Thats great voltage for a stable 3ghz OC. congrats on a good chip. Mine on the other hand seems to thrive at higher volts. For 3ghz I need 1.34v for stability.
Been running abit higher than that benching though. Not sure about over all stability but have finished some 3D marks at 3.5ghz. After vantage and 06 runs my temps are still good. anyone else braving high voltage? Im running water btw.
3.5ghz @ 1.63v temps about 50c max after both runs.
Going to see if I can break my personal best at 1M sp 22.172s @ 3.6ghz

Don't you think your CPU score at that clock should be a bit higher? I score the same at 3.2 GHz, just asking bro, seems a bit low, you have any idea why???

Just a quick head up to those of you who have posted in this thread and have either assisted or been on the frontier of pushing the phenom CPU's
Thanks to your efforts I now have my CPU prime95 *stable* for over 3hrs (sometimes 9hrs) at 3.2Ghz, which was my goal when acquiring my CPU.
This is very much appreciated, without your guys here at XS, this would have proved a lot more time consuming!
:clap:
Now I wait for the Phenom II to appear to see what we can do next
:)
No problem bro, thats what we are here for dude. Glad you reached your goal, and I think we are all waiting for the Phenom II to arrive :)Quote:

Just watch your temps and ive found my NB uses at least 1.48volts for 2500mhz stable at any ram freqency. ..Just raise it slow and watch temps ,,youll see..
Also differnt ram multi will help with high NB..Some ram multis work better than others even if the Ram freqency is lower than what you had before. Even Mild latency like 5-5-5- with 15 or 18 is a phenon sweetspot indeed.
I always clock what the IMC likes most,,thus trying to have a Low latency above 800mhz it dosnt like too much.
I thought UNGANGED provides better perfomance..Quote:

Ive tested CPU/NB to the Max Volts Asus79-T Mobo has to offer.
Hello people. This is my 1st post here.
I recently got a Phenom 9950 BE 125W tdp CPU,
an ASUS M3A78-T motherboard
and a pair of GEIL B.Dragon 2x2GB 800MHz CL5 RAM.
I dropped them in my case (Lian Li 2x120mm,1x250mm side) with the stock cooler changing only the thermal compound with AS5.
I flashed the latest BIOS (502) and was ready to get busy.
I like to explore things on my own just reading stuff but this board is a bit weird...
So I came here thinking I might get some answers.
In the end I managed to get 3GHz (200x15@1.4V, ACC +4) with 60C (I think) peak load temp. And I'm stuck here.
Things I figured out so far and questions:
1. The mobo sets Vcore at 1.4V in auto even in stock speeds. eg when I clearcmos it defaults at 1.4V. The mystic thing is that you only can see this in the bios and pcprobe2. AOD and cpu-z show only the VID (whatever this is?) with a static value of 1.3V.
-Is this a bug or something? anyone with the same board /and cpu? Could it be the cpu is not recognized correctly?
2. If I change the CPU voltage in bios (I think it changes VID not Vcore) then AOD and cpu-z report the new static VID but thankfully the actual voltage changes (as reported in bios and pcprobe). And I managed to push 3GHz.
The funny thing was that I tried in AOD first (cpu vid=auto=1.4v actually) and thought woaaa 3GHz with stock voltage easy!When I got to the bios an set everything manual I bsoded.
-Why cpu-z (v1.48) shows VID and not core voltage that I see in other screenshots?Is it poor Bios support?Am I doing something wrong?And what is VID anyway? (guessing - its the reference value that the vcore should be.but then why vcore is 1.4 in reality with a 1.3V VID?)
3. Temperatures in programs seem off except in pcprobe2 that reports the correct values for voltages,fan rpm and temps (voltage seems correct as described above, fan speed numbers seem correct , temps seem to change in a normal manner as opposed to coretemp/speedfan and is proportional to fan speeds). Or the bios/pcprobe reads the wrong temps...
-Anyone knows which is the correct reading?mobo/probe or speedfan/coretemp?
4. While trying to go past 3GHz, I got to the bios and changed CPU NB voltage to 1.35V as some have suggested (while I only clock with multi so far, I thought it might help). Well the bios setting did absolutely nothing I think (actually changes CPU NB VID, I think). AOD reports the same CPU NB VID (1.2250V) no matter what I put in the bios. Also I can't change it from within AOD. I hit apply and it goes back to the default.
-How can I check if the setting works?
5. CPU tweak = AOD green button top right. I double checked this out of curiosity because when it had the red circe in AOD my idle temps were 5-10C higher! I didnt notice any change in load temps. So I was trying to figure out what this does and I noticed superpi was a bit faster with it enabled. I also read here later that some other people noticed this. Also, it has nothing to do with tlb fix, as I have read somewhere, and the mobo manual says there is another setting for the tlb fix (doesnt show up in mine.not applicable I guess)
-anyone knows what this is actually supposed to do?Is it documented anywhere?
6. Finally I would like to ask what are the max safe 24/7 vcore and temps.
I have Vcore at 1.4 and I am a bit concerned to go higher. Also, is it safe to go above 60C peak load temp?
I am currently trying for 3.2GHz but anything I have though ends in bsod with Prime.:confused: At least I managed 3GHz not so easilly after all.I had to give +4 ACC for 8h prime stable. I think its ok. (+4 ACC was my first try btw. Don't know if its the best)Cpu-Z validation
Thanks.
I hope there is someone with same mobo/cpu so we can at least check the bios stuff if they are the same.

