I've got the Striker Extreme board. I've got Crucial Ballistix DDr2-1000s, but I'm not trying to run them at that speeds. As I've said on other threads (very current ones), I'm running these below DDR2-800 speed 1:1 with latencies as low as 3,3,3,6. With two modules -- 1T command rate is very stable. Of course, with four modules -- it's gonna be 2T. I just added a second pair, and need to experiment more.
I think the real question is "What are you trying to do with this Striker board and your Crucials?" What over-clocking strategy are you using?
You might get some insights by going to
www.i4memory.com and looking for posts by someone going by the handle "EVA2000." He (it's a he) -- has developed an entire list of Striker over-clocks at different ratios and memory timings. The worst part of it is this entire catalog of Striker settings was obtained using earlier BIOS versions, although there may be some there with versiion 1004. In the earlier versions, there were discrepancies between "set" VCORE voltage, actual measured VCORE, and sensor VCORE readings. Those BIOS versions that had that problem were earlier than version 1004 -- and either 3XX, 5XX or 7XX versions.
I've since moved up to 1303, which ASUS took off their BIOS download list when they posted version 1305. 1305 doesn't post, and I'd cleared the CMOS. I re-flashed to the 1303 download I got in late July, early August. If you check the Striker forum posts at the ASUS Forums, you'll see that others had problems flashing to 1305, and some made success by doing some fiddling with the battery in addition to clearing the CMOS.
The 1303 version, if you can get it, seems to be perfect for me.
I know everyone wants to OC to 400 and 500 Mhz, but I'm impressed with this board and my ability to OC in 1:1 ratio to 3.2 Ghz and very low latency settings with the Crucials. I was able to get it up to 376 Mhz (CPU_FSB) in 1:1 at the 8 or 7 multiplier, but I'd rather run it at 9. Like someone said, CPU core is king. But -- true -- large L2 cache with fast memory is a boon. But then, what's wrong with an 8,000 MB/sec read memory bandwidth at 3,4,4,8, 1T and between DDR2 speeds at 712 to 720?
