This is what is called a Qualification Sample (QS). That\'s a particular type of Engineering Sample (ES). Normal ES CPUs are part of the design development process and often differ from the final retail product, sometimes significantly. They likely will run at lower speeds, and may lack key features. A QS CPU is from much latter in the process, once the design specs are finalized. They are sent out to give manufacturers like HP, Dell, etc., a sample to work with in designing the boards, peripherals, and computers that the CPU will be used with. They are identical to the final product specs and work exactly like a retail CPU of the same model, in fact they share the same CPUID with the retail versions. My CPU is identified externally as a QGP5 ES 2.20GHZ. That\'s how you can externally tell the early Engineering Sample E5-2658 v3 from the later Qualifications Sample E5-2658 v3. The early ES versions will be externally identified as QEYx (QEYP, QEYF) rather than QGP5. And the printed clock speeds may also differ, as most if not all of them are slower, running at 2.00GHZ base speed rather than the final retail base speed of 2.20GHZ. Also an early ES CPU will not be identified by part number in CPU-Z. Instead the Specification box will read \"Genuine Intel CPU @2.00GHz (ES)\". Again, the speed listed may vary depending on exactly which early ES you have, but there will never be an actual part number in this box. A QS CPU will be identified in CPU-Z by it\'s specific part number, and the Specification box will read \"Intel Xeon CPU E5-2658 v3 @ 2.20GHz (ES)\". Both the production stepping release (M1) and the QS stepping release (R2) have the same CPUID 0306F2h, whereas the early Engineering Samples do not share this CPUID. The QEYP and QEYF share the CPUID 0306F1h. They also lack any stepping release spec. As far as I can determine, only QEYP and QEYF were used for the early E5-2658 v3 Engineering Samples. I did see one listing for what they claimed was a QFSA E5-2658 v3 2.20GHZ (ES), but I can find no data to support this as accurate. Others have listed the QFSA as a 2.2GHZ E5-2670 v3. I do not believe it is a 2658, but rather an early ES for a faster 12 core/24 thread E5 Xeon, quite possibly the 2.3GHZ E5-2670 v3. But enough on Intel\'s nomenclature and design process. This particular CPU is amazing, as the benchmarks I\'ve included, will show. What they do not show is how stable it is, and how cool it runs. I have never seen anything like it in my 30+ years working with computers. Power draw is very low, with Vcore running below 1v almost all the time. And load temps range from the low 30s centigrade to the high 40s. I have run stress tests that didn\'t even get it into the 50s!It is running on an MSI X99 Gaming 7 mobo right now, with the latest bios. Had absolutely no issues, just dropped it in and ran it. I\'ve had this less than a year (about 8 months). I just do not need all this computing power anymore, as I am not working with 10-15 VMs like I was when I got this. It has been water cooled since I got it, not that it actually needs it as cool as it runs. But I had the cooler, so I used it. This thing is just a brute. I am a power user (no gaming but lots of hard use) and this thing has never disappointed. Obviously its single core speed is not all that great, but you really do not notice that. You would if you wanted to do any serious gaming, but for most of us, and especially folks doing CPU intensive tasks like rendering or video transcoding, this thing is very very hard to match let alone beat. I\'ve included several benchmark result images including Cinebench R15 render results, which are impressive to say the least. And as you will see in the CPU MARK Performance Test results, it ranks in the top 99th percentile for all CPUs, including dual CPU rigs. I ran the Ryzen render test and it matched the Ryzen 1700X @ 3.4GHz and the Intel i7 6900K @ 3.2GHz, with all 3 coming in right at 36 seconds. As I say, it is a monster. I want to play with overclocking on these 2011 v3 rigs, now that my scripting work is done and I do not need to run lots of VMs. And this CPU is not built for that. So when I found a deal on a new i7-6800k, well I just couldn\'t help myself. If it weren\'t for that, I\'d happily keep this beast. It has been a great CPU. I do have the 120mm AIO water cooling setup for it. It\'s not included in this sale but if that\'s something you\'d like, or you\'re going to have to buy a 2011 cooler anyway, let me know. I can send you pics and info, and if you\'re interested I\'ll make you a deal on both items.
