#Intel desktop board dh87rl with pc3l crack#

There is no sign of a crack in the old motherboard, but it could be in the middle layer of the PCB and not visible from the outside. I removed it and installed my Core i5, and it’s all good once again. I tried the Core i7 4770 first, but again, only got a repeating pattern of blinking lights on the front of the case, but no boot. Once all my pieces arrived, I gutted my old case, put the new motherboard in the new case together with all the drives and other bits and pieces. I also ordered a new case, since I wasn’t all that pleased with the mini-tower case I had. On the assumption that the motherboard might have developed an issue because of the inherent flexing of all my changing around of CPU’s, I ordered a replacement, another Intel DH87RL (they’re getting hard to find). I checked all the power connections, and when I unplugged the 2 X 12 main power connector and plugged it back in, I could feel movement in the board itself that I’ve not felt before in any previous builds I’ve done. I checked all the drive connections and tried again, but no go. The only light that came on was the power indicator light.

Again I replaced the Core i5, but it still wouldn’t boot. I got basically the same results, a repeating pattern of blinking lights, no signal on the monitor, and no boot. So I ordered a Core i7 4770 and tried that. My experience seemed to support that conclusion to some degree. I did further research online and found a couple of posts on forums stating that since the DH87RL was not an unlocked board, the unlocked Core i7 4770K was not compatible. So I replaced the Core i7 with the original Core i5, and everything was back to normal. There were multiple courses of repeated HDD-activity-light-blinking in the same pattern, but no boot, no signal on the monitor.

Compatible, but not really.Īfter making the change, it would not boot. I settled on a Core i7 4770K after going through Intel’s compatibility wizards for the motherboard model and the CPU model. Not that I really need it with my typical usage, I just wanted it.

For some time I have intended to upgrade the CPU on my Intel DH87RL motherboard from a Core i5 4670 to a Core i7 with multi-threading capability.
