So is FM2 gonna be LGA?

Don't think so, maybe something like FM1 on Llano.. =)

Haiz..I was hoping they would go LGA like their Opteron CPU's sweat.gif

hye huys. need some advice regarding to OC phenomII X4 945.
lazy to stress test, so me just test with some game like grid and CS condition zero. suddenly game crash. my setting at bios is stock voltage for all.

fsb--> 225*15 = 3375 @ 3.37Ghz
nb freq 2250Mhz
HT link 2000Mhz
winova xtune set at divider 1600 CL9 @ 1800 CL9

my pc spec :
hyper 212+
phenomII X4 945
Asus M4A87TD/USB3
2Gb*2 winova ddr1600 xtune
powercolor 3850 512d3
WD GC 1Tb
psu ST56F

what else should i do. do i really need to pump voltage on VNB? i just want to get the best OC on stock voltage. thanks

fastest way to check whether it's d imc causing stability > lower d imc multi by a notch & check whether u still gettin crashes in games. wink.gif

Try increase the cpu-nb voltage abit.
And your ram at 1600mhz or 1800mhz?? You proc is c2 or c3 stepping??

imc means nb freq, right? in other word, to get stable i have to increase the nb volt? because if i lower the nb, let say from 2250Mhz to 2000Mhz, the perfomance is reduce. i just run the AIDA64 memory benchmark. so if ther perfomance reduce compare to higher nb freq, i think better keep my setting at stock... but no fun if stock. lol. very gian to OC...

1800Mhz CL9 with stock voltage 1.5vdimm. mine is C3 stepping

if ur ram are above 1600mhz it is best to set imc speed around 2600-2800 but make sure ur proc speed also equivalent with it otherwise there is no
extra gain of performance nod.gif
below are example of 18xxmhz with 3ghz of imc
usually i apply :
2200mhz 1.225v
2500mhz-2600mhz 1.26-1.275v
2800mhz-3100mhz 1.3v-1.375v (depend of proc speed)
usually if the proc speed hit 4ghz barrier it require a lot of volt for imc coz it fully utilize the speed of imc
just my noob experience sweat.gif

amd got suggest cpu nb clock at least = 3 x dram clock. unsure.gif

example:
for your DDR3 1600.
dram clock = 800mhz,
cpu nb clock = 3 x 800 = 2400mhz.
so cpu nb clock should be at least 2400mhz.

ok guys. please tell me in the bios, which one is imc?
stdd without OC
» Click to show Spoiler - click again to hide... «


OC setting
» Click to show Spoiler - click again to hide... «

fsb increase from 200-->225
ram increase from 1600-->1800MHz
cpu/nb freq increase 2000-->2250MHz
HT link speed 2250, i set lower multi to 2025MHz
increase the cpu/nb voltage 1.2-->1.2125V (4 step if not mistaken)
nb voltage is for what? this is stock 1.1V (range 1.1V - 1.25V)


and for the HT, i must keep it below 2K, means it shouldn't be above 2k right? so if i need to pump voltage, what is the safe voltage for cpu/nb, CPU and ram?

You can try fatalynx05 suggestion. Be sure to test stability using prime95 or running bf2.

Bf2 can be used to test your system stability. It is my personal opinion though. smile.gif


Added on August 4, 2011, 11:56 pmImc is the cpu-nb voltage. You are safe up to 1.55v.

However I would like mine to be around 1.3-1.35v.

mine is only from 1.2V to 1.4V 0.*-1.9V for cpu/nb voltage.

from both, i only have prime95. btw what i bf2? sory to many noob Questions notworthy.gif

edited : 1.2-1.4V is for HT voltage

bf2 - battlefield 2 bad company

The reason why i said it can be used to test the stability is because there is one time in the past my oc pass 12 hours of prime95 but bsod when playing bf2.

owh. i didn't have that game. basically, how long i should run the prime test, i mean minimum hours. because i'm running prime right now, if stable in minimum time requirement, i want to try higher clock brows.gif . very fun during finding highest stable speed rclxms.gif
now just past 1024k

update: after 1 hour prime95, i try to re-run WEI but bsod occur when the assesment is just about to finish. what should i do 1st. increase dram voltage or cpu/nb voltage first

u should oc by stage bro... find the max for fsb then cpu after that cpu-nb then ram...from that u know ur hardware limitation and have better target nod.gif
