500fsb with a 45nm quad with all 4 RAM slots used? Yes we can!
http://valid.canardpc.com/show_oc.php?id=713216
prime blend running. I know it isn't much yet, but atleast it is showing _some_ stability. It's still running as I'm typing this.

That's only been running 8 minutes, anything can happen.Quote:

If some P5Q Dlx's can, I think this one can too, but it might take some time and maybe some good strong rams to get there, FYI also not all REX mobo's do 650FSB either... always some luck involved...
This is _not_ about 24/7 stability for me. It's about enough stability to run Some benchmarks. Also, I don't think many people are able to boot to Windows at 500fsb, let alone running prime. I stopped prime after 15 minutes without any errors. Working on 9*500 now ;)
9 * 500 with 4 RAM modules installed. Even posting this message from the same machine at the same speed ;) Vcore is prolly way higher than it really needs, just wanted to get some quick validation done. Gonna try prime now. Wish me luck :up:

Small FFT test got a bit toasty. Quickly reached 75c on the hottest core. Blend instantly crashed. Gonna tinker with my settings a bit more now.
try 8 x 500 then mate, these 9650 cpu's prefer to stay sub 70°C
He is doing well, I never managed to prime that long at 500FSB.
Infact most times I cannot even post Bios at 500FSB it is temperamental.
He may have a Rev 3 NB but we cannot see the correct Tab in CPU-Z to see.
Can you please post a Template for that please.
now now lets not be so hasty :DQuote:

I think my board is using the NB rev 2. I'll double check once I have time. Currently playing with loads of setting to gain stability in prime blend :p best so far at 9 * 500 was 2 second :rofl::ROTF:
That screenshot is with just 2 RAM sticks, though ;) using more slots, stresses the NB more, even with the same total size
Yep, it is rev 2. The validation file got corrupted though :p
Hmm makes no difference to me if 1 stick or all 4 (8GB), still temperamental.
Forget 9x Multi for now, use lowest Multi and get FSB maxed and stable.
Why focus on the 6x multiplier? From crashing within 2 seconds of pressing start, to this. I know it isn't a lot, but I'm getting closer. I'm going to continue on pushing this setup tomorrow. It's time for me to catch some sleep now. College tommorow morning. Good luck guys:

Quite an improvement over instantly freezing in my opinion. I can even use the computer now at 4,5ghz for webbrowsing without it crashing at all. I'll continue on tweaking tomorrow. I WILL get it stable, well....hopefully :D
:up:

yes thanks for the already known information..Quote:

Why focus on lowest Multi, you ask.
Well to OC and find MAX FSB you do not leave it on 9 as you will not know if you fail on FSB or overall MHZ as you would be at 4.5GHZ if you got 500FSB.
I think you should concentrate on proving 500FSB is stable before you worry abut anything else.
The above is pointless, showing us Prime for a few minutes at a time, get 500FSB stable at lower Multi then if its 100% raise multi and you only need worry about .PLL and VCore after that.

My 2 cents is use an 8x multiplier and get 4GHz stable in Prime95, LinX, 3DMark and whatever else you choose to throw at it.
We know it's exciting but before you take a step forward take two steps back and consider the easier/quicker way to finding that sweet spot.
Of course as you're in college hence have ample time on your hands you may choose to ignore our recommendation.
what is the highest i could run vNB for 24/7 use?
I threw my Xeon chip back in and am trying to raise the clock from 3.5ghz to see how high it will go for 24/7 use, i've boot at 3.9ghz so i know the chip can go higher. i'm currently working on 3.64ghz (8*455) but so far have vNB at 1.43 and failing Orthos. Load temps are all under 47C. Maybe i need to tune gtl's on it first?
Eeek, what happened to Mr.Pink? Banned you say?
OK, I found a nice Q9650, so I decided to dust off my M2F for some action :)
What's the consensus on the best BIOS for quads now? I'm still on 1901 and I have 1307 on the secondary chip. When you suggest a BIOS please state your reasons.
I'm currently focusing on Large FFT's as its where this board has the most trouble, small FFT's and LinX are easy by comparison. The vcore is obviously much higher than I need for the clock, I'm just testing FSB only. I haven't had much time with it, but this is what I've managed so far.
1 HOUR+ Large FFT / 467 FSB / 1.26 Vtt / PL 8 @ 1.30 vNB / 560 MHz @ 5-5-5-15

Looking at your vcore and overall speed, it's pretty clear that one of these 45nm chips would basically pee all over my q6600, particularly with this board. I'm struggling with 462x8 and on 1.48v. Makes me think how much electricity I could save too!
Think I'll get a Q9650 after my OCZ blades, and will hope to have a nicely tuned, quiet, low voltage rig when I'm done :)
:eek: how is your VTT and vNB so low?? i realize you're only 1hr in but i doubt my board would boot 460 with those voltages. i needed 1.457vNB to get my X3330 (equivalent to Q9400) stable at 3.68ghz (8*460). maybe i need to move to 1901 BIOS from 18xx
I only need 1.27v VTT and NB for 475FSB, its past that's it totally unstable and tempormental.
