try running RAM to the closest speed it can with the closest timeing, but remember, ram under 1.65V. as for uncore, i need to do some more research, till then im sure sam and 100% sure nucknfuts can help.

I got lazy and just dropped the multiplier on the ram for now. Wish I bought higher speed RAM now, 1600Mhz is fairly limiting when OCing.

I'm not sure exactly how QPI stability is for LGA1366, but I haven't experienced any problems with the default QPI multipler at 4.12Ghz on my i5.
Russ: The C0 for the Q9450 wasn't a newer stepping, it was an older stepping, the first of the CPUs to appear, I don't think there were that many of them.

For some reason I can't my 930 stable past 195x20. Raising the QPI/VTT and Vcore didn't help, am I missing something or does it really want more voltage?

AISmoked,
I maxed mine at 3.94GHz, but you couldn't run it that fast 24/7. Everyday running was 3.83GHz using a Freezer 7 CPU cooler. A case with good airflow, is a must!

Haha yeah i think i got that cooler at the moment and right now its clocked at 3.84 and has been for a few months runs ok i know there supposed to run hot mine is about 47C so it aint that bad as far as i know i have good airflow and a good case, thanks .

You ought to check the temperatures when the CPU is under load. Sitting at the desktop CPUs don't get that hot, but under heavy stress such as a video encode or gaming, you will see pretty toasty temps with a 3.84Ghz Pentium D on a small cooler like the Freezer 7.

Lol i have never classed that as a small cooler lol then again apart from this i have only used stock coolers, and i can only check my CPU Temp in bios so i cant find out what it is under load.

Omega: I don't have the TX750, that's not my PC. Not sure why you both seem to think it is... :S The 750W TX had four PCIe connectors, whereas the 650 only has two.

Sam, I'm comparing the HX and the TX 750. I think I know the answer though. And the HX750 probably is worth the extra dough just with the extra efficiency alone ;) Not to mention the 7 yr warranty, and extra cables :D I'm gonna buy it!!!

The HX 750W may or may not also be quieter than the TX too, I've no idea, I've not tested it.

Hmm haven't used a TX series but my trusty old 550VX has been going for almost 3 years and it certainly is quiet like the HX.

Red_Mah: look back a few post, I posted some working profile settings for a i7 930 @ 4.0 and 4.2GHz but for starters you need a little more vcore, try up to 1.29 @ 4.0 & oor 1.33 for 4.2GHz. I would try to keep QPI/VTT to under 1.4 for now. mine loves 1.35 (BIOS) 1.33. effective. Dont forget the ICH/IOH voltages, see my BIOS setting few pages back.Or PM me for a detailed sample.

Russ: The C0 for the Q9450 wasn't a newer stepping, it was an older stepping, the first of the CPUs to appear, I don't think there were that many of them.
QPI link Data Rate (freqency) can best be left to the lower of the available option such as 7218 if DDR set to 1600 at BCLK 200. Auto generally works fine for this but there is never anything wrong with locking it in manual to get used to manual settings.
As for the QPI volts, the more you craank up closer to and above DDR1600 you will need more QPI volts such as 1.3~1.35+ but since the MCH is on die, use w/ care and try to keep around 1.4v or less. I can't speak for the guys who do go well over.
UCLK Frequency should be no less then double your effective DDR rate. Ie: 3204MHz if DDR set as 1600MHz. I like to add an extra 0.3 to 0.4 over for smoothness so I use 3809MHz @ DDR1600 but depends on Mobo and other voltages and most importantly, the CPU (since MCH is internal it is limited to batch quality).

Edited Oops, I misread & quoted D-840 specs, you meant D-940
Everything is same below for D-840 but you have no multi unlock here so are stuck w/ the 16x but they run cooler and can go a lil higher on air. Of you are lucky to get the (C1) stepping even better, less vcore at higher clock to 4.2GHz. I ran one as 266x16 in 1:2 DDR1066 3-3-3-8 (4.26GHz). I'd say 4.10GHz is a sweet spot once you dial in the mobo settings it likes.
prescott Dual D840:These could be good OC's (BO was good) to 4.2GHz on air (good strong air) but really depends on Mobo and chipset. I had the worst of luck on few nVidia for Intel Editions at lower 14x multi to at or above rated clock w/o some added vcore. But as soon as I moved to my ASUS P5WDG2-WS Pro !975X it went smoothly. I strongly suggest a big tower cooler to and you will more then likely get 4.0GHz daily w/ minimal vcore increase on the 16x. These did well on P35/P55, X38/X48 as well. I had no personal experiences w/ it on !965 but i'm sure they did equally well or pretty close.

