UPGRADE FROM E550 2.5Ghz processor TO Intel Core 2 Quad Q6600r

flyalaska · Dec 5, 2015

My HP Pavilion a6642p Desktop PC, Model #: FK572AA, Serial #: MXU8410CZT came with a E5200 processor. Would upgrading the cpu make a significant improvement? What processor would be best for me?

Rocket_Jas · Dec 5, 2015

Yes, an upgraded processor would make a massive improvement as integrated graphics is all you have, an upgraded processor would be a great improvement to smoothness of your PC.

I would recommend having a look at this page : https://uk.pcpartpicker.com/parts/cpu/#k=13&xcx=0&sort=a7&page=1
a list of all processors with the LGA 775 socket, you can choose one to suit your price point

Hope this helped, Josh

Here is the official list of all processors supported by your motherboard listed in order of descending release date: http://ark.intel.com/search/advanced?s=t&SocketsSupported=LGA775

You should check your motherboard for compatibility with the chip as some OEM boards are very picky on how many cores it accept.

The LGA775 dual core chip with the best performance to price ratio right now in my opinion is the E7600, which sells for about $10 used on eBay.

There is a very good possibility it won't work. The E5200 is a 45nm chip, and the Q6600 is an older 65nm chip. Get the manual for your computer online and find the supported processor page. The Q6600 requires a lot more power than the E5200 and the motherboard might not be able to provide it. Be sure you have the latest BIOS update as support for newer processors is added that way. Most likely Quad is Q9550/9650 or Q9505. there are also very low power Q9505s, and Q9550s chips that draw about the same watts as a dual core. See if they're supported.

Than you William, I was wondering about the power. <y 250W power supply isn't much but I don't know that the baord allows the processor. it does support processor upgrades:
• Intel Core 2 Quad (Y) Q9xxxx
• Intel Core 2 Duo (W) E8xxx
• Intel Core 2 Quad (K) up to Q6600
• Core 2 Duo E6x00 (C) up to E6700
• Core 2 Duo E4x00 (C) up to E4400
Unfortunately I don't know enough about them to know which is my best option for the money yet.

E8600 is 3.33Ghz 6M cache. Nice Dual core. Q9505 has less cache than Q9550 and is 6% slower because of that. Q9650 is fastest Quad. The 9XXX"s" versions draw 65W. There are 2 different E6700. One is 45nm 3.2Ghz, and one is 65nm 2.66Ghz. Q6600 is 65nm but E8xxx is 45nm so it could support either one, or even both. There is a very rare E8700 3.5Ghz. By very rare I mean some people believe they don't exist. But if you can find one more power to you. Don't bother with 65nm chips in a low power application like yours.

Upgrade to a Q6600. The biggest unlock is the ability to play games that block dual cores. Not to mention gaming performance would be about doubled from the Pentium due to utilization of 4 cores.

And don't go for anything Core 2 Quad newer than Q6600, because they start costing much more than $20.

william p · Dec 16, 2015

Q6600 is cheap because it's slow, and power hungry. If you decide that's best for you try for a Q6600 SLACR, This is the G0 stepping and draws less power so it runs a little cooler. It was a favorite of overclockers a few years back. Personally I'd go for a faster $40 chip and maybe be able to put off replacing the computer a little longer. But I don't know your situation. If your applications don't use 4 cores there would be no improvement, and a fast dual core would work better for you. Best of course would be a fast Quad which can handle anything.

okcnaline · Dec 16, 2015

Well, the Q9550, the last time I checked, starts at $40 or so for non-functional CPUs (some were missing caps).

Power is not a problem. My old HP 6200 Elite packs a Q9300 with a 240W PSU.

A Q9300 goes for $20-30 regularly:

http://www.ebay.com/itm/Intel-Core-2-Quad-Q9300-PROCESSOR-SLAWE-2-50GHz-6M-CACHE-1333-MHz-/201477187695?hash=item2ee8f9e86f:g:VlQAAOSwKIpWDDBo

http://www.ebay.com/itm/Intel-Core-2-Quad-Q9300-2-5GHz-6MB-Socket-775-SLAWE-Processor-/391331081417?hash=item5b1d266cc9:g%3Cimg%20data-src=

Far better than a Q6600.

True, the Q9550 is pricey, but you can find Xeon E5440s with the pin adapter for quite cheap:

http://www.ebay.com/itm/Intel-Xeon-E5440-Quad-Core-2-83GHz-12M-1333MHz-Core-2-Quad-Q9550-771-775-mod-/111851202270?hash=item1a0ad9e6de:g:1w8AAOSwo0JWIc5O

That does require modding the motherboard and BIOS, though the seller does say he'll help with the BIOS.

You can even get a working Q9550 for $40:

As an owner of a Q6700, QX6700, QX6800, QX6800SLACP . I've learned it's cheaper to do it right the first time. The very highest CPUs of any series are usually overpriced. One tier down is usually the best value, often 1/2 as much. From the nature of the question being asked I didn't think the OP was ready for a Xeon swap that could require BIOS microcode mod. Delidded.com has info on Xeon swapping. Q9550 is probably best value. Q9650 best performance.

here is a whole page of them. http://stuccu.com/s/Quad+Core+Q9550-MbSLsTI-Buy-Exclusive-Deals-70-OFF-Save-Big-Lowest-Price-On-Quad-Core-Q9550-Best-In-Stock-Fast-Free-Shipping?mt=b&keyword=quad%20core%20q9550&ap=1t1&cid=88237787699&caid=5617b820b1b1c725f4a6ad71&netid=1&network=g&aaid=5617b820b1b1c725f4a6ad73&gclid=Cj0KEQiAtMSzBRDs7fvDosLZmpoBEiQADzG1vJZ5ytC53uFDJQ-Sf0JgHbaW1A_FUm5JzPls1y7GXC8aApvy8P8HAQ

Chayan4400 :

x) Alright! I didn' know there was a Q9300, so I guess this would be the best value.

Chayan4400 · Dec 16, 2015

okcnaline :

Agreed. The Q9300 is actually a very capable CPU - it performs almost identically to my i3 4130, and for a ~7 year old CPU that is really saying something!

william p · Dec 16, 2015

The Q9300 is the same speed in single and 2 thread applications as the chip you have now. It will only perform better in 4 thread games. The Q9550 will be faster in everything, including faster than the Q9300 in games. It's up to you whether that's worth another $10-$20.

19% better in single thread, and 15% better in 4 thread.

BTW 28% faster than Q6600.
