Are you getting errors in memtest, Prime95, bsod's? How are your temps? What are your components (cpu, ram, motherboard, cooler, ect.)

Prime95, BSOD's when I was clocking higher.

Temps don't go over 44...currently maxing at 42 in prime95

Phenom 720, 790XT-UD4P

Ram is what I mentioned previously. the OCZ 1600 LV AMD Platinum. 2x2gb

TRUE with a L1A, arctic silver 5

I am at 1.4 NB/SB +.275 on the nb/vid, 1.475V CPU and my memory is running at 1.75V

I can get my NB Freq to 2400 like this running at 3500 on the CPU.

1.4v on nb and sb sound too high. Try 1.3v nb 1.25 sb
Ram is rated at 1.65v, why are you all the way at 1.75v?

I will back down the voltages once I have it all stable.

The memory would not run at 1.65 at 1600...I am now at 1467 on it, 2420 on the NB, and 2200 HT. CPU is at 3520.

FWIW man, PHII's are very sensitive to voltage unless you can keep temps under control. From my experience cranking voltages to find your stable clocks and then lowering them afterwards is NOT the best technique....

It's tedious, but you'll get better results by testing each component seperatly and only raising the voltage until you get diminishing results, at that point move on to the next component (ie: Mem/CPU/IMC)...

The bios (on the 790XT-DDR3 version at least) is quirky with the CPU-NBvid setting and it's impossible to tell what it's actually set at.
+.275 seems a little high to me and may be part of your problem.

Unlocking any chip for extra cores also screws temp readings on all mobos as far as I know, so unless your measuring with external hardware (DMM/TempProbe) take the software readings with a grain of salt.

On my board (MA790XT-UD4P), HWMonitor seems to give a fairly accurate reading of the CPUcore with the "TMPIN1" temp. Every Phenom I've ever had gets squirly when the core goes >53c, watch this temp and if you notice the same tendancies either adjust your cooling or voltages to keep it in check..

Hope this helps, OC the way you see fit, but cranking voltages isn't always the best way to work with Phenoms....

Keep the SB @ stock volts and NBchipset @ 1.32v max or just leave that on Auto.

As for NBvid you should only need +.100 or +.200 max for the NB even @ 2600mhz NB with the CPU Cranked @ 3700mhz+..

I agree 100%,, When im going for max Clocks i do the Ram first then set it as low as it will go,, then i Crank the CPU not NB .

The last thing i do is Play with NB with medium Oc on the Ram... It will take a while to get Max CPU and medium NB with good to High freqency stable ram.

Its a true Balancing act and Voltage should always be added as a last resort when you reach a given MHZ and can not go further..

The Temperature of all things combined will deter what the CPU is gonna give you in the first place.

Tweak slow for best results

Note; UD4P /550x2 @X4cores with good water im @ 4000ghz with 1.52volts and 2600nb @ 1.35v (ram = 1100mhz )for 24/7 gaming.
Im hoping DDr3 should get even better NB with higher Freqency ram once i make a swap to DDR3 ..

I rose my volts over testing at lower.

My CPU is not unlocked. I am running 3 cores only

I had been at 3.6Ghz stable @ 1.45V but raising any other setting caused hangs when starting CPU-z or errors in Prime95 (occasionally a BSOD at high settings).

Can't seem to stabilze at 3.6GHz at 1.45V anymore. If I raise my NB to anything over 2000 my keyboard is flaky in the BIOS (either doesn't work or requires a mouse movement to register a keystroke).

Last night I just started over, baselined everything and am working on CPU.

I am hoping it's not my PSU. OCZ Modstream 520, it ran my 8800GTX and Opteron 165 @ 2.7 fine at 1.5V and the 8800GTX at 600/1470/2030

The system differences now are going from the Opt to the Phenom 720, 2x1GB of G.SKill to the OCZ 2x2GB AMD Edition, swapping out my Pioneer DVD-305S and DVR-108 DVDs for 2 Pioneer DVD-216's and no longer able to use my Santa Cruz sound card.

i have been overclocking for 10 years, and i have what should be a very simple problem that i just can't fix and i need some help from you guys. for whatever stupid reason i can't increase the CPU voltage in the bios at all

i recently got this hardware:
Gigabyte MA790XT-UD4P (this is the DDR 3 board)
Crucial Ballistix DDR3 1333, rated for 6,6,6,20
Phenom II X3 720 BE

other hardware:
4870
Seasonic 600watt PSU

either i am missing something ridiculously obvious, or i have gotten 2 bad motherboards (i have tried this with 2 of them).
i have successfully unlocked the 4th core on my 720, i am on the F4G bios, but i have the same problem with the F4 bios.

the only settings i have changed in the bios are unlocking the 4th core:



and then when i attempt to increase the CPU voltage even the smallest amount, it locks up right when windows should start loading. it is driving me nuts, i have been trying to fix this for 3 weeks and just can't get past it. i can overclock just fine in windows, but i want to set it up for 24/7 in my bios. thats how i have run all my machines for many years.



at this setting it crashes. so what gives, all other setting in the bios are default, why can't i change my voltage????? please help!!!

