FSB and Dividers: My Findings - Page 3

post #21 of 85
NO, not a hobby. A horror, *cries* I just wanna run my pc at tops and use pretty vista! *sniffle* lol.

OK. I've found out the only way to find my best performanc. I am going to tell you guys all of my options, and you are going to tell me which is best (if possible, and if you want to). Thats the only way....

So noone answered my other question. How many tests does memtest86 need to pass to consider RAM stable?

i assume you have it at 300x10 right now, and that sounds like a great stable overclock. you aren't going to get 400x10 on air. if you are at 300x10, you should be able to run your memory at DDR2 800 with a 2:3 ratio.

THERE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yaaaaaah. You got it now. Thats it... thats exactly what I am trying to find out. You said 300x10 with a 2:3 ratio.

What I want to know, is should I lower the multiplier to attain a higher FSB and use the extra mhz in my RAM (that allowed me to attain that 2:3 ratio) to make a 1:1 ratio, or should I keep it exactly as you said???

That is exactly what I'm trying to find out, but noone understands me!!!!

What I do know, is that: (all at 3.0 ghz)
-higher multiplier is more stable
-pretty sure higher multiplier gives me more heat on CPU
-lower multiplier is less stable
-7x doesn't even work past FSB of 1473 (don't know why, check out my other thread about it) and 7x offers me the best FSB and RAM mhz with the 1:1 ratio
-9x I can run a 2:3 ratio
-10x I could probably run a 5:4 ratio
-8x fits perfectly with my RAM in sync mode (800) but no overclock

I actually don't have it at anything right now, I dont know what multiplier to use. If someone would just tell me the best multiplier to use for my scenerio, it would make me feel alot better, even if your flat out wrong on the multiplier lol

300x10 on an E4400? What are you guys talking about? I'm lost.

Groggs, i'm very sorry we hijacked your thread.

Ellipsis, i think 10 is the default multi for his processor. if it is, i was just trying to recommend a good OC with his stock multi to get him started.

Black, i already gave you a recommendation. try it and see if it works. 300x10 FSB with DDR2 800 mem speeds.

Yes, 10x is the default multiplier on the E4400. I just looked it up. I was thinking of the E4300 with the 9x when I posted that. I was more lost than I thought I was. Sorry for the interruption. Carry on.

as paul was saying there you don't downclock your system to have a higher divider. this is like saying well I want to lower my fsb down so I can have a cpu multiplier of x9 vs x7. you just don't do it that way.
but there are many out there like me who reach the FSB limit of their motherboard but the ram has more room to go. like on my motherboard 450mhz is about the max I can push it for everyday 24/7 use. sure I can go a little higher but it gets iffy after that on some things. so if I leave my ram at a 1:1 ratio I can only have a memory speed of 900mhz. should I leave it there cause that is optimum as you say choggs or would you say a 4/5 ratio would be better? with my ram running at 1125?

that is the point of running that divider. to get your memory to go as fast as it can, even more so when the fsb of your computer is going to limit how fast your memory can go.

the point of the divider IS NOT to lower your fsb and cripple your performance just so you can run a divider.

honestly you need to think about that divider and why people use them and why others do not. it isn't a matter of efficiency (ie. mb/s per clock cycle), or so they can lower their fsb it's all about getting that extra bit of performance you can out of your computer by clocking EVERYTHING as fast as it can go.


so far all you have shown us is that by lowering your FSB will hurt performance.







now for my test and I would like you to prove me wrong on this one.
take a p5b-dlx/wifi board or hell even try it on your board. first clock the fsb up to 450mhz and run a 4/5mhz divider so your ram as it 1125mhz. now reboot go into the bios and clock your fsb up to 562Mhz so you can run your ram at 1:1 ratio. what it didn't boot? mmm.. wonder whats faster the 4/5 ratio at 450mhz or the computer that won't boot at 562mhz?


that's a tought one isn't it

lol. So basically what your saying, is, if I can make my pc stable with the highest fsb (lowest multiplier stable) I should run my RAM synced (1:1), but only if synced maxes the RAM. This is preferred over running your fsb a little lower with a higher multiplier to achieve a higher FSB to RAM ratio (maybe 2:3 or 5:4).

Applied to my system specifically, here are my options (and this is kindof what choggs was trying to test)
It's simple, really:

Which is best(rate 1-4)?: *remember, stock 10x multiplier, RAM DDR2 800, overclockeable to I'd say 920mhz max...and CPU must run 3ghz, and timings may be able to run tighter with lower RAM mhz*

#1
7x multiplier
FSB 1715
Ratio 1:1
RAM 857

#2
8x multiplier
FSB 1500
Ratio 1:1
RAM 750

#3
9x multiplier
FSB 1334
Ratio 3:2
RAM 889.33333

#4
10x multiplier
FSB 1200
Ratio 3:2
RAM 800

Overall here's what I thought
#1-1st best
#3-2nd best
#2-3rd best
#4-4th best

Please consider all aspects, like stability, speed, performance, parts lifespan, voltages, heat output...etc


I know that may be very hard to do, but give it a shot.
Much gratuidy (butchered that) for all who helped me out +rep =)


Answer that question and I promise I'll shutup

I have tried running all of these and they all run stable. Haven't messed with the timings on all of them, though.

#1 bothers me because you're lowering the multi so much. i don't think your motherboard will like that. i don't like #2 because that's the only setup where you're actually underclocking the memory. with #3 i don't know if your memory will be able to handle it. i think #4 looks pretty solid. i'm a pretty conservative overclocker though.

another option is to just set everything to 1337. it won't work, but it will look really cool in your BIOS
