i7 Build - Benchmarking Issues

[CrazigXn]

Built a new i7 machine this weekend (first timer). I am running a few benchmarks and am having issues with two. I read a forum in the CPU board but it mentioned a hotfix which I have. So here is the issue. Any help is appreciated:

PC Mark05 - runs 7 of 11 tests. Completes, but no score, not sure why some tests are failing.

3DMark Vantage - runs 3 of 4 tests, stalls on the 4 test which tests the CPU for the second time. This is the Physix test.

Note: 3D Mark 06 ran fine and scored 14500 however, may not be related

Prime95 - runs along with RTHDribL, hasn't crashed, but I haven't gone more then twenty. But the real issue is the CoreTemp test which shows the CPU maxed at 100% and the temperature of the cores at 95-100 degrees, which is worrisome.

Side Note: 120mm Fans: Any thoughts on the extra two fan placements for making the case cooler?

Last Side note: I played Oblivion for 30 minutes no problem and averaged 60 FPS even outside while battling

System Info:

Intel i7 920
asus p6t deluxe
WD 6400 aaks 640mb
evga gtx260 216 core superclocked
bfg 800 watt power
3 x 1 gb corsair xmsr3 ddr3 1333
cooler master rc 590 case
acer 22"
samsung 22x dvd burner
2 extra 120mm fans (top vents blowing out of the machine)
Saitek Eclipse Keyboard
Vista 64 bit

What cooling solution do you have on your i7? Those temperatures are ridiculously high, and if you're running those temperatures consistently, your processor is dead in a few weeks.

Intel stock heat sink/fan that came with CPU. i removed the wax and replaced with Artic Silver 5. medium load runs at 50 - 55 degrees.

I also download Speed Fan and Speed fan registers 78 - 85 degrees in the cores under Prime95.

CoreTemp still showing 95- 100 degrees.

Are you at 2.66 Ghz or did you OC ??

ALso dod you fit the cooler properly and not use a lot of Thermal paste "Use the rice single drop method" ??

My frineds i7 goes upto low 70C while benching with Prime95 that is why i am about to order a Ultra 120 i think you should do the same in any matter!!

 

[CrazigXn]

2.66, not overclocking. I may have used too much paste recalling. I used the AS5 reommended "line" across the cores, but the line may have been to thick.

does the thermalright ultra 120 have a lga 1366 mount?

Your HSF is not fully/properly installed. You need to reinstall your HSF and work extra diligent in ensuring all four clips are truly fully latched. This is classic overheating sign from a HSF not fully latched down.

I'll reseat the HSF tonight. thanks

Take out the motherboard when you do this. It's annoying, but worth it. This way you can look under the board to see that all four plastic pins are sticking out properly. It should solve your problems. Do not pick up the motherboard by the heatsink when you put it back into the case, and try to avoid touching the heatsink entirely when you put the motherboard back into the case. Also be careful when installing memory sticks because sometimes you can bend the motherboard a little and that can cause the push pins on the heatsink to come loose.

When i did it the first time, the push pins seemed in and sturdy, but I did not turn the push pins afterwards, could this be the issue? I checked the bottom of the Mobo as well and the pins were protruding, but probably not enouhg.

I assume I need to reapply the thermal grease (Artic Silver 5) . What method should I use, the line like I did originally, the rice dot, or the even spread on the heat spreader?

I t will be a process, but I was planning on removing the Mobo to do this , arghhh but what a pain it will be.

You only turn the pins when you want to release them so as to remove the HSF. When latching them you simply press down on them until the click.

Check closely to make sure they are fully latched thru the backside. I grab the heatsink and let the motherboard hang in mid-air while I hold just the heatsink. Then I give it a good side-to-side shake to confirm non of the corners are weakly clasped. If any corner is not really latched you'll feel it right away as that corner of the heatsink lifts while you shake it.

It should feel solid when you twist it. If it is truly latched then you have nothing to fear from maneuvering your mobo inside your case by holding the heatsink directly. It makes a nice handle, but only when the pins the truly fully latched.

Yeah cleanup what was there on the HSF as well as the IHS and then reapply a small line of AS5. Too much AS5 will make your temps increase maybe 5-10C over what they should be, it won't make your temps be 30C higher than they should be (which is your current problem).

so by reseating the intel stock heat sink and using the artic silver 5 grain of rice / spread method, i used a lot of force to get the HSF secure.
i am now running idle between 33-39c degrees.

i launched 5 instances of prime95, one RTHDribl and the internet and the temp rose and leveled for over an hour at 77-82c degrees.

is this where I want to be with an intel stock HSF with the i7 920 (not oc'ing), or is this still too hot and running the risk of burning out the CPU?

 

[Idontcare]

Yep, that sounds right now. Congrats by the way on your i7! I am soooo jealous, have fun with it.

 

[CrazigXn]

cool. will do some more stress testing to be sure, but seems like the machine will be good until I get an aftermarket heatsink/fan.

to all - thanks for all the help and advice.
