I dont have that problem though.

Is anyone else getting higher then normal thermal reading with this board...? with out CPU tweak on? I use the same chip, same water cooling, swap the board and 8*c cooler. Swap board back to the ASUS, and 8*C higher... Is it just me or what.. By the way, setting are the exact same on both boards.
what are you using to read the temps? The M3A79-T has buggy sensors.
I use Core Temp and I get temps about 10šc lower than in the bios and pc probe.
Also AOD, HW monitor and every other programs registers the same as core temp. But PC Probe and the BIOS report way higher temps.
Yup,, it reads the Temps higher than normal or any other Mobo ive used so far 770/790gx/790fxsb600/790FX750..It seems ASUS 79-T reads about 8-10c higher across the Board in Bios and in Windows.
Note:@ 22c room abiant temp
All other Mobos @ 1.55vid with 1.65volts for both NB and CPU ive always been @ 26c Idle..
The ASUS 79-T puts me @32c Idle @ 1.55vid and 1.65volts for both NB/CPU.
Same Watercooling was used for all of my Mobos. Ive even tried my 6000+ which also reads about 8c higher..So its a Mobo Bios issue indeed:yepp:
Sometimes with ACC on +4 or +2 it would lower the temp some but never below 30c idle on my 9950(140watt)@3.5ghz
here are my bios screens:

also, why can i only choose 1.6GHz as max HT link?
Thanks for the screenshots.
As far as 1.6 GHz for the HT is because your NB multiplier is at x8. The ht should never be higher than your NB so its setup like that to prevent that from happening.
If you lower your FSB and higher your multiplier you can set your NB at 10x and set your HT at 2.0 :)
Take CPU tweak off by the way, that gives you wayyyy higher temps. You can also try disabling CPU prefetching and see if that has anything to do with it.
what's with the clock skew thing mine says 300 on both what bout everyone else ?
that skew thing is one strange thing...
at default (auto) with htt at 200mhz itīs like in the screenshot. but when i raise the htt it defaults to delay 300ps for both banks. when i leave it on auto i get no post. i have to manually set it to 300/150
@chickenpatty: oh.. damn.. i forgot about the nb/ht relation ;)
Interesting, took that off and the temps really falled down in idle like 5C, now idling at 39C :D Load seems to have 3-4C lower temps too.
What does this do? Some pages says its like tbl fix on and other pages says it lowers some internal bus latencies? Any difference to real life perfomance like 3D ?
Maybe it OCīs better now ;)
Its a Phenom Bios tweak other than TLB fix..its for Optimizing Phenom.
I cant remeber names(items it enables) but has to do with optimization and Power on Phenom..It is not related to the TLB fix...
When i had my TA770 and 9950 @3.45ghz Polygon @ Rebelshaven gave me a Bios with all the (Phenom Options enabled)with a seperate TLB disable tweak . The added Optimizations which are NON TLB Bios tweaks inhanced the performance.
Infact it made the Icon in AOD go from yellow(TLBdisabled) to Red(TLBdisabled +Performance tweaks enabled ,,
It also raised the temp a little and performance was increased on the 9950.
P.S Charged,,
Asus79-T gives me higher idle load temps..They are in fact lower when i disable the CPU tweak but still not what My other Mobo's registerd .Ill dig some more on it and post a Before and After with AOD.
Use Coretemp for VID and Everest.
Use CPU-Z and HWmonitor for vcore and PSU and Mobo volts along with AOD.
CPUTweak On or Off,, Seems when its Off its just as good as when its On for B3's..TLB fix dosnt apply to B3 only optimization tweaks do .Thus CPUtweak is Optimal but with only more Heat involved it seems.,,
The CPU tweak Disabled should ENABLE TLBfix with B2 but Not B3..
B3 will run In a normal powerstate but with performance tweaks disabled when CPU tweak is OFF..It will also not be affected by TLBfix using this Mobo..
Comparison ,,
HWmonitor,, CPU-Z and Coretemp .
Even AODshows a Temp differance Going Red to Green Circle.

Im not one to use AOD ,,but i had to see if i was right about the TLBfix being apart of CPUTweak.. For now it seems TLBfix is 100% disabled with it ON/OFF. For B2's you should see a decrease in Performance with AOD Benchmark tool .. It will be a big reduction like 10% if TLB is enabled vs Disabled.
As you can see (CPUtweak) is performance tweaking the CPU and not using TLBfix(disabled for B3 in OFF or ON mode)..
I would run Everest and other programs but wanted to keep this as short as possiable..
In the End CPUtweak OFF will lower the Temps with out a big impact on performance..Matter of fact some may be able to Overclock Higher with it Disabled..
This is the First time ive ever Turned CPUtweak off and with it on i still achieved 3.5ghz..
So Now i guess ill have to see what i can do with it off:D
Note: OFF vs ON didnt Impact my Voltages r.. if anything im shure it changes how much Power the CPU uses @idle and Under load .
Hope this helps some of ya get higher clocks with out worring about a performance hit from TLBfix,,B3's will be just fine,,
gOtVolTage
Yeah the AOD color thingy changes when the tweak is on or off.
Just tested with 3Dmark06, without the tweak(i pushed the circle in AOD, I think its the same?) it gave 12900 and CPU 4480, with tweak its 13100 and 4580, so little raise yes. And maybe the temps arent really so high even though what the board gauges tells. Leaving it on.
Well your @ 2000HT and the NB is @ 2000mhz
HT can not be higher than NB.
