Haswell Overclocking Guide [With Statistics] - Page 114

Need some help. I went to grab a new 3770k as a replacement and instead came out with a 4770k and a new mobo, goes without saying I hadn't really read up on Haswell. Anyhow, this and other threads have shown the basics.

So I've set my RAM to 1333Mhz and cache ratio to x35 with volts @ auto.

Now I'm trying to raise multi and it's needing quite a bit; I'm trying x44 with 1.26v at the moment and seems it wants more. But I'm having trouble with all the monitoring tools; Realtemp reports my multi as x43 and CPU-Z (v1.66.1) reports it jumping between x42-x44 which makes no sense. Temps are high 60s - low 70s running Blend.

So besides this weird multi jumping / monitoring problems, are there any other volts I could try? I think I've removed RAM and Cache Ratio as possible problems..

This was my methodology, it seems to work well enough for me.

1. Reset BIOS to optimized defaults.

2. Set CPU multiplier to desired level, say 44x

3. Set cache min multiplier to 35x, max to 39x.

4. vCore to 1.2v, all other settings on auto.

5. Boot Windows (if possible), and run stress test.

6. If it crashes, go back to the BIOS and adjust the voltages and try again.

Adjusting the voltages worked like this for me:

vCore - 1.200v / vRing - auto
vCore - 1.205v / vRing - auto
vCore - 1.210v / vRing - auto

Now, if it crashed three times on three different vCore values I'd reset and try all the vCores again with a bump in vRing voltage.

vCore - 1.200v / vRing - 1.100v
vCore - 1.205v / vRing - 1.100v
vCore - 1.210v / vRing - 1.100v

When, if its still crashing, I'd repeat the process on the next three vCore bumps:

vCore - 1.215v / vRing - auto
vCore - 1.220v / vRing - auto
vCore - 1.225v / vRing - auto

More crashes? Repeat with bumped vRing

vCore - 1.215v / vRing - 1.100v
vCore - 1.220v / vRing - 1.100v
vCore - 1.225v / vRing - 1.100v

That's how it did it. I've got 43x dialed in (seemingly) using this method. I'm confident my voltage levels are as low as possible for this speed. When trying for 44x I noticed that past 1.260v vCore actually made my system less stable, not more. Same with playing with the vRin voltage. Also, on my Asus Z87-Pro I haven't had to adjust any other settings than those mentioned here, everything else is on auto.

It's a tedious process but it helps narrow in on the minimum voltage required.

how come when I tried to do prime95, the temp is like 8-10 degree difference? how do I make it almost even ( 3-5 degree is okay for me)? What do I have to do?

I'm pretty happy, I've got 4.4GHz prime blend stable! Only hitting 70C max normally around 65-67C. I think I've got at least a decent chip. Working on pushing it later. I'm hoping for at least 4.6GHz, but if I can get it to there and I think I can push a little more, I'll be delidding and lapping.

You mean between cores? That's normal.

Here is my official result. I finally got it stable for 8 hours using IETU.

45 multi
1.26 vcore
35 vring
1.2 Ring Voltage
1.8 VCCIN
16g ram at 1600 MHz
Team Xtreem Dark series 4stick 16g kit rated at 1866 xmp. Got it as high as 2400 but have not test for stability
1.65 Ram voltage

Got uncore to 43 at 1.2 and working on memory now.

Batch number is L307B239 Malay chip

I've put your submission into the chart and accepted it as picture verification but next time please try to get them all in one pict.

Grats on overclock!

Chip: 4670k
Core speed: 4.5ghz
CPU VID: 1.9v
Vcore: 1.205 bios/1.212 cpuz with 0.005 offset
Vcache/uncore: 1.205 bios with 0.005 offset
Cooling solution: Custom loop but in need of tweaking for max performance.
8GB RAM @ 2133 (actual ram speed is 2400 so it's actually running slower atm)
