I still think that you just need to tweak a little bit the memory configuration setting... no big deal.

Your Sempron is based on E6 rev Venice.... therefore, such limitation is not relevant.

The reason why I ask u to tweak the memory configuration (the extra timings) is simply because the memory controller is in the CPU itself. Refer to dfi-street overclocking base results for your base setting, and then you start to tweak further from there.

I believe you never touched the extra timings yet don't u?

can you post your complete DFI bios timing settings?

already use LDT multi 3x? Maybe u need 2.5x....

try these....

HT frequency = 3 (or lower.... 2x if possible. if there is 2.5x... then use 2.5)


Row Cycle Time = 12 (or lower)
Row Refresh Cycle Timer = 24
Max Async Lantecy = 8
Read Preamble Value = 6
Idle Cycle Limit = 256clk
Burst length = 4 Beats
1T/2T memory timing = 1T

also try to bump your cpu voltage 1 step.

The thing is... each time you use different divider, you will need to have different configuration with the RAM.

for instance.... I can do DDR600 prime stable with 1:1 (300/300)

but the.... it wont prime stable at DDR600 with 9:10 (300/338). at first it wouldn't even memtest stable at that setting, but after a few tweaking i can get superpi 32m and occt finish, only that still have problem with prime.... error after 3hrs.

it can do prime stable at DDR540 with 5:6 (270/338). before that with 2.5-4-3-7, but then after some minor tweaking i could running it at 2.3-3-7.

all these are done by tweaking the extra memory options

actually cpu-z does not display it wrongly

it's correct

CPU/11 = DRAM speed... since the K8s actually don't have fsb.

The ram divided from the clockspeed, not 'FSB'

u sure u need so high voltage for that speed?

even my sempron palermo only need 1.63v for 2.7ghz

cpu only = custom 8K-512K (depends on L2 cache), in-place FFT
cpu+ram = blend

cpu-z validation is not enuff.... show some prime!

2800+ and below is locked because the Cool n Quiet support is disabled.

For 3000+ and above, Cool n Quiet support is enabled, and multipliers can be adjusted.

get a single rail with high amps is better than dual rails, unless you're going dual rails with 600w and above

There are newer batch of S-754 Athlon64 using Venice E6 core..... 512B L2 cache of course.....

Just update your mobo with the latest BIOS, that should pretty much fix it.

Yup...

90nm = 0.09m
130nm = 0.13m

Not bad I should say, but it's a waste to run TCCD 3-4-4-8 at only 280mhz

maybe you could tighten up the timings, 280mhz 2.5-3-3-7 sounds better. TCCDs can do that quite easy I should say.

micron should be µ actually ..... 90nµ or 0.09µ

yes....i'm wrong

damn.... how come didn't realize that i type nµ... memalukan diri sendiri
