i've heard from several sources that the pc800 ram from sammy is better than even the 1066's and the 4200 rimms.

how can this be? and is this what i should get?

i plan on getting 2x256mb for my new th7II and 1.6a :)

converting from a BD7II and DDR.

sammy rules the rdram world. no competition. most brands of rdram are just remarked sammy anyway. kingston cooks there own but watch out for their 1066. it doesnt work very well.

Hmm... I had kingston pc1066 at pc1200 speeds for a while. Nothing wrong with it as far as I can tell....

Hehe Samsung makes PC1066 and PC4200 RDRAM too though. =)

The higher-rated modules should be better by virtue of their latency alone.

I've seen just as good of results achieved by PC800 Samsung as by the newer types. Just like the Samsung original CTL PC2700 DDR, the PC800 Samsung was extremely good memory, capable of operation at speeds well in excess of its rating. As a side benefit TH7-11's show a strong preference for 45ns PC800 Samsung, more so than other boards.

ok so is there any performance difference between the 40ns and the 45ns rdram?

and why does it seem like it would be so much slower than ddr which is now down to 2ns on the latest geforce?

guess what?? newegg now sells 1066 sammys, check it out.:D
sold out. too expensive anyways. 125 bucks for 256mb ram? no way.

and i wouldn't buy 128's so thats not even a consideration since they are in stock.

no bud, you want the sticks at the top of the page, the 184 pin. price $144. for 256, 2x128. i would anyways, if i wanted 184 pin.

you are making no sense.

you say 256mb for 144 bucks is the way to go? rofl no way!!

i can get 512mb of pc800 for 180 bucks.

well, the sammy 1066 HAS GOT TO OVERCLOCK BETTER THAN THE 800. if some 800 does 1200, imagine what the 1066 would do. get the 512 for $180, but i would go with the 1066, and what type of mobo are you gonna use?

TH7II i got for 35 bucks :D

and you won't be able to get 1066 512mb for 180 bucks. cheapest i'm seeing it is well over 200 bucks (not worth it to me)

and as far as the o/c of 1066... i've seen that the 1066 is not o/cing very well from the many posts in the intel section.

well, you my as well get the 800. the th7II for $35 is great, but chipsety no goody. mobo is ok, hope you get a good one bro.;)

chipset is no good?

it seems to hold its own pretty well. there are tons of people that use this board. i've never seen anyone outright complaining about the chipset :confused:

I read a tremendous guide on the TH7-II, and it covered such topics as ram prefrerence. It said the TH7-II liked the 45ns version of the Samsung PC800 above all others, including the 40ns version and PC1066. I'm sorry but I can't remember where I saw the guide, I read about 10 forums and being that I am not a TH7-II owner I didn't make note of the location of the info.

Yes, latency is RDRAM's dirty little secret. The latency of SDRAM, whether it be SDR or DDR is vastly better than RDRAM. This is why DDR systems with lower sandra scores can indeed compete with RDRAM systems posting higher bandwidth numbers. Once you get the DDR system to the same bandwidth level, it is a faster system due to the latency advantage. Back in the single channel RDRAM days PC800 got it's lunch eaten by PC133 SDRAM. Intel had to go to the dual channel RDRAM implementations to give RDRAM systems a large bandwidth edge over SDRAM systems before it finally showed any promise, much less an advantage. As the raw bandwidth of DDR sdram has improved to near parity with RDRAM the advantage that RDRAM posses varies between insignificant and non-existant.

SETI is one of the best ways to judge the actual effectiveness of the memory subsystem, all Sandra BS aside.

http://www.ocsetiteam.com/other/bench.htm

My system just recorded a 2.63 hour result at 2600MHz, fully competitive with JD's (2.59 hour) RDRAM rig at 2700MHz. The top scores have been posted by a P4B533 845e board. The top ranks of 3DMark are becoming saturated by hot 845e's as well, as the 433-500MHz capable DDR that is everywhere today is tough to match.
