memory for an AMD64?

thinking about goign to a high end amd64... reading anandtechs reviews on value RAM but started thinking about RAM bottlenecks...

what kind of RAM should i get for high end amd64? i mean, is there a type of RAM that i shouldnt go lower than because itll start hurting the performance of the amd64? i was thinking about getting a couple gigs of value ram (like OCZ or something) since ive never been into the whole overclocking thing, but if its going to make a huge impact on my system, i might as well bite the bullet and get something better.

any advice? thanks
 
With an A64, you can get valueram and take almost no performance hit. If you must have the absolute best, get ram that has 2-2-2 timings.
 
Yeah,... well, everyone says to get value ram cause there is almost no performance hit. About 5% -8% give or take a little. Personally I'll spend an extra $20 - $40,... why? First off, $40 is really not that much, second,... good RAM will outlast the rest of your machine,.... I mean where is that MB and 800mhz cpu you bought 3 years ago? The mem I bought years ago worked great in a sktA, a 754, and a 939, and third I like to run 1:1, 1T, 2,3,3,6 at 270 htt or better and <2.8v but thats just me ;-)
 
Ok,...rant off hahahahh,.....
Anyway what about the rest of your system? A little more info and I'd bet someone here could help you out with a suggestion for the best mem for your system. ie: if you have a DFI LP UT NF4 SLI-DR you'll want different memory than if you have an MSI K7N2G.
 
but in three years, amd and intel will probably only have ddr on their value cpu's, value ram has timings around 2.5-3-3-8 ususally, its about 3-4% going to 2-2-2-6, get a better cpu, mobo or gpu
 
No point buy premium RAM - not now or even if it was to be used in a latter rig. Anhow, AMD is moving to DDR2 in 2006 with M2 and then a year later to DDR3.

As before just get Crucial Value 1GB sticks - they're speed binned Ballistix and overclock exceptionally well - crank it up to 2.8V and you should be happily hitting DDR480-500 at CAS 3.

Moreover, when you go dual-core they'll no doubt benefit from the extra bandwidth ie being 1T and running upto 250mhz.

Nice!!! Can you run 200 2-2-2? I could run 2-2-2 with 2x 512 @ 200 with crucial value. Same stuff as ballistix but not speed binned.

PS you will find that a bit faster too dispite less bandwidth... Use 166 mem setting. divider has no effect on k8 systems
 
What does "speed binned" mean? Someone advised that I should get Crucial Value because it's "speed binned" Ballistix. Does that mean it has a speed cap? An upper limit of some sort?
 
Naw it means they put a whole bunch of memory IC's (the little chips you see on your memory sticks) though speed tests at default voltage. ones that pass low latency and high bandwidth get separated and stuck onto high end ballistix ram.. The rest are set aside for value sticks.

Now there are two conditions you can get "lucky" and get ballistix for half price.

1) what if yeild are good that week and all or most IC's are are capable of latency and high bandwidth. You get great stuff on cheap ram because theyll use them anyway on budget sticks.

2) Sometimes additional voltage can overcome less good chips to make them run just like the speed bin stuff did at default voltage.
 
So it's like gambling...in which case you could get stuck with what you paid for, huh? How reliable is the voltage increase method? Because if it works more than 60-70% of the time, Crucial is gonna figure out, and try to do something about it.
 
Yea it's gambleing like any overclcoking is.. and voids warranty.

The Ballistix is guarnteed to run 2-2-2@200 with 2.6 volts for life.. It's it worth twice the price? I dunno personel choice. Percentage sucess? I dunno either because ram is not talked about so much like processors and thier is so much more ram companies making sample size of any particular module very small to come up with anything concrete.

Because if it works more than 60-70% of the time, Crucial is gonna figure out, and try to do something about it.

Nah they don't care. AMD knows all or most thier chips can hit 2.4, they hav'nt done nothing to the cheap ones like 1.8's 2.0's etc.. Overclcokers is insignifigant market really. Most people buy stock and run stock. Especially true with crucial who is #1 OEM provider of ram.

best i got was 257mhz at 2.5-3-3-8 and 2-3-2-7 @225ish. i think 250x11 will be my best bet?

:thumbsup:
Can you take a pic of IC's on chips? Or post what they say?

Easy way to tell fastest is run winrar's internal bench, highest wins and it's the most demonstrative program to tell. Should be real close but I think "2-3-2-7 @225ish" may be a little quicker assuming same processor speed of course..
 
i will but is there any trick to taking off the spreaders? from what i've gathered its an infineon be-5 chip same thing ocz uses in their titanium 1 gig sticks and patriot too.

i would liike to take them off and see what the hell they are because they seem to clock twice as well as any other infineon i've seen in a review or forum post. i just don't want to screw them up.

Value ram with heat spreaders? wow.

Anyway I would'nt since it voids warranty.. some guys say it's better to take them off though since heat spreaders really are heat containers.

Makes sense, doesn't it? They're meant to spread the heat, not dissapate it. So it just sits on the spreader, unless you have a fan blowing across it, in which case you really don't need a heatspreader anyway.
 
yeah, the warranty thing concerns me but not as much as never having done it. hell whats another voided warranty 😛 i guess the trick is to make sure they're uber clean/dust free before putting them back on?

anyway, i'm just more surous as anything.

as far as the value, i guess this is part of mushkins new order with this called hi performance, middle of the road. i've never used mushkie before much lighter spreader than ocz uses. still at 2.75v in bios or 2.82v on a dmm.
 
11427,

itll probaly be a high end amd64, most likely fx55. mobo, i am not sure yet, MSI Neo4 with a 6600GT vid... OR i might just get a board that still has AGP on it. I have a ATI 9800 pro that i am happy with and i dont see myself playing too many games in the next 2 years so i might rather just save the ~170$ on a new vid card.
 
On an Athlon 64, ram timings mean nothing performance wise. Only get expensive ram if you are going to be overclocking and need the head room.

With an Athlon 64 pc, you want to be sure you have a quality motherboard and powersupply. Those two right there are the biggest causes of problems when building a new pc.
