Intel Q9650 LGA 775

100% Positive Reviews


Pros: Quad Core, Low VID, High Performance, and Bargain!

Cons: No Hyper Threading, No Turbo Boost, No Built in Graphics Core.

This chip is pure awesome 775 Quad core with low VID (mine 1.175V)


With Great overclocking potential!


Performance after overclocking is close to high end 1st gen SB i7s!


With this minor upgrade from E5200, I can definitely say my next major upgrade will be done in 2015!


We have a **Q9650 Club** on OCN. Check it out! specool.gif


Recently, I've pruchased ASUS U3S6 to make my current sig rig to last longer!


Update: I've added the ASUS U3S6 in the product database and have written a review on this expansion card.


Pros: Performs well, have two browsers with many tabs open, an AV scanning, Secunia PSI updating, Windows Updates running, and still doesn't choke!

Cons: That the CPU's run was short. Intel could had gotten 3 more years out of this chip, maybe developed a 4.0GHz on LGA 775!

I have this fantastic CPU in a Dell Optiplex 780 DT edition, and to this date, it's still the 2nd best PC that I have, out of an arsenal of seven.smile.gif

If I don't run it for a month (rare), I can boot into the desktop fast, running a 128GB Samsung 840 PRO, open a browser as soon as the PC is booted, the AV/AM apps are updating & scans are beginning, Secunia PSI is updating what software it can, Windows Update is downloading updates, can open folders at will, all within a minute of booting, In the year that I've owned this PC, have yet to see it choke or freeze, as many dual cores, and even many of CPU's that were later built.thumb.gif

As for the absence of graphics, that's what onboard MB & discrete GPU's are for, a CPU is supposed to be that only, and the Q9650 is a da** good one! That's why to this date (05/21/2016), eBay suppliers are still getting $70-100 for those that were one owner models (or came from certified business machines). Even the ones that's passed hands a few times & may have been OC'd will still fetch $60-75 easily.

I lucked in in this jewel, not only did I get the PC, also Windows 7 Pro x64 plus the Q9650 for $114 shipped ($94+$20 shipping)! biggrin.gif

If there was a con, not the fault of the CPU, rather Dell's lousy support (plus two pages of misinformation by Intel that the Q45/43 chipsets had support for 8GB max RAM), had to RMA two sets of RAM, finally found the right set at Amazon, the MB required 'double sided' RAM modules, and grabbed two 8GB kits while the getting was good, because the market is saturated with these PC's. Though few has the Q9650, the Q9550 was more plentiful, and probably equally as good, was going to get one of those, and seen this one with 17 sold in the last 24 hours & only 3 left, so took the chance & never looked back.

The Intel Core 2 Quad Q9650 will run a max of 16GB DDR3 1600 (double sided) RAM, but will downclock to 1333MHz, don't let any OEM 'documents' fool you into otherwise. The folks at Intel never bothered to correct typos in their 'whitesheets' for Q45/43 chipsets (8GB max for DDR3, and 16GB max for DDR2) or didn't bother to revise to update with the times, am unsure which is the case. Plus Dell has the PC listed as running a max of 8GB DDR2 RAM, what dumb people, at least CNet got the specs half way right.biggrin.gif

I'm just glad to have this fantastic CPU, on Windows 7 Ultimate, has a score of 7.3, as does the RAM, SSD has 7.8 (on a SATA-2 MB & RAPID is not enabled), and only the GPU (the one bundled with my XPS 8700, had to use a low profile bracket) a Dell OEM Radeon 7570, 1GB GDDR5 is the lowest rated component, still reaching 6.9 for both GPU scores. A WEI of 6.9 is not bad at all for an 8 year old PC, and if it weren't for the BTX MB, could install in a mid tower case & with a decent PSU, add a GPU to get 7.9 graphics.smile.gif

Am still considering finding a new LGA 775 MB with 4 RAM slots, though I know that SATA-3 won't be possible w/out an add-on card, and use the CPU for a new build, there's nothing wrong with it, the PC was only used by one corporation, cleaned up nicely before arrival to me, and this Q9650 rocks! It's kind of hard not to include the other components, because it takes an entire computer for the build to perform, not just the CPU itself. smile.gif

My recommendation is that if one cannot afford a new computer that will likely be junk for under $500 anyway, look on eBay for one of these former corporate PC's with the Q9650, most of the large OEM's produced a business class PC that features the fantastic Q9650!thumb.gif

The CPU also makes a nice folding PC that will run 24/7 w/out issue.smile.gif

This is the only computer that I have that was built prior to 2010 that's still going strong, and can still hang with many of the models produced today. Beats most any 'budget' model PC hands down. Finally, to those who says it's a power hog, it's running on Dell's 280W PSU. along with the GPU, and seldom do I hear the fans kick in.

If one finds a PC with the Q9650 for $125 or less, and has a warranty of any kind, grab it! For the CPU alone, it outperforms much of what AMD builds today, while using less power to do so!biggrin.gif

On a scale of 1-10, I rate the Q9650 a perfect 10.smile.gif

EDIT: Without booting the PC, found the Speccy spec link for the PC on another site where I posted.smile.gif




Pros: With a decent overclock this is a very capable CPU

Cons: Need of aftermarket cooling for overclock

I was able to pick up one secondhand for $140 and with my Cooler Master Eisberg 240L I achieved a 24/7 overclock of 4.02 ghz and it is very capable.

Four dedicated, physical threads help operating systems and applications deliver additional performance, so end users can experience better multi-tasking and multi-threaded performance across many types of applications and work loads. Intel® Wide Dynamic Execution Improves execution speed and efficiency, delivering more instructions per clock cycle. Each of the four cores can complete up to four full instructions simultaneously. Intel® Smart Memory Access Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution. A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further improve this feature, with more efficient methods of loading and storing data in main memory. Intel® Advanced Smart Cache Provides shared level 2 cache across each pair of cores that can be dynamically allocated to each processor core, within the pair, based on workload. This efficient implementation increases the probability that each core within the pair can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance. Intel® Advanced Digital Media Boost Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of applications, including video, audio, and image processing, and multimedia, encryption, financial, engineering, and scientific applications. The 128-bit SSE instructions are now issued at a throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock basis over previous generation processors. 45nm versions include a new Super Shuffle Engine, which improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see additional performance improvements. Intel® Virtualization Technology (Intel® VT) Allows one hardware platform to function as multiple “virtual” platforms. Intel® VT improves manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. Intel® 64 Architecture Allows the processor to access larger amounts of memory. With appropriate 64-bit hardware and software, platforms based on an Intel processor supporting Intel® 64 architecture can allow the use of extended virtual and physical memory. Execute Disable Bit Provides extended virus defense when deployed with a supported operating system. Memory can be marked as executable or non-executable, allowing the processor to raise an error to the operating system if malicious code attempts to run in non-executable memory. This can prevent the code from infecting the system. Digital Thermal Sensor (DTS) Provides for more efficient processor and platform thermal control improving system acoustics. The DTS continuously measures the temperature at each processing core. The ability to continuously measure and detect variations in processor temperature enables system fans to spin only as fast as needed to cool the system. The combination of these technologies can result in significantly lower noise emissions from the PC. Intel Designed Thermal Solution for Boxed Processors Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance6. Fan speed control technology is based on actual CPU temperature and power usage.
