955 BE overlocking

Clear cmos first if i'm was u (or reset default value from bios)... (I don't like the freq/bus speed upped to 240 it will effect your ram, It's quite tricky with freq)

The easiest way is up the multiplier by one do stress test and up again till u get 3.8 Ghz (x19 multiplier) or stop if the temp rise to high or there is instability....

most 955 will reach 3.8 without need to tweek the voltage or feq but not every chip is same.....

edit: after u get stable speed u might try to increase NB freq to 2200..

Thats the easiest way, the hard way is by droping to the lowest stable voltage and start from there but i'm not recommend for first time...

There also a way by increasing the bus frequency/speed but it even more harder to do since it will effect everything in the mobo (so if auto set it to 240 is way to high IMO, mine just 201)

I cant change the mutiplier, its locked at x16, i changed it back to stock 3.2ghz

Temp was never an issue, ran prime when it was 3.8ghz for about 1 hour ( i know not enough time) and wasn't getting over 51c on the temps

issue is the ram wont go to 1333 and the multiplier is locked

i will go get all the info so you guys can help me, gonna write it down when its set to 3.8ghz

something wrong .. why BE locked multi ??? phenom 955 be

The bus speed to 240 is way to high for me, since bus speed not only effect the cpu it effect the ram and pci-ex (NB & SB bus). your ram can fried if the setting wasn't right with that speed... (x6.66 at 200 = 1333, x6.66 at 240 = ____, u can guess it)

Try clearing cmos/reset default bios value, see if the multiplier still locked...

Golden rule in O.C (someone told me  ) is step up a little then test, step up again and test, repeat that again and again......

The locked multi maybe caused by auto O.C feature......

That what i'm suspecting......

Edit : It's strange for Black Edition since BE means unlocked multiplier

u may wanna check your CPU series (OPN number) and stepping.....

changed back to factory stock

bios is back to defualt

For ram, where did u get number 960? (cpu-z?) if x6.66 runing in 240 bus speed it's equal with 1600 (above 1333)

btw if the ram is run at 1600 and it's stable, it might easier leave it auto O.C-ed since it already get to 3.8 with 1600 ram and 2400 HT....

detail CPu maybe is AMD Phenom II X4 955 (95W, rev. C3, non-BE) .. that's  

Bios says 960 where it would normally say 1333

also thats with out o/c i was told to go back to defualt

cant change the multiplier

Do you have AXTU? I have the ASRock 970 Extreme 4 and it comes with AXTU. It's a real time OCing program. If bios won't allow it try to see if AXTU will change the multiplier. If it doesn't then your chip is defected, I'd guess.

already posted it a few up http://valid.canardpc.com/show_oc.php?id=2449821

it also has a max cpu ratio of x16

The only way to sure check is by reading the chip OPN code, HDZ............. (It's also writen on the box, in tray one we will need to read it in the proc)

from the cpu-z it seams the bus speed drop to 6.13, that not right try to set it to 200 (normal)

Can it be the motherboard that is defected? Reading the processor wrong and what not? Maybe if you reinstalled bios?

HDX955WFK4DGM i got this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... it was oem

If your chip indeed defected then it's need to RMA...

If it was not BE (or somehow locked) the only way to do is by increasing bus frequency.... (same as the auto O.C. do)

Ahh so it is the chip  

The chip you got was a 95TDP one and the other 955 is a 125TDP, I gues theres your difference because the 955 125watt is BE.

Then it's clear...

my sugestion is just let the auto O.C do it for u...

u already at 3.8 Ghz with 1600 ram and 2400 HT speed at first, I'm just not realize it at first.......

well that sucks, is there a way to overlock it still then?

yeah with the FBS, as was done before.

how do you tell if it is running at 1600? from what i looked it was running slower then 1333

Mistakes were made on my parts, shoulda gone with the i3 2100 and a p67 then later upgraded to a i5 =( o well first build too   i learned from my mistakes

Well If u are courious, u can set the buss speed manualy, but keep the mem timing in check

make sure the memory multiplyer is at x6.66 so when x6.66 at 240 = 1600

do memtest to test the stability of the ram at O.C -ed speed (1600)

thanks every one for helping   i messed up =( should have linked everything at the start

well 955 at 3.8 is much better than i3

(It's four cores!!!, it works better if u like to run couple apps at same times)

ehmm back to topic...