254x8 = 2000ht
1.6 = 8
1.8 = 9
2.0 = 10
Crashing sounds like the CPU or NB needs more Volts to stay stable..
Is it crashing after the CPU is Loaded and HOT?..
I dont know what your temp is ?
Low volts can crash after using prime ,, as heat builds up CPU will need more volts to keep stable..
Also TOO much Volts it will CRASH SOONER.
If your temps are good try raising the NB only..If it crashes right away its a good indication that you may not be running enuff volts or are too hot.
KEEP the HT @ 1.6 and only change NB from 8 to 9. Make shure your HT is @1.6 and not 1.8 when you change NB,, Run Prime ..If your low on Volts or its heat.. Youll crash quik once the Nb is raised.
If you can prime @ 2280nb then You may need to Raise the CPU volts a little to stabilize the System.
1.45-1.5v NB is good for 2400mhzNB even on stock cooler. I suspect your CPU need volts if anything.
Try the NB @ x9 = 2286mhz ,,
254 x 9 = 2286nb
Make shure HT is 1.6 when you change NB to x9
Try that then post results with TEmps..
Also Use the 602bios the 504 crashes alot ,especially with ACC,, trust me.
^^^^^
dammit dude, you just answered everything, give us soms time heheheheh, just kidding, great, you're the best dude!!!
I was on a Roll:toast: while chillin to some tunes...No biggie:dj:
did anyone have a problem putting RAID0 on this board?
Or any other RAID
From what i know the Driver that comes on the CD dosnt work too good for Raid ,,
Download the newest from ASUS..
i dont have raid but thats what ive read.
Using NO CPU TWEAK(OFF) update Amazing and performs nice too
After about two hours of fooling around with Crysis ,, Tropical and playing everything else such as DVD's to mp3's to just Surfing ,Ive noticed no impact on performance by not USING CPU tweak..My Temps are Night and day.Compared to my 3.45ghz post above. Im even using 1.70volts to heat things up,AMAZING i must say just AMAZING.
My Temps are The Lowest ive ever run @ 3.52ghz with No ACC an NO CPU TWEAK.:shock2:
http://i168.photobucket.com/albums/u...c_167volts.jpg
With Tropical running my GTX260 was butter .Almost No load on CPU ..Even though its a GPU test ,,
i xspected my temps to be way higher running this bench in 1280x1024 windowed with HWmonitor running.
http://i168.photobucket.com/albums/u...ra/tropics.jpg
Im really liking this 9950 and Most off all this MOBO..Once you get to know the Bios and such the ASUS 79-T really comes alive;)
Hahaa talk about timing,,Ya keep posting Right when i find out some fun stuff:yepp:
^^^ do you have a 125W or 140W 9950???
:D
XP64bit could be that factor..
I also am using 1.67v CPU and 1.5vnb ATM for those screens..my NB is only @2200mhz ..Although ive run it @ 2675mhz @ 3.5:D
Hmm maybe you can try Manual Oc in Bios instead of AOD?
I can give you plenty of settings to try that will work decent.. i just need to Know What the Current Load and idle is @ your Current CPU/Nb volts..
Your using water and ill keep it conservative for ya
Note: keep Ram @ 1066 and find multi that works for highest CPU clock before raising the NBmulti.. Example try 200x15 ,, 16 or 17 until it works. CPU would be 3.3-3.4ghz Should be 1.55v -1.6volts or less with no ACC and No CPU tweak with stock NB @ 1.35v and VDD @ 2.8v
If you try 1.6 or higher disable CPU Voltage monitoring and check temps and slowly Raise CPU only, Once it dosnt boot it will probally be 3.4 or more.If you need to view volts in Bios you still can by selecting or highlighting disable option it will show current volts in Power.
Your CPU i believe can do 3.46ghz with 203 x 17 @ 1.6v- 1.65v and Stock NB
Send me some Screens.:yepp:
Yup those runs are Spot on.
Latency is nice too.
3.44ghz and 2500+nb is smooth// fast dont ya think;)
Note;
Ive noticed better stability with Medium NB 2400-2500mhz and High Freqency ram Vs Low freqency ram and High NB2600mhz+..
Thus ,,Builds less heat.
Great thank you, also not really stable with ~2.6GHz NB over there I assume. :)
The bandwidth seems to limit the max stable NB speed. When I go higher with the ref HT I have to go down with NB multi to keep the bandwidth lower. The closer I get to the bandwidth limit the higher the voltage requirements for the NB are.
I tested the max ref HT for 4-4-4-12-17 2T in 800 mode. I started to hit a limit at around 225MHz refHT. To reach 227MHz I eighter have to use an lower NB multi (9x) or I must increase the NB voltage to ~1.55V with an 10x multi => 2270MHz. :) (normaly I need ~1.3V for 2.2GHz stable).
it crashes during prime. so itīs 100%loaded and after 20mins i think it also has itīs max temp.
u can see my temp in the coretemp log that i added in my post.
(core)"current temp","low temp","high temp", "load", frequenzy
u can also see the thermal throttle kicking in, this time even at 46°C.
iīm on the 0602 bios.
i really hope they enable adjustments for temp readings in the next bios. i got that on my old dfi board. i canīt work with a board thatīs reading +20°C compared to coretemp and therefore cripples my cpu because it thinks itīs too hot, even when i set the temp reading to "ignore".
