To me underclocking would imply running a processor slower than the manufacture's stock speed. Anything over stock speed is overclocking, at least it in my mindset. Granted the chip could possibly go another .5 Ghz though.

I'm happy with my 4.5 Ghz overclock. Like you I may go for a higher overclock just for the fun of it someday.

Wait, that's what I was going to say regarding the "underclocking" comment.

You are still overclocking the CPU frequency, but using a "negative offset" is just minimizing the CPU "jump" in voltage that will occur due to the CPU being programmed to instill the voltage. i.e. CPU VID.

There are people who "under-volt" their CPU at stock settings, to run at an even lower VCORE , but that definition wouldn't make sense either, since, using a negative offset with, say, a 4.3ghz overclock, would still have the CPU running at a higher-than-AUTO-vcore i.e. 1.250 - 1.300

Anyway, does anyone know if using a severe negative offset, besides not being able to boot into windows - --- can it damage the CPU??

It seems to be the generally conscensus that overvolting the CPU will fry it- but not too much logic regarding using a low-low voltage, despite, as previously stated, not being able to boot into windows.

When I blue screened using a fixed mode while overclocking, they tended to be c0x000000124 errors (vcore).

When I was testing using a negative offset to reduce my tempertures for my overclock, I recieved the c0x000009c blue screens that stated something such as 'MACHINE OPERATION" etc...

I have 4.3ghz running at the -0.090 offset right now, and I hit about 1.240v under 100% load, and that results in 60C's temperature on all 4 cores, though, 1 or 2 cores spike at 70C or 67C at some points.

So I have no idea how you guys keep cool at 1.3v-1.4vcore while overclocking. I mean, I have 2 Silverstone AP181 intake fans which are highly -acclaimed and desgined intake fans, and i have a scythe KAZE 2600rpm as my exhaust fan which is a BEAST, and I have the Noctua NH-D14 , which we all know to be one of the best smile.gif

I think Kenney wrote the +0.005 offset with overclocking as high as you can go before stopping. From what I've read here you have to have a positive VCore if you go over 4.7 or something to that effect.
I've seen several members here content with stopping at 4.3 or 4.5 ghz and not overclocking any futher.

I haven't heard that about having to use a postive vcore offset for surpassing 4.7ghz.

I've seen on the hard forums, that the rep from ASUS posted about enabling PLL voltage to get 4.8ghz stable ++

But, when using the 47 multiplier in BIOS, and offset positive mode , of say, 0.005+, even then, the motherboard will default the voltage under load to be HIGH!!

as can be witnessed when using "auto" mode for voltage and running a multplier of your choice - watch and see how the it is by Default CRANKED up excessively HIGH.

That's why I didn't understand why so many people seem to be running positive offsets - when the logical brain dictates that a negative offset be used, not for everyone of course, but atleast more guides should mention it.

I question whether people who overclocked using a +0.005 offset realize that they could potentially drop the offset and reduce their tempertures at the same Frequency, or even overclock to a higher frequency

Yeah, it may not take that much work to OC these to 4.5, but geez, I don't turn down free meals, either. biggrin.gif

Using OCCT, Real Temp, or CPUID HW Monitor, using prime I'm getting temps in the mid to high 50s, with spikes in the low 60s. I am using the CM 212 Hyper Plus, and I used Arctic Silver 5 for my thermal paste. I'll post a picture to validate these clalims. My fan speed is just under full speed. My case has front and rear fans, nothing extraordinary. My vcore under load runs around 1.28 - 1.31, which is better than it was. I take no credit for these set tings, stealing them with no shame from Lucky 23, copying his settings verbatim, and it turns out they worked for me as well. So my hat is off to Luck. He is one solid guy here, puts in a lot of time and energy and support and does not get nasty like some folks around here. wink.gif

So i've been playing around with my overclocks and have managed to get the following results while being stable.

4.4ghz @ 1.28v load (Offset +0.005, LLC Level 4) 62 deg load temps

4.6ghz @ 1.34v load (Offset +0.005, LLC Level 2) 67 deg load temps

4.7ghz @ 1.39v load (Offset +0.010, LLC Level 1) 71 deg load temps

4.8ghz @ 1.42v load (Turbo 50 auto BIOS O.C) 80 deg load temps


Is the extra voltage/heat worth it for such a small gain in speed? Any other things I can do to bring the voltas/temps down further and keep the same speeds?

Right!
Maybe Kenney was thinking about us using a negative offset as underclocking.

Another thought is while we are using a negative offset and running prime for hours to check stability we should also let the computer sit idle for a few hours to see if stable. I did have windows freeze once while idle so I bumped up the VCore a notch and it hasn't froze since.

It seems I saw it mentioned somewhere but I could be wrong. I do know in my case as I go higher with the multi, I also have to increase VCore as well.

Maybe the CPU's are more energy efficient now. Who knows. thumb.gif

are my vcore ok or is it to low?
338
1344 FFT with 90% of ram run in 15mins.

bios :
cor voltage - offset - .0035v
pll - 1.709v
vtt - set to auto
llc set to level 2

bios shows that my vcore are 1.306 switcing to 1.312v

cpu shows (under load) mostly 1.288 & 1.280v
but sometimes kick to 1.296v and goes down to 1.272v
what LLC settings best fits for me?
Thanks you!

btw, I also ran 1792FFT for 15mins and also passed
338
do I to somethng or should go P95 blend? and what settings?

Hope everyone has a n ice holiday weekend. It's beautiful and in the low 60s here in northern Utah, clear and with the mountains still sparkling with snow.

It looks like you are on the right track but I'm having difficulty looking at your screen shots of Real Temp and CPU-Z. It looks like you are running at 4.5 Ghz as best as I can tell.

Post only your Real Temp and CPU-Z so the size will be larger and we can read it better.

Same here! It's a nice warm 75F down here.