below responses are matched to your post:
1- I trust CPU-Z over any other program as far as voltage. Have you tried to see in the BIOS what it is reading? Should tell you under hardware monitor. But i have a 140w tdp Phenom and the default vcore is 1.312v or 1.300v in the BIOS with my M3A79-T board.
2-dont know what to tell you bro, again check the bios under hardware monitor and see what it tells you
3-I'm not sure about your board, but with my board M3A79-T they have really buggy temp sensors. Mine displays 10ºc higher than everything else. For that reason I find the most accurate Core Temp and Hardware Monitor. However when I had my previous M3A32-MVP board that had sensors reading correctly, I found PC Probe to be the most accurate.
4- I would try to leave your NB voltages and SB voltages on auto for now, I can do all the way up to 3.4 GHz without touching those. However, try to clock with the BIOS, AOD changes things around and makes it confusing. There is a member in here named "got voltage" he can tell you exactly how it works with AOD, or I believe a few posts back you can find that info, great guy and has helped me alot.
5- CPU Tweak is basically a performance boost, however it does increase temps by easily 5-10ºc. I never run with it on as I don't think the performance difference is all that great in the real world use of the computer, higher temps for really no reason. However some have reported slightly higher stability at higher clocks with it on. However watch your temps as CPU tweak can help you just as it can hurt you (temp wise)
6-I have ran my Phenom at 1.63v under water and no more than 60ºc under full load. However you can set the voltages as far as your cooling will let it go. Always increase voltages one notch at a time, and don't go from 3.0 GHz to 3.2 GHz. Just try small increments at a time. It'll pay off an you'll remember me, everyone else can tell you too!!
Good luck and keep us posted dude!! :up:
@ xaris106
Here you go, the post I was talking about referring to response #4 on my post. Lots of useful info on how AOD works in conjunction with your BIOS. I just use the BIOS now, AOD only made it more complicated for me, it is however a great tool!
http://www.xtremesystems.org/Forums/...&postcount=492
thanks a lot.
although my mobo does not have seperate VID and vcore settings, I can see that aod can cause trouble when it reads wrong settings from the bios and I hit apply. basically when i change the multi to x16 to get 3.2GHz it might mess with the probably wrong cpu nb vid reading. Although it doesnt seem to change it. I dont really know. The bios seems a bit buggy to me. especially the wrong vcore auto setting (yes I check the bios for the real voltage.its the same with pcprobe)
The problem is i dont know if its the bios that doesnt set cpu nb or aod that cant read/set it.
Also for the cpu voltage. Isn't there a danger from high cpu voltage regardless of the temperature? thats what i'm asking. eg is 1.6V dangerous even with 30C temp at load?whats safe?
I'm trying to get the max 24/7 oc with the stock cooler(+AS5) and my current goal is 3.2GHz with minimum vcore (prime stable). Anything above 1.4V seems pushing it.or i could go a bit more? I`m at 60C now with 3GHz@1.4V. I mean I'd like 3.2G with 1.4Vcore so I`m trying stuff like cpu NB vid, unganged ram, acc etc but no luck so far.
Well of course too much v core is bad even with good temps. But I say 1.4v to 1.5v is fine for everyday use. Once you start going over 1.5 or close to 1.6v, its pushing it to me. Although it can last a while like that, you are definitely pushing it. Did you disable CPU tweak??Quote:

