Overclocking: ASRock 939Dual-Sata2

Front Side Bus Overclocking Testbed
Processor: Athlon 64 4000+
(2.4GHz, 1MB Cache)
CPU Voltage: 1.55V (default 1.50V)
Cooling: Thermaltake Silent Boost K8 Heat sink/Fan
Power Supply: OCZ Power Stream 520W
Memory: OCZ PC3200 EL Platinum Rev. 2
(Samsung TCCD Memory Chips)
Hard Drive: Seagate 120GB 7200RPM SATA 8MB Cache
Maximum OC:
(Standard Ratio)
242x12 (4x HT, 2.5-3-3-7, "High" voltage)
2904MHz (+21%)
Maximum FSB:
(Lower Ratio)
304 x 9 (2736MHz) (3x HT)
(2 DIMMs in DC mode)
(+52% Bus Overclock)

We certainly didn't expect much with just "Normal" and "High" choices for memory voltage, but the ULi chipset has surprised us once again. We easily reached 242 at stock 12x multiplier - one of the highest overclocks that we have seen with this CPU.

As we saw on the ULi Reference board 2, we could reach all the way to 400 Clock Speed with reduced multipliers and lowered memory ratios. Using our standard OCZ TCCD at rated speed, we still managed to reach above 300, making the ASRock one of the few AMD motherboards that can reach beyond 300 with this memory.

    Just be careful. Asrock rarely upadtes their BIOS, has no support, etc... So if there is a problem, you better fix it yourself.

    Everything you have said is not true, I have owned a asrock k7s8x, asrock k7s8xe+, asrock k8 upgrade 760 gx and now a asrock 939 dual sata 2. I have found their support to be excellent and they only release bios updates when they are needed which is not often because their motherboards are very reliable. My first asrock motherboard the k7s8x was purchased in 2003 and it is still in use today and running perfectly.

    Dear Wesley,


    Can AGP and PCI-express video cards run side by side in the same motherboard at the same time? Could I 2 PCI-express cards and my AGP 9700pro all at the same time for some Triple monotor action?

    Thanks.

    There are uli 1695 boards that do support that (their reference board, for instance), however this asrock board only has (1) PCIe x16 port.

    Also, while running a setup with multiple cards, you would probably want only chipsets from one company, to minimize driver troubles (an ATI PCIe card to go with your 9700)

    erp.

    I just glanced back at the reference board review, and the feat was achieved through the use of a riser card out of the x16 slot, covering the AGP slot in the process.

    ULi touts a "triple graphics interface" meaning PCIe, AGP8x, and PCI, I am unsure of the compatability with an SLI + AGP setup, but I'm sure some inventful motherboard manufacturer will put it into practice if it's feasible

    looks awesome! Perfect timing since my Neo 2 just bit it.
