1month+HEhee+ Brutal 1.56volts+ CPUvid/NBvid on 9x50 using Water/ High end Air

[gOtVoltage]

Ok unlike B2' the 9x50's B3's are Very much like the X2 65nm little brothers ( F3's) when it comes to VOLTAGE..

After long ,,long ,,Long ,,periods of High Volts and Beer (4me)to both the CPUVID and NBVID on CPU ,,Ive truely found that these chips Function past my expectation . They do Extremely good with decent cooling while using HighVids...

The only two Cons besides the type of cooling i can think of ,,

(It WILL BE HARDER to Oc a NON BE because of the CPU multi options).

( You may need to hunt down the Best Bios for your Mobo)

Non BE's will not be able to raise the Multi's above stock..How ever You can lower them..You may not be able to get the Highest Oc you would like . It all depends if FSB dosnt want go above 240/250..I know geese thatwould suck,,but some Mobo's just wont do it,, even good Mobo's ..My 9600BE still did 270+ using a 9xCpu multi on this same Mobo. I also went trough several Bioses trying out my HIGH VID method.. Some work better than others but all gave me the Same Volt options pretty much..I stuck with the Bios that Gave me the HIGHEST HT/FSB possiable...

Ive always seen the likes of,,

Why cant my NB go higher,,

this is the best i can do,,

I hate this one,,
My CPU stops at 2.8ghz and the HT dosnt move//wont go Higher?


Reading and Reading thus some more reading ,,led me to take the time and test variouse CPUvids and NBvids with my cheap @$$Mobo....Using a 9600BE and 9950BE i managed 270fsb with 9600 and nice 288fsb with 9950 ..I also found that B2's are not Volt friendly on the NB/Imc No harm done . On the other hand the B3's WOw,,take the Volts amazinly well. So heres what ive found..



Keep your Volts to what makes you feel Safe ,,raise them equally,,use +vcore after finding the VIDS that work best

How i did this ,,

WITHOUT overclocking i slowly raised my CPUvid and NBvid to 1.56volts + ..Keeping a keen eye on temps . Once i reached 1.56volts the Chip was still amazingly cool with my water setup in sig. CPU and NB volts should be raised practically the same/ = to each other/..

As long as my temps stayed in good order i would keep raising the Vids untill Everest showed a slowdown in the L! and L3 caches..this happened @ 1.65volts for me/..NOT for the Faint of Heart trust me,,Also this was likely due to my PWM's heating up on the TA770

Note:
( ive decided to not exceed 1.61v no matter what because of the PWM's,, i dont know how high these chips truely can Go Volt wise)

((1.55vid for Both CPU/NB = 1.56volts ))would be my Sweet spot before i DID ANY Overclocking at all...

Next ,,
I turned my attention to the SB/NB volts for the motherboard which after researching many Voltage setting from variouse 770/790/sb600 Mobos ,, i decided to stick with 1.31voltsSB/NB(controls the memory on Mobo and 1.27v for the HT@stock fsb200.( You will need to raise HTvolts to 1.31v-1.32v if you decide to Oc the HT and be stable ,, A Fan for HTheatsink comes in handy too)

Now that you have set the SB/NB/HTvolts turn your attention to the RAM..
Set the Recomended Volts for your Ram and manually set 2T timing with most settings on auto or set Your Ram specs only tweak the four primary Ram settings( Example 5-5-5-18 ). In order to find your Max CPU freqency i recomend to use lowest memory divider that your Mobo can run @ 2T (usually 400//533..)

Finally with the Ram set,, Try Overclocking your FSB until you cant boot past the Load up screen...When this happens usually the HT and OR NB needs to be lowered from 1800mhz to 1600mhz or 2000mhz to 1800mhz ..this depends on the 9x50 you have.

You will keep doing this untill you reach you max FSB//HT limit..( Average is around 250fsb with your final HT around 1800/2000mhz..) You may also have to Lower or use a different CPU/multi that lets you raise the CPU freqency or FSB..Some multis work a lot better than others...Also sometimes the Ram divider may need to be set to 533 instead of 400 and so forth..Every mobo is different. There wil always be a slightly different combination for every mobo that works. Even if two of the same Mobo's and CPU's are used!

