Intel Lynnfield Memory Performance

So you've decided to go for a Lynnfield system? You've read the CPU performance data, dived through the P55 motherboard reviews and decided your old system could use a refresh - after all, you can get SLI or CrossFire now and Windows 7 with DirectX 11 is out. But, you've been using DDR2 since the AM2 socket arrived, so you finally need to invest in some DDR3 memory!

But, what type? High speed, low latency or both?

You'll have noticed a significant lack of memory reviews here on bit-tech, or even if you read Custom PC magazine. Truth be told, not many of you read them and they take ages to write, so we stopped doing them. Memory is boring after all and that is why we're doing this feature - it's not to tell you how Lynnfield compares to triple channel Core i7, or popular Core 2 and DDR2, for that you need to read our CPU performance article - it's to inform you of what the memory differences are within the Lynnfield platform.

With that, you'll be better informed for future purchasing decisions. Because memory prices change on a daily basis, it means you can either go to your favourite manufacturer or just find the cheapest kit that suits your needs. We've included a dozen kits from as many manufacturers on the next few pages to whet your whistle, and to keep in mind there's more than just three or four popular brands out there.

We've used the same set of benchmarks and same CPU speed to give a uniform base, so the difference can be easily seen, however due to the limitations of memory straps within the Lynnfield CPUs, we've had to split the tested speeds down the middle: 1,600MHz and 2,000MHz at a 200MHz base clock, and 1,800MHz and 2,160MHz at 180MHz base clock. We've not tested absolutely every iteration of memory out there, but we have covered a nominal 1,600MHz CL9 to the super high-end 2,160MHz CL8.

Very interesting results, I expected a much larger difference than there really is

There's one test they left out that I really wanted to see....video encoding

CoreXE · 3 Weeks Ago

Yeah, there's no big difference, but they should have made separate performance test for all memories.

They did video encoding using Handbrake and H.264. There is <1s difference between all the tested speeds and timings. Go for a super-huge CPU and get some cheapo memory sticks, they said.

From what I have read on other sites the G.Skill Ripjaws play very nice with overclocking and are dirt cheap by comparison to some kits. Directcanada.com had them on for as low as $85!

Exactly what I've been pushing for a while now. Memory is a money sink with no return.

God damn I'd been contemplating picking up that exact pair for awhile now to chuck in the AM3 DDR3 board i got sent by AMD, that linky just made up my mind!

G.Skill is the way to go ever since I abandoned OCZ and Corsair.

In the end, memory is just memory and the heat spreaders are just the packaging.

As much as I try to fight fanboy-ism, I'm a sucker for OCZ even though aside from generic SD/DDR memory I haven't used any other brand. If it ain't broke...

I have had three of their kits (DDR Platinum, DDR2 Titanium, DDR2 SLI), all overclocked by at least 100mhz using stock timings (my current kit hits 160mhz but could go more if it weren't for the dodgy motherboard), they stay nice and cool with the XTC heatsinks plus I have had nothing but great support from OCZ.

Granted if I do make the jump to DDR3 I'll be exploring my options but I'd like to stay with OCZ if the performance and price is right.

Glad I could be of help, Gr3m1in. Let us know how you make out with those screamers!

I was going to get some Mushkin RedLines, but now I'm not so sure! They are $117, and I could save 20-30 just getting something else.
