Overclocking Phenom and Phenom II

[Orac]

whats the v-core set at, how about temps

[clarion]

I have HP desktop running AMD Phenom II 910 at 2.60 Ghz with 8 Gb of DDR3 Ram on NVIDIA GeForce 9100 Chipset. What is the safe level I can overclock the CPU without using any special coolers???
Is overdrive enough or do i need some other S/w.- Overdrive doesn't work here as I don't have AMD 7 series chipset
New to this overclocking forum - any advice welcome

We all know programs aren't they way to Over Clock. But today we make an exception.
Install AMD Over Drive (latest edition) This only supports 7 series and up, AMD chipsets.
I have also included other driver and utility links. *Most settings for AMD OverDrive can be applied in bios.*

AMD offers true CPU OC only. This is with their BE or Black Edition Phenom I and Phenom II's. The Non BE Owners can read the above posted Athlon guide to get a feel for the over clocking process. Because the Multiplier is locked there's a little more adjustments to be made. After you have installed OverDrive, give it a walk through to get used to it's easy to manage tab system for application navigation.

To get started. Locate the preference tab in AOD. select "Advanced Mode" for more detailed over clocking. Basic mode is simplified by giving one simple slider for overclocking when you click the Performance Control. The slider moves from Default to High Performance. The High performance setting only brings the cpu to 3400mhz. I'm using a Phenom II 940BE ftw. **This program works exactly the same for Phenom I and Phenom II processors just at different clock speeds.**

Now that your in the Advanced mode, you can click on "Performance Control" Tab. You should see many more sliders. On the left side there is Core multipliers (one for each core) and HT multiplier, HT ref. Clock (or cpu FSB) and PCIe® Speed (Mhz). On the right side there is Voltage Sliders and readings. Very handy for Over Clocking.

For BE Users, The Multiplier is the easiest way to change core speeds. If you have 3000mhz 200x15 and you up the multiplier .5, that will give a 3100mhz core speed. When you adjust the slider there will be a target speed and actual speed displayed. If you want to apply the setting, click the apply Tab at the lower right hand corner. Most Phenoms can do 200-400mhz Over Clock before needing a cpu Vcore voltage increase. Voltage usage will vary between system and processor.

HT Ref. Clock increase is easily done with AMD OverDrive also. The Slider starts at the default 200 front side bus speed. The HT slider is defaulted between 1.8 and 2ghz depending on the Phenom. Phenom Agena core for example is 2000mhz stock. By increasing the HT ref. slider you'll notice the Core, HT, NB, and Ram speeds will be increased in Target Speed. Each one of these pieces of hardware will Be Over Clocked. I suggest watching the HT, being sure it's under 2200mhz to play it safe at first. Usually around 2400mhz a voltage increase for the HT/NB can be applied. Voltage needed will vary upon each chipset and system build as well. Most Ram's can handle between 30-40mhz or so from 800mhz without needing voltage increase. This also will vary between different systems. Unless AOD offers a down clock in Memory speeds, You'll have to do that in bios. I usually set mine either at 667 or 533 for even higher HT ref clocks or FSB over clocks. Learn more about Non-BE overclocking in the Athlon sticky provided for you at the top of this page if you have more questions regarding FSB or HT ref clock over clocking. There's also links for memory setup and over clocking.

Sometimes Over clocks can be done by over clocking the cores separately. This might help get a higher max OC on just one of the cores instead of all of them. Phenom Agena are common for this. Over clocking cores separately may also help aid in stability at higher core clock speeds.

There are many that OC like this.
Phenom (agena)---------------------------- Phenom II (Deneb)
CPU 0: 3.20 ghz ---------------------------- CPU 0: 4.0 ghz
CPU 1: 2.90 ghz ---------------------------- CPU 1: 3.7 ghz
CPU 2: 2.80 ghz ---------------------------- CPU 2: 3.5 ghz
CPU 3: 3.00 ghz ---------------------------- CPU 3: 3.6 ghz
Example Pic Of multi core over clock and HT ref overclock combined.
http://i269.photobucket.com/albums/j...B-MultiMix.jpg
V-core on over clocks will vary
Setting cores at different clocks seems to help keep stability.
The Multiplier will NOT change RAM timings or speeds.Thus creating true CPU OC.
Useful example of different core clock speeds.
Affinity set for Explorer core 0 3.20 ghz. (This helps keep explorer smart as can be with the most power)
Affinity set for gaming CPU 1 & 2 between 2.9 and 2.8 ghz. (Gaming lowest cause most games are graphics heavy)
Affinity set for Folding @ Home core 3 @ 3.0 ghz. (A good folding number in my opinion)

On Die memory tweaks with AMD Over Drive.

