Wow that's a trip, the range within the batch. Same was true with 820a599.

Anyone receive an 822 in the US?

**~~emoners~~** · 10-05-2008, 10:36 PM

so the good batches are in the 820s-822s?

I don't undestand witch setting it is.
There is no fsb ref setting in my p5q deluxe bios, what is the model of your motherboard please ?

As always it's hard to say, hit or miss even within a certain batch.

I haven't been tuned in on buying one since summer, but last I checked most in US were getting 820 and in EU 822. Can't remember hearing of any other e86 batch.

Some 820's are not so good.

Yes, very nice.

Mine is Q820A670. 1.2500 VID.

There's a Q821 batch also, as far as I know.

Here is my humble contribution to this thread:

Vcore can probably be a tad lower, set it to 1.296 to be safe, i don't want to go through another boring few hours of prime

Setup:

E8600 Q822A435, vid 1.1750 - Rampage Extreme- watercooling.

3+ hours of Prime small FFT's cause small puts the most strain on the CPU.

humble!! yeah

Bravo Zeus, this chip is really making it crazy

Yeah, it's a nice CPU, it can run 4GHz undervolted to a whopping 1.12V

and 4.3GHz with just 1.204V -- Orthos small ffts stable that is. 20ºC+ ambient.

**flesheatinvirus** · 10-06-2008, 02:04 PM

Nice chip Zeus.

**JohnnyV** · 10-06-2008, 09:24 PM

Yeah awesome voltage for those speeds. Can you share your other settings with us?
I'm curious whether settings like CPU PLL and vTT contribute to this.

Here you go

**Pisklink** · 10-07-2008, 12:25 AM

Damn dude, those are really low values compared to what I use. I think that REX is a really nice board and it's awesome that it employs so many sensors.

These are my bios settings for 4.4Ghz (464 x 9.5) Prime stable settings:
- vCore 1.4125v (gives 1.344v under load in CPU-z)
- CPU PLL 1.58v
- VTT 1.26v
- vNB 1.55v

**Dee** · 10-07-2008, 04:47 AM

Zeus -- great results there bud! Very nice chip.

CandyMan -- you're doing fine. Considering my E8600 needs 1.4v for 4.33GHz I'd say your little E8400 is better than my chip. Make sure you have the latest Core Temp to see accurate temps.

**Zeus** · 10-07-2008, 08:47 AM

Just had to try at even lower voltage, merely for bragging rights.

1.288V stable as a rock, i won't discourage you guys by saying even lower could be possible but i have a gut feeling....

**Dee** · 10-07-2008, 09:43 AM

Very nice. Mine will probably do around 4.10GHz max with 1.288v.

**DemonEyez** · 10-07-2008, 10:55 AM

sorry for the double post

Man, you're one lucky b....

I need this for my Q822A435 VID 1.2000

Still testing if it can withstand 4 hours of Orthos, rightnow it's priming for 2.5 hours so no complaints

(finally got it stable after flashing older bios for my P45 T2RS Plus and tweaking GTL on second core)

**Zeus** · 10-07-2008, 11:43 AM

DemonEyez, your sig says 9x600 @ 1.37V, that's an awesome CPU mate, wanna trade?

whoops, should be 9x500 @ 1.34v

**JAPANAC** · 10-07-2008, 03:20 PM

E8600 @ 4.5GHz (IFX-14, 2xTT SilentCat, ~23C ambient)
FPO#: Q820A600 (Pack Date: 07/29/08)
VID 1.25V
Vcore 1.392 load (450x10)
Vcore 1.408 load (500x9)

Where is BeastNotro these days? I rarely see him anymore.
