How can I overclock my AMD Phenom(tm) 9650 x4 2.30 GHz?

October 31, 2015 at 01:48:03
Specs: Windows 64
I currently have AMD Phenom(tm) 9650 Quad core processor 2.30 GHz, Windows 8.1 pro x64 bit, with 5 GB of RAM. Since I play alot of online games where FPS is required the most, I wish to increase my FPS. I have seen some people talking in discussions about overclocking it to 2.6 ghz or some even to 2.9 GHz. How can I do the same?

You haven't provided enough info. What is the make/model of your motherboard & what speed is your RAM? There are numerous changes that will need to be made in the BIOS if your motherboard/BIOS supports them. If you have an OEM system (Acer, Dell, HP, etc), you can forget about overclocking.

Even if you're able to overclock the CPU, it will only do so much for frame rates. If you have a low end video card, you will either need to overclock the card or upgrade it. Or you can dial back your game settings. It won't look as pretty but it will prevent stuttering or lag. Please post the make/model of your card.

I dug up this RAM dividers chart:

Your CPU multiplier is 11.5, unfortunately 1/2 multipliers aren't on the above chart. You cannot raise the multiplier (unless you have a black edition CPU) but you can lower it; but generally you will have to work with the CPU reference frequency (incorrectly called FSB). The default frequency is for AMD CPUs is 200MHz. When you increase the CPU frequency, it will have a domino effect & increase the RAM speed, Hypertransport bus speed, AGP/PCI/PCIe speeds, etc. All these settings generally have to be lowered as the CPU freq is increased so that they don't over-overclock & crash the system or make it unbootable.

You can find a RAM frequency calculator at the following site:

I don't understand what do you mean. And if you need any more info, pls do tell, my RAM is 5 GB as mentioned earlier, and the full is usable as x64 bit is installed. I think it is DDR3..

I saw a video of AMD Phenom 9650 (same as mine) where he was playing GTA V with overclocked to 2.6 GHz, if I am able to overclock to 2.6 GHz I will be in the minimum requirement zone for GTA V, can you please help ?

I also downloaded AMD Overdrive as directed by a video on youtube, but my cores will already maxed out, is there any other way?

You have to answer my questions regarding the motherboard, RAM & video card. And as I said in my other response, overclocking the CPU can NOT make up for a crappy graphics card.

I kind of doubt an old 1st generation Phenom would be paired up with DDR3 memory (I could be wrong) so it's probably DDR2. I would have to know if it's DDR2-533, DDR2-667, or DDR2-800.

If you're not familiar with your system specs, try using CPUZ. It should be able to identify the CPU, board, RAM, & graphics card. Post back what you find & I'll see if I can offer some suggestions.

Motherboard: ASUS M3A78 EM(as can be seen when the PC boots)
RAM: 5 gigs
Videocard: ASUS GT 610 2 GB(installed this year, perhaps 7 months ago)

I am attaching a few pics:

Well done. Here's what I see:

- decent board & very overclockable

- RAM is going to hold you back somewhat no matter what you do. Your Phenom supports up to DDR2-1066 (@533MHz) but you have DDR-667 (@333MHz) so it's running at about 63% of optimal speed.

- the GT610 is not much of a gaming card. It's an entry level card that's more of a HTPC card (home theater). It's actually a rebranded GT520.

I can explain how to overclock your CPU by tweaking the BIOS settings & you should get a bit of a performance boost, but it can't make up for having slower than optimal RAM & a entry-level non-gaming card.

I'll review the motherboard manual & post back later with some BIOS setting recommendations....

Thank you! Also I request you to simplify a lil bit for me as I am completely new to this stuff. Consider it to teaching it to someone who is 10 years old!

Thanks you for your help!

Sorry, I had a lot of things to do yesterday & didn't get back until late. I'm not sure if you're familar with the BIOS so here's a brief description:

The BIOS (Basic Input/Output System) is sort of a mini-operating system for the motherboard. It's contained on a chip called CMOS (Complementary Metal-Oxide Semiconductor) which is sort of a battery powered memory chip. There's a lithium coin battery on the motherboard that maintains power to the CMOS chip...that is what keeps the BIOS settings stored in memory & prevents them from being lost when power is cut to the computer. The settings contained in the BIOS are the date/time, CPU clock configuration, memory configuration, hard drive configuration, etc, etc.

To enter the BIOS setup program, press the DEL key at startup. There are dozens of other settings but these are the only ones you should change:

Under Advanced > JumperFree Configuration:

CPU Overclocking = manual
CPU/HT Reference Clock = 250
PCIE Overclocking = manual
PCIE Clock = 100
Processor Frequency Multiplier = x10.0
CPU/NB Frequency = x7.0
Memory Clock Mode = manual
MemClock Value = 266

After changing to the above settings, Exit & Save Changes.

Your system will reboot & your CPU will be reclocked to run at 2.5GHz & the RAM should still be at 333MHz. You can verify this by running CPUZ again.

NOTE: if your system refuses to boot, unplug the power cord, open the case, then move the CLRTC jumper cap from it's normal position on pins 1-2 to the clear position on pins 2-3. Wait about 5 seconds, then move it back to the normal position again. Plug in the power, boot the system, press the DEL key & immediately enter the BIOS to correct the date/time, then when you go to Exit, select Load Setup Defaults.

Well I just did it. I couldn't find this one "CPU/NB Frequency = x7.0" so I just left it as I had no other choice. As soon as I pressed F10 for Exit andsave changes, it went to the power saving mode which it always does to restart but stopped. I pressed the UPS button and pressed it again to which it booted.

Now, both the "My computer properties" and "CPU Z" says only 2.3 GHz.....

Does the CPU/NB frequency has to do anythin with it?

It appears I was looking at the wrong motherboard manual. I'll dig up the correct one & review the BIOS chapter & post back later.
