memory showing 2 different speeds. Help!

post #1 of 6
Thread Starter 
This is my issue and I only realized it after running a 3d mark bench.



I had to Rma a set of memory sticks. Patriot advised me it would be compatible with my current system. They replaced the 2 sticks and they obviously looked different. I currently have my memory at 1600 in my bios with 9-9-9-24 settings. Why am I showing 2 different speeds on my bench and how would I fix this or do I need to buy new memory or is this still considered normal? Is my motherboard holding me back?

I have two sticks of each:

open/download CPU-Z and show us the memory tab.

I guess when they RMA'd my memory they gave me 2 memory sticks that run at a slower speed after investigating further. My question at this point is how is this affecting my performance and am I better off buying 2 new chips so I can have all 4 running at 800mhz? Since I guess it will automatically downclock all my memory to run at 533mhz each. Whats strange is that CPUZ is showing my memory at 802mhz. According to Patriot they said these sticks would be compatible with my 9-9-9-24 setup which may be true as per CPUZ but what about 3dmark? How is this affecting my performance and should I buy 2 new sticks that can run at 800mhz each or complain to Patriot to switch them out?

You're fine. All 4 sticks are running at their rated speed of 1600mhz 9-9-9-24. When reading the CPU-Z speeds, unless its SDRAM, always multiply the number it provides by 2 to get the actual data rate. Performance hit is non-existant and there might even be an ever so slight boost as the memory is running 2 mhz faster than stock. 3dmark is just being a bit of a retard when it is reading the memory speeds.

Thanks man yea it seemed fine but I thought it was just hurting my bench numbers. Thanks for clearing that up. Do you think I can get higher ram clocks more then a 9-9-9-24 with my current overclock setup?

It possible, but whether it actually happens is something you have to deal with.
