i am building a new computer, with fx55 and i am confused about memory oc'ing. i have built tow computers before but always stock, i wanted to go all out and get a high performance machine. I was looking at OCZ. My querstion is when you oc is it better to get ddr400 and raise it or get ddr500 that is already raised? what are the benefits of this, also mainly for gaming is it better to use 1gb or 2gb. Also has there benn a fix with amd and using 4 sticks without it dropping to 333mhz?

overclocking your ram doesn't normally give you much benefit with an a64.

and it's not really a straight forward procedure.. i wrote up a long step by step process for someone else long ago, but i'm kinda short on time today, so this will have to wait.

for the ram itself, it kinda depends on the board. if you go with DFI, get twinmos SP, even if it doesn't look all that good at stock ;)
otherwise, some ram like OCZ pc3200EL rev2 would work quite well
 
The new AMD 64 cores venice and san diego do indeed fix the ram bug. I had 2 sticks of corsair xms pc4400 tccd and 2 sticks of OCZ PC4400 bh5 all work fine even at 250 fsb. It had to be run at 2T though for it to work, but thats still DDR 500. The older models would only show 1.5gb of ram where the new cores show the full 2gb. The TCCD ram seems to work really well on the AMD64 CPU's as well. I personally get the higher speed memory so that I know it's garunteed to run at atleast DDR 550, then the only thing that I have to figure out is the timings to get it there, and what the CPU can handle. Good luck

Mr. Memory Expert :p,

So apparently each mother has a favorite son? There should be a sticky list of RAM model/brands that each motherboard manufacturers have the most success with. I'm getting the DFI LanParty SLI-based pretty soon. I was opting to go for Mushkin or Corsair. TwinMos works on par or better in this case?

And what happened to the negibility of RAM overclocking lately? IIRC, overclocking RAM was such a big thing for the Athlon XP's. Or maybe I'm just forgetting the fact it has to do with the onboard memory that the A64's have which easily reduces the dependancy on memory sticks.

I am not sure why eclipse is saying its not as big of a deal. I notice large improvements overclocking the ram. Maybe he means that oveclocking the CPU will get you more then OCing the ram, but I personally like to OC the crap out of both to their max stable limits. Doing just 1 or the other doesn't seem like it would be as efficient, either the CPU cant get data from the memory fast enough, or the memory cant get data to the CPU fast enough. It has to work well on both ends for it to run smoothly. Maybe you could enlighten both of us on this eclipse!

hehe, indeed. my personal choice is micron, but in some cases, it's not the best. this would be one. wherever you have access to at least 3.3v Vdimm, the CH-5/UTT ram is a better choice for oc'ing, as you can typically do more mhz with lower timings, which is always a good thing. dfi + twinmos sp = awesomeness

yeah, it's because of that onboard memory controller and the slightly tweaked architecture. a64 just isn't bandwidth starved like it's older brother is, and nothing like the netburst based intels :eek:
even so, there's one thing oc'ig really helps with. benching.
if you're an OCD overclocker/tweaker like me, you'll overclock for the fun of it, not for the actual benefit :D

also, that pc5000 ocz is a complete and utter waste of money :eek:

that's pretty hot for an sli setup. just one video card for now?
(edit, just did the math, total looks like it's for 2x6800gt's)

</ot>
 
Really? I'd die for 2x6800GT's at that price. It's actually just one. The second 6800GT will be bought later on. :D

venice and sandiego are not fx chips though are they? In any ones experience do you get better performance starting with stock and moving up or buying higher ddr level and oc timing?
