memory OC'ing

[DrCrap]

and one more question, when you write that you have memory settings at 2.5-4-3-7 1 T then what exactly does it mean? (I figure the 2.5 is for latency, but what's the rest, and how do I set it in the bios?)

anyone...?

It's just the timings of various latency settings in memory. These vary depending on the memory you use and the processor. So it's best to look around for people with your setup and try the memory settings.

SPD is serial prescence detect - RAM has a chip on it that tells bios normal running config of RAM
In other words - autopilot

www.Lostcircuits.com has lots of articles on RAM timings - latencies

Leave it alone, If it aint broke don't fix it. In other words if you don't know what you are doing then don't mess with it.

IMHO one of the major reasons people come to this forum is to learn, giving advices like this is very unhelpfull, not to mention annoyance. I have a better suggestion for you, if you don't know what you're talking about, don't answer, if you do then be kind and explain, or otherwise reffer to related articles, but don't kill threads with your lameness.

First is indeed CAS latency, which is the most important of all settings (the lower the better)
Last is not so important, AMD systems like it high , say 10 or 11, Intel likes it low, say 5 or 6...number has something to do with correcting inbalances in your memory or something

Numbers in the middle are "Row Precharge Time" and "Read To Write Delay"

the lower the better...

If u are going to buy memory, keep in mind that the higher the memory speed (400mhz, 500mhz, or PC3200, PC4000), the "looser" the timings HAVE to be...

Anything over PC3200 memory (400mhz) is for overclocking, so look at the timings when u are going to purchase memory ... I didnt and my timings SUCK... 3-4-4-8

Luckily the memory has no problems running at 2.5-3-3-10...Still not awesome but better

Memory timings are especially important with AMD systems, although you might not notice any difference when u do "usual" things with your computer (meaning not gaming, clocking, or benching)

DDR2 memory is just fast memory (high FSB speeds need fast memory) with sh*tty timings,

1t or 2t command rate > 2T command rate is slower, especially on AMD systems its a real performance killer...However when u have more then two memory banks in your Motherboard, 2t command is needed

Be carefull with setting those timings...:

T command rate should be available in your BIOS, memory timings may not be...

If you have an AMD system, u could download the "A64 Tweaker" < google it or something..
Be sure you DONT set that your settings are enabled at bootup!!!Otherwise when u get a black screen, which u probably will get a few times messing with the memory timings, u dont have to switch jumpers on your mobo, or pull out the batteries...U can then simply power down and reboot..

Do some reading first before screwing with those timings