Using the Above method you should be able to start Raising that HT and CPU fsb/freqency above 210 most easilly on just about any Mobo.. Even My M2N32deluxe handled 240fsb with a crap 9600BE using a 11.5 or lower multi and Stock Heatsink @2500mhz//2400mhznb..While using 1.5volts for both CPUand NB..Yes it runs a little hot with Stock heatsink..A blowdryer set to High Runs cooler than a stock heatsink,,Hahahaa.

Back to CPUVoltages for one last time ,, CPUvid and NBvid...
Each CPU and the Cooling each individual uses will vary and you must take that into consideration.. If your Chip is hot with stock cooling and Stock Clocks with Stock vids dont attemp Overclocking Too the hilt untill you get better than STOCKcooling or figure out why its running Hot Period..

I dont know as much as i wish with Phenom yet ,, but i do hope this does help some of you in regards of what ive found while MAXING my CPU to the Extreme Limits with out using Ln2 or Dice..

Note:
Before i messed around with my Vids it was pretty diffacult to get a decent HT/fsb with my 9950 using stock Volts CPU/Nb@1.3v

I only use water or high end Air ,,Thus i am an average Joe








Example of My Bios Settings,,

CPUvid(00) = 1.55volts NBvid(00) = 1.55volts ,,

I only Add +vcore when needed..I currently keep My system @ 3450//2660nb 203fsb//HT2060 24/7 @ 1.56volts because of SUMMER HEAT..

L@@K overall Oc,, NBfid @2000 = 2680mhz with 268fsb.. My HTfreqency is also set to 2000 = 2680x2 = 5360HT



P.S.
The Actual Volts used in Screens Are really what is shown!
When maxing All the Variables i listed above ,,it trually pushed My Mobos limits....I have to Wait untill End September before i can Order The Goodies ive put on hold ..Then i can see whats left in the same old 9950 but in a NEW GX/FXsb750 mobo...No my Mobo didnt Croak im typing from it at 3450mhz .My kitchen Remodel is far more important for now,, I really cant BBQ every night anymore for dinner..Hehee my California Hot Summer is coming to a close ,,gotta get her done

Happy Overclocking all,,

thanks for the post.. hope people make use of it and see how it goes for them...looking forward

I've been very afraid to play with voltages though my 9950BE appears to run fairly cool on air (27-30 idle/40-45 load). I've never been clear on what other voltages need to be raised other then the CPU/RAM voltage, so you're post is quite helpful. Can you break down what the variuos voltages are for? Here's the options I get in AOD (I'll look in the bios later because I know there's more).

3.5GHz nice! Is it prime stable?

Here's the options I get in AOD (I'll look in the bios later because I know there's more).

CPU VID
NB VID
NB Voltage

CPU VID,,
is your CPUvoltage,, which is predetermined by default in the MOBO's Bios Section along with NBvid and SB/NBvoltage..You can usually change CPU Vid option up to a Max of 1.55volts...

Note: (CPU +vcore or extra Vcore) is usually present with CPUvid setting in your Bios..

NB VID ,,
acts exactly the same as CPUvid but of coarse for the on Chip/CPU Northbridge..This also has a max of usually 1.55volts .The Higher the Volts the higher MHZ you will reach vs stock on NB,, You will also increase the CPU's heat output raising this just like how CPUvid does..Ive raised Both the same to push my chip to the max..You should keep them close together for stability.9950 is 1.31v CPUvid and 1.31v NBvid @STOCK/Default.

Remeber you have 4Xcores +NBcore = 5cores.. All produce heat when adding Volts..These new chips do like Volts when being cooled decent. Stability is easier when i Raise Both VIDS the Same amount when Going For Max CPU/NB...When i think about it 1.56volts for x5cores is lmpresive compared to the same volts on a X2.. Ive also noticed that if NBvid is set higher than CPUvid it will set the CPUvid a setting higher than the NBvid by default..This is normal with all Phenom/Bios code..Just the way the VID's works . I thank Polygon alot who realy open my eyes to Phenom.

NBvoltage ,,
is usually the NB on the MOBO..NorthBridge for the RAM to CPUNB..This usually stays around 1.15v-1.20vStock and 1.31v-1.35volts when overclocking with lots of RAM..More Sticks and GIGS equals little more volts here to keep Ram talking to CPU. I use 1.33v when i go for Tight Timing and or High Freqency Ram speeds.. Each Mobo will use more or less.

3.5GHz nice! Is it prime stable?