I dont use AOD anymore, I learned that already :)
I'm going to go in the BIOS now and raise the multi a bit. Set the voltages accordingly to how you stated and, i'll post back, i'll take some pics if my cell phone can capture something worth taking, as I dont have a cam.
here you go got voltage, cell phone pic, so not great. Check it out, I am posting right now with those settings, ACC +4, I tried disabled and it didn't boot, maybe +2 will do, but I didn't try it.
any suggestions???

^^^and it crashed shortly after :(
oh your right :/ damn this chip.
I changed my ram timing to 6-6-6-24 (31) now sitting with memory at 1,100mhz 1.96 volts gona try 1.94.
My temps go up even with the slightest ram volts lol 0.02 and it go's starts from 34C going up 1C for every 0.04 :/
anyways my cpu score went up, I get gains on Nb mhz too. but can't go past 2400mhz with this chip.
Some more testing with my platform, 3.1GHz and 1.4Vcore yes, 1066MHz 5-5-5-15-2T unganged and NB2400MHz@1.1V, HT2000MHz @defaultV seems to be 24/7 stable for now. ACC at 2%, I dont even know does this ACC work? I get the same results without it .. :/
Still restarts when I try to clock more .. any ideas? 3dmark06cpu 4600 points and wprime 12.4sec, superpi 24.5s
Im probably buying a new PSU next week to see if it helps
Yead i vouce for that,, Slowly tweaking things will get ya the results and Phenom Tweaking is by far not Easy.
I just installed Visat32bit and lost 120mhz on my Max Oc:yepp: The Os plays a big role even when your Bios is set Optimal for the oold Os..So now im trying to get back to 3.52ghz:ROTFvista why me :rofl:
V
Well knowing this makes me feel better. I thought you were already using Vista and I could not figure out why I was having such a hard time. This may explain it. Since I just finished installing water cooling I have tried getting 3.5GHz bench stable and have yet to do it. I got close but I had to use 1.6250 vcore and even though my temps were fine I was still a little weary.
What is the max vcore you have put through your chip? I may end up going to 1.65 tonight, but I do not really want to fry my chip even if the temps are ok.
NB 2.4GHz@1.1V :confused: Typo?
I'd try ACC 0+ and 2+ first see if you can go lower with the voltage. My chip does not work without ACC above ~3.15GHz. I need ~1.45V and ACC 0+ or 2+ for 3.2GHz. Above 3.2GHz 0+ is no longer stable here but 2+ is. But this can vary between chips. I tested low voltage with ACC at stock (2.6GHz). With ACC -2 I found 1.25V but with 0+ it was 1.1825V. So 0+ is best for me from ~2.6GHz-3.1GHz and 2+ for 3.2-3.4GHz, above I used 4+ but that is for benching only.
To find the best ACC value find the lowest stable voltage with ACC off and then test a few ACC values with a lower voltage. Use the one with the lowest requirement. I'd use a lower NB multi and a higher NB voltage to sort out instabilities from that side while you test ACC.
Thanks for advice! And yes it is running right now 2400MHz and 1.1V . default voltage it is? Stable at idle, stable at load, stable in 3D :)
I dont know what makes my comp to restart.. for example, I raise the HTT by 1 or 2MHz and I get about 3120MHz or so, I run torture test or 3D and BAM! It restarts.. it doesnt matter what vcore I use or what ACC setting is used.. And at 3.1GHz its 24/7 stable. Weirdo.. or its just the wall? And I think I get the same restart-effect if I OC the memory even a bit too. :/
And btw I flashed the older 0403 bios in windows .. but the board didnt even boot with these same settings as with the new bios.. black screen and had to reset the cmos by jumper.
I spoke too soon.. I just cant run my NB as high as i did in XP32bit yet:ROTF:
Wierd Vista is just Wierd.

http://i168.photobucket.com/albums/u...ta32bitSp1.jpg
Im still seeing if this is stable ,, At least my clocks are somewhat back up. I honestly didnt think it would run 3.52mhz.
FAIOR,,
Raise your NB volts to 1.45v keep ACC+2 and keep CPUv the same ..Try some benches and let me know ..
Also make shure your HT is @2000mhz(2.0) NOT(2.4)ht..it has to be 2.0 if you raised your NB to 2400.
CPU to NB LINK SPEED(htspeed) should ALWAYS be 2000mhz regardless of how how the NB is clocked.
So for example,,
I FSB/HT @220 x 14.5 =3190mhz CPU
You HT needs to be 2000,, 220x9HT = 1980HT
NB @ 220 x 10 = 2210mhz you will use a 9x for HT although the NB is 10x
NB @ 220 x 11 = 2420mhz you will use a 9x for HT although the NB is 11x
Its critical tha tthe HT remains @ 2000 when raising the NB..If you set the HT to 2.4ht while running 2400nb you will cause a freqency crash as the CPU loads up.. Eventually you will get a instant reboot @ any time..
So when you are running 2400nb make shure the Ht is 2000 NOT 2400 like the NB:up:
My Screens above show exactly what im talking about..
look and you will see my NB is 2200mhz and my HT is 1980mhz.. if i raise the HT to match NB it will crash after a while from freqency loading on the CPU from the HT link not being 2000mhz while comunicating to the NB.
Good luck and keep us posted ..
P.s.
Although the NB is @ 1.1v on your system ,, its why it crashes . The NB needs 1.3v minimum to work properly stock.. Even if you can run lower volts , your hurting the NB's and sytem stability.
You are sure that is NB VID and not the external NB voltage part? I do not get 2.4GHz NB stable here prime95 always fails even with 1.55V but it might take hours. If your NB VID is your CPU VID 1.4V might be abit too low.
