What about running Prime95 on large FFT's? have you done any proper stress testing?

I'm just experimenting now and I'm at almost 62C on the socket temp just by running 4.4ghz at 1.39V, 4.6ghz seems to need considerably more voltage to be stable (~1.45V) and at that the socket temperature goes through the stratosphere, it just seems to be completely unmanageable.

Okay, I've just tried a fan blowing on the back of the motherboard socket while writing this and the CPU temp goes down 2C straight away, it's not a lot but at least I know it's not directly on the CPU and hence my waterblock is okay, but still if socket temp is linked to throttling how can I pump another 0.06V and 200mhz through the chip without the socket getting hotter?

How are people are getting these amazing temps at high clocks/voltages? are you guys just not testing with Prime95?

edit: I also tried fan blowing on VRM's and temps didn't noticeably change. my core temps are sub-50C under Prime btw for reference.

I don't use Prime as I much prefer OCCT. It's automated so I can set it to stop the test if temps reach a set point. It also records all the temps and voltages in graph form for the duration of the test. This cuts down time spent trying to find out why OCs aren't stable. It's currently running on my 4.6ghz OC and core temps are 49C max (actual is 44C), CPU is 55C max (actual is 55C). That's with 1.464v under load.

If you get no benefit from cooling VRMs (can you monitor their temps in something like I can in the Asus AI Suite?) then you're either cooling them well already, or the heatsink doesn't transfer heat well for some reason.

Also check your VDDA voltage, and CPU/NB voltage. as they are directly linked to CPU temps. My VDDA is 2.7v (quite high AFAIK) and the CPU/NB is 1.35v I think (that's what the board set it to on auto and I believe this is also high. Higher VDDA can help to run lower vcore and CPU/NB helps with higher clocked RAM.

M5A99x with patriot 2133MHz DDR3 10-10-10-27 1T
This is still running as I type this, volts vary 1.392 - 1.404V
Temps on CPU 62 -64C Temps on core 50-52C No throttling on multi.
NB and HT 2530MHz memory 1840MHz
This may be my day to day frequency with cool and quiet enabled. Just gone past 20 mins. tonight, but I have run this many times so far.
EDIT: LLC is Ultra high not extreme as stated
Prime stable on air in my case is not proving easy at frequencies much higher than this. I thought the Phanteks may help but I only have one 120 intake and one 120 exhaust so the case gets a bit warm.

Yes that cpu temp is similar to mine except you're 200mhz higher and my individual cores run a bit cooler, I've not even touched the CPU-NB voltage or speed though it's still at stock 2200mhz (1.187V?), the thing is though if you're getting 64C socket temp now what will it be in the summer? and how are other people managing to run with 1.45V+ without the socket temp skyrocketing into the 70s?

I am running 2.508V and 1.2V respectively. I currently am running only 4.5GHz. for day to day quiet use.

Last nights run was with the benefit of central heating 22C room temp and getting warmer with prime running, but I hear you. :)

I do need more ventilation in my case, it is very restricted as far as fans go.

Hello all and good evening,

Ok so sat down last night and looked at the BIOS and the options available on my board, ASUS M5A97- Pro when it come to overclocking,
There's a few options there I'm not 100% sure about so hoping you guys can help and maybe someone else can get something out of it too.

In the spoiler below are 26 images :eek: of each option that can be tinkered with, I've numbered them for easy reference.

When overclocking is it best to use Manual or Offset when raising the voltages? (Spoiler 17/18)

What settings do peole have for C1E, Core 6 State, HPC and Application Power Management? (Spoiler 22-25)

Last question where have these chips been sat a year?, mine says 2011 on the CPU itself. :confused:

@ Elfmeister. I'm not quoting that lot :p

1# use manual, off-set is just to cumbersome, what that does is up the volts when the CPU is stressed, the problem with that is; if your running an overclock is may need those volts even at idle.

2# C1E, Core 6 State = off, turn all that green junk off if your overclocking, also set to (high performance in windows power options).

"HPC and Application Power Management"

No idea what that is, if its more green stuff, turn it off?

3# The chip was designed and patented in 2011, that why the © 2011. its a copyright stamp.

Well at stock, temps are 7°c Core and 28°c CPU Socket, which I thought was ok, raised the volts to 1.40 and at 4.68Ghz it breached 65° Core within less than a minute on Prime95 Large FFT and the last core had an error.

Needless to say I'm looking at a new cooler :p
 
Coolermaster 212 if I remember correctly, added two Noctua 120mm fans in a pull/ push and have two 120mm Noiseblocker BlackSilent Pro's extracting above and to the rear, my case is an old antec P180 with one 120mm intake.
 
By "65 core" do you mean the cores themselves or the socket temp? if the latter you'll see what I'm moaning about because a new high end cooler will make virtually no difference to the actual socket temp, so even though your cores run cooler you might still get throttling because the socket temp gets too hot.
 
Yeah I meant the Cores, the socket maxed at about 75°.

Ambient air temp of 23/24° and airflow is my issue, since replacing the stock P180 fans with 3 stage power management for the Noiseblockers, I can't extract the air fast enough :(

The new fans do have power management so I may invest in a small fan controller along with a all in one water cooler heatsink to replace the CM212.

Yep, that's too high for cores and the socket. Did it throttle the CPU?

I think this chip is worth getting :)

I'm not sure.

I just did a test on my [email protected], cinebench.
CPU score was 8.07pts.

The Piledriver can beat that BUT, it needs to be clocked higher and requires A LOT of power.

I prefer lower power usage, to achieve similar (even slightly lower) benchmark scores.

Another point is that I am running my CPU at a super stable 4.3Ghz. I'm not sure how stable the Piledriver overclocks are, in order for them to beat an overclocked 2600k.

The only reason why a piledriver CPU would be a worthy buy is if it's price is low.

It seems that when overclocked, the FX8350 is using much less power than a overclocked FX8150 or Phenom II X6.

Yep, some pretty good performance gains over the x6 as well.

£150 dude, i paid over £200 for my x6 way back then, they did come down to £140 just before they stopped selling them to peddle Bulldozer, but they can still be found new today from some retailers for £190 to £260.
