Phenom 9950 overclocking

[p_o_s_pc]

yeah bro, im sure it does, just make sure it stays cool

Will do.. i have been thinking about DICE and trying 4ghz but not ready to go that far yet. I think i am going to take my rig to the garage the next day that we have thats ~0f that should keep my temps nice and low... Also what would happen if i was to try spraying R34A onto the HS? I know that stuff gets really cold

 

[Assassin48]

Also what would happen if i was to try spraying R34A onto the HS? I know that stuff gets really cold

Its got to be continuous spray because that gets HOTT!!!!
just get some dice and a Copper tube might be going that route myself

haha, I have no idea what would happen dude,i'm sure somebody has had to try that eventually

hmm i may try it. maybe save it if i see temps getting out of where i feel safe. like the poster before you said i could try copper tube and DICE but would i have to insulate my board?

what gets hot? The spray or the heat that they put out at stupidly high voltage? also could you PM me with some details/ ideas on the DICE

Here Are some Pros And Cons on Having DICE
Pro:
Extreme Overclocks
Stays Cool
DICE is Cheap $1.15lb plus handling charge

Cons:
Non 24/7
Cold Bug
Board Must Be Prep
Condensation

I would Go with a nice water cooling setup mine was around $600 it was well worth it my temps are 18-20C Idle 30-35 Load plus it makes your pc look cool

Here are some sites that show the prep work that goes into DICE

hey man that was very valuable. Sorry if you might have posted this again, but do you mind giving us some detailed specs on your water cooling setup?

 

[LeMoose]

got a general question for you'all

My mate's got a Q6600 and clocked that mother to 3.7ghz at 1.44 rock solid in prime.
That's from 2.4 to 3.7 without a sweat

And my 9950 doesnt last 5 seconds in prime at 3.0 with as high as 1.45 volts

Is this generally how things are AMD-versus-Intel wise ?

How about a water cooling set up and fill it with a 50/50 mix of purified/distilled water and coolant (antifreeze), and then place DICE on the radiator when taking a serios OC session...

PS. That just crossed my mind

There is much more to work with when overclocking a Phenom. Its nothing like an Intel chip. Keep reading up on it and you will get how they work and don't work. Don't give up!

 

[fullinfusion]

are you stable at 3214?

Hey Guys i just got home off the road and my x-mas prez was sitting here waiting for me.... i finally got the M3A79-T Deluxe mobo and cant wait to see what this baby can do...
i'll post soon after she's installed and tell ya what rev and bios she came with...

I dont know about water i use freezer One because it works better then distilled water in moving heat and if you mix the two you raise all the conductivity so if you have a leak it will BLOW UP jk but you will have a mess

when my tube disconnected my 4870x2 got really hot and my computer just shut down nothing major happen i just wiped off all the coolant drained it and fix the tubing and it worked again

you could put the rad in a Cooler you just have to make sure that the Coolant doesn't freeze

i was going try getting 2 triple 120 rads and make an enclosure for them with a separate psu with a bunch of fans in it, that would get you some awesome temps but that's just my theory

and it depends on how your loop is, before mine was like this
RES > CPU > GPU > triple 120 Rad > Single 120 Rad > RES
the load temps were almost hitting 46C under load
and now.>>
Res > Triple rad > cpu >single rad > Gpu >Res
load temps are much reasonable around 30-35 on load


My Setup
XSPC Dual 5.25" Bay Acrylic Reservoir
A Danger Den DD-CPX Pro 237 gph Pump
1/2" ID (3/4"OD) Anti-Kink Tubing - UV Carribean Blue
Danger Den Black Ice GT Stealth 360 Radiator
Alphacool NexXxos X2 Bold HighFlow+
Danger Den Black Ice GT Stealth 120 Radiator
Koolance VID-487X2 (Radeon HD 4870 X2) VGA Liquid Cooling Block
i have to upgrade some parts like the pump to a 317gph

Hey :0

You were right about getting 3.300 stable - worked on it last night and ended up with this - rock stable
Was thinking about getting some pc2-8500 ram - now I'm not so sure I need to. Ran memtest on this clock for an hour and a half with no errors so looks like there's more to go yet
Only thing that is stopping me atm is the heat issue, fairly sure that my sys was kicking out more heat than my radiator in the room last night when It was stress testing!!

The cores were stable at 58C and the overall temp was 56C but that's using some really nasty thermal grease (3 sachets good for 3 apps min for just over £5!)
Got some Zalman ZM-STG1 Thermal Grease on the way so hopefully That's going to take my temps by a bit so I can go for a bit more

[img=http://img360.imageshack.us/img360/3834/oc1jx1.th.jpg]

I'd love some idea's where to tweak from here to get that little bit more out of it..

