Hp dv9740us cpu upgrade

Hello,
Please help. I have a dv9740us and was needing assistance to find out what my upgrade options are for my cpu and video card. I have a Intel Core 2 Duo T5500 Mereom (T5450, 1.66GHz), Socket P (478) and a Geforce 8600 512Mbytes. I am running the latest BIOs F.5A dated 3-22-2010. I have maxed out ram memory at 4 gigs. I'm also running Windows 7 Ultimate.
Your help would be greatly appreciated.  I just bought an hp 17" 3D ENVY and love it but i still want to keep my dv9740. I have upgraded a few desktops this past year, ie.: cpu, video, HD etc to run 3D so I'm not foreign to working with hardware. its a satisfying project.   Thank you and any suggestions would be and are greatly appreciated.

Hi,
1. The following book shows you compatibale CPU supported, you may be able to upgrade CPU to the same family even not in the list:
http://h10032.www1.hp.com/ctg/Manual/c01951704.pdf
2. From my memory, when NVIDIA recalled the 8600M cards, it had to replace the whole machines (HP) because it could not just remove the cards.

AMD Athlon 64 3800+ cpu upgrade to AMD Athlon 64 X2

Hello everyone,
First of all, I have been to cpu-upgrade.com and typed in my current (CPU)--> AMD Athlon 64 3800+ 2.40GHz (motherboard)--> ASUS A8M2N-LA (Naos) GL6.
According to the website, my AM2 Socket (940pin) is capable of upgrading to a Dual Core, Anyone know if that site is accurate or not? Any help would be nice. I need to get away from this single core.
1) Some CPU models require a BIOS upgrade, which a BIOS upgrade for this board is not available.
2) A lot of X2 Dual Cores work either using a 4400+, 4600+, and so on....
I do have a 550watt PSU installed, also I am using MSI Nvidia GeForce GT620 PCI-express 16x graphics, not using onboard.
I have read that some BIOS' upgrades terminate the onboard video, is that true? Basically, whatever I already have installed is current and up to date with all video/sound drivers, etc... If anybody very knowledgable knows for sure if an AMD Athlon 64 X2 will work in my system that would be nice. My specs below......
OS: Windows Vista Home Basic (32bit)
CPU: AMD Athlon 64 3800+ 2.40GHz
RAM: 2GB (GDDR2)
PSU: 550watt (all 20+4 for main cable to motherboard connected using all 24 pins + 4pin connector for CPU? I believe.
Sound: Realtek HD ALC888 High Definition Audio
Video: MSI Nvidia GeForce GT620 (GDDR3 with 2GB Video Memory).
Only thing I am bottle necking on is the CPU, and I would love to upgrade to Dual Core, once again, thank you for the help.

Hello @bigsnake,
I understand you are looking to upgrade your processor on your Compaq Presario Media Center SR2013WM Desktop PC. I am providing you with a link to a CPU-Upgrade thread concerning your very question ASUS A8M2N-LA CPU compatibility list. Now this is the only information I have been able to find concerning a processor upgrade for your Compaq Presario Media Center SR2013WM Desktop PC.
I hope this helps. Thank you for posting on the HP Forums. Have a great day!

CPU upgrade on Satellite L30-101

Hi, I have a Toshiba Satellite L30-101. I've upgraded the RAM successfully to 2GB (2x 1GB) but I'm finding it incredibly hard to get information on processor replacements.
The laptop has the latest BIOS on it (3.10-WIN - 19/02/08) but when trying to find information regarding whats in it I'm hitting brick walls. Firstly the site > http://www.toshiba-tro.de/biosinfo/ < doesn't have my laptop on it,
Product Type: Notebook
Family: Satellite
Product Series: Satellite L Series
Model: ? unknown
Short Model No: ? unknown
I did hope I could stick an Intel Duo in but with the ATI chipset, I'm pretty sure it wont work but again without knowing whats within BIOS, compatible.. I'm lost. The only processor I can find which may work, same package, FSB, socket is an Intel Core Solo Processor T1350 which kicks out 1.86 GHz, not a massive difference and I'm sure it can't be the only replacement option.
Could someone and staff please help me with getting hold of BIOS info and compatible processors for my laptop. The current Intel Celeron M Processor 410 kicking out 1.46 GHz isn't good enough for Vista (cert on laptop) and basic multi tasking. Its lagging way too much even after a good tune up, ram upgrade, HD upgrade to 7200RPM. I'm in need of a processor upgrade but as mention finding it incredibly hard to obtain information of which would be compatible.
Sincerely,
Gourcuff

