The ASRock 939SLI32-eSATA2 is a member of the Socket 939 Series product family and is a value-based board targeted towards the enthusiast user. The board ships with an accessory package that includes the standard assortment of IDE/SATA cables and power connectors. ASRock also includes an extensive driver CD along with desktop utilities.

This is the BIOS setup utility screen, which displays the change configuration categories available on the board.

This is the Advanced BIOS category main screen that contains all of the subcategories available for setup.

The CPU configuration section allows you to set individual parameters manually for voltage, multipliers, and chipset frequency settings. Unfortunately, one of the few issues that we had with the board was the limited CPU voltage settings. The system would not allow a setting over 1.4V for our 4000+ or Opteron 170 CPU choices. The Boot Failure Guard option is a BIOS recovery setting that allows the system to recover from errant overclocking settings. The system worked superbly as we never had to use the clear CMOS jumper.

The CPU Configuration screen also contains the section for controlling memory timing adjustments. The BIOS allows for an Auto setting that will set the memory to the SPD settings or you can adjust the memory timings manually. The Flexibility Option will override the manual settings based upon the ability of the system to operate properly at the requested memory settings. We typically found in our testing that the system would adjust the memory clock settings based upon the latency settings utilized.

The Memory Clock settings are fairly limited on the board with the Auto setting providing an adjusted ratio dependent upon the manual memory settings and bus speeds. The other three memory settings will lock the given memory ratio to the CPU clock.

The Chipset Settings configuration screen allows you to adjust the North and South Bridge link speed and width settings. The voltage adjustments for memory and chipset are also available on this screen. The memory voltage was only adjustable up to 2.8V that definitely played a role in our overclocking results along with the limited CPU voltage settings. We also do not like the memory and chipset settings being alpha instead of numerically based.

    I see, I'm still interested to see how this Epox board overclocks, I look forward to the Anantech review. If its priced similar to the Asrock Sli but with better voltage options I will get one despite it being x8 x8 ... thanks for the info.

    fantastic!!! I rate Epox boards highly, I'm waiting for that particular board to make an appearance in the UK ... I look forward to your results! Reply

    I am looking to build a system for my 15 year old son who does video editing as his system stressing function, not gaming. We do video editing on my own aging but still quite nice FIC AU13max, Athlon2500+, All-in-Wonder 9700pro, 1GB (2x 512)PC2700, system that I built 3 years ago (my only other previous build). I want to build a system that will be good for video editing primarily but provide for gaming should his gaming interest change from his Playstation2 to his PC. I would build my own system and pass my old system down to him like I did last time, but really like the DVR/home theater I have set up with my TV, JVC 9010VBK receiver, and AIW AGP card.

    Anyway, things sure have changed since my last build! I could use a bit of guidance. I am considering this board and would like advice on the least expensive (as a baseline, I will work my way up from there budgetarily) CPU, memory, video card, etcetera that would serve the aforementioned needs.

    To add a bit of complexity to my question (I hope this off topic diversion is ok) I had been considering a DFI LP UT NF4 Ultra-D mainly for the future potential if he gets into overclocking and such as well as the cool factor with a uv lighted case. Some reviews gave this poor marks for stability at the default settings which sent me looking elsewhere like here. Does the X2 support of the ASRock 939SLI32 warrant going with a dual core and this board for multitasking capability?

    Thanks for your assistance.

    my $.02
    I just RMA'd a defective Ultra-D. The power requirements are very high, as it is capable of severely overvolting your hardware. It is also a very advanced board and may be difficult to use in many situations. Read at before purchasing system components if you're serious about this avenue.
    Perhaps he would be better off with a less demanding, more user friendly board like the Asrock board or an Asus offering.

    Thanks for the heads up. I was a bit apprehensive about the reviews referencing compatibility issues on the DFI. This ASRock seems interesting. Asus seems like people either love'm or hate'm. I tend away from mainstream as evidenced by my FIC Mobo which appears to be one of the last of the line. I guess I'll keep on looking to see what I come up with.

    If I go with the ASRock any component suggestions? Any other specific components that I should avoid?

    Great to see the new way of presenting the gaming benchmarks. The "min" numbers are especially useful. Nice and easy to understand as well. Keep up the good work! I hope you will continue to use this in all your gaming benches. With the reports/speculation of Nvidias next high end offering being close to ATIs X1900XTX in the sense that it will beat it in some and loose in others this extra info might be the decisive factor.

    I don't like it. The layout is not very good. The chipset heatsinks look crappy. It seems like the southbridge heatsink is too high and will be in the way of expansion cards. And why a 20 pin power connector? I want 24 pins, especially because this board supports sli. I think I can find better for this price, but maybe that's because I don't care about 16x pcie slots.

    Can anyone confirm what (if any) Zalman HSFs are compatible with this motherboard? Reply
  • Gary Key - Friday, March 03, 2006 - link

    Zalman CNPS-9500 - Yes
    Zalman CNPS-7700 - No
    Zalman CNPS-7000 - I do not have this item but looking at the measurements it would be extremely close, taking the measurements off the 7700 unit in place it might fit but just as easily might not.

    Thank you good sir. The 9500 is what I'll be coupling with this baby. Reply
