I am planning on upgrading my system to Vista 64 so that i will actually detect 4 gigs or more ram properly. Now at the moment i have a lot of ram but it is pretty much the slowest DDR2 i can get and its set up in a messy manner because when i built it this is what i had lying around, a 2 gig stick and 2 1 gig sticks.
Now what i am planning on getting is this. My mobo says it supports 1066 so i want to do a matched pair of 2 gigs for my vista 64 once i pick it up. I want to know will this really be worth it? Also does vista 64 detect 8 gigs of ram? Do i have the possibility of putting 2 matched pairs of 2 gigs in there and have it function or should i not bother?
Also i am using an SLI ready 600watt PSU but i cannot remember the manufacturer, its all shinny and silver though and its been really good to me so far.
As for the processor its a AMD Phenom x4 9750 AM2+
Actually a 64 bit OS should be able to use up to 16 exabytes of memory. Unfortunately CPUs generally artificially cap the amount of memory that can be used but even with this limit the amount is way way beyond what any desktop will use.
Personally I would only go for 4 gigs. The system I'm using now running 32 bit barely ever uses all of the 2 gigs I have.(Crysis got it up to 97% used) 8 is way overkill.
It appears the AM2+ CPUs do not support more than one 1066 stick per channel, meaning you can't run them dual channel. Pretty awesome limitation if you ask me.
Thats messed up, on the mobo box it says dual channel and 1066 for AM2+ only. So maybe it will be better to go for DDR2800 and dual channel it? Or would non dual channel 1066 still outperform it?
another interesting factoid: "When you use DDRII 1066 memory modules on P5QC, only maximum of two pieces are supported. In addition, please insert the memory modules into the black slots (A2/B2) for DDRII 1066 support. If you use more than 2 memory modules or insert the memory modules into the yellow slots, the maximum memory frequency will be limited to 800MHz."
So it seems like if i want to go 8 gigs DDR2800 is probably the better way to go.
Indeed - the only thing 1066 does for you is give you better headroom to OC your RAM.
Are there any desktop level boards that currently support 16 Gigs? I'm guessing I'd have to find 4Gig DIMMS somewhere, but do current boards / chipsets support this configuration?
everything else will only support 8 gigs
This is the second thread you've put that bullshit into. Most boards on the Intel P45 chipset do 16 gigs just fine. That is, if you can find 4G sticks for them, which are a bit pricey right now.
