle shouldnt happen until temperatures into the 100 celsius range on a laptop?
1) i start the test and all 4 cores are steady running through tests
2) after 3 min, the first 2 cores max out at 91, 90 celsius while the last 2
are 89,88. The first 2 cores start going down in temp to about 76, 75 and
never complete another test while the last 2 cores are 85, 86 celsius and
run through an additional 8 tests afterwards.
can anyone give more feedback or possibly try these tests also? i run 64 bit vista also.

how to do a clean install and to backup the swsetup folder and to create a set of restore disks just for the hell of it and all of that...so that's not really what I need assistance with.
I was wondering if someone wouldn't mind listing all of the drivers & software that I need to reinstall after the clean OS install is done so I don't miss anything and also the order in which they are to be installed. Why am I asking this? Because this is my first HP, I've always had Dell's before and I realize HP has some other software for like the hard drive protection and stuff so I'm not very familiar with it.
I wasn't able to order my system with a blu-ray drive as their is a global shortage and it was only being offered on the DV8T...which is just way to big for me. HP says they put comments in my file/account that state when they get blu-ray drives in that they will either swap the drive out for me or give me a new computer because of the inconvienence. Now I'm not holding my breath on that but in case that doesn't pan out...is there anyway I can buy the HP blu-ray drive myself from somewhere online and then get it swapped out on my own? I would of course want it to match my machine, I wouldn't want to just get any drive. Also my video card is the GeForce 320M but from what I've read this supports blu-ray as well, yes?

my plan is to buy an 8530w and swap out the cpu for a Q9100 Quad Core. Anyway, is there special cooling needed for the quad core? I asked only because i noticed that if I tried to add a quad core on the HP website it requires a 'special' graphics card. This got me thinking that they might have added something for the quad cores that they leave out of the normal ones.

Is it normal for the power brick to get hot? When I say hot I mean, it's so hot I'm afraid to leave it plugged in and go anywhere. I just got my system the other day but really haven't messed with it so far (except for making sure everything was up to par.) Today I started getting into everything, clean install, etc and I noticed like after 10 minutes of it being plugged in (120 watt brick) the brick was so hot it felt like my heating pad on high. I've never experienced this before, is this normal?

every time I change the volume it goes into the separate volume popup window and whatever else I'm doing gets minimized if it was fullscreened, it's really annoying. How do I turn this off? I've been told by a HP custom service guy to uninstall Quick Touch, but I can't even find it anywhere.
(are there any other things I can do to optimize this computer?)

Any views on the differences (and value) between HP Envy 15 and HP dv6t Quad Edition?
As far as I can see, with the maximum upgrade options selected below, for an additional ~US$1,300 all the Envy 15 gives you over the dv6t Quad is: 16GB DDR3 RAM instead of 8GB (valued as $500 difference on the Envy 15 customisation page) 1GB ATI Radeon HD 4830 instead of 1GB Nvidia GeForce GT 230M external vs internal optical drive (query whether this is an advantage, weight vs convenience) 1920x1080 instead of 1366x768 display extra 9 cell battery (valued as $125 difference on the Envy 15 customisation page) it's a bit thinner, lighter and 'prettier' What do you think? Is all this really worth $1,300? (Or if you accept the values given by HP of the extra RAM and battery, is $675 a fair price differential for the HD4830, higher display resolution and overall build?)
As a follow-up question, what do you think of these specs generally - or is it worth waiting for further customisation options for the Envy 15 (eg, the dual SSDs in RAID 0 promised by all the HP marketing) and for eventual price drop (when will either of these occur)?
The following specs / upgrade options were used for the above comparison, all from HP Direct, major differences are starred...

As most of you know there is a blu-ray drive shortage globally so when I configured my system last week I could only configure it with a lightscribe supermulti dvd/dl drive. However there is a quickship model that comes with a blu-ray drive. Is there anyway for me to purchase the HP blu-ray drive by itself and swap it out for the one I had the system configured with in the future when the drives become available again? I would want it to match my machine so I don't wanna do it with some other brand...it has to be the HP drive that would match my system

Just picked this up. Let me know if I got a good deal. I wanted to buy a Dell, but didn't want to spend over $1500 for the Studio 16 XPS.
Dell was offering the Studio with Core2 Duo and did not offer a sale on the i7 version. Hope I dont miss out on the LED LCD screen.

i just bought hp dv8t quad laptop recently. the first time i turned on, treble bar (blue horizontal bar to adust treble that is supposed to appear only when i touch that touch tone above keyboard) came up on middle of screen intermittently. everytime i run other application, this bar would come up and stops other application. i spent over 1 hr with hp tech to fix it. now everytime i turn on, this blue bar still comes up but after i adjust treble via tone control above keyboard, it disappears. tech says there is no hardware defect, but i am wondering if others are like this.

I'm trying to install:
1.) Intel turbo boost technology driver (for i7 processors) and...
2.) Intel management engine driver
I keep getting an error message telling me that my hardware doesn't meet the minimum system requirements to install the software...which makes no sense! I've already installed the Intel chipset driver and the intel rapid storage driver AKA matrix storage driver. These two must be installed before installing the ones that are refusing to install.
I called HP, got India and the guy insists just because the driver is listed for my product doesn't mean it needs to be installed. I just kinda laughed it off, he was useless.
So I did a google search on the problem and it seems a lot of people are having the same problem getting these two drives to install-same error message and everything.
any info on IF they really need to be installed and if so, how the heck do you get them to install already?
