FSB Overclocking Results
Memory Stress Testing
Memory stress tests look at the ability of the ASRock 939SLI32-eSATA2 to operate at the officially supported memory frequencies of DDR-400, at the best performing memory timings that the OCZ PC4800 Platinum Edition will support.
The ASRock 939SLI32 was extremely stable with 2 DDR modules in Dual-Channel mode at the settings of 2-2-2-5 at 2.7V. We will now install all four available memory slots that result in more strenuous requirements on the memory subsystem than testing 2 DDR modules on a motherboard.
The ASRock 939SLI32 was very stable with 4 DDR modules in Dual-Channel operation at the settings of 2-2-2-8, but required the command rate be increased to 2T that is typical in AMD Athlon 64 based systems.

This board would cannabilize sales of the premium SLI32 and xfire board that Asus sells for $150 IF it included voltage settings up to 2v vCore, 3.2v vMem, etc.They would be stupid to do it. These people will pay the $150 anyway if they don't have an easy (cheap) alternative. For the rest of us, we can get busy with a 2B pencil, solders or conductive ink. ;) And forgo the warranty on it, so if it goes boom in a year's time, you're on your own.
Nice strategy. Would AT leak the beta bios for comparison's sake? (We'll smuggle it to xs or ocwb....:D)

and for the record the dualsata2 is a very stable mobo @ stock settings, i have to give credit where it's due, but for overclocking this company's products shouldnt even be considered.sandorski - Thursday, March 2, 2006 - link
It kinda sucks Nvidia bought out ULI, they were very innovative and really filled niche markets very well. Then again, perhaps Nvidia will let them continue doing interesting things there?Cygni - Thursday, March 2, 2006 - link
Hard to argue with that... looks like ASRock/ULi has another mega seller on their hand with this baby. But I cant help but wish it had an AGP slot thrown in between the two PCI-Ex lanes, to allow an upgrade path. Thats probably the primary reason the ULi 1695 boards have been selling so well.The IDE and SATA performance numbers are really striking in contrast to Nvidia's. I hope we see the inclusion of ULi's storage controller in future Nvidia chipsets.
All for $85... awesome.

If it had an AGP slot then it would have to use ULi's AGP tunnel + the 1697 instead of the 1695 + 1697, which would mean that it'd only have 16 PCI-e lanes for graphics. I suppose most of us wouldn't mind going for two 8x slots while in SLI but then most of us wouldn't really want SLI to begin with.JackPack - Thursday, March 2, 2006 - link
Quality doesn't seem to be bad either. Panasonic and UCC caps in there.