Yes with explanation,,CPU//RAM Prime Stable ... I have is the Origanal TA770 and Not 9950 OVERCLOCKING friendly at high of Freqencies...I made this work and i knew i would max My PWM's . The Most Ive primed has been 6hours @ 1.56volts 3450//2680nb//5300ht.. That seemed to be the Mobos sweetspot .. The One that breaks the camels back is when i aproach 3hours @3.5ghz but with lower NB/ht settings... PWMS work too hard and when they Start Sqeeling and sounding like bacon Frying i Stop prime I know ,, im not nice to my hardware hahaaa ..


OFF topic,,
Whats amazing is when i Play Crysis @3450 and with my 3870x2 cranking the pixels my CPU dosnt even sweat...Its nice to net 30fps + in 1280x1024 everything MAXED using One Card on a single PCi-E mobo...

XP32bit SP3 with ALIENware GUI,, my budget Vista J/K

3,45ghz prime stable is IMPRESSIVE using a 770/600 mobo !!

[gOtVoltage]

Trust me i almost gave in to Intel when i had a low Clocking 9600BE after being with AMD since they were born. It was truely the one time i felt like throwing in the towel..i know others have felt the same...

After learning How to tweak the TA770 Bios with 9600BE with many bugsOMG (not so good 4me CPU) I waited for B3,,So now My 9750brother build and 9850cousins build and my9950 are very happy campers. Ive become used to the whole Ht thing and bla bla bla Sb600 and unoptimized bios swaps and fubared AOD this and that..

I actually like the whole AMD challenge ,,I am not disapointed , i stuck it out ..I just wish they got thier together sooner..Funny i always owned a AMD/Nvidia system until this TA 770.. I finally went ALL in after 10years of AMD/nvidia ..Haa coupling this TA770 with 3870x2 was actually kinda foolish at first,, i thought ,, i then realized what could be Sqeezed out of it

[soundood]

let me start by saying that is a cracking clock you got there,

i am really interested in the PWM temps you got from the board, its just i had my AX78 running at 1.55v vcore, and the temps went through the roof.

under load they were hitting 80- 90 degrees C,

even i know that this would be cool for around a week or so maybe, and then the board would have probaly started the random shut off thing.

thinking on that, what would you say the Max temp for the pwm would be? i allways thought that it would be around 75 degrees C, before damage would occur.

FYI: i have fan cooling the PWM, and watercooling on northbridge and CPU, and to be honest the water is redundant, i could easily get this clock on air.

would be nice to make use of it with some high temps to cool , and we are coming into winter here, so i would allways push a little further.

but no matter what i do here, i cant get past 3 gig stable, even that is a push, i run 2.8 gig most of the time.

off topic: Crysis, hell yeah, i have the benchmark tool, but use the console tool to gauge FPS in multiplayer, its just better for me to gauge performance. i get 35 fps average on my 9600gt @ 760 core/1011 mem and my Phenom @ 2.8 gig, dropping to maybe 20 fps when two or three nukes go off

[Jaivan]

What kind of temps are you getting under load?

I'm under water too, with CPU/NB at 1.525v getting ~49C running BOINC.

Also just curious what the max 24/7 temps you run your chip at?

[Titan7171]

This is great info I have never gone that high on the voltages for HT or NBvid and am in the process of trying them out now. One thing I have had a problem with is the different performance I have gotten out of this MSI K9a2 Platinum and my 6400X2 BE and my Phenom 9950BE.

When I had the 6400BE in I got my fsb/nb and memory up to 280 1/1 on this mobo max and 270 for 24/7 settings.

Now with this Phenom I have not been able to boot at 250, I never messed with those high voltages though and usually just left them at auto or around 1.175 not knowing exactly what they did or how much they could take since I didnt mess with them for the 6400 why would I have to mess with them for the phenom? right??.......but we are dealing with 4 cores instead of just 2 so your info helps to make more sense of it.

Also through reading this post I also noticed another mistake I was making, In the section of memory timings I just noticed that there are settings for each stick of memory. I didnt realize that until today when I went in it had the option called "both" When I set that there were many more settings than I had realized. I have been only setting one stick of memory timings and leaving the other on auto this may have been causing an additional problem for me also.

Although I have been doing excelent with my results from my eyes there is always room for improvement and this post has helped me learn a little more. thanks and excellent post

Do you find that increasing the NB's vCore is essential to obtaining higher frequencies with the general CPU cores even when the NB isn't clocked higher? Do you get better results when the NB frequency is increased along with clockspeed?

