In a Athlon64 system running at standard speeds, is there a big performance improvement using 2-2-2-5 memory over 2.5-3-3-7 memory?

What about when overclocking? What is the performance improvement, percentage wise?

only in benchmarks would you see a differences, not in real life apps (maybe WINRAR, but thats it)

Minimal.

Tightest timings vs. loosest timings is about a 5% difference.


Better off buying more of the looser timings than less of the tighter.

All I know is that I used to buy the LL expensive stuff and recently switched to Value Select; I can't tell a difference at all. Your wallet sure can feel the difference though.

There's no perceivable difference. I had an Athlon XP 1900+ with 2x512 MB of PC2100 at 2.5-3-3-7 in one of my computers. My girlfriend only had 512 MBs in her computer, and The Sims 2 ate up every last byte of that, so I swapped her 2x256MB of PC3000 2-2-2-5 RAM with my slower set of 2x512 MB. Now my 1900+ feels the same in Windows, but MUCH slower when loading and exiting games, while her computer is much snappier than before.

According to benchmarks, 2.5-3-3-7 is about 7% slower than 2-2-2-5 in 3DMark 2001 SE. I can't see the difference.

One doesn't generally opt for the lowest latency memory for the neglible performance gain on its own but for the higher clock potential. The 2-2-2-5 part will prolly clock much higher at 2.5-3-3-7 or such than the 2.5-3-3-7 part, allowing for very significant performance increase from a higher FSB (CPU o'erclock). In such case the memory bandwidth may or may not actually increase.

For the premium they charge on those LL sticks, I'm surprised anyone buys it. Its just not enough better to in any way justify the cost. Maybe if you're overclocking like has been said.

Hmm. Well im not too familiar with internet options so i cant help you there. However, the link goes to the CPU/OCing forum and at the top the A64 Memory Matrix thread. That should help in your decision.

Go into your Profile then Personal Options and make sure you don't have the CPU/Processors and Overclocking Forum blocked.

:eek:

I wonder why it blocks me out completely. I just wanted to thin out my list, not censor myself... :p
