Wierd chipset temp problem

[DevilSlayer1298]

My chipset temps were getting up into the low 70's when dual priming. I replaced the chipset cooler with the Evercool VC-RE as recommended. Temperatures are lower, but now I have a new problem. As the chipset temp reaches 62*C my CPU get throttled. CPU temps are is low 40's so its not the CPU throttle. I ran Sisandra's CPU arithmetic benchmark several times. The first run would give me the normal results, but as I run these back to back the score goes down. I tried flashing back to the 7/04/05 Big Tommy BIOS from the official 04/06/06 with the same result.

 

NOTE: This problem only occurs when my system is overclocked to 300 x 9. When I run at stock speeds this doesn't occur. I tried fiddling with the chipset and LDT voltages. They were at +.1v over the lowest, so I tried lowest. Still dual prime stable, but the temps still climb up to 60+.

 

Is this the motherboard throttling the CPU's speed or is this physical problem? And why the hell are my temps so high?! I thought it may have been bad air flow. The front fan is blocked by lots of wiring. I opened the case with no effect on the temp. I applied the proper amount of Arctic Ceramique, same amount as in Angry's video. Made sure to press down on the center to spread it.

 

Rest of my system specs in my sig.

 

How long is DFI's warranty just incase this is in fact a bad board? I have been getting these temps since I bought it.

 

 

EDIT: I just realized, but in speed fan, which one is the chipset set temp. Temp 2 or 3? In the BIOS the temps are listed as CPU first, PWM area second, and chipset third.

To DFI-Street.

 

Even with water cooling you still need cool air moving onto your motherboard. Go into the BIOS, under PC health and set the “NB Fan Fully On…” at 40c. Get some 80mm or 120mm fan pointed on the motherboard, on the PWMIC, and on the MOSFET. Check this out too; Temps Too High?. Hope this helps you.

Ah ha, so temp 2 must be the PWM. In Nvidia NTune, the "System" temp is reading the PWM temp. I was confusing this temp with the chipset temp which is holding at a constant 43-44*C load and idle. The reason PWM is getting hot must be because of my CPU's high voltage (1.622v).

 

This could be one reason for me to upgrade to an Expert since this isn't an issue with it. But unforunately I don't have the money ATM. I can't afford the down time either since finals are coming next week.

Ntune blows. OC using the BIOS and monitor your temps with ITE smartguardian.

I would personal not push CPU Vcore past 1.55v and only to get stability. Voltage=Heat=DEAD_CPU. Even with water cooling. How long have run prime? If you are not prime stable for a min of 8hr. How do you expect to keep your rig up and running? Find your stable point a tweak it from there.

 

Prime your rig for 8hr and post in the Overclocking Database. Good luck and hope to see your post.

Again, its this problem that won't let me get an accurate stability test. Once the PWM temps reach ~63*C the CPU gets throttled and CPU temps and speeds lower. Once I find an extra fan I'll point toward the PWM and see if I'm prime stable. I'm quite sure that I need this voltage to be prime stable, less then this will cause me to error within a minute in prime.

 

From everything I've read over at EOC (and I've been a member there for 2 years now) 1.55v is the generally accepted limit for air cooling and 1.65v for water.

Over Volts will also kill a CPU. I believe that is post somewhere over at EOC.

[DevilSlayer1298]

Theres someone at EOC that has their Opty at 1.7v for quite some time. At my voltage the life of my CPU went from ~8-10 years to like ~4-6 years. I'll probably upgrade in a year and half at the most.

 

And the amount of voltage required to outright kill a CPU is probably around 2v. Not entirely sure.

DevilS, why don't you try MBM5 for your temp and volt readings. Go into software section, top stickey.

Got a fan blowing over the PWM and the temps are in the low 30's. woot woot
