OverClocking AMD PhenomIIX4 970BE

[vikas12]

hi guys need help again however now im able to get 4ghz in 1.45v in vcore but when im trying to go for further like rasing current muiltiplier to 21x its fail at windows start up however i have tried to put more voltage like 1.5v in cpu vcore still it shows blue screen in windows start up

current bios setting can be seen in below pics






pc config
AMD Phenom IIX4 970 BE
Gigabyte 990fxa-ud5
Coolermaster Hyper 212+ HSF
Antec 300 PC Case
AMD Fire PRo v4800 1GB GDDR5
16gb Corsair XMS DDR3 1600MHZ 1.65V
400 watts PSU





i want to get my cpu to 4.2ghz stable enough to render my 3dsmax and maya scene my aim to overclock is to increase rendering speed and save my time at moment if im running only 3d rendering it runns fine but at soon as i start my after effects app after sm testing it shows blue screen my temps are 59-60 degrees at full load

 

[vikas12]

also i have tried to apply sm stable OC settings too still fails

Those settings are what worked for others, they may not work on other chips, what is the lowest voltage you can run 4GHz on? the heat from 1.45v is whats killing you there, at least in part,
get it booting on as low a voltage as possible, then come back and we'll see about pushing it to 4.2GHz

[vikas12]

hmm ive tried it booting it with by default voltage also it wont boot to windows startup screen it restarts automatically also now in current position im able to get 4ghz super stable by pushing vcore voltage to 1.47 how do i can get high frequncy by low voltage

 

[Motopsychojdn]

Its strange that you need so much Voltage just for 4GHz, my 975 gets that with just 1.325v,
check out the black edition overclocking guide at the top of the section, it goes into much more detail than I can at the moment,
but if you lower voltage as much as possible, then your temps will come down, also, is all your ram matchd sets?
because if not, that can cause issues and mismatched ram can be a ah heck to set up right
Moto

 

[vikas12]

yes my rams are matched here is the cpuz info abt cpu position:,

 

[vikas12]

are u also using gigabyte 990fxa-ud5 motherboard?

well about my bios setting which i have made to get 4ghz is follows as


muiltiplier =16x
Cpu Host clock = 250
Northbridge frequency = auto 2000mhz
ht link width = auto
Ht frequency = auto 2000mhz
Dram manual mode
Dram frequency = 5x 1333

System Voltage Manual
cpu voltage = +0.075v
Dram voltage =1.650v

 

[Motopsychojdn]

Nope, I'm on an AsRock 890fx Deluxe five, but I'm seeing your problem straight off,
you have increased the ref clock and lowered the multi,
set the ref clock to 200, leave it there, set ram timings manually,
start with 1.325v and set the multiplier to 20,
increase the voltage whenever you bsod, but check amd's site for your chips voltage limit, not nominal volts, maximum, should be around 1.55v
also check the sticky up top for black edition clocking, it can explain things better than me
Moto

 

[vikas12]

it wont boot in until the voltage is normal or set high amt then normal

until i put +0.75v above normal it wont boot in also i have tried to raise nb frequency to 2600 and db voltage to 1.2v from 1.100v which was default not sure this i have kep vcore voltage to 1.450 instead of previous 1.475v which was stable and nb frequency and db voltage was auto

according to this pic
http://1173.photobucket.com/albums/r594/vikas_mondal/Untitled1.jpg
your voltage @12v is reaching 12 without any stress test

so first try these
use all default settings
(cpu 200x17.5@ 1.4v,
ram 1600 9-9-9-24-41-2t@1.65v
nb 200x10@1.175v
ht 200x10)
and run furmark+prime95 small fft at same time and see temp and voltages (post the pic)

btw which psu you are using _(model) and how much is its current capacity at 12v (see lable)

 

[vikas12]

 

[truegenius]

psu looks ok,
but some readings are not correct, so use hwinfo64 to check.

You can run ram at 1:4 (means 1600mhz) @ 9-9-9-24-trc41(instead of 34)-2t , but cannot overclock that ram without hitting more dram voltage.

So, now First set every thing at stock
(cpu 200x17.5@ 1.4v,
ram 1333 9-9-9-24-41-2t@1.65v (to make some room)
nb 200x10@1.175v
ht 200x9 (to make some room))
then use 200x20@1.475v and then increase fsb to 210 in increament of 1mhz, and check if it works

@OP

FYI, most of the phenom II's hit 4.0 GHz at max, anything beyond this will provide no benefit and will be unstable as it requires too much V.Core and custom cooling.

However, 4.2 GHz isn't hard to achieve, but make sure you'll be unable to get beyond this.

Try 200*21 with VCore 1.52 and up the NB Volt by +0.25

 

[truegenius]

@mal
:lol:
you are sticking with 'stock voltage only'

 

[Motopsychojdn]

You can get 4.5GHz Ilsaml, but you have to be very, very lucky, with good cooling. most I've seen top out at 4.2 as I've mentioned elsewhere but I can't understand why Op is struggling here so much,
If I were him I'd just settle for the 4GHz and call it a day
@true, start at stock and up as needed, but at least you can track what you've done
Moto

 

[truegenius]

@mal
is it stable at those settings?

 

[truegenius]

or can grab a 1090t for Rs9000 (180$) and overclock that to 4ghz

 

[truegenius]

@mal
because my thuban wants 1.475v to stable at 4g
so moto is your brother from another mother

 

[vikas12]

ok igot stablilty in 3.9ghz just at stock voltage

Unfortunately, that "Good Cooling" refers to a very custom water cooling loop, Since Saint19 was marvelous in OCing and he couldn't get 4.5 GHz stable, there's no luck. Also...It will be beneficial only for that 4.5 GHz you say, beyond this you need LN2.

 

[Motopsychojdn]

on eBay in US cheapest 1090T or 1100T was like $225 a few days ago, do not remember which one.

Can't remember which chip, or which day?
Honoured to call you Brother man
@Op, take it easy, save those settings as a profile, that way you can always come back to them as a known stable point to start from

what about my proposal?

 

[truegenius]

idle temps are what.?
how's it feel.?
also reset you RAM timings back to 1600MHz..

(listen to mal~) as I wave my magical wand... And paparapa majinboo

:lol:

 

[vikas12]

what about my proposal?

trying to get higher clock in low voltage if not by this way then go for ur proposal
