**CONTINUED**Phenom stepping/batch overclocking database

[Oese]

here's what i did today, vista 64bit.

but i did not get the 3h, rebootet after 2:41h. i think psu or pwm section is weaking, as the power meter showed a crazy 447w just prime no grafics.. after 6h of 3h prime attempt i got screaming pwms and such but now they're calm again luckily.. thats although pwm's stayed @ 66°C thanks to the fan over it..

perhaps theres more to come with full watercooling

284HT O_O...

highest ever. an 3.4ghz on 9750, I couldn't get my 9550 to lower it's NB after 220HT it unstable.... nothing I did would work then again this was on 780G board with sb700.

[Oese]

yepp that 9750 is crazy. and i think this would not be possible on another board as well. that phenom sucks power its unbelievable. i think other then these digital pwms on the m2r could not stand that.. perhaps that 10phase system on the msi or the gigabyte dq6, but no 780G/790G/GX board i believe..

hi Oese, nice clock there... mind to guide me a 'lil as i'm struggling to get pass 260HTT prime stable.

this is my highest so far...

10 phase where ?

I know the MSI K9A2 only has 5

I've got ajetway 780G HA06 has 5+1 on it.

looks liek that Dq6 might have 6+1 on it.

that board became rare quickly though.

Vista 32 here....Nice one Charged....

[Oese]

i'm glad that actually a lot of people here hit such clocks, enough knowledge and a newer phenom provided. thats really good to see!!

@ ah khoo: i think its very board specific if its really the htt. but one thing is surely set all the trefs to the same value for all 4 ram slots, to the highest value required for one of your rams. even of the slots unoccupied. also set nb and cpu voltage the same for testing.

furthermore, i have experienced some bad behaviour with the 667-ram divider. perhaps its really something in your ram/imc related settings. to test, set 533 if that occurs and your ram cant handle 800 divider.. but i think just like with the amd x2, that behaviour can be chip-speific. i just want to say play around with those multis, noone knows whats going on there.

I'd think you could try another ht/nb multi as well. your chip should run with one setting higher as well.. and perhaps something is hindering there..



phenom @ 300mhz htt its vantage stable but does not that much on my score (P8500)... single 4850 only..

3,4ghz (300x11,5) isnt possible with this ram setting at all. if i give it more power, it will shutdown earlier.. clear sign its the psu..

Wow! What is the secret of the 300MHz HTT?

Wow! What is the secret of the 300MHz HTT?

With everything else turned down to accommodate it (CPU, NB, HT Link) I'm not sure a 300 reference clock is that big a deal.

3.3 GHz - now THAT'S a big deal ...

[Oese]

right. nb/ht of course must be lowered to get such ht reference clocks done. with my nb especially, as it can do 2380mhz as a maximum, so 300x8 would exceed the maximum stable nb clock for me.

the other thing is the board must be tuned right in those specific settings.. with the m2r it is htt boot up clock must be set the same as htt reference clock. adjust gap is set to 5mhz.

besides that, all board related voltages are just stock

hehe @ quiet ice: that 3,3ghz is not that much for this phenom. I already had prime running @ 3,4ghz, pi 1m running at 3,53ghz, a 3,53ghz validation of that run can be found at ripping.org as the world record with 9750. Its a miracle chip. But also the m2r with the newer biosses is a miracle board for phenom OC, especially because of the superb pwm section.. but whatever, i think its the first phenom with 300mhz htt

[QuietIce]

I bet if you turned everything way down you could hit 300 MHz clock as well. The question is, does it do any good to get there???

The "Bus Speed" (ala CPU-Z) on the AMD's haven't changed since the single-core A64 days. It's still just a reference clock
that's multiplied by some other number to get the given component's speed. The reference clock by itself does nothing ...

RefClock 200 400
CPUx ......14 ...7 = 2.8 GHz
NBx ........10 ...5 = 2.0 GHz
HTLink x ...8 ...4 = 1.6 GHz
RAM .....800 .400 = DDR2-800
etc ....

The reference clock speed is doubled but there's no advantage there. I can see situations when you're end tweaking
and may have a need for a high reference clock so the multipliers work together better ...

[nuts24]

I got my new mobo at the weekend, which is a Asus M3A78-T (790GX/SB750), Does any one have any tips on how to set this up? Do I need to do any thing in the bios or can it all be done via AMD overdrive? Many thanks for any help on this.

Also why is the table gone? What has happened now?

[Oese]

@ quiet ice: of course you're right! its just to bring ramspeed and cpu together. but for 9750 and 9550 its important as you cannot change the multis freely.. so i'm totally pleased with this !

[QuietIce]

My bad - I missed the fact you were running the RAM flat out.

DDR2-1200 ...!

[HondaGuy]

nice run Oese.....

[gOtVoltage]

Yeah very nice run
Even up to 1150mhz with my ram ,, i was limited to 288 @ 3.3,,Again Mobo and Ram dependant....These Cpu's can handle more than Mobos can Dish out...

Maybe the 45's will bring the Mobos that can actually clock these things .

,,The Way They Were Ment To BE Clocked,, ah no I did not just qout Nvidia did i?
..Stup Crysis is stuckin me head again

[charged3800z24]

Vista 32 here....Nice one Charged....

Thanks.. I have been watching you and GotVoltage cranking your chips pretty good. I was actually shocked to get Bios OC 3.4ghz And be able to load Win XP 64. And it runs prett good. I haven't tried anything but Pi, I need to get more loaded...3.5 on win XP 32 is not completely stable yet... needs som tweeking.

I think Phenom has just started to sho some nice improvements.. to bad it could not have been earlier..I am still happy...

[Oese]

gogogo

unfortunately that 300x11 ddr1200 is not prime stable, although 3,3ghz and ddr1200 is stable alone.. perhaps its the chipset, but it gets very hot so i dont want to rise voltage there.. need watercooling !!!!!!

and youre obviously right gotvoltage these chips really exhaust mobo and psu it is not amd's fault

[HondaGuy]

I hear yea Oese...cant wait for my H20 to get here and put some real volts to the cpu...Air cooling just not cutting it...

I'll get 2nd place soon over gOtVoltage in 3Dmark06 one of these days...

[gOtVoltage]

..........

[Oese]

hehe i need a second 4850 and a new psu but not this month

[HondaGuy]

I was putting way to much Volts to this chip before,, just encoding a video on this pass...

hey Honda where did you get the gadget above in the right corner ? or what's it's name?
hhhmmm maybe I need a better cooler I'm hitting 53-54C on load.

although my PS keeps going one day stopping the next :/ ....