Hey NuckNFuts :P i am a OC noob and i may get annoying lol but i dnt know what you were talking about, i have some specs for you here
I have B1 Stepping (dont know what that it)
in bios i have these options
CPU Frequency normally at 200 but profile overclock at 20%
DRam Frequency 667 or 800MHz
1.8V Dual Over Voltage
VTT_CPU Over Voltage
1.25V Over Voltage
1.5 Over Voltage
motherboard is an ASUS P5KPL-AM IN/GB
Northbridge chipset is Intel Bearlake G31
I have 2 A-data Premier 1024 MB DDR2-800 sticks of ram
CPU idle is around 42C
Stress test with Everest raised it to 51C monitoring with Speed Fan
Hope you can help me
Thanks

Thanks Nick; forgot about your early post, I'll go back and take a look tomorrow. Also I'll post details about what I'm at now if I can't get it working. First thought is jumping from 1.267v vcore to 1.29v seems like an awfully large increase just to gain 700Mhz (and something I'd like to avoid).

Jeff: I see a lot of people moan actually that the 550VX is nowhere near as quiet as the 450VX. The 550 is also a CWT not a Seasonic, the red shroud on the inductors being a big giveaway :P
AISmoked: P31 boards are exceptionally weak for voltage regulation and hardware in general. I would advise you not to overclock a Pentium D very far on one or you risk burning out the board.
Maw: Using an i7 has you lost for what Vcore really means! Even in the Core 2 Days you'd have to go from 1.25V to 1.4V plus to get 30% overclocks on most steppings. Here you're pushing 40% with almost no Vcore increase at all. Don't be scared!

Yes I am aware of this but under idle conditions both are inaudible over the rest of the system. Considering that particular PC is idle nearly 24/7, this means very little noise anyway. I believe in Corsair as well so I can't imagine the CWT units have unreasonable quality.

I agree. A P31 may be fine for OCing the low wattage budget C2Ds, but they also use half the wattage of the Pentium D. The Pentium D is also famous as one of the hottest running CPUs ever so be mindful of your temps.

CWT make good units, they just aren't typically as quiet or efficient as the Seasonics, is all.

Nick, What PLL did you list in your previous post, QPI or CPU? Based off the voltage I think it's the CPU but I wanted to be sure before messing with it.
Below is what I'm at now and what I was trying for. No reasonable voltage increases seem to be working so let me know what you think before I raise them closer to the limit.
Stable:
BCLK Frequency [196]
CPU Multiplier [20]
DRAM Frequency [1568]
UCLK Frequency [3136]
QPI Frequency [7056]
DRAM Timing Configuration
1st Timings [6-8-6-20]
2nd & 3rd Timings AUTO
Load-Line Calibration [DISABLED]
Intel Turbo Mode [DISABLED]
Voltages
Vcore [1.267]
QPI [1.1]
IOH core [1.1]
ICH core [1.1]
DRAM Bus [1.64]
DRAM Ref [AUTO]
Unstable:
BCLK Frequency [200]
CPU Multiplier [20]
DRAM Frequency [1600]
UCLK Frequency [3200]
QPI Frequency [7200]
DRAM Timing Configuration
1st Timings [6-8-6-20]
2nd & 3rd Timings AUTO
Load-Line Calibration [DISABLED]
Intel Turbo Mode [DISABLED]
Voltages
Vcore [1.281]
QPI [1.215]
IOH core [1.4]
ICH core [1.4]
DRAM Bus [1.64]
DRAM Ref [AUTO]
TIA,

Hey yeah i know they run hotter than others but as far as i know it can handle a bit more...was just wondering if anybody knew a safe worthy OC, Thanks
