Maximum overclock @ -50C stable

I have a dual stage cooler hooked up to one of these rigs i got and i am trying to reach the maximum overclock. The thermostat is set to -50C stable. So far I have been able to reach 4.73ghz stable at 430FSB x 11 multiplier @ 1.56V. I couldn't take pics of that but I did take pics of 4.4ghz at 400x11. Whats the maximum i can reach. I am having troubles reaching 5ghz and above even though the temperatures remain at -50C at 4.73ghz. I just need to get the right numbers in. What do you think 450x11 @ 1.60V?

I agree its really ancient. But it keeps hitting my head that i never overclocked this one CPU to its maximum and I have always had troubles with this CPU.

Hmm, which temprature remains -50c? cpu/evap? Anyway to gain 5Ghz you probably need like 1.7v

I get 4.6ghz and 4.8ghz very unstable. Shows me a red for anything above 1.6V. I have already enabled the jumper to 2.1V max why would it not let me go higher?
It does not let me get into windows. The temperatures were still stable below 0C on CPU and -50C on the head.

If your just trying to bench dont worry about the red...just dont leave it at 1.7 for hours...

Why not.. it remains below 0C. I leave my 2 stage on for months and running at 50-100% overclock with different rigs. I am getting a lot of bluescreens now. Running at 4.4ghz and anytime i play a bluray or HD movie it bluescreens with PFN list corrupt or other stupid errors. I think its the RAM because 8GB 1600mhz is unstable on this mobo even at 800mhz. Really fked up. I never gonna do LGA775 again its a total fail. Damn nerds cant make proper stuff.
I had enough with this CPU and Mobo. I am gonna put it in my trash compressor and blow it up with a shotgun then run it over with my car and send the vid to intel and asus.

Why not? Because it will eventually cause voltage migration and permanently damage your chip.

I wrote a very long thread on this a few years ago with the calculations to demonstrate why this happens.

Welcome to 2008. Enthusiast boards do not cooperate well with all the memory slots populated with high density DIMMs. Hell, even the server platforms downclock the memory when you fully populate the memory subsystem. That all being said 4.4GHz on a single-stage for a 65nm quad is pretty good if I recall correctly. My Q6600 G0 required around -90 Celsius for 4.7-4.8GHz, so you might be expecting too much out of that chip. Yorkfield(Q9xxx) will do you much better if you want more frequency, that added 500MHz of headroom to most chips. You can pick up a QX9650 for dirt cheap now and they do 5GHz on a good single-stage and 4.5GHz on air.

bit OT, but personally i haven't see any QX9650 running 5Ghz+ stable=(successfully 30min IntelBurnTest) with 4 cores + not totally insane voltage by cooled single-stage

Who runs IntelBurnTest at 5GHz? My QX9650 would run 5-5.1GHz on an SC18CLX single-stage just fine for everything I used it for ranging from gaming to some quick 3D06 testing. You have to think within reason when pushing high clocks

When on SS at 1.41 vcore mine runs happily at 5ghz but it also does 5.5ghz on a cascade so maybe its just a very nice chip....

Well atleast i use IBT just to test is cpu stable or not. If it not crash IBT, it won't crash 3dmark either ..Anyway point just tha,t if somepoint i need to use program X what loads cpu so much it could crash...eg 3d-stable not enough for daily-use.

Yes i have runned my QX9650 with 5Ghz with IBT stable with 1.6v..altough this required minicascade :P. I don't say that is not possible to get IBT ok with 5Ghz+SS+decent voltage....just never seen "proof" of that :P