Hello
In my opinion your attempt to replace CPU is wrong. Why? Satellite L30 is not designed to offer some fabulous performance and it is designed for everyday usage. Best evidence for this was the price. It was not so expensive.
Can you please tell us why do you want to have new CPU? Do you use some special software?
Back to CPU replacement. As you probably know mobile computers have limited upgrade options and it is related to RAM and HDD upgrade. It is definitely unprovided for CPU upgrade and it is not supported. Specific design, especially cooling system is designed for certain CPU.
Due to all this you will not be able to find any relevant info about CPU replacement.
Check please this Toshiba document - http://aps2.toshiba-tro.de/kb0/TSB9401AX0001R01.htm

Is CPU upgrade on Satellite 2410-303 possible?

My Satellite 2410-303 has Pentium 4 Mobile 1.7GHZ processor. I want to upgrade its processor to Pentium 4 Mobile 2.8GHZ. I think that it is possible because its upper models have faster processor and that is unique difference between them.
Please, help me for this question and tell me is it possible?

Hello
You will be very lucky if someone has so good experiences with CPU upgrade on Satellite 2410 but on this forum you can find very nice comments about that. I have founded just two of them but very interesting. Check it out!

Satellite M40x will not boot up after CPU upgrade test

I have an M40x Laptop. I took the CPU out of it to replace it with another to test the computer booted up fine so I shut down and took it out and put it's original CPU back in, and it would not boot. Now it will not boot up at all with either of the CPU's all. When I turn on the power all I get is a white screen for a few seconds and the laptop shuts itself back down. Both the CPU's are good because I have since tested them in other computers to make sure that was not the problem.
Anyone have any ideas on what is causing this??

Im not surprised.
As far as I know Toshiba does not support any CPU upgrades and it's not advisable to do something like that.
Its a fact that the CPU replacement on the notebooks is not easy and mostly not recommended.
The processors used in portables are connected to the system board using a process called TCP (Tape Carrier Package). This is a permanent connection method and is used in the interests of miniaturization and heat dissipation.
Did you assign the new heat paste? Its necessary and important if you want to connect the CPU again.
So possibly this is a reason for the no booting.
I think more details you will get from the service guys in your country

CPU upgrades

I'd like to upgrade a tray-loading iMac with the CPU from one of the faster slot-loading ones - 350, 400, whichever.
I'd also like to swap a 450 or 500 MHz CPU from a DV SE that had firewire into the earlier, ordinary slot-loading version, which didn't.
Does anyone know if there's any reason there would be a problem doing either of these changes?
For that matter, if the DV motherboard's okay, any reason I couldn't use the whole thing in the slot-loader? I think there's a video problem, but if that's just a monitor thing and not on the board, it shouldn't be an issue.
Thanks

you are correct, the slot loaders do not have a separate CPU card, its soldered directly to the logic board.
There are CPU upgrades available for tray loaders (don't know if any are actually still produced anymore, but they do exist), but the cost usually just isn't worth it. You could get a used slot loader for the same amount,a nd a used eMac or mac mini for a little bit more.

1.0/1.1 GHz G3 Powerlogix CPU Upgrades in Beige G3

There have been very few postings of upgrades to the Powerlogix 1.0 and 1.1 GHz G3 CPU upgrades over at xlr8yourmac. Any of the upgraders here have any experience w/ this CPU upgrade in a Beige G3? Comments positive or negative? Problems?
I'm currently running a 466 MHz CPU in a Beige MT and am looking for a little more quickness. I've already maxed out the RAM and am running a ATA-133 Maxtor HDD on a ATA-133 SIIG PCI card.

