Problem overclocking with new build

post #1 of 10
Thread Starter 
Hello all,

Just put together a new build using an ASUS M4A88T-M motherboard with an AMD Phenom II 965. I've been heavily into PC's for 17 years but I'm VERY new to overclocking. When I go into my BIOS, if I try changing the multiplier (it goes from 4X to 11X I believe), even starting at 4x, it won't go past the Windows start up screen. What am I not doing? I only want to overclock to probably around 4ghz. I'm not much of a gamer, I mostly play old games that a Pentium 4 would rock. If it helps, this is what I'm running:

NZXT Phantom 410 case
ASUS M4A88T-M m/b
Phenom II x4 965
16GB G.Skill 1333 ram
G.Skill Sniper 120 GB SSD
WD Velociraptor 10,000rpm 150GB HDD
Corsair H100 Liquid cooler
XFX Radeon HD 7850 Black Edition
XFX 650 watt 80+ bronze PSU
Windows 7 64bit

Welcome.

You'll want to read the Phenom II OC'ing tutorials below for a proper means to OC your CPU. FWIW, 4 GHz. is a healthy OC for a 965 BE, not just a minor tweak.

Did you run stability testing on your new build at the default frequency? If not this is the first step. Also run memtest86+ to be sure you're starting from a solid baseline before OC'ing. Otherwise you may just be wasting time and energy.

You'll also need to keep the CPU temp below 60C under max load like stress testing. 55C is the preferred max temp by many people for Phenom IIs to prevent errors however.

OC'ing is a journey of exploration filled with much trial and error as you are trying to get your hardware to operate at a frequency it has not been designed/approved to function at. wink.gif

Ok, overclocking to me is like trying to read a book in Spanish after only taking Spanish 101.

What stability tests should I run? I should also note that I'm new to Windows 7, up until today, I've ran XP.

CPU-Z also says my 965 voltage is only .992 volts .... that seems low for what I've seen from others stock voltage.

As you'll read in the above Tutorials, you'll need to disable Cool & Quiet, C1E, etc. to run the CPU in power state P0 which is full voltage/max frequency.

For stress testing many folks run Prime95, OCCT and Linpack as a minimum in addition to Memtest86+ overnight or for at least 10 passes.

Awesome, I disabled Cool n Quiet, etc, then fooled around with the multiplier. I could almost get it to Windows with the multiplier at 20x (I figured out it went higher then 11x if I just scrolled down, duh) so I tried 19.5x, got it to windows, ran Prime95 and went to blue screen in like 1 second. So I kept going down the multipliers and at 18.5x, I'm at 3.72Ghz, 1.36 volts and running around 45 C @ 100%. I ran Prime95 for 2 hours. It's a shame I couldn't get it to go more. I fee like if I knew more about overclocking I could tweek little things individually to get more out of it. But I'm pretty happy ... for now .... any idea's on what I could do to get it to go more or am I SOL? I read in one of the posts that every AMD chip is unique, at least to the point of overclockability.

Aside from this being a somewhat flawed assumption (these features only downclock the CPU when it is idle and of course provide full speed/performance as it is needed! At a heat level/power consumption/fan noise benefit), disabling these is not actually necessary for improved stability or even ability to overclock.

I would say you could put more volts into your CPU and still be safe so you can make your OC more stable. You will want to run Prime for 12hrs straight with no errors before you should trust that it is running fine. I wouldn't go over 1.45 volts for now; but I have gone into the 1.5+ range with no problems. And once again, you need to keep tabs on your temps, 60c + is a no go.

Putting more voltage would be unwise as long as, as with this setup, there is no VRM cooling.

The XD has spoken....That's not an overclocking board..
If you don't mind used..this an OCing board for cheap here:

^That will take your deneb to higher levels than what you're using.
