I am upgrading my old Corsair 2 x 1GB RAM (http://www.overclockers.co.uk/showproduct.php?prodid=MY-092-CS&groupid=701&catid=8&subcat=813) to some OCZ PC2 6400 2 x 1GB (http://www.overclockers.co.uk/showproduct.php?prodid=MY-072-OC).

I have an Abit Fatal1ty AN9 mobo.

My problem is that the PC refuses to boot with the OCZ ram in. It doesn't even get to POST. However, when i put the old ram back in, the PC works fine (im on iit right now).

I've tried it with all combinations of the slots, and heres what happens:

1. with 1 OCZ ram stick in slot 1, i get a horrible alarm sound, and the Pc doesnt boot.

2. with 2 OCZ ram sticks in slot 1 and 3, the PC turns on fine, but just sits there. No POST, no BIOS, nothing.

3. With my old ram in slot 1 and 3 (as normal) the PC runs fine, and nothing seems to have changed.

I also updated the BIOS because i thought it might make a difference, but it didn't, and I've also switched the jumper on the mobo to reset the CMOS a couple of times in between various combinations of ram sticks in different slots, but that didnt make a difference either.

After reading many forum posts and trying various suggestions, nothing has worked, but the one thing i haven't tried yet is upping the voltage for the RAM, because i get the impression that OCZ ram prefers higher voltage to the 1.8v default. So I'm about to try that, but I'm pretty woprried since I have to do it with my old ram still connected and it could fry them.

Any suggestions or advice will be massively appreciated because I am totally stumped and confused and after 6 hours of Googling, am feeling very, very tired.....

Up the voltage in the bios then save and shutdown.
Change mem ory and try again. I doubt you'll fry the old memory.
What voltage will you change it to?
 
up the voltage to the spec on the back of the new RAM, u won't kill ** old RAM cause ** only running it for a short time. Also cause DDR2 has better voltage torralence than normal RAM... ( i think )
 
Okay thanks for the replies, I upped it last night with no sucess, then went to bed...about to try upping it some more. Wish me luck.

If i raise it to 2.1V and the new ram still doesn't work, what else could I try? (I'm not really willing to risk frying my current RAM by going above 2.1V...i can't risk buggering up my pc)
 
Yeah I updated the bios to the latest Abit one for my mobo, but unfortunately it hasn't made any difference.

I just returned from trying the new voltage, i upped it to a maximum of 2.1V, but still nothing, its like the whole PC just refuses to do anything when i have my 2 new OCZ ram sticks in. I'm completely stumped as to what else to try, so if anybody can think of anything, please let me know. Meanwhile I'm going to try the OCZ forums, coz maybe a tech guy there has heard of my problem before and knows what to do...
 
Wierd, there is a finite number of IC makers in the world and I am not aware of any IC related conflicts with that MOBO. It could simply be a DOA set, it happens :( Hopefully the OCZ guys can get you sorted. They are usually a sharp bunch of fellows. Good luck.
 
Is it possible to try the RAM in a different machine? It might be the RAM is faulty, it seems like you've tried pretty much everything.
 
Yellowbeard, 'm afraid you lost me with the 'IC', I don't know what that refers to. Or 'DOA set' lol. I've posted on the OCZ forums now, so hopefully they'll have some suggestions. Thanks for the feedback.

And Princey, I can't try it in anoher machine because I unfortunately don't have anyone nearby with a new enough computer. It could be the ram itself i suppose, but it is unlikely, I'd be more willing to bet theres just some conflict with my computer (its not overclocked or anything though).

Hopefully I can get it sorted... Again, if anybody reads this and has any more ideas, please let me know. Thanks a bunch.
 
Sorry, the ICs are the actual RAMs or memory chips on the memory module. In some odd cases, an particular MOBOs bios will have a conflict with some characteristic of the IC. This can usually be fixed with a bios revision.

DOA = Dead On Arrival.

Testing it in another machine is still a good idea to see if they are actually DOA or not.