Have you posted your setup already here? Do you use 2x4pin 12V rails or one? If one can be you exceed you'r psu's limit.
@gotvoltage: He He it's a mess with 2GB. I tend to run 3DMark06 while running prime95 here every now and then with winxp 32bit 3dmark06 took round 10 minutes to finish. Under Vista 64Bit SP1 it took ~2hrs and the system did barely respond. Still takes longer with 4GB but at least responds while running prime95.
Hmm, now you say it, the NB vid is also default 1.3V, didnt know it was the real NB-voltage setting. "NB-voltage" is default too which is the 1.1V.
I am currently pretty sure too that my PSU is limiting, I have only 1x4pin attached, I did built the 8-pin my self, but havent tried it yet..The restart-effect clearly could be something to do with power. 12V line is 12.03V so no problem there thought.. :S
Setup is somewhere yes.. not far away.
Saw it's only 16A on that rail with an 18A single rail max voltage I could apply was round 1.475V(~3.25GHz).
Chip worked stable here up to 85°C max, above the system froze and I could fix that with better cooling.
With 1.3V my NB runs 2.2GHz stable (12hrs prime95 tested).
During my testings I also found that increasing the ref HT sometimes results in up to +0.1V higher voltage requirements for the cpu.
You need to set NB on CPU to 1.3volts or Higher for proper function of CPU. @ 1.15v even @ stock speed will eventualy cause any Phenom to crash regardless of CPUclocks.
1.3v for NB is how your ram is kept stable too..the NB is your IMC. So if you have lower than stock volts you can cause your ram to Reboot your Pc over time. even if you are using 1.8v Jdec seting for basic 800mhz ram.
I'am sorry guys but i can not help my self HaHaHaHeHeHeHaHa !!!!!! :rofl: vista-32 bit is hard to over clock. Any time you guys are ready to move up to the real deal vista-64 bit and see what happens to your overclock . PS. All in fun i just find it funny.
Hahha i knw what you mean.. My other Phenon runs 64bitVista and clocks like crap..
I just decided to see if Vista32bit could clock as High As Xp32bitSp3..
I finally was able to get 3.52ghz with Both Oses .. Vista is more demanding and to achieve the same 3.52ghz as XP32 i had to lower the NB to use the Same CPUclocks and Ram speed and Divider.
I dont even care for DX10 seing that DX9 is fine enuff for me anyway.. Only reason i stuck with XP32 for so long ..It does what i need.
As for cooling ,, Makes Overclocking night and day to have good water setup or High end Air.
(Stock Heatsink i maxed @ 3.3ghz 2400nb..)
Was cooking Hot when i tried that with 140watt 9950:D
On DX10 i my self like playing crysis using DX10 and 64 bit i think it make the best looking crysis . Grats on been able to hit the number you wanted on your overclock as well .
Weird, mine clocks the same in Win Xp 32 or XP 64 or Vista 32.. I don't have Vista 64 to test yet
Anytime;)
Update ASUS 79-T using ACC+4 and lowest volts i can use in Bios..
Hope This is Good for Vista32bit @3.52ghz:D

Hi guys!
I have one question about this MoBo. I have 3 disks in raid 5 and 1 single disk (without raid) and all works. Few days ago I bought SATA dvd driver, my old PATA driver died. RAID controller see that SATA dvd driver is connected to SATA port 5 but my system (Windows XP SP3) don’t see this driver. What I have to do to make this sata dvd visible to system? Or maybe it is impossible to connect SATA optical driver when SATA controller is in RAID mode?
Thanks in advice for your help.
Hmm, probably a wrong thread to ask, but what scores you guys get from cinebench r10 and winrar 3.71 .. clocks at 3.0-3.3GHz ? Ive got 10k cinebench and 2300 winrar, just wondering are these correct..
Well I actually got vista to load last night with 3.52 last night "once". It took 1.63 volts to do it. However it did not last long. I opened up AOD to check temps and everything seemed ok, but then it suddenly blue screened on me. I tried to get back into windows, but that was a no go. So I upped it to 1.65 vcore and it still would not load. I tried a few different ACC settings but nothing seemed to make a difference. I did not have too much time so I will have to go back later and play with ACC a little more and see if I can get it, I am starting to think this chip just will not do 3.5 on all cores for benches, but at least I did not kill it :D
Hmm what the heck, now this thing DOES boot when ACC set to 6%, I havent really changed nothing, only put some more clock to NB, memory, HTT and pci-e. :D
Btw, what does the CPU VDDA voltage do? Where should it be when overclocking?
And this still reboots if too much clock, tried 1.5Vcore, open window(freezing -8C outside..) and I put the 8-pin homemade adapter to the motherboard.. no effect :/
edit, some more to ask for, PCI-E watt limit.. at default its 25W ? .. what the hell is this, I tried 100W and all tests ran fine, but games usually goes to blackscreen and the graphics card starts to malfunction weirdly .. Allthought the comp doesnt crash, just the screen goes black(powersaving..)
I read manual and found this:
But as I said earlier I have 3 hdd in raid 5 and to make they work "Onchip SATA Type" is set to RAID and I can't change this to AHCI or IDE.Quote:
When this item (Onchip SATA Type) is set to [AHCI], only SATA connectors 1-4 can be detected. Ensure that you've installed the AHCI driver, so that you could use SATA connectors 1-6 in AHCI mode under OS.
Any other idea?
AHCI is used by default when you set the SATA to RAID...!!!