He H had a similar situation with my first 9600BE in the DFI/Sapphire 790FX mobo at 2.9GHz. It required 2.4GHz nb to be stable and immediately froze with 2.2 or 2.0GHz. Longer testings however showed that this setup also was unstable it just failed prime later 3-4hrs instead of minutes.
You seem to use an PSU with more than 18A for the 12V rail, because otherwise your PSU should power off due too that limit been exceeded. On the M3A with an single 12V rail I found at 3GHz >1.45V the cpu pulled ~19W from the psu and powered of short after. May I ask what limit your PSU has for the 4pin 12V rail?

EDIT: You know you made me run prime95 with 3.2GHz/1.625V 2.4GHZ/1.5V for stability testing.

I have Zalman Ramsinks on my PWMS..They get screaming Hot when i Prime with Volts above 1.61v.. this Mobo i intended to be my trial and error Mobo..Since the first 770's had tha massive Pwm problems i went with a Biostar ,,TA770 was one of the few at the time that wasnt failing with Oced 9850 when primed up to say 2.8ghz..So i decided to push it.

Im @ 54c with 3450 @ 1.56v for both CPU and NB...I have to wait till end of September to finish up this little study with Max Vids...This Mobo just cant handle the CPU .. I did manage to pull some interesting results though

The whole X2 vs X4 thing is a give in.. This Mobo i can run 317+ with my X2 and Only 288Max with phenom.. I really believe these chips are designed for AM3/HT and are bandaided on any AM2/AM2+ even the new GX'x 790's the HT acts the Same with Bioses. I feel that the Bioses Should be made Exclusive for Phenom with a dual boot option if you need to throw in a x2 for trouble shooting.

Nb volts stabilizes the CPU better when it starts cranking .. Low CPU/Nbvolts is only good up to say 3.2/with 2400mhz or higher NB for me at least running stock vcore.. Just like X2's using default volts only let the CPU do so much..Im not insane so When im not deciding on using High HT i just settle for 3450/2660 with 1.56volts both CPU/Nb .

I also keep the (moboSB/nbvolts @ 1.31v--when set to 1.33v = droop) and HTvolts a little higher than stock @ 1.325 --when set to 1.35v = droop too. If you look @ my Bios screen post above.. Th CPU voltage first line is wher i would add extra volts if needed..I usually leave this on AUTO 24/7 with using Hexadecimal (00) = 1.56v for the CPU and NB on CPU ..Both get 1.56v

Do you find that increasing the NB's vCore is essential to obtaining higher frequencies with the general CPU cores even when the NB isn't clocked higher? Do you get better results when the NB frequency is increased along with clockspeed?

When it comes down to performance and Benching and Gaming and even when using more than 2gigs of Ram ,,Yes

..Remeber that i am using Water and @ Idle with 3450@1.56v im nice and cool @ 29c Idle and 54c Loaded After my loop is @room temp 26c.. High end Air is very simalar..

He H had a similar situation with my first 9600BE in the DFI/Sapphire 790FX mobo at 2.9GHz. It required 2.4GHz nb to be stable and immediately froze with 2.2 or 2.0GHz. Longer testings however showed that this setup also was unstable it just failed prime later 3-4hrs instead of minutes.
You seem to use an PSU with more than 18A for the 12V rail, because otherwise your PSU should power off due too that limit been exceeded.
May I ask what limit your PSU has for the 4pin 12V rail?

I can set my NB2400@1.31v up to 2680mhz my NB max@1.55v ...I can run that speed @ 2600ghzCpu/2600mhzNb ...Multi to 17x and 204ht 2660Nb or even HT and NB @268 ..I does almost any multi up to 17.5x then my HT only needs a few mhz to crank the NB anyway. Past 3.5/2580 requires 1.61vCPU and 1.55vNb .I have screens of 3.55ghz/ but the mobo will cook if i keep going. Prime would instantly start cooking Mobo at 3.55/NB+ speed with the volts needed pushes the PWMs too hard...

Now this is why im gonna get a better Mobo soon. Hm a 790GX/sb750 Biostar and im patently waiting for possiable DFI790FX/sb750..I want to order my goodies at the same time so i pushed backed my purchases to End of Sept. In case a real wicked Mobo comes out and prices should drop a few more bucks for another 9950(125watt to 140watt) so i can push that too and compare,, I know...

