Is this normal

Hey got an H50 installed but when the cpu load is on 90+ the temp increase to about 80+ and I dont think this is normal. Here is a test i did

I aslo did a test with prime95 it goes all the way up to 100c. Here are some graphs.

I was thinking if I should lower the vcore currently at 1.344 down which would also give better temp at load.
 
It is most definitely -not- normal. Is the fan plugged into the CPU_FAN header ? Is it spinning ? Is the pump working ? Have you mounted everything properly ?

Those temps are -way- too high, something's wrong. Before overclocking, make sure its working properly on stock volts.

1.36v for 4GHZ doesn't seem right:confused:

Could also explain the high temps.

True, but note that his idles are around 50 and as soon as CPU loads up temps jump to 90 in like 10 sec, no gradual progression, nothing. That's something actually wrong with the setup, even under those volts temps shouldn't rise that fast. It sounds as though the pump isn't even working. But heck, yeah the volts are a bit much.

Ok well the issue was with the fan it self not the h50, it seemed as the old fan was taking in air instead of out so I changed it with a different one. Here are the new readings.

What voltage is recommanded?
 
Mate, I'm telling you, your going way overboard with the volts for this chip, its not a phenom lol. People have maintained a stable 4.0 Ghz clock with as little as 1.216 ! Go have a look at the H50 thread, you should be aiming at mid 30's idle and 60's at full load. More than 70 is pushing it and should not be acceptable.

Also, it would be helpful to see a test using stock clocks and volts.


I feel you may have jumped the gun too soon, start with stock everything and work your way up, only increase voltages when the system becomes unstable ! Even then, with small increments.

Well It seems as though i did jump the gun. I am currenlty at 1.2625 volts at 39c idle 70c max at 100% load

I'm certain you can go lower than that unless you were really unlucky with the chip. Try it at 1.230.

Need I remind you that its not the extra volts that make the CPU faster, its the clocks and the less juice you need to sustain them, the better.

70+ is fine. Hell, I run my 920 @ 1.35v for 4ghz. Could probably go lower but I cba tbh.

Fair enough, but the guy just went from running 4ghz at 1.360 to 1.262 effortlessly, why not see with how much he can get away with.

Then again, your probably right, not everyone is as neurotic about shaving off those few degrees as I am lol. :rolleyes:

Will try. I also currently have the dram bus voltage at 1.64.

Can't comment on that without knowing your other components, but do try to be conservative when it comes to volts, upping them only when you need to. Also note that some motherboards like to overvolt a bit on top of your config, keep an eye out for that as well.

Finally, manufacturers like to give stuff more volts than it really needs just to be on the the safe side in terms of stability, meaning you can more often than not overlcock things nicely with stock volts and sometimes even less than that !

Vcore could probably be lowered if you go for 21x191 instead of 20x200

But man, 20x200 looks so much nicer. I know my 20x200 has a similar Vcore to keep it stable, I should test if a 21x191 can make it a lot lower and cooler.
 
Well its seems the more i decrease the voltage the more system crashs i get. I am currently at 2.8 which seems to be ok so far.

here is my set up

Corsair 6GB (3x2GB) DDR3 1600
Antec Nine Hundred Two Case
Asus P6T SE X58 MoBo
Intel Corei7 920 D0 Step SLBEJ
CORSAIR 750W 750HXUK MODULAR
CORSAIR H50 CWCH50-1 INTEL/AMD
NZXT SENTRY TOUCH LCD METER
1GB XFX HD5770 DDR5 PCI-E

Got a final voltage of 1.28 which is stable for the OC. The temp readings are 40c at idle 80c max on 100% load.

Well, thats certainly more reasonable, still pretty hot though. Is the temp progression curve still as steep as before ? I'm curious, mind posing another test ?
