Zippy, why the 21 multiplier? 22 FTW

Yes that has got me thinking if i need more vcore. I wish i knew what to do in bios but it's so much different than the 775 ones i had for years.
Basically set your multiplier to 19 or 21 although some have success with 22. then up your BCLK (kinda like FSB) and hen make sure your RAM speed is set to something stable and something you like. if its 1600 RAM try to stay around that speed while overclocking the CPU. once CPU is stable then you can overclock the RAM. After multiplier, BCLK, and RAM speeds are set boot to windows and see if its stable using prime95. check your temperatures making sure they don't go over about 65 or 70 C using s program like real temp.

And you said you have done some overclocking before so i'm assuming you know you'll need to up voltages for a higher overclock. But from my experience my i5 doesn't require a lot of voltage i got to 4.166 GHz using 1.256 volts vCore.

I didn't do much overclocking before I got my i5 so i'm not sure if there are more or less voltages but its nothing that someone in here can't help you out with. And if all else fails this is OCN so someone can help you.. lol

I would say that unless you just have a crappy i5 batch that you and zippy are needing way to much voltage for 4 Ghz mine reaches 4 ghz on like 1.215v

Also your temps are really high.

Mine are too but i'm planning on watercooling really soon plus I primarily use my Mac. My i5 gets turned on maybe once a month for something random or to play a computer game. If only I could get OSX to run on my i5

I'm sure the auto setting is just overcompensating the voltage. I'll bring it down when i tune.

Yeah mine require a hefty amount in the BIOS for some reason. I turned on LLC but i still have a volt droppage of about .05 volts. But still they are great on not using a lot of voltage!

We're at 4.2Ghz now boys

http://valid.canardpc.com/show_oc.php?id=1536382



Idle's in the high 30's, IBT in the high 70's with an H70

Haven't even started to fine tune

Mem is down clocked at stock timings.

I could do the same thing on the GD80 all day. This chip doesn't do 4.0 without massive 1.4+ vcore.
You probably need more VTT. You can go up to 1.4 VTT safely, and some chips need more than 1.3 as they approach 4GHz. Mine needs about 1.275 at ~4GHz, and 1.325 at ~4.1GHz. Any higher, and I may need as much as 1.35 on the VTT.

Also, as someone else posted, you could always try a 22x multiplier. You may get better luck.

I could only hit 4ghz at 1.28v. I have the QPI at about 1.33 trying to figure out my memory problems.

You guys are lucky you can get to 4ghz so easily. It's taken me many hours to get this far.

EDIT: I tried 22 multiplier, but it didn't stick - I think it's because I didn't enable Turbo though. A lot of people say the odd numbers work better (19/21) which is why I am using 21x.

3.8ghz is a very respectable OC for gaming and 24/7

I plan on stopping there as well when the new i5 sandy bridge comes out.
