ddr800 4-4-4-12 400fsb 1:1 2800mhz


ddr1000 5-5-5-15 400fsb 4:5 2800mhz


ddr1000 5-5-5-15 400fsb 4:5 2800mhz (2# attempt)


why all the difference so small?

i want to know more on trd/performance level.
i knows nothing bout it, only know it affects nb performance (somewhat nb latencies?)
so i went on reading more bout it but still blur on it.

somewhat get to know... it related to fsb, strap, vmch, vdimm, ram ratio, trfc...
why it related to so many things?

isn't that bios/memset can manually set it?
isn't that, just trial and error it.. to get the lowest trd stable?
why need to see fsb strap, vmch, vdimm, ram ratio, trfc?

-

& does it affects much on normal oc?
i mean, 1st thing is go for max cpu clock, then max ram clock & follows by tighten the timing right?
then when does this trd/performance level, comes into role?
can it be ignore on oc?

--

i tried 400fsb , 1:1 , 4-4-4-12 , trd manual set to 6 rather than auto. (i think auto=12 or 10)
the read, copy, latencies seems improved quite alot significantly.

---

lastly, i read cstkl posts.. he mentioned (or argue/bash/critics jkjk) quite frequent on this trd/performance level regrading others' oc profile,
so, i wanna know more. >_<

thnx.

hmm, cannot means it'll not stable ka?

btw, to test trd is by using those cpu stress test or memtest?
thnx.

here's wat i got from everest,
in bios, i set mem timing to 4-4-4-12 & trd=6.
other subtimings, all on auto.

tried 420fsb 4:5 trd=7 (or 6, if i got it wrong)...
can't boot though.

that's weird.

from the anandt,
counted the formula, 2>2 ? , should be = no.
which should results in either won't Post/operate.

heck, i ran stress test and folding straight till now.. seems no issue eh?

there u go,
btw, shouldn't be something to do w/ the multiplier right?
since i'm running 7x400 -> 2.8
not on native 8x.

whoa, does the difference in scores mean.. the performance gap of chipset between g33 & x48?

hmm, how to determine the strap ah?
afaik, dfi bios got options for manual selections on several straps in the menu eh?
i think i don't have it in my bios, and also dunno where the strap change for my mobo.

that geil f2-8000 (blue heatspreader), i remember it's actually ddr2 800 but rated as 1066..
it's a hot budget 4gb oc kit.. priced damn low yet some managed to get it over 1100mhz
but heard it's trfc need to be loose, while some board having issues with it due to default trfc too tight.

anyway, i'd love to see if ones actually-really-fully 100& utilize 1200mhz ram speed by 1:1 which is 600fsb.
didn't see any in here before, or did i missed out?

btw, bump in clocks w/ fsb stays.. the memory speed shouldn't be affected right?
there seems to be slight increase on memory speed as above, though fsb stay.

and, wat's DIMM Clock Fine Delay?
it seems to alter itself..
as previously i got 6T on blanks & 11T on occup.
while now 7T on blanks & one 11T one 12T on that 2 sticks.
why is that? somemore diff. on both dimms >_<

there's also debatable issue on consideration of 4 highly-oc'ed sticks cause burden on mobo.
either results in high-clocks unachievable or unstable.

so, end up 2x2gb setup seems more preferable but with very limited choices avail for nice oc-able kits.

as d9 ain't exists in 2gb sticks
somehow, nice oc-able 2gb stick's chip is still unknown?

oh no...
did u mean u won't feels any lag, when ram usage hit 99% ?
so, u think got a bad-ass gtx280 won't have any lag on 99% ram usage, due to the graphic card too powerful?

in general,
ppl go for 4gb when their ram usage frequently hit >90% when using 2gb.
ppl don't go for 4gb, for what u said "3% diff / +-5 FPS"

guys, u should try vista 1st before saying 1gb / 2 gb is enough.
even my lappy's on vista home, fresh boot to window.. already hoggs 1gb ram usage.
if i were to open another few apps. & play new titles game on it.
what makes u think 2gb is enough for gaming on vista?

yes, it's enough to play solitaire.. though

-

and yes, i agree 2gb is enough on winxp in general.
though mine goes over 2gb usage when running 2 smp folding, firefox, msn, online game.

*DO note that the usage that i'm implicating is with the virtual mem. turned to off.
as i want snappy performance on my daily alt-tab out tab in, etc.

just to add,

my desktop is running winxp,
"though mine goes over 2gb usage when running 2 smp folding, firefox, msn, online game."
that's for winxp.

on fresh boot to window, launch two smp client (p2665)
it'll be 1.4gb+ used.

if it's p2665 + p2653 , then it'll be 1.2gb
but nowadays.. almost everytime both gets p2665.

my current usage is 1.86gb
with 2x smp, firefox, ttplayer, fahmon, ..
others are background.. , those kapersky, fahremote, etc. etc.

ohh, please.
do say more, don't just put a "lol."

though i don't have the knowledge of how windows manage system memory,
but i do experienced 99% ram usage before.
i feels total lagginess during 99% ram usage.

does "how the windows manage system memory" won't makes me feels lag?

or .. does "how the windows manage system memory" , won't makes my ram usage till 99%????

Did u mean , there's no such thing as RAM NOT ENOUGH ??

it's actually due to one is nvidia chipset while the other is p35.
nv-chipset always got high read bandwidth.

shawty's tracer @sub-200 still available?
