Phenom 9950 overclocking

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?

You should try that right now and see how the temps drop.

You think it will rust your rads??IDK dude.

who cares, its my benching rig. Maybe there is a proper way to do it?

Well Im missing pump and reservoir so I cant do this yet, but once I get it running, i'll find out some more info and try it out. I think system viper has a similar setup if im not mistaken, maybe not though, I dont remember correctly.

LOL, yea man I have my laptop in case I destroy anything on my bench rig.

Its all for the bigger cause Right?

L2 cache and ACC

Whenever I activate ACC my L2 cache drops to 128k per core, it happens on auto, all cores or per core except when ACC is set to +4, then I get 256k per core of L2 cache or +8 when I get
512k per core (usually won't load windows at that) I ran it stabily @ 3ghz (15x200) with ACC set to auto and vcore set to 1.4v for many weeks until I realised my cache wasn't all there. Now I run ACC off with vcore @ 1.4v. I can't complete prime95 at 3ghz no matter what I try. Highest I can complete it at is 200x14 @ 1.3v.

any advice please?

9950 140w

Worked my ass off last night, I had an idea to make a custom cooler for VRM's from an old stereo amplifier which had kinda solid aluminium heatsink. I used a metal handsaw to cut it... and I did it outside where it was something like -20C... Eventually I got it shaped. I did few mistakes that cost some of the heatsinks size. Today lapped it and tried it on but I should finish it better and paint it black. Should get some thermal tape or something because the VRM's doesnt seem to be on the same height. Maybe I'll make something for the northbridge also... I did just a quick test and I would need something better to northbridge first. Tried a little zalman NB heatsink with 40mm fan. Just with stock clocks... Can't say much because MB was on the table. Though it froze in Prime95 with stock clocks so... I put the original back on. Found that the original cooler is really crappy. The fins have been glued to the base, also the heatpipes are glued to the fins, rather than soldered.

@xFOADx, that sounds really weird... you use CPU-Z to check it? I would say that it's just some bug in program.

Figures the VRM's on this board heat up, after I put two 60mm fans on them my cpu temps drop a few degrees.
I cant believed they are glued together and not soldered, talk about cutting corners.

I know there is to many 9950 owners around.

Just wanted to throw this C4D run on Vista 64.

BTW I had no troubles with my Vista 32x, stable oc. while running 64. I thought I was going to have to drop some settings.

hmmm, I dont even remember what I scored in that bench with my 9950. GUess ill run it when i get it up and running, waiting for the new PSU

This morning I was playin the game of "OC'n" and made it to 3.2Ghz on the 9950 B.E. I have a screen shot at home hitting 3.2Ghz w/ 1.475volts running AMD stability test for 30min without issues. I did try for 3.4Ghz @ the same volts but Vista locks up @ the loading screen. After playing Gears of War for a little bit I went back into the bios and moved voltage down to 1.465 and again it passed the 30min AMD stability test so tonight I'm going to try some more.

 

[kenkickr]

I did get voltage down to 1.45v but after 20min of the AMD stability test the LCD got all gooble goop and the system restarted so it looks like @ 1.465 is my sweet spot. I forgot to put pics on my flash drive this morning, getting my daughter ready for her long week of testing in 3rd grade...YEAH, 3RD GRADE!!

Yeah good stuff man
3.2GHZ seems to be where this cpu stays stable.

Mine runs 3.2 @ 1.475V, OCCT 1hr. stable. But to last longer than that I need 1.5V, but it runs to hot for my tastes with those V's.
I have yet to BSOD during my daily tasks with 1.475 though

If I had some WC I bet I can stablise @ 3.4GHZ, Only if..

 

[kenkickr]

I did try 3.4Ghz @ 1.5v but system would BSOD right after the Vista loading screen. I am simply amazed @ the cooling power of the CM 600 heatsink I'm using. The max temp I saw running 3.2Ghz @ 1.465 was 45 Celcius!

Wow dude those temps are insane
Are those under stress testing or gaming and such?

I load around 60-61C after an hour of OCCT, but max with hardcore gaming for a few hours is the low 50C's.

 

[kenkickr]

That was just running AMD stability test for 30min. I'll try OCCT tonight and report to ya what I get if interested.

You know I never tried AMD stability test, i'll check that out as well

man I wish I can be playing with the 9950. You guys posting this are making me jealous. THe brand new board I bought for it died after like 4 days . Now I gotta send it out for RMA. S**T

The DFI died on you? That sucks man, I was wondering why you werent posting up anything up about your 9950.

As far as that AMD stability test goes its pretty sweet, i'm currently 40minutes stable at
3.3 GHz x16.5 @ 1.5V. THat doesnt fly with OCCT but, hey who cares.
If it runs 2hrs without crashing i'm keeping these clocks 24/7.

BTW I have 2 more 60mm fans pushing thru my HS so temps dont hit anything over 57C loaded. Custom cooling FTW

Here's the screenie of the temps, its amazing how the temps dont budge. You guys think the Voltage is cool? Looks like this board has lots of VDroop, its set a 1.5V in bios but CpuZ shows between 1.504 and 1.52V.

well there you have it, didnt even push it hard, hopefully I get it back soon bro.

 

[kenkickr]

Now I'm gonna have to play some more Sage! I just can't see a reason to upgrade to a Phenom II, besides the cache, when are OC's are so close...yet so far away!

That sucks Patty. I was in your boat pretty much all last year with the M3A32MVP, I swore I wouldn't get another asus but look at my sig...:shadedshu

 

[3dsage]

Yeah dude, I thought I maxed it out already. If I can figure out a way to get it to 3.4GHZ stable I'll be golden

Its true man,
the way I see it we are just 200mhz behind the p2's. So if i'm at 3.3ghz its like having a PII at 3.1GHZ

KILL IT, KILL IT J/K Sage

KILL IT, KILL IT J/K Sage

I think subconciously I am trying to. So I can buy me a PII
