Is my CPU faulty? Please help!

[Austin_Dish]

Ran into some issues while testing for post on my brothers new gaming pc, hopefully somebody can figure out what the main issue is so we can avoid multiple hardware returns and shipping costs.

Here are the hardware components we were using while testing for post.

(MOBO) - ASUS Z97-A LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
(CPU) - i5 4690K
(RAM) DDR3 Corsair Vengeance Pro 1866mhz (2 x 4GB)
(PSU) XFX TS 650W 80+ Gold Certified ATX Power Supply

THE PROBLEM: Everything was assembled correctly, 24 pin connector and CPU power connector plus ram was seated in its correct spots A1/B1. I powered up the mobo to test post and the CPU Led flashes red one time and immediately turns off, followed by a permanent red DRAM Led and nothing on the monitor.

I researched countless posts and tested each RAM slot individually with multiple sticks of RAM including new and old (that worked before) and nothing seemed to work, took the cpu out and placed it back inside to ensure it was secured correctly, still no fix.

MY SOLUTION: At this point I figured it was faulty ram or the motherboard was faulty, so I brought his components (i5 4690k & Corsair Vengeance Pro) to my PC and decided to see if the results were similar on my PC.

Here are my components for the test..

(MOBO) - ASRock Z87 PRO3 LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
(CPU) - i7 4770k
(PSU) - EVGA 120-G1-0750-XR 80 PLUS GOLD 750 W

I first tested his RAM (DDR3 Corsair Vengeance Pro) with my CPU (i7 4770k) and it booted correctly, right to the login screen. So the RAM can't be faulty.. checked the bios and both sticks were recognized in their correct DRIMM slots.

After that I placed his CPU and RAM inside my PC and booted up and got the following message..

"The following Channel memory did not pass CPU memory test, Please remove the memory then plug again. Channel A"

I then removed the ram and tested the slots with my ram and got the same message, tried the other slots and still the same outcome. I pressed F2 to enter my bios and saw that 8GB was detected on one channel, channel b1.

I'm beginning to think his cpu is faulty, but i'm hesitant because so many people say it's most likely the mobo or ram failing but neither seem to be the issue because my motherboard works fine and the RAM works with my mobo but his CPU seems to be the problem.

Can anyone confirm my issue, or possibly shed some light on my problem? It's been a long day trying to come up with a fix or any type of solution/conclusion.

Thank you for reading!

well you could send the cpu back and just replace it..exchanges are very easy and they honor it without hesitation usually. did u look inside the mobo for bent pins either on cpu and or mobo. a bent pin could make a difference but usually it wouldnt boot. it definitly sounds by what you explained a cpu issue since in your comp did the same with error message.
just to make it 100 % sure of cpu..put your cpu in his comps mobo and ram see what happens

We've ordered a new mobo and replacement cpu with priority 1 night shipping.. hopefully this will resolve the issue considering the RAM is not the problem, I am still curious why we ran into this problem.

yeah it must be rare one because i post here allot austin and people are quick to respond usually, they must be stumped...why do you think it needs a new mobo? just being safe right? its a good idea..
i just built my own PC first time with for gaming.i got the i5 4690k OC 45 @ 2.10 ... evo 212 air cooling.. grabbed a krait sli edition for my 970..gonna its all sli ready got a 750 psu evga supernova..
anyway your gonna love that i5 its a beast.. good luck

Probably memory controller on chip. Intel rma is quick and painless.