The bottom half of AMD Over Drive shows on die memory controls.
http://i269.photobucket.com/albums/j...trolMemTab.jpg
All the way from CKE Drive Strength to Processor On-Die Term A and B.
By upping Drive strengths we can move the data faster without higher clock speeds.
Lowering Drive Strengths may increase Over Clock, but nothing is confirmed.

AMD OverDrive Utility

System Information Tab: This displays Processor, Cache, mem SPD, And Memory details of the current system settings. With 3 tabs below that, Basic, Detailed and Diagram, You can really get a picture of how your system is set up. The Diagram Tab is my Favorite. When you click an Icon, it displays the specs.

Status Monitor Tab: This is where the Temps and Voltages can be viewed. There is a CPU, GPU, and Board Status tab.
Status Monitor Tab screen shot: http://i269.photobucket.com/albums/j...MonitorTab.jpg

Performance Control Tab: With 7 sub-Tabs from Clock/Voltage, Memory, Fan Control AMD Smart Profiles, Benchmark, Stability Test, and lastly Auto Clock. Clock/Voltage and Memory Tabs Are where the overclocking takes place. The rest are pretty self explainitory. Advanced Clock Calibration can be enabled in this tab as well.

Preference Tab: This section lets you chose between Novice and Advanced Mode. You can even chose which Environment Control Source. Super I/O or southbridge. You can also save your profiles under the performance tab, as well as excess the Raid expert and CCC or Catalyst Control Center.
Preference Tab Screen shot http://i269.photobucket.com/albums/j...ferenceTab.jpg
While over clocking you can Leave Clock Skews on Auto. The tolerances should be made by the bios. You will may or may not get more Over Clock by adjusting these.
Set Bios to manual Over Clock.
Depending on the board is depending the options.
Again multiplier Over Clock is gonna be the way to get the fastest CPU Over Clock results.

UPDATE:

All of the above also applies to the 7750x2 BE and 550BE x2 Phenom II. The only difference is a slightly higher clock, Two less cores, and an HT speed of 1.8ghz. This processor is great for Over Clocking. The CPU will do up to 3.1 ghz on stock voltage. In some cases only to 3.0 @ stock volts. (7750/7850BE.) The 550BE comes stock @ 3100mhz.

Overclocking HT Phenom Class I and II
This section will help guide you through the HT/NB Overclock seperately from the CPU, Unless you are Over Clocking using the FSB only. In the Bios look for HT or NB multiplier. Most boards will have one or the other and in my case Both.
Exaple A
HT OC Phenom I & II
Stock HT speed = 1.8ghz
Simply set the multiplier for the HT to x10 for a HT link of 2000mhz. This should require no voltage increase. If you set the HT/NB to x11 or 2200mhz you Will need to add voltage to the HT and NB. For a HT @ 2.2 HT voltage can run as high as 1.4 - 1.5 volts. set it there for stability. The NB will also need a voltage jump at speeds of 2.2ghz. I generally like a 1.4 volt setting.

Phenom I and Phenom II HT/NB OC quick look.
Stock HT speed = 2.0ghz or 1.8ghz 7750 BE & Phenom II
To run a HT of 2.2ghz, simply see bios for HT multiplier and set it to x11. This will give a speed of 2.2ghz HT/NB. No voltage or slight voltage increase may be required to run up to 2.2 ghz. If you set the multiplier to x12 for a speed of 2.4ghz, a voltage increase will be needed to the HT/NB. The HT can be set to 1.4 - 1.5 volts and the North Bridge any where from 1.45 volts to 1.55 volts. 400mhz OC's require a voltage increase.

Like always, keep an eye on temps. When Over volting the NB it can heat up just like any processor. HT speeds should always run equal or less than that of the north bridge. If the HT is higher, it will not boot.

Here is an example of a 9850 Phenom OC with a 400mhz HT/NB oc.

Phenom II 940 OC. Used with AMD Over Drive!

Specs:

Mother Board: Asus M3A32-Mvp Deluxe Wifi W/Mempipe
Cpu: AMD Phenom II 940 x4 3.0ghz AM2+
Random Access Memory: Muskin DDR2 1067
Cooling Type: Liquid Cooled
Video Out: 4850x2 Crossfired with 4850 (tri Fire)

MoBo Bios Version: 1502
Ati Driver version: Catalyst version 9.2
Testing OS: XP64 and Windows 7
AMD Over Drive Version: V 2.1.6

The cpu is stable stock @ 3ghz and a voltage of 1.35v stock.
My first attempt will be an OC on stock voltages. Which I might add are higher than I expected.
So on that note I will lower them to 1.3 volts. I will do mostly multiplier OC's for this.