Go to the bios and check the memory multiplier is it x6.66 [1333], 1333 at bus speed/FSB 240 is equal to 1600....

Edit: I'm not familiar with Asrock Bios (never own one), asince i'm can not give percise guidence/names in bios i'll let the other ..........

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

this is the ram that i have (so i dont make the mistake of not linking things and we end up in an hour long post about a none be 955 ) i will go check that right now

thats my cpuz when auto o/c is on amd overdrive says it is at 3.8ghz and i dont think the ram is at 1600 or 1333

also with the auto o/c i havnt done a long stress test like more then 1 hour of prime95

Think this will work?

G skill rams had good rep, (Mine also G skill)

It's not strange that your 1333 (value) can run at 1600....

So The Auto O.C feature (your first tried) is already done a good job with your hardware......

the only thing need confirmation is the ram speed (try get cpu-z data on auto O.C)

If u wanna learn about oc..
try manualy set (increase little by little and lot of stress test)

the bus speed at 240 (target),
nb frequency at 2200 (target),
ram timming at CL7/8 1T (target)
ram speed at 6.66

right there

Not going to argue about intel vs amd.......

well try to confirm it by runing cpuz with auto o.c state....
or if u can manually set the bus speed at 240 with mem multiplier at x6.66 then the memory run at 1600...

(if it's not stable try at x5.55 = 1333 speed)

edit: err more confused with the gpu-z, maybe because i'm not familiar with asrock auto o.c feature (is it increase/drop the bus speed related with the workload?)

http://valid.canardpc.com/show_oc.php?id=2449868

the bios are kinda weird there is no ram multiplier i did how ever post the auto o/c stat of cpu z

i just got a blue screen a few seconds ago... thinking 3.8 isnt stable kinda weird since i didnt get blue screen when i ran prime for a 1 hour and now i did after about 15 mins of browsing the net

?

alright, gonna run prime 95 now for a couple of hours

Hmm Lets do this step by step...

load bios default/clear cmos...
check the bus speed/FSB is it at 200?
- if it not set it as 200
check the ram speed is it 6.66/1333
- if it not set it as 6.66/1333
let the other at auto...

do stress test........
if it pass

try up the bus speed by 1 mhz and do test (also down the mem speed to 5.55 for now)

if it pass the test increase the bus speed again and test

if it reach the target 240 then we will go to ram later....

edit: if it do not reach 240 than it's okay go to last stable and down 1 mhz.. (the chip hit the wall and need voltage raise, but don't do that [not recomended])

btw O.C via FSB is one of the hard way of O.C. it will need a lots of patience.........

alright im running prime95 right now

Um...

It's maybe to late now but are anyone warn u about O.C.?

There is always had a risk it will fries your hardware.. so make sure u will not regret it later..

the decision to O.C should be made before u start O.C -ing

The bus speed at 200 with ram at 6.66 will give u default/non O.C value....

edit: i have to go to bed now (It's already pass midnight here), well good luck ......

yeah, they say dont turn the Volts past 1.5v so i cant damage the cpu, the ram i can just rma and same with the mobo! if anything goes wrong? well its something i have to learn if im going to build a computer, if i wasnt i would of gotten a pre assembled pc

amd overlock says voltage is 1.27 but cpuz says 1.432v kinda weird unless amd overclock is telling me something else says cpu vid 1.2750v

Yeah knowledge and experience can be very important...,

I'm started getting sleepy here hehe...

I will check how it goes later... 

alright, take care! and thanks alot all of you guys for helping me!

There feature of Amd called Cool and Quiet it will increase and drop voltage of the core based on workload...

it can disabled but i'm like turn it on so it will run at lower speed when there is nothing to do...

edit: mine never go over 1.36v but it might be diffrent as each mobo had diffrent vrm implementation..... (1,4v is a little bit high but still in safe margin i'm guess)

oh ok, well its about 36 mins into prime95 and so far 48c is max i passed 2 test on the 3rd one right now, and the voltage is 1.432v on cpuz and 1.2750v on overdrive while prime95 is on, ill check bios later to see which one is correct

how long should i run prime95? 8 hours?
