Recommended Posts

I have been having stability problems with my 6400c5 which are really confusing me now ! ican run windows and low load apps fine but as soon as i run somtihng mem intensive like orothos or mem test i get a hard lock in afew minutes. I have yet to try the sticks out on there own but will do this asap . any ideas why this is happening , meme test ran fine for the first part then just locked no errors reported just a full lock up !

ok just ran mem test again and it passed an entire loop no locks not even an error !

looks like i may have some sort of cooling issue or a problem else where.

 

but just for ref mbo gigabyte ds4 F3 bios (cures the cass setting issues) , vdimm +.1 volts giving 1.9v all others are default other than i have backed ram fsb off to 1:1 so 533mhz

Hello,

I have a ga-965p-ds4 F6 bios and 2GB of TWIN2X2048-6400 memory set to 1.9v. I have a similar issue. The memory passes memtest86 and works ok until stressed (game or video transcoding) when it locks up. After a re-boot it will work indefinitely until the machine is powered off. When it is re-started I the problem recurs. Any suggestions ?

Thanks.

Try the Voltag set to 2.1 Volts or +.3 Volts!

And if you have a setting called ‘Write to Precharge delay’ in the BIOS (same page as for latencies) please try and set it .from default 10 to 15

 

The voltage makes no difference and I can't change precharge delay.

 

I ran one DIMM for 2 weeks with no problems. I replaced it with the other, same slot, same settings and within 30 mins of restarting the PC locked up.

 

Memtest86 and the Microsoft memory test both report the memory ok. After rebooting the PC is fine until it is powered off. Next day within 30 mins of startup it freezes again.

I also have the Gigabyte GA965P -DS4 motherboard and can run one stick of memory for days without problems, but if I install two sticks of memory, I get spontaneous reboots after a couple of hours.

I have tried two different brands of RAM and EXACTLY the same thing happens.

 

I think this motherboard has some serious issues. :biggrin:

Some users are saying the latest bios is helping those boards ( F7 I think? ). If you don't already have it, give it a shot. If it does not help, I'd suggest an RMA on the MOBO.
