heres my latest.going to see how high i can take this chip on air

9x540@4860 ddr1296 pl8 1m Pi


9x540@4860 ddr1296 pl8 32m Pi


9x543@4887 ddr1302 pl8 1m Pi


9x543@4887 ddr1302 pl8 32m Pi.......my first sub 10 32m


9x545@4905 ddr1308 pl8 1m Pi

[Jor3lBR]

Very nice RADAJA, now let's get me on some of those hwbot.org gold cups

G8 cpu you got there!

[radaja]

thanks jor3lBR. i think ill stop at 4941MHz
being that this is my first great cpu,i dont want
risk killing it by giving it more than 1.50v
using air cooling.but who knows,maybe ill get
the balls later,to try and go for 5.0GHz 1m run.

Dam thats a awesome CPU Radaja and very nice work. I so wish I had that CPU :p

[radaja]

thanks fatguy1992.i would love to see how far it could with phase too.

[Jor3lBR]

BTW, it seems like Gigabyte gonna release some new boards and this one should probably be the last ultimate LGA775 DDR2 board to have.

If this come out in DDR2 flavor it will be a pleasure to see what this baby can do! Comon 24 PHASE

Can anybody help me here?

I can't seem to get my E6600 to 3.6Ghz ...I get a BSOD on Windows startup or sometimes a few minutes into Windows at that speed.
With my previous mobo (680i), I was stable at 3.4Ghz with 1.30625v (1.288v CPU-Z) so voltage shouldn't be too much of an issue...even setting it to 1.4V yields the same result at 3.6Ghz. (Also, yes the RAM is stable if you were wondering)
These are the settings I tried for 3.6Ghz...

Any suggestions?

Those are your problems right there.

To leave those settings on auto is to ask for an unstable system.

Every CPU has a sweet spot and you have to set VTT to 1.20 and those two settings to their standart (0.760), then you will have to find on each one the sweet spot like -1 on CPU Ref and +1 on MCH Ref for example. You can only raise vtt from 1.2 after setting those.

Find a template that suits core duo and start from there.

To find out MCH Ref is easy, set it and Memtest #7 and #8.

it is ddr2

[OC Nub]

This EP45 UD5 is good news, i7 can wait even longer.

I want one

I hope its better then the current board, if so then I might pick one up

So should I keep VTT at 1.2v and play around with the CPU/MCH Refs? It's stable atm at 3.4ghz with both of those at 0.76v. What should my VTT be exactly (for 3.6)?

[The Viper]

Radaja: freakin awesome CPU, WOW from an E8400. BTW, where in the pacific NW are you from?

Jor3lBR: Does test #7, and #8 stress the MCH more I'm assuming? Test #5 stresses the RAM.

nate911: you will find alot of people say they like to keep VTT a couple notches below Vcore, some say raise it when you start upping your FSB
(ie. 450). Both are correct, just dont raise it too high. I wouldnt raise mine above 1.4 for 24/7 use.

@radaja

Awesome chip you have, come on break the 5,0GHz barrier

It´s a DDR2 version and with Gigabytes 2oc copper layer in the PCB and 24 phases I think thats gonna a be a awesome board, thee last ultimate LGA775 DDR2 board to have.

I want one

I hope its better then the current board, if so then I might pick one up

As i said, with Gigabytes 2oc copper layer in the PCB and 24 phases I think thats gonna a be a awesome board, it most be better then the UD3.

This EP45 UD5 is good news, i7 can wait even longer.

Sure can do.

The box and board says UD5, 24 phase, DDR2, and 1366+. Certainly looks like it is DDR2 to me heh.

[Jupiler]

I still like the board. Got my Q9650 running stable at 4300Mhz, 1.344V.

[radaja]

The Viper thanks. im in moses lake, wash.

Ghostleader thanks.i want to do it,5GHz
would be my highestOC to date.

Jupiler thats a very nice vcore for that OC.
being the vid is 1.25v.mine needed 1.37v for 4300MHz
great job

[andressergio]

Hey guys great great OC all !!! congrats to all

here's a little contribution for the quads, thanks to jor and hoss that helped me

Q9650@ 4824mhz (536x9) mems 1286mhz pl8



Cheers

[radaja]

andressergio,Q9650@ 4824mhz (536x9) mems 1286mhz pl8
thats just awesome!hell,im sure there are plenty of dual core
owners who envy that OC.youve got a great setup and you
got the skillz to do wonders with it.im sure your going to hit
5GHZ soon

thanks mate that's just a bench im runing 4545 at 1,4vcore with mems at 1212 pl8 for 24/7 wich is awesome

cheers radaja

[radaja]

well i finally got the balls and went for it.
i could only get 1m pi,32m still eludes me
this is my highest OC to date

9x556@5004 ddr1334 pl8


everest score

Stunning radaja!

Makes my current 550x8 look like a 486SX!

thanks so much guys.
couldnt have done it without all the help
and advice i've received here at XS over the past year.
