ASRock 775Dual-VSTA: Does DDR2 matter?

System Configuration
Our memory benchmark system uses the following components:
Our test system represents a blend of performance and pricing requirements for a budget Core 2 Duo system. While the choice and wattage of the power supply could be varied to less expensive alternatives we believe having a high quality power supply is critical for system stability and overclocking potential. The performance of the Seagate 320GB drive is near the top of the performance charts while offering excellent capacity for a cost of around $95. If you are upgrading your hard drive with the rest of the system this drive should be at the top of your list. Our EVGA 7600GS video card choice represents a very good mid-range alternative and ensures you have respectable game performance at resolutions under 1280x1024 for less than $130.
Our board is the ASRock 775Dual-VSTA that features the VIA PT880 Pro Northbridge and VT8237A Southbridge with VRM and BIOS updates that now fully support Core 2 Duo. The ASRock 775Dual-VSTA is a very unusual board considering all of the available upgrade options and is available at a low entry price of $55.
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.
Our memory benchmark system uses the following components:
| Performance Test Configuration | |
| Processor: | Intel Core 2 Duo E6300 (Dual core 1.86GHz 2MB Unified Cache) |
| RAM: | 2 x 512MB Patriot DDR-400 2 x 512MB Transcend JetRam DDR2-667 |
| Hard Drive: | Seagate 320GB 7200.10 (16MB Buffer) |
| System Platform Drivers: | VIA 5.09a |
| Video Card: | 1 x EVGA 7600GS PCI-E - All Standard Tests |
| Video Drivers: | NVIDIA 91.31 |
| CPU Cooling: | Stock Intel Heatsink |
| Power Supply: | OCZ PowerStream 520W |
| Motherboards: | ASRock 775Dual-VSTA (VIA PT880Pro) |
| Operating System: | Windows XP Professional SP2 |
| BIOS: | AMI 1.50 |

What would be intresting would be a maybe running at least the synth benchmarks on another C2D mobo.. with the same CPU,HDD;DDR2 etc etc.This would show us if the mobo as a whole runs at a performance handicap to others mobo or.. as I would hope.. basicly its up or near there in performance with most other C2D mobos with or without DDR2.
If that is the case then the mobo is truly very good for those of us not wanting to shell out 250e+ for 2x1Gb DDR2 when we already have 2x512Mb DDR sat in our current rigs so we could spend that money on CPU/GPU as you wrote in your atricle and maybe get DDR2 later as and when funds become available.
thanks.

You will see this in the final comparison article. The general performance of the board is about the same as we reported in our Conroe Buying Guide. However, the 1.5 bios has improved performance in some areas.

I am surprised how little advantage DDR2 has over DDR memory. Very interesting. Was the difference greater from SDR to DDR? I forget.Locutus465 - Tuesday, August 8, 2006 - link
I'm guessing a higher end board with a better memory controller might show DD2 in a better light.retrospooty - Tuesday, August 8, 2006 - link
The same can be said for DDR.MY DFI Lanparty NF4 runs my Corsair BH-5 chips at 260mhz@ 2-2-2-7 timings. DDR2@ 1000mhz@5-5-5 cant even beat that.

We did a top-end DDR vs DDR2 on the AM2 at http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">http://www.anandtech.com/cpuchipsets/showdoc.aspx?.... Of course, DDR2 bandwidth on the AM2 is huge, even though it doesn't always translate into real-world performance gains. Conroe is not nearly as efficient as AM2 on memory but still outperforms by a wide margin. In the AM2 article we found fast DDR400 and DDR2-533 roughly equivalent, with faster DDR2 speeds providing a bit more performance.It appears with Conroe on a VIA chipset DDR2-533 gains more, but real-world is still in the ball park with DDR400. That may be a commentary on the VIA chipset and may not apply to Intel or nVidia or ATI. However, this VIA board is the first to allow a DDR/DDR2 comparison with Conroe.
There are other boards for Dore 2 Duo coming that will support DDR on Core 2 Duo. For the value builder, it will be interesting to see how this board compares to some of those.

In some instances DDR was quite a bit faster than SDR. I think it gave about a 10% performance boost on average, and up to 20% in a few special cases. It's also worth noting that the ASRock does offer lower performance than other high-end DDR2 boards, but the price tradeoff makes it justifiable.yyrkoon - Sunday, August 20, 2006 - link
Well, if you go by pure synthetic benchmarks, DDR is 5x faster than SDRAM most of the time. Actual application performance, may be different.Calin - Tuesday, August 8, 2006 - link
DDR was quite a bit faster than DDR - just the way it is now with DDR2 and SDR. However, in the budget side of the equation, the processors weren't starved enough for bandwidth, so the difference was very small.I wonder what the results would have been if a faster processor would have been used.
Oh, and maybe the chipset/BIOS isn't optimized for DDR2 performance (as for DDR, all the performance that could have been squeezed in about three-four years of building chipsets was already there).

Did you mean DDR was quite a bit faster than SDR and now with DDR2 with DDR?