Hmm my +12volt is 52A budget ThermalTake 650.. Oh yeah it also cranks my sytem (11x120's 88cfm and 655 that i redrilled and then my 3870x2(stock Air to 918/200 while CPU@ 3450 eating up all my games)

Now @ 3450mhz and 3.55ghz My Supi 1M is still 22.5's-22.7's..Its so smooth i dont need more than 3450,, there is a noticable differance between 3.0 and 3.4,, Huge

P.s hope i got that covered.

[Particle]

As clarification, which question is true (of mine)? Does voltage need to be increased but NB frequency left alone or does both NB voltage and frequency need to go up in order for the CPU cores to clock higher?

[justapost]

I can set my NB2400@1.31v up to 2680mhz my NB max@1.55v ...I can run that speed @ 2600ghzCpu/2600mhzNb ...Multi to 17x and 204ht 2660Nb or even HT and NB @268 ..I does almost any multi up to 17.5x then my HT only needs a few mhz to crank the NB anyway. Past 3.5/2580 requires 1.61vCPU and 1.55vNb .I have screens of 3.55ghz/ but the mobo will cook if i keep going. Prime would instantly start cooking Mobo at 3.55/NB+ speed with the volts needed pushes the PWMs too hard...

Have not tested nb that much here. I applied 1.625V by accident with aod on the first day i got the gbt790gx. Surprisingly it worked fine and the system is max benchable at 3.45GHz. But to be prime95 stable i need >1.5V at 3.1GHz. BTW 3.2GHz failed on core 4 after a few minutes with 1.625V and immediate on core 1 with 1.675V (bios) 1.7 (everest/cpu-z). Seems my cores 1 and 2 don't like high voltages whom core 3 and 4 would require. I'll check the max voltage the cpu can take at 3.1GHz now. BTW the board has an third not labeld sensors whom does not show up in GBT's easytune. It seems to be a sensor in the pwm area. Without a fan there I get 78°C while running prime95 at 3.1GHZ/1.625V. With a fan ~64°C.
Tried 13x for the NB with 1.625V and the system booted, i managed to save a cpu-z verification file but the website does not show the nb speed. System ran with an 203MHz ref HT (200 in bios) so the real NB speed was ~2640MHz. Might get 2.6GHz stable hat the cpu running at 3.45GHz with 1.625V that caused a freeze during a wPrime run.

Now this is why im gonna get a better Mobo soon. Hm a 790GX/sb750 Biostar and im patently waiting for possiable DFI790FX/sb750..I want to order my goodies at the same time so i pushed backed my purchases to End of Sept. In case a real wicked Mobo comes out and prices should drop a few more bucks for another 9950(125watt to 140watt) so i can push that too and compare,, I know...

With denebs delayed i might also pick an 9950BE 125W. I also plan to get the AsRock and Jetway 790GX boards, both have 2x12V connectors. I'm unsure about an 790FX/sb750 board, I might grab an DFI one, but I'll wait for user reports here first.

Hmm my +12volt is 52A budget ThermalTake 650.. Oh yeah it also cranks my sytem (11x120's 88cfm and 655 that i redrilled and then my 3870x2(stock Air to 918/200 while CPU@ 3450 eating up all my games)

Looking at the PSU's datasheet, that limit is for all four 12V rails. It's 18A for a single one.

Now @ 3450mhz and 3.55ghz My Supi 1M is still 22.5's-22.7's..Its so smooth i dont need more than 3450,, there is a noticable differance between 3.0 and 3.4,, Huge
P.s hope i got that covered.

Have tried wPrime?

[Titan7171]

Well after testing up to 1.54v on the ht and nb its still a no go I got it to boot at 250 but I get a windows error "missing file" messege. The only thing I can think of is its my memory.....but it ran at 270-to 280? I dont know what changes it goes through using Phenom? and the next problem is temps....it was pretty hot here and I had the AC off I was idling at 42c right off the bat so for now Im still where I am.

[SocketMan]

You finally confessed hey?

Do you think that Polygon's BIOS has a lot to do with your success?
What do you think of the Biostar's mobo line up atm?

