Phenom II Black Edition TWKR 42 Unveiled

NDA has been lifted off AMD's newest processor for serious overclocking, the Phenom II Black Edition TWKR 42. While this processor isn't meant to be an out of the box high-speed performer, it caters specifically to those who know (TWK) the inside outs of overclocking. Hence, it comes with a speed of 2.00 GHz, but with an unlocked multiplier, high-leakage silicon, and a significantly higher overclocking headroom compared to other consumer-grade chips AMD offers. Currently AMD has only 100 of these ready to sell.

Legit Reviews is one of the first sites to review this chip, and adds an interesting list of myth busters to go with it. The chip is based on a cherry-picked high quality yield of Deneb C2 core. It comes with a vCore value of 1.44 V out of the box, and lets the overclocker decide which bus-multiplier, frequency, and voltage value to use. It comes in an exclusive jewel-case from AMD. Using air-cooling by an XIGMATEK HDT-S1283, the reviewer was able to reach 4.00 GHz on the air and more than 5.90 GHz using liquid-nitrogen cooling.

Well then you better update wiki http://en.wikipedia.org/wiki/Leakage

^^

Can you explain or point to what you mean by leakage?
I'm completely at a loss in what is good spec for OC'ing the latest AMD cores.
there you go

OCC
What can be gleaned from this is that the TWKR Edition is a high leakage part, which means it has a higher static current, drain to drain. This makes it an excellent processor for overclocking since it can sustain very high voltages when combined with the excellent scaling of the architecture at very low temperatures that we have seen since the X4 940. So now, let's see what we can get out of that TWKR.

I am not verry impressed. 4Ghz on air does not sound extraordinary.

I have an old rig with a new CPU and graphics card. I have a DFI 790FXM2RS (withSB-600) motherboard, OCZ 2x1gig ATI crossfire edition ddr2-800 memory.My CPU is 940BE with an old Scythe Ninja2 air cooler and my graphics card is an ASUS EAH4870DK 1gig edition.

I am NOT a professionnal overclocker andI manage toget a verry stable 3,7Ghz at 1,4Vcore and 2,2Volts on my memorie (OCZ recommended setting at 4-4-4-15)

I really incist on the fact that I have mostly no idea of what I am doing when OCing and that I OC using AMD overdrive.

I have juste run 2 batchs of test with everest (onestock, one OCed, to proove I am not lying), I wanted to upload them, but I am not sure how to do this with my pictures onmy HDD and not on an URL

I have to agree since AMD has said that we would be getting 4ghz CPU's out of their Phenom II's before they were released.

while i agree with the point 3.7ghz is a super average oc on a 940BE

Thanks, just a little confused. Uses more Volts but puts out less heat?
Never the less I get the idea that using more volts is better since it's easier to regulate 2v than 0.5v.
pretty much also the chips are still stable with more volts

If intel did handpicking it would do 5 GHz on air.

Problem is a core i7 920 (some new revision i saw on anand or xbit) reaches 4ghz on air and kills the phenom 2 in almost any game/application , end of story.
Enthusiast stuff doesn't matter for the majority who wants to play tetris , or wants to encode some porn for his iphone.
My thoughts to AMD , your current generation of cpu's SUCKS compared to the competition(considering overclock ).

example for the "el-cheapo" Pentium Dual-Cores
those chips can do 4 on air with a leetle bit of tweak in the VCore

my E7400 runs @3.15 @ 35C stock cooling...

I am aware of my average OC, my point was exactly this, if an amateur like me, not knowing exactly wath he is doing, can easily get 3,71Ghz out of a standard 940BE with an old and not so good cooler, those TWKR edition OCed by professionnals SHOULD get better than 4Ghz on air

Don't see why -- the TWKR chips are apparently meant for LN2 cooling, since they're picked to be used at extremely low temperatures. Doesn't necessarily mean they're going to do any better on just air. ;)

These editions are for people with at least water-cooling - the reason that they are high leakage is so you can pump volts through them that would murder a retail part. This chip is a toy, that's it. It's designed for people who like to play with chips.

found out what the issue was gomeler had a bum core that explains the lack of OC only 6.58ghz outta him lol

In all the hustle and bustle of K|ngp|n and Shamino's Vantage bonanza we nearly forgot about the AMD AM3 parts that were hauled to the event. After a midnight dinner we prepared the Gigabyte 790FXT-UD5P for a quick and dirty run with the last 7 liters of LN2 of the night.

Gautam prepared/battled with the OS that had been on a Classified, Rampage II Extreme, and then the Gigabyte 790FXT-UD5P, I prepared the insulation, and Vapor had the magic touch.



First a little 3D06, it has a bum core holding it back.



All 4 cores :shrug:

And then the real fun began with commentary as close as possible to what occurred.

Me: Eric, can you hold the board, I need to twist off the pot.
Eric: Pulling the pot off at -192 Celsius?
Me: Yeah, I do it all the time.

*crack*



Shamino is examining the destroyed socket, not sure if he can solder and hot-glue it back together.



Look at that insulation job, zero condensation between the board and the eraser. 3oh6 would be proud :p:





I do believe this is an AMD world record, first motherboard socket ripped in half at -192C.



Turns out I did it 1 too many times :D

Huge props to everyone for everything, was a great weekend :up: Now to see if I can RMA this board :cool:

Erm, he's going to RMA a board because it broke at -192C?
I don't think thats an inherent fault lol. *goes a stress tests plastic for fun*

What a waste of a good mobo...

And these "TWKR" processors are hardly anything amazing when the world record OC on a Phenom II was reached with a "standard" X4 955 BE:

Once again, another marketing ploy from AMD... they seem to be getting deperate, I hope for their sake that Intel doesn't decide to release cherry-picked CPUs!

Well, this prooves how little I know about overclocking, thank you guys for putting things straighter in my mind.

It's with forums like this one and a little curiosity that people like me can begin to understand and put more interest in things like overclocking.

Calm yourself man geez no need to get your panties in a bunch :laugh:. I am sure if cdawall had his hands on that CPU it would've been way higher than that guy from legit reviews... AMD has no reason to be desperate right now.

the twkr chip is 300mhz higher than the next highest legit score

Its to mess around and clock it at whatever you want. Maybe it is an excuse for it to be somewhat cheap :rockout:
