In today's usage environment, processor speed alone is not enough to ensure a great experience. The advanced dual core Intel Pentium D 945 processor features two 65nm processor cores each running at 3.4GHz with integrated 2MB L2 cache. The cutting edge 65nm manufacturing process significantly reduces power consumption and improves thermal performance. Users today have high expectations for their PCs and want the most productivity and enjoyment from their PCs when running multiple applications simultaneously. The Intel dual-core processor delivers consumer value by providing additional computing resources that expand the PC's capabilities and provide platform-level advancements for consumers in the form of higher throughput and simultaneous computing. Featuring Intel Extended Memory 64 Technology, Enhanced Intel SpeedStep Technology and Execute Disable Bit, the Intel Pentium D 945 processor delivers outstanding desktop and workstation computing experiences."
Dual-Core Processing with 2x2MB L2 CacheIntel dual-core Pentium D 945 processors have two complete processor cores in one physical package running at the same frequency. The cores share the same interface with chipset and memory, but each core has its own set of registers and cache for truly parallel computing. Each processor core has its own 2MB L2 Cache (4MB total) enabling improved overall system performance by allowing each core to have faster access to larger amounts of the most often used area.
Intel Extended Memory 64 Technology (Intel EM64T)Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the desktop processor platform to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
Enhanced Intel SpeedStep Technology (EIST)EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don't.
Execute Disable Bit (EDB)Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
Pros: Before I installed the D 945, I was already thinking about which upgraded heatsink and fan to get for it. Surprise! No upgrade is needed. I replaced the thermal gunk that came on the stock hs/f with Arctic Silver and enabled Enhanced Intel SpeedStep Technology in the BIOS and XP. With overclocking only .2 GHz to 3.6, the idle temp is about 22C (room temp)! Under a 100% sustained load, the temp tops out at about 50C. Air exhausted from the back of the case is actually cool. And my system has never been as fast or as quiet.
This is an ideal CPU for those who want a fast new dual core processor, but who want to keep their existing RAM and AGP video card.
Cons: None
Overall Review: Great price and great service (as usual) from Newegg! What more can you ask for?

It's a deal10/17/2006 3:33:19 PM
Pros: Wow this is faster than I expected, I might not need to upgrade like I planned when I got it.
Cons: A little warm and I got a few alarms but so is the Northbridge on my ASUS P5W Deluxe.
Overall Review: I planned on getting this for now and then get a core 2 duo when I have the money and when prices drop. Plays FEAR, Zero Hour, Doom 3, Half Life 2 all on HIGH Graphics. I'm using a Radeon X1650Pro Sapphire and 2GB Corsair DDR2 6400 on a P5W DH Deluxe.
Cons: i understand now , what alot of people were saying about this cpu running hot, with the stock cpu my average temp is 61c at idle,so i removed the heatsink and cleaned the surface and used arctic silver , and still idle at 60c,i dont get it i have been building pc's for years and never had a pentium run this hot, or the temp controls on my motherboard are not correct,i would say go for it, but dont use the stock heatsink and fan, i am gonna change mine out and see if that will make a difrence
Overall Review: i have been buying intel parts for years and ,intel needs to get it together and sell stock parts that at least operate in a more safe zone , if i went up another 10c i am at risk of burning up cpu and frying my mobo
Pros: Great buy for the money, high speed/low price, easy to install.
Cons: Runs maybe a bit on the warm side, but isn't nearly as bad as some would have you believe.
Overall Review: A friend and I bought identical computer setups, put them together, and voila. In his set up everything went fine, be sure to use artic silver 5 however. Setting up my system it was originally having serious heat issues (idle at 70c) and would sometimes overheat and shut down. After reapplying the gel NUMEROUS times start the thing up and it was idling at 43 c. The heatsink and fan that come with the chip work fine, as long as you get the right spread of thermal gel. If not - drop the extra 60 bucks on the zalman 9500. Otherwise, play around, do it right, and the whole set up works great.
Pros: Installed easily in my Asus P5P800 SE motherboard.
Runs in low 30's to low 40's (load)Celcius with stock HS/Fan. Has Speedstep.
Same as the Pentium D 950 w/o the VT which you won't use anyway. Also are all C1 stepping which is slightly better design.
I upgraded from a P4 3.0 Northwood. This is much more powerful in every respect.
Cons: Benchmarks are a bit short of the the newest Conroe entry level Core Duo CPU's, but still are excellent.
Overall Review: This was a great interim upgrade. The mobo was $xx and the CPU was $xxx. I was able to keep my Radeon 9800 AGP video card, and PC 3200 RAM, etc.
Cons: Not the latest processor.
Virtualization Technology Support disabled.
Overall Review: The price on this processor is rising every week. Better buy one now before the price hits $200.
As for heat issues, mine runs cool using a decent heatsink and AS 5.

Well Worth It2/17/2007 2:13:50 PM
Pros: Very snappy performance. I'm impressed!
Cons: Zero
Overall Review: Upgraded a Dell Dimension 9100 from a D-820 to the D-940. Wow! What a difference just from a seat of the pants observation. I used the stock Dell heat sink, along with a dab of Arctic Silver compound, and did not notice any heat related issues at all. The unit remains as quiet as it was before. XP Pro SP2 had no issues with the new processor and seems to load lightning quick now. I was not sure if this would be a worthy upgrade to an already good system. As it is now, I am very impressed. What a deal. Thanks Newegg. 3 business day delivery was super!
