I'm in trouble!

[LOLZpersonok]

So, a couple days ago, I purchased a processor upgrade for my HP Compaq DC7600 computer, to replace its 3.0GHz Pentium 4 630. The processor I purchased is a 3.4GHz dual core Pentium D 950. And I just realized I completely missed something.

 

I forgot to consider my computer's power supply when deciding on the new processor. I decided on the Pentium D 950 after viewing posts on other sites where users were looking for processor upgrades for the very same computer and they received suggestions from the Pentium D 925 to the Pentium D 950. So, I chose the best one there and I chose the Pentium D 950. Then I purchased one on eBay for $11.50 with free shipping.

 

I didn't realize the Pentium D 950 has such a high TDP, a TDP of 130 watts. Holy crap. My currently installed Pentium 4 630 has a TDP of 84 watts. Pretty big difference. And what's worse is that the HP Compaq DC7600 only has a 240 watt power supply and it is not user replaceable, as a result of its design. I may be able to remove it and stick in the 350 watt PSU from my old computer (which no longer works most likely due to a dead motherboard) but I would have issues with the fan in it and I would have to try and find a new spot for the hard disk.

 

Heat shouldn't be too much of an issue, because I can ramp up the fan speed quite significantly. It's maxing out and ruining the PSU I'm worried about. 

 

The computer is technically prepared for the processor, as I have updated the BIOS and microcode and with the updated BIOS and microcode, the motherboard completely supports the processor. It's just such a high TDP and my PSU is only 240 watts...

 

Any ideas?

What GPU  do you have?

If you're using integrated graphics you'll be fine with a Pentium D off a 240W. However there's little to no headroom for a dedicated GPU unless it's something reeally low end

 

The thing is if the motherboard's VRMs are capable of running the CPU reliably or not.

Yeah, now that I think of it, that's another thing I was worried about. I did want to install a dedicated GPU in it just for fun, but I guess it looks like I can't. Are you sure this 240 watt PSU will be fine with the 130 watt CPU?

 

I'm also not sure what motherboard VRMs are. I've heard the term, VRM, but I don't know what it is.

Depends what GPU. Something like an HD 5450, sure why not. If it's an OEM PSU then it will be fine running a Pentium D.

 

Motherboard VRMs are what take the 12V power given by the PSU and turn it into the ~1.3V power usable by the CPU. If the board supports the CPU it will likely work fine without any issue since it's an OEM board. It's just that a 130W CPU will put a lot more load on those VRMs then the 84W CPU, causing more heat in your case.

I'm not going to worry about an upgraded GPU anymore. They're probably being sold for ludicrous prices on eBay anyways.

 

Anyhow, I do believe the motherboard's VRMs can handle the CPU, but I'm not sure. How can I check?

Actually I just noticed what PC it's going into. I had the exact same PC and it came with a Pentium D pre-installed. Ran for years without issue. You'll be perfectly fine.

Are you sure the computer will be fine? This is an HP Compaq DC7600, small form factor machine. I'll be installing a Pentium D 950.

Yep. I had the exact same computer, also the SFF version. Mine came out of the factory with a Pentium D (I believe it was the 820). It was my main for 3 years before I built my current rig, and it ran without a single hitch, even with the HD 4350 I was running in it.

That CPU has a TDP of only 95 watts. The 950 has a TDP of 130 watts.

Are you sure the mobo supports the 950 specifically? 

[LOLZpersonok]

Are you sure the mobo supports the 950 specifically? 

According to HP documentation, the Pentium D 950 is supported by the DC7600 small form factor. HP Compaq DC7600 Business PC  Images don't seem to be shown, and processor support is listed close to the top.

 

I looked up the Pentium D 950 on CPU-World and it seems that the 950 may be configurable to a 95 watt TDP. If this is true then I'm going to be quite happy.

[LOLZpersonok]

Are you sure the mobo supports the 950 specifically? 

