Started upgrading an HP pavilion, a few issues

After doing alot of reading on this,and similar sites, ive learned that my BIOS is pretty much bare. It's a ECS nettle2 MB driver version 5.19. I need more ram to make hellgate run a little smoother and after reading several complaints of low latency ram reverting to default timings of 5-5-5-15, I'm wondering would there be any reason to buy ram with 3-3-3-10 or 4-4-4-12 timings? Does all ram change,and need to be set manually? Is there any way to get a new BIOS? Thanks in advance for any help you can give. 2.9ghz brisbane dual core, 2gb 667mhz samsung ram, 8800gt gfx card, 550watt ocz psu, POS ECS nettle2 MB

Heh, the 667mhz version of that ram was what i was looking to buy http://www.newegg.com/Product/Prod [...] 6820146093 . Chipset: mcp61 rev.2 Is there anyway to switch the timings to what i want other than through the bios? And im staring at cpuz as we type, Freaking cool as hell.

The ram from my previous post says voltage 2.1-2.3 in its specifications...would it for any reason go to 1.8v?

Yes, the voltage for DDR2 is 1.8v period. Your computer is an OEM with an OEM motherboard which is designed to last, not be cutting edge. Regardless of what Newegg tells you every stick of DDR2 on their site is 1.8v and has JEDEC timings programmed for that voltage. So yes when you put those in they will run at 1.8v and no it won't be at those timings. If your interested in those I would call Mushkin and ask what the timings are at 1.8v, their customer support is very helpful.
