As u can see from my sig i hav 400mhz ram, but i just noticed 2day when i went into the bios and it showed the start up stuff and said my ram was running at 333mhz i think (its the lower speed than 400mhz) Ive looked in the bios and cant see where i could change it? I know my mb supports it? Any ideas.. -------------------- Asus P4P800S mb P4 2.4Ghz (800Mhz) 1Gb DDR3200 Ram Asus Geforce FX 5600 128mb

Ok ive just opened my case and checked each stick incase i got a dodgy deal when i bought the ram. 1st stick is Kingston and it has 400 / 2.6v or wateva so im assuming thats DDR400 2nd stick clearly says DDR400 on it, but i think its a cheaper brand. At the start up it says the RAM is running at 320mhz. Why would it be doin this, as my mb definately supports 400mhz ram. Do i hav to change sumthin to make it run at this speed? Or should i not bother? although then it would hav been stupid to buy the 400Mhz RAM if it wont even run at that speed? -------------------- Asus P4P800S mb P4 2.4Ghz (800Mhz) 1Gb DDR3200 Ram Asus Geforce FX 5600 128mb

Did you try one stick at a time to make sure the store didn't give you pc 2700 instead of 3200? That happened to me before, it clearly said on the ram pc 3200 but I figured out it was actually pc 2700 and I threw it back at the store manager :D.

ok, ive just taken each one out and ran the other 1 at a time. - ValueRam 2.6v Kingston (KVR400X64...) - KDATA DDR400 2.5v Strange thing is they both run at 400Mhz when there only buy themselves, i tried them both in the 2 slots so 4 ways and they always run at 400Mhz. BUT when i put them BOTH back in no matter which slots they run at 320Mhz ?? :( I looked in the bios and under the _Advanced Chipset Settings_ I have: - Configure DRAM Timing by SPD [enabled] - Memory Excelleration Mode [Auto] - DRAM Idle Timer [Auto] - DRAM Refresh Rate [Auto] I couldnt really find any other relavent stuff towards RAM settings. I dunno wat to do... -------------------- Asus P4P800S mb P4 2.4Ghz (800Mhz) 1Gb DDR3200 Ram Asus Geforce FX 5600 128mb

I don't know how to solve things exactly, but I can tell u one thing: KData mem is the worst mem u can get. I had it installed in 3 pc's and no matter what, all mobo's wouldn't work with it. When i install Corsair mem ... woow: it works! Furthermore, using 2 kinds of memory in one setup might just not work because of incompatibility. Most simple solution: buy another ValueRam 2.6v Kingston (KVR400X64...)

Go to the INTEL site and download their chipset identity tool. If you have the 848P chipset, It only supports up to DDR333.
