how bout ddr500 @ 2.5-4-3-7 w/ 2.6v?

my previous pair of tccd (gskill fc) like 2.6~2.65v only, highest stable clock done on nf3 ultra-d was 280MHz (mobo limitation).

225MHz at very tight timing oso no problem... js tat high speed kena.


Ahh... thanx for the tips.
Can u pls tell me yr RAM timing n drive strength?

this is d best i can give, other screenies gone as i've ledi changed to nf4.

in nf3, there were only 2 options available, either weak or normal, unlike nf4. so u gotta find it out yaslf...

thx ah khoo.

I'm able to do DDR500 now, Primed near to an hour ady.
I'm using 2.7V 2.5-3-3-6.

hey guys, help me out

i'm using ocz el platinum rev 2.0 pc 3200 (512x2) with tccd chips.

with 244x9 at 1:1 divider (2.5-3-3-6,1T), my sisoft score is 6100++

here's the 2nd situation,

with 325x8 at divider DDR133 (2.5-3-3-6,1T), my sisoft score is 6400++

why?

i thought with higher ram mhz, it suppose to run faster?


*anyway, my jetway mobo is limiting my ram overclocking ability over 250mhz , getting a dfi sli-d soon*

yr CPU speed boosted the RAM score significantly.

check this out..dunno if it's been reviewed before..hoping to get comment from u guys ....DFI

but running at 325x8 at divider ddr133 or 244x9 1:1 divider is better?

9x244 only 2.2GHz, but 8x325 has 2.6GHz. Higher clock speed usualy boost the memory bandwidth score as well. I dunno the exact reason, maybe the memory controller works faster (since it has the same clock as CPU).

Well, u hv 216.66Mhz RAM when setting 8x325. If the timing is tight, it can perform similarly with 244MHz at loose timing.

as you can see, at 325x8 and 244x9, both have the same timings, 2.5-3-3-6, 1T

the tccd ddr600 really headache, i am using aus board so cannot fine tune it, using a64 also weird la, cannot pass prime at ddr600 wif 2.5-4-4-8, always failed after 3 hours of blend test i currently doing ddr550 and most likely stable cause passed 5 hours prime but i lazy to continue it

u try using 7x325 and 9x244, i think the result should favour 9x244. 8x325 has high CPU clock ,tat's y the result is better

at least every1 better than me...
can't do even 250.
prime failed, for 200mb, 8-4096, FFT not in place, after 1 hour.

alright will give it a try later and see what's the different, maybe cpu speed boost up the score too

ok, done! i set it to 325x7 and the score drops back to 5.9k
so i guess proc speed does helps abit too. so u recommend me to run at 325x8(ddr133) or 244x9(ddr200) ?

In K8 architecture.... divider does not matter at all. Even if you run 1:1.... it is still on divider, because the RAM can never run at the same speed as the cpu clockspeed. Remember.... there is no front side bus in K8.

getting my new mobo soon dfi sli-d, hope can clock it at 289x9 with 1:1 divider and get great scores

Hi ppl,

I really need some help abt the timing.

I'm able to run until DDR466 with tight timings and passed 8 hrs 8-8192K FFT

Actually I've tried to change the CL from 2.0 to 2.5 for DDR468, but the RAM instantly failed Prime95, cant even do SuperPI 256K

Any suggestion on changnig the timing for DDR470 - DDR500 range with around 2.7V also?

The screenshot shows the timing @ DDR466, 2.7V, DRAM drive lvl 7 and data drive lvl 1. CPU is running at 9x311 = 2800MHz (with 3:4 /12 divider).

Thx !

Trc 7
Trfc 14
Tref 3120 for tccd

setting should be 2.5-3-3-5
DRam drive lvl 7
Data drive lvl 4 reduce 00
or put DRam 5, data drive 2
By pass max set to 7x
Idle cycle limit 256(my setting always)

for ram over 300mhz
set the Async Latency to 8, RP 4

Tref not 4708 the best meh?