If you can get it to boot stable at 3Ghz with Bios, I would suggest that you leave it there and use AOD to turn it up until you find the stablility limit. That way, if it crashes you'll still have a good BIOS setting to reboot from without having to reset CMOS.
It seemed like a nice board, but early BIOS were really flakey....
Good Luck man, sorry I couldn't offer more help, I sold the board to a friend and it's happily running in a HTPC now... :cool:
Yeah I have it stable at 3GHz from bios (8h prime) and I use AOD with these settings as base to try for more, as you suggest. Didn't have to clearcmos even once so far.AOD is a nice tool for trying things out - not sure if some settings work though, with no feedback from another program, like in the cpu vnb setting. No luck so far above 3GHz. I can run spi 1M at 3.2GHz with the same settings as the stable 3GHz, but I bsod instantly when I start prime. Maybe I`ll try more Vcore or HTT and clock straight from the bios.Quote:

Anyone knows why cpu-z does not report core voltage?Maybe it doesnt support the mobo yet?
...Perhaps, but i dont`t think so...Have you ever tried the new version 1.49?Quote:

thanks though.
@ gOtVoltage
Hey dude, finally overcame my stability issues passed 3.2 GHz. This chip just wanted lots of more juice. The vcore in the screenshot is a bit higher than what it needs to be for my chip to be stable at this clock but thats just what I have it set at for now. Temps under full load go up to about 45ºc and vcore jumps to 1.6v!!!! Anyhow, idle temps and just browsing around and gaming stay in high 20ºs to mid 30º's max. I overcame the fear and just upped the damn voltage and now I got one happy Phenom :). I just wonder how long it'll stay happy, but with the AM2 Phenom II just around the corner, i'm not too worried as I am getting once released.
Anyhow, so far i've ran this chip like this at 3.33 GHz for about 1 week now or a bit more, done a few runs in prime for about 15-20 minutes each and never fails. So hasn't crashed once yet, benchmarked a lot with it and have gamed and just used it since, flawless so far. Guess Phenom is like "the perfect storm" :p:

Hey, if you wouldn't mind, would you edit your sig so we can see what parts you are using? If your using anything less than a 9950BE, 3.0Ghz may be the best you can get with your particular chip.. My 9850BE is pretty weak and takes way more V's than I'm comfortable with to go much over that.Quote:

