I will be building a new computer in a couple of weeks and saw this RAM and was wondering if anyone knew anything about it. I am pretty sure that they don't use the Micron D9 chips but does this really matter. I'll overclock but not likely over the standard rating of the chips.

On different note I'm going to be pairing this with an E4300, how are these clocking? I've also read some stuff about setting these to the 1066 strap and was wondering how hard this was?

Cheers for any help.

So PROMOS chips are still good? Not the same level as Micron though?

I am using this memory currently. I bought it when it was 199 at newegg, and although it is now 105 at newegg, i'm very happy with the RAM.

At stock (2.1V) I can run 450MHz at 4-4-3-5 timings. If you loosen the timings i have gone to 505MHz at 5-5-5-15. Right now I am running them 4-4-4-12 at 500MHz with 2.2V. I also experimented with 3-3-3-5 timings at 350MHz but my performance was a little better with higher clock speeds and looser timings. My motherboard doesn't support changing the command rate, but i'm sure these would be capable of decent speeds with a 1T command rate if you have an nvidia chipset that allows the change.

Buy these!!

I'm using 1 stick of 1GB of this memory on my DS3 but I seem to be topping out at 450MHz @ 5-5-5-15 @ 2.3V....

The Promos chips aren't as high quality and don't scale as well as D9's but they sure are decent overclockers. I have seen several reviews (will post these when I get home) with these easily hitting 500MHz. Even stable at 571MHz. Even booted at 600MHz but was unstable so....

1) What am I doing wrong?
2) Is it that 1 stick overclocks worse than dual?
3) How can I stably take it higher?

I would check the 5th number. Supposedly these modules run 4-4-3-5-24 but I have found that the 24 is often too low except at stock speeds so I upped mine to 40 and it eliminated some stability problems. Some people have reported that higher voltages cause instability with these PROMOS chips so I would back down to the highest stock voltage (2.1) and start over.

Begin at 400MHz and start increasing the FSB by 10Mhz and run a few passes of Memtest86 and if you don't have any errors, then increase again.

Also, the DS3 is not the greatest board for memory. On my DS3 (Rev. 3.3) Every time I change memory timings, the computer has to shut itself off and give itself some time or something. It is strange behavior that I haven't seen on any other boards.

Rather interesting. It seems as though I might have been going about it all wrong with the increased voltage and just pushing the stick I have based on reviews that have tested the 2GB kit of this same memory.

Link didn't work quite right. I meant this stuff. Super Talent T800UX2GC4 - 2GB kit, 800MHz, PC6400, 4-4-3-8 latency

twjr, for 160 US, I would just get someone in the US to buy it from Newegg for 105 and then ship it to Australia for approx 20? and then just give them 10 for the hassle? save yourself $25 maybe? Not sure what it costs to ship to an Aussie.

I don't really like doing the whole international shipping thing as well as money issues. But mostly I know no one in the States. Also I live In New Zealand I'm just going to be In OZ in a couple of weeks and thought I would take advantage of some cheaper prices. From my little experience with shipping with Ebay it costs between $20-40US to ship stuff here. Money is not the issue anyway I'm more worried about the performance difference between the G.Skill and Super Talent Ram and whether they are good value for money.