Thanks for your comments. There are very few xlr8yourmac postings for the newer Powerlogix G3 upgrades in a Beige G3, but several for the B&W G3s. Likewise, xlr8yourmac's own CPU upgrade comparison using the new Powerlogix G3 upgrade was done w/ a B&W. The problem is that the B&W's were so different from the Beige, so quirky, and in fact so different from the front to the back of their production cycle that I wouldn't rely on their results as typical for the G3 upgrades. That said, most of the B&W upgrades w/ the Powerlogix 1/1.1 GHz IBM chip were favorable.
I ruled out the G4 upgrades for my Beige based on the long string of horror stories of those early adopters of G4 upgrades for their Beige G3s. They may have solved those problems, but I decided some time back, based on various web discussion threads, that G4s and the Beige just don't live and play well together.
It is true that the 66 MHz buss is starting to be a noticeable choke point. But, for the most part, speeding up what you can speed up, compensates for that problem. No, it can't make it into a new machine, but a used Mac at 933 MHz on ebay is going for almost $1K, and I can approach that performance for a lot less additional investment.

HP8000 elite SFF; what CPU upgrades are available

I've just bought an HP 8000 Elite SFF desktop (WB717ET#ABU) with a Pentium DualCore E5400 CPU running at 2.7GHz.
I was wondering what CPUs the Motherboard (Rev 0C by the looks of it) could accept in order to squeeze more performance out of it (and how simple such a CPU upgrade would be)?
This question was solved.
View Solution.

This image is from the maintenence manual for the HP 8000 Elite
Upgrading to a Core 2 Quad Processor or a Core 2 Duo would be a great improvement in power.

Dv6-1216sa cpu upgrades?

running win 7 32bit, (although will be upgradeing to 64bit soon)
bios up to date F:18
current cpu: AMD Turion X2 RM-74 2.2GHz
currently my ram is 4gb, which i can only use 3 of hence the upgrade to the 64 bit os soon
i will be upgradeing to 8gb ram,
just wondering what are my cpu upgrade options? would rather get the most out of this laptop, cant afford to buy a new one, willing to put about €100 into this

Hi:
I am not an expert on AMD processors.
If you think the ZM isn't a whole lot better (you need to look at the specs more than just the speed), then I wouldn't do it.
The speed isn't a whole lot different and the L2 cache is the same.
Normally the faster processors will run hotter when all else is equal (voltage, etc).
Upgrading the memory is the cheapest, easiest route to a better performing PC.
And definitely keep the vents and fan clean of lint and dust as much as possible.

CPU upgrades for a G4

I just bought a PowerMac G4 from eBay. I'm new to Macs and so far I haven't found much info on this model. It is an M5183, 733MHz, 512MB. I would like to upgrade the CPU. What are my options? What should I look for on eBay?

Also review the user report database on this site:
http://forums.xlr8yourmac.com/cpureview.lasso
You select your Mac model and the brand of CPU upgrade you are considering and get a number of user reports on how the install went and how it works.
NOTE: When you select your Mac model, you probably should choose "Apple G4 AGP Slot" unless you know you have a dual processor model.
You might want to ask in the Apple forum for for older G4 desktops (yours is older than the late FW800s and MDDs covered in this area) to see if someone else has already performed such an upgrade on a machine like yours:
http://discussions.apple.com/category.jspa?categoryID=113
I'm a little confused about which model you really have at this point. The M5183 number returns a Powermac G4 (AGP graphics) that had a 400, 450, or 500 nHz processor. I wonder if yours was already upgraded once (doesn't affect future upgrades).
Look for extra stickers on the back and see if any have "M" numbers that end with capital L's, a slash (/) followed by another letter (example: M7825LL/A, M7825LL/B). Those may help narrow the search.
A good resource for Apple Specs and how they were configured is the MacTracker database. Its format is more consistent than Apples' specs sheet format, making it easier to cmpare models. It's free and it's here:
http://www.mactracker.ca/
You can also run System Profiler (do "About this Mac" and click "More Info.." in the resulting window. On the first screen is "Hardware Overview." Copy/paste that (without the serial number) into a post here and that should precisely nail down your model.

