clock speeds

[DominicNikon]

this evgas page says the mem clock is 6008 and when i load up evga gpu  software it says 3004mhzs why is that?

delet

DDR= Double Data Rate. So double that 3004MHz and you get the effective clock

 

For GDDR5 the operating clock is actually 1/4 of the effective clock, just so you know. Most programs will report the clock without double data rate, which is half of the effective rate, which is advertised.

Yes, this... Not the first response lol

[Senzelian]

do you seriousley think it will be EXACTLY 6008 dude.. its just a estimate

And you OC it...........

There is a little difference between 3004 and 6008...  :lol: 

But as Oshino already said, it's because of DDR. Completly normal.

im confused... watdafaq I don't even understand what I typed

so false advertising? 

[Oshino Shinobu]

so false advertising? 

No. It's just how GDDR5 operates. Same with Normal RAM, its actual clockspeed is half of the effective speed. 

 

GDDR5 actually has 3 clock speeds (which are measured) if you get technical, but I don't want to go into detail about it, it's confusing. It's not like EVGA is quoting a higher speed than it's running at, they just quote the effective clock (as do all manufacturers)

Yes. Just double it and you'll get the effective clock speed. If you look at your RAM speeds in CPU-Z, you'll see it is quoted as half the speed that they say they run at. That will be the actual clock speed, but because of DDR (Double Data Rate) the effective clock speed is actually double that. (So 1600MHz RAM will show as 800MHz or so in CPU-Z, but the effective clock is still 1600MHz)

my ram in cpuz is 1299 when my mobo bios says 2400

[Oshino Shinobu]

my ram in cpuz is 1299 when my mobo bios says 2400

Yep, that's about right. 

[DominicNikon]

Yep, that's about right. 

ok
