Rusting In Peace :
I've had a Google around for this and the best I can find is:
■
This thread (last post) where the guy managed to get rid of the issue by reseating his GPU. I'm sure you guys have but perhaps look even closer at how the GPU is seated in the motherboard.
■
Supposed compatibility issues between HIS cards and this motherboard.
Unfortunately both of these are pretty weak. It sounds like the both of you have been persistent in attempting to solve the issue. Perhaps raise an issue with ASRock directly or return the motherboard as faulty?
Well, the short version is: I got it working.
I had the RMA in hand and had all but picked out my replacement board but I thought I should give it another try. I'm now posting from the new machine. Here is what I did for what it's worth.
- removed the cmos battery
- removed the heatsink and CPU. Pin 1 was correct and seating appeared good.
- inspected all socket pins with a magifying glass and light, no damage found.
- I noticed that I used too much thermal compound. A small amount had touched the substrate. I don't know if this could mess anything up but since it may be conductive I carefully removed any excess. Inspected the LGA arrray also, no issues.
- carefully replaced cpu. I noticed that the lever makes a disturbing crunching sound and takes much force. I guess this is correct because it works but hey whatever happened to Zero Insertion Force sockets.
- replaced cmos battery. I did clear the cmos many times before this using the jumper and the handy clear button the back pane but had not pulled the battery. Not sure why that would have made a difference but should have done it since it was easy. It was probably out for 15-20 min.
- placed heatsink on cpu _without_ tightening the base at all. Would never run like this but it should be ok to check post for a few seconds.
- installed one stick of ram in the first slot, closest to cpu. A1 I think.
- installed vid card. I believe I used different molex connectors on the card power pin that I did the first time. I did not note the original molex I used. Just saying in case there was a voltage issue to the card with the original connectors. I did not have a multimeter to check the voltages.
- made sure it was well seated
- had the mobo outside the case still on insulated pad.
At this point it posted. I tightened up the cooler carefully and added things one by one and it continued to post after each. Finally got everything installed and no problems.
As you can see I changed more than one thing at a time so I can't say for sure but it has to be one or more of these:
1. Maybe I had overtightened or unevenly tightened the heatsink base screws from the bottom of the board. I have a very large tower cooler so i didn't want to take any chances. I did try to do each screw evenly.
2. reseating the cpu? It looked fine to me when I took it apart but who knows.
3. clearing the cmos by removing battery
4. reseating the vid card
Thanks Rusting In Peace and feel free to give me "weak" suggestions any time.
Eagleye I hope you get yours going. Thanks for letting me butt in. Let me know what happens.
