## Description

From the manufacturer

Review: Fantastic CPU for Lab Work - Boot loop cursor resolved - This is my latest review. The boot loop was not due to this motherboard. It was due to AMD 3900X CPU that went faulty. I checked my Antec 750W Power supply, Corsair LPX 16 x 4 = 64 GB DDR4 RAM, 1 TB NVMe Sabrent storage & GeForce GPU on my spare Intel Core i7 based MSI motherboard. They worked just fine. Remaining was just this motherboard and AMD CPU. So I got my friends AMD Ryzen 9 CPU on this motherboard. It worked just fine. I google searched for AMD RMA form, filled it and emailed them with all the above actions I took to validate that my CPU may be faulty. AMD responded over email in a weeks time, then I parceled it to them on given address. I parceled the entire CPU box with Wraith cooler and packaged it properly with bubble paper and Tape. I received my new 3900X CPU in another week. It took 3 weeks but now its working fine. Moral of the story is that Boot Loop Cursor on screen is due to faulty CPU. ###################################### Following was my earlier review. My Rig: 1) CPU - Of course 3900X, 2) RAM - 64 GB DDR4 = 4 x Corsair VENGEANCE LPX 16GB 3000MHz C16 DDR4, 3) Disk - 1 x SB-ROCKET-NVMe4-1TB, Other 5 old SSDs with varying capacities. 4) GPU - Very Old 1GB GDDR3 ATI Radeon Sapphire graphics card 5) Mobo - MSI MAG X570 Tomahawk WiFi AMD ATX Gaming Mothearboard 6) PS - Old Antec EAG PRO 750W Gold 7) Case - Corsair 750D. Experience: I performed some heavy duty installations like Openshift and Tanzu with atleast 5 VMs per each installation within Vmware virtualization using vmware workstation. My RAM got 48 GB used. The CPU utilization did not cross 10% and with Wraith cooler it kept its Temps at 39 deg Celsius. During installations, the Task manager's resource Monitor shows only around 4 Cores in use with 8 to 10% spread across them. Rest of the cores are shown as Parked. Looks like power saving to me.
Review: 3900x making a mockery out of Intel chips! - I absolutely do not regret putting the extra money for this Beauty. High end gaming and video rendering at break neck speeds. Only downside are the temps which can be brought down with good coolers but overall, this rocks!

## Questions & Answers

**Q: Is Intel done for?**
A: Intel is not done for but in this cycle AMD is supporting a single socket standard (AM4 for Ryzen) across multiple generations of processors.  Intel's current socket, on the other-hand, is at end-of-life and it is rumored Intel is going to change the socket soon.   When you combine this with Zen 2's enormous power efficiency and excellent all-around performance, it makes very little sense to buy into a new Intel system for the desktop at this time.

Eventually Intel will catch up, but they will need to do it with 10nm desktop production on a stable socket.   Their rumored 10-core CPU on 14nm won't do the job... it will simply be too power hungry compared to the 3900X.

-Matt

**Q: Can any one confirm that this thing is 499.99 and not 890 dollars this guy wants?**
A: Yes, 499.00, way overpriced at 890 this guy wants , wait, be patient,

**Q: Can it run Crysis?**
A: Thank you for your question. We can confirm that, coupled with other computer parts of equal or higher quality, this processor is capable of running Crysis®, Crysis Warhead®, Crysis 2®, and Crysis 3® at "very high" settings or higher. Cheers!

-Easy Sales USA

**Q: Why is it $750?**
A: Because it’s not just a processor you’re looking at, looking at a bundle. Click just processor and you’ll see a good price
