so this is my previous highest fsb = 265 with 1.5VCore. but this is using previous 1333MHz KVR 2Gbx2.
HT link lower to 18**, oso the cpu/nb freq set to 18** because i didnt know that cpu/nb can be set higher than HT link at that time. plus, i didn't try with lower cpu multiplier yet. so basically i think the fsb is not the wall if i want to use current proc multiplier (*15)

i'll not find the stable setting for this highest fsb bootable because its 1.5vcore. highest i dare to use is 1.4vcore only. so i want to find the best setting between 3.4-3.7Ghz cpu clock if possible. even 3.4GHz oso got bsod...how to find the ram limitation and cpu/nb limitation? thanks for helping me

cpu-nb no problem at all.
Voltage for certain speed is almost the same at any htt x multi

for ram, low down cpu and cpu-nb.
test anyway u like.
prime with
min FFT = 1024
max FFT = 4096
memory use 3072MB or higher. use all ram if possible
minute = 3.

this is my preference. might not be the best but works for me.

cpu-nb volt 1.55v is consider very high already i think.
last time i bench with 1.6v for short time (and only superpi) i can feel its like deteriorate. some motherboard will show red even at 1.35v

low down the cpu multi? ok just lower it abit, increase htt a.k.a fsb a bit, ram reach over 1800MHz. suddenly bsod during stress tess, what to do. increase cpu/nb voltage or dram voltage?

timing?

set the cpu and cpu-nb close to stock.
increase dram voltage up to 1.65v (this is a safe volt.. u can go higher with no prob)
increase cpu-nb voltage to 1.25v

now push the ram.. what timing is that?

now HTT is 238*13 = 3094MHz
HT link and cpu/nb = 1910MHz
RAM = 1910MHz with CL9
dram voltage 1.55V,
cpu/nb voltage 1.22V. i'll increase again after this

u can try what dato kunta said... btw 3.9ghz on 1.5v kinda high is it... try set to 1.45v and up the cpu vdda to 2.56-2.6 it should be stable,
and please dont kill ur proc with that voltage huhuh...better keep below 1.5v for 24/7 use

hehe. just want to find highest clock for fun at that time. never use it. after reach 3.9, then set to stock back. now just begin to find optimum OC. urm...what is cpu vdda?

clock using Asus turbo unlocker

Placed my order for a 1090T already

abang fatalynx is hardcore tweaker.. he played with all kind of voltages
im not really sure about the vdda.its something that if increase, it stabilize the vcore supplied to ur processor. correct me if im wrong.i used adjust this back then if when using high vcore for quick bench.

nice2..fast2 update us with results.. esp the imc..kekekeke

okay...here is my OC on phenom x2 555 BE..




OC setting
HTT 240 *16
HT link and nb = 240*9
ram = 1333 mushkin 4gb stick
mobo = MSI 760GM-p33



will stress later...

i still can't find the vdda thingy. just now, i set the fsb a.k.a htt @ 250*12=3000MHz.
ram reach 2000MHz with 1.65Vdram (my mobo oredy show red in 1.58Vdram) but can't boot at all. so is this ram limit with timing CL9? i lower the htt to 240 but with multi 13, 240*13=3130Mhz, ram at 1926 CL9 with 1.60Vdram, able to boot. any suggestion? or the htt*multi must not lower than stock clock for the proc?

with deneb. there is near to impossible to get 2000Mhz ram

the reason to lower down the cpu clock is to eliminate the possibility that cpu clock not stable.. so that u can identify the problem is the ram as other clock leave at stock.

test with stress test? if yes.. now u already know ur ram speed limit. if u want to oc the ram further, try tightening the timings. if not, proceed with CPU-NB clock.

just now using this setting :
235*15=3525Mhz with 1.35VCore
ram and HT link : 1878MHz with 1.57Vdram
cpu/nb 2347MHz with 2.5V edited : cpu/nb 2347Mhz with 1.25V

then BSOD before able to run prome95. now tryin the same setting with 1.6VDram. or any suggestion? tightening the ram timing will need a higher vdram right? is it CL9 is still not tight enough?

every setting that i apply is using the same timing CL9 (9-9-9-28-39-1T)

cpu-nb at 2.5v? go look again..which voltage is that.
cpu-nb stocked at 1.1v (some proc 1.175v) and no way u can increase it up to 2.5v.

with deneb, u are safe to go up to 1.75v (this is my preference.. u may set ur limit to 1.65v)

quick stress test with prime 1min. around 15mins ok already. quick test not really stable but useful when u still searching the limit.

ops sory its not 2.5, its 1.25V. my mobo have range between 0.*-1.9V for voltage cpu/nb.. really sorry typo. trying to stress with prime95 (blend), about 3 minutes got BSOD oso after 1.6VDram...

cant really figure what problem u have here..as dont know the ram capability.

ok..back the dram to 1800mhz only.
increase the htlink multi to 9.

leave other value near to stock and prime again.. see if still occur.

remember to do things slowly.. straight away jump to high clock not advisable

value for CL oso leave to stock @ CL11? with 1.5 vdimm?
oredy set HT link to *9

now using this setting :
htt*multi : 225*13=2934MHz (stock 3000MHz)
HT link and cpu/nb : 2031Mhz
ram : 1800 CL9 1.5vdimm

now prime with
min FFT = 1024
max FFT = 4096
memory use 4096MB
minute = 3

suddenly this happen. why?

Normally this happens when there is lack of voltage
