Winrar question how fast is your?

Sorry my title does not reflect my query please forgive me ;) if you would like to comment on the extraction/encryption speed you have for your cpu please do :)

I recently upgraded to an Intel core 2 Duo and have noticed a difference in the way winrar works. My original cpu was an Amd 4400 X2 clocked to 2600Mhz it enjoyed 60% to 100% full 2 core extraction and encryption my C2d it is not that way inclined it is only grabbing 40% load and a few % on the 2nd core. It still does a fast job but why so little core use. Let me know if you have also experienced this phenomena.

Turn on multithreading in winrar options.

Multi threading is on, didn't have to activate it Winrar must have detected it.

I will re-install again and see if it makes a difference.

LMAO.

Anyway, memory bandwidth plays a more important role in decompression of files.

When I unrar an archive, I see my cpu usage go up to 100% on both cores on my e6600 @ 3.6ghz.
 
smsmasters is right. And the way to more memory bandwidth is through timings. Timings are better than pure clock speed. For example, i was originally at 3-3-3-7-1T at 234Mhz to try and get the computer stable. I've now gone down to 195Mhz (166 divider with a 234 clock) and my timings are 2.5-3-3-5-1T, which is the exact same as my Corsair 1Gb kit IIRC. Now, Windows loads faster + is more stable, my 3DMark score will no doubt have gone up (i still need to test), etc. Currently, my memory bandwidth is 41.84GB/s. This is up from about 40 when had the looser timings with higher clock speed.

Also, decrompressing is faster as well. So timings are a hell of a lot better than clock speed, even if you do have to underclock slightly.

Your ram must be running a temperature, take it to the doctors :eek:

Nope. CBid reports it at 41.84GB/s. I've also got a 1.17Ghz HTT/FSB. Not exactly slow, but not exactly great considering the sweet spot is at 1Ghz. Anyway, i know for a fact that C2D's give much more memory bandwidth than that, part of the reason they're much faster at lower clock speeds (aside from the insane amount of cache they have).

And my memory stays pretty cool, i've got an 80mm fan blowing air from outside the case onto it.
 
Winrar favours lower latency over higher bandwidth. ie Tighter timings over more FSB.
Not sure what b/w that program is measuring but it sure as hell isn't the "normal" measure for memory. DDR2 is pushing ~ 10 Gb/s atm (heavily clocked DDR2 at that), try a test such as everest or sandra and see what the figures are like :)

Good Idea
