Also, Suggest me settings for my 1066 Ram

I'm going to start at those voltages and check they run 24/7 stable.

here are the changes to get to 4.0ghz ..(but we dont want to go that high right off the starting line ....... compare the 4.0 settings and you will compare those with the 3.0 stock settings ...... then you should get a feel for a middle of the road voltage jump from stock to get to some 3.6ghz and 3.8 ghz settings ?

AS per Settings i attached, what do u recommend if i want to keep multipler 8x and fsb 450

**linderman** · 04-10-2009, 04:36 PM

the E8400 performs better with the 9X multiplier

which cpu do you have again .......... the CO stepping or G0 ?

**linderman** · 04-10-2009, 04:38 PM

I would set

cpu multiplier at 9X

CPU frequency at 400mhz

set vdimm ram voltage at 2.0ghz

try that and post back

haywired2002 · 04-10-2009, 04:38 PM

C0. and what settings do u recommend for my Ram...whenever i overclock to 450fsb my Ram Drops to 851mhz..why this happens

**linderman** · 04-10-2009, 04:40 PM

drops because your strap is at 333 instead of 400

**linderman** · 04-10-2009, 04:43 PM

forget at getting your ram to 1066mhz to many fellas focus on that; we buy 1066mhz because its easier to keep stable at 850 mhz and higher ......... not becasue we want to zoom to 1066mhz on the memory .........although when your FSB gets to 4.0 ghz your memory will get there automatically

**linderman** · 04-10-2009, 04:43 PM

try these for 3.6 ghz (always 9 for the multiplier)

FSB: 400
VCORE: 1.2
NB V: 1.1

vdimm at 2.0

haywired2002 · 04-10-2009, 04:54 PM

May i ask..why 9 multiplier is best for E8400 as you mentioned

**linderman** · 04-10-2009, 05:01 PM

the E8400 has been proven to run better and higher on the higher FSB

why would you prefer to run the 8X multiplier ? that method was a carry over from the days when the memory was too slow to keep up with the cpu so they would dumb down the fsb so the memory could keep pace ........ but now the 1066 memory is actually able to go faster than the cpu...... the E8400 even at 4.0 cant out run 1066 mhz memory

haywired2002 · 04-10-2009, 05:09 PM

Can you explain when i increase my fsb to 450, my Ram speed falls to 851 MHZ. why this happend, And as u said i should increase my straps to 400..what will happen

haywired2002 · 04-10-2009, 05:10 PM

At what Condition Ram is Running at its full Mhz, that is 1066?

**linderman** · 04-10-2009, 05:17 PM

actually ...........not very often ......... not sure how to do it on asus boards as I havent overclocked many of those in the last year or so ....... on gigabyte boards they have settings that allow you to run the memory set at more than 2 times the fsb ...........

example = 450 x 2 - 900mhz on the ram

on gigabyte boards they have a 2.40 setting

450 x 2.40 = 1080mhz (but they ofen get cranky and unstable at that)

the cpu and memory run the best and fastest on an equal fsb relationshiop

both cpu and memory at 400-450 mhz .............the cpu gets multiplied by 4 the memory gets multiplied by 2

haywired2002 · 04-10-2009, 05:38 PM

"both cpu and memory at 400-450 mhz " According to this line you quoted,
Am i right if i say...400*4-450*2
that is 1600 FSb-900mhz of Dram

YUP right on the money

haywired2002 · 04-10-2009, 05:43 PM

I read somewhere on net that..For CODs , perfect Dram to FSB ration is 2:4. is it true?..and how to achive it

haywired2002 · 04-10-2009, 05:45 PM

Sorry its 5:4

linderman Moderator, Hardware Team Join Date: May 2005 Posts: 20,437 OS: win 2000 pro / Win XP pro My System	Re: Overclocking Failed , Help Neended E8400 the E8400 has been proven to run better and higher on the higher FSB why would you prefer to run the 8X multiplier ? that method was a carry over from the days when the memory was too slow to keep up with the cpu so they would dumb down the fsb so the memory could keep pace ........ but now the 1066 memory is actually able to go faster than the cpu...... the E8400 even at 4.0 cant out run 1066 mhz memory __________________ I still know nothing and I respect that fact, striving to improve and, along the way, help anyone that comes from the place that I used to be!
