Phenom 9950 overclocking

[Chicken Patty]

the link resets when I go there, I have to chose the board again and stuff.

Take a screenshot

well, there is a huge thread over on XS how people using the 0703 dont use ACC and stuff. But again, I havent followed it closely so maybe you can really use it now, I dont know

If gigabyte just would do that kind of descriptions on their bios updates... They have some problem to agree that their bioses have bugs. Haven't seen a single fix report on the DS4H bioses!

And there could be something weird going on with the ACC and Phenom II's. Because with newer PhII "optimized" bioses ACC will not work as it works on the older (F2 Vs. F3). At least that is the case with 9950.

woot woot!!!

Here's a theory on ACC that I ran into last night, seems to be legit and makes sense.
Say for ex. you use
1.35V on the core you add +2 ACC
1.375V +4
1.4 +6
1.425V +8
1.45 +10 and so on. So far I've been using this method and it works, although +2 works just as well. IDK its just that ACC is such a mystery to me. This makes sense of it, LOL.

Here's a screenie of 3.4ghz with 1.5V 12+ACC. Still havent ran any torture test on it yet, just not sure about running at 1.5V for extented periods of time.

acc is weird, I never saw any voltage increases due to ACC

I was just saying to manually increase ACC when you ramp up the voltage.

oh

THanks.

Well I dont know. I tried all the way up to +6 and 1.68v and nothing to make my chip run w prime at 3.4 GHz. funny is my best run in the leaderboard was at 3.4 GHz, but now it wont do it. GUess the chip has degraded over time

Thats weird dude, these phenoms are sketchy. Just the other day no matter what voltage I gave cpu, I couldnt get it to boot at x17 multi.

I left everything unplugged over night, psu, cmos batt, etc. Turn It on surf the web for a while. Then restarted and gave it a shot with 1.5v vid and core. Then it boots at x17. Weird.

haha I just need better cooling, im on factory heatsink bro.

 

[3dsage]

Well I found my new 24/7 Stable OC, on this chip. This chip is sweet.
3.2GHZ (1.5V) ACC 8+ 8+ 10+ 8+. Ran it stable 2hr's OCCT, which is like 8hrs orthos.
Max temps where 62C.

Also though i'd add this, I think this is a great FEAT, lol.
Over 10K

 

[Chicken Patty]

congrats 3dsage, I see you are really enjoying your build bro

Yeah man i'm getting some good results

You know those Drive Strength thingies under the memory section in AOD? AFAIK those are the settings of the memory controller. And I am 100% sure I did see them change in some point, some of them were 1.0x instead of 1.5x which seems to be the normal value. And IIRC, I did have my ACC on higher value back then.

3dsage, thanks for that voltage hint. I have been wondering why my rig will do sudden reboots if I go over 1.45ish Vcore... And that would certainly explain it because in some point I did some high MHz benching (around 3.5) and managed to get a more than valid screenshot (CPU-Z's of CPU, MEM, Motherboard + CPU-Z validation page) and of course the result of a bench. But now that seems so far fetch that I've been trying to do all as quickly as I can but still may get sudden reboot. Back then I used higher ACC values... 6-8%

Hopefully I will get my new best scores for super Pi and 3dMark06 with that tip.

laterz

PS. Have you seen any effect on NB clock stability with ACC?

my amd bench station. Air for now, waiting on some goodies to finish my water loop!

Hey dude thats how I got my rig to i'll post up a pic in a bit.

 

[Skywalker12345]

ha ihad mine like that too but i just put it in my case

haha, i love bench stations, just the fact that you can place fans all over the place is awesome

my main rig the i7 is in the thermal take case, but this one, I wanna see some silicon burn lol.

 

[Skywalker12345]

ha yea i had like 5 different 120mm fans just blowing air directly into my nb, sb, video, etc..

 

[3dsage]

Here it is, VRMs get suped Duper hot

 

[Chicken Patty]

thats awesome dude, thats the good thing about a bench station, easy to keep things cool and if that dont do it a house fan does

Haha, That will do that trick. A massive house fan

does for me

I know when Summer hits i'll have one of them with a bag of ice behind the fan , for some artic weather

haha.

What I plan on doing is sticking my rads in iced water, what do you'll think? But I gues I will have to insulate the board and stuff right?
