Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA 1155

I had waited almost 2 years to get this CPU! And, the time came when I finally broke down, and bought it. Searched, and searched, and found a buyer that was decent in price, and wasn't used--not that if it's used it's bad, but I really wanted a new one, and this was a very special build for my DragonSlayer II! The seller sold it quickly, and packaged it up really well. Thanks!

Pleased with my purchase. Shipping was done very rapidly, packing was excellent and product is great.

The extra cache and HyperThreading made multitasking smoother and even improved frame rates a bit. Will prevent me from having to do a full upgrade for another year (or more).

Working great i have it water cooled no problem gaming 4k

This is the 4th time I've tried to leave this review...No post with more than 1 stick of ram.System build-I7 3770k (previously i5 2500)Gigabyte z77 ud5h moboGigabyte hd 7970My brother wanted a gaming pc, I had a shelf of parts from customers computers they donated. Either cause the system was old or the motherboard/gpu needed logic board repair that i don't have enough experience in to offer as a repair service. So I used a known good motherboard from an old computer and a cpu out of a Dell system with a compatible cpu and built the system around my old gpu that I had managed to revive.He wanted to upgrade it and either stream or record his games. I never had issues with the gpu he has so I figured the cpu/ram could use an upgrade as the one I gave him couldn't overclock. My system has a xeon x5675 so I knew that the cpu difference would give my system an unfair advantage. That and the larger cpu cache size. So I looked around found a cheap i7 3770k on Amazon and got him some more ram as well as a scythe Mugan 5 cpu cooler so we could do some minor overclocking.However after installing the new cpu and cooler. The system would not post.Checked firmware. No further bios update available.Reset bios to factory settings, maybe there was something I missed or didn't pay attention to. Still didn't help.Swapped cpu cooler back to stock intell. NothingTook out all ram leaving one after reinstalling the scythe cooler. System boots up and posts. Clears windows no problem.It continued to post regardless of which slot I used for the single stick of ram. And regardless of which stick of ram I used.Now im thinking maybe its something stupid like a screw stuck behind the mobo in the case. So I continued all further testing out of the case.No change. System will not boot with more than one stick of ram regardless of which slot that one stick is in.I've been doing this a while so I went back to the old i5 to verify that the mobo was still good. And the system goes back to normal with the i5 installed. No ram issues even with max memory supported installed in dual channel on 4 slots.I figure I overlooked something with motherboard compatibility so I ordered a different motherboard I have experience with the i7 3770k working on as it was a friends computer. Lmao come tho think of it its an identical build with the same gpu.After swapping out the motherboard the system still persisted to have the issue again, only with the i7 and not the i5. I look at the i7 pin pads. And notice the 5 that are responsible for the memory controller circuit seem worn through like someone messed with the screw on the motherboard and over tightened the lga socket. But we have never messed with either and neither mobo has a stiff lever beyond what is normal for this socket.I checked the i5 and the pad damage is not there.I have tried 3 times since this purchase to get a refund or a replacement to no avail.

Not much to say about an older CPU but that its a solid performing CPU to max out the Z77 chipset.

took out my 3570 and popped this in and it worked. Been using it about a month or two and definitely sped up my computer.

Best for gaming with low end PC
