Hey all. I just upgraded to a MSI Z68-GD65 G3 and 2600k! I'm using a CM Hyper 212+ cooler, and would like to get 5.0GHz if possible. I have read several guides but am having trouble going past 4.5GHz, and wanted to post my bios settings to verify.

Also concerning Quick Sync, I enabled the IGP in bios using d-mode. I have 3 screens - 2 connected to discrete card and 1 connected to hdmi on motherboard. Windows 7/64 detected a new video device but when I try to install HD graphics drivers from Intel, the screens goes black and system freezes. I have to boot into safe mode and uninstall the new drivers.

Anyway, here are my BIOS settings for the current OC. Let me know please if you see something wrong. With these settings I am stable for 30+ minutes prime95, and temps around 75 C. Temps seem high to me for these settings. I tried 4.8GHz with 1.4V but prime95 crashes system quickly.

Also I have seen several places that point out to change power limits to 120W or 125W but I don't have that setting in my bios revision apparently. I have read that this is an important setting.

yep that's the one, in normal mode but cpu options still limited. techpowerup screens show V23.1B4 though

Forgot a menu, phase control might make a difference, although I'm not sure what it does yet

What happens if you change power technology to Energy Efficient like in photo? C1E to Enabled....My guess it enables the other options possibly.

so your inquiry would be why the temps are so high or why there are no options for power limit?on my current z68 board if i increase power limit clock stays @5ghz but if set to 150 sometimes clock goes down to 4.5ghz on certain points and no its no speedstep or power saving features.as per temp i think that's normal for cm 212.

Thanks for the link to that thread. I will look at it. I am thinking maybe the newest versions remove the power limit and it's set automatically? Just a guess.

Inquiry is for my new build in general, includes settings to reach 5ghz, temps, power limits, and quick sync. All are related, except maybe quick sync.

I was thinking 212+ was very close in performance to more expensive HSF units. But if I'm hitting 75 C with only 1.375V, what happens at 1.400V or 1.450V or whatever is necessary to do 5.0GHz? Maybe it's time to try liquid.

It was my initial though as soon as I read your post.

Its not a strong enough HSF to stay at 5Ghz 24/7. I wouldn't use it at all to reach that speed.

I'd get one of the H100's or something along those lines, depending on your case.

To me it kinda looks like Ivy Bridge put the final nail in the coffin as far as high end overclocking and air cooling!

To be fair to Ivy Bridge the jury is still out....But rumor is it's guilty as charged :D

If your chip makes the jump to 5ghz then your gonna need better cooling forsure. Going with a water cooling solution would be best. If your gonna plunge then it would be best to do it the DIY way. If you wanna dabble with the all-n-one world then H100 would be what I'd try!

I was thinking of getting a new case. I have a cooler master with one 120 front intake and a single 120 rear exhaust, top mounted psu. I was going to get a NZXT with bottom mounted psu, two 140 top exhaust, and an extra 120 front intake.

Is the H100 active? Does it have a radiator etc?

Check out the h100 at any online retailer. It's a closed watercooling solution for high end cpu's (or high end overclockers).

BTW, I have trouble keeping stable over 4.8 on my 2500k with a hyper 212+ and all of my case fans on high. 4.5 isn't too bad with that cooler on a 2600k with HT enabled.

It's complete all in one solution. Just install and go $99AR at newegg currently free shipping.

Have you looked at the Corsair 500r case? Not sure if it's in your price range or not as not sure which case your thinking about.

If you watch the newegg video for the case it shows the H100 being installed in it. :)

I was looking at the NZXT Source 210 Elite White case. Suppose the H100 could mount in the top where the 140mm fans go?

Looking at the rear view image of the case it looks like it wouldn't fit. If you zoom in on the image you can see the upper fan grill to get an idea of where the fan mounts. It looks like above the MB backplate cutout there is room for 120mm fans. The rad is 27mm thick so most likely it would hit your motherboards upper heatsink or your memory sticks. If that's the case you want you could maybe just mount the rad inside with the fans outside and get some fan grills.

If you wanna use the H100 cooler I suggest looking at the rear images of cases you like and look for what I pointed out above to get an idea.

On another note that case doesn't seem like it fits your build. As in geared more towards a low end build such as i3 or so :)

I got my central a/c fixed today, at 4.5ghz now and 1.365 V (reported by CPU-Z as 1.336 V) I'm reaching 70 C on full load. I tried raising to 1.450 V temporarily, thought that would be plenty for 4.8ghz, but it's crashing with prime95. I don't think temps would be the culprit here, and I wouldn't think 1.45V would be enough to make it crash under load.

Are my other settings okay from my original post? Could it be because of the power limit settings that are missing from my bios revision?

EDIT: Correction, it takes 1.375 V (1.344 V reported) to be stable. Temps at 72. Could any other options from original post be causing it to crash at 1.45V 4.8ghz?

Ihave that M/b I use as my Browser machine . My old gamer used the G80 . Both have the orginal bios . I won't ever change them .

The 2500k is set a 1.35 real is 1.28 The 2600K 1.4 5ghz on water . Your bios is a bit differant than mine but close enough.

Both have C1E state enabled both at C6. 2500k PLL voltage 1.8

2600K Pll voltage 1.85

I don't like your Ram . Wouldn't surprize me if thats not your problem
