1600mhz RAM CL7 or CL9

post #1 of 10
Thread Starter 
Hi,

I currently have 4gb of Corsair XMS3 1600mhz RAM and its rated timings are 7-8-7-20 1.65v. I'm looking to get a further 4gb however this RAM looks to be discontinued and replaced by RAM with timings of 9-9-9-24. I can get hold of the CL7 version but for a premium as its in such short supply.

My question is - do I bite the bullet and get 2 more sticks of the CL7 version? Or replace what I've got with 8gb of eg Corsair Vengeance Low Profile 9-9-9-24 1.5v which is actually cheaper than buying another 4gb of the CL7 stuff? Is there any performance difference?

2x4gb would be better then 4x2gb sticks.

I'd say go with the 8gb kit as the ram is paired, and therefore is guarenteed compatible as well as working properly in dual-channel configuration.

Ok. For the Phenom II x6 and have 4 sticks of ram. It will not hurt anything. The phenom II x6 can handle 4 sticks at 1600 and will not hurt you ocing the cpu.

They should work just fine. If by some chance your motherboard doesn't have a 1.35v option, just use 1.5, it won't hurt anything.

I'd go with a set to replace your existing memory with a 2x4GB set. Those XMS3, even though you could still get hold of them are far too expensive for 4GB DDR3 of memory. And considering the price of ram these days, it's daylight robbery.

Uh, not necessarily tongue.gif
From a RAM performance standpoint, most 4GB DIMMs are binned lower and do not overclock as well. A 1055T will have no trouble handling 4 DIMMs at DDR3-1600.
If you cannot find the same kit, try and find something with the same speed, timings, and voltage (even if it is a different brand). Not that going with a 2x4GB kit and scrapping this one isn't a bad idea either, if the need for more RAM outweighs about 500MB/s in extra bandwidth and a ~50% reduction in latency.

Thanks all - I've decided to go with 2 x 4gb and have ordered the Corsair Arctic White 1.35v ones. Which obviously means I can sell off the RAM I have now. All makes sense from an economic standpoint!

Update: The new RAM just did not want to play ball: http://www.overclock.net/t/1165684/installed-new-memory-now-i-cant-overclock

Very strange. So I guess I'll stick with my old RAM and send the Vengeance back.
