Your Haswell-E max stable OC

What CPU do you have?

Still working on max OC on this 5960X both core and cache, memory will arrive this week I hope.

what the hell are you cooling that with :P

Water cooling, very high end :P

360X60 +280x60 radiators with push/pull config on the fans(360 radd has shrouds for the fans and all fans are 2k rpm) and a Hailea water cooler to controll max water temps :D
 
Arr Hailea water cooler haha so you chill the water nice.
 
Nice scores :)

Are you just switching GPU's? GPU's on air/stock cooling?
 
I also swap drives when changing from AMD to Nvidia cards. All GPU's are on water.
 
Dude i wouldnt let your CPU get that hot 90c maybe at the most.

Yep, I only let it run for a few minutes like that and backed off the clocks. I'll probably settle for 4.0/3.37 as it has a fairly decent voltage of 1.13v (for now) and I don't want to sleep in a sauna with a 5820K and R9 290 under full load. The chip can definitely handle more core for sure as the voltage divisions appear to be ~50mV per 125MHz and maybe I'll do 4.12 or 4.25 when my H100 is operational (hopefully tomorrow morning).

Current clocks:

I'm interested to see what temps you get using a H100 i use to run that cooler on my old x79 rig and it did a alright job.


Has any one Overclocked there cache i put mine up to x30 with a 1.25v and seems to have boosted my memory speed.

I am trying 3.37GHz @ 1.25v, 3.5+ seems to be unstable even at 1.3v. Out of curiosity, what's the default cache speed anyway? My board literally says 33x was the default and that screwed me over for a while.

EDIT: decided to try 3.25GHz/1.22v cache to see if my spontaneous reboots stop. 3.37GHz was definitely unstable at this voltage.

3000 MHz is default.
 
Hey guys here's something you should check out for cache overclocking.
 
Yeah, but:



So ASUS users need not worry about it.
As you can see in my screenies a few posts above, 4.5 GHz with 1.3V and here's 4.6 GHz with 1.34V all done on R5E

Think I've posted this before

I'm finally got my hands on some G.Skill 3200 MHz memory that'll arrive in a couple of days, time to ditch this cheap 2133 MHz C15 Crucial memory(cheapest they had in the store).

Hey Mydog just wanted to ask seeing your using the same board as me do you have any problems using Real Temp GT it seem to affect my multiplier.

H100 is operational thanks to a complete mounting kit from The Mad Shot, and temps are about 15c better, so more headroom! Computer is louder though as I swapped two of the four Enermax 900RPM fans on the rad for two 2000RPM Rosewill fans, but I can tolerate unchanging fan noise.

What type of stress testing are you doing to test what your temps are like?

No, I don't have any issues with Real Temp GT 3.70. Going to try the T.I version now. CoreTemp seems to be working fine also.
The only "issue" I have if you can call it that is that it takes a bit long for the CPU to settle at idle after boot, CPU stays at 4.7 GHz for over a minute before it downclocks to 1.2 GHz.
 
I wonder why it changes my multiplier and also the bios reads x35 after i boot into it when it set to x36. EDIT Seems for some reason disable turbo was on in the settings i didn't even think real temp had any settings like that :P.


4.5Ghz on 1.26v

That ^^.

As of now, most anything 2800+ on ram requires the 125 strap/divider to reach the memory speeds. It is what it is (for now). I also agree that voltage is seemingly high as well but if that is what you need, that is what you need. You can confirm this by lowering your memory speed so it wont use the 125 strap/divider and see if that helps.

I'm running my ram on 3000Mhz that's why I'm using a 125 strap do you think my voltages are high? That test wasn't stable running Prime95 im still increasing my voltage till stable.
 
Lost the silicon lottery perhaps? I don't know. With a 5820K I sit at 1.35v and 4.652GHz...and I could probably lower it as it was a 'set it and see if it works (and it did)' voltage.
 
I heard Prime95 shouldn't be used with Haswell-E? I run at this voltage because prime runs stable if i lower it i get a BSOD but have no problem playing games and benchmarking at a lower voltage, My temps never go over 85c so if it need more voltage ill give it to it.
 
Prime with AVX/AVX2 should not be used as it can damage your CPU even at stock speed if you run it more than a few minutes. This info comes from Raja at Asus.
