Upgrading CPU in a older computer

[AdamGrant82]

Hi new here I have a HP Compaq dc5800 Business PC SFF  I have already done some upgrading I am wondering if anyone knows if I can install the Intel Core 2 Quad Q9550 2.83GHz in this computer there's not much on HP's site for supported Core 2 Quad's for this model I have the Core 2 Quad Q9300 installed now used to have a slow Core 2 Duo. By looking at HP's site this is the fastest CPU it supports but when I look around there is a hint it may support as high as Intel Core 2 Quad Q9650 what I do know is the Q9550 and the Q9300 came out on the same day in January 2008 and the BIOS in my computer is March 2008 I found a site showing more listed CPU's and the  Q9550 wasn't even listed. I could use some help since I posted on Intel's and HP's  forum sites and the only response I got was a guy from Intel's sites telling me to buy new like this computer sucks also this guy said installing a unsupported CPU will kill the motherboard and CPU is it worth the risk? I never heard of a unsupported CPU frying a motherboard it just won't post but I could be wrong. I'm months away from buying a new laptop and my AMD based (HP Probook 6465B with a A8 quad core) laptop I got now is 7 years old and not working the best so I want to use this desktop for my main computer if and when my laptop dies.

System spec's

That have nothing to do with the cpu compatibility. Mostly is the manufacturer of prebuild who may limit which cpu you can install in the system. 

[AdamGrant82]

So how do I know if it will work without trying to install it? I have already ordered that CPU for $30 on Ebay

You could probably scan internet for someone who already done it (I’m more than sure that someone was trying it before) but because you ordered it already just wait till you get it and than test it yourself. If its work than great , if not just return it

[AdamGrant82]

Will it fry my motherboard if it's not supported? Also I was thinking of buying another socket 775 motherboard that will support that CPU if it don't work in this computer so I'm not worried about it not working but I am worried it could damage my motherboard since this computer is working great now also what would be the difference between the Core 2 Quad Q9300 and the Core 2 Quad Q9550 The Q9550 is clocked higher (2.83GHz) it has 12 MB L2 Cache vs the Q9300's 6MB  L2 Cache(2.5GHz) will I see much of a difference between the two CPU's to make it worth the risk trying that CPU? I don't game but I do convert 1080 HD videos from time to time maybe that's what killed my AMD Laptop I find it funny that this desktop being 4 years older then the laptop is way faster and so much smoother running even back when the laptop was working right it still wasn't near as fast as this computer.

It’ll not damage your mobo, if its not supported it’ll simply not gonna boot , so don’t worry about that. 
As of buying another mobo , well this platform is outdated and I wouldn’t invest any more money into that, better if you save some money and go Ryzen

It'll probably work if the 9300 works. 

The manual only goes up to E8400 or Q6600 though lol.

The laptop I'm looking at buying has the AMD Ryzen 7 3750h I already bought some upgrades for it

G.SKILL Ripjaws Series 32GB (2 x 16GB) 
SAMSUNG 970 EVO PLUS M.2 2280 1TB
Windows 10 Pro

Should make for a great laptop I only want this desktop as a spare computer just in case my laptop dies it don't get used much. For what I paid for everything it's still a great computer even if it's older. Maybe if this CPU don't work I may just put all my money into buying the new laptop first then maybe build another cheap desktop around the CPU. If I do that I will try to get the DDR3 boards with newer and faster ram

As you can see there's not much showing for being supported don't you love HP? they never update their CPU lists even after new ones come out it's funny

Well it's an office pc. So almost always..... nobody swaps the processors like you are doing

 

I think it'll post though. It's still a Core 2 Quad.... as long as it's within TDP spec for the board's bios, should be just fine.

It's the same as the one I got now installed both are 95 watts both are Yorkfield cores and both came out in January 2008 the only difference is the clock speeds and the L2 Cache but how much would the difference be with the Q9300 being 2.5GHz with 6 MB L2 Cache vs the Q9550 being 2.83GHz and 12 MB L2 Cache that's the only difference between the two CPU's

Yep

Luckily with the age of the motherboard and bios, it's likely that as long as it's 95w TDP and Core 2 quad.... it just will work period. 

There are some cases where unsupported processors work on overclocking motherboards (non oem) while the cpu is not listed.

Good to know.

Maybe someone would have a idea what's going on with my laptop it's a HP ProBook 6465B Windows 10 Pro
AMD A8 3510mx 8GB 1600MHz Ram about 2 months ago it stared to slow down enough every few weeks Windows needed to be reinstalled now it's almost every 2 weeks When I have more then one tab open and I switch between tabs the tab turns white for a few seconds. Two weeks also I was watching a video of Linus Tech Tips on Youtube and the screen(my TV) went blank with "No Single" messages on the screen this lasted about 10 seconds when it came back there was nothing on the taskbar not even the clock for a few seconds then it came back like Explorer reset it self. Some websites when scrolling down is choppy and jumping all over the place. Now this just started happening at random I put my laptop in hibernating when I turn it off at night last week when I turned it off about a few seconds it turned itself back on even after I turned it back off in hibernation 3 time I had to turn it off without hibernation only did that once that day then last night when turning off the laptop same way through hibernation it turned off and a few seconds later it turned itself back on for about 10 seconds then went back off I never ever seen this before and I been building and working on computers since Windows XP I tried different boot drives no change tested the ram and it passed with Memtest and it's a clean install of Windows 10 with only what I need installed. All bloatware removed. Any ideas anyone? Someone on the HP site said he thinks it's a bad capacitor on the motherboard and he said there's no way to test for this and the laptop's day's are numbered (that's why I got this desktop)

Well Laptops tend to just run hot in nature. When that happens, the cpu throttles. Sometimes throttles pretty badly. Since it's an IGP, you'll experience graphics issues too. 

