i put another 512 DDR2 stick in and ????????

mosehn · 24 Nov 2006 at 06:17

i decided to get another stick of 512 DDR 2 ram so it would run games smoother , it seems that the computer restarts a lot soon as its booted in to windows or if i go to launch any Dx9 game , bios says i have a gig and the speed is set to 533mhz in bios , what can the prob be ?

thanks

Are they rated at the same speed?
Have you runmemtest?

mosehn · 24 Nov 2006 at 06:37

both ram sticks are exactly the same , 533mhz
no havent run memtest ,

Are the sticks in the correct slots? On my board I must put them in slots 1 and 3.

mosehn · 24 Nov 2006 at 14:37

dimm 1
and
dimm 2
but ive tried a lot of combinations ,
if i try memtest does that test end or is it ever going ,

Do they both have the same timings? If you set them manually you may be ok.

what set them to diferent speeds even tho there 533mhz?

If it's anything like mine it's a different spd chip on the sticks. Mine is ddr but i think ddr2 is the same and has a spd chip. One of mine says it should run at 3-3-3-8 @ddr400 and the other says it should be 3-4-4-8 @ddr400. I set them manually in the bios to 2.5-3-2-5 and got them to run at 1T and also in dual channel. Before with the bios set to auto they were running at ddr333 abd 4-4-4-12 2T.

If one of your sticks was already set in the bios then when you added the other it may not be able to run at the same timings and so you get the instability/crashes. Worth a try anyway.

in bios it says

4-4-4-12 1T

i really dont know what i am doing with this memory stuff
ive now set them it to
DDR 400 and

127 ns for dimm1
127 ns for dimm2

if that makes any sense

Quick test to check the RAM has same spd timings.

Set BIOS to detect by spd

Insert 1 module boot windows.

Download and install CPUZ run it click the memory or spd tab. Note down the timmings.

Reboot remove module insert other module. Boot windows and run cpuz.

Memtest can also sometimes tell you timmings. and yes it does keep going 24Hrs or so are a good test. But if your just after quick checks 1hr or so will suffice.

Hope this helps.

good reply but my bios dosent have any with spd setting

My current mobo is the only one i have ever had that has the "detect timings by spd" option but that would'nt work for me anyway as both sticks have different spd chips.

You can do what he said though. Put the timings on auto, put one stick in, boot up run cpu-z and check the spd timings in the memory tab. Shut down, take that stick out and swap it for the other. Boot up again and find out the timings with cpu-z for that stick. Put the pair in and set the timings to the slackest stick and see if it boots. If it boots and loads windows restart and set the timings to manual/user defined and try to tighten them up a bit. You may have to apply a little extra voltage. try that and let us know how you get on.

I think that means *auto*

U need to snOOp at the memory via CPU-z, mark down model numbers and the like.

What voltage (vDimm) is set?
