AMD Phenom II TWKR Black Edition Processor

0 thumbs up

In our review of the Phenom II X4 955 processor, we were able to reach 3.72GHz at 1.5V using the stock cooler. Additionally, we saw idle temps of 35'C and load temps around 70'C. This time around, we used dry ice to cool the TWKR chip way down and cranked up the voltages not only to the CPU, but other system components as well.

For the results you'll see below, we used an SB/HT Voltage of 1.3V, a CPU PLL Voltage of 2.5V, a NB Voltage of 1.2V, a CPU NB VID of +0.300 and a CPU Voltage of 1.55V

Overclocking The Phenom II X4 TWKR

AMD Phenom II X4 TWKR Black Edition Overclocked to 4.73GHz

First, we would like to note that we tested the TWKR with a watercooling solution to find a good starting point for our dry ice benching. Using CoolIT's Boreas TEC Chiller, we managed to hit 4GHz with no issues. That's all we could get from the chip with this type of cooling, even though the load temps topped out at only 32'C. 

Then we installed the Koolance LN2 pot and after several overclocking sessions and about 20lbs of dry ice, settled in at a 4.73GHz overclock. At this speed, we were able to conduct several benchmarks in order to measure the performance gains created by such a large overclock. While the bandwidth numbers shown above are very good, we feel the 3DMark scores aren't anything to sneeze at either.

Under dry ice, the TWKR produced admirable results, but we weren't able to achieve the kind of overclocks these chips are known for. Even our watercooling overclock was surprisingly average. So what gives? The main culprit is cooling, according to AMD. For the TWKR to reach its fullest potential, liquid nitrogen or liquid helium must be used. Doing so would allow for a much higher overclock, "dropping (cooler base) temps from -70C to -188C makes a huge difference in terms of TWKR clockspeeds. You would likely get another GHz or more extra speed with LN2" we were told. The lesson here is to not skimp on the cooling when it comes to the TWKR. Once we get a hold of some liquid nitrogen or helium, we will post some more results and update this article. For now, here's a glimpse of what some others were able to achieve.

Thats some sexy overclocking.

That clear pot in the video is kick ass too.

 * Crisis Causer wants.  Just pushing it as far as I can on air would be more than satisfying.

It's pretty cool that HH gets to test one of these even though there are only around 100 in existence Big Smile

Yeah good job on getting hold of one of those!

The clear pot is pretty cool (lol), but the music in the video is a bit silly... I mean, c'mon, it's not life or death!

     I attempted to get in touch with AMD on one of these. I was able to talk to someone, however; it seems that being a long time supporter of AMD, whose desktop's both still run there processor's, and who has used them for years as well as built several systems for family members and paying customers using there technology is not high enough on there register of importance. They basically would not even give me any information at all other than it does exist which I already knew.

Yeah. I dont think any of us are going to get are hands on one. I think they want people that will generate press with them.

Well BOB that would be all of us here at HH would,nt it! Amd needs to give us all one and Im sure we,ll all makes some noise for the press!LOL I know I would be all over U Tube and be post my 3D Mark scores all over the place!LOL Now if Raid shows up with one then we know he,s got money! HA HA LOL and then I would be jealous!Zip it!

     Yeah, it seems Loyalty or good customers in general mean nothing to AMD. Lol anyone (especially someone who posts daily on tech forums) like us would generate good press for AMD. I use X2 processors on my desktops now, and have built many systems for friend's, family and paying customers using an AMD platform. I always saw them as a great cost performance avenue. You hear a lot of people talk about the I7 cpu platforms; and to tell you the truth price wise there is only a 1-200.00 dollar difference price wise now. Seeing as loyalty means nothing maybe I will go Intel on my next build, as supporting a company (as I have for years with AMD) means nothing to them. So why should it mean anything to me as a consumer???

Maybe we can get Marco and Dave to get AMD to send us all one they got the Pull around here! Then we will have the Longest Thread forum reveiw ever put the chip through the ringer and then all of us can post it on HH and U-Tube and then they will get there advertizing and promote the new chips for them and save all that cash on advertizing! Sounds good to me!!

lol. I wouldn't mind throwing one of those under my water loop and see if I can bet that 4GHz in the review.
