hi to all,

i have an intel g530 pc with one dimm of ddr3 4 gb of ram

i have bought just recently another 2 x 2 gb of ddr3 dimms (apacer) to install as dual channel on my computer

my pc is running now slower with that dual channel ram !


i have put back my 4 gb of ram ddr3 and my computer runs really fast !

yes, i know that my celeron can adjust the ram at 1066 ghz and my windows xp x86 can see less tha 3.5 gb or ram

as far i know my asus p8h61-m-le motherboard support dual channel ram

thanks ind advance

good morning dear hamluis

i thank you very much for the reply

here are the links

apacer ram ddr3 2 gb ram


corsair value ram 4 gb ddr3


both ram is fully compatible with my asus p8h61-m-le

the corsair is two years old while the apacer two weeks old

the point is when i am running 4 gb one dimm (corsiar) my pc is very fast but when i am running 2 x2 dimms for dual channel ram my pc is very slow !

many thanks in advance

That is quite puzzling.  I've never seen that behaviour.  Normally if there's some incompatibility issue you will get BSOD's etc, not slow running.  Can you download and run UserBenchmark and run it in both single channel and dual channel configurations?  Please post the links to the results when you've done it.  I'm interested to see actual measured memory and system performance.

good afternoon dear friend jonuk76 and i thank you for your kind reply

yes !, a benchmark test ! a very good idea !

the apacer 2x2 gb ddr3 ram dimms are identical

if i remember well some motherboards including my asus do that thing - to run a bit slower if all the ram slots are occupied ! under windows xp x32 bits in dual channel mode

i think this is not happen with windows 7/8

i am running windows xp x32 bits

unfortunately i cannot run that benchmark test you have suggested me since i am doing some important audio/video project that will take some time

sorry for this

i will try to download your benchmark utility for a future use

many thanks
