But now with 8320e i cant i can put very lazy timings and up voltages and still wont boot it only boot well with 1333mhz and with 1600mhz its sometimes freeze. I made memtest86+ and all my sticks was good any tips maybe? Board is UD7. So memory controllers on FX series are worster than am3 cpus?

Vishera's IMC is much better than phenom's so I'd eliminate that from the list of possible causes.

I'm not familiar with your motherboard at all, but the basics are - find the settings that the ram is rated to run at by looking at the sticker on the dim or using the spd tab in cpu-z. Then apply those settings manually into bios. If it's stable bump up to the next higher speed settings, if not, either loosen the timings or lower the memory divider - OR bump up the voltage to the ram or the cpu/nb and try again. I've ran 1.4 volts to the cpu/nb without any issues but my boards are much different than yours.

I would have totally replaced all wires in the house... but they used 8 gauge solid 3 conductor wire, each conductor is .125 thick... awesome wire, they just didn't bother to hook up the ground in some rooms for whatever reason... most did have it though... weird... kookoo.gif

12 gauge = 20 amps, 2200 watts @ 110 V
10 gauge = 30 amps 3300 watts @ 110 V
8 gauge = 40 amps 4400 watts @ 110 V
double the watts for 220 V

I can see using 8 gauge if it is 12,000 feet to the 20 amp circuit breaker from the plug. Are you in the Merriweather/Post house in FL ?

Nothing helps i tried all them what you sugested. I got stable with 1600mhz but no booting with 1866 even when you bump up voltage to 1.7v and cpu-nb to 1.35v not even very lazy timings 11-11-11-34 T2. Maybe its becasue i have 4 sticks and i have heard FX cpus dont like 4 memory sticks. Maybe i just use 1600mhz and tune it very good timings or is 1866mhz very importand for perfomance boost to FX cpus?

fill out a rig builder... you might be more responses that way.,...

top right corner of ever forum page... then add it your sig.

Did you choose xmp profile in bios? If not select it. Because it adds more voltage to VTT, VTT voltage is lower with xmp profile disabled, so that could be the problem.

Stability>NB frequency>Ram frequency>primary timings> tertiary timings is about how I see it with these chips as far as bandwidth goes. For latency it's probably more about the primary timings and command rate. I'm probably the world's worst memory tweaker however.

What is the exact part number for the ram kit that you have?
And yes, please fill out a sig rig.

you dont have xmp profile? Are you sure? what mobo do you have?

If you dont have, then try to find VTT voltage and set it to 1.35V, memory voltage to 1.50v if 1866 is stock, if not set it to 1.55v

No such thing like VTT voltage in my bios but i tried DRAM E.O.C.P and set it 1866 and that changed my voltages and timings but still no booting.

same memory run with that board easly 2000mhz with phenom x6
