timings are 2-2-2-6. 2.8v

i dont know much about timings and stuff so if someone could please explain a little it would help.

is this pretty good quality?

suprasteve

well I don't know a ton about memory either, but I do know that 2-2-2-6 timings are really fast, and as far as I've heard, crucial is decent. Just to avoid the stupid mistakes, I take it the memory is not for the notebook in your sig right?

jancz3rt

Yeah the timings are very fast and the brand is good as well. If you do buy that RAM, you will not regret it. I would personally go cheaper, but that's just me.

*in a crappy british accent* right-o.

ok, lets see here. i think it is a really good deal. lets crunch some numbers shall we.

My RAM:$55.00

2 x $55.00=$110

Same RAM just comes in 2 x 512MB:
$119.00

so i am thinking about ordering two sticks of the 512 instead of the 2 x 512 combo because i will save a few bucks. and i dont think that it is pricey because i have looked at corsair xms with timings of 2-3-3-6 for more.

thanks for the help though guys. i am just gonna go with the 512 crucial ballistix for now, and when my b-day rolls around in a few months(march) i am gonna get another stick. im trying to keep my "budget gamer" actually within my budget. lol

if anyone wants to know what i am getting i will be glad to let you guys know so you could make suggestions. just pm. dont worry it will be in my sig soon enough.

The voltage required to get those timing is on the high side but its not bad, generally you'll want the lowest timings with the lowest voltage

Consider this for instance

is .3V more really that bad? what are some drawbacks of higher voltage ram with better timings? my guess would be heat issues, but i really dont know.


seems pretty good(ill definitely consider it, given the low price delta), but what does the "T1" mean?

Praetor

Well 0.3v is a lot for vDimm considering the spec calls for 2.5-2.6 and active cooling is "strongly reccomended" (and required for warranties) at 3.1v+

Command Rate = 1 clock

i have a question for ya praetor......i was looking up ram on newegg by voltage and i noticed that it was kinda weird.

i was wondering how come this ram is 1.85v with a heatspreader and this ram is 3.3v without a heatspreader? does it have something to do with the speed?

btw i bought the ram that you suggested for me since the ram i wanted went up a few dollars and the price difference was only $2.45. thanks for the help.

Praetor

Heatspreading and by-SPD voltage dont have all that much to do with each other. In more detail:

- PC133 uses 3.3volts but since the clocks are low etc (old memory technology) it doesnt get hot
- DDR uses 2.5/2.6 volts. What this means is that manufacturers should report DDR400 memory (DDR400 chosen at random doesnt matter) the timings of the RAM at that voltage. So that means what you should be seeing is "<Company> <Series> <Model> - <Speed Rating> with timings of <timings as given at 2.5/2.6v" or something to that effect

So, for a realworld example, we have (taken from this memory),
Company = Patriot Memory
Series = Extreme Performance
Model # = PEP5123200LL
Speed Rating = 200Mhz, DDR400, PC3200 whatever
Timings = 2-3-2-5-T1 (very nice that they tell us it can do those timing at command rate T1)
Voltage = 2.5V

Now consider the very popular, memory,
Company = Corsair Micro
Series = XMS
Model# = CMX512-3200XLPRO
Speed Rating = 200Mhz, DDR400, PC3200 whatever
Timings = 2-2-2-5 (we can hope that Corsair means this will run 1T but no 'guarantee)
Voltage = 2.8V

Now between them which would I take? Id prolly take the former because I know:
- By increasing the voltage you can push the memory harder. This means that by increasing vDimm, i can either push the clock higher or tighten the timings more -- or both
- Now I know (from expereince and a bit of techie sense), that with 2.5v memory i could probably run the former at 2-2-2-5-1T although worst case scenario i can bump to 2.6v and still have a 0.2v advantage
- Why advantage? The lower the voltage the lower tthe heat, the less stress yer putting on your modules and the more voltage you can add before you hit that 2.9v boundary (after 2,8v, you're on yer own) so that means i could possibly run the former at DDR466 with the same timings at 2.85V ... not so sure about the latter

wow! thanks for the in-depth explination.

so basically you are saying the by upping the voltage on the one with a lower voltage and slightly slower times, that it could run better/faster than the stick with higher voltage and better times? and at the same time, run at a lower voltage than the latter, which means less heat? i think i got it all. confusing lol.

thanks for all the help praetor

i have one more question........if i get ddr 400 ram, will it only run at 266 if that is the fsb of my mobo?
