Mushkin eXtreme DDR2-667
The Mushkin DDR2-667 memory arrived with the highest price in our value roundup, an excellent heat spreader design, but performed below average at the DDR2-667 and DDR2-800 settings. We raised the voltages but did not have any success in improving the timings at these settings. However, the Mushkin ran at stock voltages for the low latency DDR2-400 and DDR2-533 settings although the 3-3-3-8 timings at DDR2-533 could not be improved with additional voltage to match the 3-2-2-7 timings of other modules. Also, this is the only memory in our group that would not run 4-3-3 settings at DDR2-800. Although the performance difference is minimal, the cost of this kit indicates the memory should perform better.
Patriot DDR2-667
Patriot Memory provided their Extreme Performance series memory modules that provided above average performance at voltage settings that were more than acceptable for 24/7 operation. The memory comes with stylish heat spreaders and was able to easily clock up to DDR2-900 at extended voltages and 5-5-5-15 timings, though we recommend the lower latencies at DDR2-800.
PQI Turbo DDR2-667
The bargain of the bunch has to be the PQI Turbo kit that is currently selling for around $117 with rebate. While the timing performance of the memory was excellent we had to run at voltages higher than the group's average to meet these settings. The base voltage for this particular model is 2.0V, something to be aware of based upon our results with the other memory modules.
Wintec AMPX DDR2-667
The Wintec AMPX DDR2 Extreme series of memory was the pleasant surprise of the group as it generated excellent timings at low voltages at the lower memory speeds. It performed average at DDR2-800, although the results are more than acceptable.
Comparing Value Memory
All of the memory in the value section was able to run on average 4-3-3-9 settings at DDR2-800 except for the Mushkin modules that were limited to 4-4-4-12 but at a low 2.0V setting. The performance delta is extremely minor and the lower voltages are welcomed, but the Mushkin memory is the most expensive in our group so we naturally expect more from it.
The ability of all our value memory to run at very low latencies at DDR2-667 and 4-3-3-9 latencies at DDR2-800 is just incredible given the average price of $148 for a 2GB kit. Not even a year ago this type of performance in the DDR2 world would have placed this "value" memory at the top of performance charts. We found the Elpida memory to offer higher overclocks at lower memory voltages overall than the Infineon based modules, making it the current leader in value performance memory in our opinion.
The two modules that stood out were the A-Data Vitesta DDR2-533 and Wintec AMPX DDR2-667. During testing, both offered a unique combination of price, performance, and stability. All of the memory reviewed is more than acceptable for a Conroe system and the performance differences are so minor that we suggest choosing a supplier based upon prior experience, warranty, or price in this case. We will be looking at additional value memory modules from other suppliers shortly along with providing performance test results with our new Core 2 Duo Memory test platform.

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. ;)
