M3A overclocking

[SocketMan]

yes i did, from 1.25V ( i believe is stock) to 1.265V
i dont wanna raise it more, i think 55C on load is heaps.

but i didnt touch the NB or SB voltage they're on auto
and i didnt touch the NB multiplier its auto,

only thing i done is raise CPU MUlti to 11x
set RAM speed to 667
increase voltage to 1.26V
and set FSB to 245.

but im sure i can get more than 2.7 on this phenom guys.

You left the NB multi on auto ?
if so then it would go from 1800mhz (200x9) to 2205mhz

Try setting it to 7 manually, and see if you gain something

[SocketMan]

Any confirmation if this works for regular AM2 cpu's as well ? I can only give about 1.5 volt to my sempron

I think that "mod" is for Phenom's NB which had it's own powerplane,unlike the K8.
So I would say no it wont give your K8 or K10 cpu more voltage.

[SocketMan]

my buddy has this board (asus m3a-h) with 4 x 2gb g.skill pc6400 sticks...

would uping the northbridge voltage help out a little since there is so much memory?

stock is 1.3v right? maybe uping it to 1.3125 or 1.3250?

I've heard someone (with a different board) that he had to increase the NB voltage when running 4gb or more since the load is greater on the IMC and NB, so I think it would help a little

[SocketMan]

Oh, cool thanks for the info!

Does anyone use speedfan?
I do, and temp1 gets hot, like 50C, while core stays cool at like 24C.
I have felt around the mobo, and the cpu HS is cool but the small black one that says ASUS get warm.
So is temp1 for the black HS? Whats under it and why does it get so hot?
I have changed the grease for the big HS above the video card to AS5 but when I tried to do it for the black one I could not get the clips off.
I think I would be able to get better oc's if it was cooler.
What do you think?

The black HS is over the South Bridge (SB600) which shouldn't get too hot (warm is ok)
The main concern here is the "little" silver HS over the NB
(top of the PCIe slot) that one gets burning hot

Ok ill try that SocketMan - thanks for the reply. however last thing i remembered was setting the NB Multi @ 11x same as CPU.
ill try 7. shoudlnt they be identical?

common guys there must be SOMEONE here with a Phenom 9750 and an ASUS M3A that culd give me some values

No not identical and I think most people here have the 9850be,
you know what they say: once go black you never come back

[mr1c3man]

hehehe
ok SocketMan, im running the NB-Multi @ 7x and the CPU-Multi @ 11x
with an FSB of 245 its running @ 2.7Ghz

what do you suggest i do without killing my RAM
decrease multi increase FSB or vice versa.
i tried CPU-Multi @ 12x and FSB @ 240 = 2.88Gz but crashed prime

Well the good thing about k10 is that your ram speed stays
at whatever you set it at,and does not change with different multi's .It will increase as the HTT (fsb) speed is increased,
so you could try setting your RAM to a lower divide (DDR400/533) and slowly increase the HTT(fsb).
Keep in mind thou that you're in the area (mhz) where Voltage increase is a "must".
Also many people with 9850be get stuck in the same or lower
mhz "area".

[mr1c3man]

Ok well im running it as you sugegsted earlier:
CPU-FSB = 245 (showing 2.7Ghz in CPU-Z)
NB-Multi = 7x
CPU-Multi = 11x
Vcore = 1.26v (opposed to 1.25v stock)
RAM=667 (showing 410Mhz in CPU-Z)

Ok so if i decrease my RAM down to 400.... and increase the FSB - woudlnt that degrade my RAM speed?
also what voltage is a MUST to increase? the RAM or Vcore?
I dont think i can add anymore on the VCore its running Idle @ ~37C and Load @ ~57C (running prime for 4 hrs)

[informal]

Hi mr1c3man

Did you try to increase the Vcore at all?Please try to get the chip to 1.3V and verify this with some software tool,like Everest,Speed Fan or Hardware monitor.
57 degrees is not that much,watch the temps not to cross 65C.

[mr1c3man]

hi Informal!

OK The temps i got readings from CoreTemp 0.99? is that unreliable?
because my heatsink isnt as good as yours.

