X3 720 Voltage issue

[El Greco]

My X3 720 needs 1.44 voltage in order to be stable @ 17 * 200 =3400 with stock amd cooler.. do you think that is too much??.. Temp @ full load 55 -57C
I am thinking changing the stock cooler so i can go further ,thinking a small good cooler ( i have a midi case )

1)Xigmatek HDT-S983 Nepartak
2)Xigmatek HDT-S963
3)Scythe Shuriken Rev.B
4)Scythe Mini Ninja ( maybe this one)

They are cheap and smalll but are they any good?

That's not to bad considering the 1.55V is the max you'd want to have your Phenom running at.

[Oldguy932]

Did you really set 1.325v and get 1.44v? Not sure on what cooler though, mini ninja has the 9850 in my girlfriends computer get up into the 50's range with it at 2.7ghz on stock volts so no idea if that would be much better for you.

[El Greco]

Did you really set 1.325v and get 1.44v?.

No ,the default voltage is 1.31..so i set Vcore +125mv on my dfi's bios and that gets me 1.31+0.125= 1.435 ~ 1.44Voltage stable @ 3400mhz..
..i tried Vcore +100mv .. 1.31+0.100= 1.41 i it was not stable....

Was it at least quite ??

my 720 needs 1.44v to reach 3.52 (16 x 220). i have a freezer 64 on it and at max it's reached 50c on a hot day here.

[i found nemo]

when u get a better cooler u can probably have a lower volt at the same freq, i'd bet. phenom II's really hate heat

edit -

if it would even take it. might just make it worse.

I got a small WC systems, but there are some results that may interest you:

At 3,3 ghz i'm at stock voltage. As soon as I hit 3,4 ghz I need a voltage increase (really small but I need one). The voltage increase start to become exponential at this point. The thing is: I need a much lower voltage increase than you, but we still need one.

(Question for everyone): At what speed are you able to run without voltage increase?
Thx for the info!
^^


And for the cpu cooler, both company made good product. You will be limited by your small form factor, so the only person that could take the best decision will be you ^^. Have a look at the review on the web, they do pretty good one those days.

phenom II's really hate heat

Phenom II's and heat are night and day. They are so easy to cool down that when overclocking you rely more on tweaking than worrying about heat. (granted you have an adequate cooler)

Hi, the stock AVC heatpipe cooler that comes with some dual core AM2 CPUs works pretty good. Look at a cooler shootout. They are better than most after market whiz bangs. Maybe borrow or buy 1 cheap on ebay. That is the only cooler that will fit in my mini cube case.

With stock voltages i was able to do 3000 ( 15 *200).. At 3200 i needed 1.31 +0.025 = 1.34

Well the cooler that comes with the 720 is just a stupid aluminium blanket.. i wish i was able to find a stock amd heatpipe cooler.. amd should send a more decent cooler with BE chips

Im running 3.553 X17.5 CPU 1.510v and my high end temp is 47. Your 57 and lower speeds. Says something about a better cooler. You might want to consider it so you can go even higher and keep the temps down.

[gOtVoltage]

Have any of you tried keeping the CPUvcore @stock and raising just the NBvid or NBvoltage for IMC to 1.3-1.35v..


My 720 will run @3400mhz with out touching Vcore and using 2000/2200nb..Stock cooler.


You may want to try it. I noticed that on my Mobo default NB was 1.1vid so i set it to 1.3vid..

This same CPU is good to 4ghz/2800nb @ 1.6v on water

[RRunner]

i have a Coolermaster Hyper 212 ... great cooler!

well i didn't try that...maybe i will....

RRunner ..vid 1.15?????? thats LOW!!!!my default vid is 1.325..

El Greco,

This information is wrong (Core Temp) and MSI 790GX-G65 has COLD BOOT in O.C.

this X3 does not pass of this (17.5x200), nor with VCORE of 1.6V

piece of s.h.i.t this CPU and Mobo.

sorry for my bad english.

[Panther57]

RRunner I am almost equal settings too you at 3.552Mhz. FSB 203. I have been using this setting for awhile now and it seems to be my personal best with stable. What voltages are you using in comparison to mine.
X17.5, 203FSB, X12 NB&HT 2432, CPU VDD v 1.450, CPU NB v 1.375, CPU v 1.510, CPU NB v 1.405, CPU PLL v 2.652, Dram v 1.80 (my sticks), NB v 1.30, SB v 1.25

Different memory but I am 9.9.9.24.2T, C1E off, CnQ Auto, SpreadSprectrum ON (I have no stability problem with on), GPU 810/1090. My temps are high 20's idle, up to high 40's under load.

I am trying to compare other results too see if any of my voltages can benefit or keep me stable if even lower. I have had higher temps with lower voltages and less stability?

Thanks.

foxconn 770 really cheap mobo and biostar 790gx better than this right?wrong..

my first 0904 720:

1.325-3
1.375-3.2
1.425-3.4
1.5-3.6

that's all with bios.with biostar 790gx 1.55-3.7
with overdrive 3.8 3.8 3.6-1.55

second 0906 720

1.325-3.2
1.350-3.3
1.375-3.4
1.4-3.5
1.45-3.6
1.5-3.7
1.55-3.8

with overdrive 3.8 3.9 3.9-1.58

on same foxconn.how about that?forget about mobo cpu is the matter.

Are you saying that NB Vid is supposed to default to 1.3v? My mobo is showing default is 1.2v... This is different from NB Core, which is 1.1v default, right?

[gOtVoltage]

Setting it to 1.3v keeps the IMC happy when overclocking while using Stock or little Vcore.


Nbvid @1.1v is default on my Mobo ,,1.2vNB on CPU is normal for a 720 ..

The NB Core is chipset is usually 1.1v

A lot of times you can clock Higher Freqencies just by Raising the NBvolts on CPU to the same or slightly lower than the CPUvcore(up to 1.55v for PHII's.




Example:

CPUvid = 1.32v
NBvid = 1.30v

I usually wont need more than 1.45nbvid for most my High overclocks.

When you are Trying to keep around stock Cpuvcore i will set the NBvid just below the Vcore Value ( Stock voltage/or default voltage).

Each CPU is different and Most will need a small bump in Vcore to get 3400/3500mhz with close to stock Volts ...It all depends on the Cooler or Cooling you use.

[El Greco]

i do not get the difference among NB Vid and NB Core..Which one do you change?

C1E off, CnQ Disable, SpreadSprectrum ON, GPU Stock. My temps are high 19's idle, up to high 32's under load.

[haylui]

my x3 720BE would be stable at 3400MHz ( 17*200 ) at stock voltage
motherboard is Asus M4A78-EM
do you guys suggest I get a better board to overclock more?

[shadow_419]

3.4ghz is about the average overclock on stock volts so I wouldn't worry about the board. You might get limited by the board at higher overclocks, but usually the cpu itself is the biggest limiting factor.

[Mavhenz]

Gotvoltage what are your temp and witch WC do you use?

1,6 volts seem really high! I'm really curious about temps!

[denice25]

not bad for 1.55v........
