SB is easy,
raise multiple, add vcore.
MSI P67 gd55 2500K

Priming some at 5ghz 1.432v

So did you disable turbo?

Slightly confused about this turbo thing.
 
Anyone ocing their SB, can you please run LinX and post your screenies so I can compare the GFLOPS? I saw one SB at 5.2Ghz with 4c8t, but LinX shows it barely break 60 GFLOPS. My i7920 with only 4c at 4.2Ghz shows 61.5 GFLOPS. Weird.

I feel like a lot of people on here (and other places as well) overclock more for bragging rights than for any sort of practicality. Frankly I see NO reason at all to risk destroying a processor just to get another 200-300mhz out of an already insanely fast processor.

I won't be going over 1.37 with mine when I get it.

going faster isn't practical? My old Q6600 was cranked about 1ghz up for 3 years, I don't think there is a risk in damage unless you do an extreme OC.
 
He means it's not worth it to crank up the voltage past what is considered safe to get an extra 5% of clock speed or something when what you have is already beyond adequate for now. It's fine in moderation, like almost everything.
 
Exactly if you can get to 5Ghz on 1.35V by all means do it, but dont crank it up to 1.5V just to see if you can hit 5Ghz
 
Well, these 5 ghz overclocks are definitely highly over rated. I have the AsRock Extreme 4 (highly rated by Anand) and I couldn;t even get it to post at 4.5, but seems stable at 4.4 ! Loads temps under 70

1.35 vcore....

Do you even need the heater on in the winter with all all those PCs running?

That's what Gillbot was talking about, lol.

Mid to high 50s load with a 2500K @ 4.2 and 1.272v. Hyper 212 Plus. My temps are on the high side though because I didn't apply the TIM optimally the first time (direct contact coolers have a different procedure than other heatsinks). Once I redo the TIM, it should be a bit better still.

Whoa whoa, back the train up there... direct contact heatsinks require a different TIM application? Where can I find the proper instructions? I didn't know they were different...

This may explain why my e8400 gets up into the upper 60's/low 70's with my CM Hyper TX2 as it's a direct heat pipe and I did not change the way I apply the TIM. My A70 thats waiting for the 2500k to arrive tomorrow is also a direct contact so I'm glad I saw this.

Newest bios mark?

Have you tried upping the vcore more? My extreme 4 is waiting on my front porch and the 2500k arrives tomorrow. I'm taking Friday off to build and bench all day 🙂

I tried 1.36, but I won't go over that from what I have read. It won't even get the XP splash screen at 4.5 !

I might even be able to lower the vcore, but tired today. Might try updating the bios later.

My IV's shipped bios was terrible. Upgrading to the newest beta cured it.
 
Basically 1.35 is the highest recommended if you want no effect on the lifespan of the chip for sure, but 1.38 still probably won't do anything drastic. Of course depending on your cooling and the chip you get, you may be able to go to 1.4 or even slightly higher without affecting the lifespan much, but do you want to find out in a year that you didn't have some golden chip? I know I'm sticking to 1.35 when I do my build, unless 1.38 gives a decent bit of overhead. But 1.38 will be the absolute max for me.

ok, I'll aim for 1.35 when I get to building. I never did bump the vcore on my e8400, wonder if that may have held me back in my OC...
 
long thread, id like to knpw if there is any noticeable performance decrease if any when running single channel, im considering to get one 4gb stick and get anpther in the future for my 2500k+p8p67
