RAM problem?

i've just acquired another two sticks of corsair 6400C4-PRO ram

this would be in addition to the twin sticks already installed in the machine.

when i turn on the computer it will either sit there with a blank screen, or the internal buzzer will sound before it can POST (the back display reads detecting DRAM)

i have the machine currently o/c to 3.0Ghz, but it won't POST at those settings or as stock standard.

the machine will also not boot up with either of the new sticks installed (ie: either on their own, or with one of the older sticks.

should i try to return them, or is there something else i can try beforehand?


Machine stats:
e6600 o/c to 3.0GHz
Asus Striker Extreme
2x1GB Corsair 6400C4PRO ram (+2)
XFX 8800GTX
 
yeah, except for two problems....
1) it wont even boot far enough to get to the BIOS, with or without the old memory (so i dont know how a boot disk will help me there)
2) the computer doesn't have a floppy drive
 
yeah, thats what i meant by stock... ie: standard settings for the MB
Did you actually go and clear the CMOS, then load "standard defaults" or "failsafe defaults" or equivalent, then save the newly changed settings? Just going in manually changing individual settings can sometimes be problematic.

If you've done that, I'd go for getting them exchanged under warranty.
 
yeah, i tried it both ways (the CMOS reset switch on the board, and by reloading "Factory Default"
ah well, i guess i'll just have to wait for the shop to get back to me now 🙁
 
Try booting with 1 or 2 DIMMs, manually set the memory voltage to 2.1v, power off, install 4 DIMMs and see what happens.

If this fails, try testing each individual DIMM with Memtest for 3-5 passes per DIMM. Do this with the timings set manually to 4,4,4,12 and the voltage at 2.1v.

Also, can you give me the information from the stickers on each pair of memory.
 
uh, sorry, i just sent the RAM back to techbuy yesterday for replacement...
but with respect to memtest... thats the program that needs to be run before you load windows (ie: seperate boot) right? is it possible to boot with a CD? (since the computer doesn't have a floppy drive in it). but even so, i did try the modules one at a time in slot A1, and neither would let the computer boot up to even access BIOS, let alone load an OS (even if it is memtest)

also, that memory test feature that windows vista comes with - "Windows Memory Diagnostics" (press DEL just before loading windows - ie: where you pressed F8 before to go to boot menu), is that similar to memtest, or is it testing the hard drive instead?

all i remember of those stickers is the new ones were acc70-something while the old ones are acc61104631 (thats how i told them apart)
