Hello, as above I want to add to my HyperX 4GB (2GBx2) PC2-8500 1066mhz KHX8500D2K2/4G (I believe)...2GB (1 stick) of PC2-6400 800mhz HyperX KHX6400D2LLK2/4G!

PC2-8500 can run @ 800mhz (1.8v) and 1066mhz (2.3v) - I believe 5-5-5-15
PC2-6400 needs 1.95V at 800mhz and 4-4-4-2 I believe!

So will it be compatible if I run them together at 5-5-5-15 1.95V @ 844mhz (844mhz as my CPU is OC'd)?

Thank You!
 
should be fine if the pc6400 stuff will take the overclock of 844, might be better starting at 800 to confirm it works ok first then see about the overclock.
 
Hi Wayne,

Found time today to Run Prime95 ... Run for 7h 43min and system was stable, I believe system stable, however dropped FSB, From 420 to 417 as before failed prime95 in 4h !

SO I am happy ;)
 
^^ :p :p :p :p
well well, Downloaded Memtest, burned to DVD-R, booted PC,..It was loading about 20-30min than black screen, Than I restarted PC, gave it second go, same!

After I restarted 3rd Time Pc went straight to the Z FLASH MODE, saying that Bios is corrupted and I should re-flash it, I ignored couple times, but today had same issue.
I reinstalled bios, thanks god my OC settings left and all other settings in Bios!
 
Not sure about "toasty" forgot that after each memtest you've got to touch them :p :p :p :p .. will try other time, will also put back OCZ Ram cooler on and report back ;)

However, running all this days, system 100% stable, did other stress tests, plus gaming!
