Corsair TWIN2X2048-8500C5D, Timings Question


Recommended Posts

I have a friend that has these memory cards and was wondering if it's possible to tighten the timings on these with some extra voltage from CL5 to CL4.

I already know they run @ 5-5-5-15 @ 2.1v.

Would like to get 4-4-4-12 @ 2.?v or 3v?

They have the optional memory cooling fans on them too so heat shouldn't be an issue. Thanks. ;):

I would not think that you can make such tight timings without quite high voltages. Keep in mind that 2.2V for version 1.xx and 2.1 for version 2.xx+ are the maximum warranted voltages and overvolted DRAM will show the overvoltage characteristics thus voiding the warranty. It's up to you to try for the high voltage tight timings but don't be thinking to RMA if they go bad. Keep in mind that heat is not the only damaging effects of overvoltage. Electrostatic Migration kills more DRAM than heat does.


I'm not saying don't do it, because I do it. Just don't expect an RMA if you kill the DRAM. I've killed more than my share of DRAM looking for the modules that will do what I want. It's a crap shoot and can be costly to find.

I was serious when I said I was asking for a Friend that has this memory. (no offense taken) :p:

I don't use this memory OR I wouldn't have to ask at all because I know what mine can do and what settings work best with them & all are close to Factory Specs...


He (Rich my friend) just wanted to know what it would take for this Dominator memory to get timings of 4-4-4-12.


From what I've researched of others testing these, it takes 2.75v to go to 4-4-4-12CL on memory that has Optimal timings of 5-5-5-15 @ 2.1v in the Dominator Series.

Yea I think it's rather high too. He's better off getting CL4 memory to begin with. ;):


Btw, I'm running 2x1GB Corsair XMS2 TWIN2X2048-6400C4 (4-4-4-12) @ 2.1v

Overclocking my Intel E6700 to 3.4Ghz using memory frequency 667 / 4:5 FSB/DRAM ratio = 852Mhz

Yea I found out that Overclocking your memory does Nothing for Performance & throughput on a Northbridge system. :roll:

It's the CPU/FSB speeds that increase the Memory's throughput & performance! :D:

Yea, I edited my CPU speed because I've increased it to a Stable 3.4Ghz...hehe & still at 2.1v on the memory!

This is not true. The difference between 3.6Ghz and 800Mhz with 4-4-4-10 and 3.6Ghz and 1300Mhz with 5-5-5-15 does show an improvement of ~5 - 10% on most applications. On memory intensive application work, such as rendering DVD VOB to AVI, WinRAR, etc. you can easily seee 15%. If you run multiple memory intensive applications simultaneously, then the difference is even more marked, especially if you set a core affinity to each application.


If all you do is open browsers, play music and videos, scroll through excel, etc. then I would say you are correct but it does entirely depend on the use you make of applications.