You'll no doubt have noticed that the driver you install when setting up RAID, is an AHCI driver..!!!!
Yupi! I changed port where DVD burner was connected and now it works.
Probably optical driver should be connected only to 1-4 ports, no to 5 or 6. The last two ports should be used only with hdds.
Thanks for your help!
Thats the Wrong PCI-E watt limit your adjusting.. The correct one will be preset @75watt...I believe its Lane #2 and #10..Just go throught each and only set the ones that ALLOW 16x. There will only be two lanes that run 16x.
NOTE:
In the same Menu pressF4 and 10 new PCI-E lanes will pop up on screen..
Two of those lanes Are X16lanes ...I set those to 200watts and AUTONONIMOUS.. I leave all other Lanes AUTO.
Also VDD is the BASE Volts for the Mobo.. The Higher You raise this the More Overall Volts you can achieve with VCORE and ACC.
I allways run @2.8v VDD.. 2.5v is default when on Auto.. Setting to 2.8v garentees that it wont Drop below 2.8v when overclocking..
.Also you Should Disable ACC and set 2.8v VDD for now and Manually Raise the Vcore For CPU/Nb slowly to see what makes its stable..This way you Know ACC isnt causing the Reboot...
Many things can Happen IF,,
If volts tooHIGH/LOW can reboot.
If CPU too HOT can reboot>
If the HT is too high it can reboot .
IF the NB is too High it can reboot.
If Ram timing is wrong can reboot.
If power supply is weak Can reboot..
thats just a few things to mention.
For a stock Phenom i would not use less than 500wattpsu that has a 8pin on it with at least 36amps on the Rail.
Try setting just the CPU Multi with Stock NB and NB 1.35volts ..On stock cooler you should be able to do 3.1/3.2ghz but will need to play with CPUvolts and Id use the 800ram or 1066ram divider if you have 1066..
P.S. BENBROWN
I use 1.68v CPU and 1.6v for NB while NB is @2000mhz for 3.52v.. These things like the Volts to somewhat be close together with the CPU bieng the same or Higher than NBvolts. For 3.5ghz with NB@2600+ i use NB@1.65v +2ACC . Now the sad part ,,just to run 20mhz higher:ROTF: i have to lower the NB to 2000mhz because this is my CPU's cieling no dout.
Ha haa how much do 45nm weigh?,, Santa's Sliegh with $h!tloads of them gonna be Heavy Eh:rofl::up:
Very nice tips again! :) Thanks. Sorry for all these questions, have to learn .. things.. to clock.. ;)
But yes, the F4 would be the answer, I was trying to find those lanes which are in the manual too, but couldnt.. F4 solves this I think. So 200W for them and ACC off .. hmm Ill try. I have Arctic Cooling A64 Freezer pro doing the cooling now. Btw, new Enermax 525W Modu82+(3x25A rails) PSU coming this week too, maybe helps, maybe not, ready for CF then if not.
This Antec NeoHE380W has got some great performance in the past in some tests so I dont think its the fault now altought.. But never know!
It has 3x15A 12V rails .. not sooo bad, but if the phenom just draws some power what you can do. .. :D
But thanks very much.
Your Antec very well can be the problem..
380watts (9550 needs at least 400watts to work decent Overclocked minimum with Mobo and attached devices including a hungry Vidcard that uses PCI-E6pin..) Your Vidcard alone can eat 180watts ,,dosnt leave much for Devices and Mobo now does it:D
Okay, done AGAIN (:rofl:) some testing aaand:
ACC doesnt make a difference to the rebooting issue, it does it always when I go to 3310MHz and make it to run superpi, approx 10secs and reboot. Always, i tried 1.6 vcore, all other MHz to default except cpu, no difference at all.
Also it seems that core 0 and core 3 are the weakest one, core 0 starts to restart after 3200MHz. My best superpi run was 22.8sec at 3300MHz core 1.
Tried about every voltage setting and some other tweaks, Id say its the PSU now, or WALL(which I dont believe). It was little weird at first because I got the cpu to run superpi for about 10-20 times stable without acc, then I enabled it and it restarted again, then I put it off again and it still restarted, so dont think its ACC issue after all.
Also I noticed that running ACC on gets your memory benchmark results down a much (eg. read 8500 -> 8200, copy 10000 -> 9500, latency 50ns -> 53ns, also everests CPU Zlib 82600 -> 78000KB/s .. weirdo isnt it?) This affects to real life applications too by a bit. AOD benchmark gives better results too without ACC, and some variations are gone (examp:first run 9300, second run 8900, third 9200 etc, now its stable 9300 every run)
Better wait for the psu and try again, althought this isnt slow at 3.1GHz :up:
BTw, this Antec could run FX-60 overclocked a much, 2x 1900XTX in crossfire overclocked, and still got juice, was getting about 500W off the wall tested by The Stilt if you know him. :) Dont know can that comp be compared to Phenom and one HD4850..
Hmmm my 6000+ @3.5ghz runs fine with a 500watt Antec and TA770. But once i installed the Phenom9950 (140watt) @3.2ghz and 8800GTS(G92)512mb..It would shut the system down..
I replaced it with a 650watt ThermatLake Modular which enable dme to Get 3.5ghz on SB600 and now this same PSU which runs My SIG.
Hey Man, even though you scare me sometimes with your voltage recommendations :p:... I have been paying attention to your suggestions seeing as how you get such killer clocks!
I'm on air, but temps never really seem to be too much of a problem, I did hit 60c on a 10 pass Linpack run, but I don't think that's extreme considering the load I was putting on it...
