CPU Overclock List & Discussion Thread

re: CPU Overclock List & Discussion Thread

@S_V, Yep I will do that when I get some free time. BTW- How do you guys know that in what speed the RAM is running? Like as you said mine is running at 1066 MHz, how do you know it? What I see is the DRAM Frequency is 534.3 MHz, so how is it even running at 1066?

@ithehappy
DRAM Frequency is 534x2 = 1068 mhz.. That's how you have to do ...

DDR stands for Double Data Rate. DDR3,DDR2 rating is double the actual speed. So ram running 800MHz is running DDR3 1600.

What?

@S_V, Thanks for clarification, now I got it.

re: CPU Overclock List & Discussion Thread

i am going to replace my 10 year old machine..check my signature..is there any possibility of overclocking it? One more thing..i am a complete newbie to OC..guide me to any introductory article..

re: CPU Overclock List & Discussion Thread

dont overclock it.

re: CPU Overclock List & Discussion Thread

So I have done it. Below are the CPU-Z screens and some shots from my BIOS, please have a look at them.

I selected 'XMP' profile, and I have set the QPI/DRAM Voltage to 1.24375V (I set it coz last time when I got stable OC of Processor at 3.7G, the value was 1.24375) and reduced the DRAM Bus Voltage to 1.50V.

Should I decrease them more? Is DRAM Bus Voltage 1.50V OK? or is it still High?

This is after I select 'XMP' Profile,

Other settings in BIOS,

*img543.imageshack.us/img543/4539/photo0198s.th.jpg

and here are the DRAM Timing Control settings, are they Okay?

*img687.imageshack.us/img687/526/photo0199o.th.jpg *img233.imageshack.us/img233/462/photo0200b.th.jpg

and here are the CPU-Z shots after OC'ing,

*img141.imageshack.us/img141/6808/cpuz1l.th.jpg *img842.imageshack.us/img842/1109/cpuz2.th.jpg

Please tell me if I did anything wrong or is there anything need to be done.

and one more question, Can I use more than 1600MHz? say 1800MHz?

and oh, off topic, I was having some Winrar benchmark problem, after OC'ing the RAM I tested it again, and now I am getting scores like 3520 or above, though CPU usage isn't affecting more than 40-42%.

Regards,
Saurav.

Guys need to ask one more question, if I select XMP profile then the CPU Level Up option gets disabled, therefore I won't be able to Overclock to 3.3 or 3.7GHz, now if I select AUTO instead of XMP then CPU Level Up option gets active but at the same time Ai Overclock Tuner gets disabled. Now how can I do Overclocking of both RAM and CPU while putting XMP profile ON? Is it possible? If not then do I need to Manually OC the RAM if I want CPU Level Up to ON? and if yes, should I change the BCLK Frequency and CPU Ratio and others too like it was in XMP profile?

Ideally do not change any voltage apart from vCore unless you face instability. Keep the memory voltage to the designated profile voltage. Be careful.

Can you please explain? Didn't understand.
Is DRAM Bus Voltage 1.5V good? or should I try and decrease it more?

 

[asingh]

re: CPU Overclock List & Discussion Thread

Not DRAM Bus, the voltage for the chips. What other voltages you have for memory in your BIOS.

Yes, I won't change anything besides the VCore Voltage and QPI/DRAM Voltage. I got it.
But is 1.5V DRAM Bus fine? or should I decrease it more?

re: CPU Overclock List & Discussion Thread

What is the official rating for XMP.

 

[ithehappy]

re: CPU Overclock List & Discussion Thread

Official rating of XMP? Don't know. My RAM's default voltage is 1.65V

 

[asingh]

re: CPU Overclock List & Discussion Thread

Then just leave it at 1.65. No need to move above or below.

Yes no question of moving above, but will it be better if I decrease?

^^ Nice OC using stock cooler. What's the idle and load temp you are getting ?

Hey, that' just great - worth spending your 10 hours and 25 mins of time for this

If you get some time don't forget to post D Mark Results of that OCed beauty !

re: CPU Overclock List & Discussion Thread

@Topgear.. the idle temp. is 20-21 Degrees.. & the load temp. is around 35-40 degrees.. The temperature of the town is pretty cold too.. around 20 Degrees maximum during day and falls to 4-5 Degrees during night..

Will be adding either Cooler Master Hyper Tx3 or Hyper 212 Plus.. any suggestions?

---------- Post added at 09:26 AM ---------- Previous post was at 08:19 AM ----------

For some reason, the max. voltage was only 1.392 listed in the BIOS. I had used this board before with 720 BE, and it used to be around 1.5 V.. I think that this voltage thingy depends on the processor..

For RAM best to run it at the designated profile voltage.
