I was doing some overclocking on my system last night in order to test the limits. I found some strange results while encoding in Media Encoder and playing back in Premiere. Things actually got worse not better.
When my system was clocked to the defaults video playback was smooth in the preview window and while encoding a segment I checked the log to see how long it took. After the overclocking procedure the video picked up a slight tick or jitter on playback. Media encoder also took about 20 per cent longer to encode the same material? Any ideas? I've noticed people complaining about jitter on playback and being told to overclock to correct the problem. I think some timing issue might be causeing some systems to jerk.
AMD Phenom II X6 1090T Black Edition
Asus M5A88-V (AM3+)
Memory is 16GB GSkill (2-2x4) at 1666Mhz.
Video: EVGA nvidia GTS 450 hacked into the "support" list.
Things run fine at 232x16, 3.712 Ghz and also slower at 3.2Ghz
but when I did a little performance boosting my Passmark Rating sure went up (>8710) but these other things went slower (or ticked) when I thought they should have been going faster.
I notice the problem at 205X20, 4.11 GHz, voltage 1.476.
What have I done wrong?
Are you talking about the PassMark Rating or the CPU Mark? I guess CPU Mark, and not System Mark. The Phenom is just too slow to achieve such a System Mark IMO.
FYI, the best Phenom II X6 1090T comes out at rank # 329, bested only by 328 Intel systems and the bulk of the AMD systems come out between rank # 400 and # 750. See Benchmark Results
I think that by overclocking you are overly stressing your disk I/O system, causing it to skip sectors and introducing latency on reads for playback. I would just reduce your overclock to something that plays back smoothly, since you will not notice any performance degradation with such a CPU.
For sure the frequency of your ram when down whit that O.C. That is probably the reason. Check as well if the latency of the ran was changed.
