Can you see my SS with Orthos ??? that's CPU stability my friend

The "In-place large FFTs" test uses relatively large FFTs which cannot fit into the CPU cache so this test accesses main memory a lot. It only accesses a relatively small amount of main memory because it runs the FFTs in-place so it accesses the same RAM over and over.

The vcore for 4.2 is rather high,should go 4.4 like that on this batch and the vcore.

hmm maybe different mobo... will try again with Mars

Nice results TS.
But it seems like the vcore is a lil bit on the high side right?

Nice E8400 and looks like most people should be happy doing 4.2Ghz stable for daily run.

Btw, I see E8500 on pricelists already

1.42V aint that high i think
its still acceptable & with decent(no need those really hi-performance) HSf, temp should be just fine

ps: wolfie really make me itchy..

Yes, 1.42V is decent and is what reported by many other users as well (around that voltage range)
We should go by facts, not the assumption of Super PI completion = stability right?

source -> line -> component -> short line -> termination

the "lines" in this case are signal traces. works a lot like a SCSI bus. high speed switching operations can cause reflections on the line (in essence, this is resonant noise caused from high-speed switching on the lines as the memory controller gates on and off to place data on the bus, nothing more than rising and falling voltages). clearly enough, the faster the signal switches (higher frequency memory) the more noise.

termination resistors, used in passive termination environments, are exactly matched to the target frequency for operation based largely on trace length, ESR (equivalent series resistance) and the over capactive/inductive nature of the circuit, as well as some other things well out of the scope of this post. problem is that this is often matched for a specific frequency...which as we know is not so cool for overclockers. enter the active termination system. this actually uses a voltage bias to set final line resistance value so that the user can tune for better operation when overclocking.

this method of tuning is largely trial and error as you have no way of know the specification of the circuit or have any idea of the calculations need to find the "perfect" value. so anway, the answer is, strangely enough, whatever works best.

hope this helps.
