E4300 OC, weird jumps with mouse, etc..

[Gadgets]

Hi all,

I'm running an E4300 (with stock cooling) on a Gigabyte GA-965P-DS3 rev. 1 F10 BIOS, with 2 GB Dual-Channel OCZ PC2-6400 Platinum XTC RAM (2 * 1 GB) and have set the BIOS to the following :

Mult : 9.0
Bus : 260
and got a Core speed of 2.34 w/ a rated FSB of 1040.

It was running stable, and was my best yet playing GRAW with no hangs, hiccups, etc...

I left the PC idling for a couple hours, and when I moved the mouse, about every second, the mouse would stop, then jump to where it should be. I hit the reset button, and my BIOS showed a CPU temp of about 53C. I then went right into Windows, and all was fine. OS glitch? High temp? Any suggestions?

I ran bit.exe to stress test, and SpeedFan 4.31 to check my temp, and my CPU went from about 30C to up to 53C during the stress test, and it shows (not sure how accurate), my CPU fan DROP from about 6000 rpm to 3k-4k rpm during the stress test.

Recommendations? Real cooling, better monitor tool, etc.....

Go download Intel TAT (Thermal Analysis Tool) or Core Temp. I'm not familiar with the bit.exe stress test, have you tried Orthos? How much voltage are you giving it? The E4300 shouldn't have a problem getting into the 3Ghz range. In the end you may find it's that darn stock cooler holding you back.

You might also want to check on you voltages from you PSU. Check to see how much the 12v line drops when playing games or running TAT or Orthos.

Odd you should mention the mouse behavior because I experienced similar behavior while I was going through my over-clock iterations. Unfortunately I didn't take notes as to what settings I had when I saw this behavior because I assumed it was a mouse issue at the time. I made my way up to 3.3ghz and ran Orthos test to find out what I COULD do, then I settled in at a very stable, cool-running 3.0ghz overclock for actual use. I haven't had any of those mouse issues arise after several days of heavy use.

I did add a better heat-sink / fan before taking it over 3.0ghz. I chose the Thermalright Ultra-90 partly because of how easy it is to install on a mobo that is in the case - that along with its good reviews. My temps dropped ~ 12c under Orthos load with TAT and Core Temp readings. You might give that a try simply because the new HSF will work much better than the stock HSF. Even if by chance it has no impact on your mouse issue, you'll still being running a good bit cooler and have plenty of room to over-clock to 3.0 or better.

Thanks for the advice all...

I'll d/l those tools, and yes, a better HSF is on the horizon....

I'll post what I find later, and hopefully that will also help others in the future (as long as what I do works!) LOL!!

TAT is weird...

It shows my CPU temp at idle (both CPU cores) at around 60C, while my BIOS shows my CPU temp at 30C.

Any idea?

Just to make sure TAT hasn't gone mad, download core temp and see. It should be within 1 or 2C of TAT. TAT and coretemp read the temperature from a digital sensor inside the CPU. While all other programs to date read the temperature based on the motherboard sensor/probe to detect the CPU temp. The digital sensor is much much more accurate. It is possible that your actually idling at 60C if so time to reset the HSF.

On my E4300 I consistently get much higher readings with TAT than with Core Temp, as in a 15C+ difference. I tend to trust TAT more, because it's from Intel and the 55C it reports after a few hours of Orthos seems like a reasonable value with my Freezer Pro 7. Right now TAT shows 49C and Core Temp 34C.

I can bring it up at 295 FSB on my 4coredual-vsta mobo without any heat issues if I turn up the fans in my Sonata II case, but it's not Orthos stable, currently I'm running at a conservative 266 FSB with no problems at all.

High temp problem solved....

I was running 3 apps the other night, SpeedFan, TAT, CoreTemp, and Orthos to stress test my PC, with the other 3 to compare temps...

In order from low to high, SpeedFan, CoreTemp, and TAT (highest), I ran Orthos, and hit 90C with TAT.. WOW!

Then, after speaking to a buddy of mine, he told me the new Intel HSF with the push button w/ a twist to unlock are hard to push in. My previous Intel CPU had one with a plastic plate underneath the MOBO and the HSF screws into to it.

I removed my HSF, and pushed it hard, and locked it into place, and found that my temps (on average of the 3), was around mid-high 30s idle, and up to 50C running Orthos. Turns out my heatsink wasn't touching my CPU properly.

I'm good to go now, playing several hours of GRAW last night, with all 3 temp apps running, and left it sitting for a while, and no problems at all.

Thx all for your valuable input and recommending all the apps. It has helped a lot.l

I would give it a nice 8-10 hour run in Orthos over night while your sleeping to make sure it isn't throwing errors. My e6600 thows the occasional error after 3-4 hours of orthos at anything above 3.4 on stock volts.

Also, you may have an erroneous service thats running that may be hanging you up too.

Ive also got a mouse that will occasionally jump, but it does it at even the most modest of overclocks. My temps are all in order, and its Orthos stable. Any other ideas what it might be? Dosnt happen all the time, but its weird when it does do it. Most of the time, it will happen at idle CPU load.
