bloodrage 24/7 bio oc setting?

[s002wjh]

anyone has a good set of bio setting for this mobo.
i try to hit 4ghz, p09 bio. 24/7 use. i7 920 C0

any advice or setting work for you, let me know.

There are definatly some starting points to get you on your way.

Raise your bclk while on stock/default voltage. When it becomes unstable to the point of having to increase your cpu voltage, for me that point is where I like to run 24/7

C0? Only with HT switched off .. and with some really good air-cooling, or more preferred, liquid cooling. Otherwise its pretty much not possible. You can do that with BCLK 190x21 (forcing mobo to have Turbo always on). Expected voltage on CPU will be around 1.4 - 1.45V if you are lucky.. VTT will need some slight boost, probably at least +200mV, but more likely around +300mV .. which will result in need for high-voltage rams.. cause P09 is very sensitive about VTT to vDIMM ratio.

Actually I would recommand selling C0 and buying D0 or simply better CPU. Cause hitting 24/7 4GHz with C0 is definetly not easy..

yeah i'm running water, so i did get to 4ghz but need like 1.4v.

[Mescalamba]

1.4V thats very ok for C0.. whats your VTT/uncore voltage?

[s002wjh]

i think vtt i rasie about 80mv or so, whats the highest vtt/uncore suppose to be. also whats the max difference between vtt and vcore voltage suppose to be for safety purpose (0.5)v?

[Mescalamba]

Max safe VTT on air is 1.5V .. on water around 1.7V and I guess it all also depends on air-flow inside case.. (VTT PWM is located somewhere in upper part of PWM I think..).

VTT to vCore.. not important.. VTT to vDIMM (ram voltage) is important.. 0.5V is pretty much max.. 0.3 - 0.4V is what I can recommand.

LOL?

I bought my bloodrage GTI and C0 used on overclock.net because the for sale ad said it did 4.0 at 1.24V no HT, with HT it needs 1.3V

Anyways it does 4.0 at 1.216 with the P09 bios, +60 MV on VTT and 1.20 IOH with 1.65 Ram

Rock solid stable no problems.

I am having a bit of a problem reaching 4.3 however, it seems this chip loves VTT and I am using +340MV Vtt but not sure if it safe or not.

Well, if it works for you and its really stable, you are very lucky.. only miracle C0 OC like that..

I've had 5 c0's and theyve all done 4ghz easily Mescalamba. I think people just got so tied up in this D0 furore that they think c0's are bad chips. Quite the contrary - my personal bclk and uncore records are with my 920 c0, and I had that chip at 4.4ghz on straight water. 4.2ghz was a really easy 24/7.

Id be very surprised if theres a single i7 out there no matter what stepping that wont do 4ghz on water with the right psu, mobo and ram.

[Mescalamba]

Well, my own can do 4,4GHz.. its just not 24/7.. unless phase or sumthing similar. I didn´t notice problem with OC.. I noticed problem with keeping it cool enough. I´m quite sure my piece can go higher, just cooling definetly can´t.

D0´s can OC somewhat same but need much less voltage and usually produce less heat..

I´m not amazed by OC, but by those 1.216V needed to keep it at 4GHz. I need like 1.4V or more to keep it at that freq.. (and getting clock interrupt error.. no clue why).

I'm assuming (maybe incorrectly) that anyone with a bloodrage on water wanting to overclock to 4.0 ghz is not overwhelmingly concerned about their CPU working 10 years from now.

That being said, give it what it needs if your comfortable with it.

I have a very nice 920 C0 that I've had in my main rig at 1.4+v for about a year. I had it at 4.2 ghz 24/7 on my blood rage for a while with 1.41v and +300 VTT. It's on a classy now and needs the same voltage.

It's been abused much more heavily in spurts and hit 5.27 ghz under LN2 @ 1.7+v on the bloodrage.

C0's take more voltage, but can overclock fine.

Yeah, longevity is not my concern, I do not keep a system for more than 2 years, except once with a AMD Opteron Denmark 2.6 Dual core.
