ASUS P45 P5Q-PRO + e8400

post #1 of 5
Thread Starter 
Ok. So I bought this CPU > http://www.overclock.net/main-compon...0-4-1-1-a.html

and paired it with a P5Q PRO. I am having trouble getting 4Ghz stable.
I am not new to OCing but newish with LGA775 and have no real idea of what I am doing. Whether I should be adjusting NBv, SBv, CPU GTTL, etc etc.

I want 4Ghz stable on my stock cooler since temps arent too bad.
Once i upgrade cooler Ill be aiming for 4.4/4.5 hopefully.

Can someone with a similar setup post their exact BIOS settings? (I know each CPU/mobo is different but I just want a starting point)

Thanks!

Full Rig >

ASUS P5Q-PRO
e8400 (E0 stepping) (1.25 VID)
2x2GB Kingston Hyper X 1066Mhz 5-5-5-15 (2.3v)
750w PSU (not generic, solid unit)
GTX 460
Stock cooler ATM
Latest BIOS (2102)

Cheeeers!

Here are 4.05GHz (450MHz FSB)for you to try out..

FSB freq = 450MHz
DRAM TIMINGS=5-5-5-15 (the rest on AUTO)
STRAP=AUTO
DRAM freq= 900MHz (very important for stability,I have P5Q Pro and The same Kingston HyperX 1066MHz 2x2GB RAM and I can't make it to work on 1066MHz on this motherboard)

DRAM STATIC READ CONTROL = DISABLED
DRAM READ TRAINING = DISABLED
OC charger=Enabled
AI Clock Twister= Moderate
AI Transaction booster=Manual
Performance Level= 10
9x multiplier

Vcore=1.xxV (what Chip needs to hit 4.05GHz,add a bit if you crash)
CPU GTL = 0.65x
PLL=1.54
FSB voltage=1.26V
DRAM voltage=1.90V
NBv=1.26V
SBv=1.2V
PCIE/SATA voltage=1.60V
CPU & PCIE Spread spectrum=Disable
CPU & NB skew=AUTO
NB GTL=AUTO
Load Line Calibration=ENABLED

All options in CPU Configuration set @ DISABLE and CPU MULTI @ 9x..

Testing methodology:

1. But first test these with 6x multi with P95 LARGE FFT for at least 6h and stock Vcore as your CPU would be running @ 450x6=2.7GHz..

2. If you pass Prime95 LARGE FFT reboot to BIOS upp your Vcore and set MULTI to 9x..

3. If it doesn't boot keep adding Vcore untill it does..

4. Then in Windows test 450MHz FSB x9= 4.05GHz with Intel Burn Test 20runs w/ max RAM and if you crash then just upp Vcore and test it again..

5. If you pass P95 LARGE FFT 6h & IBT 20 runs then you're ROCK SOLID..

KEEP YOUR CORE TEMPS UNDER 75C IN ANY STRESS TEST..

P.S.: Since you're on stock cooler I would recommend you not to be stress testing untill you upgrade your cooling..

CHEERS..

I was hitting about 66-70c in P95 running 4Ghz but was getting errors on the workers, everything else was auto though, now Ill adjust them. Thanks

Bump
Managed to get 4.1Ghz stable at 1.256v (under load) by disabling LLC
Going further once im off stock cooler.

yes, keep LLC off.. dont forget that the ramsticks may need more than 1.8v and this could lead you to the conclusion that you need more nbvoltage

set margin mode to performance and the ram setting [lighter,light,modarete,strong,stronger] to moderate with 450 fsb.

cpu gtl to 0.63 could help also.. the higher the oc the gtl needs to be lower, not higher afaik but i lost the link to that thread.

nbvoltage till max about 1.4 should be ok for any oc you want.. i would not go higher for everyday use..

im just throwing in some clues to the comment kingT added.. his post is good.. rep+ him! :O)

edit: try keepin the ram ratio 1:1.. anything higher WILL cost you much voltage to get it stable! goodluck..
