New memory

[beesagtig]

I have always had 2X1gb sticks of this http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_8500_sli_ready_edition_dual_channel

and today got 2X2gb sticks of this http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_8500_platinum_4gb_edition_dual_channel

and now my system is really unstable...

any ideas on how to stabilise it?

duh, bios udpate? reinstalling the dimms one at a time?

 

[beesagtig]

it runs fine with just the 1gb sticks in it also runs fine with just the 2gb sticks in so the dimms are all fine but not with them all in. Would a bios update fix that?

 

[vypher]

Yes, I believe a bios update should fix it.

What are the SPD settings for each kit?

You might not be supplying enough voltage for one kit or the other and/or are running with timings that are too tight for all four dimms.

And running 4 DIMMs needs more voltage to the Northbridge.

A BIOS update won't really do a thing, it'll be one of these things above ^^

Thats good because i dont really want to update my bios:S

ive got the timings at 5-5-5-15 which is right for the sli ready but should be 5-5-5-18 for the platinum. is that ok?

all dimms are at 2.1v which is .1v too low for the platinum.

i dont really know anything about the northbridge

 

[Darknova]

northbridge voltage will be an option in your BIOS, generally under voltage options (maybe overclock section? someone who has that board might be able to help more).

I suggest you up the voltage to the DIMMs by .1v, then do the same for the northbridge. 4 sticks taxes the northbridge more than normal, so it needs more voltage to be stable

 

[beesagtig]

cool so just up the north bridge bit by bit until its stable?

Yup, but like anything, don't go too far
