Help me with my TCCD sticks plz

[\Karting_freak]

hi everyone!
got these wonderful sticks from xgman
they are G.Skill PC4800FF with week 440 chips
with the 0516 FX-57 @ 9 multi they are able to do 300 mhz SPi 8M stable @ this timings:
Vddr: 2.8v increasing to 2.9V doesnt help to get more mhz
Tcl: 2.5
Trcd: 3
Tras: 5
Trp: 3
Trc: 7
Trfc: 12
Trrd: 2
Twr: 2
Twrt: 2
Trwt: 2
Tref: 133MHz 1.95us (4196)
Twcl: 1

Bank int.: Enable
Skew control: 255
Drive strength: 7
Data strength: 2 (4)
Max. Async: 8ns
Read Preamble: 5ns
Idle Cycle: AUTO
Dyn. Counter: Enable
R/W Bypass: 16x
Bypass Max: 7x
32Bit Gran.: Disable

i'm now going to switch to BigToes' 704-2BTA bios and see if it helps

any suggestions about the timings?

PS sry guys, no screenie for now as i'm using s3 2mb pci card that isnt able to show anything higher than 640x480 ((
gonna buy another card and get you some screenies

forgot to add that i'm using dfi sli-dr rev AC0

What is your goal?

Your timmings/DRAM settings are quite tight already. TRFC=14, TWCL-2 may allow you to gain a bit more stability, though. You seem to be on the right track with DS/DDS. Higher than DDR600 5-3-3-2.5-1T is where rocky road starts for a lot of average/good TCCD modules.

noob on board:

¿What means these things?

Tcl: 2.5
Trcd: 3
Tras: 5
Trp: 3
Trc: 7
Trfc: 12
Trrd: 2
Twr: 2
Twrt: 2
Trwt: 2
Tref: 133MHz 1.95us (4196)
Twcl: 1

@ bachus
my aim is to reach about 310mhz @ 2.5-3-3-X to get max bandwidth to play with my opty 150
i'll play with x2 3800+ with BH controller now and see if it improves anything
i'll comback soon

Well, don't get too excited just yet. It will take a lot more than good kit to get you there. Has this particualr kit been known to reach those speeds with the previous owner? Try TRCD=4 to see if that helps you get 310Mhz first. You will loose some bandwidth but fully stable DDR620 6-3-4-2.5-1T is a lot easier to come by for many TCCD sticks.

tref = 3120
preamble = 6
Tras = 8
Trrd = 3
Twr= 3
Trwt= 3
Trc: 7\12\16\18\20\22
Trfc: 12\16\18\20\22

dont try tight timings until you have STABLE timings for the speed you want, 8mb pi test is hardly that stressful

[\Karting_freak]

my hdd became crazy. looks like i need to install the new sys
@bachus
gonna try it tomorrow
@Ket
tryed loosing those timings before. improved by 2-3mhz but i gonna try it again
i know 8M isnt that stressful, but it is the sweet spot for becnhies and it takes only about 5 min

[\Karting_freak]

btw, what bios would you advise?
704-2bta or 623-3? or 510-3Fixed?

[stummerwinter]

I had mine (OCZ Platinum TCC5 and OC-Weat TCCD) running with 2,94 V at the DFI Ultra-D @ 300 MHz

Tcl: 2.5 (maybe 3.0)

Tras: 7
Trp: 4
Trc: 12
Trfc: 16
Trrd: 3
Twr: 2
Twrt: 1
Trwt: 3
Tref: 4708
Twcl: 1

Bank int.: Auto
Skew control: 0
Drive strength: Auto
Data strength: Auto
Max. Async: 8ns (or try 9 ns)
Read Preamble: 5ns (or try 6 ns)
Idle Cycle: 64 or 32
Dyn. Counter: Enable
R/W Bypass: 8 x
Bypass Max: 6 x or 4x
32Bit Gran.: Disable

I used the 702-1 from XS...

o yea, u might want to try FX60 beta bios, and screw benchies, benchmarks suddenly become 100% less impressive when somone asks "is it game stable?" and the thread starter replies "oh no, just benchmarks"

thats like me saying i can get my TCCD to DDR650 but its actually only stable up to DDR620 ish

[\Karting_freak]

@Ket
do you mean Oskar Wu beta FX-60 @ techpowerup? i'll try it to as i have X2 4800+ B2 controller

[\Karting_freak]

i HATE my sli-dr!!!
it crashed my ntfs file systems on 2 hdds
gonna try it again and see what happens ))
