Asrock 870 Extreme3 & Athlon II X3 450 Overclocking

I have the ASRock 870 Extreme3 motherboard (see below for full system specs) and I'm about to go about overclocking. I unlocked the 4th core without problems. I want to do basic overclocking and use stock cpu fans, etc. I'm looking for a little better performance, but nothing extraordinary. What's the best way to OC the system? What tools should I use to stress/test the settings? The memory settings are on auto but don't currently match the specs listed for the memory.

My new PC =

Processor: AMD Athlon II X3 450 Rana 3.2GHz Socket AM3 -- 4th core unlocked

Nice rig you've assembled. Congrats on unlocking your x3. Temps will be your limiting factor.

First you need to pour over your manual and familiarize yourself with your bios. Second get your memory set to specs as you eluded to. Pages 42-44 covers that ground. I believe you will need to change "Multiplier/Voltage Change" from Auto to Manual to get at those settings.

You want to get a baseline on stability with the unlocked core as well as temps on load. You should run a stress test program like you asked about for a couple hours. Programs like:

"Prime95" on blend (32bit or 64bit,which ever os you are running): http://files.extremeoverclocking.com/file.php?f=205

"OCCT" on linpack: http://www.ocbase.com/perestroika_en/index.php?Download

"Linx" w/max available memory: http://www.xtremesystems.org/forums/showthread.php?t=20...

You can monitor temps while stressing with programs like HWMonitor: http://www.cpuid.com/softwares/hwmonitor.html (unlocked you won't have core temps, but I believe thee overall cpu socket temp will be reported under the Tmpin0 sensor on your ASRock, which ever sensor climbs as you begin stressing.

Occt can be configured to report socket temps under Options/Settings by selecting tmpin0 from drop down screen for each core.

Max safe cpu temp according to amd is 75c: http://products.amd.com/en-us/DesktopCPUDetail.aspx?id=... (I wouldn't want it to get up over 65c when stressing)

If you have any problems while stressing, clear your cmos and go back to an x3 and try again.

Also if possible, open three separate instances of CPUZ showing the cpu,memory and speed tabs and post a screen shot for us so we can see where your at.(you can also press F5 while viewing each tab and a bitmap will be save in the folder you've installed cpuz in) Include what ever temp monitoring program as well showing your max temp

Should be quite cool & snappy at 15x240MHz and 1.375v'ish (maybe even lower). Your RAMs will be running spec 1600MHz (6.667x240) and the IMC/NB at 2400MHz.

15.5x240 at 1.375-1.4v would not be a surprise. Might start to get a bit toasty with the stock HSF.

I'm going to need to do a little more reading on this topic. I tried to approximate your settings as close as possible, but prime95 caused crash every time. Here's what I mean regarding as close as possible.

If i changed the Overclock Mode* from 'Auto' to 'Optimized' i could not set the set *CPU Frequency* to 240MHz and PCIe to 100MHz. Those options were greyed out. I had to change the OC mode to CPU,PCIEe, Async. Then I could set the CPU Frequency* to 240MHz and PCIe to 100MHz. Chaining the remainder of the settings was per instructions until it came to the Memory clock speeds. There was no option for 667. Based on the provided settings the memory options were 480, 640, 800, or 960.

I turned off the unlocked core and it still crashed.

The bios provides server OC profiles. I tried the 5% and 10% profiles. They were closer to the settings you suggested, but those memory clock options were 460, 613, 766, 920 and 440, 586, 733, 880. I'm not sure which settings cause the memory clock speed options to change, hence the comment for additional reading.

Any additional suggestions?

The 'optimized' with *Overclock Mode* must only work with the AsRock OC utility. Did you try the other Overclock Mode setting to see how it functioned - the 'Sync' one? I'll fix that in my notes if we get this worked out.

If you drop the *CPU Frequency* back to stock, does that fix the memory clock options?

In this case I think you would select '733' --- which is 667 plus 10 percent. What I don't understand is the way AsRock is presenting this option to you.

If you reset everything to stock, try FIRST setting the memory clock option to 667 if it is available to you.

Yeah, I tried reset everything to stock and then tried setting the memory first. I then had the 667 option. After selecting 667, I changed all the other settings. Then went back to the memory setting and it had changed to 800. The memory I have is DDR3 1600, so I wonder if that is why it went back to 800? So regardless of the memory clock speed being presented I should pick the one that represents the same ratio as the 667 if 667 isn't an option?

I didn't get a chance to stress it after setting to stock, selecting 667 and then reconfig everything else. I will try that shortly.

I am curious why the CPU Frequency Multiplier is being changed. I didn't think the Athlon II could be overclocked by changing the frequency multiplier because they are not BE. Doesn't OC'ing Athlonn II involve increasing their clock frequency?

I went in an manually set the memory timings to spec. I'm still a little confused about Memory clock. If the memory is DDR-1600 shouldn't we be using 800 instead of 667?

You have to drop the memory clock to stay spec ram speed when you raise the system clock. [:jaydeejohn:5]

8(.00) x 200MHz = 1600MHz

6(.67) x 240MHz = 1600MHz

Math & Magic. I get it. ;) 

I'm trying to read up on this topic. So, I keep the memory timings the same regardless of the memory clock?

How do you like your Rosewill Destroyer case???? I have one coming to me this week from Newegg and i was wondering if it has a good amount of room in it for a midtower case.

I'm embarrassed, but I goofed. The case is Rosewill Challenger. I just built one computer for my kids and am in the process of building a second. First case is the rosewill challenger. I really like it. Second case just arrived today. That's the Destroyer. Of the 2 cases I think the Challenger is a better case. Challenger was on sale when I bought the first one and the destroyer was on sale the second time. I don't have the MB or PSU yet so it's hard to tell how much room. So far I like the challenger better.

Here's the results so far. Aside from setting the memory timing to appropriate specs, I have just been adjusting the FSB and leaving everything else set to Auto. With 3 cores enabled the max CPU Frequency I can get is 220 and core temp using prime95 is 47. Idle core temp is 19.
Core temp at stock settings and prime95 is 44.

Memory voltage spec is 1.5V. If i try to manually set voltage I have option of 1.477 or 1.54. There is no 1.5v option. Should I use 1.477 or 1.54?

I'm having some trouble linking my cpu-z shots.

See cpu-z screen shots for stock settings: http://image76.webshots.com/176/0/14/1/2822014010100675...

See cpu-z screen shots for 220 CPU http://image71.webshots.com/171/5/37/95/235053795010067...

I haven't found stable CPU frequency for 4 cores enabled. It's somewhere between 210 and 220.

Any recommendations thus far?

I got this board and processor, i turn on the ucc things wont reboot or shut down properly unless i hit the reset button. I also thought it would try to unlock the fourth core automatically if I turn on the turbo ucc. Not sure if it tried or not so since it didnt seem stable i leave the turbo ucc off. I did though overclock the processor to 3.5ghz and the ram to 666mhz through the bios. Not fully sure if I did things right, but I ran prime95 and memtest86+ and all is stable at those settings. Does anyone else have some suggestions for me for what to do with overclocking the cpu and ram more or unlocking the fourth core? I'm new to this stuff and this is the first computer ive built so any tips are appreciated, thanx...
