Windows 7: Post Your Overclock!

That sounds like something else other than prime95, or that prime95 is crashing the system, which is odd. Have you checked for an updated version? - Prime95 (64bit) - 25.11 Download - EXTREME Overclocking. this the 64-bit version. That's the one I'm using without issue.

Sygnus, I will give that one a shot. The interesting thing is that this freeze has occurred before as well (while NOT running Prime95), but I have never managed to figure out the cause.

If you've been having freezes prior to using prime95 then I can pretty much guarantee prime95 will fail now if run. In this instance it will confirm what you already suspect – the system isn’t stable. I would be trying to figure out what’s going on there instead of worrying about prime95.

Memtest your memory.

My two cents

Neither. The entire computer freezes, with no power to the keyboard and mouse. If there was a sound playing when it froze, it stay playing that sample of sound on the speakers.

Hi Lordbob - Are you saying that when the Computer freezes the Keyboard and Mouse loose power too ??? Are they connected via USB ?

Yup.

I will give MemTest86 a try tonight.

Hi Dave 76 - Yes, it's a nice rig - it runs very cool (though it is water cooled). The entire rear panel area feels almost cold to the touch and the main fan is almost off most of the time. Really strange to have a rig run so very quiet (its a nice change). Under full load, the main fan will speed up though. I haven't yet tested it with a program like Prime95. My last rig was an Intel quad core and it was water cooled too but it needed multiple fans (which were always on), made a ton of noise, got really hot on the real panel (even with no load), and only ran at 3.3 Ghz.

The core speed idle question ? - well the CPU CORE NON TURBO RATIO is still at 25 which maybe explains why CORE TEMP reads the multiplier as being low under "no load".

The Intel Speed step is enabled as well as the Hyper threading and the Turbo Mode is ON.
In the 980x the turbo mode is independent of the number of active cores as long as the TDP isn't reached.

Which Intel OC'ing App are you referring to ???

The rig came "Overclocked to 3.73 Ghz" by Alienware - I just increased the Core Turbo Ratios to 30. I haven't changed the voltages yet. I've been monitoring temperatures with CPUID HW Monitor and CORE TEMP and have yet to see any temp go over 55 C, even under full load for a while.

Just my guess, but I guess its the Turbo Boost which is getting the rig up to 4 Ghz. But what puzzles me is why CPU-Z always shows me at 4 Ghz (loaded or not) whereas Core Temp only shows a multiplier increase when I apply a heavy load. Can CPU-Z read my core multipliers ????? Or is my Core Speed always at 4 Ghz ????

It would be nice to run faster but I'm pretty happy with the speed of this now - I don't want to take any foolish chances for that last "bump". It seems run run cool and is 100% stable.
What do you mean "Pretty low core voltage for a 980x" ??? What core voltage are people usually applying to a 980x ???

Your Alienware should come with Intel's Extreme Tuning Utility.
Dell's Alienware Club forum, IXTU

Quote:
Dell recommends only using the AutoTune feature and that you choose the 1st option, "Stay within the manufacturer's limits".

If you decide to use the Manual Tune feature, users should be knowledgeable about advanced PC hardware settings. Improper settings can permanently damage the PC.

Sounds like that's what you want, Manual Tune feature, the disclaimer sounds like it lets you do more than the BIOS will.

Intel’s new Extreme Tuning Utility - Here is a quick review with some screen shots.

Read about this a few days ago, most were saying it's the same as most mobo OC'ing utilities, ok for a small OC but not good for higher OCs.

If it lets you have a few things to play with it might be helpful, or looks like it might be a good monitor/info utility.

EIST is Speed Step, it's likely CoreTemp and CPUZ may not be programed for your CPU.

The CPUZ snip showed a multiplier of 30 at 4GHz and 1.056v, that's really good low voltage, haven't seen any X980 OC'ed specs so was wondering if that is normal.
The IXTU app might be good for getting the true system readings under various loads.

Hi Dave, CPU-Z and Core temp does work with those chips. As for the voltage, yeah 1.056 is very good. I asked about it earlier, but didn't get much info since he said he has limited access to the BIOS.

As for the 30 multiplier, since the chip is unlocked, 30 is very possible, and would be normal on that chip. Not to mention that achieving a 4gig OC on it really isn't all that hard. I can do 4+ gigs with my locked i7-950, so an unlocked i7-980x doing it is nothing.

Having that low CPU voltage definitely keeps temps down and I'm betting he could push that chip higher, 4.3 or more? But with limited BIOS options I wouldn't push too much.

So I ran MemTest86+ for a few hours (only 2 passes) and it came back clean.
To be honest, I think the motherboard might be a bit borked, but I don't know how to tell.

The thing is that it normally works just fine.

Does the board have any diagnostic lights?

Also, you can check your BIOS to see if it keeps a record of issues the MB is having. Most motherboards usually keep such a record in the BIOS; you might check the maintenance section of the BIOS, should be something like a log.
