very high end spec there. btw i suggest you to have a look at your bios 1st. this is mine

you can find in your bios that something similar with mine which has cpu bus freq, nb, ht link, voltage setting etc. yours is BE edition. the special of BE is you can OC by increasing the cpu multiplier or cpu ratio.

other way, you can increase the fsb or htt. but we need to increase step by step in small amount. every step we need to boot into windows

tired of finding sweet setting for my 945. can't stable even 3.4Ghz with all other at almost stock speed stock voltage... maybe my cheap mobo can't handle such geli2 OC. only 4+1 power phase.

now trying to having fun with lowering the voltage core. 1.27Vcore 231*13 = 3.0Ghz cpu. ram 1854Mhz CL9 1.55vdimm, cpu/nb 2317MHz 1.23Volt, 230*13

blend test for almost 1 hours. hopefully stable. read somewhere got people doing 1.19vcore at 3.0Ghz stable.

update : passed 3 hours prime95

i'm having fun with undervolt setting now.
231*13=3.0Ghz, vcore 1.27V (stock 1.35V)
cpu/nb 1.23V, nb freq 2.3Ghz
ddr1854 CL9 1.55V
HT link 2Ghz

try to disable core by core, apart from mobo limitation (which i doubt so), sometimes weak core(s) can prevent one to hit certain clock w/ all cores activated.  smile.gif

wow can disable core by core? disable at bios or software - turboV?

1st time OC, then its very good OC result. rclxms.gif oredy reach 3.99Ghz a.k.a 4.0Ghz which is very hard for my setup to achieve. 3.9 on Deneb is like a dream for OCer. only a few can do, else didn't even reach 3.6 like me cry.gif

i already set dram voltage to 1.5v but nth change.
i saw come ppl nb frequency and dram frequency higher. how to make that?

you can lower your cpu multiplier and increase the fsb. then the HT link and cpu/nb freq will increase. but remember to use lower HT link freq to make sure its not run above 2000Mhz. cpu/nb freq you can run higher freq but mybe need a slightly more voltage to stable. rclxms.gif

Good job my friend for your 4GHz. But frankly speaking it was an easy run for 4GHz @ C3 Deneb base.  wub.gif

CL8 / 7 give u better performance. :nod:By increasing the multi to 19 and raise the FSB up to 210 is a basic thing dude. 4.2/4.3GHz on air is a dream for Ocer i can say. laugh.gif
*
mine oso C3 but not BE one..very hard to stable even at 3.5Ghz, perhaps my mobo can't handle it...btw mine is 945 C3. now only enjoying undervolt setting, OC the ram speed and cpu/nb but cpu at stock clock (use lower multiplier)

Did anyone know bout 990FX-UD7 from Gigabyte?

The mobo layout is awesome i can say. Solid with black PCB. Nose bleeding seeing this baby.

Guys, may i know now who using 990 board? Brand + performance wise?

wah oredy UD7? i only saw UD3 and UD5 at lyp pricelist yesterday...UD5 one RM659.

you just said your multiplier can go max 7.5X, how do you check this?
how do you confirm that it can go max at 7.5x?

Need to ask fellow AMD sifu-sifu here. Is this (attahced CPUZ picture) considered good enough? Or should I say, safe enough? If not, please advise me what else to modify. Thanks a lot, fellow sifu-sifu of AMD O/C here.

1.448 vcore for 3.5Ghz proc is a bit high.. later your proc fried.
and please keep the HT Link at 2000Mhz or below.

user posted image
the higher the NB freq is the best but, you'll need to increase the CPU/NB voltage

have you disable the Cool n Quiet? enable the cpu spread spectrum?
