Overcloking my E7300 with a P5QL-Pro

January 16, 2011 at 08:15:27
Specs: Windows 7
Wanted to overclok my E7300 to run at 3.2 or 3.0 Ghz and im not that familiar with this.
The Procesor in bios by default is at 266 x 10 Multiplier. with :

CPU Spread Spectrum = Enabled
PCIE Spread Spectrum = Enabled
Intel SpeedStep = Enabled . From what ive read i have to disable those. I personaly have to do it to change the Ratio if i want to change it.
Also my Ram is Kingstone HyperX Running at 5-5-5-15 1066
FSB : DRAM is 1:2 . From what ive read in other answers and such is that ratio should be 1:1 , i dont realy know how to do this.
Also if when i modify` the FSB 300 to get 3.0gz my Ram freq goes higher aswell about 1200 or something.
Is there any way to OC my Processor while keeping the ram at 1066. And if there is now way to do this , when i overclock my processor and my ram will be at about 1200 should i step up the voltage at RAM by a tiny bit?Atm voltage is the normal one for 1066 . 2.2 if im not mistaken.
Also does the multiplier affects the OC setup so much ? if so what would be ideal in my case.

You need to lower the CPU multiplier, underclock the RAM & increase the FSB. The faster the FSB, the better the system performance.

Here's your CPU specs, notice the voltage range is listed as 0.8500V-1.3625V:


You have a decent board that supports up to 1600MHz FSB, so to get the best performance, that's what you should shoot for. The following settings should allow you to run the CPU at 3.2GHz at 1600MHz FSB with the RAM running in sync at 1:1 ratio.

AI Overclock Tuner - manual
FSB Frequency - 400
PCIE Frequency - 100
FSB Strap To North Birdge - 400
Dram Frequency - DDR2-800
Dram Timing - auto? Use CPUZ to determine the timings for DDR2-800.
CPU Voltage - auto? You may need to increase the voltage slightly. Use CPUZ to determine the default voltage, then go from there.
FSB Termination Voltage - auto
Memory Voltage - auto? If you have high voltage gaming RAM, set the voltage to the manufacturer's spec.
North Bridge Voltage - auto
South Bridge Voltage - auto
PCIE Spread Spectrum - disabled
CPU Ratio - 8.0
C1E Support - disabled
Max CPUID - disabled
Intel Speedstep - disabled

Run CPUZ before overclocking. This will provide the default CPU voltage & the CPU timings. After overclocking, use CPUZ to check the results.

...and use SpeedFan to verify temperatures.

You have to be a little bit crazy to keep you from going insane.

mickliq thanks for the info , was actualy realy helpful.
Also about the programs i have them all.Orthos , Prime95 HWmonitor , CPU-Z and all that.

"i still dont get one thing if i set the fsb to 400Freq i get 1600Mhz fsb ?"

Yes i googled that one out and found myself. Anyways guess i was editing my post exactly when you replied :)
Ive done lots of research and actualy understand now how it actualy works even tho i was rather new to overcloking in general.
I understand now` its about Quad Data Rate so if the Frequency is 400 then FSB is 1600 and also the ram works on Double Rate. got it perfect now (I hope).
Now..From what i understand its perfect to run it at 3.2ghz so i get the full out of it. Ok so , result :

Ive put the Ram at 800 from 1066 with the 800 timing 5-5-5-18 ,modified fsb to 400 ,PCIE freq 100 put north bridge 400 got 3.2ghz and normal voltage showed by CPU-Z was 1.16 (at 2.66Ghz ). Ive gotten up to 1.21 since below that it were only crashes and stuf and when i got to 1.21 my pc purely stopped working , it started and 1 sec after automatic restart . I had to reset my bios by removing the pin and battery , no problem there took 2 mins. But uhm why did this happen ?O_o

PS: I kinda` did something that i maybe shouldnt do , First ive put the ram at 800 and then changed FSB to 400 but as i was changing this my RAM changed and ive put it to 1066` instead of 800?! and rest is what ive said earlier. rr after Rr :))
Now the question is : I put my ram to 800 and then its get modified in bios when i change my frequency and leave it like that , or i change the frequency and then leave the ram at 800 ?
And another 1 . I have actualy 2 spread spectrums PCIE and PCU as far as im aware of disable both ?!
Ive read a lot of posts about this and in some posts said that crashes in my case can be due to Ram failing . Maybe changing the ram back to 1066 after setting Freq, at 400 wasnt a good ideea after all =)

Ok so lets see to see if i fully understood.
My Frequency atm 266 which means 1066 FSB
My rams atm run at 1066 but which means its divided by 2 so its 533 so ratio is 1:2.

Sorry for beeing annoying , most of those are probably trivial to you :)

There are 2 ratios that are considered optimal, 1:1 & 1:2, but 1:2 can only be hit under certain circumstances. Each BIOS works a little differently so I may have been incorrect about the RAM setting. Some have the CPU & RAM frequency linked, others do not. The trick is to check your settings with CPUZ. Use the memory tab to see which speed the RAM is running at & what the ratio is. Try all the settings I listed above except put the DRAM freq to DDR2-533.
