64 Bit CPUs Don't Need High Performance Memory

[DasFox]

I have a X2 3800+ and I was hearing people say around here that 64bit doesn't care about CAS and using high performance low latency gaming memory is a waste.

Is this true and just your good ole Corsair Value Ram will fill the bill just fine?

I was using before Corsair XMS memory C2

THANKS

A64s (and X2s) do very well with whichever ram you use. They do better with low-latency stuff but the benefit is somewhere around 3-5% (just a guess). It has nothing to do with the 64bit-ness of the CPU, it's just that the integrated memory controller decreases the latency penalty when accessing ram.

Yeah, it seems that there is hardly any difference with either high bandwidth or low latency memory in most actual programs. There was a sticky thread in here with several benchmarks showing this, but I think it fell off at some point.

Ahh ok, well I was asking over at Corsair too:

Just keep in mind that it's the on-die memory controller that lets them handle so well with a large variety of memory speeds. It has nothing to do with x86-64 or 64-bit capability whatsoever.

Dividers?

Ok over at Corsair's forum someone mentions this on that URL I posted:

You will get more of a performance boost from high performance memory on an X2 system then you would on a Socket A system, so I'd keep the C2's in the new rig.

So according to this TWINX1024-3200C2 memory he's saying is better then Value Ram.

Thanks

The point of getting value ram over high performance RAM is saving money. The 3-5% performance difference isn't worth the price premium of performance RAM. It's better to save the money and put it towards something else, like a better video card

don't know why this was removed from sticky, best A64 ram thread ever, Zebo has saved lots of us lots of money!!!!!

Yea, im sure it is. But it also costs more. You will get a performance increase, ever so slight one, over value ram because of the tighter timings. If you have the same overclock cpu speed, but your RAM is 1:1 with the cpu (lets say 300 "fsb" and 300 RAM) then you will also get a performance increase since your RAM is now going faster as well.

What are dividers?

Ok here is the price of Valueram, $82.99
http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=80098-21&ps=ho1

Corsair TWINX1024-3200C2, $99.99
http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=80097-16

This isn't what I would call a HUGE waste of money, if the extra $17 is going to help a little.

THANKS

Bah, you can find the Corsair VS (512MBx2) kit for $75 shipped if you take 5 minutes to check a price engine. You could also buy it used. I am a big fan of ValueRAM after overclocking my rig all to hell and not getting bottlenecked at the RAM, like I thought I would (turns out the stepping on the processor is E6, not E3, so it doesn't get to 2.7GHz with the retail HSF like I wanted). Go for the ValueRAM.

The second one is 2-3-3 instead of the 2.5-3-3 on the value memory, so the differences will be even much less than with 2-2-2 or 300mhz memory. Some of the Corsair VS sticks can do 2-3-3 easily anyway with a slight underclock. I have mine at 2-3-2 at 185mhz.

You can occasionally find a good deal on the high end memory, but in most cases I don't see why it's worth paying extra for even if you're overclocking the processor.

 

[DasFox]

I live in Hawaii BOLt, so that is why I showed ZipZoomFly, only $10 for any order size.

I thought there was more to XMS over Value Ram besides just CAS.

ALOHA

 

[DasFox]

Between (Value Ram)VS1GBKIT400 1GB Kit DDR400 PC3200 CAS2.5 and TWINX1024-3200C2 are there any other differences in the ram besides the CAS?

What else seperates XMS from Value Ram?

THANKS

 

[CP5670]

I don't think there is any other difference between these two packs aside from the heatspreaders (which don't do much). There are a couple different types of XMS though, some of which have better timings and/or higher bandwidth (and cost considerably more).

 

[nerp]

Yeah, well, I still would rather have my memory run at 250 Mhz if I've overclocked my FSB from 200 to 250 Mhz. . . I have begun to judge high performance memory more on their flexibility and stability under extreme conditions than on such trivial things as cas latency and Tras settings. The truth is having performance memory makes overclocking easier and gives you more options. This is why I spent my money. No matter what, lower latencies WILL give you some increase in speed, however small it might be under varying conditions. Memory has gotten a bit cheaper recently, too, so someone buying a $100 stick might find it a deal when it was $200 only a year ago.

I always thought PQI Turbo Memory is the fastest memory but it is not. Oh well. I think I set it at 2.5.3.3.2
