2000mhz or 1600mhz for 3d work and other general tasks?

Yep, basically the question in the thread's title - Is it worth getting the OCZ 2000mhz 6gb set:

http://www.overclockers.co.uk/showproduct.php?prodid=MY-153-OC&groupid=701&catid=8&subcat=1392

or 6gb of Patriot Viper 1600mhz

http://www.overclockers.co.uk/showproduct.php?prodid=MY-008-PA&groupid=701&catid=8&subcat=1389

I wasn't even going to consider the 2000mhz kit but after seeing the price of DDR3 these days dropping by so much is it worth the extra 20 pounds for 3D work and rendering/encoding?

Thanks

p.s. also would it aid overclocking by much?
 
The only thing thats really making me doubt this is the CAS latency on the OCZ being 10-10-10-20 against the viper's 8-8-8-24. But then RAM isn't really an area where I'm too knowledgable

Well at higher speeds that's understandable. If you downclocked the OCZ ram to 1666MHz, it might run tighter timings than the the Patriot RAM. It just depends if that £20 makes a noticeable difference. Although I'm ordering soon, probably next week so if they don't get any of the Patriot in stock I'm hitting up the OCZ.
 
Personally i say no to both of them.

1600MHz CL 8 = 10ns
and the other is at CL10! no way.

In terms of ram latency i suggest the following. (triple channel)
This one.
OR this one


running that those timings you will get the best possible access latency for your money. :D

by that calculation
cl8 @ 1600mhz is identical time latency to cl10 @ 2000mhz, so it makes no ends.

at cas8 and 1600mhz ddr (800mhz single rate)

8 cycles / 1.6x10^9 = 5ns latency = 10ns if you consider single data rate speed

So at cas10 and 2GHz ddr (1Ghz single rate)

10 / 2x10^9 = 5ns = 10 if you consider single data rate

I guess if he is look for the increased bandwidth from the 2000MHz kit... On that note... I get latency. What does the increased bandwidth offer in terms of real world computing? More 'commands' from a program per second?

I still think there are better kits out there.

Thanks for the replies guys, this is of great help!

The thing is I'm looking to pay only about 90-£100 so do you think I should just get the cheaper kingston RAM and overclock? (CAS 9-9-9-27)

http://www.overclockers.co.uk/showproduct.php?prodid=MY-048-KS&groupid=701&catid=8&subcat=1389

I could maybe squeeze this down to 8-8-8-24

Just to note, the Biostar TPower X58 does have memory issues, hopefully a miracle will happen & we'll find the holy grail i.e. Biostar will fix in bios update.

My OCZ 3x2GB Platinums rated at 7-7-7-24 @ 1600mhz will not run at those speeds regardless of stock or overclock, it will run at 8-8-8-24 @ 1600mhz or 6-6-6-24 @ 1200mhz no problem at 4ghz.

I did try dropping the timings down to 9-9-9-24 & increasing the memory overclock to 1800mhz to no avail.

I don't think its the ram or my bios settings as I've had a good play, will prove my theory when I get this Gigabyte EX58-UD5 on the go. ;)

I've also read about this problem with the biostar's. Have you seen this over on the rebels haven forums?

might help, but im quite sure you've already tried that.

So would I maybe be better off just getting 6gb of 1333mhz RAM with low latency?
