Overclocking Comparison
Maximum overclock data was added to Performance graphs beginning with the nForce4 SLI roundup several months ago. The overclocking performance graphs should allow better comparison of the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of a specific board, please refer to the Overclocking and Memory Stress Test section of individual board reviews.
400 at the lower 7x multiplier is truly amazing, and it is the highest value that we have reached in any testing. Keep in mind that this is not our standard base DDR400 overclocked, and is not directly comparable to past results. Therefore we did not include a performance graph with the 400 value with lower multipliers. We always test to see the highest value that we can reach on any board before settling back at the DDR400 overclock. The ULi is just amazing to reach 400 CPU Base Clock in our tests, which certainly indicates a robust voltage regulation with this chipset. We are very happy when we reach a 50% CPU Base Clock OC (300) at lower multipliers. Reaching 100% Base Clock Speed OC (400) is rare.
ULi's claim that a base clock speed of 400 was possible met a lot of skepticism here, but the board did exactly what ULi promised. To be fair, it is mostly just a bragging point and has little impact on performance until ULi also implements the companion vDimm adjustments and expanded vCore to make 400 a true performance booster, but it is still impressive.

^^^ Same. My OC'd S754/Clawhammer plays all current games fine. Seeing as none of the titles I play currently can take advantage of SMP now anyway I am really in no rush to migrate. That combined with the fact my X800 XTPE on the AGP bus still has plenty of bandwidth to spare. Also, the lack of NV drivers for all games to be able to take advantage of 2 video cards makes me lean more for the ATI chipset soloution anyway. My2c..MarkB - Friday, August 5, 2005 - link
How about using the OCZ memory volatage booster card for the overclocking tests.. would be crazy to see performance at 400 FSB and high clocked ram.SpaceRanger - Friday, August 5, 2005 - link
I thought the OCZ Memory thing was just a voltage stabilizer, not a booster. Maybe I am getting the 2 modules confused..Lonyo - Friday, August 5, 2005 - link
Nah, I'm fauirly sure it adds voltage adjustments up to either 3.2 or 3.5v."The OCZ DDR Booster with patent-pending PowerClean technology supplies “cleaner” power to the installed memory modules and allows increasing their voltage above the rated one"

"in the extreme right position, the memory receives a voltage of 3.9v."
It would be a little unfair since no other tests have been run with the booster, but it would be nice to get a sneak peek at possible performance of very high speed RAM with AMD64 and a high FSB. Some nice OCZ VX in there with the booster and 3.5v or so would be something worth seeing.

Wesley Fink there are some questions unanswered, yet.The performance in IDE and SATA is impressive.
Does it have SATA NCQ?
You should also ask about this riser card, because the final version must have 3 PCIe 16X slots, with 2 working has 8X, I doubt that the riser card is a good working solution, because if I put the board in a case how can I connect the monitor cables or even insert the cards on the riser ?
Also how does it have 2 PCIe x4 (or x2) if it has only 20 PCIe lanes, or does this mean only one will work in 4X mode and 2 in 2X mode?
Also ask about when we should expect mobo’s with those chipset start selling?

Yes, ULi tells me this south bridge board does support NCQ - as do the coming M1573 and M1575 south bridges.I do not know the final solution on the riser card. This is a Reference Board for qualification. Manufacturers will decide what they wish to implement. As I stated in the review I do agree the riser is not a likely production feature.
As you can see in the BIOS picture on page 4, the options are 1 x4 or 2 x2 - total 4 lanes added to the 16 equals 20. ATI actually has 22 lanes in their chipset and use the extra 2 lanes for communication between north/south bridge.

Notice that in the BIOS screenshot it says:1x16 1x4
1x16 2x2
2x8 1x4
So, you have a choice of running 1 x4 card or two x2 cards.
Can you run x4 cards in an x4 slot at x2 speed? Heck, where are the x4 cards anyways, can't say I've actually seen an x4 slot on a board before, either.

I asked ASrock's US sales division the same thing. They said the "939Dual-SATA2" motherboard will not be available in the US market. Of course, I'm not too sure if that is unshakable or not. They may or many not release it here; however, they may do it but just in a different flavor. Your guess is as good as mine. I love the reviews pumping up this chipset, but I have yet to find anything solid as to US releases. Guess I will just sit patiently and wait.lsman - Friday, August 5, 2005 - link
OCworkbench.com review this board as these jumpers are for"FUTURE_CPU_PORT"...Socket M2..
so may be the board to look for..

Anyone know where/when to get one of these. This is exactly what I need, as I and probably thousands of you have an AGP card and don't want to spring for PCIe yet.
