Question about OCZ timings
Missileman
Orlando, Florida Icrontian
I just received a kit of 2Gb ATI Crossfire certified. It is supposed to run at 4-4-4-15, but the spd is programmed to run at 5-5-5-16. Now it works fine when I do the override and set it manually, but I shouldn't have to override the spd. It should post and run at the specs it is sold under. This is plain old false advertising. I know all the manufacturers do it, but that doesn't make it right. I buy a car with 300 HP it better have 300 HP no matter what the computer sets the timings at.
Memory is no different. You sell it as 4-4-4-15 PC6400 it ought to post and run at 4-4-4-15 at 800Mhz, not 266 like the spd is programmed.
I ordered CAS 4 800 Mhz RAM and would like REAL CAS 4 800Mhz RAM.

You can't program 4-4-4 timings on the SPD, this is outside the Jedec spec for 800 MHz. You have to have 2V - 2.1V for 800 MHz operation and 4-4-4 timings, all motherboards run 1.8V by default for DDR2 which you cannot control from the SPD.
If you program 4-4-4 at 800, your board would not boot when you first put the sticks in.
SPD is loose for compatibility purposes.
You said they operate correctly at rated speeds and timings, so you received real 800 MHz CAS 4 ram.
I also went back and found all the fine prints. My board is ATI crossfire certified, but not an ATI chipset (badaxe2)
The RAM performs better than I expected so I was actually okay with it, but I am constantly tickering with my settings so I like as much as possible on auto so i don't have to go set it after a cmos clear because I usually forget when I'm in that frustation mode
Thanks for the info.
Will have to go check out the spec closer next time.
These are really good sticks and you could see DDR-1000 out of them at 5-5-5 timings.
5-5-5 is the Jedec Spec for 800 MHz at 1.8V, that is why the SPD is programmed that way.
These offer better than Jedec spec at 800, but need more voltage to get there.
I wouldn't mind if you changed the title of the thread Missileman as it is very misleading, unless you really are upset with us for some reason.
I may be a bit slow, but I used to have edit buttons and now they are gone.
One of the mods can maybe delete it.
I have the edit button on this post. Mods must have a time limit turned on.
