Trying to learn...Please help!!

Hey everybody Im pretty new to the overclocking world and am In need of guidance. I am trying to overclock my system to as close to 4ghz as possible but all I just dont know what to be boosting voltages on etc as there are so many options!!

Heres my spec

Asus P5Q-E Mobo, (2101 BIOS)
Corsair TX750w PSU,
4x2GB OCZ Reaper 8500 1066mhz,
Q9550 (E0 stepping), Xigmatek Red Scorpion S1283 CPU Cooler (OCZ Freeze Extreme Thermal Compound)
Gainward Radeon HD 4850 512MB GDDR3 (x2 crossfire)
2 SATA 300 drives

At the moment I have settings like this and cant get past 10 minutes with prime 95 x64!!


AI Overclock tuner : Manual
CPU Ratio Setting : 8.5
FSB Frequency : 400
PCI-E Frequency : 100
FSB Strap to North Bridge : AUTO
DRAM Frequency : DDR2-1003
DRAM CLK Skew on Channel A1 : AUTO
DRAM CLK Skew on Channel A2 : AUTO
DRAM CLK Skew on Channel B1 : AUTO
DRAM CLK Skew on Channel B2 : AUTO
DRAM Timing Control : Manual

5-5-5-15

DRAM Static Read Control : AUTO
DRAM Read Training : AUTO
MEM. OC Charger : AUTO
AI Clock Twister :AUTO
AI Transaction Booster : AUTO
Common Performance Level : AUTO

CPU Voltage : 1.3
CPU GTL Voltage Reference (0/2) : 0.67
CPU GTL Voltage Reference (1/3) : 0.65
CPU PLL Voltage : 1.52
FSB Termination Voltage : 1.28
DRAM Voltage : 2.10
NB Voltage : 1.3
NB GTL Reference : Auto
SBridge Voltage : 1.2
PCIE SATA Voltage : 1.5

Load Line Calibration : Enabled
CPU Spread Spectrum : Disabled
PCIE Spread Spectrum : Disabled
CPU Clock Skew : AUTO
NB Clock Skew : AUTO
CPU Margin Enhancement : Performance

Any help would be greatly appreciated!!
Thanks!

Welcome Dan!!!

Here is a great HOW TO guide found in this exact same section for you to read...: http://www.ocforums.com/showthread.php?t=515316

But while you are reading that, what is your stock voltage (VID) on that chip? Can be found in Coretemp or Realtemp (MaxVID in Realtemp).

For now, just set your memory so its running 1:1 with your FSB (so 400Mhz, 800Mhz DDR).

Thanks for the welcome and the super fast reply EarthDog!!

HAve read through the guide and changed a few things around..

Prim95 has been running for 40 mins now error free.
Real temp - max temp 48c.
The max VID is 1.3625 (from intel site) and 1.3 (from real temp)
I can see the auto settings have the ram set at 400mhz 1:1 now.

 

[EarthDog]

Yeah, your stock voltage is 1.36 so I would make sure its not going below that number. You will likely need to increase vcore as you push that overclock.

I thought it was better to have lowest possible voltages to keep temps down?
If this is stable for 6-8 hours should I increase FSB or Memory speed??

Cheers

Like that guide says, one thing at a time!!! So with that in mind increase the FSB.

Again as I stated, leave the memory alone for now. Frankly you should just leave it at 1:1 to your FSB anyway as running it at its rated speeds isnt going to net you any tangible performance.

All I said was you will likely hit a wall soon and have to increase your vcore "as your overclocks increase". But yes you are right, the lower the better for temps.

Sweet Prime95 blend test passed 2hrs!
Gonna increase FSB now by 25 and run OCCT for an hour and see what happens

 

[EarthDog]

Maybe a bit smaller increments would be best...

10. If it boots, then another 10. If it doesnt than you have to back off or adjust some voltages.

You may want to stick with SMALL FFT in P95 as your memory is running well under stock and it shouldnt be the issue. Small FFT concentrates more on the CPU.

Right so tested for 3 hours with OCCT linpack without error. Just to be sure.
Bumped up the FSB by 20 gonna run OCCT again now while Im in college.
So the blend is for ram and processor then yeah?

Thanks
