Ok so for quite some time now ive been using an older Crt monitor and it was really dim looking. I was really looking forward to replacing it. A while back i replaced my Gfx card with a Radeon Hd 7770 and i loved what i saw. I was running it through the DVI port on the back of the card, and i had an adapter that came with the card so that my Crts VGA plug could plug into it. I was running everything (desktop + games) at 1600 X 1200. All was well. Then for christmas i got a JVC lcd Tv that supported a higher resolution and used HDMI. So i hooked it up and was playing everything that 1920 X 1080. All was fine till i put the pc to sleep. After waking up the pc i played a few games and had no issues. Then i watched a youtube video at full screen and the computer screen went dark. I still heard the audio so i was confused. Shortly after the computer restarted and i got the title of the thread as a message. "Hyper flood transport sync error occured, press f1 to continue". I did that and went straight to the same video. I had no issues. It seems it only happens if i A) wake the pc up from sleep mode, and B) watch a full screen youtube video. I dont know what to say guys. Can i get some help? The rest of my stats are as follows.


Amd Phenom 2 X6 1055t
Saphire Radeon HD 7770 Overclocked Edition
4 GB 1333 Mhz ram
Corsair 750w TX750 Psu
Windows 7 Ultimate

I haven't seen this error message in a long time <grin>. In order of things to do:
update the motherboards bios
check the voltage on your ram and make sure the bios has it set correctly.
If you've overclocked remove or lower it, esp on the HT bus.

What is actually happening when you get that error?

Ive Updated my bios very recently, so i dont think thats the issue. The ram isnt overclocked, and the voltages are the same as the day i put this thing together... so not sure what is going on. What do you think a good Voltage would be? which setting would i change?

I just checked last night, the voltage the ram is supposed to run at is 1.5 V, and its not overclocked. Its currently at 1.6 V on the Bios, and the other options are 1.8 V., something else ( i forgot one of them) and 2.1 V. I also looked at the voltages for the HT and NB. They were both disabled.... not sure what that means. I looked at the options for them, but they were different than these voltages. They were stuff like +15 MVU or something like that, i cant rememeber.

Ok so it doesnt happen only after sleep mode, but its more likely to. It only happens when i go full screen on youtube, and it only happens once for the day. I dont know what its doing, or why its doing it. Help?

Edit: Just ran both Memtestx86 and Video Memory stress Test v1.7, both got solid passes. Looking to run a few GPU and CPU tests to see what comes up, ill report back if i find anything.

Edit 2: Ran a GPU stress test and a CPU Stress test, and im not seeing anything weird in the voltage/heat areas... so im not sure whats up.
