guys im having a memory issue atm

been running 8gb just got another 4gb its hynix, HYMP5512P72BP4-Y5 AB-A 1gb

the board will boot but it comes up with gnu grub which ive never seen before

give me the option to boot to ubuntu or run memtest

if i select ubuntu it just reboots and goes to the grub again

choosing memtest its runs for several seconds maybe then reboots...

but i noticed as it was running memtest the the ram speed is 533mhz and the timings are 4-4-4-18 i think

where as the ram ive got is 667mhz and 5-5-5-15...

could it be this hynix ram cant run at this speed/timing but the other 8gb can?

i cant get in the bios to change it

and why wouldn't the bios automatically change it?

if i take the battery out to clear it will that work?

thanks