Okay, so I used an approximate PSU calculator from MSI and it came up with a recommended wattage of 215 watts. 

 

It asked for specific information and I inputted it accordingly, especially the processor. It calculated it with the processor being Intel Pentium D Presler 950 SL94P, which is the specific processor I bought.

If it's supported according to HP documentation then sure why not. I'd just try it, the worst that could happen is the mobo doesn't support the CPU, but if it works then it will work fine.

high TDP doesnt tell anything

As long as your cpu cooler is capable to cool 130W tdp heat, then you are fine.

Which a stock pentium 4 cooler basicly can do.

 

TDP doesnt tell a shit about how much power a cpu is using.

is a long shot but check if your machine have any overclocking capacities (yes, you have read right lol)  :lol:

 

and in this case, you can use this same tool to "underclock" your cpu, to match the power that your machine need  :rolleyes:

 

 

i did that on my 125w cpu to work on my 95w motherboard and all work perfect B)

 

but this was on an AMD machine, and i think intel don't let you do that so easy 

[A10-FTW]

more info i find  :rolleyes:

 

84w - Pentium 4 630

95w - (775_VR_CONFIG_05A) Pentium D 950

130w - (775_VR_CONFIG_05B) Pentium D 950

 

i tink you can move all this safe with your 250w PSU friend (no need to worry to much) 

 

- - - - 

 

(you can do some small underclock with the bios, if you need... well... if the intel bios let you) 

[Linux User]

I have the D 950 in an old dell and it has a 240 watt PSU. It runs fine, but remember I'm going off chip set graphics so there's no GPU to worry about

I think it'll be fine cooling the processor. The Pentium 4 Prescott series (which is what is installed right now) was a hot running processor, but still, it's a lower TDP. But anyhow, these business grade machines have to have good cooling. They're designed to be running all day long. For the CPU, you've got one fan directing air into the heatsink with a duct over it to guide the air better and another fan on the heatsink to blow the air away. Plus you can ramp the fans up to very high speeds.

Yeah I was planning on putting a dedicated GPU in my DC7600, but now that I know of the Pentium D's high TDP I think I will just leave it with the chipset graphics.

a small confusion that i need clarify friend 

 

is that TDP (thermal design power) is not the right number that we need use to do this maths

 

i do get your point (so i have avoid clarify this), but here the correct name is "watts" (or just w)

 

 

our old cpu have xxx watts, the new cpu have xxx watts, and motherboard support xxx watts max

 

(this is why normal people get confused when you use the word TDP here) 

 

84w - Pentium 4 630

95w - (775_VR_CONFIG_05A) Pentium D 950

130w - (775_VR_CONFIG_05B) Pentium D 950

 

- - - - 

 

leaving all that aside, is an old old machine friend :blush: (truly bottlenecking any gpu you put in there)

 

is time to move, to a cool (and cheap) new build, with a nice iGPU

 

 

i recommend the A8 5600k and the A8 6600k from AMD for a basic new build

 

(or a FX 6300 with a R9 270)  B)

 

 

sorry for not jump in some intel builds  :rolleyes:

 

i just don't recommend dual cores anymore to anyone, and all low intel have is dual core 

[LOLZpersonok]

Thanks for clearing that up about TDP.

 

I will be building a computer in the future, something far more powerful so I can use for video editing, rendering and playing games. I just wanted to upgrade this HP Compaq DC7600 for the fun of it. Nothing serious. The processor would; however, go well with something on the level of a Radeon HD 4670, which is the GPU in my old computer. I used that GPU with my old computer's 2.1GHz AMD Athlon X2 4000+ dual core for a long time and I never had trouble with it.

oh yea, i did had it (the HD 4670) and i love it   she work in any machine (she is perfect)

 

(not sure on the PSU but we can try it anyway)

I'm not going to bother with installing a dedicated GPU in this computer because the PSU won't have a lot of headroom with the Pentium D 950 installed.