[gOtVoltage]

3450 with prime is 6hr before the PWMs cant take any more and 3.55 cooks them.. @ 1.62+

From what i can tell the weak link are the PWM's and amount of phases to transerfer the volt switching.

The pwms on first gen mobos 770/790 usually were of a lessor grade than what is now used..Remeber the FRYING PWM Failures with 9850 on ASUS//GIGABYTE//MSI when it was released...Most 770's use 3phase power IE/TA770/Se+ and a lessor grade pwm . Thus cant handle the pain i unleash

Biostars 790GX has 4phase with three PWM's per Phase vs 3phase TA which is 4pwm's per phase.. Also GX has the extra coil will make a differance along with Newer higher rated pwm's ..Although ALL biostar GX mobos will need you to add Heatsinks they will handle what im doing a lot better.

If the BiostarGX3/solid caps is decent in price i may bite on it,, For now the #1 budget mobo im eying the Biostar 790gx. The reason im using Biostar is the Fact ((Polygon ))RebelsHaven ,,comes up with some nice Bios tweaks..If it wasnt for him i would of never pushed this TA770 this far period.


TA770 was great deal @$85 ,,Let me learn phenom



TA790GX look at the Sata ports but for $99bucks its a deal and full of Bios tweaks


790GX3 Solid Caps and better Sata and CMOS layout,,I like but the Egg dosnt have it listed yet. Patience is priceless ive learned .


I am also eying on DFI's flagship 790FX/Sb750 ,,Suppose to Release Mid Sept08


Note:
Anything over 1.62v reqiures better cooling than what i have now and i use two tripples with a 655 just for the CPU..vs Using only one Bix3..It seems to work to disapate the watts.The 9950 idles @26c-28c and never goes above 54c even @ 3450mhz. So i figure that extra amount of Volts needed will be pushin the Max of my rads once i get another Mobo.. I thought about 120.3's but thats Quadrouple money wise..Maybe a second pump may work too cycle the heat to rads ..Hahaa i can always run three tripple Bix3's

In comparison X4 9950 @ 3.45mhz with 1.56volts,, IDLE 26-28c load 54c

X2 6000+with @1.56v and 3.48ghz 23c idle 41c with a shaved IHS Same loop.



Im amazed at the article below,"Funny thing its with 9600BE and High Volts,,Wish my 9600BE did that!",,
""
""Qouted ANANDTECH in a Euro forum,,790FX/Sb750 FOxconn""

""In regards to our 9600BE testing to date, our results have been unusual to say the least. We easily took our CPU up to 3.1GHz on the Foxconn board, but we have not noticed any dramatic differences with ACC enabled. As we approached the 3.1GHz range, our voltage requirements were 1.4825V with ACC enabled and 1.525V without it enabled. However, no differences in core clock speeds were noted on this 790FX/SB750 equipped board at these voltage settings. It was not until we installed this CPU in our 790FX/SB600 board that we noticed a true clock speed difference as our CPU sample would not go above 2.8GHz with 1.525V on the core. We found it strange that ACC did not really affect our core clocks as it had on our B3 processors. So, either the SB750 chipset provided a boost (not likely, but who knows at this point) or it's the board/BIOS combination from Foxconn. We are still testing on other 790FX/SB600 boards to discover any differences, but so far it appears this CPU is hitting a 2.8GHz wall on the Gigabyte, MSI, and DFI boards

We decided to do one more test and that was to increase CPU core voltage to a maximum 1.575V (does that void the warranty?, editor - probably so) on the Foxconn board and see where that would take us with this CPU. With ACC disabled we hit 3.2GHz and thought that would be our limit based on earlier results. After some fine tuning of the cores with ACC enabled, we hit 3.33GHz as shown in the screenshot below. We would never run at this voltage on a 24/7 basis, but with the help of some serious cooling assistance from our CoolIT Systems Freezone Elite, we ended up with a platform that has been stable looping various tests for the past couple of days. That said, with the TLB fix enabled, performance has not been good so we are looking forward to what the results will be with the fix disabled.""


Ok back to reality ,,Regular Deionized purple Water is what i used and a 120ultra with some high CFM fans for shure will do
Wow dint know FREEZONE Elite would work so good on a B2,,Makes me wonder how chillin it was...but interesting enuff...Freezone may be a neat little toy,,but i like water or natuaral Air for 24/7 use...