You may have seen this SS before, but this is my best stable clock using XP64. Even though it did pass 1hr Prime95 and a 10 pass Linpack run I still had to up the V's a little (Vcore 1.425, NBcore 1.325), due to a VERY RARE crash (once to be exact :D)...
http://i30.photobucket.com/albums/c3..._AODStable.png
Anyway, I tried for more tonight... I upped the Vcore to 1.475v and the NBcore to 1.375v (I also set VDDC to 2.8v) in Bios. My machine would try to post (not a hard crash) but kept giving me the F1 reset Bios error. :shrug:
I have a decent PSU (see sig), but I'm really starting to wonder if it might not be enough to push those volts... Either that, or my chip is just a wimp. :rolleyes:
What do ya thing? ;)
TIA..... Dave
What was your HT speed? As gotVoltage mentioned a few times for higher NB speeds high HT speeds are a must. I can select above 2GHz here on the AsRock in the bios but at max 2GHz(10xmultis) are used.
BTW: LaingUltra leaked, shortened , burned a hole in my table and stopped working. :shakes: Waiting for an D5 vario now.
Dang ,,bummer
ALSO you can mod the D5 real easy for better flow
The D5's and or 655's are great little pumps...What works for great flow is drill the Inlet to !/2" ,, this will let the pump draw more volume from Resivior while keeping the same Head Preshure but with hihger flow. Its an easy 5min mod with a 1/2"drill bit.
On to the good stuff,,
As for Phenom Volts ,, i cant believe How much these things can take even with a stock heatsink.. The trick is to allow good volts but keep the temps in check.. Heat is the Number one ccause of Phenom failure along with the old IMC the B2's used. The B3's Handle Ram volts plus high NBvolts way better than the Old B2's.
For using 3.2-3.3ghz with 2400nb ..Even on Air (nonstock cooler) ive found that 1.48v -1.5volts works graet on the CPU/And NB with or with out ACC.
When you raise the Volts up you can use ACC in Munus mode -2 -4 aand so on to lower the overall volts Idle and Load although using higher manual settings for NB and Vcore..
It takes a lot of tweaking and all my Overclocks are done with high volts up to 3.3/3.4ghz and High NB just to see what it can do and watching my Temps . if its under the Max temp limit i lower the Volts a hair NB then go for Higher Clock values.. Ilways run the HT @ 2000 or Higher depending on My NB speed.
At high CPU clocks the NB @2000 -2200mhz can perform. Highe rCPu clocks along with low NBmhz do better than Low CPUclocks with HIGH NBmhz. Least thats what ive been seeing.
In the end its all realted to Heat ..Start stock with like 1.5volts for both CPU and NB and slowly raise the CPU to its highest level using just the Cpu Divider(multiX) with Stock NB..
yOu should be able to reach 3.2ghz with a decent air cooler and even the stock one on B3 9850/9950. Default VID is 1.55 for both CPU and NB .
Even My TA770 was default with 1.55volts for both thats how i discovered this way of overclocking. You can use ACC to Lower Volts when using High manual CPU and NBvolts aswell.
Theres just so much more of a challenge with Phenom overclocking when i compare to friends Core2Q's..
In the End they all ask why my Pc seems faster than thiers when they are @3.6 and im @3.5ghz..It seems kinda amazing to me how smooth the AMD platform really is @ any speed conpared to all my Friends Intels.
Help me understand again the reason why you need or should keep your HT @2000?
I am at and cannot remember what auto cranks it up to, but I am stable at 3.3 and can get 3.5 with this approach.
Thanks for the insight in advance.
HT On auto can be unstable in most cases and or it Can atomatically lower the HT for you if it works correct
Ive seen the Later(unstability when using AUTO HT on Most Mobo's when you pass a Certain point of OC.
Even @ stock i set the ht To 2000 even if my NB is @2600.
Although i have tested it to 2700mhz @ 3.5ghz:D
Each chip runs different and HT will vary but i use the same Method to set and or use the HT when overclocking on every Mobo ive tested.
Example ,,
why i set HT to 2000 regarless of NB speed ,,
Say if you set NB @2400 manually ,,the HT setting will show 2.4 = 2400 mhz automatically.Auto usually dosnt set it to 2000 all the time for HT at least.
@ HTT/fsb 200x13 9950stock ,,
the HT is 2.0 and NB is 2000mhz .Now if i raise the NB to 2400 the HT will automatically run 2400..If the Mobo or chip dosnt like it you will crash .
So @ 200x13 i will set NB @2400 and set the HT @2.0 = 2000mhz
The HT link that shows up when you change NB speed is the HT from CPU to NB . CPU to NB HT should be 2000mhz for stability.
Now if yo raise the FSB/HTT to 220x13 = 2800cpu ,,the HT usually will raise to 2200 if on auto or stock along with the NB.. In most cases the NB will be stable and HT at low CPU clocks(below 3.0ghz)..
Once the CPU goes above 3.0-3.2 this can or may become unstable and thus why i recomend to set the HT lower when you raise the FSB/htt ,Unless you have test the HT to go up to 2700mhz using low xCPU divider and raising FSB/HTT . The first thing i do is see what the Mobo can do on the FSB/HTT and how high HT can go before ever Raising my CPU overclock or NB @ stock volts.
Stock HT = 2000
210 HT = 2100
220 HT = 2200
230 HT = 2300
240 HT = 2400
and so on,,
Max ive ran HT is 270+ = 2700mhz HT.. 292 x 13.5 @ 2500ht. Its not easy by all means.
