AMD 64 socket 754

[kxm9976]

hello,

my question is whether the dual channel ram is good for socket 754.

Thanks

The ram will work, just not in "dual channel" mode.

 

[stelleg151]

and ram generally runs better in only one dimm on the 754's so the overall answer is no I think.

dual channel ram is fine for s754, s754 jsut doesnt support dual channel.

 

[effee]

Yea, but it is a waste of money, if you are going for DC ram, then just get something 939

There is no down side other than cost to using dual channel tested memory on the 754 platform.

When a memory manufactuer claims they are selling "dual channel" memory they are simply stating that the memory has been tested for dual channel usage and passes some test. The memory itself is not different in any significant way, only that the two dimms match and compliment each other IF used on a dual channel system.

Thanks everyone for you answers.

The reason I asked is because I have my eye on this one Ram by OCZ (PC3500) which is only offered in dual channel ram kits (1 GIG, 2x512) on Newegg. And for the comp I am building I need 2 512mb Rams.

The same model ram but PC3200 is offered by Newegg in 512 sticks.

So if the dual channel rams are the same rams as the ones sold separately, for the same money it is better to go with higher DDR, don't you think?

In any case, do you think any of the above mentioned rams should go well with my DFI Lanparty UT 250 using two 512's at stock speeds, with a potential oc'ing in the future.

Thanks everyone.

P.S. What you guys think about Kingmax PC3500, PC3700, PC4000. Are they any good. They sure are pretty cheap.

One more thing,
by using two dual kit rams in my computer (amd 64 socket 754), do I sacrifice the performance?
Thanks

Socket 754 DOES NOT SUPPORT DUAL CHANNEL.

It already benefits from on-die memory control so it wouldn't be a big deal anyway even if it did support it.

Buying RAM in "Dual Channel Kits" is somewhat of a marketing thing. Cuz really all it is is buying two exact same sticks of RAM. which you can do individually. (and it sometimes cheaper that way)

I konw many ppl have done dual channel with just two plain Samsung PC3200's.

Thats all reply.
That's exactly what I was thinking, but for some reason none of these vendors wanna mention that these dual channel rams will also work in a single channel mode on socket 754.
I guess in that case, I ll go for the OCZ PC3500 Performance series for $208 dual channel kit Ram (2x512)
instead of buying the single PC3200 for $104 each

That should give me a better performance at stock speeds and DFI seems to like the rams made by OCZ.
And in the future if I do decide to oc, the PC3500 should give me more room for breathing.

However there are two things that still bother me a lot and I haven't quite understood the concept behind them.

I plan to run my AMD 64 3200+ at stock speeds and the same with the RAM.

1)
I am gonna use 2 sticks of 512mb Rams for total of 1GIG.
For example these sticks are PC3200 and the cas is 2.5-3-3-7 and the 1GIG (PC3200) is cas 3-4-4-8 (for example).
In this case which one will perform better at stock speeds?


2)
The OCZ's that I mentioned earlier I think have the same cas timings. Is the PC3500 going to perform better then the PC3200 at stock speeds? Also, if I plan to use 2 512's, what is the highest speed (MHz) Ram to get which will perform and work the best at stock speeds?

Thanks a lot everyone

It is all about the latency with AMD64 memory. You want the lowest rated memory possible with the highest HTT (FSB) [or stock] you can get at 1t timings and 1:1 ratio.

2.5-3-3-7 is faster than 3-4-4-8 memory. The 754 still supports 1t timings on two dimms. If you are using the NForce chipset you want the last number to be 10 or 11 for some reason it has been shown to be faster. That is where you go into the bios and change the number. For example you would set your timings (dual PC3200 kit) to 2.5-3-3-10 for optimum performance on the NFORCE chipset

Often the PC3500 memory with have more relaxed timings to achieve the faster frequency so it would actually be slower at PC3200 speeds than regular PC3200 but this varies so you have to look at each memory module (or package) and make sure you get what you want. Then you can often tighten PC3500 memory speeds when leaving the memory at PC3200 speeds but not always so you have to be careful in choosing your memory
