actually whats the point of using a diskete or cd to store your bios

u can straight away use abit's bios flashing tool. browse around thier software, u can find it. i think is abit flash menu 4 or something like that

im using mantaray
highest i got was 251mhz
that was with super relax timing
decided to go back to 240 with tighter timing

using tictac's mantaray xt
i can achieve 235. dont want to go higher as my rams suck at higher speed. currently ram's are doing 2.5/3/3/11 which i think brings the best performance ratio that i can have at 235mhz tongue.gif

I still curious bout CPU INTERFACE in the bios. Should i set it disable or enable to get high Fsb? In D26 mantaray XT , the vdimm is 2.4-2.7 only? Not 2.9?
*
Leave CPU INTERFACE ON
u get higher memory bandwidht with it and better performance in super pi and overall system performance

if you turn it off, you get higher fsb...but most of the time, lower clock can already achieve what you achieve at higher fsb with CPU interface on.

make sure its on la
i can do 245 with cpu interface. but when i use 230 mhz with cpu interface on, my sandra memory benchmark is higher than the 245( Cpu interface off) tongue.gif at the same timing thumbup.gif

f.e.a.r you are right.
some people so greedy want tight timing lol but never set up properly thier system.

currently using nf-7s plus winbound ch6 512x2(thx kiljim tongue.gif)
both on dual channel doing 225 2/3/3/11 with cpu interface on.

If you overclock and set cpu interface on and your pc survives what ever fsb u get, there will be a noticibale difference in sandra memory benchies and overall benchies ie 3dmark and pcmark.

if u set to disable, it will use the stable parameters and less aggresive which sucks

if your pc did not boot up, meaning your pc is not stable in overclock situations. Imho try setting your system to default and change fsb and timings to suit 200 mhz first.
see if boot, if yes then slowly increase with cpu interface on.

it will be better i tell u

lol

if disable cpu interface should be better stabilty

coz it not using the oced fsb parameter
yup some ppl does! lol

me using kingston valueram 3x512 ddr400 hynix d-43 chip!

doing 2-2-2-11 with 2.9V

cool!

what fsb is that?
and btw what bios are u using?
theres one bios from that dude that created the manta rays...that allow u to hit insanely high fsb's and stable but the benchmarks would lower eventho u hit tight timings and stuff.
forgot edi what bios....cpc on and cpc off if im not mistaken. Always get the CPC ON ones....those are the real performance. CPC off will let u hit crazy speeds but in sandra memory benchies..u can see whats the real difference between cpc on and off smile.gif

no need to fear the temp,,,,, the max is 80!,,,,if u do 70 it is just fine.

BTW: the PSU  fluctuation is crap! well im running my rig in rm 45 450w PSU.... and the

+12 = 11.80

3.33 = 3.22

and can oc sky high no prob at all,,,,

what is  "fluctuation mod",,,explain please!

BTW: full system spec is at my siggy!

once i hit 2.54ghz on my axp tbred at 1.9 volts
my enlight 420 watts could not take it anymore
keep restarting laugh.gif

peice of shit of a psu

the rams are okay at 2.9 volts
those that need cooling are those running above this voltage like 3.0-3.2
2.9 is okay for daily operations
my ram has been running 2.9volts for ages and without problem.

actually its not a bug
nforce does not use the -5 volt rail but it reads it anyway
those acbel oem's dont provide you with a -5 volt rail

it does not do anything la..dont worry...even if its 0, its still okay...only those annoying alarm beeping tru that abit application

by feeding more voltage into chipset,
u can push fsb further

sometimes when you reach max fsb without any voltage to the vdd(chipset voltage), u cant go futher....but adding maybe 0.1 or 0.2 volts u can go higher

it depends relaly on your rams wether they are able to go to that level.

but with all hardware, more voltage leads to shorter lifespan

by increasing voltage to the chipset..which is the Northbridge, it will help u achieve that mhz u want to squeze out.

try achieving maximum fsb stable under prime, increase vdd voltage, and pump 2-3 more mhz..it should be stable....(this is theory ..i dono how much would you be able to get out of your board..try yourself)

southbridge i dono got effect or not
but put heatsink also there tongue.gif
for northbridge, a cm blue ice will be enough.
else u can get teh zalman heatsink for 25 bucks. not sure whats the name and use 40mm fan on it

stock fan + camayam psu + mix ddr module +ori bios = you make me laugh if you wanna oc this type of system..

but you can easily go for max 210x11 . with 1.8 vcore.

1st get a new high perfomance HSF dude...
*
stock fan plus 1.8 volts?
lol u make me laugh laugh.gif
at those fsb, the system would just shut down

stock fan i think the best would be anywhere aroudn 2ghz.
200x10 is enough...1.65 volts should be enough if ur barton is good smile.gif

lol 2100 mhz @1.65 volts nothing to shout about la
tbred b juihb can do 2.3 at 1.675 mhz

my personal record was 2.54ghz with tbred b nuihb at 1.875 volts
temprature was too hot to handle as i was on globalwin cak 4 heatsink.