The NB acts the same exact way on My CPU..
If you are not giving the NB enuff volts you wont be able to run High NB and the system will not let you run High HT if NB is not stable.
Both go hand in hand , except that the NB can be higher than HT ..Thus i wont use auto HT becuse mostlikely it will not work as intended and crach the Pc.
So in this case i always set the HT to run @2000mhz regardless of my FSB/HTT and NB speed. The Higher the FSB/HTT the lower you must set the HT and NB depending on how fast your NB can run.
Example,,
210 x13 = 2700cpu and 2100HT/NB
usually HT can run 100mhz above stock when raising FSB/HTT
220 x13 = 2800cpu and 2200HT/NB
Sometimes you need to lower this HT back to 2000 which means using 1.8ht instead of 2.0HT.
So in Bios your setting will be
NB 2000 @220 x13 = 2200nb
HT 2000 @220 x13 = 2.0 = 2200HT( USE 1.8 instead of 2.0 to get 2000ht)
@240 x13 you will use 1.6 to get HT2000
You can run the NB well above the HT provided you give the NB the volts to do that.
Although ive seen many systems incuding mine run HT 2600 @ 3.5ghz it all depends on CPU and how high its clocked.
You need to play with HT.
Some systems like High HT and some dont. I usually see how much HT and NB i can run @ below 3.0ghz..I max them both out.. I then see if i can raise the CPU xmulti more If im using FSB/HTT(stock or even raised above stock). if it crashe with Higher CPUxMulti Lower the NB and or HT till it works..
Then i repeat the steps and eventually mu CPU is running higher clocks
Sorry for Long post,,
Not easy subject to absorb,,
gOtVolTage:D
Hmm, have you reached an point where too low HT speed was the cause of system instability?
The Asus board seems to allow an 10x max HT multi like the asrock or can you use higher multis if you use higher NB multis?
Could you run mem at 800 mode with an 270MHz ref HT and 10x NB multi or had you used 667 mode?
Thanks for the modding tipps saw you did a similar mod to the d-tec. I hope the D5 is more shortage prove and I like the fact that it's variable in speed. Was just a small leakage on the reservoir on top of the ultra, but the pumps bottom is not waterprove so electronic blew up.
^^^^JustaPost^^^^
Hmmm ill have to remember (looking for Screens).. I think i have one where i used like the stock 10xHT/NB multi to get 2600+HT with 800ram or 1066 @13xmulti i think.
Also if i run less than 1800HT System dosnt like it at all . My NB wont even run Below 1800mhz.. Since NB is designed for 1800minimun on Phenom.
I pretty much can use 400/533/667/800 for High HT..Depend which ram im using . Also i up the HT volts to 1.3v-1.32v for Super duper High HT:D
Ill see what i can find .. Havnt tried High HT since i Ran 292 with this Bios..I kinda just did some Quik tests with out saving Bunch of screenies..
Above 3.5ghz my system like the HT to be low due to My CPU and High Ram Freqency. I do Know Usually you can sqeeze more HT while running below 1100mhz ram and 3.5ghz .
Note:
while using 260FSB/HTT 260 x 13.5 = 2600mhz HT on this Mobo . I also used 800 Ram divider with 1066 ram. HT will be set to 10xDefault My NB can also do this @default 10x:D
The Higher the HTT is raised Past 260 on this Mobo with 602Bios the harder it is to keep High HT.@ 270-280 i would have to Lower HT to around 2400 or less. @ 292 i have to use 2000HT to keep Mobo Stable with 1.32v on the HT. Waiting for New Bios to get that Majic 300!HTT
Ive found that after 292 All my Dividers and CPUxmutis result in raising the CORE to above 3.6ghz .. Even if i use a low CPUxmulti it will say its @ 3600 if i try to set 293x12 = 3516,, the Mobo will report as 3600mhz. Same goes for if i Try 11x 10x 9x 8x it will not boot and say that My CPU is 3600mhz or Higher/ ive even seen 4800mhz in Bios!
This is Clearly a ASUS BIOS Problem with the Dividers for Ram and or CPU when going above 293htt.

yep, I Phenom overclocking is def. not easy I agree.

if I can't RMA my board or exchange it locally, I think im going to try core i7!!
not what I want to do with Phenom II just around the corner but its been itching for a while now.
BTW, when i had vista i saw some decrease in performance too!, so you're not alone, dont feel bad :rofl:
here is my unganged scores..CB10 and RAR, They do look a lot better..

YES thats better,Thats what we like....
Thanks, Next up higher clocks (when I get some time):p:. I don't know about anyone else...it is either this 125 9950 is a nice chip or this board just enhances performance. I have a lot higher scores on this chip and board then I do on my 140w 9950 and the MA790GP-DS4H setup
Ya..I have one 9950 on Air..but it is XP Media Center...the other has XP 32 XP 64 and Vista 32. Looks like Phenom II will love my water setup I get 26*C on idle with 3.3ghz 1.4v.
I really do like the Phenom's these 9950's have been super fun, and on this Asus board..even more fun. Very solid setup.:)
up to 3.4ghz in Win XP 64bit...I lowered NB to 1800 and HT of course followed suite, to see if it would effect CB scores.. I actually ran 1min and 6sec which was the same as my 3.3ghz and 2000HT and 2400NB...
http://3800z24.info/Phenom/9950/winx...ench64_3.4.JPG
Now..what I find odd...I can boot into Win XP 64bit @ 3.4ghz...the exact same setting on Win XP 32bit and blue screen. 3.3ghz is 100% stable..but 3.4 no go..