Ive never seen this article untill now and it really makes me think what SB750 will do with a propperly tweaked Bios and 9950 compared to my TA770/SB600..I should at least be able to use less Volts and maybe sqeeze +100mhz on my current water( im dreaming)anyway which i would be very good in my book.

OK im playing catchup,, i cant type worth ----hang in there..

Hmm I've been a bit wary of taking voltages too high, so never gone to the realms of 1.55v, max I've ever tried is:

CPU Voltage = 1.525v
CPU-NB = 1.375v
CPU VDDA = 2.70v
HT = 1.40v
HT Core PCIE = 1.20v
NB PCIE PLL = 1.90v
SB Core = 1.28v
Vdimm = 2.10v

So maybe I'll try having a more equal CPU + CPU-NB Voltage and try getting a higher NB speed... max I've gotten so far is 2400Mhz NB and 2400Mhz HT using 240 HTT Ref and x10 NB Multi and HT Set at 2.0Ghz (x10)

I'll try some of these higher voltages later and see if it yields higher clocks.

I'm using water on the CPU only, with the stock Copper HSF's for the chipset that come with the M3A32-MVP mobo, with the added fan to the HSF sitting on on the PWM's and a 40mm fan on the NB Heatsink..

I'll try the following settings, but would appreciate if you can confirm I've understood things right....???

That is to get better stability at high clocks needs:

• CPU and CPU-NB Voltages to be HIGH and as close as possible with CPU temperature being the limiting factor.
  
• Higher the CPU Clocks the higher the NB clocks need to be for stability
  
• Higher NB Clocks need higher HT Clocks for stability.
  
• And all the above need high volts to achieve stability... at cost of high temps.

The voltage settings I'll try:

CPU Voltage = 1.55v
CPU-NB = 1.55v
CPU VDDA = 2.70v
HT = 1.40v
HT Core PCIE = 1.20v
NB PCIE PLL = 1.90v
SB Core = 1.28v
Vdimm = 2.10v

With other BIOS settings as follows:

CPU Multi = x15/x15.5/x16
CPU REF HTT = 200
NB Multi = x10
HT Speed = 2.0Ghz (x10)
RAM = DDR2-1066

For:

CPU @ 3.0Ghz/3.1Ghz/3.2Ghz
NB @ 2.0Ghz
HT @ 2.0Ghz
RAM @ 1066Mhz

and also

CPU Multi = x12/x12.5/x13
CPU REF HTT = 250
NB Multi = x10
HT Speed = 2.0Ghz (x10)
RAM = DDR2-800

For:

CPU @ 3.0Ghz/3.125Ghz/3.25Ghz
NB @ 2.5Ghz
HT @ 2.5Ghz
RAM @ 1000Mhz

Any suggestions before I go ahead and try these out....?? Other than the obvious of closely watching temps etc....

Thanks for the info, given me soemthing new to try.... and at this point I'll try anything..!!!!.LOL

[gOtVoltage]

As clarification, which question is true (of mine)? Does voltage need to be increased but NB frequency left alone or does both NB voltage and frequency need to go up in order for the CPU cores to clock higher?

CPUvid first while using stock NBfreqency.. Once i find that than i Raise the NBfreqency ,,when it crashes or wont prime...I Raise the NBvid ,, My out come is 1.55v for both @3450 stable..Stock volts on mine would only get me 2400nb and 1.4volts 2500bn and 1.55v 2680 max @3450mhz

Well after testing up to 1.54v on the ht and nb its still a no go I got it to boot at 250 but I get a windows error "missing file" messege. The only thing I can think of is its my memory.....but it ran at 270-to 280? I dont know what changes it goes through using Phenom? and the next problem is temps....it was pretty hot here and I had the AC off I was idling at 42c right off the bat so for now Im still where I am.

The HT volts should always stay 1.35v or lower( HT heatsink get kinda hot with no fan on it).. The HT only needs to raise some if the HT isnt stable..Again 250 is pretty good but the HT volts you ran was way too High!

Missing file could be Ram/Divider and or timing . The NB on the Mobo not the CPU should be around@ 1.31v or maybe lower depend on how many Gigs and Stick yor running..This Helps alot with Ram /CPU stability. Sometimes Even the wrong HT freqency in Bios may cause it even though you NB may be able to go pretty high...I always run the Ram at the lowest possiable speed and loose 5-5-5-18/ 2T or 5-6-6-18 @tuntill i have my CPU/NB tweaked.. Sometimes i even have to lower HT or NB speed to get that higher CPUclock

Heat are you using Air/water? if Air so the Nb volts i would use around 1.35/1.4 and TheNB may not go as high . You will need to adjust by what your temps allow.. Cooling is a big factor .. With Air i can run 3400mhz Max with 2500NB @1.55cpu and 1.39v Nb any more and it would start raising the temps..The NB will add heat quik the higher it goes.

