ASRock 775Dual-VSTA
Basic Features
The ASRock 775Dual-VSTA is a very unusual board at a low entry price of $55. It is true that ASRock sometimes marches to the beat of different drummer, and the 775Dual-VSTA is certainly evidence of that. If nothing else, you can say they offer some very uniquely configured boards that offer very good quality for the money. This board features the VIA PT880 Pro Northbridge and VT8237A Southbridge with VRM and BIOS updates that now fully support Core 2 Duo. This is a board that you really want to dislike from a performance viewpoint, but you have to like it from an upgradeability perspective. Well, at least for those users who want to bring along their DDR and AGP cards while buying an E6300 CPU as an example.
The board is laid out nicely and certainly caters to those who value IDE and PCI devices. The VT8237A only supports two SATA 1.5Gbps drives but the board does support four IDE devices. The overall feature set of the VIA chipset is the same as the Biostar PT880 Pro board we reviewed a few months back.
Basic Performance
The performance was not as bad with a Core 2 Duo as we had expected. In fact, in almost all of our benchmarks the board was at least in shouting distance of the other contestants. We actually found the DDR2 memory performance to be very competitive with the other boards, although support is limited to DDR2-533 and DDR2-667. We just received an updated BIOS that allows greater DDR support and improved timings. We will provide these performance results when we compare the board to an Intel 865 based board that supports Core 2 Duo in the near future.
The other potential issue is a PCIe graphics slot that only supports X4 operation. This proved to be an issue in benchmarks that tend to stress the GPU interface. Although ASRock only lists official PCIe support for video cards such as the NVIDIA 6600/6800GT or ATI X700 range, we had no difficulties running our ATI X1900XTX or EVGA 7900GTX in the board - though we never quite trusted it due to power delivery concerns. The board on a couple of occasions while overclocking completed a brown out while either GPU was being stressed in 3DMark06. In the end, you are paying around $55 for a board that can handle your older or newest peripherals and still provide a decent level of performance. We have to hand it to ASRock on fulfilling these requirements with a stable board, but we look forward to their Intel based value boards which should be arriving shortly.
Overclocking
We did not expect much in the way of overclocking with this board and this is about what we got. However, the board did overclock further than we expected - a pleasant surprise - and we almost reached the 300FSB level with our test components. The board actually reached a 303FSB setting with an NVIDIA 6800 Ultra AGP card and some inexpensive DDR 333 memory. However, anything higher resulted in a no boot condition and clearing of the CMOS. In the end, you get what you pay for, although sometimes there is a surprise in the box of chocolates. We were surprised by this board, first for its ability to operate fine with a Core 2 Duo, and secondly that the general performance of the board was actually very good overall considering its heritage. It was kind of slow at times, but it still managed to consistently finish the race.

Im curious, can you go into some detail as to how you determine each memory's stable speeds at the various timings you reported?Did you test any of the value ram up to 1067 or would they not work at all?

Too bad you guys didnt test the asrock conroexfire, its basically similar to the one you tested now but with a 16x pcie slot and only ddr2 support.Gary Key - Wednesday, July 19, 2006 - link
We have more boards coming, the flood gates are getting ready to open from the motherboard suppliers over the course of the next four weeks. Although the press embargo release was moved up to last week, the motherboard suppliers were still targeting 7/27 for hardware releases into the market. We will review and post articles on Conroe capable boards as soon as we receive them. We still have some very good AM2 boards to review also. ;-)

Can you guys run a few benchmarks with DDR1 on this board? It doesn't have to be the full suite, just some to get an idea of DDR1 performance with Conroe. Thanks!Gary Key - Wednesday, July 19, 2006 - link
We are testing another DDR1 board shortly and will have those results up in the near future. Bios version 1.3 on this board improved DDR1 performance and we are expecting another bios spin shortly.

What board is that? Another ASROCK? They have quite a few Conroe compatible ones based on VIA, ATI and the i865G chipsets.
Gary Key - Wednesday, July 19, 2006 - link
Yes, we will be testing the ASRock 775i65G, there might also be a i865 board coming from PC Chips. We should see some additional value based boards in the near future from other suppliers based on the 946PL and SIS662 chipsets.yacoub - Wednesday, July 19, 2006 - link
Lists chipset as: Chipset Intel 975X + ICH8RI thought it was 965?
yacoub - Wednesday, July 19, 2006 - link
And on the same page:"Despite the similarity of the ASUS 975X and 965 top boards, a closer look at options does tell you 965 is targeted a bit lower than 965. "

Fixed - as you can imagine given the length, there will probably be a few more typos than normal. Our heads are all spinning a bit after putting this together. ;)