Ill try 1.28V and creep up to 1.3
But plz tell me what other settings i need to set... i.e FSB, NB-Multi, Multi, etc

[informal]

SocketMan gave some good suggestions.Any reason why you run the 11x multiplier for the CPU?12x can't get you to 2.7ghz stable?Since every time you drop the CPU multi the greater the chance you can't hit higher OC since the board is HTT limited(can't push higher HTT).Try using the 12x muliti.
AS for memory speed,Phenoms do work better with higher mem. speeds but try to keep the memory around 800Mhz,cas 5.Also set 2T timing mode to ON in dram configuration,don't leave it at auto.Disable all spread spectrums.Try to raise the NorthBridge voltage after you hit a wall again(don't know if the board has NB voltage control since i use X2).
Also,set memory manually to cas 5-5-5-5-18-25.Set dram cycle time to 127ns for all slots.
If you still have some issues,try disabling CoolNQuiet in BIOS,maybe it will help some.
But mostly you are very likely limited with you Vcore.Try to get it around 1.3V or 1.35V.The B3 revision starts to get to higher clocks around 1.4V but you are limited with your temps.

Good luck!

[mr1c3man]

yeah my board has NB & SB Voltage control.
ive tried running it at 12x multi and set FSB slightly lower, it crashed but ill try again with 2T set to ON rather than AUTO
when you said keep memory at 800Mhz, does that mean showing 400 in CPU-Z? (as in adjusting the FSB)?
Im gonna have to give the 12x multi another shot... ok so ill leave RAM @ 667 or drop to 400?

PS As SocketMan said, without increasing the Northbridge yet, the heatsink is burning hot. lolll

Try using 12 multiplier with 225Mhz HTT(equals 2.7Ghz).Set memory to 667Mhz in BIOS.Also the HT overall speed can be equal to or less than NB core clock speed but must NOT be greater.So the total speed CPUz reports for HyperTransport(called "HT Link") must be same or lower than "Northbridge frequency"that is reported under memory tab in CPUz!
You can use AMD Overdrive and see all the clocks in question very easily:

[mr1c3man]

ok so if i set my core Multi t0 x12
do i leave the NB multi at x7 or up it to x10 or x11?

Also Thanks Informal & SocketMan for your suggestions,
ill try the 12multi
ill try the manual timings u sugegsted
ill try increase the vcore bit more =)

[/QUOTE]

NB multi?? Is that just for phenoms?

[mr1c3man]

hmm no idea..i just have that option.

[mr1c3man]

Socket & Informal, this is ridiculous,
i just got home to try the core multi @ 12 and NB multi @ 10 and ran SPEEDFAN instead of Coretemp
the IDLE TEMP IS 42-44C!
What the hell?
is this ok? i put a small amount of heatsink paste and i got the CoolerMaster HyperTX2. this chip is crap i reckon

[LIKMARK]

Nb multiplier applies only for K10.

Speedfan reports the right temps, yes, 40 + temps at idle sounds right to me, what voltage are you running?

[justapost]

@mr1c3man: What is the max vcore you can choose in the bios with the 9750?

Umm i ran 1.27V as opposed to 1.25V
and the load temp shot to 65C and it froze on prime

@mr1c3man: What is the max vcore you can choose in the bios with the 9750?

its unlimited, i can go up to like 2.5V or sumtin stupid

basically what i found was:
setting CPU multi @ 11
NB Multi @ 7
DRAm @ 667
FSB = 246 brought it to 2.7Ghz stable

now i set the CPU multi @ 12 and NB multi @ 10x and decreased the FSB, it was unstable..

[LIKMARK]

It sounds like quite high temps i must admit, I got 57 degrees under load with my 9500 at 1,4 vcore under water. A reseating of the hfs might do good?

I'd love to which one is correct cause only, one thing has come close too my bois. H/w montior which 36C in bios and 45C on 1.55Vcore.

I use AOD sometimes. but it's the same temps as core temp 0.99.
core temp says I idle at 39-41C. sometimes 36C-37C.
speed fan say 23-30C idle

[justapost]

Can be your PSU's 4pin 12V rail can not provide enough current. That was my limit here with the 9850BE. I repoorted that a few pages back.

The chip is not crap, its just 125w. It will idle that hot.
My x2 4850(45w) oc'd to 3ghz idles at 25 and max is 45.
