Trying 2.5-3-3/4-X DDR600 on Gskill Le

[GoThr3k]

Hi,
have some problem, no matter what i try i cant get it stable at ddr600 :(
even with ras precharge at 4
i have al those less important timings relatively high, so thats not the problem either
my motherboard is a MSI K8n SLI Platinum :nono:
any advice??

this is what it does at 280MHz, 2.6V

nobody?
would increasing Voltage on NB help out?
i tried different voltages on cpu and i also tried 2.5X HT link

lots of helpfull people around here so it seems

Did you cut back on your multiplier so that the CPU isn't a problem?
Increacing voltages to other things will not help, unless they are the source of your problem. What FSB are you at?

Look at tref

Unfortunately not all LE's are created equal. I have quite possbily one of the worse sets of LE's I've ever seen. They will run stock speed (275Mhz) and pass SuperPI 32mb but that's about it. They won't last 5 minutes in windows memtest. Perhaps you have a set that just can't clock very high.

change trcd to 4

chips are 0440
they can do 304MHz 2.5-3-3-7 in 1M superpi with multi at 10X
i tested my DDR600 attempts with a multi of 5X

i tested my DDR600 attempts with a multi of 5XThe memory chips on your sticks are Samsung TCCD. I read here http://www.xtremesystems.org/forums/showthread.php?t=51896 that 0440's and beyond like higher Vdim than usual, 3v+, not the usual 2.7-2.8v, but I wouldn't do that just yet. See the pickey and try that. It ran SuperPi 4M at 300mhz @ 2.75v (not the sticks in my sig).

i think my problem is the motherboard
i dont have a fancy DFI one

[zungkono]

not all motherboard good, my geil one-s tccd and gskill gbfx tccd can do 2.5-4-3-6/7 1T 2.7xv@DDR600 on dfi ultra-d but my dfi expert limit my memory @275 (same timing):)
try your memory on other board.

dont have the money for a new one mate
and noone of my real friends are overclockers :(

I have the Gskill 4800LA (F3200DSU2-1GBLA) and could not make it to DDR600 @ 2.5 3(4)-3-7. It runs DDR600 @ 2.5-4-4-8 24/7 though... (all 1T)

[zungkono]

Have you tried DS/DDS level 5/1 or 5/3 ?

[Westley]

well i hv 4 stick of FC(2 pair).
but 1 pair i found out it is actually LD, inside there is another sticker:
rated
200mhz 2-3-3-6
275mhz 2.5-4-4-8

and it does max out 275.

From 2.5-3-3-7, most will loosen the tRCD by one cycle, or 2.5-4-3-7. I would also try giving some more voltages. 2.75~2.80V (or 2.7~2.85 depending on the sticks/mobos) seems to be the sweet spot with TCCDs at high clocks (i.e. 300MHz and above)

After 2.5-4-3-7, if you want to go higher, you will have to experiment yourself. Many companys like to program their higher grade TCCDs' SPD @2.5-4-4-8, but this could vary from modules to modules, mobos to mobos, and last, but not the least, CPUs to CPUs. I particularly find that 3-4-3-8 is more helpful for cranking frequencies for dual-core CPUs, than 2.5-4-4-8. But like I said, it'll vary on per-case basis. It takes time and trial-and-errors. (That's why I hate memory tweaking)

Raising NB core voltage can certainly help if your HTT is limited due to the chipset. Raising LDT voltage could help, too under certain situations. So try various combinations and check out Prime stable settings @ various sites. (DFI-street and OCZ support forum have data base, I believe)

BTW, are you getting 24-minish SP 32M, with only 2.8GHz?! What are the rest of your specs? Solid-state/I-Ram??

I did this with 3.0GHz / 1:1 / 2.5-3-3-7 (For 3D 2.5-4-3-7 needed) and I haven't been able to get any better time at or under 3.0GHz. Can you post your A64Tweaker (or A64Info) shots?