CPU upgrades - UK

Has anyone in the UK tried this CPU upgrade from Daystar?
http://daystar-store.com/index.asp?PageAction=VIEWPROD&ProdID=555
I am unsure about, due to the shipping, and I was worried it would cost me much more. At the current exchange rate, the 1.83ghz upgrade - which is the one I would like to get, comes in at £236.96.
Could someone tell me what the basic shipping cost to the UK would be?
Thanks

I may be cynical, but I read the promo on this chip and you're only getting a very slight gain in clock speed. Trouble is you still have the same system bus performance. I've upgraded chips before and got a slight life extension. But with the Macbook Pro on offer, surely the money is better invested in a replacement laptop?

Hi
IMHO dual processor upgrades have advantages and disadvantages.
On the one hand OS X does make good use of dual processors and most apps these days seem to be multithreaded to some degree. I guess this will only improve in the future as more machines are released with dual processors and/or dual cores and more software is produced to take advantage of them. I guess the main exception is games, some of which only make use of one processor, but then if you're running more than one app at a time, you'll still be using both processors to some degree.
On the other hand, dual processor upgrades are more expensive, both processors share the same relatively slow 133MHz system bus and in general are 'only' 40% faster than a single processor running at the same speed, they generate more heat and most 7447 based upgrades are overclocked, so two overclocked processors are perhaps going to be more problematical.
I agree with PB PM in that a single 1.4GHz 7455 based upgrade (with level 3 cache) would give you the most bang for the buck. IMHO the 466MHz Digital Audio G4 is the computer likely to gain the most from a processor upgrade, as it was the slowest G4 produced to still have a 133MHz bus and x4 AGP slot etc.

Photoshop CS6 Running Slow After GPU/RAM/CPU Upgrade?

Hi all,
I recently upgraded my Mac Pro 1,1 with the following:
CPU Upgrade to 2 x 2.66GHz Quad Core
RAM Upgrade to 14GB
GFX Upgrade to ATI Radeon HD 5770 1024mb VRAM
Everything seems fine. My temperatures are normal and things are seemingly speedy.
My problem is that Photoshop CS6 seems to run a little slow. I'm only working on web files (72dpi) that are yes, sometimes quite long in length (5000px high), but that has never been an issue.
Some problems I've noticed:
When I click to edit text, it may take 2 seconds before I can start editing it
When I scroll upwards it chugs a little
If I grab an object/shape and drag it around too quick, it might lag a little
I'm not sure how to explain it really, but for the couple hundred dollars I spent on upgrading my maching, I wouldn't expect any of these things to be an issue.
Here are my photoshop performance settings:
Any suggestions would help. No trolls please.

Something to try: Reset Photoshop's preferences to defaults.
Press and hold Command - Shift - Option immediately upon cold-starting Photoshop. If you get the keys down quickly enough - and you have to be very quick - you'll get a prompt asking you to confirm deleting your current preferences. Once you confirm that, Photoshop will start up with a default set of parameters, though you will still find you can select your named workspaces and (I believe) your Actions will all still be there.
Try immediately to see if the problem recurs. Then methodically make your preferred preferences changes, quit Photoshop, and restart, then test to see that the problem hasn't recurred.
With some luck, you'll have cleared up the sluggishness, and will have been able to make all your preferences changes you like without it recurring.
This really can work.

CPU upgrade of my Satellite Pro L300-152

hello
my laptop is a :
Toshiba Satellite Pro L300-152
Model no. PSLB1E-01R015EN
Celeron 560 2.13GHz
Can someone tell me which CPU I can safely upgrade this with, I use it in a fairly cool environment and would like just a few more 100mhz from it.
Thank you for your support

Before we start discussion about CPU upgrade check please this Toshiba document - http://aps2.toshiba-tro.de/kb0/TSB9401AX0001R01.htm
My personal opinion is that CPU upgrade will not help much and you will not realize some big difference in notebook performance. In my opinion you need more RAM or better and faster SSD. This brings better and more performance than some CPU with 100mhz more than old one.