I'm pretty sure this chip would do a little better than this with more V's, but I'm on air and my load temps hit 60c while running Linpack...
Speaking of Linpack, you might want to use that to test your OC's rather than long Prime runs... It stress's the system much harder, but doesn't require hours of stress to your Mobo's Power section (which tends to kill boards!:yepp:)...
Here's a link for the IntelBurnTest (Linpack), Thanks again to AgentGod ;)

seeing your @ 60c load on Air and the Volts arnt over 1.5v it should bring that Load to a 56-58c. Every Bit helps right:up:
let me know what ya think.. It wont enable TLBfix on B3 ...So you wont see a decrease in performance like with TLB..It will disable Optimal power and load states for CPU and bus..
'
Your before and after benches should practically be the same from what ive been seeing so far..Im now trying to figure How high i can sqeeze my 9950 with CPU tweak off
^^^ I found CPU Tweak only giving better performance in Super pi.
SO I turn it on, close AOD, run super pi, open AOD and turn it off hehehe.
Anywhere else, difference not noticeable.
^^^ it all depends on what and how you want to overclock ..I must say when its OFF the Bios reads temps like all the Other Mobos ive used..i believe this is whats causing ASUS 79-T to report Higher than Normal temps(Being Enabled)..
CPU tweak OFF (disabled )i am @ my Normal Temp for 1.65volts and 1.55vid for Both CPU and NB in which i ran on Four other Mobo's with this cooling..
CPU tweak is actually not needed and isnt implemented on a lot of Bioses for most midrange low end other Mobos..I dont see how ive missed this before. But im glad we caught on to it.
By not using this item you gain two good things (higher CPUclock and NB possiably ) Way lower temps. Depends on what each chip likes , It will help to have it Disabled if you have a chip that builds heat quik or uses High volts to clock.
Also i use AOD to monitor and thats really it.. i like to Oc Old school hands on in Bios:D
Hey Got, I have pretty much the same results as Chicken Patty... CPU Tweak only showed improvement on my SuperPi times, and like you the temps went up quite a bit compared to the performance boost it offered.Quote:

I'll try to run a few more benchies this weekend to see whats up, but my gut feeling tells me your right and the CPU Tweak option w/temps is better off left disabled. ;)
yeah same here. I have not tried auto express, but CPU tweak is no good for me.Quote:

Thanks.I`ll try that and see if it works.Quote:

Try running 3Dmark-06 for the full app with the cpu tweak on in AOD. IF I remenber right it was a 300 point pick up running the full app. for me .
Hi.I run some 3Dmark06 test,using cpu tweak on/off and find out pretty big differences.Cpu tweak on,i scored 15717 and cpu tweak off,i got 14841 points.I think that´s a big difference.

It has information and ideas throught it.
Got to say by looking at your temps Im not liking it........60c is unnacceptable for high clocks, it will not happen. Is this temp while running prime?? if so very good, or is this your idle temp that would make it very bad.
Cool cpu is key to good stable overclocks......especially if you want to be prime stable.....prime will murder your cpu and mobo with high temps. So get your cpu cool......and dont just buy a top of the line Heatsink and think this will do it........your case temps dictate everything, so if its 60c in your case your cpu will be 60c no matter how big your heatsink is. The fan will blow 60c air onto the heatsink and cpu.
Just a bit to think about:yepp:
thanks for the advice. I have read till page 12 so far. Its taking some time. 60*C is the peak after 30 mins of prime(4 threads). My idle is 37~38*C with cpu tweak off and 46*C with cpu tweak on.
I have run an 8h prime at these settings (1.4v, 3GHz), and played crysis a lot. I think its stable.
About case flow and temps, I think my case is ok (Lian Li mid tower, 1x120 front intake, 1x120 rear exhaust, 1x250 side intake, 1x120 psu exhaust, top 80mm hole no fan, some cable management)
I use the stock heatsink/fan with arctic silver 5. Also I have enabled pwm control for the cpu/case fans in [optimal] setting (asus) to lower noise in idle.
I`m not new to overclocking, I should menton. (my first was a celeron 466MHz that was happily running at 583MHz). I know the basics. I wanted some info about the particular cpu (and mobo if possible)
Is it ok to go above 60*C load temp?Whats the safe limit?and about voltage?is 1,45-1,5V safe for 24/7 operation?
Hi everyone.I have been playing with this cool chip for 3 to 4 days and its been fun overclocking this baby.:)
Till now I have managed to get CPU@3480Mhz 1.45v/NB@2400 1.35v. Idle/load temps are 29/57 *c,this setting is 24/7stable.I used 14.5x cpu multi , 10x NB Multi, Htt is @240. ;)
I am still playing with different setting to find out what can I achieve.MSI have limited max vcore to 1.45v in bios so it gets tough to get things stable above 3.52Ghz, and also keeping temps down is not easy without WC set-up.Here's a pic :p:

