In line for an upgrade for what? Anyway i think im going to stay at 3.83 until i can get a new CPU cooler, Powersupply and get a new SPP fan. I found a good thread over at http://www.evga.com/forums The NB is exactly 60x60 so i can fit a nice fast 60mm fan on that b aby

In line for an upgrade for what?

A new 780i board.
My 680i died from a C1 error 2 days prior to 780i promo expiring. I didn't want to leave the promo for an RMA.
So i went out and bought one, then when i get the new one, I'm going to sell it!

And yes I talk to Mike @ EVGa about me turning in a bad 680i and he said not to worry about it. They will take it (no charges to me other then the upgrade fee)

haha its not linked anymore, im running at 1700 QDR with 1066 on the RAM 5-5-5-15

Guys, what does it mean if im getting lock ups in the bios. All i did was set the FSB to 1780 and linked / synced the ram. I have all voltages on Auto except my CPU and Memory. CPU is at 1.375 which gives me 1.32 under load in windows. Uhmmm thats it, not sure what else to do. besides get a new powersupply, which i think is the culprit. Any suggestions?

I would get a new power supply...

Do yourself a favor and unlink the ram. Set the ram to Expert in the timings section and leave everthing to auto there. By linking the ram your are throwing in way to many error factors. The proper way to overclock is to do things 1 by 1. Dont try to get it all in one shot.

What do you mean.... leave everything in auto??? Are you talking about TRAS, TRC, TRAD, TRP, TCL????

I dont think we can be sure that the PSU is a problem without actually testing it. I am sure that 650watts is plenty.

Yes leave all the ram timings at default. You have to take this one component at a time. If the ram is set to unlinked, running stock speed,and stock timings, then you will be only working on your cpu speed. When ya get you cpu max then you should start working on your ram. Then move on to your video cards. One component at a time.

Whats your VCore for 3.9? If you're failing in 30 min then you just might need a bit more vcore. Whats your cooling solution?

When i got to 4.5mhz i was running -
1.56 vcore
1.5 cpufsb
1.5 spp
1.65 mcp
1.4 spp<>mpp

How did you get 1.5 on the CPU FSB. I am limited to 1.4v in my bios. Im using the Zalman 9700LED. Im getting the Thermalright IFX-14 soon, and 2 140mm Yate Loons or something equivalent. My ram is 100&#37; stable at 1066 5-5-5-15 but i know what your saying.

Ok well im trying 1780 QDR (4005MHz) at 800 and 5-5-5-15, which is way below this G.skill 2x2 set, this set runs at 1000MHz, but i said screw it for now.

I copied your exact settings besides CPU FSB and Vcore, because 1.56 is way crazy on Vcore and 1.5v on the CPU FSB i cant get that, mine is topped at 1.4v. It failed within 2minutes at those settings. So i dropped the SPP a bit and took my Vcore to 1.425 (1.36 on load) and its at 7minutes so far with no problems. my question is, Why is everyone achieving such high SPP voltages when mine gets way better times and stability with auto or really low voltages? Do i have a magic board or a bad one? Why is everyone getting 1.5v on the CPU FSB and im topped at 1.4? Oh the questions

Edit -- 1 Hour and 45min OCCT and Prime95 so far, Gonna let it go till this movie im watching ends then i'll let it go overnight once im done playing. but i got 4005 at 1780QDR. I cant believe it. Woo!!!

Same exact scenario happened to me over the weekend. LOL!
