hello guys,

my rig is :
a64 3500+ (120nm)
k8n neo2 platinum
2*512 kingston valueram pc3200 (dualDDR)

how can i o/c my rig considering that my ram cannot work with more than 200mhz?
is there a way to "lock" memory to 200mhz through bios, while the fsb is at ie. 220mhz?
i think i could select memory speed (133,166,200 and auto) but i'm not sure
if selecting 200, would lock it there despite the fsb i use..
and besides that, i couldn't find nowhere any cpu:ram ratio (ie 5:4)

anyone can help?
 
Like he said...The thing is you have a nice high multiplier with the 3500+ so if you leave it stock you wont have to jack the fsb up much...use the 166divider and you would likely be covered to 250fsb...I am sure you wont get that OC out of that chip with the stiock Multi though....

With a 12x you likely will get no better then 215fsb in My opinion...so 5:6 divder will be a big hit...
With 11x you probably wont get better then 236fsb... so 6:5 will get you the closest to staying near 400ddr....

If you can't do more then 2.4ghz then 10x240 would be the ultimate setting....with a 6:5 divider that would perfect 400ddr settings....
 
i'm -obviously- no expert, but why would 166mhz work instead of 200 which is what the ram support?
wouldn't that reduce performance?
i tried setting 200mhz for my ram yesterday and raised fsb to 203 just to experiment,
and ram's speed went up to 203 also. (used cpu-z to check)
how come it wasn't locked to 200?

oh, thanx duvie, very helpful
should i also lower ht to 4x to remain under 1ghz?

NO, only if you get past 250fsb which I dont see happening...



 
this is what cpu-z shows about my memory :

frequence 133 166 200
cas 2 2.5 3
2 3 3
2 3 3
6 7 8


does this mean that when i put my mem at 166mhz i have to
change the timings to 2.5-3-3-7 ?
(as i said currently i'm at 3-3-3-8 200mhz, no o/c)

YES, he should change it to 4x. He's running 5x 😉

Also, when you choose 166 on BIOS, youre not telling the ram to run at 166mhz, but telling it what divider to use, in this case, 200 = 1:1 , 166 = 6:5, 133 = 3:2 and 100 = 2:1. Hope it helps your quest.
 
That is right I don't know why I was thinking he was at 4x and to lower it...I run 3x but it is becuase I am up in the 290's..... Keep the HTT at 800-1000...so basically the fsb times the fsb should equal in that range....
 
Those are what are the rated speeds.....You often times can best those results by manufacturers a bit...I supposedly only supposed to be able to run cas 2,3,3,8 at 217mhz for 433drr yet I have in the past on my abit P4 mobo ran 466ddr with cas 2,3,3,8....It is reading the info off of the eeprom (I think that is the spelling) chip that houses info...the same thing sandra and all those other apps read...
 
after all using a memory divider was no goos for me.

with a 5:4 divider, and clock to 210*11=2310mhz, my system was slower than
using 1:1 and clock to 200*11=2200mhz

right now i'm experimenting 1:1 but since i have pc3200 mem (kingston valueram pc3200)
i'm taking small steps at a time and slowly.
right now running 209*11=2299mhz and it's all stable.

question : do u think it's gonna hurm my system (esp. my memory) to run it at
1:1 with 210 or 215fsb (if it can handle it)
i must say again my ram is ddr400
is there any chance it will by damaged if pushed to run at 210 or more?
will it be fried or sth?
- i haven't change it's volts. running at 2.7 right now -

It is a 6:5 divider not 5:4....200/166 is the ratio and divisible by 33 for 6/5...

That may be at that low ram speed, but I can attest clock speed will trump mem speed....

Drop it to 10x multi with 230fsb and then run 6:5 and it will better...Also at slower clock speed you can likely run tighter timings.....

1:1 is not a target you need to stay with...trust me....


Right now do this

Make sure you have bios 1.3 or newer, preferrably 1.36 bios or newer...

drop multi to 10x
bump fsb to 240
set dram to 166, cas 2,4,4,10, 1t
leave HTT 4x
set vcore to 1.5v with 3.3% over vid...This board undervolts but this should give you about 1.47-1.5v actual....
set vagp to 1.6v
set vdimm to 2.75v

This is all prety safe voltage adjustments...I never have seen this small amount take out anything

This above theoretically is like making a stock 3800+ at 2.4ghz with 400ddr and 980HTT


Edit: 240fsb with a 166 or 6:5 ratio is 6/240 = 40x5 = 200 or 400ddr pc3200....Keeps ram in check!!!! I
 
i currently have bios v1.2
would it be safe to upgrade to 1.3 through msi's live update?
i hear some people have serious problems esp. with v1.4

Yes it is safe....However MSI live update I think is only up to 1.3...

I say Bios 1.36 or 1.37mod was a real break thru for me versus earlier ones....

Go ahead and get a program called winflash 1.51...download it...then go find the 1.36 or 1.37mod bin files...download it...

start winflash and update the bios and point to the directory the bin file is at...I have flashed a few times like this...It is easy and successful....I recommend doing this at defualt speed for you since I dont know what you have verified for stability yet. Also keep background apps to a minimum and have no other programs running....Very easy....It will be a whole new way for you in the future...
 
UPDATE THE BIOS.
Put 1.4 in and you will control more options. Also, the vcore seems more stable than with 1.2 that came from Msi...

Go Here and download the file.
Then use c:\program files\msi\live update 3\flashuty\award\winflash.exe to update it.
 
thanx a lot guys..

and duvie, i appriciate the help and the thought you put into it
about my oc-ing, but to be honest, i wouldn't like to spoil that
sweet 11x multiplier my 3500+ has. not yet anyway.

so, is this really so risky to stay at 209mhz fsb 1:1 on pc3200?
i was actually thinking using 2.75 or 2.8 volts on my mem to see if
i can run 210mhz fsb or a little more.
is this a bad idea?

i wouldn't like to do sth dangerous since i worked my a$$ off all the sumer
to get that rig.
 
Most ram modules of pc3200 are capable of running 2.8v easily....

I think the safer bet is to run you ram at spec and you can do that with the 10x240 setup I have listed. The fact is you haven't thoroughly tested the stability of the ram modules now and there is not gaurantee they are stable at 209 1:1....

I say 10x240 with 166 divider....run the cas timings as listed in cpu_z for 400ddr and leave at defualt or 2.7 vdimm. This is very likely for your chip and the ram is left in spec...And in a nutshell that is the beauty of the ram dividers...