Do you monitor the temps? 

How's the batteries health (not charge)?

Does the issue occur more or less often when plugged into the wall.

And yea, a bad cap or VRM cpu side could cause some issues, but you'd see strange things like voltage randomly fluctuate or become very high or very low. (outside the norm)

The temps seem good the CPU never goes over 65C when maxed out and idles around 38C to 40C The battery is not installed I use this laptop like a desktop also to point out I have a 16GB ram kit by GB Micro and this laptop does NOT like it at all while it does boot it acts ten times worse and it shows HP are supported heck even Dell is supported by this ram This laptop has just over 20,000 hours on it what about a power adapter problem? one person suggested it could be a failing CPU but when I stress it out it's okay. But I did notice another problem when I'm downloading large files or when the CPU is maxed out or close to being maxed out the wireless mouse becomes useless very choppy no clue if that's related

[Guest]

It doesn't take much cpu to move a mouse cursor. Is the memory completely filled up? 

Programs getting pushed to page file maybe? 

 

Strange issues for sure. Could be memory related. 

Cpu isn't really the most powerful either. pretty low end, low clocks. Basically a P960 in performance at 1.8ghz.... that's pretty slow for todays standards imo.

 

I'm on the fence if it actually has an issue, or it's just way under powered for your uses.

The ram when the laptop is at idle uses around 1.4-1.7GB when I'm running into these problems the most I seen it up to was 50 to 60% used range It's Samsung 1600 MHz ram I just bought awhile ago on Ebay it used to have the 16GB kit in and I took it out when I bought the Samsung kit the only other ram I have that would work in this laptop is a 4GB kit running at 1333MHz not enough ram. My guess the reason this desktop is faster is it's a better CPU being the Intel Core 2 Quad Q9300 but the ram is only DDR2 800MHz you would think that would make it run slower then the much newer laptop. I am wondering could all the problems be caused by using a 40 inch TV for the monitor on this laptop?

Tough to say. You'd perhaps try a different display, smaller maybe. Could try different resolutions on the current TV. 

I'm assuming all the drivers are up to date and such.

This is an interesting statement. (I'm re-reading) That sounds like the driver crashed. (maybe NOT hardware related?)

 

Are you using the AMD drivers or the W10 installed drivers? (W10 should update this automatically though)

 

You can reset the video driver perhaps when you start encountering issues. 

Just hit these 4 keys at the same time to restart the driver subsystem.

There's no Windows 10 drivers on the AMD site for this older APU it only goes up to Windows 8.1 then the support ends but Windows installed the drivers since using the Windows 8.1 drivers caused problems when I tried to install them from the AMD site also there's no drivers for Windows 10 for this laptop nothing past Windows 8.1 even on the HP site there's nothing. This laptop don't even have HDMI only display port that only puts out video no sound.This was a free laptop my friend gave me a while ago to get my by till I can buy a new one.Maybe I'm pushing it too much?

Does it overclock?

It's a OEM laptop so no everything's stock, now I got another problem with the laptop I have the laptop power setting set to not turn off the laptop and only turn off the monitor after 2 hours there's times I had to leave the laptop run over night it always stayed on well twice so far tonight after being idle for a short time the laptop going into hibernation and turns off the first time I thought I may have put the laptop into hibernation and just forgot but I know this time I didn't and it just went into hibernation when it's not set to in power options it's a clean install of Windows as of 3 days ago. So weird cause the TV was off but left the laptop running.

My only suggestion from here is to try Window 7 instead of 10. 

 

If you don't have W7, you can pick up a copy on USB for dirt cheap.

This laptop came with Windows 7 Pro but I used that key code when I installed Windows 10 Pro also Windows 7 won't be supported for much longer and I don't have the install DVD anyway I tossed all Windows install DVD's older then 8 out years ago. I guess I will keep using the laptop till it dies or becomes mostly useless then switch to the desktop I just got done rebuilding I hope it will last till I get my new laptop but the way it's going down hill I don't think it's gonna last much longer but maybe it will last longer then I think and will hold on for another 4 or 5 months. It's a pain but it's still usable if I don't mind re imaging the boot drive every 2 weeks or so

Well I think W10 is just a little to heavy for that laptop. W7 will be much slimer, and use far less resources. The nice thing is, that's a link to ebay.ca - 15$ ca, not us currency. That's cheap. Think I seen one for 10 bucks ca.

I really like Windows 10 way too much to downgrade now I rather switch to the desktop before I do that since the older desktop is running Windows 10 very good it's a lot better then the copy of Vista that would have came with it when it was new, never liked Vista that was the first thing I took off this desktop was the Vista coa sticker. But all said and done this desktop only cost about $200 to $250 for everything that's all the upgrades and replacement parts and buying the stock computer($5) not bad since this computer seems to be selling on Newegg with less spec's then what's in mine for around $500 or so. That laptop on the other hand isn't going for much used even if there's nothing wrong with it and it's just not powerful enough to meet my needs it's just not worth selling I'd be lucky to get $60 for it the Seagate 1TB SSHD cost more then that when new. I'd rather just keep the laptop for a spare. Also before I ordered any parts for this desktop I inspected everything and the motherboard looks like new(after I cleaned it up and was able to see the hardware yes it was that dirty I had to take everything out of the case and clean each part then rebuild it) I didn't see any thing that looked like it could be going bad. I did order another power supply for the computer just in case I rather have spare parts so I can keep this computer going for as long as I can.
