memory problem?

Hi heres my set up



Elitegroup gf8 100vm m5 motherboard

Amd phenom z3 8450 triple core cpu

2gb 800mhz ddr2 memory



I bought this lot as a bundle from maplins so it should be compatable



Heres the problem, after building the pc i powered up into the bios and set my first boot device as the dvd drive so i could install windows then i exit and save and then the screen goes blank the pc is still powered up, fans spinning ect.

I removed the battery from the board to reset it and tried again this time it started ok but in post i get this message "dqs training failed on previous boot, reverted to slower dram speed"

So i hit f1 to go into bios and after setting dvd drive as first boot device again i'm back to square one with a blank screen.

I've since tried some different memory which got me a bit further, i was installing windows and it just stopped when formatting the hard drive and when i tried to restart i got the same blank screen again, i keep having to remove the battery from the board to get it started but keep getting the same message about the "dqs training".

Also one time when i was in the bios it just shut down

Not sure what the problem could be i thought maybe a dram timing issue or maybe i need a bios update, i contacted elitegroup but 4 days later still no reply.



Regards

Paul

This error seems to be caused when the speed of the memory that's been used is too fast. Typically the board has auto-decided the memory to run at a speed that's too fast so it'll lock after coming out of the BIOS screen. Clearing the CMOS clears the status so the machine will post because it doesn't know any better. Manually setting the memory speed to 800Mhz in the BIOS should solve the problem. Some boards display this as DDR400 speed which is the same thing as the figure is doubled. This is not unique to ECS boards, it's happened on other brands as well.

There was no 800mhz option so i set it to 400mhz and managed to get windows installed on the second attempt but its not running well at all, the graphics are really slow to respond and it keeps crashing ( the screen goes blank but the pc's still running) :)
Then i have to pull power lead out to shut down and take the battery out of the board to reset it or it wont start up.
I still get the message "dqs training failed on previous boot reverted to slower dram speed" when i do manage to get it started.

Possible board issue.
Rather than spend time tracking it down, far easier to take it back to Maplin as faulty stock and get a refund.
You can get better and cheaper bundles from elsewhere - Maplin is ridiculously expensive for computer peripherals.

Don't ever do this - just press the power button in and hold it for 3/4 seconds and your machine will power down AFTER lifting the heads off your discs.
