SB - multiplier vs BCLK vs VCore - Page 3

post #21 of 35
'safe' is not what the op is looking for, Im sure he has done his own research on that topic.

Anyways back on topic, maybe this will help maybe not but it does seem that rasing the multi affects how much bclk you use. For example on my chip the max multi is 55 and the max bclk I can use is 100.9, If I drop the multi down to 54 I can raise the bclk to 102. I don't know whether or not im stating the obvious but like I said if you continue rasing the multi then you lose the capability of raising the bclk high.

Hope that helps Xroo and good luck on getting that to 6ghz. Im dying to see a cpu-z showing 6ghz

Munaim1, thanks the dice pot is ready but not looking pretty. Function before looks right? LN2 required a company certificate, so DICE is the only option left. Hopefully it will be enough. If not the MB needs to be replaced. The Rampage board supports 1.85V and more. If I understood it correctly. I need all 4 cores for superpi. I read that 1 core of the 4 is usually stronger. Gotta find which one. I will try tonight at water. To see how far 1.7V takes me. I can continue from there on. 6.0+ or die trying.

I like the way this guy thinks Although I'd be worried about killing a gem like that, not pushing it to the limit is a waste.

DICE is more than cold enough for sandy bridge, I'll have to test a bit & see if there are cold bugs & cold boot bugs, I only dropped my 2500k to -35° or so & it worked well there.
I'll try to give mine a quick freeze this afternoon & see if it is OK down to max DICE temps (-70° or so), your mobo & chip may be different for cold bugs though.
You can use any # of cores for superpi but it is just single threaded so still best to set affinity to the strongest. In the past it could be easier to OC with less cores enabled but I haven't seen any difference in clockspeed with 2 or 4 cores with my 2500k, so don't really need 4 cores but doesn't really matter.

That would be awesome!! I have no idea how it reacts at -0. Regarding killing a gem. Why run 100 meters at 15 sec when you could do it in 10? ;D

I think you misunderstood me. I'd still be pushing it to the limits, but I'd take precautions, such as what you are doing. You plan on making it cold when pushing it, as would I. Other than that, i'd keep feeding her volts. Good luck.

Sorry I missunderstood you i'm just so used to negative feedback so i did not fully Coop. Again, sorry. And yes. the limit is when it doesnt boot anymore. but reaching its limit in Ã* slow and safe way

Yeah what? Should just try another mobo, put 2.0 volts to the chip with a BCLK at 110? Yikes.... It obviously doesn't work that way, see?

DICE should be OK, in windows at my max 55x multi I took it to -75° with no coldbugs & could restart with no issues. After full shut down it cold boot bugged, I loaded a 4.5ghz profile at -65° & had to get to -55° load a 5.5Ghz profile.
Results will vary with motherboards & cpus though.
Maybe just use some alcohol with the dice instead of acetone, should keep it well sub-zero but not as cold as dice can get.
