Corsair TWINX1024-4400C25PT 1GB Kit DDR550 $269

Here is the review

$269 @ zip zoom fly

For all of you out there with 3000+ 90nm AMD 64s on socket 939 mobos... this is absolutely the best memory you can own if you plan on overclocking

Thanks for the link!

To expensive for me

I have Patriot XBL from Newegg. It is TCCD and defaults to 2-2-2-5 on my Neo2 Plat for $219ish. I have not had time to OC it yet, but it works very well. The plain Mushkin for $137 a gig ain't too shabby either at default 2.5-3-3-7.

The Corsair memory is 6% faster than this Geil memory at overclocked speeds

difference

if you aren't planning on overclocking than use this stuff:

Exactly how much does memory affect OC'ing an AMD64 3000+ 939? I am going to purchasing that in the next month and I currently have 2x512MB Crucial PC3200 DDR. How much is my memory going to hold me back in OC'ing that CPU?

You can always use memory divider if your memory is not that good like mine (Corsair Value Select PC3200).

 

[salsa086]

fxsts is absolutely right. Most motherboards allow an asynchronous operation mode allowing you to overclock your processor independent of the memory system.

However the massive overclocking performance boosts are achieved when you leave the CPU and memory synchronized and don't modify the multiplier and crank up the FSB speed.

The asynchronous overclock is basically a "poor man's" overclock.. it definately works.. but not as well as an overclock involving your FSB. The value ram stuff limits your overclocking potential significantly. Not to mention some CPUs are multiplier locked and thus can only be OC'ed via FSB changes.

example: two system running at 2000mhz

system 1 has the following setting... 10 x 200fsb

system 2 has the following setting 8 x 250fsb

the resulting processor speed is the same... but system 2 will be faster...

also make sure your tRas is set to 10.. it yields the best performance on an AMD64 system (at least as reported by anandtech and hardocp)

I was under the impression that all A64's outside of the FX CPU's are multiplier locked. If that is true, then would I only be able to OC via FSB a 3000+ 939? And if that's true, then I'm hardly going to be able to do anything with it with my standard PC3200 right? Or are you saying that you can adjust FSB independently of RAM speed?

 

[PClark99]

Actually, you can downclock the multipliers on the A64 non-FX chips.

ie. My 3500+ runs 200x11 by default. I run it at 250x10.

There are different RAM multipliers so you can downclock the RAM also.

 

[Solema]

I see. So the RAM has a ratio like NForce2 boards? An FSB-to-DRAM ratio? Currently I have an AMD XP 1700+ set to 2600+ via raising the multiplier and FSB and leaving the RAM at 400. Since I won't be able to actually RAISE the multiplier with a 3000+ A64, how much OC'ing can I actually do with it, theoretically, presuming I leave the DRAM at 400?
