Crank them up

i cant set the ram spec any higher than DDR1066 as the bios==fail but so far i have done 1200 CL7@stock volts lol

 

[Supreme0verlord]

Here is as far as I went last night/ early this morning (using AOD). As soon as I hit apply with a 20x multi I got a bsod, otherwise that would be 4Ghz.

What do you guys recommend for a max safe 24/7 voltage? I know AMD state's 1.55v as max safe, but how far do you guys think I could go without destroying this chip? I want to keep it for about a year or maybe longer so idk how much I should give it.

 

[ShadowFold]

I wouldn't go above 1.48v for 24/7 clocks honestly.

 

[erocker]

I can't get anywhere near those clock speeds erocker. How are people getting way up to 235 ?

My NB is at 1.4 and I bumped up the HTT voltage to 1.25. I'm actually running the same proc. speed, with a 2500mhz NB and a 2000mhz HTT now. The farthest I've gotten my bus up to so far is 265. It's a matter of setting the correct divider for the HTT and keeping it around 2000. Oh, my chipset is also water cooled, that may be helping.

i get 300 on my 780A stock volts for everything but that was @4x

toying with the chip right now

Sometimes you lower your muti to get there

Your NB could be to high

Your HT could be to high

That's why in real bios you should set them at their lowest setting

Also do this with your memory

Now in AMD with the memory controler on the cpu

YOU HAVE TO have high DDR voltage along with the CPU at the same time

Other wise if you just have high CPU voltage without high DDR voltage kiss your CPU good by
This can work the other way too, having to high of DDR voltage without high CPU voltage you can kiss your memory controler goodby which kills ddr over and over....it drives you nuts because you don't know what your doing wrong.

---

So go to bios

Turn HT all the way down, turn NB all the way down, turn memory all the way down.

Turn your muti down too, but not really low,

Turn up CPU voltage and DDR voltage along with NB Voltage(just don't go crazy with it but you still need to because voltage will pass through there.

Then Crank that ref clock up past 300.

When you get it to 300 then turn up your muli till you hit your max out and then start to turn up NB then HT

You will not be able to turn them up so high untill you turn your prog down. Benchmarks(3dmark06.vantage)will tell you where your sweet spot will be.

This is going to take you about 4 hrs or more.....
After that

AOD start turning your mem settings down one by one and running the AOD bench test. When it fails go back and try another setting. IF you don't know what a setting is (google)


Hope this helps you!

not 100% true on the cpu+high DDR volts i ran several chips @3vdimm and cpu@1.55v no issues at all. only time i killed a chip (my 720BE) was vdimm @3.5v and cpu @1.4v

Some are just more resilient than others. Take D's word for it, he's the master at killing AMD mem controllers. lol.

 

[DaMulta]

cpu 1.55v is high

you killed your chip when it was too low at 1.4

there is two different heats in the chip, if they are unbalanced too much it fries them.

this is true and mine was a ES chip with the older C1 revision memory controller

meh i still win as the 1st to kill a 720BE though day 2 after release


oh and 4ghz is stable

 

[DaMulta]

I wouldn't go above 1.48v for 24/7 clocks honestly.

psst if temps are good I would run 1.6v all day

 

[Wile E]

psst if temps are good I would run 1.6v all day

I wouldn't. Not on 45nm anyway. Temps don't do anything to help against electron migration.

 

[cdawall]

chicken 1.65v on water for a couple of months


making my way up

 

[Chicken Patty]

hows about adding me to the member list on the front page, im in the records @ 2nd place but not in the members list anywhere lol.

and hop on msn so we can chat

hey great run master I know you hit me up on MSN earlier. I just got back from the gym bro. I'll be on later.

 

[fullinfusion]

I wouldn't. Not on 45nm anyway. Temps don't do anything to help against electron migration.

Electron Migration on the Amd 45nm chips are not a big issue... The Silicon they Incorporated into the chip build helps with that problem at higher volts

 

[DV8tion]

Multa ... I've been working in bios like I said with the AOD thing it was just a run at a big number ... bypassing the boot issue LOL.
My problem is I don't have multipliers just the freakin speeds that the multi's would give you. I', working on it now.
I did try the lowered proc multi down to 14.5 and only got up to 217 before no boot.
Gonna try the nb and htt settings .....

my nb is at 2460 wich near as I can tell would be 12x and my Ht is at 1845 which would be 9x. System reports DRAMM:FSB ratio is 16:6 of course I can't find a way to change that in this friggin asus BIOS.

AMD's can take voltage like a champ!!

Ya Know it D
its been Provin

1.8v on a little TT rad things are a champ. These 45nm's have proven to take it like a champ as well. Thats what I love about AMD!

AOD?


you have muti in bios along with ref

 

[DV8tion]

the only proper multi I have in bios is the cpu multiplier.
AOD you know AMD overclocking thingy.

Have you figured out how to add up your clocks on paper?

An old fashion paper notepad is awesome to have when it comes to ocing

 

[Wile E]

Ya Know it D
its been Provin

They haven't been out long enough for it to have been proven. I'll wait to see how these things hold up to high voltage when they've already been out for a year or so.

Electron migration usually gets worse on a smaller process. I've personally killed 2 65nm Brisbanes by running them at 1.55V 24/7 under water. Took about 9 or 10 month for them to die.

 

[DaMulta]

By then they should of already of been dead lol then you have good reason to tell the old lady. Hey it just died IDK it hasnt happened in a long time....I don't think it was anything I did lol

Upgrade time without the normal fuss hehehe

have a look.......
A lot of work in that ...pathetic
