What clock is your rig running at? and maybe bump the dram voltage up to 1.65volts cause when i run my rig at 5Ghz my ram is at 2050mhz thumb.gif

this is 2133 so i was trying to run it a 4.750 so 37 multiplier, 125 strap, i was trying to use the 2000 strap for ram in the bios......my mushkin 1600 i have ran this clock at 1666?

If chip has a good memory controller it could handle that speed but sometimes they simply dont like it, especially at high clocks. I am sure if you lower your clock a bit and increase the volts on memory, they will reach 2133.

i thought the ram should just run at the speed it is supposed to

If cpu is overclocked IMC might have a hard time to keep up with the extra ram speed.

well i have only tried 1.6v on the ram cause that is what the xmp profile called for....i will try some more voltage

So if this CPU is not unlocked how do you overclock it, can you just change the multiplier X43 for example or what?

And I will only ever buy asus rog boards cause you get what you pay for, apart from my sr2 smile.gif

did you forget about the 3930K? it is the 3960X with 3MB less L3 and about $550. Seriously x79 is such a waste on a 3820.

Not if you use the RAM Bandwidth or extra PCIe lanes but don't need 6 core performance, or if you plan to go to IB-e but want to buy stuff for it now, X79 with an i7 3820 is going to be way better if you have two GPUs and a RAID card for example, I want to go X79 and a 3820 because the extra $100 I put down on a motherboard (Really, it's the nearly the same if I was comparing it to the equal Z77 board, both UP4s) is worth having the benefits of X79 as well as being able to get an IB-e 6 or maybe even 8 core later.

Change multiplier and BCLK

I don't see how its a waste to put a 3820 on a 79 platform, future upgrades and I see alot of gamers going for it aswell.
