a 2x2GB DDR2-8500 (1066Mhz) CAS5 Kit that runs 4-4-4-12 @ 475FSB?

[jeeka]

Hey guys,
I wanna get a 2x2GB Kit that will allow me to run 4-4-4-12 @ 475 fsb. The only CAS4 RAM that I see around tops out at 800Mhz and might have a hard time reaching DDR950 specs (475fsb)...

I was wondering if it was plausible to get some 1066Mhz CAS5 RAM and underclock it to 950Mhz to get it to sit at CAS4...I want to maintain the 1:1 ratio, unless someone can enlighten me that q6600's like as much RAM bandwidth as they can get and being at anything higher than 1:1 (i.e. 5:6, etc..) has no effect on total system performance....

Just wondering if sitting at 1066Mhz CAS5 is "better" for my 3800Mhz q6600 than 950Mhz CAS4 settings I currently run...

I know with Core 2 Dual Cores, CAS latency and RAM bandwidth are not the most important settings with this architecture, based on benchies some have run, no noticeable losses in performance, or negligible, but Quads might like to fatter fsb, RAM Speeds, lower CAS, ....

I run a P5K Deluxe.
Thanks!

From my mild experience and others more advance experiences.
Having to keep 1:1 is utter bull.

Keeping in mind the OP used to work in the memory industry.


You can see the screenshotted results scattered through the pages.

EDIT:
And wow, I forgot to mention it only applies to Intel chipsets, not nvidia.

You will be better off sticking with your 4 sticks of HZ. I see in you sig you are running them right now at 475 1:1 with 4-4-4-12.
got to the 5:6 divider and run them at DDR 1140 instead of the 950 you are at now and set your timings at 5-5-5-5. You will gain 1000 cpu points in aquamark
If you can't get it to run at 1140 5-5-5-5 then try 5-5-5-8. If any thing that high is out of the question then run your machine on the 9x multi at 423fsb again with your mem on the 5:6 divider with your timings at 5-4-4-5
This will give you more speed then you are getting now at 4-4-4-12.