very nice clock ^^^^. You sure you can only do 1.45v? Maybe your board might have like a jumper where you switch pins and it allows for higher voltage???
Nop , the only jumpers are for some kind of bus overclocking that is no good.:( I mean it does work but only over clocks cpu from 2.6G to 3.1G without ACC on and no extra volatage , but thats it.
Titan7171 has the same mobo and I read his posts in this thread and found out if cpu vid is set to 1.45 along with cpu vddc to 1.45 in AOD , cpu-z shows cpu core volatge @1.496v as u can see in the pic above,that helped a lot in getting things stable above 3.4ghz.Thx to Titan7171 for this use full post. :up:
just giving it a shot :) Thanks dude.Quote:

There's a reason why they limit the voltage in BIO's to 1.45 though. The PWM section of the board is a little weak (I found out the hard way :rolleyes:), while the DRMos fets supply a really clean voltage, I don't think they can handle alot of power going through them.
Just a suggestion, if your going to run @ high v's remove the little aluminum cap from the FET cooler and put a fan blowing on the whole power section of the board. :up:
woot woot!!! lets go AMD
amazing!!!!!!!!!

Hey dude, thanks for giving me the shout out:up: Glad you got that cpu up there it seems that those 125watters are better than my 140 watter, I got one of the first availabe from newegg. Excellent overclock Blaber!Quote:

One thing I notice though is that alot of people are lowering their HT and nb frequency........Is anybody here thinking that having such a low HT and NB negates the 100-200mhz you are getting from the cpu??
OMG this is getting real good:yepp::up::DQuote:

well something in my system doesnt like the cold. I reinstalled amd od and got to 3.5ghz in the house so Im like ok prolly od was corrupt or something I stick my pc out the window again and Im watching temps drop when it hits 10.5c it froze up again......oh well:shrug:
^^^weird bro, wtf!!
Could you be having any sort of condensation?
Let me tell you about something that happened to me.
I was running fine at 3.3 Ghz, my daily setting. Stable, and all of the sudden comp kept restarting. Brought down the clock, still. Default settings, still. I was like WTF. I have my pump and reservoir mounted inside my drive bays. The hose going back to the res was leaking drop by drop and it was rolling down the front of the case and shorting with my front case fan!!!!
I cleaned up the mess and re attached the hose well into the end of the barb and tie wrapped it. issue fixed and that was my problem.
Maybe you were having any sort of moisture or condensation that you were not seeing? What do you think?
here is so you can have an example of my setup, cell phone pic so sorry about the quality. Luckily it didn't roll down onto my harddrives which are right below it!!!
You can see the tubes leading to the pump and the reservoir:

That's a really nice settup CP...
How did you get the PCI slot cooler mounted over the PWM Block?
Or am I missing something, and thats an aftermarket cooler...
Thanks Dave.Quote:

you clear now or did I miss something???
damn at least you found what the problem was, what Im thinking is that the psu was prolly cutting off because it was too cold? Its the only thing I could think, it was 4-5c If it was condensation the system prolly would have had the same problem when I brought it inside but it didnt.Quote:

Yup , the first thing that I did when I got this board was to get rid of that little aluminum cap from the FET cooler and put a fan blowing on the whole power section of the board (using the same words from your post :) ) : Pics:Quote:

