Hey everyone. I'm having a problem that I can't seem to fix. Around the middle of last year, my computer started shutting down while playing games. At first, it took an hour of playing before it would shut down, and then it was 30 minutes, then 10, and eventually only five minutes. Every time it gives me the message, "Hyper transport sync flood error occurred on last boot." I had never heard of this before. I began searching, and I found some people saying that you should update your graphics card's drivers, update your BIOS, and make sure your computer is well ventilated. I've done all of this and it continued to happen. A friend recommended that I watch my temperatures and check the GPU's fan while playing. We found that my graphics card was idling at a high temperature, and it continued to rise while playing until it reached 90 degrees, at which point it would shut down. On top of that, MSI Afterburner was getting a ridiculously-high reading on the fan's RPMs. This led us to believe that the card was bad and I should replace it. So I did, and the problem continued.
Now I've done more research, and I've linked the problem to the Northbridge. I've heard that when the NB clock speed dips below the HT clock speed, you get a hyper transport error. I read that I should raise my NB clock so that there is a significant difference between the NB and HT clock. When I went into my BIOS, I found that there wasn't an option to change the NB speed like someone else was showing. I decided to lower my HT to 1.8GHz and test it out. After doing so, I was able to run a game for 30 minutes before it shut down. This is actually a huge improvement from the five minutes that I was getting on the same day before I lowered the HT clock.
So what I'm wondering is if there's any harm in lowering the HT speed again, and if I do, will this fix the issue? If not, what should I try next? Here's all of the specs that I feel relate to this. Let me know if there's something else that you need to know:
Processor:
AMD Phenom II X6 1035T (6 CPUs), ~2.6 GHz
Core Speed: 799.96 MHz
Bus Speed: 199.99 MHz
HT Link: 1799.90 MHz
Motherboard:
ECS A880LM-M
Chip: AMD 780G
Southbridge: AMD SB700
Graphics Card:
eVGA GeForce GTX 750Ti SC
And here's an image from the BIOS which provides some more information, including the options I have.
I really don't know much about this stuff, so please let me know if I need to include anything else.
