Watercooling a 790i ultra?

[gurby]

I was planning on buying a EVGA 790i FTW and was wondering what block i will need to cool the motherboard?

I will be getting the EK Water Blocks EK-Mosfet 790i Part 1 and 2

i ordered his NB WB and mosfet heatsinks for the 780i. this guy does amazing work, top quality.
and by motherboard you meant the NB and SB right? or were you talking about the CPU WB?

[gurby]

Ok many thanks will check it out, any other NB/SB blocks?

I have a custom block designed for the 790i Ultra I can post some pictures later. I am not sure if the nb/sb are the same for the ultra and FTW.

No one has asked but is there a reason why you're moving from a good board to a bad board?

You have an Asus Maximus SE and you're going to an nVIDIA powered EVGA 790i FTW. I'm just curious?!

[ElMoIsEviL]

That's a matter of opinion. I have 3 of the EVGA 790 boards, and they're the most solid and easiest boards I've ever worked with. Great OC'rs too. You couldn't pound or beat up a any MB more than I have my 790i Ultra on my bench for testing.

nVIDIA based motherboards have a reputation of losing Operating System installs (corrupting them) when they're overclocked. This is not a matter of opinion but rather a verifiable fact that Anandtech also noticed when testing this particular board as seen here: http://www.anandtech.com/mb/showdoc.aspx?i=3450&p=8

This is why I ask why one would forfeit a far more stable Intel Chipset based platform for an nVIDIA chipset based platform if one doesn't intend to use SLI (his specs show only one card).

[gurby]

Its just that my board dosent support SLI (or does it), I wasnt sure what mobo to go for but i could get FTW kinda cheap from ebay.

Here is a pic of the custom block I have installed on my 790i Ultra

I can say for a fact that my cheapie gigabye p35 can sustain 3520mhz on a 2100mhz b3 quad, while my 780i will not boot anything above 3200mhz. I wouldn't mind 3200mhz plus my 8800gt in sli, but the darn thing crashes everytime forcing me to send it as an Rma.

I'm using my gigabye board as my mainboard, even though it's supposed to be my backup. Intel chipsets are superior. X58 is where it's at.

[century child]

X58 is a brand new chipset, that's why it's superior. You are also talking about 780i while the op is considering 790i. Two very different animals.

I am another person who has had zero problems with my eVGA 790I Ultra. It has been extremely stable from day one and I have never experienced hard drive corruption with it. The only issue I have with it is the location of some of the SATA ports. That's it.

I had my 780I up to 4200mhz with a QX6800. but it would get way to hot on air, so i would keep it at 3.8 for everyday use with 2 8800gt's in sli

[Bei Fei]

My 790 runs my Q6600 @ 3.8 all day no problems.

I had an EVGA 790i Ultra once, possibly the worst board I've ever had for overclocking. Couldnt wait to get rid of it. multiple bios updates never addressed anything. this was the first nForce based board I invested in.

my QX9650 would be stable at a maximum of 3.2ghz, where in an asus p5q deluxe 3.8ghz. both using the same Thermalright Ultra Extreme with push pull fans.
Dont get me wrong, EVGA are great for tech support and their GFX cards are top notch also. but I will always avoid buying their motherboards.. their too new in the game as far as motherboards go and nForce in general is far from perfect.

also nvidia dont really seem to improving this much.. there last set of drivers for the 790i ultra chipset are half a year old, i remember even windows update aparently had a newer set of drivers for my board than nvidia!
another thing that annoyed me is the fan on the northbridge heat pipe system, hands down the loudest fan in my case! never got around to watercooling the board but to have that fan gone would of been worth it.
also used the board with a pair of 8800 ultras when they were stil fairly powerfull, and its put me off SLi for good, if your using tri-sli :eek: good luck! the 9800 GTX was the last card i used with it and that was perfectly stable, in general all the reviews said this was a bullet proof board and for me it was a great dissapointment :(

im very much happier using X58 and even P45 previously, nForce is dead to me :eek:, and ive used nVidia cards since TNT2, shame..!

my :2cents: as far as LGA775 cpus are concerned: X48 FTW not 790 FTW

Oh, that is nothing but rubbish. Those issues were long resolved with later bios releases that specifically addressed those issues.

Suggest you learn to research issues for current data rather than quote obsolete history:down:

I've currently got my qx9650 at 4.28 on my on my striker extreme 2 bios 1202

+1 again, my Q9550 is running just short of 4GHz and I haven't even gotten into fine tweaking yet (I've been overclocking by jumping 133MHz hurdles at a time XD)

[Bei Fei]

I have been running my 790i daily from 4.2 to stock and the only problem I have had is the occasional BSOD, but I think that is because my Q6600 is not 100% stable at high OC's with very low voltage. 4.2 @1.55~1.6V. But I run it daily @~3.8 1.32~1.35 no problems at all. I have also ran my ram @ 1080 8-7-8 2.0v with no problems. But saying all this my 680i gave me no problems at all either. Both versions were A1.

[LeeH]

Look at your NB temp. Mine is still air and it idles at about 59 c. Load pushes it up of course. I will bring it under water this weekend. I suspect that will resolve a couple of issues for me when that and the rest of the board is cooled down.

[0xdeadbeef]

Odd,

I've never lost a OS off any 790i MB and I OC the living hell out of them. As far as Anandtech goes, I don't know what those guys do over there to boards and chips when testing, but I've never had problems with the same stuff they do. They freaked everybody out on the QX9650 a while back too on FSB voltage over 1.30 1.35 v cooking the chips, but the QX9650 I have hasn't degraded one bit. And I've been smacking that thing around since the day it was relesed in the US. TBH, it's not even a good a chip as they tested:shrug:

I agree! I'm running my QX9650 FSB VTT at 1.45v since autumn without degration or any problem. My OC is 4.4GHz rock solid 24/7.
