This processor is pretty old as of the time of this review (2/5/20), but according to the motherboard spec for the HP Pavilion a1767c Media Center, is the highest performance processor available. It was used to replace the Intel Core2 Duo E4300 that was originally installed. This upgrade increases clock speed from 1.8GHz to 2.66GHz, L2 cache from 2MB to 4MB, and bus speed from 800MHz to 1066MHz. I didn't do any formal testing, but the "seat of the pants" feel is an overall improvement in performance, for me, most noticeable in video streaming.

In typical eBay fashion, they ask for an immediate review of a product only just puchased, and then strip away most of the usefulness by not allowing me to discuss the seller, or include the very links that consumers need far more than opinion: Select a processor based upon it's ability to perform the tasks you require w/in the environment you're in ... cold, hard fact. My Pentium D operates at a much higher frequency, and is also dual core, and is 64 bit as well, yet the Core 2 Duo outperforms dramatically in every way, most esp. when multi-tasking, and uses considerably less power (which is the enemy of performance ~;-) Costs 2~3 times the money, but at a time when my old processor can be found on here for ten bucks ... the savings on my electric bill will pay me back the difference in no time: Cost should only be considered if the improvement were to be slighter. But, it's a HUGE boost. Visit your brand's website, unless it's Acer (or Gateway, which they now own). Replace your machine if it is, but update your bios ... the actual manufacturer of the system board is often the best source. Visit Intel to determine exactly which processor(s) you have to choose from in your very specific situation -- it ain't just the socket that's gotta match up, and they are really good at listing exactly which does (and better at explaining why this is critical). Check out the many benchmarking/comparison websites, so as to determine which of these choices is best for your needs ... for sure, you will find the C2D outshines the D. Consider a working pull, from a well-proven seller. If they just upgraded, then their CPU is in just as good of shape as your own is -- they, too, just wanted more speed, but in a somewhat better machine.Read full review
This was the best CPU for the HP Compaq DC5700 Microtower. Upgraded from a E6400 2.13 GHz, 2 MB L2 cache. The additional 500 - 600 GHz clock speeds make a huge difference and with the 4 MB L2 cache, Windows 10 runs stable with 8 GB and a dedicated PCI (NOT EXPRESS) GPU. Video streaming over Plex, Utube or Netflix runs smooth.

This E6700 cpu is very fast compared to Pentium D 925, easy to mild overclock on air easy 3.0 clock!! very good buy IMHO!

Upgrading CPU to this one had allowed me to use 64-bit virtualization on my relatively old HP Pavilion a6220.cs. Corresponding the Wintel politics the MS Windows 8.1 Hyper-V virtualization, of course, does not support this (7-years old very outdated:) CPU to serve virtual machine. Everyone knows it, just MS-wintel not (no averse to, disappointment only), therefore i successfully use 3-rd party software VMWARE and/or Virtualbox. I also changed the SATA hdd mode to AHCI - needed for virtualbox (search in browser for 'How can i make IDE to AHCI in windows 8'). Enlarging system RAM greatly assist the operation of virtualization - I recommend upgrade to 3-4 GB RAM (China is cheap) Do not forget set the number of cores to 2 for performance of VMWARE, in Virtualbox you do not care about it (in both cases u have to select 1 CPU (if u do not have more)). Virtualizing is then at good performance on the both - linux and Windows. Virtualizing helps reducing of system reboots for using features of the other OS on multi OS computer, reduces need to have other system (or another instance of used OS) independently fill installed, allowing direct access to another OS instance using selected virtual machine manager. Case cooling! - You have to care about case cooling, in extreme traffic of CPU it produce a little more heat than original slower CPU. GPU, chipset and added hardisks are good warmers too. Summary produced heat can downgrade your's OS stability and harm computer hardware. In my PC its indestructible (unsinkable:) power supply with its fan does not care about heat well-being of the other parts of computer, only one original system cooler is insufficient, and air circulation in case is originally absolutely not solved - the most apparent, this resulted in overheating graphics card processor (GPU), receiving heat also directly from an underlying passiveonly cooled chipset. So I added some fans and made some changes: - changing outlet orientation of orig. system cooler (placed below) to inlet; - addition 12 cm inlet fan opposite the CPU (active cooled) and chipset (passive cooled) using of existing perforated area on case); - changing location of SATA hdd from down position to front upper position below DVD mechanic and I added 7 cm fan in front of hdd and blank position below him (I had previously removed unused hp removable drive from there); - and finally I added (after removing of shutters on PCI slots area) 8 cm powerful outlet fan bellow power supply unit from the outside - the finale continues with removal of by me added old IDE harddisk (superfluous; producing big heat; wide IDE cable hampers air circulation) - and the miracle is on the world - PC is cold! (disconnected removed hdd can be then occasionally temporary attached e.g. as repository for system partition full backup) - I am considering adding automatic fan speed controller with temperature sensor to save some electricity in the near future, or connect some fans into the socket for the system fan on the system mainboard (will be subjected to the tests). -------------- Summary: upgrade CPU, RAM, solve system cooling, resolve hdd mode, use 3-rd party virtualization software. -------------- Author has several (many:) years of practice in system administration and software development, technical university graduatedRead full review
