Ivy or complete change to skt 2011?

[eyetrip]

what happened.? why gigabyte is a rubbish board?

Awful, awful BIOS.

Difficult to get even mild OC stable.

Does not like 125 bclk for 3820

Does not like high memory speeds.

Other stuff, but will leave it at that. Just the worst POS mobo I used in years.

Got my Rampage IV Formula installed last night, and man what a difference!

This thing just oozes quality. Most expensive mobo have ever bought, but I don't think I am going to regret it.

Looks the business, feel solid and heavy, and the BIOS is just a thing of beauty.

Only small niggle - thought I was getting the BF3 edition, but got standard one But that's not the the boards/Asus fault

You just cannot beat ASUS mobo's, and I would never buy anything else. Every one i've had has been brilliant.

Seriously contemplating just going 3930K now maybe not even bothering Ivy-E

Not that the 3820 is bad, but I was hoping for 5GHz, but I just can't get there.

With 3930K would be happy with 4.5 - 4.7....

Agree on the whole Asus motherboards being ace, massive fan here.

I'm glad i'm not the only one that chose x79 can't wait to get mine this weekend. Would be nice to get 4.6~4.8GHz out of the 3930K

Hmmm, as a 24/7? As a rough guide with an H80, at 4.2 and 1.215v no LLC, IBT pushes mine from 30C to the mid 60s. 4.4, 1.28v and 25% LLC, it goes from 35C to max 70C. I find the H80 fans a bit loud under load, so I'm at 4.2 until I replace them. However, even at 4.2 (with HT), Cinebench reads around 12.2 (was 12.76 at 4.4). As Sandy/Ivy scores 7 to (absolute) 10, you get a rough idea of an HT performance comparison. After my fan swap, maybe I'll try for 4.6 and 13 in Cinebench

I'll be using a Phanteks PH-TC14PE and staying under 80~85c in IBT is my target so i should be good for 4.6GHz+

Well, I went ahead and did it. 3930K ordered.

Just felt silly having top motherboard, etc, and having an average chip....

 

[stone_cold_Jimi]

Well, I had a play. 37x125 so 4625 at 1.340v and LLC auto, failed IBT after a couple of cycles at very high but scored 13.46 in Cinebench. 46x100 at 1.335v same outcome with IBT. Top core temp was 75C. I've read somewhere that temps should be 20C lower than TjMAX (91C) so 71C seems to be the advisable max.

It's tantalisingly in reach, but perhaps 4.5 is a more realistic stable clock.

Edit: As predicted, HT on, all power saving modes on-

36x125 4500
1.325v BIOS, 1.344v CPU-Z max
Idle temps: 37-30-31-33-33-33
Load temps: 76-71-66-66-69-73
IBT Very High, 10 cycles
Cinebench 13.04

Corsair H80 on medium, Mobo is P9X79 Pro, RAM GSkill 4x4GB 1600 @ 1666 (@Just under 1.5v). System Win 7 Pro 64-bit.

I'll keep this for a while, might be my 24/7.
