Phenom 9950 Overclocking

[Chicken Patty]

nice oc there on x64.
what mem timings did u change? only 5-5-5-18? the rest is on auto?
i can run 3dmark vantage 3.3ghz with 1.45v (only using aod). raising the htt only 10mhz results in instability. guess it has something to do with my mem timings. i´ve got everything on auto except 5-5-5-15.

sorry, what post are you referring to?

That's right. This is 0836DPDW.
It's a little hard to 3.6G 32MB Pi.

Perfect. I'm going to hunt for a batch like yours.

thats the one I was trying to get but I got the 0831 CPCW instead, I even returned my first one at Tiger and they only had the "0831" stepping

"chicken patty"

your settings of the ACC what can we do?

"chicken patty"

your settings of the ACC what can we do?

what do you mean my settings of the ACC?

I have mine at +4 for 3.4 GHz.

sorry, what post are you referring to?

what do u mean with "what post"? i mean all the posts with screenshots of ur ramsettings. i just wanted to know if u changed anything manually other than the primary 5-5-5-15 timings.

Just wasn't sure.

My RAM at SPD is 5-5-5-18. THat is how I ran all tests, unless I stated I changed them. BUt all tests were ran at SPD which is 5-5-5-18 at DDR2 800 or 5-7-7-24 for DDR2 1066.

this is the best time i could do !
i didn`t try yet 3400 (200*17) with the 1066 strap and the ram at 4-4-4-15, but i doubt i`ll get a better result

[Chicken Patty]

^^^^ nice bro, how much voltage you feeding the RAM to have it a 640MHz

[EXxx]

i gave it 2.26 if i`m not mistaken
i`d go higher with the cpu but it won`t start wind even with 1.5 at 3500

[zif33rs]

nice Pi

best ive gotten is 23.515s at 3.45ghz running at 1.57vcore.

ram timings are slowing me down...cant seem to boot over 1100mhz at cas 5 at 2.2v. this is on 2x1gb OCZ sticks....changed over to the 2x2gb HyperX sticks as Vista seems to like more memory. they have horrible timings though. at ddr8500 they run at cas 7. having better stability running at the 400mhz strap with cas 5 timings.





Prime stable at 3.3ghz at 1.475v though. software readings of 1.488v-1.504v
220fsb 15x multi 2300mhz nb 2200mhz ht 880mhz ram cas 5-6-6-18 at 2.2v

ok, when i have time, tomorrow i`ll try 1.55 maybe it`ll start windows at over 3500
hopefully i`ll have a cpu-z and super pi

[zif33rs]

working on these settings now.




boots into windows but havent had much luck completing benches.

back at it...

[informal]

Amazing work people!Keep pushing it .And remember to watch the cpu temps and temps of pwm section

[EXxx]

working on these settings now.

you gave me some ideas

and my beautiful super pi

[Chicken Patty]

great job guys, I havent got much time to try and do anything lately, but my CPU doesnt wanna boot at over 3.45GHz, even with the voltage between 1.5v all the way to 1.63v.


I might be getting a Q6600 soon to do some comparisons, it'll be a great to have both and compare them in benchmarks.

However i am saving some money to see if I can order a Deneb as soon as they hit the stores, that'll be sweet

[Chicken Patty]

so far here is my most 100% stable 24/7 setting, i'm not focusing on max clocks right now, just need to get the rig stable

still working on it

[namegt]

My memory clock
ram : ocz 7200 sli (d9gmh) 5-5-5-15 2.4v

[Chicken Patty]

^^^sweet, I can't wait till my new ram comes in. Its some Crucial Ballistics Tracers DDR2 1066, should yield a big improvement over my current memory.

[Daveburt714]

Nice 24/7 setting Chicken Patty...

Here's mine.... I got lower V's, Neener Neener...

CLICKABLE:


That's almost an hour 4core Prime, heres a 10 pass Linpack run at the same settings:



The CPU's/Chipsets have gotten much better since the early days, I'm actually pretty happy with this setting. Until Deneb comes around that is...

It'll be nice if you can do 3.2 GHz stable at the same vcore

Of course, when the Deneb comes out, a new thread shall be made buahahahaha

My biggest problem seems to be getting my IMC speeds up. I don't know if my chip is just a little weak in that department or maybe I need to keep my HT multi and IMC multi matched....

I've noticed alot of people hitting 2.4nb are also running 2.4ht....

I've seen too many people kill their CPUs running high IMC v's, so I try not to go over 1.3 (stock). Guess that will give me something to play with tonight..

I'm waiting for that Deneb Thread though!!

Yeah i plan on getting the Deneb as soon as it hits the stores,

when you refer to IMC, what are you talking about, the Hyper Transport?

IMC = integrated memory controller

[Daveburt714]

IMC = integrated memory controller

Yep, that's what I meant...

The only reason I reference it that way is because Phenom is a little different than Intel based systems so I try to discern between the two... NB on an Intel system relates directly to the Mem Controller, while on Phenom the NB is more of an IO chip and the Mem Controller is on the CPU (IMC)...

It can get a little confusing and at least to me it provides some amount of clarity, since most Phenom bios have NBvid (IMC) and NBvolts (chipset/IO).

Chicken Patty: Hope that clears things up a little ...
Do you run your NB(IMC)Multi at the same speed as your HTMulti?
IE: if you go into AOD does NBspeed and HTLinkSpeed show the same frequency?

I've noticed alot of people with high IMC speeds have matching HTlink speeds...
