This C batch seems to be pretty good so far. Sensors are off a bit but that's nothing new. Will keep trying for 4.5ghz stable.

Thanks. Yeah me too.

@OC Nub,
how much voltage do you set on the nb?

I am using 1.44v MCH/NB. Started at 1.46v but trying to get it lower. The 250a/4:5 divider has been a real PITA to get stable.

**Fritz_the_germ** · 07-20-2009, 12:31 PM

Thank you for the info.

My goal is a fsb of 500 Mhz by using the 333/800 strap (=4:5 divider) to get my G.Skills at least on default (=600 MHz=DDR 1,200 MHz).
Before this DFI I had a ASUS board with a X48 chipset. A X 48 isn´t really made for quads. For a fsb of >460 MHz using a quad you had to fire more than 1.5v to the nb

. That´s to much English for a 24/7 setting.
The P45 chipset doesn´t need so much vnb.
However about 1.45v should be right. I will try in the next days.

Nice chip OC Nub, especially coming out of these newer batches.

**OC Nub** · 07-20-2009, 02:45 PM

Thanks Hoss. Was shocked when I saw the vid.

**LennyRhys** · 07-20-2009, 11:54 PM

Yeah OC Nub the chip is very nice, much better than my C chip.

What have been your highest load temps so far, and is this air cooled or H20?

With my silent red wing fans push/pull, max temp has been 69C at 1.368v.

**Fritz_the_germ** · 07-21-2009, 01:12 AM

@OC Nub,
you told us in you last post that you set ~1.44v to the nb to get a fsb of 480 MHz stable.
How hot gets your nb under load?
Do you cool the nb by air or H²0?

**OC Nub** · 07-21-2009, 03:36 AM

This board doesn't have a sensor for the NB. I use a 120mm fan to help cool it. only reason it needs 1.44v MCH because of the 4:5 divider, at 1:1 it takes 1.36v MCH for 500fsb.

Theres a program called MCHTemp that will show you nb temp once it gets about 50c and above. Its in russian and it doesnt have signed drivers so you have to F8 boot to use it. It looks like this,

**Fritz_the_germ** · 07-21-2009, 09:08 AM

I am using an infrared thermometer (TFA Scan Temp 380) for places where I don´t have a sensor.

Thanks Lenny, Highest I have seen at these clocks after 8hrs prime was 64c on 2 cores. My sensors are bugged on 2 cores so IDK how acurate they really are. It is on water cooling. This is my third 8 hour run at this oc, I had changed a couple settings last night and it became unstable so I tested again.

Hoss: Thanks, I will try that MCH program.

**LennyRhys** · 07-21-2009, 02:41 PM

These C Q9650s seem to be good chips, some extremely nice with low VIDs, but not for air cooling if ya know what I mean

5010 just got himself a "golden" L847C - it has 1.15 VID, does 4GHz stable on 1.17 and 4.125ghz on 1.19v

**scharnhorst** · 07-21-2009, 10:56 PM

Need one

**OC Nub** · 07-22-2009, 01:22 PM

Working on this now, think it will probably need another bump in vcore but finally 6 months and 3 q9650's later I am close to my goal of 4.5ghz.

**Machinus** · 07-22-2009, 01:56 PM

What RAM are you guys all using with this processor?

**Kai Robinson** · 07-22-2009, 03:03 PM

I'm using 4x 2gb Corsair PC8500 C5's @ 1:1

**OC Nub** · 07-22-2009, 03:21 PM

Machinus: I am using 2x2gb GSkill pc2 8500 at the moment.

Still working on 4.4ghz, looking better.

**OC Nub** · 07-22-2009, 05:19 PM

4hours (or close enough) Prime blend 4.4ghz. I took my OCZ LV1.8v ram out and put my GSkill f2-8500CL5D 2.1v kit in. Forgot to set ram voltage back to 2.1v, started Prime up and has been running at this voltage stable. I am running 1:1 so maybe 2.1v is not needed?
Thank you Sergio for your help on MSN, you have been a huge help to me in learning this board and getting settings right to become stable.

**OC Nub** · 07-23-2009, 03:27 AM

Passed blend overnight.

Well as i cant prime this beast not even on water at this vcore i decided to left it overnite folding...the giga loves this 4500 /1200

Cheers

Sergio

**ViViD** · 07-23-2009, 11:56 AM

Wow Nice Vcore U Guys
I'm Try To Stable With 1.42Volt On 500 FSB
Finnaly Kill DFI

And Kill Myself Too

Thanks Sergio. Great job with your 4500mhz. Its hard to Prime a low VID chip at over 1.4v even with water as you know. I think I have reached my limits also with temps in Prime.

Vivid, I hope you will try the Gigabyte UD3P or UD3R board when you are done with your DFI. I believe you will be able to do much better and possibly with less voltage using the Giga board.
