UD3P and Q9550= SWEET!

[Prospector]

Just put this rig together a few days ago and I must say I'm impressed!
My old rig was an OC'd E8400 on a Abit IP35 Pro. Gave that to my son to upgrade his gaming rig.Running 3.6ghz now and finished IBT no problems.
Ran Memtest86 on the 8gigs of Ram all night no probs. Highest temp on any core was 58 during IBT. I think i could hit 500 fsb with this setup.
So far so good

Prospector, nice system you have there.. I wish i had that E0 of yours!!! I've got a C1 stepping Q9550 @ 3.83ghz and my temps are the same as yours at full load, usually between 58c and 62c...

Re: UD3P and Q9550= SWEET!

Thanks,I'm pretty sure this thing will do 500 fsb maybe not with 8 gigs of
DDR800 but I think with all the help here I can get it dialed in.

Re: UD3P and Q9550= SWEET!

Prospector, i just hit 4ghz stable!!

471x8.5=4.03/1884fsb
MCH Frequency Latch-333
Multiplier-2.00B
Memory Frequency-994
Load-Line- Calibration-Enabled
Vcore-1.3625
CPU Termination-Auto
CPU PLL-Auto
CPU Reference- aka NB GTL Reference(Northbridge Gunning Transceiver Logic) set it to 1.03v

MCH Core- aka Northbridge Voltage set this to 1.42v
MCH Reference-Auto
MCH/DRAM Reference-Auto
ICH/I/O- Auto
ICH Core-Auto

DRAM Voltage- Mine is set to 2.0v
Everything else is set to Auto...

PLEASE Check this!!! >>>
CPU Termination-Auto
CPU PLL-Auto

If left in Auto those will be WAY to high and kill your CPU, you can see the 1.85v being used by looking in EasyTune!

Please for your CPU's sake find and set a stable setting manually. Maybe >>>
CPU Termination-1.2.1.38
CPU PLL-1.45-1.6

Load-Line- Calibration-Enabled

becarefull ... lot of readingi done it's said this should be disable per intell spec. .... i know if you have this enable the Vcore voltage is very low...

Hey..i have same setup as you do and wanted to OC my rig. I am newb to OC'ing. Could you please post your exact settings? I have 4gb OCZ reaper pc8500 ram and my CPU is C1 stepping..

It only becomes a problem if you allow C1E / Speedstep to function. Those voltage spikes only happen when your chip is adjusting it's own multiplier and VID to slow down...

I have disabled C1E and Speedstep so those transitions shouldn't happen. Which means the only reason for vDroop to exist is gone...

Thanks for the heads up Lsdmeasap, i'm doing some research on it now for my Gigabyte Ep45-UD3P...

lsdmeasap, i set the CPU PLL to 1.45 and CPU Term to 1.22 to be safe... For some reason when i overclocked to 4ghz with these set to auto things were stable until i rebooted again the next day and tried to run Prime and OCCT and they both failed... No worries, i'm content with a 3.83ghz overclock that stable! I can't seem to find a stable voltage for the GTL reference nor the Northbridge(MCH)..

Lsdmeasap , you have a safe and happy New Year and thanks for all the advice..

Re: UD3P and Q9550= SWEET!

Well I'm back from my weekly route so Iv'e got my EO up to 4.0ghz and starting to test.I'll post back with some results.Lots of great help in this forum.

Re: UD3P and Q9550= SWEET!

Cool, let me know if you can get it stable and post your bios settings if you don't mind..

Re: UD3P and Q9550= SWEET!

Running Prime 95 now 3.9ghz 1.3v 460x8.5
