guys, my situation is:

able to do 2.5-4-4-8 @ 275 w/ 1t, no error in memtest.

but w/ same timing, can't do 300 w/ 1t(millions of errors), 2t gimme bout 150 errors in each loop in test 5.

bios everything is set to auto (mem. config), i've tried soulfly's setting but it gimme instant restart.

my setup:
as in siggy, my fc is of tccd chip w/ 2.8~2.9 vdimm.

any tips from u guys? kakaroto's tccd mem guide (from xtremesystem) doesn't work for me... i know, he's usin ff or le series, while mine is juz fc...

is it becoz of mobo limitation? or sumthg wrong w/ my ram (and setting)?

thx for any input guys...

yup bro... thx for d info...

well, guess i gotta aim for higher htt then...

to match d bandwidth 275 @ 1t, i think i need to do 31x-320 @ 2t... now only i know how big d gap is between 1t and 2t...

edited: not sure whether this fc can do 31xhtt or not...

i'm doin 311htt @ 2t w/ 2.9v (bios set), but in bios value displayed is 2.96V with my fc. 300htt gime no error nemore. again, everything is auto(for mem. config), thou there're some errors w/ 311htt, but i think it'll be fine after few days of burn in...

i'm findin d max freq of my ram 1st, hopefully it can reach 322htt w/o error then i'll ask u guys for help w/ d settings in mem config coz i've no idea to deal with it (too many options)...

hope u guys doin well too...

i wish i can run 1T for htt > 300 too, but seems like it's quite impossible. i've asked some users of 2*512 tccd/5, they're havin d same problem too. i can safely say it's becoz of chipset limitation on nf3 ultra.


i hope i didn't screwed up d ram... coz it cos me bout d $$ i've spent on my mobo + processor...

so far 300htt @ 2.5-4-4-8 w/ 2.96V memtest error free but can't complete super pi 32M... any idea guy?

my venice confirm no problem runnin 300htt, seems like this ram dun wanna coorperate...

tccd won't do 200htt @ 1T, sounds weird... is there a possible dat it was caused by mobo?

i wished i can have those 2*256 tccd module, juz wanna push d cpu + ram to d max...

i started to doubt d reliability of memtest coz my venice run fine @ 2.7 with my bh-5 (133 divider, error free), but w/ my fc, no matter how high d vdimm (1:1, error free) still it failed in super pi 32M...

gonna dig out d windows based memtest ledi. update u guys if i find sumthg new...

thx for all d input guys, esp raymond n master soulfly...

my fc onli like 2.5-4-4-x, even 2.5-4-3-x will give thousands of errors, regardless 1t or 2t for htt > 275, never try lower thou...

i've tried d windows based memtest juznow, 2.5-4-4-8 @ 300HTT (2T) seems fine, but i need to feed 2.96V for d ram, any lower will give some errors.

so d method i've found to burn in ram is:

1. run dos based memtest til' nomore error in all test.

2. run sandra burn in wizard (mem. bandwidth) around 100-200 pass

3. test stability w/ windows based memtest.

how bout u guys?

juz to share sum findouts i get recently:

300HTT @ 2.5-4-4-8 (2T) use 2.87V

280HTT @ 2.5-4-4-8 (1T) use 2.67V

i found dat 2.6V(bios set) is d sweet spot for my FC @ 1T, anyvolt be it higher or lower will give errors in memtest.

W/ 2T setting @ 300HTT or higher, 2.8V is d min.

yep...

tried almost eveything but still no go for 300HTT @ 1T...

do u guys tried the stability of ram usin memtest of windows version?

i juz tried it, error free 4 1XXX% but.... when i'm about 2 take d screenshot... i pressed ok then it didn't show d percentage ledi...

but atleast now i know 280HTT is the max for my mobo 2 run @ 1T.

guys, do u all mind sharing d genie bios settin dat doin 2.5-4-3-X @ 275ish HTT(1T ofcoz )? Mine can only do 2.4-4-4-X w/ 2.67V. Increament of voltage doesn't help, so i think it's becoz of d alpha timin.

thx in adv... hehe...

EDITED: I'll give mine 2ml... 4got 2 brin d detail 2day...

d latest bios(8/24) is almost d same, but it doesn't like venice, works well w/ sandy thou... 7/11 (d 1 i'm usin) juz slightly diff...

juz give it a shot, x harm tryin rite?

thx soulfly...


EDITED: juz dig dis out from dfi-street...

*basically juz copy & paste from review by raymond in his fc review...

i found out those in red are quite critical, wrongfully assigned d values will require cmos clearin > d thing i hate most...

yup, still no go for 2*512MB to do 300HTT@1T...

thanks...

voltage used? i noticed that @ 1T, tccd doesn't like too much voltage between 250~280HTT, mine like 2.6V, thou manufactured recommended voltage is 2.7~2.9V.

dunno much bout nf4 ultra, but i guess it's less picky (on ram) than nf3 ultra in general...

*pls correct me if i'm wrong...

r u on divider bro? try to run w/ 2.8V 1st, burn usin memtest of windows version for a day or 2, then try w/ 2.6~2.7V, i faced d samething last time too...

forgot dat u have a 3200+ bro, so no divider needed.

juz burn it for a day or 2 as per mentioned previously, it works for me...

yup, agree on that, genreally, tccd is more on tweakin & findin sweet spot (voltage) rather than burn in to get it run betta...

Sorry for OT

y don't u try d43? i noticed that sum of 'em are capable of doin DDR550, some even reach 280FSB w/ 3-4-4-8...

single sided d43 most likely can. not all tccd can assure u DDR550 @ 2.5-3-3-7 i would say. 2.5-4-3-X, yes.

*correct me if i'm wrong.

m.a = 8
r.p = 5.5 or 6
idle cycle limit = 0

i miss me tccd ledi...

increase vdimm mite help help...

nope, if failed in 32M most like isn't really stable.

do post ya DRAM settings too...

Trp = 4

try to loosen Trc, Trfc and Tras aswell. Generally ya timing is too tight I can say...