[mondena]

just for reference, when overclocking in windows if i set CPU voltage with easy tune to 1.525, my system is IBT stable @ 3816.

i wouldn't use that high of voltage for 24/7, but i would like to find something in the 3600-3700mhz range for permanent use.

i'm using an Xigmatek S1283 for cooling.

Um it shows the stock vcore for your 720 @ 1.25v. Isn't that really low? Anways you should at least try to raise it to 1.47 and see how that does.

i have tried more (i would like to use around 1.45-1.5 for 24/7), i have tried almost every setting, none of the extra voltage adjustments seem to work, it always locks just before windows loads.

[gOtVoltage]

Ive found when using F5 bios UD4P,,

Hybrid mode is the best option to run when not using a X2 X3 chip.

The normal firmware acted funny when i used my Chips in X2 mode\X3mode and even my 9950 was buggy when trying to Oc like mad.

Hybrid Mode worked best for all my CPU's regardless of the Cores Type.

If you want o keep X3 or X2 the Stock core dont use ACC when using Hybrid.

ATM Hybrid just works

[mondena]

thanks for the info gotvoltage, although i'm not sure i fully understand you.

My X3's 4th core does work successfully, therefore what i want is all 4 cores running at 3.5+, and that seems very reasonable to me (i know my chip can run at that from my windows based overclocking, but i want to set it in my bios so i can just leave it there 24/7 regardless of what software i change).

i have it set to Hybrid mode, right now i have the ACC set to Auto, if i change it to "per core," i still can't adjust the CPU voltage.

[MrRuckus]

I thought I would just throw some pics of a TRUE 120 on this mobo here incase people are wondering. As seen by an earlier poster, the ram slots being so close to the socket seem to block dimms 1&2 if you have a large cooler. Being that the mounting on a AM2/AM3 = rectangular, at least with the TRUE 120 it can only be mounted one way which blocks the dimm slots. Not a big deal imo, but something to note. It fits but its close even with only 2 slots occupied.

My OCZ3P1600LVAM4GK's fit fine in slots 1and2 on my 790xt-ud4p with a TRUE.

He has tall ram heat sinks on those reapers.

[alk3myst]

yeah just mentioning normal ram is no problem.

Have you Tried raising the NBvid to +100 or more then Raising the Slowly start clocking the CPU.. Once it wont boot Add +vcore untill its stable.

Your Voltage settings should work regardless to raise Vcore. Use the 14x multing in BIOS and try raising the HTT.. Ive seen Some Mobos Lock the Stock multi on 720 when unlocking.

Even my 720 @ 3500mhz X4 cores required 1.56volts and 1.4v on NB with stock NB on UD4P (Watercooled)..The DDR3 Mobo is simalar.

My Max 100%Stable was only X4 @3650mhz with Stock NBmhz on UD4P. The 720 needed Highvolts to be stable @ 3650mhz X4 and 3950+x3 mode while using water. My Air runs where almost 200mhz lower in X4 and X3mode with almost the same Volts.


I would reset everything to stock then ADD .+.100 = Vcore 1.35v ..Go into windows at stock and use CPU-Z to verify the Volts went up. Or check Voltage Monitor in BIOS make shure it reads the Vcore higher.

If your Vcore is raising and windows is BSOding you may have some hardware Driver problem(graphics driver) maybe that crashes regardless in X4mode..Thats a whole other topic.

Keep HTstock and NBmhz stock so you know that isnt affecting the Volts of CPU in Bios.

Have you tried the two other Ram slots then reboot.Have you tried other ram? Youd be suprized what a Bios can do when it dosnt like RAM.

Ive seen some wierd stuff ,I usually will tear down a build and start over when i see No volt controll change in Bios,,it can be Bios,, Ram,, HT,, CPU and even a bad Flash and or Ram or even a piece of hardware that dosnt get along when you try to change the volts..

[MrRuckus]

My OCZ3P1600LVAM4GK's fit fine in slots 1and2 on my 790xt-ud4p with a TRUE.

Ahh good to know. I didn't try any other sticks. heh.

[Maranello]

Thanks for the help everyone... this thread was a god send

I was running Prime95 at 3500MHz and rebooting after 30 min (BCCode 124)... just ran an hour and everything was fine. I wasn't using enough NB VID before.

It's a 720BE on the UD4P with 2x2GB Mushkin 996599 1066. All cores do unlock but I haven't really pushed them as I wasn't able to get anything over 3400 stable before with 3 cores.

[jlacy76]

This looks like a hard board to unlock and overclock the 720. It it just the northbridge voltage you have to watch?

[Snowman89]

A quick question. How much vcore and vdimm can the ud4p board provide through bios?

[Daveburt714]

Snowman89: Just rebooted to check for ya...
MA790XT-UD4P (ddr3 board)

Bios Max voltages are:
Vcore = 1.95 volts
Vdimm = 2.35 volts

Both are more than you should ever need, even with extreme cooling!

Big thanks to you!

Yeah Maxed my 940 with 1.6-1.65v on di so 1.95 is waaay to much

Use sparingly

It actually volts better than my M3A79-T and that mobo was a tank when it come to volts.

Gigabyte is very fun to tweak , PHII's are just very time consuming to find what freqency works best ,,other than Volts on these Mobos lots of times youll find Lower volts clocks alot better..
