Hello Forum, I have a problem and I can't find any information that is exaclty like it anywhere, so I decided to post it here to see if any ideas come to my help.
I got a Mac Pro 4,1 flashed to 5,1 and upgraded to 3.46 cpu's with IHS removed. Now, before I paid the guy i tested it running an Apple Hardware Test (short one) which resulted in no issues, I used Hardware Monitor app to see temp and voltage, etc. All seemed good, so I went ahead and paid the guy, took the computer home and went to bed. Next day, before booting it up, I decided to take the side panel off to clean it and install a new copy of OS X. And here is where the problem showed up, when I booted from USB and noticed that both red leds next to the CPUA & CPUB where flashing like a hard drive activity led would, first time I have ever seen something like this. They flash for a while, fans rev up and then things seem to go back to normal. I decided to run an extended hardware test and that is were I got a BOOSTA-1257 error, and for what I was able to find it is related to the CPUA Heatsink fan, but I can see it working just fine and also using fan control I was able to increase and decrease its RPM with no issues.
Now, this guy did tell me that he did the de-lidding of the cpu himself (IHS removal) but did not tell me that the tray was not the original and that he had bought it from someone else, my bad for buying something of off craigslist (price was just too good) so I Am not sure what could be really wrong with it.
I've been thinking about taking the tray out and taking both cpu's out, cleaning the heatsinks, applying new thermal paste and putting some new silicon thermal pad and see what happens.
Have any of you seen the red leds flashing like that before? I get that if there is and issues it usually flashes to let you know or stays lit, but never seen them flash like that before.
Any help would be appreciated it.