Just one thing though _ I can't afford a new CPU atm so nothing too drastic

the 79-T mobo i have came with 0302 bios.... what is every one else using... i want the most stable one plz

I just fell in love with AOD. I realized how much it saves time to do a comparison with different settings (if you wont go to extremes = BSOD).

I found someone from XtremeSystems Phenom II overclocking thread telling that HT Link affects to the data speed between GPU and CPU.

The other thing I haven't ever really tried or done, is the PCI-e bus overclocking.

So I started to try out with RT HDR IBL (Real-Time HDR IBL). I put 16x Multisample on and streched the window so the FPS went down to about 20. Then I lowered HT link to x6 and saw immediate FPS drop. I freezed the screen in the program. Then I upped the HT link step by step and kept an eye on the FPS. In that particular case I got about one FPS more on every multi step. I went from x6 to x12. My HT Link is now @ 2484MHz. I didnt see (in this particular situation) any significant drops or highs. According to this graph HT link would be best @ 1800MHz when looking at the 3Dmark result (once again in that particular case) but all I saw was just increase in FPS when increasing HT link.

Then I kept the HT Link at x12 and started to fiddle with PCI-e speed...

(Here I want to state that the RT HDR IBL wont keep the screen freezed for long if you dont do anything. I didn't find any help for this in the menus. Still it kept frozen when I played with HT link. You have to make the changes fast for it to stay freezed, this would need more research.)

Here I had a bit difficulties to keep the screen frozen but what I found was that from 100MHz to 108MHz there was about 0,1 FPS difference with every 2MHz step until 108. Beyond that FPS started to just drop. I tried 120MHz maximum.

My settings were as follows:

HT Ref 207MHz
HT Link x12
NB Multi x12
CPU Multi x16
Mem @ 1102MHz

Radeon HD4850 @ 700/1090MHz

ACC +8 all cores
I tried AMD boost and it didn't affect FPS because the RT HDR IBL is GPU bound.

So what I would say from this is that try to reach as high NB and HT Link as possible to gain maximum FPS in games.

@Meizuman does the HT afftect the Anthlons too?

 

[Meizuman]

@meizuman does the HT afftect the Anthlons too?

The only "Athlon" I have is my socket A Sempron 3000+, so I really can't say anything to your question.

Btw. After a while I fired up that old badass and got some results @ HWBot... first place in CPU-Z and PiFast, check it out http://hwbot.org/user.do?userId=19261

Edit: Oh, I forgot to mention. On air. Spire Verticool III

And one thing. Could I use 1200MHz (PC2-9600) DDR2 on my rig...?? It would be much easier when I wouldn't need to think so much about how high my mem is going with HT ref clock XXX and x5.33

http://xtreview.com/addcomment-id-7061-view-Phenom-X4-9950-Black-overclocked-to-4.1-GHz.html This link answered my question "This last was coupled with the motherboard DFI lanParty DK 790FXB-M2RSH, on base of AMD 790 FX chipset and A-DATA extreme edition DDR 2-1200 memory."

OMG!

Maybe I'll by some 1200 for christmas... I should get better fans too. Maybe a Silverstar FM123 would do the trick. I just would need to know how much noise they are putting when used with controller @ low speeds.

Check this score out for the new Phenom 940 Mk II - over 5 Ghz !! I was thinking about getting the Asus board most of you are using but now I'm not so sure, They used the same as I've got to set this score so If I cant hit 3.2 Stable then I'm going to be really pissed off!

K, just found a couple of things you're not going to see every day!

1st Microsoft telling people to use Firefox!!!! and also a working copy of what's possinly the worlds first computer - a must have if you're a pagan!

Hey Brad, congrats on your purchase of the 79-T mobo, from experiences, i'll tell you, its the best buy ever bro.

I used the 0403 BIOS, was the most stable and less buggiest for me bro, give it a shot, you won't be dissappointed. Keep us posted bro.

I told you bro, its a matter of tweaking, Phenoms aren't easy to overclock bro, the more you work it the higher you'll go, remember that.

Dude, now that I have owned both rigs i'll tell you something, I thought Phenoms were not hard to overclock. I take that back, they are pretty complicated chips bro. Even my intel rig which does not have a unlocked multi, is much easier by far to overclock than a BE phenom.

However, you feel more accomplished when you get a good overclock in a Phenom since it is much harder to do so.

CP i need help!!! with the old mobo it was esiere to o/c... this 79_T is a bitch.... i set the settings to the same as the old mobo to get my clock but this ACC is fu^*ing me up BIGTYME!!!
I have the cpu volt up to 1.40v
and ACC +2 and any higher she BSOD mate!!!
i think the clock (cpu( voltage needs to be bumped higher to allow the ACC to work.... what do ya think?

 

[Meizuman]

Did you bump the SB a bit?
