I've always been partial to Kingston, Corsair, and Crucial.  There are alot of different brands out there that you could get though.  In the case that your talking about I would look at quality since you will be putting more frequent strain on them.

What ever you look at pay attention to the voltage requirements of the sticks. The 720 mb is a bit finicky with the voltage levels when populating all four slots. Try to keep the mem voltage to less than 2.2v if you want it to run at the highest spd.

 I am very partial to OCZ memory mainly due the outstanding tech support they supply if needed. They are second to none in the tech area. 

 

This will work well

as will this

Only thing to watch out for with the OCZ memory is some of the reaper versions are so big, you cannot physically fit them into the slots, you would only be able to fit 2 x 2gb modules, not 4 x 2gb modules. As I found out!

So, am I reading that second link correctly? If so, for about 132 bucks (before shipping and after rebates) I can get 8G of 800 MHz ram running at 1.8V???

 

If so, I have 2 questions: Can I effectively run it without issues at the EP setting currently in my 720's bios for 1066 MHz? Will it fit uner the Corsair Dominator fan set? (if not, is there an active cooling solution for this memory that will fit a 720 H2C?) 

 

Before I get all excited and order it, is there any issue with Vista Home Premium 64-bit, Dell 720 H2C, and 8G (4x2G) of this memory running at 1066 MHz all working together happily? I'm sorely disappointed that the Corsair Dominator sticks I bought do not function in my rig when OC'd to 1066 due to the voltage requirements.

neither of the two i linked are EPP certified. they will only run at 800

I have 4 1 gig stick in my rig and i don't think the 2's are any wider. gdwrnch3 has his filled with the 2 gigs. It is a bit close but not that tight

For what it's worth, I have 2GB's of the Corsair Dominator RAM in a 720 with a Quad Core and they runn at 1066 no problem.

 

Evil.

OCZ ReaperX edition indeed's too big with their heatsinks for 4 slots...

 

but Reaper HPC edition'll sit side by side flawlessly with 8GB/4GB(4x2048 or 4x1024)...

Different/same systems,different setting/hardware would result different outcome...

 

OCZ Reaper PC6400 version's EPP-Ready@ ,enable it through Bios,it'll be 4-4-4-15 2T 2.1V @800MHz in CL4 edition & 5-5-5-15 1.8V @800MHz in the other edition (default)

 

disable EPP/SLI from bios and tweak it yourself with memset v3.5 or ntune v6.02,it can OC to 1066MHz(the most) I'm running at 1048MHz right now

 

Overclocking it's pretty easy with those memory sticks but have to test it step by step(voltage,tREC,tREF, tRAS...SPP voltage,etc) to avoids BSOD or other errors...

 

if you hate to OC,just simply buy the PC8500 with 1066MHz bulit-in...but not many rooms for OC cause the Dell 680i SLI Mobo'll not gonna to respond it well...

 

JMHO~~~Peace~