Any know of a means to get more voltage beyond the bios max? vcore is capped at 1.7 and vdimm at 2.5, kind of a low cap to put on vdimm... maybe a modded bios in the wild?
Yep, got my new PSU (Enermax Modu82+ 525W with 3x25A 12V rails) and Thermalright Ultra Extreme 120 cooler, btw dont :banana::banana::banana::banana:ing buy this cooler for this motherboard.. it gets wrong way(the fan blows against the VGA-card) and didnt almost not fit to the board at all, also 1 memorystick place cannot be used at all with this. And was very very hard to attach the screws(althought didnt have to remove the board from the case).. and the case didnt almost not fit to close with this :D 1mm space between them.
But, some good things too.. idle now 39C without CPU Tweak option and with it 45C, old temps were 45 and 51C, also load dropped from 62C to 52C.
And the problem with the overclock, black screen etc .. it is still there with new PSU :( Im gonna try older bios if it fixes it.
Heres a pic from the comp. .. perhaps I should by a new Case :D
well i was able to boot into windows 32bit @ 3.4ghz...I am going to try some benching and see ow it does..I am sitting at 31*C at 1.55v 3.4ghz right now. I thought my wPrime score would have been better....

Can anyone help me with an overclock?
I just got the m3a79-t with a phenom 9950 BE, and the highest I can get it it stable is at 3037 mhz, 225 fsb, with 2250 NB and HT. Vcore and core-NB are at 1.35v, VDDA at 2.8, and HT, core/pcie, and SB all at 1.28v. ACC is at +2% on all cores.
If I do just the multi i can get 15x200 at 1.35v Vcore, ACC at +2 and drop all the other voltages to their minimums, stable.
I've been trying for 3200mhz, though, and nothing I do can seem to get the chip stable at that frequency. I've tried just 16x200, and run the vcore and core-nb up to 1.525v, with vdda at 2.8 and other volts all at 1.28. Even at ACC +4 I cannot run any stress test for more than a couple seconds at these high volts. Temps are good, at 3000mhz the hottest it gets is 51C running OCCT, and at 1.525 it runs about 60C before crashing.
Is there something I'm doing wrong? I originally had 8GB ram installed so I took out 2x2gb to see if that was the problem, but it runs the same. I also had a RAID setup initially, so I turned that off and am running in IDE mode, but that didn't change anything either.
Any help would be appreciated.
what are you cooling with and what is your PSU? also ram type and config...
Cooling is Thermaltake Bigwater 760is. Yes, after getting it I've seen the numerous complaints people have on forums about Thermaltake water cooling but I wanted to make the jump to water cooling and so far it's run much cooler than any air setup I've ever had so I'm currently happy with it and it's too late to take it back now so I'll just keep it until it dies.
The Ram i currently have installed is Mushkin 4GB XP, which I've had at 5-5-5-15 2T timings while trying to get overclocked. I've run it up to 5-4-4-12 1T at 900 mhz, and 5-5-5-15 2T @ 1066 in memtest with no errors, so I don't think that should be the problem.

Originally I also had G.Skill PC8000 installed alongside it, and took that out to see if that was causing problems.

Post a AOD or CPU-Z sreen of Ram and CPu settings along with Idle Temp and LOAD temp..
If your Temps are really High that might explain why your Oc is capped @3.2ghz.. Im shure between all of use here we can help to get you Higher in CPUclocks:up:
NOTE: MAX VOLTS .
MOBO can vary 1.73v+depending on ACC if you choose to use it. Dont try Max Volts unless your 100% shure you have enuff cooling.
Ive benn running CPU @1.65v - 1.6875 with ACC+4 @3.52ghz and it gets me 1.73v Idle and 1.74v load.
My NB is @ 1.65v for up to 2600nb@3.5ghz this will give 1.55vid.. if you go above 1.65v the mobo will start setting Lower VIDs and Use More Vcore.
ASUS 79-T Max Volts for CPU and NB will cap @ 1.7v if you use VDD @ 2.8v it will allow 1.74-1.75 under load and 1.72v -1.73v idle. Also ACC + settings can raise this a little more under load. I dont know of a Bios Mod to get higher Volts ATm.
Oh gotta cut the lawn now,,
Hehee didnt know its suppose to Rain tonight. It will free up weekend to play with Bios More(voltwise :D) maybe i might stumble accros something:shrug:

LOAD
https://webspace.utexas.edu/ecc55/Music/300load.jpg
have you tried leaving Ht refernce at 200 and using multi only and ACC on auto?...Also try the ram at the stock settings and like I saidm try multi only leave NB /HT stock as well. All 3 of my Phenom's (9850, 9950 140w, and 9950 125w) would do 3.2ghz @ 1.4-1.45v. on the asus board or the gigabyte (see sig). your temps might be an issue on the load side...
Okay, I set ram below stock (5-5-5-15 @ 800) and set the FSB to 200, with NB/HT at 2000 and ACC on auto.
I tried the multi at 16x200, and all volts at stock except for vcore, which i pushed up to 1.5v with no luck.
I then tried to up the other volts (VDDA @ 2.8, HT/SB/core-pci @ 1.28) and pushed both vcore and core-nb up to 1.5 and still no luck. I just cannot get this thing to run at 3200mhz stable.
EDIT: Here's the error I keep getting:
