Hi all, well, I already know the answer to my question, YES! It is my stubborn friend who wont believe me cause I am 2 years younger then him. He is convinced that you should buy whatever is cheepest when it comes to RAM, that Corsair XMS, OCZ, GeiL, and all of that, is a complete waste of money. Plz, explain why High end RAM is better, SO I CAN SHOW HIM THAT AGE DOESN'T COUNT FOR NOTHING!

Agreed, people that use their opposition's age to win an argument are shallow.

Ram with a higher rating is faster in most cases. However, if you use a, say, pc3200 with a pc2700 than the pc 3200 will become bottlenecked and will run at pc2700 speeds.

No, I mean, he thinks there is no difference between ddr400 Corsair ram, and ddr400 Corsair XMS series ram, Kingston and kingston hyper X, ect...

If all you're doing is throwing RAM into a box and turning it on... then there really isn't much of a difference to speak of between, say, two different sets of PC3200. Any real difference will boil down to differences in timings and (possibly) SPD programmings, and you aren't likely to pick up on them if you aren't benchmarking, particularly on an Athlon64.

Now, when it comes to overclocking the story is a little different. When I was doing it incessantly, OCZ was well known for excellent SPD programming and PCB designs: you could often squeeze a couple more MHz out of their products where other brands would falter (even with the same chips). Realistically, however, the ICs used on the modules have a more substantial impact than anything else. On that note, I've heard of Kingston ValueRAM showing up with Winbond BH5 chips (for those that don't know, BH5 used to be the chip for overclocking memory: it would run up to maybe 235MHz at 2-2-2-5 with huge amounts of voltage. Samsung's TCCD and TCC5 usurped that crown, though).

So then, where'm I going with all this? You're both right. For bumming around on the Internet, checking email and stepping on mines, one set of sticks is as good as the next. For overclocking, benchmarking, or otherwise forcing that last per cent of performance out of your rig, then yes. There's a difference, and depending on what you compare, a very big one.

so if i have a stick of 2700 ram and a stik of 3200, there both gonna run at 2700? And is that bad or anything?

Correct,but there is only a negligable difference. The 2700 and 3200 are series, produced by a certain company. Kind of like Windows 95, 98, and 2000; except those are series of OS's, not RAM sticks. The difference is how easily is corresponds and reacts to the stuff your PC's processor throws at it. But as for it being *bad*, no. As C38 said, most of us don't come near to taxing our RAM in everyday things. A difference in series is almost unnoticeable unless you are overclocking your PC.

but what if the ram is from different companies. For me my original ram was some samsung 2700 and my new one is a patriot 3200. Actually my new one looks rweally nice :) , but should i get another stick of 512 ram to replace the old samsung one?

Hmmmm, I don't know about different companies. I would be inclined to think most types of RAM, from whichever company, will be compatible with others. Especially the larger brands. Generic, unnamed brands might not...

Ram with a higher rating is faster in most cases. However, if you use a, say, pc3200 with a pc2700 than the pc 3200 will become bottlenecked and will run at pc2700 speeds.

exactly.

PC3200 - 333megahertz PC3400 - 400megahertz PC3500 - 433megahertz

those are the speeds i know off the top of my head, the speeds arent like a processor so dont think there slow, thats plenty fast enough for high speed ram. the max for your processor is only a certian PC mark. my max is PC3200, i can OC it manually, which i do, but currently its running at PC3200 instead at its stock mark, my ram is PC3500. if i upgrade my rig to a better processor the speed of my ram will keep up with it, going to 3400 or 3500 depending on what i get. so its very important when you buy new ram to get the highest PCmark you can find. PC3700 would run in my machine, but only at the speed of 3200. its a good way of future profing it. also, CHEAP memory usually has shitty stock memory timmings. most good ram like my samsung ram and corsair ram run at 2-2-2-5 right out of the box. your freind is a big noob. LAWL!!

1337cshackerexactly. PC3200 - 333megahertz PC3400 - 400megahertz PC3500 - 433megahertz

your freind is a big noob. LAWL!!

You're appearantly a "big noob" also. By default: PC1600 clocks at 100MHz for an effective data rate of 200MHz. PC2100 clocks at 133MHz for an effective data rate of 266MHz. PC2700 clocks at 166MHz for an effective data rate of 333MHz PC3200 clocks at 200MHz for an effective data rate of 400MHz. PC3500 clocks at 216MHz for an effective data rate of 433MHz. PC3700 clocks at 233MHz for an effective data rate of 466MHz. PC4000 clocks at 250MHz for an effective data rate of 500MHz. PC4200 clocks at 266MHz for an effective data rate of 533MHz. That's the standard set of DDR speeds. DDR2 has some oddball slower speeds (PC2-3400 and PC2-3600 IIRC), but we're not talking about DDR2, and PC2-3200 still clocks at 400MHz. @dank~ If you're using a Pentium4, then yes you should match the sticks. That's not absolutely necessary (it's sufficient to just match the ICs, capacity and sidedness), but P4s really benefit from dual channel, and matched sticks are the best way to ensure this.
