holy sh- i just tried to replace my DDR266 ram with the new DDR400 KVR and it cant boot up came out saying some system32 file is missing

now i've set it back to the original 266+400 and it works fine whats wrong???

try to boot with 1 stick of ram, it can boot then put in another 1. maybe you can try to switch the ram or slot. hope it helps.

ok..now i'll try to switch the slots..if still cant then maybe i put it all 3 sticks of ram and see what happens wish me luck

haha.....all the best.

=.= i managed to boot up at 1.5gb of ram...used the 1st 2nd and 4th slot.when i tried the new ram only 1 piece[512mb] came out the bsod


edit : now can run 2 pc DDR400 but in slot 1 and 2 , not dual channel gona try now to dual channel.

btw my speeds now is DDR375 on divider 4:5 and superPI is 59s [1s slower then my old dual channel rams]

1.5GB is not dual channel so bandwidth will be slower than DC

Run memtest see got errors or not

nope cant run dual channel at all looks like i've gotta change the ram..lolz now my bandwidth is like 2400mbps only but 1.5gb ram DDR300

u mean u cant run the ddr400 together?? hmm..... try run the newly bought ram, once boot then put it in your old ddr400 ram. Quite weird that. btw, did you set all settings to default timing and clock speed?

yeah now i have 2 DDR400 and 1 DDR266 but i cant run both the DDR400 in dual channel,only single channel damn sad lah...is it ram or mobo incompatible?

same speed and brand of ram usually will not face any compatible problem. my kingmax ram with different pcb color still can run together for 2 years dual channel.

try with different ram slots loh.....
if worst come to worst, use 1 stick of ddr400 + ddr 266
At least still will run DC at 266Mhz stock

yeah.... tighter timing will boost your comp performance. that's why i rather run at 3.82ghz, 1:1, 2 3 2 5 than 3.9ghz, 5:4, 3 4 4 8. hehe

if memory timing not correct, your comp will freeze up OR cant even boot. need to clear CMOS before you boot.

pengster, from your posting..

there is only 2 possible scenarios.

1)i think your old DDR400 is not compatible with your new ram. are you sure that your old DDR400 is Kingston Value RAM? just now during the trading, i gave you my ram box too. you can check the serial num on the box. my ram is 100% Kingston Value RAM.

2)your mobo dual channel have problem.

info: dual channel only works when both of the ram is identical. e.g. KVR and KVR and so on.

edit: Run memtest on my ram, i am sure that your pro is not due to faulty ram. i tested the ram before sold to you just now

to run dual channel not necessary KVR with KVR.
i had once try KVR with Corsair, KVR & Apacer also no problem
but just the same value of both ram, which is 512 & 512

according to some report that i read, if it is not the same type of ram. e.g. brand and so on. there is a high chance it wont perform in dual channel. that's why those branded ram always recommended user to get those 2 pieces kit to ensure 100% compatibility.

if your saying is correct, that's means that there is something wrong with pengster mobo.

even not the same type of RAM also able to run in DC, but doesn't mean all can run.
in this case, i believe the problem come from the RAM instead of mobo.

maybe the spd of the ram is different for both ram. maybe can try adjust the ram timing at c3 or 2.5. by setting loose timing than the ori timing that acceptable for both, maybe can run DC. Just my 2 cents.

okay now im running at dual channel with 1 of my old DDR266 and irangan's DDR400 and no problems..just that when i boot it says overclocking failed and i have to set back to my stock speeds (2.4ghz) now im gonna try with stock speeds but with my other DDR400.

btw my other ram is confirmed a KVR,i bought it and it cam with the same box plus a blue cardboard box

edit : when i tried booting up with both my DDR400 it says NTLDR is missing , press ctrl alt del to restart

OMFG i totally cant boot up my pc anymore im using my laptop atm..wtffff

edit again : now can boot up again with both DDR400 in slot 1 and 2 after i disabled spread spectrum and changed my boot up harddisk priority

edit yet again : now i've succesfully managed to run dual channel with both the DDR400 KVR's but i cant set back my normal 2.7ghz but now 2.52ghz only..bumped up the vdimm n it was able to boot now my vdimm is 2.55v from the stock 2.5v i think.

@pengster

u had learn from mistake!!!!!!!!
u really learn alot . haha

very good effort, dude.

i think there is something wrong with your mobo.
