Your southbridge voltages should be 1.05V and 1.50V. At stock anyway. It's extremely unlikely they'll need any extra voltage.

Thanks stn0092

I actully run quite a bit cooler than that when blending, however it's when I run large fft's Everests mobo temp reading goes up virtually in line with the hottest core

Anyway at least now I know its not just mine

Well I've reached 445x9 with this Q9650 at 1.232 idle (w/LLC) and 1.216 load. Temps stayed at 50C or lower (of course I only primed for 30 minutes).

Should I stay with this clock and my RAM at 890 while trying to lower timings? Would 500x8 and RAM at 1066 with 5-5-5-15 timings yield better performance? I know the answer would be to just test it myself and see what it scores. I just wanted to get some feedback and share my setup info.

I need to double check some of these settings. I'll edit the post when I have them all correct.

VID is 1.2250v

InTeL · 01-28-09

biomech download core temp it shows on that little nice software

Vinovvi · 01-28-09

Hey guys, I'm having issues getting past 425 FSB with my Q6600 vid 1.275. I'm currently running F6 bios, right now I'm at work so I can't post any bios settings but is it possible that I've hit a FSB wall with this chip? Also within windows Everest apparently doesn't show the CPU temp. sensor. Is this a problem with the F6 bios? Thanks in advance

silvergoat · 01-28-09

I just got mine, testing for stability now. It kept crashing until I turned the RAM timings down. I have mch at 1.2 CPU at 3.2 (q6600), vcore at 1.3315, RAM v at 1.8. AHCI is disabled.

some problems are that the RAM shows as PC 6400 but I purchased PC 8500 (when I turned the timings to those of the 8500 it doubled in stability so I think it's being incorrectly read by the software)

My CPU shows to be at 3.6 in the control panel and everest home, but in the bios and with the easy tune 6 it shows as 3.2.

Depending on when the test stops, I will try to increase vcore, drop mch to 1.15, and increasing the voltage on the corsair xms2 to 2.0 from 1.8 as it shows on cpuid

any advice

Here is my setup (as of tomorrow when I get the stuff in):

Core components:

- Intel C2D E8500 o/c to ~4.0gHz (see below for settings)
- GIGABYTE GA-EP45-UD3P motherboard
- Corsair Dominator 4GB PC8500 DDR2-1066 (thinking about using the $40 rebate card towards another 4GB)
- Antec Truepower Trio 650w Power Supply
- ATi Radeon 3870 HD 512MB PCI-E video card
- Two 500GB Hitachi Deskstar P7K500 7200 RPM hard drives running in RAID 0

Case:

- Antec 900 Gaming Case, Black Steel

Cooling:

- 200mm case fan, top mounted
- (2) 120mm case fan, front mounted
- (1) 120mm case fan, side mounted
- (1) 120mm case fan, rear mounted
- Xigmatek Dark Knight 120mm CPU cooler
- Metal heatsink for hard drives (not sure if it will fit in case yet)
- Corsair Dominator Airflow (three fan cooler that comes with Corsair Dominator RAM)
- Arctic Silver 5 thermal compound for CPU

Software:

- Windows Vista x64 Ultimate (possibly dual boot with Ubuntu Linux, Beryl desktop, and Wine)

Overclock settings:

- 500FSB x 8 = 4.0gHz
- SMM = 2x (RAM will be running at 1000mHz)
- Mem settings = 5/5/5/15
- CPU Vcore = 1.3625v
- DRAM voltage = 2v

With the case I'm trying to decide how to arrange the fans. The 200mm fan is going to be blowing up and out. The two 120mm fans in the front will be sucking in towards the MB and CPU. The 120mm on the rear will be blowing out. Trying to figure out what to do with the 120mm fan on the side (in or out). Heatsink fan pointed towards the rear and out.

Anyone see a problem with these settings? Do I have to flash the BIOS or is the revision that comes with it going to be fine?

I'm jealous of the people that say they got at or above 4.26gHz but I was advised not to try to do that because it's borderline the edge of what the system can do...but I saw some people doing 500x8.5 with 1.408v and getting 4.25gHz...sounds yummy if you ask me. Think that 1.408v will be safe to run for a long period of time?

That setup looks strangely familiar to someone elses.

Overclocking is working your way up through the trenches. You will be VERY lucky if your pre-rig settings will workout for ya. Go slow man and be thorough. Thats the true path to a stable rig.

orbiter · 01-28-09

Just got my UD3P up to 4.2GHz however it's not stable under load really. It'll even boot into windows at 4.45GHz

I reckon my system knows though or it can see the mouse curser heading towards the Prime button as it packs up immediately then

I think that maybe my ReaperX's are giving me the problems though because I'm getting quite a few errors in memtest.

Yomny · 01-28-09

thats a hell of an overclock man, what FSB and what votlages fo MCH, cpu pll and cpu vtt if you dont mind sharing?! Congrats