@Titan7171 and MSI DKA790GX Platinum owners we can easily get a cvpu vcore of 1.54v by setting the voltages for CORE & LOGIC part of NB and CPU Properly in BIOS.Just check this pic:
http://img136.imageshack.us/img136/3...ture001pb3.jpg
These volts can be changed and you can definetly experiment a little more to find out how much volts you will end-up with on your board.Now after setting these volts in bios boot to windows and set CPU VID & CPU VDDC IN AOD to highest values and VOILA we have 1.54v as shown in CPU-Z.
http://img90.imageshack.us/img90/5852/155vbt0.jpg
Mind you AOD will not read voltages properly as it will report only 1.45 or some thing like that.
did that come with the motherboard? I noticed like a few sites had it and others didn't have it.Quote:

I'm not sure why they decided not to provide them with the M3A79-T though... but I have kept the ones I had with the M2N32-SLI, including a DOA M2N32-SLI I bought, and so had some spare...
So I just used the one from my M3A32-MVP mobo on the M3A79-T, and then used the spare one from the DOA M2N32-SLI, for the M3A32-MVP.
Though I did notice that it was a really tight fit to get the M2N32-SLI fan onto the HSF for the M3A32-MVP, and it actually bent a couple of the copper fins.. but nothing major...!!!!
Use the one that came with your M2n32slideluxe:D Its the same one he is using..Should clop right on:up:Quote:

Whats wierd is Vista dosnt like my Monitor Running DVI where Xp32bit was fine,,I even tried most Nvidia drivers and still it dosnt like DVI..But on XPsp3 it works fine with Same driver revisions:shrug:

Just a teaser.. Im going to try for 3.6 tonight. at 3.1 i was idleing at 23c >< i can see my breath in the office but hey.. Pain is gain right? :)))
More to come... hopefully ><

Hey ,,TITAN,,your running a 4850x2.. Did you Know that Raising the PCI-E lane watts to 200 will let you Overclock the 4850x2 to its max and keep it stable..
It will also take Stress off the CPU because the 4850x2 uses 290 to 300 watts when clocked or running full tilt..75watts on the Pci-E lane dosnt work good for X2series GX2series or GTX260/280..Ive testted this many time with friends cards that ive tweaked for them.
In the Bios the PCI-E setting Menu to enable Multi graphics Press F4 and #2 and #10 are the PCI-e lanes that are 16x slots ..
Set to AUTONONIMOUS and 16x and 200 for #2 and #10 it may be elen ..All other slots keep on Auto...My 3870x2 uses 255 to get 920/2200 on Air while @3.52ghz
I just installed a GTX260 that didnt like to run @3.5ghzcpu..The problem was the PCI-E lane Did not have enuff watts to let it run while my CPU was taking all the power...So again i changed the 16x lanes from 75(75watts) to 200(200watts)
Walla My GTX is now Stable @ 3.52ghzCPU ...
I forgot about Raising the PCI-E lane watts when the CPU goes above 3.4ghz .
this is the Same way i was able to overclock SB600 @3.5 with 3870x2 and 8800GTS(G92)@950/2300/2300.. When you dont have enuff Watts on the PCI-e lane the Card will shut you down after a while or you wont have Driver stability while trying to Overclock HIGH.
Last About the Cold weather and wierd OC.. set your VDD to max 2.8v and use at least 1.5v for both CPU and NB.. Only Raise the CPU Above 1.5v with out ACC.. it should keep the CPU warm enuff to Hit 3.5 but cold enuff to stay stable..The extra Cold Needs Volts for Phenom NB so it dosnt stay too cold..
I.. Usually use less volts with Cold which usually is better but , phenom is odd to oc with cold. Im amazed how Phenom actually Likes some type of heat even when Cold..
I hope you get that 3.5ghz-3.6ghz+ your looking for..
Hmm ya Know it works warm,, So i suspect you need more heat in the Kitchen to thaw @boot..making the NB1.5 will be like a EngineBlanket.. it should keep CPU warm but not too cold while it is Outdoors..
Nice run there :up:. Just wondering if you have updated to the new BIOS for that board? If so, then were you aboe to hit the3.5-3.6 mark? 1406 bios here seems to be more stable. Also when I updated my BIOS now in Everest it says that my board supports DDR3 Ram... I have circled it in Everest.Quote:

