***The Official Wolfdale 8200/8400/8500 Overclocking Thread ***

Is the TJMax 95 for a E0 E8500 as well? Poxy sensors are stuck on mine, same as my E5200. Bios and Core Temp says 43 at idle while Realtemps says 38. They are all miles out. My 4850 is idling at 20 degrees!! :D Not tried any clocking yet as i have had a nightmare trying to get my 4850 to work. Ended up doing yet another clean install. :( With any luck i will have some results in a couple of days. Not going to kill this one.
 
I got an E0 8400 on Friday, been playing around with it.

This is where I am so far, I did boot into windows with everything at default but a 465 FSB and it all seemed fine but running a little hot. I'm trying to get the best Vcore/Performance at the moment.

Pretty impressive it is happy at this speed with so little juice, is this normal for these CPUs?
 
Well now that i have sorted out my motherboard woes i am currently Orthosing at 4.5Ghz (9x500) with 1.4v. Temps are below 38 degrees loadf although it did breifly hit 42 degrees this morning. Can't tell you how low the temp is as it has stuck sensors but my water pipes are freezing. This is a beauty of a chip. It will do 3.8Ghz at stock volts. To get 4.5Ghz i did'nt even have to increase CPU PLL or FSB Termination voltages. Both are at their minimum settings. If it completes 8 hours i will post a screenie later. It should do as it passed 10 rounds of IBT earlier.

Here you go. 8 Hour Orthos pass.

This is a cracking chip. I have been into windows at 4.7Ghz with 1.435 volts but fails Orthos after 1.5 hours. Needs a bit of tweaking i think but i am not to keen on giving it anymore voltage. Anyway, it also does 4.194Ghz on 1.280v. Did'nt run Orthos but i did run IBT and it passed.

I reckon i can tune the volts down for that so will run Orthos after i have done that. I am really pleased with this cpu. It is so cool running and uses much less voltage for a far higher clock than my E6600 did. It's a fantastic combination with my 4870. Just need Asus to fix the memory dividers again now. :(

Your temps still have loads of headroom, why tune down the voltage and settle for a 4.2ghz clock?

I'm not. :D I just said that i probably could for that clockspeed. People want proof on here which is why i said i would post a screenie of Orthos. Currently i am trying to get 4.7Ghz stable. :D I reckon that if i increased the voltage significantly (which i would'nt) this thing is capable of 5Ghz. I think 4.7 will be the best i will manage, if i can get it stable that is.

Intel officially announced that for 45nm procs any temps below 50 degrees C is basically inaccurate. The DTS is not able to accurately report sub 50 temps. It's also got -5%/+10% error when above 80 degrees. Put that together with Intel's official Tjmax and you're OK. If Tjmax for E8500 is 95, and taking error into account, 85 in realtemp would be the max I'd be willing to accept.

All i know is that my copper water pipes are freezing cold. They don't even get warm. My 4870 idles at 23 degrees and is less than 40 on full load. I am going to rebuild the rig into a new case soon and will be using a Zalman ZM-MFC2 to control fans and monitor temps so will try to get a temp probe as close as possible to the cpu IHS or at least onto the base of the water block. There is no way it will hit 50 degrees let alone 80.

Oh yeah, of course! I am not doubting that your cooling solution will be inadequate! Just be careful and don't get discouraged when reading temps off the 45nm DTS. ;)
