While I’m leaving the FAH test to run for a few days I decide to give some thought to the kit.
A few of these images you have seen before.
The motherboard
Biostar TA890FXE
AMD’s latest 890FX chipset is supposed to be overclocking friendly with 2 PCI-E x16 slots.
OC3D has already reviewed this board, so I’ll try not to do the same.
It looks a solid enough board, the heatsinks covering the north bridge and voltage area are quite chunky and dark looking with a gunmetal grey colouring.
Now let’s delve into the dark recesses of the BIOS.
First to catch my eye is CPU configuration, or rather “Core levelling”.
Set on Auto all cores are enabled.
Set to manual to turn off cores if you want to. Turning off cores reduces the amount of heat generated by the CPU.
It’s been mentioned that setting core affinity may have the same desired effect, but you still have four active cores generating heat.
Marsey99 stated in response to a post “Think of it a bit like a 4 bar electric fire with all 4 bars on, then with only 1.” Nuff said.
Another thing is “Smart multi-core” found in the boot tab.
I can’t find any reference to this in the manual, yes! I do occasionally read them.
I even read the bios manual which downloaded with the regular manual in 1 zip file. It’s not even in the screenshot they use.
I can only imagine that if I disable any cores then I should really disable this.
Ok. Now the overclock section which on this board is in a tab called T-Series
BIO-unlocking. Again there’s no mention of this in the manual. I know it enables unlocking extra cores if they’re available.
It would just be nice to see this stuff documented.
Automatic overclock didn’t rock the world. I had to check in cpu-z to see if it actually done anything. 3.8 gig, what’s that. Put it on manual.
Over Voltage configuration.
Something I can’t find is the Vdimm setting. This is the only place I’ve found where I can affect the memory voltage, same for the HT and South Bridge.
You can mix these settings with the VID settings to fine tune the voltages.
CPU FID/VID Control
Disabled is the default setting, once enabled you have control. I haven’t yet been able to max out the voltage on the north bridge yet.
I did try once, but all I got for my trouble was a screen telling me there had been a fatal error and to contact the vendor.
The core VID maxes out at 1.55 and for some reason there are four settings that read 0.0000.
DRAM Timing Configuration
There’s a couple of screens to visit in this section. Biostar memory insight shows you what the bios is reading from SPD spec.
I don’t know what to take from these readings.
The bios automatically sets the memory to 1333 CL9-9-9-24, so is it also setting the memory to 1.25v, where’s the Vdimm control.
In fact, when I installed Toverclocker it showed the Vdimm as 1.5v
Memory Clock mode
After setting this to manual, choose which speed to run
While it’s fairly easy to find your way around this BIOS, it’s still a bit of a challenge to overclock.
Recovery from a bad overclock is there, but it failed more often than it worked.
The BIOS needs a bit of improvement, it doesn’t feel quite as polished as others I’ve used, and it’s a bit unstable at silly overclocks.
Even so, it has the X4 970BE folding stable at 4.23GHZ with the Kingston DDR3 1600 at 1736MHz. That’s not too shabby really.
The processor
AMD Phenom II X4 970BE

The X4 970 BE runs at 3.5GHz on a 45nm fabrication process with a 125W TDP.
With 128KB of Level 1 and 512KB of Level 2 cache per core and 6MB of shared Level 3 cache.
I read on some websites that there are some extra cores to be unlocked, with the right motherboard.
Other sites have said it depends on the batch no. We will see.
This CPU is no hotter than my old Intel QX6700, which had a TPD of 130W but only ran at 2.6GHz.
Overclocking wise I can’t fault it, although I don’t think this motherboard really does it justice.
So far I’ve only managed to coax 4.56GHz out of it.
Considering that’s using an air cooler, it’s than I’ve managed on most of the CPU’s I’ve clocked on air.
The cooler
The Scythe Susanoo
So much has already been said about this cooler, what can I possibly add.
Showing you a picture of the box doesn’t do it justice.
This is a better picture.
4 100mm fans sit on it’s top, coupled with a fan controller to control all 4 fans.
Yes, it’s massive, but it performs as well.
This is folding 24/7 at 4.23GHz for four days now, and it reached a max temp of 51c in a room temp of 26c.
You’ll have to excuse the poor quality of this pic. I was focusing on getting the thermometer readings to show.
It’s been a warm couple of days recently, and considering I’m using 1.51vcore that’s pretty impressive.
The DDR3 RAM.
I’m still in love with this stuff, please can I keep it, huh? Can I?
I won’t go as far as offering fealty or anything like that, but maybe a live sacrifice to the gods?
I mean look at it. Doesn’t it look so at home there? Gorgeous.
Oh, right. You want to know about performance.
1960MHz with CL9-9-9-24 timings using 1.5vdimm SuperPi 32m stable.
That’s impressive enough for me. At the moment it’s running at 1736MHz for the 24/7 FAH test.
Got some more to do when that's finished.
