Phenom II steppings and max OC 550-940 - Page 126

post #1251 of 2829
Thanks for the pointers, thlnk3r. Some information from the one CPU-Z screenshot I took during all the OC work:

Core Speed 3717.2 MHz
Multiplier x 18.5
Bus Speed 200.9 MHz
HT Link 1808.4 MHz

voltage was +0.075 for that screenshot, case temp 27c.

I haven't documented these OCs that carefully in general because they seemed to be exactly in line with all the previous findings and I haven't yet found the limits of my chip. Also, my stability testing was a bit more haphazard than the standard - I would judge an OC as stable if it could run prime95 and OCCT "as long as I felt like" (30 min or so was all I usually bothered) and let me play GTA IV and perform normal tasks. I'm pretty confident that the 3.6-3.7 ghz overclocks were "truly stable" though, and could have run prime95 indefinitely, based on the fact that temperatures reached stable equilibrium during the first 5 minutes of testing and held steady for the remaining 20+. Anytime I saw CPU temps that didnt seem to be leveling off around the mid 50s, I killed the tests and either lowered voltage or increased ambient cooling.

If this is actually an interesting setup/OC, I can collect some information more comprehensively if people are interested. By the way, I haven't seen many other reports of how linux performs under OC. As I mentioned, it seemed more fault-tolerant than windows at unstable OCs. The linux benchmarks I was using were probably less stressful than prime95 by a large margin, but linux could often boot with settings that resulted in unbootable windows.

i already bought a Cougar 1000w PSU.. will try to burn this one later..
Kairi_zeroblade, I hope the new addition fixes your video card issues. Just a side note, when figuring out the 12volt amperage you simply cannot just add up the all the rails. All you need to do is take the total wattage across the 12volt rails and divide it by 12.

Experimental, I'm sure many other users in this thread would very much like that.

Have you had to make any adjustments to your memory or were most of those settings still left on AUTO?

Good luck

Got my PII 940 tonight... working on it slowly but it's power hungry. Wants 1.45v for 3.60 ghz.

ohh i see so the max wattage on the 12v rail divided by the number of rails??hmmm so by doing so..
720/4=180w across the 12v rails..hmm is it enough??

btw my issues were solved now the only mess i make now is that it just hangs up but it doesn't go off like it used to..

Okay so I quit being lazy and got everything prepped... of course the current graphics solution will be replaced with 2 dressed in black x2's, and I should be doing this tomorrow. Will start off with Dice and will hopefully have some ln2 3d benches by the weekend'ish.

i already emailed them for a new one (hoping) for AM3 support feature and some compatibility issues as well..so far have the same batches you have and using this board can't go beyond 3.977Ghz so far..i tried raising voltages still won't work out clear for me.. any tip bro?? just want to hit 4Ghz..sig rig for more info..

The only tip I can really provide for the phenom II that is the most worthwhile benefit to your overclock is: KEEP IT COLD AS HELL!
