Mixing same speed ram

Hey guys,

I've currently got a 2*4GB kit @1.65V 2400Mhz 11-12-12-31 timings. It has come to a stage now where this is no longer good enough.
I'm now planning on getting this to go with that kit http://www.overclockers.co.uk/showpr...odid=MY-061-TG
The only difference is the timings @ 11-13-13-35
How will this affect stability or should it be negligible?

TA MUCHLY

You will come into problems i believe some ram can work with different timings, but you would have to go into bio's but it may not run right if at all if they where different speeds then they could downclock to the slower rams speed.

That was the plan, no issue when not running on native xmp timings?

Sorry if i wasnt clear. I plan on matching timings on the highest timing. I was concerned about the 2 sticks which will no longer be running their native xmp timings (i.e. timings increased)

if the timings dont match when combining you may get incompatibility if replacing then no problem. Whats up with the older ram?

Again, dont think i was clear enough. This is to add to the other ram. I dont have enough.

motherboard will choose lowest mhz and highest latency by default and just set that on all dimms, in most cases at least.

I've actually done this today on an older system with DD2 ram. Basically I put 4x1GB Corsair ram, 2 sticks 4-4-4-12 800Mhz and 2 sticks 5-5-5-18 800Mhz(set timings in bios to 5-5-5-18 or looser) and while it passed a 24hr test in memtest with 0 errors, it crashed my system every time i tried to open/install any software, but it would not crash under OCCT/prime 95 test .
No matter what timings I would choose it would just crash.
Now I'm running the 5-5-5-18 sticks + another stick I found that runs at 5-5-5-12 natively but I've set it to run 5-5-5-18 and it seems stable so far.
It could be that since the motherboard is quite old it may be very picky in my case but honestly I would just find some ram with the same timings.
