Q9550 + P5Q-E Help!

Jedipottsy · 20 Nov 2008 at 18:06

Hey
Just got this rig

Q9550 (E0)
P5Q-E -1406 Bios
PC2-6400 OCZ Reaper 4-4-4-15
BFG 9800 GTX+ OC
Asus 900 Case
Tuniq Core Contact (blowing up with the antec case fan)
Corsair 520w PSU

I have the following settings

Code:

AI Overclock tuner		: Manual
CPU Ratio Setting		: 8.5
FSB Frequency			: 475
PCI-E Frequency			: 100
FSB Strap to North Bridge	: 333
DRAM Frequency			: DDR2-951
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

5-5-5-18-3-50-6-3

DRAM Static Read Control	: Auto
DRAM Read Training		: Auto
MEM. OC Charger			: Auto
AI Clock Twister		: Auto
AI Transaction Booster		: Manual
  Common Performance Level	: 10

CPU Voltage			: 1.36875
CPU GTL Voltage Reference (0/2)	: 0.610
CPU GTL Voltage Reference (1/3)	: 0.650
CPU PLL Voltage			: 1.52
FSB Termination Voltage		: 1.32
DRAM Voltage			: 2.20
NB Voltage			: 1.38
NB GTL Reference		: Auto
SBridge Voltage			: 1.20
PCIE SATA Voltage		: Auto

Load Line Calibration		: Enabled
CPU Spread Spectrum		: Disabled
PCIE Spread Spectrum		: Disabled
CPU Clock Skew 			: Delay 400ps
NB Clock Skew 			: Delay 400ps
CPU Margin Enhancement		: Optimized

I cant get better than 475. I'd like to hit higher, I'd love to his 500fsb which i know is a lot to ask for. But E0 is supposed to hit 4ghz to 4.4ghz right?
I ran IBT for 5 loops on the above settings and it passed. Ill post screenie later.

Thanks

have you played around with your vtt, NB and pll voltages?

I have a very similar rig, but with a Q9550 with the other stepping. I'd been running at 3.7GHz for some time and have recently switched to 4.0GHz with these settings, as recommended by Johnnylaris:

CPU Clock = 4003mhz
CPU Ratio Setting = 8.5
FSB Frequency = 471
FSB Strap to NB = 400
DRAM = 942
DRAM timing = Manual
CPU voltage = 1.362
DRAM voltage = 2.0
NB voltage = 1.36
FSB VTT = 1.36
PLL = 1.54
LLC = Enabled

Johnny has put his settings for his 4.1 'clock in this thread, which might make a good starting point for further tweaking if you haven't seen it already.

Omg, dont whatever you do update to 1406...

I was on 0704 and things were smooth. Was getting pretty decent OC results. Changed to 1406, now i cant even get 3.8ghz stable. Also in windows i cant get my nvidia card to work. It says im using standard VGA hardware. Uninstall and re-install the driver and it does nothing. GPU-Z Shows that the cards there and everything is fine...reset cmos aswell. Going to try 1201 modified BIOS from XS.

I was on 0704 and things were smooth. Was getting pretty decent OC results. Changed to 1406, now i cant even get 3.5ghz stable. Cant find the 0704 for download so im using the 1201 modified BIOS, these are better but still not as good. I had 3.8ghz right off the bat with 0704 but the Graphics card was acting up. Changing to 1201 has solved that issue but now i cant even Post higher than 3.5Ghz.

Also im running vista x64 (i use maya).

Just trying the 0901 BIOS now. Seems to let me boot windows at 475*8.5 - 1.36875 Vcore. Wouldnt let me do that before. Going to try testing now. Isnt stable with IBT though. But still lets me boot.
