Tweaking my motherboard

post #1 of 6
Thread Starter 
I have an ASUS M4A785TD-V EVO/U3S6 AM3 AMD 785G SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard. I have it set in the BIOS to O/C the Processor at 8%. I would O/C my memory but I am not sure how to do the timings to get them right. Is there a "Guide" on how to do all this. Or just play it by ear and go for it. Sorry if this sound stupid, But..... what can I say.

My system:
Motherboard: ASUS M4A785TD-V EVO/U3S6 AM3 AMD 785G
Processor: AMD Phenom II X4 965 Black Edition Deneb 3.4GHz
Memory: OCZ Platinum 4GB (2 x 2GB) 240-Pin DDR3 SDRAM 1600(8GB)
Cards: Asus 5850 and Diamond 5850 {both 725/1000}
Cooler: ZALMAN 110mm 2 Ball CPU Cooler
System: Windows 7 64bit Professional
Case: Antec 900
Power Supply: PC Power and Cooling 750W CrossFire Ready 80 PLUS Certified Active PFC Power Supply

Hi.

Why use that option when you have a BE CPU that can rise the multiplier to overclock?

Sorry Like I said, I am new to this.

What is BE CPU?

OK, Black Edition.

I read the post that was noted in the other post. I will look at that and see what I can do. Thanks

The 1st thing that you need know is how the frequency of a CPU is calculated:

You have a reference clock (FSB on CPU-Z) and a CPU multiplier, if you multiply those two you get the frequency of your CPU.

All AMDs comes with Reference clock = 200MHz, while the multiplier change according to the CPU and frequency of it.

Here is the formula: 200MHz x 17 = 3400MHZ or 3.4GHz that is the stock frequency of your CPU.

Now, I gone explain you the difference between locked (Not BE) and unlocked (BE) CPUs

AMD has two CPU lines.

1- Not BE (Black Edition) that comes with lock multiplier. With this CPU types you need use the FSB for overclock it, but the FSB is also linked with the HT, NB and DRAM frequency. Any change in the FSB change all those values, so, in this case you need a little more work to get an overclock stable with good settings and good performance.
2- The 2nd line, is the BE (Black Edition) that comes with unlocked multuplier

With all the above info, is more easy for you use the multiplier of your CPU since you have a BE CPU, so, go to the BIOS and try with multiplier x18 or x19 with stock voltage. Test the rig for stability with prime95, LinX, OCCT or y-cruncher.

If you want go more higher or your get a BSoD, that means that you need more voltage in your CPU, return to BIOS and add more voltage to CPU in little steps.

Don't forget check your temps while the stress test is running, 55ºC or below are good temps. Come back here if you need more help.
