I have a GA-EP45-UD3L motherboard i went from ddr2 800 to ddr2 1066 my pc still

[thehermit]

any ideas people where im going wrong ? I have a gigabyte mobo I just changed my ram from ddr2 800 to ddr2 1066 cpu-z still shows it as ddr2 800

Check the voltage requirements for the 1066 ram. After changing the voltage, try setting it manually to 1066 if the board permits it, or try a ratio change if your board has them.

Keep in mind that the above poster is correct, your going to have to "make" it work manually as the DDR2 standard is for 1.8v at 800.

boonality is right. There ain't no such thing as DDR2-1066 RAM. Got your attention now, yes?

DDR2-1066 RAM is simply DDR2-800 RAM that has been tested to run at the higher speed, usually at an increased voltage and more relaxed timings.

Whats DDR2-667 ram? or DDR2-533 ram? or DDR2-400 ram?

roonj,

It's just an international standard to be adhered to. It doesn't mean that those speeds don't exist or anything.

Whats DDR2-667 ram? or DDR2-533 ram? or DDR2-400 ram?

Defined in JEDEC standards.

^ Which list standard voltage at 1.8v (DDR2) or 1.65v (DDR3) while most of the high performing DDR2 RAM runs at about 2.0-2.3v. The BIOS provides 1.8v by default (with out taking in to consideration XMP,etc).

 

[thehermit]

I have the voltages running at 2.0
its gskill f2-8500cl5d-4gbpq
and the timings are 5-6-6-18 at 2.0v

to: thehermit,
those fiqures match the spec's I've now seen, the timing is suppose to set for (2) also not (1). Are you now using those settings and are they working for you?

Unrelated, the Jedec specification standard voltage for DDR3 is 1.5v not 1.65v.
