Overclocking PC4000 "eased latency" memory?

I have 2 sticks of 1gb memory (2gb total) in my system. I never had much luck overclocking my Newcastle chip, maybe 200mhz max, no matter what memory or settings I used, so I have never pushed this memory to its limit... With my new Opteron 170 on the way, I do plan on overclocking some...

However, I'm not sure what advice to follow. Most advice I see is for memory that has more agressive timings, not memory that has "eased" timings. Apparently the goal on this memory was to ease the timings to allow a higher mHz to be reached on the memory (as opposed to simply getting much more expensive memory)...

The memory is Patriot 1gb PC4000 eased latency. All I know about the ratings are as it says on that page:
* PC4000 at 500MHz
* Eased Latency of 3-4-4-8

CPU-Z shows currently it is running at: 200.2MHz, CPU/5, 2.5 Cas Latency, 4 RAS2CAS, 4 RAS Precharge, 7 TRas, 11 Trc, 1T Command Rate, 16 Clocks DRAM Idle Timer...

The SPD info shows 200MHz @ 2.5/4/4/7 and 250MHz at 3.0/4/4/8... since my A8V won't let me manually select 250MHz for the memory rate, I guess I just set the 3.0/8 manually, and overclock up to that rate if possible?

I haven't had any problem with the memory - I'm assuming it is giving me CAS 2.5 since I'm not running it at 500MHz, but rather at 400 (PC3200 territory)...

Should I be able to increase just the CAS and Cycle Time in BIOS and expect to come anywhere near the 500MHz speed as I overclock, or are there other values I need to massage?

Thanks!

So... when setting the timings, what should I keep in mind specifically - what settings might I need to
