[Solved] Question about choosing DDR3 memory...

The key question is what mobo do you have?
You need to make sure it is compatible with mobo. Here is the list for the memory you selected:

It might also work on other boards, but GSkill seems to have a fairly complete list of boards for its memory, unlike mobo manufacturers which have a limited number of memories on their compatibility list.

If it is compatible, the memory might be a very good choice since it is at or near the sweet spot for speed and has relatively low timings. But need to know the mobo make and model.

So did you end up going with http://www.gskill.com/products.php?index=223 and http://www.newegg.com/Product/Prod [...] 6813128398

If so ill get that cause im looking for a motherboard that supports 4gb-8gb of CL7 1333mhz ram, and i think i'll get these 2 if you bought them and they worked.

Yes i do see, i just wanna know if the mem i said is supported by the mobo i said. Sum1 said that it is and posted a link, but the link doesnt show anywhere it does haha lol

And here is the link I posted earlier above from GSkil where they clearly state that F3-10666CL7D-4GBRH is compatible with the GIGABYTE GA-MA790GPT-UD3H.

What are you smoking?

Why get memory with such slow timings? The OCZ has 9-9-9-20 compared to 7-7-7-20 for the G.Skill. The OCZ memory is listed at 1.65v while the board spec is 1.5v.

And it is not on the mobo compatibility list, the memory manufacturer provides no mobo compatibility list, and when you use their memory configurator for the chosen mobo, it returns several memory options, but not the one listed above.

But the point is, the memory you linked is NOT in the configurator.

You point out that one with same spec is in - but off course not all the details are included in the spec. Obviously it is a different chip with different number so something is different. What is different? Are you sure the difference will not be an issue?

With all the mobos listed for the chip you linked, why did OCZ not list the subject board if it is compatible? Why exclude it when listing all the rest?

But the bottom line is while cheaper, it has much worse timings that will directly affect performance by a noticeable amount and the manufacturer excluded the subject mobo from the memory configurator list.

That's the Board I've got and it is very solid and offers just about any option you'd need for setting up the Ram timings - I've got a 2x1GB Corsair Ballistix DDR3 1800 cas 8 1.9V kit in it that I've downclocked to DDR3 1600 cas 7 @ 1.7V since it gets better throughput at those settings due to the lower timings - it takes a bit of tweaking in the Bios on anything over 1333Mhz. but the options are all there and fully adjustable.

Yes it does - It is a 790GX chipset with the SB750 Southbridge - I have an X3 720 so it has the unlocked clock multiplier. also has the Hybrid mode for ACC that I was able to use to unlock the 4th core on the chip (was lucky and got a chip with a good 4th core and have been running it now for about a month OC'd to 3.0 Ghz. (200x15) with the 4th core (haven't pushed it further because the stock Heatsink is kind of cheap so waiting to see the actual potential after I get a new Heatsink for it.

In the BIOS it has the MB Intelligent Tweaker which gives you prettyt much everything ( Cpu Clock Ratio, CPU Northbridge Freq, CPU host Clock Control, CPU Freg(Mhz.), Pci-e Clock (Mhz), HT Link width, HT link Frequency, VGA core clock (for built in video), Vga memory clock) and also settings for all of the voltages (System, DDR3, Northbridge, SouthBridge, Sideport Memory, CPU Northbridge Vid Control, CPU voltage Control, and normal CPU Vcore ) - SO pretty much individual control over any of the settings\voltages you want to tweak !
