eh u guys still getting double boot issues after oc? my ud3r even after f9 bios, still does the double boot thingy..

u can feed much vcore into 65nm, around 1.5v for 24/7 isnt a problem, the only problem is the heat generate, especially q6xxx that extremely hot.

guys,

I need ur help abit. i just overclock my e6750 to 3.6GHZ. here is the detail.

FSB - 450
Vcore - 1.456(in cpuZ)
VTT - 1.36V
MCH core-1.26V
PLL - 1.65V
NB and SB - +.1

is this setting normal to get 3.6GHZ? i see some people get it at lower vcore. pls advice

My bad, I actually meant PLL not VTT.

u do not need to add PLL until 500fsb for quad i guess, just leave it at auto, or do not exceed 1.6v.

1.456 for 3.6ghz is quite normal.
previously i used e6420 oced to 3.6ghz need 1.424v as well, the good part is 65nm has better dts thus able to show much accurate temp.

usually the settings i left it all to auto, except vcore, vdimm, and vnb..the rest auto..this can help me see how easy to oc this board...

Oh... MCH is the mobo voltage hehe, i think i up everything a notch. actually i didnt research much on the VTT, MCH, PLL, not really know wat r them. i just concentrate on vcore n dimm voltage. i will check tonite for my other voltage. may be try to reduce some and see what happen.

ya our qx6800 really hot! hehe.... luckily nowadays all the gaming mostly utilize the gpu else sure our cpu is cooking in there.....

By the way, i go rma my ram already, hopefully it can come home early....

raise ur MCH Core a little bit. maybe to 1.22v or so.

wat is double boot by the way? u mean after it reach xp loading there n reboot again or where did it reach to before reboot?

ur pc on and off repeatedly. mainly becoz of bios or low MCH core@NB voltage. (if i'm not mistaken)

i STILL have the double boot thingy even after i raised my mch core to 1.42v.

now i recalled back after i changed my back fan which is connected to mobo frm cm regular 1 (without led) to a vizo starlet uv led fan the problem start occur.is it the fan draw too much power frm the mobo?i have 3 fans connected to the mobo,2 120cm (both with led,1 is xigmatek xlf for heatsink and 1 is the back 1 frm vizo),and 1 80mm fan.

why dont u try boot ur rig without those fan. that way sure know for sure if that fan draw too much powah from ur mobo hence make the prob occur.

ok now confirm is my back fan edi,i shut down plug it out and then boot successfully without it

now thking a way to make it boot without any hiccups by plugging into diff molex

haha bro, same here.. i had a vizo at the back too. changed it to an old cm silent n its all well now.. weird. btw increasing mch voltage does not resolve it.

but there should be a way to fix it,not worth it to sacrifice airflow just because of tht

Glad u found the problem, but my advice to u is that get some converter and hook all the case fan to your psu is the best, that way it wont disturb your mobo or u can use a extra fan controller to control the speed. As for myself, i got a second psu to power all my fan and those extra stuff like your neon light.... that way u wont need to worry your main psu is over loaded hehehe.... Just my way, for reference only ya....

guys when i enable the DES on my EP45-UD3R, the power LED on the casing goes on and off randomly. however, the LED stays on if i turn off the DES. have anyone experienced this? wondering if it has anything to do with the MCH core??

i've tested it on different casing but no difference.. fyi, i'm running E8400 at 4.05Ghz (1.136v). LLC, C1E and EIST are enabled, Vcore set to 1.17500V, DRAM voltage set to 2.000V, the rest all set to Auto

4.05ghz at 1.175Vcore?

u mean something like this?

Yes, that will do. But remember tat will run your fan full speed as it draw directly from the psu. If u like to keep your pc quiet then u have to use a fan controller, no choice.
