P5K-Deluxe and T1 Command Rates Results

post #1 of 2
Thread Starter 
So I've been playing with this and I find something quiet odd.

The board wont post what so ever with the command rate at T1 and the memory at the lowest divider linking it to the FSB.

All memory speeds and timings below are with 4-4-4-5-T1 except for the testing of 533 at 5-5-5-15-T1. I did all testing with 2.35v except for the first try at stability at 533.


266FSB - 533Mem = No post at any relaxed latencies or voltages all the way to 2.4

266FSB - 800Mem = Full stable boot into windows and pulling memory read and latency benchmarks just fine.

350FSB - 700Mem = No post.

350FSB - 840Mem = Full stable boot into windows and pulling memory read and latency benchmarks just fine.

375FSB - 750Mem = No Post

375FSB - 900Mem = Full stable boot into windows and pulling memory read and latency benchmarks just fine.

400FSB – 800Mem = No Post

400FSB – 960Mem = Full stable boot into windows and pulling memory read and latency benchmarks just fine.


So it's very odd. Sadly I couldn't get great bandwidth or latency because my cpu core speed was crippled because I couldn't go over 400MHz FSB because my HZs will not go over 960MHz at T1.

If you have a processor with a higher multi you can use the great memory multipliers and achieve a high cpu overclock while using sub 400MHz FSB speeds.

Edit

So I find for myself I get the best memory Latency and Bandwidth using 480MHz FSB and 1200MHz on my memory with 5-5-5-15 @ 2.3v.

Interesting to see. Apparently 1T timing on ram is still proprietary to the 680i and 650i chipsets.
