pretty unusual
did u put dividers on your rams?
try 166 or 133 to find your max CPU speed

Memory divider? timings and voltage?

most D43 need little voltage boost to get DDR500 with loose timing
DT can do better than BT

Try use 2.5-4-4-8 and up the voltage to 2.9v. Then test again and remember 2.9v is the max V u shud put for the d43 chips.

@-vip3rleon9-

try 3-3-3-8 and 2.7v first. if still cannot,try upping the Vdimm. my silly twin stick of rebranded ddr333 KVR can easily do ddr480 at 3-4-4-8-2T 2.9v (didn't dare go higher )

why need to OC your ram since u can OC your CPU already wan ?

no need to oc ur ram la.. used timing enought edi maaa... see ur proc first before ur fried ur ram lorrrr

Nope, dont worry. 2.9v is still in the safe zone for passive cooling.
Its better to try 2.5-4-4-8 before 3-3-3-8 because the difference in the Cas Latency makes more different than those two in the middle.
Some chips can go and some cant depends on the chips itself. So try and experiment yourself.
Higher ram frequency with loose timing is better than slower ram frequency with tight timing.

No worries, just set it to 2.85v then. Now just set it to the highest speed the ram can handle first, then lower your cpu multiplier. We use 8x ok ? Then put it 200mhz, 2.5-3-3-7 and burn in the rams at 2.85v for 1 day.

sorry for the late reply, have been quite busy lately. my apologies.

my rams are currently running @ 2.85v @ 235mhz.

and i just found out that the mobo i'm using does not allow me to choose the CPU multiplier or even the CPU:RAM divider. so i'm wondering how should i set it. only setting i can change is the HT multiplier, but i don't see the point in changing it, as my HT is still safely in the 1800-2000 zone.

what should i do now?

try this,when in bios try to press this two buttons:crtl+F1

it will enable advance bios configuration for sum mobos

btw,as a reminder,keep ur HTL speed sumwhere in 1000mhz range,do not exceed more than 1000mhz coz it might burn ur processor

HT*:hyper transport link

, i used to have this problem, i can't make it 240, but 239 instead...i don't know what i made or how did i, but it solved automatically...FYI, it is good range, but as a safe side...1000MHz~1500MHz should be allright...did i tell you, mine's @320x1x2=640MHz...

yeah...me myself also wonder, what did i did to get it 240MHz...

, i'm on 80GB PATA Maxtor + 40GB PATA Seagate , old fella...

ok...recalled ...
here's what i'm did...(btw, you're using MSI K8N huh?)...i don't think cause of HDD la...
anyway, from what my brother experience (yes, it's my bro's XP -- not mine, i'm on DFI and Asus), anyway...at BIOS, do as usual overclock, say you want to set at 250MHz (which is surely it won't boot), doesn't matter, just set it 250MHz, reboot, but this time, press/hold Insert key, if doesnt work, cold boot then...switch off, while on, hold Insert key until POST appear, it might halt at post, but don't worry, hit F1 to continue...and voila, should be run normally...this method anyway, you have to do it everytime booting your system, from what my bro said, MSI's weakness...

nope, when cold-boot...what i meant was...normally, you just switch on right, so, this time, while switching on, hold Insert key until POST come up...after then, should be allright already...please do note, it'll HALT at POST screen, just press F1, it'll continue to boot...i don't know why MSI behave like this...something like Overclocking Safe Boot...

yeah, but you can try using combination Insert + Reset = Warm boot, same as my bro's PC, if you want details, you can always PM him...ryugan...
