Hyper Transport Flood Sync Error (FOXCONN A7VMX-K)

post #1 of 21
Thread Starter 
Specs:


* AMD Phenom II X2 550
* Foxconn A7VMX-K motherboard
* 4GB DDR2 memory
* ATI Radeon HD 5750 graphics card (1GB on board memory)
* Windows 7 Home Premium 64 bit edition



I bought my PC about 4 weeks or so ago from PC World (I know, would have been better off building my own, but that isn't the point here).

I started getting the Hyper Transport Sync Flood Error when playing certain graphics/processor intensive games (such as Fifa 11, and Dead Rising 2). Always randomly, never at a specific time, my computer will restart without warning, displaying an error stating that a "Hyper Transport Sync flood error occured on the last boot". I also just got the error when watching a You Tube video at 720p resolution full screen.

I havn't done any overclocking at all to my computer, apart from the boost that either PC World or ADVENT did in the factory. A note came with the PC saying that they had overclocked my CPU from 3.1Ghz to 3.4 as I have a black edition AMD cpu. So basically the computer is at it's factory settings, the only overclocking has been done by the company.


This error is very annoying and I feel like I shouldn't get this sort of thing when I buy a new PC. I bought it because the specs were up to par with the sort of gaming I wanted to do with the PC. However I can't do my gaming when the computer decides to randomly reboot and display the hypersync flood error all the time.

Here are two images from AMD OverDrive utility, to show some values that aid anyone willing to help me with this error:








I'd like to add that I checked to see if I had the latest BIOS version for my mobo. Well the version on the vendor's website had a date that was earlier than the one indicated on my system, so I assume that means I have a more up to date version of the BIOS? Unless I need to download the one on the vendor's website? Hmm.. Advice would highly be appreciated. I'd rather solve this myself than take it to a computer shop and have to fork out for them to repair it.

Thanks!

I'm having a similar issue. I suspect it could be your motherboard or CPU.

try lowering your NB multiplier from 10x to 9x

I think I might have fixed the issue

I lowered the NB multiplayer to 9x as suggested, and also bumped up the voltage to the CPU by two increments (+50mV).

I've now had 5 games of Fifa 11 in a row without a crash which is way more than I would normally get. At most I would get 2.5 - 3 games, so I think it might have worked!

Thanks for the help ironman, I think it was to do with the HT speed exceeding the NB speed, and so the 200MHz difference is enough to eliminate the error now.

But also the increased voltage to the CPU probably offset the increase in CPU speed that PC world overclocked before I bought the PC.

Try these two things Markeh, after 4 weeks, I think it might have solved the issue.

Will post again if I get another crash within the next week or so. If I don't, I suspect it has solved the issue!

Its voltage related, atleast it was when I had the problem.

Low Vcore. Your CPU/NB & HT Link were @ 2000 ,so dont need to lower them

I just got another crash, so i'm going to try raising the NB back to 10x and raise the cpu-nb voltage by 1.25V to see if that helps. I'm not understanding what this Vcore is


This is what the values are at now in BIOS:

CPU voltage [+50mV]
CPU-NB voltage [+30mV]
HT/SB voltage [+30mV]

Multiplier is also back at 10x.

Are these voltages enough? As I say, I don't really know by how much they should be raised etc.

Thanks!

try 1st,hope u fix it...
HT/SB just give it stock due now try playing with CPU & CPU-NB 1st, b4 upping the SB..
