thinking of getting a 780i, few questions though - Page 3

post #21 of 46
I noticed that the various chips were not at the same heights when I took off the stock cooling. I installed a Viper John Kit and substituted the little evercool fan that is meant for the SB with an MCW30. Despite what it looks like three cards will still fit in the slots if you use low profile full coverage blocks like the BlastFlow modular. mn

And the taller heatsinks for the VRMs or whatever those tiny chips are that surround the socket was just as much hit or miss with TIM tape so I used copious amounts of Diamond TIM which works well when thick unlike say Shin Etsu which needs a thin bondline.

If you do switch out the MOSFET/VRM coolers you'll notice that the stock and the Viper John sinks do not coaver all the chips. I think this has to do with Intel Spec for clearance around the socket to accomodate the stock Intel cooler.

I am not sure why the Viper John sink is so narrow since it is obviously for a performance mod...

So if I were to be doing up the 780i for myself with an unlimited time frame and budget I would contact one of our local blocksmiths about getting proper Heatsinks or Waterblocks made that would adequately cool the neglected chips.

Another thing to think about is doing a simple Voltmod to the board to help with the Vdroop. I would set 1.3875 in BIOS when OCing the E6850 which I know to be good for at least 4ghz on an X38 and checked the voltage in HW Monitor in BIOS after reboot and saw 1.33. In WIndows CPUID reports 1.32-1.33 which indicates a base .05 undervoltage even before droop under load. It would drop to 1.29 the minute I started Orthos. I found that I could set the Vcore to 1.5 in BIOS and under load see 1.39-1.42 fluctuating. That's something that needs attention.

so all in all do you guys think this board'd be ok for what i want it for?

i just want my 4gb of pc8000 ram, my 2 500gb drives in raid 0, my 9800gtx, and a decent oc of e8400 to all work rather seemlessly. im kind of a noob if you hadn't noticed and hope that i can figure most of this out by just doin' some readin'.

Spotcool does nothing.

Expect a minimum of 2 RMA's with the board. I highly suggest NOT installing your expensive memory first off as these boards seem to like to eat them for dinner. The North bridge runs VERY hot all the ones I've build have hit 50c idle 65c underload which is VERY hot and most likely why the majority love to trash memory.

EVGA is about to release a FTW edition that has better cooling. You can also buy these coolers for existing boards. From what I've been told 1 is for watercooling the other pelt.

Edit: Go with the 750i if you never plan on tri sli.

will it have any problems with a sata dvd burner? Yes
will it have any problems with vista 64? No
will it have any problems with a raid? No
will it have any problems with an e8400 and oc'ing it? No
will it have any problems with a 9800gtx, and maybe go sli someday? No
how prevalent is the vid corruption thingy? Fixed in last BIOS.