Have Not tried the new BIOS i might actually go do that right now. But something is blocking me at around 3550 ish MHZ. Windows will just lock and im afraid to throw anymore volts at it. I was up to 1.50 and thats as high as ive had this chip. The temps were fine... say 27c to 39c under load but still acted funny.
Anyways going to flash this new bios in and see what happens!:up:
Yeah I agree they are distracting me and forcing my hand in settting up a WC loopQuote:

NB Frequency: 236 HTT x 10 = 2360mhz
HT Frequency: 236 HTT x 10 = 2360mhz
Mem Frequency: 236 HTT with 800mhx boot strap (i.e. 0.50 ratio) = 472mhz
Ive attached an excel sheet I made regarding Phenom overclocking that I use to calculate the numbers etc, if anyone has the chance can they check this is correct as I am stumped as how you are getting these settings.
Maybe I am missing something big in the bios of my motherboard
:confused:
Or my maths skills are just terrible
:p:
-- EDIT --
Oh and can peeps post there settings in this thread in the format ive put above, if possible
i.e.
CPU Frequency: 236 HTT x 14 = 3304mhz
NB Frequency: 236 HTT x 10 = 2360mhz
HT Frequency: 236 HTT x 10 = 2360mhz
Mem Frequency: 236 HTT with 800mhx boot strap (i.e. 0.50 ratio) = 472mhz
hey thanks for the info, one thing that I noticed is I was overclocking the 4850X2 yesterday with AMD gpu clock tool and I was actually getting lower scores as I passed my overclocks that I was doing in CCC. In CCC i got the gpu cores to 700mhz so I figured out how to use AMDgputool (had to run it as administrator) and first oc to 715mhz then 725 mhz but my score was going down instead of up! So I gave up and stopped. Is the voltage the cause?? As for wattage is that total system power or just the GC?? now you got to know how bad my HD2900XT had to be and they say it pulled 315+ while benchmarking load and I never had a problem.Quote:

Hey Guys, Tried the new Bios... Very Impressed.
I went from 3.4 Stable at 1.4volts to 3.4 PRIME STABLE at 1.35 volts. Also raised my normal operating clock to 3.2 ghz at 1.325 volts on both the NB and the VCore.
Im a little sad that i cant seem to push past 3.5ghz. My temps are good and my Chip is good i just cant seem to get a stable run at 3.5 or 3.6. It could be my older board but i just dont think thats the case. Im thinking i need to manually tweak every voltage and give everything just little bit more. Something most interesting though is my OCZ Reaper will not Boot when i set it to 2.1volts. It wont boot on anything other then Auto. Very strange but meh. When i check the volts it tells me its running at 1.8 volts wich is Wayyy under what its rated for. 1.9 i could see but 1.8 seems too low. But the ram timings are Tight at 1066. 5 5 5 15 26. Another weird issue that i have is the Clock skews are never the same.. One will set to Delay 350 and the other will set to Delay 400.. I have no idea what this means :P But i just reset them both to normal and leave it alone.
But all in the 140* (cant remember the last number im at work right now and to lazy to go look ><) BIOS for the M3A32 Delux seems stable and helped lower my temps and Volts required by a fairly significant amount!
I have the same board as you just with 9850, 1406 bios is much more stable, I like it also. You should be able to tweak more settings in the bios in order to get 3.5... Just make sure that you have your RAM set to UNganged, you will get better Overclocks.
Just "Squeezed Out" some more Mhz last Night..Still having lots of fun with that µATX Setup....:D..
