Hi

I'm not an overclocker or gamer. I'm wanting to build a new set up. I only need intel integrated HD 3000 graphics for my needs (therefore need the 2600K cpu) & an H67 mobo. My question is, are there any H67 mobo's that support RAM 1600Mhz as I can't find one? I know the H67 mobo's only support dual memory (instead of triple memory support on the P67 mobo's), does this have anything to do with why I can't find an H67 mobo with RAM 1600Mhz?? Please forgive the ignorance, I'm a complete novice therefore lamens terms would be really appreciated. Please advise, thanks :confused:

Both H67 and P67 only support dual channel, X58 is needed for tri-channel. 1600MHz is considered 'overclocking' DDR3 RAM (even though that's actually the 'stock' speed of a lot of RAM modules) hence it won't be supported on H67 motherboards. In reality you can't tell the difference between 1333MHz and 1600MHz RAM in real world usage.
 
Thanks for correcting me on the dual/triple channel...I've got myself confused with that one! Thanks for the info. If I buy RAM 1333Mhz then is that therefore the fastest RAM available (at stock) on an H67 mobo today?

The mobo I'm looking at is the Asus P8H67-M Evo. Asus states it's RAM supports is dual channel DDR3 1333/1066, so I take it the 1600Mhz RAM is not compatible with this mobo???

thanks snapshot! I've had no joy finding 1333Mhz dual channel 8GB (2x4gb) with low latency, I can only find CAS 9, so maybe a better option would be to put 1600mhz 8GB (2x4gb) sticks in (running at 1333Mhz) as I've seen those with a lower CAS than 9??
 
You might find that 1600MHz CAS9 RAM runs with lower latency at the lower speed. CPU-Z can show you what's going on and certainly seems to show that on my SB rig.

So you're saying that instead of putting in 1333Mhz sticks (as I can't find any 8gb dual channed kits with a lower CAS than 9 anyway), the 1600Mhz CAS 9 sticks running at 1333Mhz will lower the latency?? How does this work? Please forgive my ignorance.
 
The ideal* memory would be :

http://www.overclockers.co.uk/showproduct.php?prodid=MY-188-OC&groupid=701&catid=8&subcat=1516

except that it's a 2x2Gb kit. Solution : buy 2 kits!

Seriously, for £34 this is a steal. Google "OCZ3X1333LV4GK" and see what people are charging for this - £137 was the cheapest I could find, where competitors had any stock. (Basically, OcUK bought a lot of OCZ stock when they stopped selling RAM, hence all the memory deals).

If you really need 16Gb (4x4Gb) of superfast memory, you'd be better of getting a P67 mobo and a cheap GPU (I read that the 3000 IGP is roughly equivalent to a 5450HD costing ~£30-£40, although I'd want to spend a bit more), and using high clock rate (1600MHz+) rather than low latency. This would allow overclocking the CPU, significantly faster memory, and would likely be cheaper than buying 4x4Gb low latency RAM, if it exists.

Out of curiosity, if you're not overclocking your CPU, why do you need such fast memory?

* It does state "Designed specifically for the Intel® P55 chipset", probably before the H67/P67 came out. It's 1.6V, which should be fine with SandyBridge, although 1.5V is "ideal".
 
Thanks DennisMenace but I would prefer 2x4gb sticks as I'd like to keep 2 slots free for more RAM if needed. I need a lot of RAM as I'll be digital audio recording, mixing & editing which uses vasts amount of memory, as will video/photo editing which I will also be doing.

So are you saying that if I add 1600Mhz CAS 9 sticks on the H67 mobo, running them at 1333Mhz, then the latency will be lower than CAS 9 anyway?? How does this work? :confused:

Yes that's what is being said :)

CAS settings and speed (Mhz) go together, so these are rated at CAS 9 when set to 1600Mhz.

As you want to run yours slower than it is designed you may be able to lower the latency to CAS7 or CAS8.
 
My Asus P8H67 Mobo only supports 1333mhz memory, I was going to buy 1333mhz CAS 9 sticks (2 x 4gb) however it's been suggested that I should put in 1600mhz sticks (2 x 4gb) CAS 9, because although they will only run at 1333mhz, it will lower the latency to CAS 8 or CAS 7, is this right?

It's possible.

Corsairs XMS3, for example, is rated to work at 9-9-9-24 at 1600HMz.

The information stored on the RAM is programmed for 9-9-9-24 for 1333MHz so no different.

Logic says that you should be able to tighten the timings at 1333MHz but you would have to try it.

I may work at 8-8-8-24, for example.

It doesn't really make any difference if it works or not.

If you look at the link I posted above you'll see that there's very little difference in performance between 1333MHz CAS 7, 8 or 9.
 
Thanks for the link Surveyor, it was helpful. Think I might as well just by 1333mhz Cas 9 then if they are cheaper than the 1600mhz Cas 9 because like you say, I'm not really going to notice any difference with slightly lower latency. Sorted!Thanks again.
