What is the downside of running RAM that's timing is 8-8-8-21 at 9-9-9-24 or something other than what it's supposed to be? This something I've always been curious about and I'd like to hear from people with real world experience.

Syracuse, NY | LOL, I've always wondered if it hurt anything. I usually change my timings before I even fire up a new build for the first time.

| I always leave the RAM timings in the BIOS set to "By SPD"...
The only parameter that I usually double-check/adjust for in the BIOS (if necessary), is the RAM's Voltage, just to make sure that it agrees with the particular RAM Manufacturer's Spec Sheets.

You might want to also check the manufacturer specifications on the timings too. Some manufacturers (like OCZ) will set the SPD of faster RAM to slower speeds than the RAM is spec'd at to make them more compatible with cheaper motherboards that can not handle the faster timings.
The CAS is mainly effected by this and often CAS-2 rated RAM will have an SPD of CAS-2.5 or even 3 and you have to manually set it to 2 to get the full performance out of it. |

Real world has two sides, one is basic plug & play and the other is OC. This is another question many people ask, essentially if you follow the requirements for a given mobo/chipset timing won't really matter. It's only when you want to scathe the last nanometer of bandwidth from a DDR chip, that it does matter.
What is it you really want to know? How fast a given memory chip will work, or how hard you can push it? Timing is relative to to a chipset and BIOS, sometimes only a chipset based timing will work, given a mobo manufacturer won't make BIOS changes that will extend past normal and accepted results. |

That's a LOT of different ram types the mobo can handle. Which ram spec has the best price vs performance ratio? |

1 edit | 4GB of performance ram for just over a 100 is hard to beat
go faster and price goes up to much
go slower and price really doesnt drop much for good name brands i would trust

Cool and thanks. Would there be a minimum latency that I should get? |

like 9-9-9-something
what i linked is CAS 8
its great ram 1600 and CAS 8 for 110 |

I read a comment the other day that the RAM specs mean very little and 800 or 1066 is fine unless you're overclocking....now, I'm confused. |
