Haswell Overclocking Guide [With Statistics] - Page 252

post #2511 of 19539
Back on my crappy malay 312. 4.2 core with 4.2 uncore at 1.25v in bios maxing at 1.27 in prime version 28.1. Suppose I'll just be happy until something better comes out. I believe the new 313 chip would have bsod at stock with prime, that's how bad it is.

I was also trying to run 46x cache for a while, but it takes more voltage than you think to make it stable in the long term. VCCIN doesn't need to be that high for 1.19vcore, and LLC is a waste of time. I've tried to save 0.010v or 0.005v by tweaking up all these other settings like LLC, power phase, SA, IO, AO voltages, and Vin, but they don't have any effect. Maybe my chip isn't fussy or maybe the Auto settings are very good on this Asus board.
Had the same issue, turns out I needed more vcore. Take your current core and cache voltage settings and add 0.025v, see if it goes away. If not, then you might need to do a deep dive into your memory timings.
That's a nice chip, I'd be kind to it. For me, 5GHz is bootable at no less than 1.41v. For XTU, my 4.8GHz config needs 1.34v.


I turned SVID back on and set Input Voltage to Auto, did a 3hr run last night. When SVID is enabled, the XTU is able to report wattage. Grabbed a screeny, here's my info. Also, I like how CPU-Z, XTU, and HWMonitor all report different vcore values.
Username: Womper
CPU Model: 4770k
Core Multiplier: 47x (100MHz bclk)
CPU VID: 1.275 adaptive
Vcore: 1.296v
Uncore Multiplier: 45x
Uncore Voltage: 1.275v adaptive
Cooling Solution: Swiftech H220
Stability Test: XTU (2 x 3hr sessions, 1 x 9hr session)
Batch Number: L312B318
Ram Speed: 2133

Hi, I charted that and added verification for 3 hr, because I can't tell how long that has been run, but looks like at least 3hr.

I ran and passed all types of IBT but can't get prime 28.1 to pass.

1.275 vcore @ 4.5ghz with spikes of 90*C during the running...

That is delidded with a Mugen 3.....temps are just NUTS.
post #2514 of 19539
Yea avx2 temps are crazy, i don't use them personally. It's like using furmark as a guide for temperatures on a gtx770 for example, when furmark will pull 255 watts and throttle you to stock while games, benchmarks etc rarely average more than 170 at max oc

What board are you on? What kind of package power readings do you get for 1.25 or 1.275vcore in avx2 prime (28.1) or either avx2 linpack or linx 0.6.5 (same thing)?

That is, if hardwareinfo gives them to you, it seems to work pretty well on giga boards

What programmes in day to day life actually use AVX? I know Grid 2 does as an option but any others? At the moment i've changed from using Prime to XTU and what it's passing is getting ridiculous. I'm now about an hour away from 4.8Ghz@1.243v but i'm fairly certain/expecting when i put it through P95 (27.9) it'll bomb. I only use the rig for gaming & ripping the odd CD so is it worth my time getting AVX stable?

Should have been able to put this under my new loop yesterday but the cpu block arrived with only threads on one port for a fiiting lol, replacement coming this morning so may finally get to water cool this chip after a week of stock issues.

is there a performance boost from 4,5 Ghz to 4.6 GHz in games?

No, bigger slice of placebo pie

So what settings should i run? ....i only do gaming... No bechmarking or other stuff like rendering videos etc.
1. 4.5 GHz @ 1.2v (silent PC)
2. 4.6 GHz @ 1.264v (loud PC)

4.5 for daily. Most people run benches and 24/7@ differing clocks. This cpu would be fast enough to push most gpu set ups in most games @1080p 60hz at stock. There is minimal gain relating to strictly gaming when weighed against the heat, volts and noise required to achieve a couple of hundred more mhz on the clock.