You finally confessed hey?

Do you think that Polygon's BIOS has a lot to do with your success?
What do you think of the Biostar's mobo line up atm?

50/50.. The Bioses i used from him Disable ALL TLB tweaks and has the Hexidecimal CPUvid/NBvid CPUfid/NBfids..they are still close to what they are in stock form.. Ive tested over 100 versions up to recent 728bios..When i ran the 9600BE it was Max @2550/2400 on this Mobo with Same Bios..I put the 9950 in and said what the F and booted it @ 3.2ghz with 1.31default volts for both CPU and NB2000... i used just the CPU Multi at 16x and 1066 ram divider all on Auto with TLB disable fix for the first boot.

Compared to stock bioses ,,His gives better speed and Voltage settings . Even with the 9600BE i still ran @ 270fsb on this Mobo . Again using same Bios and even Same DOMINATOR rams. With both cpu's i tweaked the HT the same.. The Higher i raised the FSB/HT i had to lower the HTmulti and NB multi.. @ 260 id use a HT and NB 10x multi to get 2600mhz on the 9950 and with the 9600BE i would use 8xmulti for 2400 @ 260// 7x @ 270

Start off with CPUvid @ 1.55v record you temp stock clocks..

Then reboot and set NBvid to 1.34-1.35volts(this will be the CPU/NB).. Always Record temps .

Now with both voltages set "The compare the CPU temp to CPU/NB temp with both voltages) There should maybe be only a 2c diferance if that on Air. With My water there is no change..Always try to Clock CPU first using CPU multi if you have BE ..This will give you a ball park to aim for..Then give me a CPUZ and temp and well go from there.

Note: Try these settings for the MOBo's SB/NB HT volts this is what i run 24/7 "even when i had the 9600BE.".

Set Mobo Nb to 1.31volts if you plan to raise the HT.
Set the HTvolts or core to say 1.27- 1.31v .. Youshouldnt need any mor ehtan that.. Ht is usually good to 1.35v..

I have just stock heatsink on my rd780 and SB600 with just the Air in my case blowing across mobo.

Also maybe use Speed fan to monitor The mobo or CPU hW monitor...

The CPU factor is = to the goodness of your cooling.. better cooling better clocks...The Goal for Phenom 3.0 stable while kepping L3 performance up,, High NB is nice 2400-2600 will come with a little xtra heat ,, This is why i suggets starting with 1.35-1.4volts for the CPU/northbridge know as NBvid...

I knew what to expect ,, Some one had to push these things sooner or later.

My pet Phenom j/K i was like WTF howd that get there. He's back in the wild thanx to me..

[HondaGuy]

Just starting to play around with the FSB..Kazgirl running the same as you just NOT on water

[gOtVoltage]

Your ram is Screaming..are you using 1066divider still?

Well from the looks of it you should get 240/250 with 9xHT 9xNB..If your doing 2300 now on 10x.

This threads getting fun ....Thanx All



P.S

Ooooo PCi_E speed ,, Sometimes it can affect HT stability when going higher than 115-120. too much and card goes

Hi Sorry guys...

Had to go to the dentisit, had some major toothache, and ended up having to have it removed, lower right molar, and it was deep rooted, and now I can't think straight with the pain....so its not a good time to try messing with settings at the moment.

I'm going to try again later this week, hopefully when things have calmed down a bit.

I'll post some details later this week, but I'll keep an eye on the thread in the meantime in netween bathing my mouth with Corsodyl mouthwash.

Thanks for the tips, I'm definitely going to try them out when I feel more up to it.

[HondaGuy]

Yes the ram is still @ 1066
PCI-E has always been at 124, Ive never had any problems

you be careful girl and take it easy, i had a lower molar taken out recently and i had to take a week of work, peeps dont realise that it is a minor operation as such.

and also that you have a gaping wound on your body, that just plain exhausts you, god i never felt so tired

all operations need recovery time hope you feel better soon
