what are you cooling that with?? a hair dryer?? lol
mine is close to the same speed as you but, damn your temps!.

MoRa II pro!
Heatkiller 3.0 LT!
HPPS plus...
Your temps look really nice, but is that stable! Let the workers run! Don't stop it!

[roller11]

okay well here is a link to 5.0ghz stable using your methodology

No validation, no 5.0 Ghz.

What word would you like us to use then?

As I said, use anything you want as long as the computer is functioning properly. That's the definition of stable.

justin-nice set-up, what are you using for cooling ?

[emertX]

I think he has a chiller!

It's a validation, what about it?

justin-nice set-up, what are you using for cooling ?

yes it is stable. I have bumped it up to 4.6Ghz now, here is 50 passes of Linx got a bit hot though..




water cooled, heat killer, 2 tripple rads, 355 pump, with Xspc top. cool room 19C-20C ambient temp.

^ amazing work man

[ReverendMaynard]

Awesome justin!

[raptord]

first boot up, no stress test yet. D0 3849A859



I really need get a better cooling, water maybe????

[justin.kerr]

^ amazing work man

Awesome justin!

THANKS! Its been a real fun project so far.

[Utnorris]

Nice job guys, some really nice overclocks.

[roller11]

Utnorris,

At what Vcore did you achieve your 4621 validation, and was that with H2O cooling?

I also wanted to know this.

[roller11]

raptord,

Is your CPU maxed out at 4532? By that, I mean did adding more Vcore help get more CPU clock?

raptord,

I don't know, the room temp is like 27-30 degree and I am using Noctua NH-U12P. I can't put more Voltage ATM as the idle temp is in middle 50 and I saw 70 sometimes even not under load.

[raptord]

It seems I really need better cooling than NH-U12P, but air cooling is my only option here. Anybody has suggestion on a better air cooling solution?

Time to lap that badboy. And yes, I'm serious. Cut 5-8C off of my load.

Those temps sound higher than normal. Does EIST work on your board? If so, enabling EIST will bring those temps way down.

By far the best air cooler is the ifx-14 by thermalright. review sites put it ahead of True, the latest scythe, 120 extreme.....it's the best there is today, period. The best part is that it can hold two fans because it is split, so one fan can go in the center with another on the outside in the conventional location. But even with just one fan it beats all other coolers by a wide margin, so on a "same fan, same fan speed" compare, it beats all comers. See the review on mad shrimps and other sites. It;s designed for either 120mm or 140mm fans. Only possible problem is because it's extra wide, it will hang over the side of the mobo on the EVGA and DFI mobos because they put the CPU socket near the board edge. On all other boards it will be fully over the board.

Well EIST is complicated here. I use the V1 1403 BIOS on V2. Most of the time with HT off and Bclck>=200, the multiplier stays at 21x (which is set manually in BIOS). But I do see a flash of 12x multiplier when cpu is idle. But that 12x is very short, like less than .5 second.

[Utnorris]

Utnorris,

At what Vcore did you achieve your 4621 validation, and was that with H2O cooling?

That was at 1.39v vcore and 1.41v vtt/uncore. I was able to run PI under 9 seconds even though my ram was only at 1333Mhz, however it was not stable. Without being able to adjust the PCIe frequency I may not be able to get it stable at anything over 200 I am afraid.

[rge]

yes it is stable. I have bumped it up to 4.6Ghz now, here is 50 passes of Linx got a bit hot though..

4.6ghz with 1.392v making it through 50 passes of linx 64bit using 5gb ram is impressively stable! Sweet overclock! And your temps arent that bad for that OC,voltage, and using linx 64bit.

[ghost_recon88]

All you guys hitting 4.4-4.5GHz 8 thread stable, what QPI and other voltages are you using? Just wanna get an idea what the rough average is.

[justin.kerr]

Qpi 1.3v
PLL 1.8
Don't know what other voltages you want listed?

IOC & IOH voltages as well maybe?
