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...

Memory Hole for PCI MMIO = Disable
Max Memory Overclock (MHz) = 200
1T/2T Memory Timing = 1T
Cas# Latency (Tcl) = 2.5
Ras# to Cas# Delay (Trcd) = 4
Min Ras# Active Time (Tras) = 8
Row Precharge time (Trp) = 4
Write Recovery Time (Twr) = 1
Ras#-to-Ras# Delay (trrd) = 2
Row Refresh Time (Trfc) = 16
Row Cycle Time (Trc) = 8
Write-to-Read Delay Twtr) = 2
Read-to-Write Delay (Trwt) = 2
Refresh Rate (Tref) = auto
Write Cas Latency (Twcl) = 1
Max Asynchronous Latency = 7
Read Preamble = 5
Dynamic Idle Cycle Limit = 0
DDR Output Driving = Weak Drive
DDR DQ Drive Strength = 50% Reduction
ECC Function = Disable

*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, those are very critical timings for TCCD. However, make sure you check using A64 Tweaker as the timings might change when you're in windows.

But anyways, it still doesn't help to run a pair of 2x512MB TCCD at 300MHz / 1T using that nF3 U-D mobo

I suggest that you loosen some values such as

Twr = 3
Trrd = 3
Trc = 7/12
Trfc = 14/16
Twtr = 2
Trwt = 3
Tref = 4078
Twcl = Auto/1
Write Cas Latency (Twcl) = 1
Max Asynchronous Latency = 8
Read Preamble = 5.0/5.5/6.0
Dynamic Idle Cycle Limit = disable
DDR Output Driving = Weak Drive

can post UCCC results here?

no off topic please

Hopefully This Thread can help you

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

thanks...

guys, is there anything wrong with my bios settings ?

it's for my Gskill LE PC4400 TCCD...

prime large FFT will fail after 1 hour.....

Windows Memtest also got errors.......

damn, need confirmation here..

can memtest(BIOS version) determind those faulty RAm(tccd)?
how to make fast checking upon the faulty RAM(tccd)?

try this....

Trc = 12
Trfc = 16
Twr = 2
Twtr = 2
Trwt = 2
Tref = 4078
Twcl = 1

Read preamble = 5ns
Async lantecy = 7ns

But I guess... it's pretty much the same like other common DFI nF4/TCCD settings

Can.... even OCZ use dos memtest.


1. Set you RAM at manufacturer rated speed, not overclocked setting. Also make sure you are using manufacturer recommended voltage setting. Other extra memory options leave at auto.
2. Go to Memtest86
3. Run test #5 for at least 500 loops
4. If no error, proceed to whole test for 6 hours at least.

Which memory chip for DDR RAM should we avoid if we are planning to OC??

No off-topic discussion plz.

ehh prend, if i put the extra setting to AUTO, it cant even boot.
do i need to try it at other standard board; let say such intel board wif no OC option??
sure all setting for those board r standard wan.

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...

hmr.....juz wana ask a simple question....would TCCD perform well on Intel too? coz mostly i see is AMD...

TCCD will work well on AMD 64 platform only. Intel motherboard lacks the required memory timings (tref,twcl,twr...) to get the TCCD modules working at high speeds.

If you plan to get TCCD and overclock up to 250MHz, I guess Intel motherboard should be able to take it... and maybe up to 275MHz. But surely it will be almost impossible to do 300MHz on Intel platform.

it lacks the most important - drive strength

hurmm.. what level shall be working fine?

TCCD loves weak drive strength.
