What is better for chess and overclocking

[gigabyte137]

Just curious with an E6600, 400*8 = 3200
or 355*9 = 3195

Both with the same memory freq as well.
Does raising fsb increase chess output? Or is it just the total freq that matters with chess? Thanks in advance...

They are so close , I would go with which ever one is more stable. If they are both stable equally - 400*8 has slight edge ( is my guess) but the difference may not even be measurable or verifiable due to latency.

If you are not overclocking the memory, it makes no difference. Go with the stabile setting but sometimes although same speed, bios changes memory timings with higher fsb. It is a good idea to check both settings with cpu-z and see that 400fsb is not forcing slower timings.

Well I can do either 1066 at 5-5-5-15 or 920 at 4-4-4-12.
which of that is better for chess?

Hard to really tell ... some people think that lower latency gives better overall performance ... but most think that going with a higher FSB with a small hit in latency (CAS 5 in this case) is better. IMHO the differences are minor and I would go with the most stable setup.

interesting question.

Ok. you must try overclocking the RAM memory... DRR400 is very slowly for now..

I´m test ( 1 year ago) a intel 820 D since 2,1 Ghz.. ( underclocking ..) to 3,5 Ghz. ( overclocking) his speed nominal is 2,8 Ghz...

the best result in fritz test was in "overclocking" combinate...

My ram was 533 Mhz.. ( kinstong VALUE) ... and run very well in 3-3-3-9-4 ... ( nominal value was 4-4-4-12)...

if UPS the ram to 600 or ups this I need up a little overvoltaje... not problem with this baceuse I have a temp sensor in ram...

ram voltaje is in my case the 1,8 volt... and when I overclocking this and test a mem86 to test ALL memory previus load the system operation crash in some module chip... UP 1,-1.95 not crahs and I can up the speed more... and when I use 2 volt to RAM not see any crash... in memory... and when I used high speed memory, I´m use 5-4-4-12-6.. and have a perfect results... the diferents among timings ... they are overvalued ....

in that moment you have the limit of the memory.. ( other people use more voltaje... 2,1 or 2,3 for memory )

IN that moment test the CPU and in my case I´m do undervoltaje. because the series 8xx of intel works betweent 1.3-1.4 volt... I´m use a voltaje of 1,25 VOlt and tha overclocking is good..

3,5 GHZ in a CPU of 2,8 Ghz is a lot of overclocking... these cpu are very hot... maybe 150 W... ¡¡¡ I was need a ZALMAN 9500 and a good power supply to test ( silverstone 600 W )

The best result when I use CPU versus others engines is in 3,3 GHz...

I think that in the max speed the cpu and bus have some errors of read-write, and lost some clocks in re-send bytes... in my case the best overclocking was 3,3 Ghz.

in intel dual core due, the overclocking is more easy... but I say you that if you can "use" a memory soo fast you will have better results..

the timing are over-value... they not are important that SPEED of ram..

660 Mhz and slowly timing are better that 400 Mhz .. and fast timings
( you can see test about memorys )

exits a jump since 400 to 660 Mhz... exits other jump since 800 to 1066 Mhz...

remember that modules using a lot of memory load... and a fast read- write are very interesting... timing are important too.. but if you used values very small,. you have a lot ot more "errors" of read-write in RAM and the "result" real works are bad....

if you used a HASD-table very big are bad for fast time game to..

"...the size is not the important thing..."

in other theme the diferents are over valorate too... only 1-3 % of better.

"...speed not is more importan thant knowledge"...

bye, since spain. OLIVer
