(tbh you uslally never do at this point) The tradeoff iscertainly clockspeed though. Sometimes quite a bit (few hundred MHz)

Im still stupefied at how much higher my cpu runs at the same voltages im stable in prime with. We are talking like 4.8 prime stable and 5.3 hanging out in windows and doing normal stuff like surfing. Same volts mind you. The minute I click start on prime it hardlocks though. I have to reset the pc which is a sign of inadequate voltage.

What're you doing with VRIN and what's your Vcore at? Ring volts? Uncore multi also? I didn't see your other posts if you made any, but maybe you got a ton of headroom and a sick chip if you can boot up multi's like that. It would be amazing if something silly was catching you out and anchoring clockspeeds down

I can't even boot into windows at 4.7 (i think? maybe i can, but DEFINATELY not 4.8) with my 4.6 stable volts, but i've tightened them really sharply over the last 3 months

Currently I'm at 4.8
1.475v
4.6 uncore
1.375 ring
2.2 vrin
.2 sa/ioa/iod

Max temp on the hottest core hits 80 but I think my ram and/or something else is causing instability somewhere. I usually take much less voltage on the core which maxes my temps at about 73-75 but since i moved up to 4 dimms of 1866 (vs 2 1600) its gotten a bit screwy.
Not to mention its the epitome of frustrating having to run prime for hours on end to find out if one change got you stable or not, only to do it again tongue.gif

Ffxiv went live on the 27th and I've yet to play and that is why I built this thing lol. Prime blend is a big reason why. That and my OCD lol. Curse IMC's!

Holy **** that's a lot of voltage!! What cooling you running?

1.475?! Wow.

What're you @...like 300 watts on that thing, lol!
post #2806 of 19539
yes I agree that is alot of voltage I dont see how you remain under the thermal limit unless you are on phase change or LN2 and such PLZ check your CPU for thermal throttling this will occur even on set clocks CPU will downclock to save itself. I have yet to see a haswell run at that voltage without issues with temps even on insane liquid cooling like my setup and after delidding. I have 1/2 inch tubing / 2x swiftech mcp655 pumps / XSPC raystorm / and a V8 copper brass 5 core car radiator attached to my setup with 6x 240mm fans on it / also custom made coolant I make myself that works better than pure distilled water in heat transfer and still protects and lubricates everything and I was still hitting thermal limit even after delidding at less voltage than you. Haswell out of first hand experience heats up like a nuclear reactor as soon as you start messing with voltage especialy 1.4v+ it goes into full meltdown mode so 1.475v i see a bit hard to swallow and staying within the temp range you said 73c-75c doesnt sound right at all.

oh here is proof of my cooling setup pics are a bit older and things have been upgraded a bit since the first 5 are the most recent pics http://valid.canardpc.com/show_oc.php?id=2779392 is a cpuz of that rig in first 5 pics of a stable 5ghz yes stable 90% of time and never gets over 55c on that overkill cooling even when handbrake rendering x264 video http://s1203.photobucket.com/user/rickcooperjr/library/?sort=3&page=1 the cooling system with car radiator I call my torture rack I need to put more recent pics on there which I will soon I didnt care about looks the rigs I put on that particular cooling are my personal rigs I use to torture and dont realy care much about my big rig has a similar setup but alot prettier.


I believe you need to test the setup and show proof of these clocks being sucessfull runs in like prime / IBT / or even better a successfull render of x264 video with handbrake which is in my eyes the best test to run it will put ram and CPU thru the ringer and if there is a weak link it will break it lol.

I need some help for setting up my fan profiles (only CPU Fans) my case Fans are setup for silent settings so CPU fan also quiet as possible (its an air cooler). I must setup the temp for min. Fan speed and max. Fan speed.....smile.gif

You seem to have quite high voltages for Vrin, ring. And why do you use such high uncore frequency ?
Threre is only minor performance gains in certain benchmarks, but you will need to much ring voltage instead. Why not lower this to 40 or 42. It is also more difficult to get high uncore multi stable than 40. Are you sure you need 2.2 Vrin. Did you try lowering vrin and different llc settings ?
For instance I need 1,87 Vrin, 1,14 ring and 1,36 Vcore for 4,8 Ghz with uncore x39. What System do you use ?

Major advantage of Prime95 CustomFFT: you may stress certain voltages.
864K/1344K for VCore
720K for VTT = analog / digital I/O
768K for VCCSA / System Agent
448K for Input Voltage / VCCIN / VRIN (different names for different mobo brands)
512K/576K for Cache/VRing Voltage

need help setting up fan profiles and such good luck with haswell and doing so especially if going to overclock you are trying to make a ferrari perform like a ferrari yet forcing it to sound like a geo metro with performance or enthusiast CPU's come heat which requires more fan speed and better coolers to keep the temps down so good luck if you do get it quiet it will likely get quite hot under load it is the nature of the game if going to play with the big dogs and play with the big boys going to have to comprimise somewhere especially if going air cooling meening silence is likely not going to be an option that will work or keep CPU in safe acceptable temps.


look at it this way with performance comes more heat requiring more cooling same when goes into cars and such also total airflow becomes a factor silent case with low airflow will turn inside if the case / tower into an oven and heat is #1 killer of electronics so GPU / CPU / ram / motherboard / and power supply temps will all go up because of lack of airflow inside tower / case and overtime it will get worse due to dust and such.

Ask and u shall receive I suppose (screenshots). Though I've never been asked to prove I have a slightly above average overclock at high voltage. Like I said, I think my ram or something else is causing instability. I can run all stress tests at lower voltages but prime blend is the bane of my existence. Until I get that to pass Atleast 8 hours, ill never get it outta my head.

I am most definately not on phase, I wish. And use your noodle, if I was on that - let alone dice or LN my temps would be more like -80 tongue.gif

I'm running ek blocks on my 480s (they hit 41 under load) and a supremacy on my cpu. (Its delid and ran naked) I use the same pump as everyone (mcp655)
And it's all being cooled with 2 xspc Rx series rads. A 360 and a 240.

Fan wise I have ungentle typhoon ap31s (150cfm)

Ill get pics up when I get home tongue.gif
