Ok so now i am interested in overclocking a little. Besides i think being a tech i should know how to do this. I have never doen this before so is there a good detailed guide i can read. I am using amd overdrive, and did get to 3.3 from 3.2 by increaseing the HT ref clock from 200mhz to 205 without changing the cpu multiplier. But i do not want to damage anything.
I never overlclocked and need some help advice.
 
In a nutshell, I simply changed the multi from 16x to 19 or 20x, and you should have an easy 4ghz. That might require a small voltage bump, most of these do 4ghz easily on near stock voltage. Also don't forget northbridge overclocking, I simply changed the NB multi from 10 to 12 and the 2400mhz NB clock makes a decent "free" bump again with little or no voltage increase.
 
hmm i was just looking and my cpu multiplier only goes to 16.
So to get this straight...

Uploaded with ImageShack.us


The red arow is the reference clock?
And if thats it then the green is my core speed increase from 3200mhz with a Ht ref clock increase of 10mhz
Now i just slowly worked my way up to 225 HT Ref Clock and my cpu is at 3600mhz and seems stable for the basic 3d mar testing free edition. i did notice that during the test the first video the return to proxycon my fps were 100+ during the sence with the guy and minigun and the screen really flickered. But when it got to round 2 of that video with what ever settings enabled, the fps barely broke 22, and the flickering was gone... All this at 3600Mhz

Okay so with stock cooling, ye si still have stock will be ordering a hyper 212+ i think. I ran the stability test with Amd OD with the Ht Ref clock at 225 and my cpu core at 3600Mhz and it passed the 8 minute test with a max temp of 58c, i did notice i have an exhaust fan set to intake, so the damn thing is pulling hot air in and down abpve the cpu.

Okay so i just rebooted so i can fix that fan beng assbackwards. and the speeds got clocked back down.....to 3200mhz

Once you get settings you want to keep you should be setting them in the BIOS so it boots that way. 58c is getting hot, 55c is considered Max ideal temp. 63c is considered high Max. My Arctic cooling a64 freezer pro keeps mine around 51max using Intel CPU burn test. Overclocking by multiplier is a lot easier than what you are doing BTW.

Are you talking Cpu Core multiplier or CPU NB Multilplier which is red out in the CMOS items box.
Cause if it is the CPU core then, unless i have to change via bios, my cpu is max x16 by amd it seems.
And i am looking at getting a after-market HSF before i make these changes permanent. I think the hyper 212+ is the one.
 
The CPU core which shows as 16x Max in that screen.......it looks like you don't have a BE CPU. Is this a prebuilt system? There are actually four different 955 AMD processors. A 140w. a 125w BE (unlocked multi). A 125w non-be and a 95w non-be. At any rate you should be doing overclocking in the BIOS, if you can't go above 16 in the BIOS then you don't have a BE CPU.
 
Mine is the 125w version custom built be me pc.
I bought a 955 BE from newegg. This is my order information......

Wow.

These things are recommended to stay below 55C? That is awfully low, considering Intel's Bloomfield doesn't temp throttle until 100C.... I'm glad I read this before starting, as I thought my safe temps would be up to at least 85C or so... :eek:

I bought my stepson a new rig (in pieces, we are building it together) for the holidays. Started out with a Phenom II X2 555 BE, which I plan to unlock cores and then overclock.

I discarded the boxed cooler as the X2 coolers look like absolute trash. Wound up with a stock cooler from a Phenom II 965 for free which I plan on using to begin with. Hoping to be able to get at least 3.6Ghz with this cooler, and buy him a beefier cooler later on.

Does the above sound like a reasonable plan?

I would think it can hit 3.6. I hit 3.6 by increase ht ref clock to 220. and hit max load temp of 58. Thats with stock HSF and some dust which i am going clean out when iu get home,
 
Kk that is what i thought. So i need to increase the cpu multiplier to something like x18 or something and see if i get stable (provided i get a aftermarket HSF) then increase the voltage as needed by only 50mv at a time?

Now so i do not start a new thread. Does anyone now how well the Hyper 212+ performs? My current temps with a little dust(will be cleaning today) are 36c average idle on cpu. I was getting before 32c average. So if i install the hyper 212+ with some artic silver 5 or something as good, could i expect to get high 20's theoretically speaking of course? Also i have 2 exhaust fans on top pulling hot air out and up away from components and have a side intake and back intake. I more than likely will buy a new HSF and a couple more good 120mm fans

I can't wait to start building this thing now :)
 
Do not use amd overdrive. Go in the bios.

Do not overclock the hyper transport, not even 1 mhz. Causes instability and does not increase performance. Do a search for my user name, you can find several posts I have written on these processors.

With the stock heat sink go into the bios and do this:

Reload factory defaults first, save and exit.

Enter again.

Change all of this:

AMD Cool N Quiet: Disabled
AMD C1E Support: Disabled
AMD C1/3/6, etc if you have these: Disabled

Go into your overclocking menu:

CPU Multiplier: 18
NB Multiplier: 12
HT Multiplier: 10

FSB (BCLK): 200

Do not change anything else.

Make sure your ram is running at factory speed. Do not overclock it yet while attempting to figure out the processor.

Go into your voltage menu:

CPU Vcore: 1.425
CPU NB Voltage: Start at 1.175, go up to 1.225 if you need to

Do not touch any other settings. See if this boots into Windows.

You may not need that much CPU Vcore, but the factory heat sink will have no problems cooling that amount.

You need to keep the CPU temp, not core temp under 60 C. You will not break it, it will just shut off.

No point in buying a heat sink if you want to stay between 3.6-3.8. These processors run very cool. You do want to make sure you OC the northbridge if you can, there is a great anandtech article on the performance increase from this. In starcraft 2 then keep a 1090t at 3.2, and just raise the NB from 2.0 to 2.8 and it results in a 16% performance increase.

You can not break these processors as far as I have been able to figure out. I have a 955 at home at 4,125/2,950 northbridge at above "max reccomended voltage" since September.

WOAH BUDDY PLEASE do no take what i did into consideration for overclocking i am a dumbass at it. I never done it before and only found interesting articles related to it and will be doing What quitesufficent has instructed me to do. He/She undoubtably has much more background on this and the AMD OD software is crap,after reviewing it..., and you could cause system wide damage beyound repair if you take what i did and apply that... DO NOT LISTEN TO MY POST ABOUT HOW I GOT 3.6GHZ please!

IF you do, use my expirence for your own overclocking. I take no responsibility whats so ever. As i have said i am not an overclocker i have never done it. And if i mess up and you do what i posted about doing i am not liable

Haha! No worries. I have been over-clocking since the 286 days when I made my 12Mhz 286 run at 16mhz.

I was just trying to see if my expectations of what I can do with this chip were reasonable.

I will of course go through it methodologically and test it step by step when I get around to it :p
 
ok i just didn't want something to happen. XD
I am at work so i can't even test quite's advice yet :p

This is correct info as well.... I didn't see this at first.

If your multiplier is locked. You need to up the FSB or BCLCK in the bios, then turn the Hyper Transport Multiplier down to keep it below 2000mhz total.

Zarathustra[H]

3.6-3.8 is a pretty reasonable expectation out of any 555. There are plenty at 4.0+
 
is there a way to up the nb other than the multiplier because im ocing my 965be and there aint a nb multi in the asus bios Asus M4A78 Plus or is there even a point to oc higher than 3.8ghz since im using 8gigs of 800mhz ddr2 ram

Yes the factory 965 cooler is more than enough for 965s to hit 3.6-3.8, so I don't see why it would be any different. AMD really sets these up to run from the factory
