will corsair vengeance DDR3 10-10-10-27 work on 78LGM-USB3 mobo?

[pcquotes2]

hello follow geek;

I just got a 16 gig RAM kit. the model of the RAM is Corsair Vengeance DDR3 1600 MHz.

first. my mobo are able to support the DDR3 1660 mhz RAM but if I go into the bios and set it to auto, the RAM will run at the alloed maxium speed.

in other word, the RAM will run at 1333 instead of 1600.

the main reason for asking this question is should I exchange for the kit from the same company with the CAS of 9-9-9-24 or will the 10-10-10-27 is fine?

any advice is greatly appreciated.

It's fine.

 

[pcquotes2]

It's fine.

i need a little more.

by saying it fine does not reassure anything.

since the RAM CAS is at 10-10-10-27, and I send it to auto; does that mean the RAM run at 1600 MHz at all time or will it decrease the speed of the RAM to 1333 mhz.

again, by saying it fine does not make me satisfy. i need a little more explanation on wither it should swap out the kit for another kit?

CAS10 and CAS9 timings for 1333MT/s OR 1600MT/s are so mediocre and loose that it isn't going to make a gnat's ass of a difference.

Is that more assuring?

Easiest way to make sure is this:

Go into your bios, find the memory settings, and manually set the speed to 1600mhz. The memory is rated at 1600mhz cas 10, so take the guesswork out of it. Sometimes in Auto mode, it might just default to the slower speed (I had a MOBO that did this - 1600mhz RAM and on auto it would default to 1333).

So - set it manually and you should be good. The timings should be correctly determined, just manually set the MHZ.

As for switching for the cas 9 vs the cas 10, you'd pick up a bit of speed, but not enough to justify a whole new kit. If you were making a serious jump (ie going to 1866/2133 mhz) I always suggest getting the lowest mhz/cas ratio that is reasonably affordable and as you get up in the mhz, the cas becomes progressively more important.

While the difference between cas 9 and cas 10 at 1033/1333 speeds is 10% or so, the difference between cas 9 and 10 at near 2ghz speeds becomes far more significant (20%)

nope.

let me make it simple. how to set the RAM run at the max speed of 1333 mhz instead of 1600 mhz in the mobo bios.

since I already set the DRAM to auto.

your response does not seem to answer anything. just the use the word ass.

so what you are saying.

if want the RAM to run at max speed, I should go in the bios and set the CAS to 9?

if i leave it at auto, will that decrease the CAS on it own or will just run at 1600 mhz speed on it own?

thank. your response is more clear than the person the previous response.

Hi, no, you can't set the cas to 9.

The listings on your ram module itself are in general the maximum that it will run at -reliably- and at spec. That means the max speed you should run the RAM at is 1600mhz @ cas 10 since that's what it's rated at. If it could be run faster at faster (lower) cas settings, they would label it as such since they can charge more for it...

So - go into the bios, find the ram multipliers or just set the speed in MHZ so it's at 1600mhz - that really depends on the exact board and bios. The bios should autodetect the proper CAS - but either way it should be cas 10 - again, because that's what it's rated for.

That way you're getting what you paid for... Hope that helps.

So if i understand you correctly, if i set the bios to Auto, the mobo bios will determine the correct and stable speed for me without having me to do any guess work, right?

 

[damric]

In AUTO, the motherboard will default to JEDEC specification or the SPD tables in the PROM.

Generally, yes. It might not get the -fastest- speed, like I said, I had some issues with a Gigabyte board which would 'auto' to 1333 cas 9 on some modules I had which were 1600 cas 9. But all I did is go into the bios, change the 1333 to 1600 manually, and I was good to go at 1600.

Remember, it's a combination of what your motherboard can handle -and- your memory sticks can handle when you're looking for getting the performance is capable of. Sometimes you might have to change some settings manually.

If I leave it set at auto, will i run into probmem in the future?

You will have no problems with Auto setting. It might not be the -ideal- setting, but it -will- work just fine.