PS.
I want to thank EOCF admins, mods, and members for making this thread a sticky. Also Big Thanks for the thread title name change.

first bit of advice would be to downlaod some software for stress testing and tempurature monitoring. i use HWmonitor for temps and prime95 for stress testing.

nobody will be able to tell you how far its will OC, let alone on pre-built system its a trial and error thing. next bit of advice is i always getting a better cooler, stock ones sometimes struggle to cool a stock CPU under load. even just some after market TIM can make a difference

Your mother board probably won't let you over clock the cpu any ways. You own a HP..... OEM boards are not equipped with the proper bios.

A common OC for that chip. What voltage are you using currently for 3193mhz?

[moody58]

stock volts 1.30 aod says my target speed is 3193 current speed is 3667. all my current spds are faster than target spds.is that saying it's running like a 3.6?

Update your bios and then re-install AOD.

[moody58]

1213 is current bios i'm using volts at 1.3125 was sitting at 3209/1.3125 fsb 207 stable for about 30 45 mins b-4 blue screen crash dump

Add some more v-core at the current clock speed. Try 1.3500v.

[moody58]

thanks i'll try that

No problem.

The 1109 Ram speed is consequence of over clocking the FSB. Your NB, HT, and Ram all get over clocked when you do it via FSB.

its the little paperclip in the editor.

very good oc, what cooling?

Best investment to overclockers is real good cooling. My cooling setup is around $300

I sold my 940 to a member who diced it and got 4.5Ghz so I feel this OC is real good at 4.220Ghz.!

wow.

wow.

do you know what specifically causes bad validations? i see them every so often, for seemingly no reason.

and i just can't pull the trigger on water. i know, i know, but i'll just flat out admit my fear of electrics and water. later, i MAY invest in the corsair d-50... i understand it won't be much better than the air i have now, but it WILL get me used to water in my case for a relatively low price.

[bambihunter]

Water isn't bad at all... Just take your time, double, triple, then check again for leaks when you first build it. Then, check it in a week. Then, you are good for 6 months... I won't use it on all my machines, but for my performance PC's it will probably always be in there until I get brave enough to try phase.

[ShrimpBrime]

Added the Phenom II unlock experience thread at the top of the OP. AS well as a quicky advise about thermal paste and burn in time and what it's basically done for.

Any one burn in their cpu's after a quick re-seat lately? I'm currently in the middle of one right now after Ocing a 9950BE 125w . Now back to the 940 again.

Additional Comment:

Also added PSU's for today's computer's by davidhammock200 at the OP as well. Very important to have a power supply that fits your needs!

OK so the specs to get his in bios at stable cause on the 9750 seems hard I find just change the fsb to 225 the vcore to 1.376 leave the ram at default but lower the ddrtiming speed to 375mhz(should say 700mhz if yours has menu that calculate the x2 factor since its ddr2)then doesnt blue screen since even my kingston didint liek to oc for the phenom ...and leave everythign else on default and put the multipier on 12x but i would assume default would work too, mines set to 12x----THIS IS ON STOCK COOLING WITH 2 EXTRA CASE FANS 10MM
I have yet to donwlaod a cpu monitor but bios was runnign about 63 so i owuld say in windows 7 maybe 65-67 idle but i do believe this chips should not fry till 90+ if they still make them like they youst to and my last 2 amd setup I could get hot runs and still fine performance and life since they are all still alive somwhere lol

for the persons post above mine I would try this similar setup in regards to your core being uped more wouldnt worry to mcuh unless your gettin over 66 in bios idle also i belive i had mine up to 1.4250 at 2.7 jsut got it to work with lower voltage so chose that. thnx!!

Additional Comment:

Actually to go with the above Im now using 1.34vcore and fine....wouldnt recommend doing htis with a 450 watter lol blew mine right the **** out last night running gta IV all on high haha plus my vcore was like 1.425 forgot to put back donw haha neways yeah stock cooling, all setup monitoring idle is 59c and mine was like 1'c less before so Deff good overclock neone got ne opinions or better setup for stock cooling and 9750 oced!!!

59c at idle is too hot. Your cooling is not working properly. At all stock settings, the stock cooler should be able to run 40-45c idle and up to 50-55c fully loaded. The stock cooler is designed for running stock speeds. And notice how much the word stock is in the last sentence.

For over clocking, you want over sized cooling. You have/Had a nice over clock besides the cooling issue. You'll get more mhz if you can get it running much cooler. That is my advise to you. That cpu has a max of 60-70c recommended running temp. depending on what sensor your looking at.
