Right, I'm giving my PC a small boost to get it up to scratch for Vista, I've just bought a new Seagate SATA HD, but I want to give my system an extra 1GB of RAM to bring it up to 2GB in total.

Now I remember a while ago reading some nasty rumour that Nforce3 Ultra motherboards will only accept 4 sticks of RAM if it's not double-sided. Is this true? At present I have 2 512MB sticks of single-sided RAM running in dual channel. Will I need to make sure that the next 2 sticks are single-sided also, and if so where can I buy them from that will guarantee them to be single-sided? The last time I had to do this I think I had to order over the phone from Crucial actually.

Reps for any help given :)

PS Also, why does my sig not show up properly in IE7?

no nforce 3 take all 4 banks with double sided, you just have to increase the command rate to 2T from 1T else it'll crash on boot up :)

Will I still have to increase the command rate if it's all single sided? What about if 2 are single and 2 are double?

Also, will there be a performance hit from doing this?

Arse then! Do I just increase the command rate in the BIOS? Also, what kind of a hit can I expect? Shall I just stick with 1GB and buy a Creative X-fi card instead? :p

yeah increase it in the bios. It's not much of a hit though.

So what do you reckon? Will I see much benefit from running T2 with 2GB compared to T1 with 1GB under Vista? If not I might just get an X-fi as I currently use on-board sound which isn't great and I might get a small performance increase, though that's debatable.

EDIT: I just bought an OEM Xtreme Music card for £60 from dabs... :)

Well, I just slotted in the new X-fi card...

It's awesome. I never thought I'd hear so much difference, my speakers aren't even anything special just bog standard 2.1. I'm well impressed with this :)

There would have to be something wrong with your hearing if you didn't notice an improvement over any other sound solution for pc's :)

I've just had a look at my settings and I'm running at T2 any way! On the downside, it's really unstable when I try T1, even with just 2 sticks of RAM. Will it still be ok with 4 sticks at T2?

yeah it'll be fine at 2T with 4 sticks. I ran it at 2T with 4 sticks until I upgraded to a core 2 duo :)

Cool. Any idea why it should be unstable at T1 with just 2 sticks? Could it be that RAS-CAS shi-t?
