hi,
new rive owner here. i have the following.
ASUS S2011 Rampage IV Extreme Motherboard with BF3
Intel S2011 Core i7 3960X 3.30GHz 6x Core EXtreme CPU
Corsair Hydro Series H100 CPU Cooler
NVIDIA GTX570 OC 1280Mb Gigabyte PCIe Video Card
Silverstone 1200W 80Plus Gold 135mm silent fan
240GB OCZ RevoDrive 3 X2 PCI-Express SSD
NVIDIA GTX570 OC 1280Mb Gigabyte PCIe Video Card
This is a brand new system that I built today and I am having trouble with DRAM. The system isn't posting and I have the red DRAM light on. Have tried all sorts of combinations of ram and just 1 stick, tried mem ok thing as well.
Any ideas on the G.Skill ram that I have. Could the motherboard need a bios update? I am considering going to buy some other brand ram just 4gb to see if it will post.
Help would be appreciated, some nice rigs you guys have here, Will need to try some over clocking at some stage.
Thanks
What Gskill ram do you have? Have you updated the bios? Running on Optmised defaults ?
5.1Ghz stabil so far.

Will work later on to get the voltage down.
1.530 volt.
Not sure about this "bclk sweet spot" theory. What do you asus guys have to say about that?
not sure if it makes such a big diff in vcore required but i think it holds a lil bit of water and thats why the bclk skew / pcie skew is there becos i think changing skews changes the sweetspots.
If I don't increase PCH voltage, I can't clock my cards past 800/4008 no matter how much voltage the cards get (3GB 580s).
Increasing PCH voltage to 1.25 will take the cards to 900/4200, has anyone else experienced this?
Assuming there are no major differences in memory frequency, it is entirely possible that asking the internal PLL for a greater level of multiplication of the reference clock produces more phase error or increases jitter. If that were to be the case, increasing Vcore and tuning the voltage of any other related bus becomes necessary to counter any loss in sampling margin (may not always be successful either).
Are you using the red memory slots? I have the same kit, they work great on this board.
hi guys, thanks for the responses.
i am filling the slots as per manual for 4 sticks.. they are the gray/black ones from memory. i tried ln2, no go.
i am going to try some other ram this evening them update the bios to see and also maybe try red slots? very disappointing last night to not get it going :(
please try this bios to see if you get back your OC

I just picked one of these up along with a 3960X (3133B429). Just waiting for my new loop to get here and get the build going. First EE...hope its fun.
Very interesting, tested and confirmed this myself and for this CPU Im finding bclk 130-133 to be optimal. For example, dropping to 100.00 x 50 requires 0.045v more on vcore for stability than 131.6 x 38.
Are all CPUs going to be totally different for optimal bclk or is a 130-133 range going to be optimal for several CPUs? I would try for myself but I only have 1 CPU here right now.
I just noticed that my board basically doesn't POST with Offset Vcore and a different CPU strap. It just sits there powered on, fans running, with error code 79. Only the standard 100MHz strap works. For alternative straps I need to use the stationary Vcore method. Is this a bug/defect? Thanks.
