Read this before using 4 512 sticks of RAM.

If you use the Athlon 64. Do not run 4 512 sticks of DIMM, it will resort to 2T timings and it could possibly glitch up and run at 333 MHz.

I see a lot of threads were people have issues with 512 sticks of memory, DONT DO IT. Save yourself a hassle and buy 2X1 GB sticks. Some people claim the differents is noticeable and some claim its not, either way for the sake of overclocking.

Cobbler made an interesting point.

4x512MB single-sided RAM= DDR400,@2T
4x512MB double-sided RAM=DDR333, @2T
2x512MB double or single=DDR400, @1T

If this info is not right, someone PM me.

I took these on my rig which consists of the following specs.

Athlon 64 Venice 3200+ @ 2.6 GHz
MSI K8N Neo2
Radeon 9800 Pro 128
512X2 Corsair Value Select, Dual Channel PC3200 @ 433 MHz.
WD Raptor 36
Maxtor DMP 9 80 GB SATA HDD



 
Thank you for the PSA of common enthusiast knowledge.

This has more to do with the A64 CPU itself than the chipset the motherboard uses, as the memory controller is on-die for the K8 line.
 
Ahem... as someone who is getting ready to plunk down his monies for RAM and a new mobo, what is the desired config to reach 2G of memory? Two 1G sticks?
 
Do the x2 cpu's have this same problem? Here in Australia the 1gb sticks are overpriced 🙁

I have an Asus A8N Premium motherboard.

yes, two 1gb sticks.

only matters whether RAM is single or double-sided

i.e. double-sided RAM 4x512 on Venice=still DDR333

1T generally gives between 0.3% and 2% performance boost. Some people have seen up to 4% in certain games. Really no biggie.

I beg to differ:

300x9=2700mhz
150 divider=225mhz RAM@ 2.5,3,3,6 2T
results:
memtest86+= 2454mb/s
Sandra= 5446/5443
SuperPi 1M= 33.641s
PCMark05= 4022

300x9=2700mhz
140divider=210mhz RAM@ 2.5,3,3,6 1T
results:
memtest86+= 2511mb/s
Sandra= 6141/6167
SuperPi 1M= 33.140s
PCMark05= 4067

so the difference is quite a bit more than 25mhz RAM speed to say the least
much better performance at lower RAM speed and 1T vs. 2T at next divider up

I run 4 x 512 double sided @ 400, 2t on my x2.

Read the thread. Actual benchmarks don't show a noticeable difference. Sandra and Memtest aren't useful apps. Even in SuperPI, which does like fast memory, you can see for yourself that the difference is insignificant.

Let this be a lesson to you: do your research before posting. Sorry if I was harsh, but you're spreading FUD, and if other people took your advice they could end up losing money.

because I argued the point that 1T appears faster than 2T?

why don't you learn to just be a little respectful, rather than an arrogant prick?

I believe fresh is refering to the statement,"doesn't matter Winchester or Venice, etc.

i.e. double-sided RAM 4x512 on Venice=still DDR333"

This is false info!

so with Venice it doesn't matter whether sticks are double-sided? I used to think that was the case, then was ripped apart by another poster claiming that the Venice and Winchester memory controllers are identical? what changed?

thnks

The memory controller on the Venice is improved, so it can run at DDR400 with 4 double-sided sticks.

Yes. Someone listen to what you say and blow a ton of money on dual 1GB sticks when they can spend a lot less and add two more to the 2x512 they already have. I know you have your ego, but I don't think that sacrificing other people's pocketbooks to it is right! Sacrifice your own all you want to, but if we post stuff here:

1) Make sure you are correct first
2) If you think you are correct but don't know for sure, say so
3) If you don't know, say you don't know, or keep quiet
4) If what you think you know is not first-hand, tell us where you heard it

There's an awful lot of BS going around in this hobby and you were contributing to it. That's all.

Sorry, but I actually think that "Owned" is more respectful than either "14-year-old numbnuts" or "arrogant prick." As I already apologised to you, I think it's you who is out of order here.

That wasn't me, mate. Here's what I said:

I run 4x512MB at DDR400 2T. Venice core.

all valid points, but "owned" is about as far from respectful as you can get. that's a word that certain groups of people don't take very kindly to.
maybe you should rethink the use of that word, and what it implies.
 
btw, sorry for the disinformation (I was wrong)
I am not ego-driven, just thought I was helping

name-calling was out of line, but in fairness, use a little tact in the future
