XSR writer breaks Bulldozer Wprime, Superpi records

Instead of writing my usual reviews, I’m going to take a break and give my new Bulldozer chip a run.

The system I’m going to be using is:

AMD FX-8120 with a Cooler Master Hyper 412S and a Little Devil PC-V2 phase unit.

Gigabyte GA-990FXA-UD7

ASUS Reference 5870

Crucial C300 128GB

Cooler Master Silent Pro 850W

Windows 7 Ultimate x64

Antec SOLO II

 

A few may know of a couple of flaws this board has. First off is the Vdroop. Vdroop is when you apply load to your CPU and the voltage being sent to the CPU drops. The UD7 has this badly and for that reason some of the voltages in the below screenshots are higher than what I would normally use.

The two main benchmarks I focused on are wPrime and Super PI.

First off I checked up on HWBot.org to see what and who I had to beat.

wPrime 7sec 347ms at 4730 MHz on air

wPrime 5sec 991ms at 5587 MHz on Single stage phase

Super PI 17sec 221ms at 5066 MHz on air

There is no Super PI Single stage phase record.

So I dropped on my Cooler Master Hyper 412S with two Gentle Typhoons and opened up my window, fortunately my PC is right next to my window so cold air goes straight in.

Here’s my three scores for air.

Got 1st place with 6.817 for wPrime 32mb on air.

I got 1st place with 17.129 for Super PI 1mb on air.

Finally I got 214.159 for wPrime 1024mb on air, also a 1st.

After those couple of scores I got a bit bored and started setting up my LD PC-V2 phase unit.
Here’s a photo of the unit.

The unit is able to drop -60C in the correct ambient. Here’s a photo of display, this is while the CPU was sitting at idle.

So I set off to beat both wPrime 32m and Super PI 1mb in the phase category.

After tweaking for around 20 – 30 minutes I reached this score.

It’s a 1st but only just.

10 – 15 Minutes after I got this Super PI score, it’s has no competition so that’s in the 1st spot too.

After completing the bench runs I went for maximum CPUZ validation. I got 5.8GHz on Phase. I was running at 6GHz but unfortunately the validation file was corrupt.

To sum up, I’m pretty happy with this chip, it did well considering the slow DDR3 RAM I was running.
I’m very happy with this FX-8120 and I feel it’s at a good price point. Lastly I hope to get a 6GHz validation very soon and update this! Wish me luck.
