I'll start checking around.

Hahaha, yeah. It's easier to give a thumbs down when it's not your money. Hope you find a good matched set at a good price. What's the top IC's for DDR2 and DDR3 these days? Are those Micron chips, the ones to have?

Here's Anandtech's review of top DDR RAM
http://www.anandtech.com/memor...owdoc.aspx?i=2676&p=1

and their latest DDR2 roundup
http://www.anandtech.com/showdoc.aspx?i=3476&p=2

Couldn't find a descent DDR3 review though... at least nothing current.

Thanks for the links. I'm not sure which IC is a the top of the heap now.

I swapped out the 6400+ for the 9950 phenom today and had my sticks clocked to 1204MHz but ran out of time before I got the system stable enough to run the Everest memory test. Maybe tomorrow if I find the time.

Just remembered a trick to optimizing your RAM for your system. Most Asus boards, even socket 939 (at least the late model ones) and pretty much all modern motherboards now have an option in the memory configuration for DRAM bank clock skewing. Most of the time, people just leave it at the auto settings since this ensures easier overclocking of the RAM. If you have some good overclocking RAM, or higher spec'd RAM than what the motherboard and CPU is capable, try manually setting the RAM clock skewing to normal. You'll have to start at the basement; i.e. your default clocks and gradually work your way up, but the benefits can be pretty good if you can run normal or no clock skewing all the way up to your maximum overclock. Even if you can turn the advance back a step or two at the high-end, it can increase your bandwidth and latency scores.

I noticed a big improvement on my system, just at stock clocks. I haven't tried a massive overclock, so I'm still well below my 500MHz DDR rating and running it in normal mode so far. I noticed a far snappier system, even when clocked at stock clocks on my entire system. I'm running a much smaller overclock now (8%), and achieving bandwidth scores around the 10% range. Again, this is on my old system, I have yet to try it our on my parents Phenom system with their standard 1066MHz Mushkin RAM running at tighter latencies at 800MJHz.

I really don't like fooling around their system and the memory, becasue if it doesn't take, it means pulling the CMOS jumper cap. It's not a real enthusiast motherboard, and not as easy to recover a failed overclocking attempt, or incorrect memory settings. That, and all their DIMMs are populated making it much harder, but when I get some time I'll try to post back here with the synopsis.

I ran some Everest memory tests with the new AM3, DDR3 system but as you can see in this case speed doesn't kill but CL9 does (the bandwidth that is).

DDR3 still in it's infancy really,i'm using G-Skill 8500's and not far behind the ddr3 theoldtimers using,albeit i was ganged mode,gives the best bandwidth,lol!!

At the speeds the system and memory are running if the CL was down around 7 rather than up at 9 I would expect the read score to be in the high 11,000's if not above 12,000. Just MHO though because I don't have any DDR3 1600 CL7 to prove it.

Another score,DDR2 8500's not any worse than the slowest DDR3's in my opinion,dont forget AM3 and DDR3 still very new technology,but i am sure AMD will perfect it soon.

Here is one with the memory ganged I had to drop the
Fsb one tick to stabilize the system though.

I rest my case,lol considering your memory bus is 300mhz faster than mine,not a lot in it is there,??.

Bit closer now,lol!!!

I worked with the memory a little but at 100MHz over it's native best rated speed I haven't found much there so far. I may lower the overall speed and see if I can tighten the timings. It's getting better though.

Sorry guys, I'll update the benchmakrs tomorrow. Just been busy with renovations, work and Windows 7 RC, hahah... though it looks like you folks have been busy too!
