i tried running the ram at 2000 with 4000 uncore. first i tried 1.45 qpi/vtt. wouldn't load windows, tried up to 1.57 i could get into windows load up hwmoniter and linx. and it seemed stable at 1.57 qpi/vtt.

My question is . having almost 1.6 qpi should i consider purchasing a ud7 with a water pump i mean my temps arrant really that bad even with the 1.45 intel qpivtt spec. the north bridge gets to 60c max at 4000 uncore and 2000 ram.

Is there any voltage IE, IOH or QPI PLL I can you to stabilize with lower qpi volt?

If you've truly found stability with 1.57v, then great. Also, it is not the northbridge that deals with the ram speed anymore. The qpi/VTT deals with the IMC (integrated memory controller) and the qpi (quick path interface) on the CPU itself.

You might try a few things to lower the qpi/VTT:
1.) Raising the PCIe Freq to 102. It not only allows you to reach higher baseclocks but also to use less qpi/VTT at the same baseclock. However this is not guaranteed and you may find that it destabilizes the overclock.
2.) Increase qpi pll and try lowering the qpi/VTT. May or may not work.

There are no guarantees to get it lower.

so the temps of the vtt/qpi are on the cpu its self?. i will have to try the 102 pci-e and lower qpi..
so my question is if it worth getting at ud7 or ud9 , running water though it so i can stay at 1.55 qpivtt 24/7 ?

No the Qpi/VTT would generate heat on the CPU not NB, your NB is getting hot because you are OCing and the QPI is being boosted and the NB has to keep up thus you raise IOH core. The IMC actualyl provide a hefty portion of the RAM voltage. The reason you are having trouble is because of your ram speed, most people do not run 2000mhz ram unless they are benching. !.5-1.6qpi/vtt is dangerous, but its acceptable in these circles, its dangerous because you are shortening the life of your IMC from 10 years to like 3-5 years just from heat and electron migration. Try the qpi pll boost you have one of the only boards that has qpi pll, ASUS boards do not.

it is only worth it to get a UD9 as the UD9 has a binned IOH for 220+ no slow mode. Your CPU wont go far enough to need it under water. just put a fan on the IOH you will be fine.

hah well i took off the gigabyte litte pos metal peice on the NB and installed a 90mm fan attached to my corsair memory cooler blowing on it. i will get some pics up... Works Awesome!!! as idling at 45-47c before now idle at 38-39c and load at 44-45 thats the NB temp... I am also set at 1600mhz with timings of 77720, Question, could i try to fun lower timings like 6,6,6,20, i have corsair 2133 dominater gt;'s at cas 9. and im running cas 7 at 1600,
My question is do i have to UP the QPI VTT volts in order to run the ram at a lower timing because it technically ocing it, "the imc". thanks for the support.

BTW i also put the ram at 1600mhz with uncore at 3200 and it was fine, my i put my ram timing down to 7,7,7,20 also.

AND!!!! i tried the new f7g bios from the x58a-ud3r rev 1 motherboard and it seems to run more stable then the f6 bios. even tho its beta. thank yo

yea, wow. My lame chip wont even break 4.0 without going over 1.3875 and then I get temps in the mid 80's, but then Im using a cheap cooler master hyper 212 with only on fan on it =]. The 950 seems to want a lot of volts on the upper end clocks. Ive got my QPI/VTT at 1.38 also just to stay stable at 1600. fro 2000+ you'll need to get up there.... further than you want to go.


Good luck.

I hadn't heard the PCI-e bit yet. I may give that a go and see if I can drop a bit off my QPI/VTT. My chip isnt the greatest clocker so an little bit would help.
