HyperTransport Sync Flood Error

[ChewyBrownSuga]

so yeah every time I try to play a game my computer goes to a black screen monitor shuts off and my computer does a reboot and it says hypertransport sync flood error

What do I do?

 

[btarunr]

That is caused by:

1. Too high of an OC without the ample amount of CPU volts.
2. Plain, not enough CPU Volts at any speed.
3. Possible Bad power supply.
4. Motherboard with very high amount of VDroop which ultimately leads back to "Not Enough CPU Volts". This will reveal itself with a load on the CPU. Maybe not during typical use. Could just be that the motherboard has CPU power providing issues as well (Good power from PSU but motherboard wastes the power before reaching the CPU).

Respond accordingly. MSI boards seem to be particularly affected. Start with upping DDR3 voltage a little (+0.1V steps till you reach 1.8V).

how would i adjust the ram voltage?

how would i adjust the ram voltage?

System BIOS setup. Reboot, increase 0.1V, see if it solves the problem, repeat till it reaches 1.8V, if it doesn't. Avoid crossing 1.8V.

Is your RAM voltage set to Auto? From googling the problem, it seems some boards occasionally don't give ram the juice it needs. Set it to the spec voltage in BIOS and see if it works.

thanks trying now

2.0v will cause damage, according to AMD, hence his recommendation.

I see you are using an unlocked 720BE...could be caused by the bad core. Early "unlock" bioses exhibited this behavior as well, when disabled cores were re-enabled.

That said, a bios update may be in order as well.

 

[DonInKansas]

Good call, Cad. I saw a couple areas where MSI boards are notorious for this.

 

[cadaveca]

ASUS too, early unlock bioses sucked all around...

 

[ChewyBrownSuga]

ok so i tried to adjust voltage and it was all grayed out so i just loaded the fail safe settings

 

[DonInKansas]

YOu may have to change a setting from auto to manual to be able to tinker with them. I know little of MSI bioses, so you might poke around.

 

[btarunr]

If your BIOS setup lets you choose between "Auto" and "Normal", choose "Normal". Or find out what are the default voltages for your memory, and set it manually.

 

[ChewyBrownSuga]

So i couldn't adjust the voltage in bios but i did download AMD OverDrive which lets me adjust the voltage without the bios

I bumped the volts up to 1.6 in the memory VDDQ and I'm still getting the problem what should i do now?

ok updating system specs

So I moved the volts down to 1.5v, going to give it a try now

Still getting the crash at 1.5v

This attitude is not needed, reported. Flame baiting is against forum rules.

running with the 4th core unlocked, or no?

2.0v will cause damage, according to AMD, hence his recommendation.

that sounds strange to me... doesnt they can easily take 2.4v and more?
i mean, i had it about 2.4v a relatively long time, with my dominators, and that doesnt seemed to be a problem. from what i know, AMDs IMC´s are relatively tough, compared to for example, an i7

No when I unlocked the 4th core I would get temp reading problems

I will give what you said a try now Wafer

Tried taken my Memory VDDQ to 2.407 and it crashed

Yeah, I hear ya..I'm just relaying what AMD specified, nothing else. I could provide a link, if need be, but I know you can find it too.

 

[ChewyBrownSuga]

My memory frequency is 533.00MHz does that sound right?

i didnt found any official info, but a bunch of people stating they had no problems till now... But maybe youre right, can you provide that link?

 

[cadaveca]

Yep!

I don't think it's the mem..it's either the bios, or the cpu. I've dealt with this issue on the GD-70 with my 720BE, as well as on ASUS CrossHair 3. I cannot remember which GD-70 bios fixed it for me though...typically I was running into this when clocking teh cpu over default.

I suggest you clear you bios, and start over. Maybe the board is inadvertently using the bad core.

System Memory voltage adjustment (5)
This one can also have two sliders (depending on the
motherboard that is being used). “Memory VDDQ”
(memory core voltage) that defaults to 1.8V is the slider
that should be adjusted in most cases. The other slider
(Memory VTT) will adjust automatically according to the
VDDQ slider adjustment. Normally the VTT level should
be 50% of VDDQ level.
Boosting the memory voltage can improve System
memory performance tuning.
PLEASE KEEP IN MIND THAT MEMORY VOLTAGE
ADJUSTMENT IS THE MOST DANGEROUS VOLTAGE
RAIL TO ADJUST AS IT CAN DESTROY NOT ONLY
THE MEMORY BUT ALSO THE CPU AND CAN
POTENTIALLY DAMAGE THE MOTHERBOARD.
ANYTHING BEYOND 2.0V VDDQ IS HAZARDOUS AND
CAN DAMAGE THE CPU AND THE MEMORY
MODULES.

That said, there are other settings you can adjust to comphensate for higher voltages. It's just that the termination of the DIMM volts, to CPU/NB volts, that extra juice has to go somewhere(say, 2.2v to 1.1v of C3), and if not set right, the NB will get it, causing damage. Some bioses(DDR2 most specifically) already account for this. Memory and NB volts need to remain within specific ratios, so obviously, the easy way to deal with this is to up NB volts.

 

[ChewyBrownSuga]

downloading the newest bios now

now all I have to do is find my thumb drive.......

 

[Velvet Wafer]

Yep!

as far as i get it, they mainly talk of the VDDQ of ddr3...with ddr2 the proc is able to take up to 2.3v, because the board accounts for this,so certain voltages cant be set too high.
that would be the answer to my question ;-)
i believe 2.0v is pretty hazardous to ddr3 overtime,even with an lga 775. i wouldnt try it

 

[cadaveca]

D9GTS or D9GTR demands more than 2.0v. WAAAYYY more. HCF0 scales best to 2.05v

And like I said, I am not the info source, just the messenger.
