How Did We Get Here
Lately, I find myself making attempts to find broken or untested hardware on the cheap. I don’t go randomly selecting things that have no hope for repair; I search listings looking for clues that may indicate what the issue is before I start looking at prices. When I find something I may be able fix, and the price is right, I’ll take the chance.
There have been a number of such purchases lately, with the most success coming from motherboards. There have also been a few misses, mainly with graphics cards. The latest video attempting to repair a motherboard is here, while the extra details here. It doesn’t always work, sometimes you get a bad CPU and it’s difficult to tell on which component to lay the blame
This particular case is a Z390 Phantom Gaming 6 from AsRock. It’s a quality board and the price was right. The seller did disclose not testing the board due to bent pins, and they could be seen in the pictures. I set my sights on a cheap processor to test with and all in with shipping I was in for about fifty bucks.
Testing
The pins were tedious, but repairable. After about two hours of meticulous work, it was ready to test. My new Celeron G4900 was actually a used CPU, but the whole set up worked. The two cores of the Celeron aren’t a great match for the motherboard, but it’s a good starting point. At the time of this writing, an upgrade has arrived.
I have a suite of games I normally test, and these worked with one exception. Borderlands Three stayed on the intro screen, the entire forty-five minutes I let it. I point that game out because Borderlands Four actually did work on the new set up and the results were predictable. Neither the processor nor the graphics card are suitable for playing this game but it turned in a respectable 20-24 frames per second on low with upscaling.
I was able to update the bios, and run other games including Call of Duty, that requires anti cheat. The results weren’t great, barely reaching 30FPS in most situations, but we are ready to move on to the next phase. That is where things took a turn.
Failure
Having tested the Celeron, I looked for a more powerful processor and arrived on an 8700K with six cores and twelve threads. Ideally, this would rival newer budget type setups and I looked forward to it. This, however, didn’t go as well. The 8700K doesn’t post, even with a new BIOS, clearing the CMOS, and trying different RAM placement. The motherboard has a debug indicator that stays on ’00’ with the fans running full speed.
I tried several things to troubleshoot and have to believe that the CPU itself is bad. This presents me with two options. I can buy another board to test, whether its just a board, or an old Optiplex, or I can get another CPU. I have plenty of ‘broken’ prebuilts, and found a ninth generation i5, that should be here this week.
If the issue turns out to be the 8700K I’ll have to file a claim, but the platform I purchased on has a great buyer protection program, so I should be safe. If the issue is the board, it complicates things just a bit, because I can’t completely rule out the processor. Getting a new board means all new tests and by the time I am able to verify the 8700K is the issue, it may be too late to file a claim.
So, What’s next?
That was actually dictated by more shopping for used parts. Ideally, a score would have been a cheap office prebuilt with an eighth or ninth gen processor. That allows me to check both parts in question. What I’ve found so far is an i5 9400F, which allows me to test the motherboard. If it arrives quickly enough, I can at least test the three sock theory.
Okay, for those unfamiliar, it’s a dark laundry room and you have two different color socks in the dryer. How do you pull a matching pair? You have to pull at least three to take into the light, two of the three will be the same color, possibly all three. Having three CPUs helps me reasonably assess if the problem is the processor, or the board.
This won’t be the last stop for the 8th or 9th gen set up. It’s not a current platform, but collecting at least one working platform over the past several generations helps me test a variety of conditions. It allows me to test a variety of games, Linux distros, applications and even hardware for compatibility. I will eventually get another motherboard, but for the time being, I’ll go with what I have.
I spent as much time troubleshooting the new CPU as I did fixing the board in the first place and there are better things to do with the set up, even if I can’t get my money back. I’m still happy with the board and the initial testing and when I get the i5 to test, there will be a video and of course, a blog.
