Hmm... i'll try the settings. But then only 4708 (166MHz 1.95us) works best for me. Other is kinda unstable when doing SuperPI.

btw, my bypass max oso behave weirdly, bcoz setting to 7x can cause error in superPI, but 5x is perfectly stable when i was running DDR466 and below


The Trc and Trfc really works la
Now my RAM seems more stable than the previous one.

Well, if not mistaken, Anandtech has mentioned Tras = 6,7,8 works fastest on nF4 chips. I wonder if this is true.

thx again 4 yr help.

demand for PI, best lar...
sometimes do make it slower for stability

I've tried 3072 (200MHz 3.9us) and another number corresponding to 200Mhz 15.6us. Both Tref are not stable during Prime, 4708 has the best so far. I wonder why, it is suppose to be more stable for lower Tref as the memory is refreshed more often. Maybe TCCD likes slow refresh time ?

Try Read Write Queue bypass 8x and Bypass max 4x

Tried with DDR466 2-3-3-6. 4x seems to gimme prob after priming for 3 hours, same goes to 5x. I think the max allowed is 6x only.

Hmm... 8x Queue bypass ar? Slow in SuperPI
but i'll give a try later

Thx

if u ask me comment on corsair ram i would said that the heatspreader they provide was bad.

do you add any extra cooling to it?

for the setting, nf4U-D hv many guide over the web...
try find some oc record they have made...
use it for ur ram to test...

one question, did u ever burn-in the RAM before with high voltage? or any method of burn-in?

Hm... then i shall take off the heatspreader someday
I've read through kakaroto's TCCD DDR600 guide from XS, but the setings dont seem to be stable even booting into the windows


My highest was 2.8V, only tried once when i wanna reach 260MHz FSB DDR520 on my old school AXP for a screenshot of Sisoft Sandra BW ranking.

Most of the time I'm running 2.70V DDR480, 2.5-3-3-11 on DFI nF2 Ultra Inf. Tried prime95 for a few days for absolute stability check. After tat I'm folding almost everyday for 6-7 months with this RAM.
I wonder if the RAM is too used to the old system till refuse to go high clock. Maybe she still thinks : hey, tis is nF2, dont go so high !

If you burn-in them at CL2.0.... probably that's why it wont run with CL2.5

heard cases of burned-in TCCDs that refuse to run at higher speed, only tighter timing at lower speeds.

some said mostly happened to tccd yr05...
hv tried, those can do weird timing after that.
in 1 case, there is a guy push it like bh5, 250 cl2
voltage, 2.8v and above...

i dunno, but is quite weird...
the tccd currently 1 owned, tccd 431 which can run
200@2-3-3-6 only, 2.75v

another which is 440
able to do 300@2.5-4-4-8
and 200@2-2-2-5

need help from otaku2 here...
why my ram dont want to use divider a?
everything is working fine when i use 1:1..when tro to use 9:10..got prob..

fsb 300
divider 9/10 = 270 (DDR540)

can boot into windows..but after 5 sec..BSOD will appear n pc will restart...why a?

my current settings:(no problem at all)

different divider may need different memory controller setting.... believe me.

try read preamble 6.0ns, and play with the Idle Cycle value

owh ok..thanks soulfly

who is doing 4x512MB?
need your help.

Ohh... icic. Well, i burn in with CL2.5 DDR480 wor.


How to see 431 / 440 ?

Mine can do 2-2-2-6 up to 210MHz default voltage
211MHz above must use 2-3-3-6, as pushing up the voltage help nothing.

2-3-3-6 can scale up all the way to 237MHz with 2.75V, and tight alpha timings.

2.5-3-3-6 dunno yet, still trying with 2.70V and see how far it can go. However, I must loosen up the alpha timing, else it will gimme errors in SuperPi and failed Prime in a few seconds

charge-n-go

to see the code, u hv to remove the heatsink.
it is great that ur TCCD can do it.
but mine, no hope, 1 pair can do, another can't.

after 1 week burning and tweaking, the system able to run @ 2.74V 200mhz.
i hv tried for 250mhz, but no matter what effort i try, it won't be able to prime sucess for more than an hour.

sorry to hear abt yr not so good TCCD.

Well, i've js tried DDR510, with 2.5-4-3-7 @ 2.80V

It js cant pass prime for more than 1/2 hour.

after can't make it @ 250, i hv to tried for 230, good news is it passed 18 hours prime and continued...

and it is running @ 2.72v(bios 2.77v but undervolt in windows so much)

my teamxtreem succesful make it to ddr600 at last with my asus board with 2.9vdimm, i added a fan to active cool the ram, so it wont fail after 3 hours of prime, and do pass 7hours 45 min...

Only DDR510? Your timing is quite loose.
At vdimm 2.8v, You should be able to hit 275MHz, at least.

Are you ram modules in the orange slots?
