AMD 890FX overclocking and memory performance

Posted on 27th Apr 2010 at 12:26 by Richard Swinburne with 3 comments

Today sees the launch of a new six-core consumer CPU from AMD, the Phenom II X6 1090T Black Edition, and new high-end motherboard chipset, the 890FX.

As you'd expect from a big launch, there's been a lot of jostling for position behind the scenes, especially here in Taipei, Taiwan. As it's a high-end launch, the various motherboard and memory companies involved have been checking out how the new chip and chipset fare with overclocking, and I dropped by G.Skill's offices a couple of weeks ago to get their impressions of AMD's new kit.

At the time, I filed a story about G.Skill's latest 2,500MHz DDR3 but I also had the chance to see the Asus M4A89GTO Pro (890FX/SB850) running four sticks of DDR3 at 1,800MHz, with timings of 6-8-6-24-40-2T.

The overclocked test system used the latest Phenom II X4 965 Black Edition C3, however we also saw it achieve similar memory speeds using a Phenom II X2 555 Black Edition too. The higher frequency is easier to hit with the latest C3 stepping CPUs thanks to AMD’s refinement of its CPU-NB link, but if you have a “good” C2 it can hits these speeds too.

G.Skill were keen to point out that the CAS 6 isn't achievable with every 890FX board at launch, although when as I visited a couple of weeks before the launch, the company's reps told me the FAE teams at each motherboard company still had time to tweak and tune their BIOSes.

4GB memory kits will be available soon and should have either Perfect Storm or Trident heatsinks attached, but the company is as yet undecided about upcoming ranges. As for buying an Asus M4A89GTO Pro - well, when AMD launches its 890FX soon, then you can get one! Let me know your thoughts in the comments.

1.35V DDR3 memory: how much power does it save?

As soon as Kingston admitted to providing Intel with its 1.35V DDR3 at the IDF Clarksdale demo, we started hearing the buzz from more companies such as G.Skill Press Release, all announcing low voltage DDR3 arriving very shortly.

But what does the drop down to 1.35V bring you?

Lynnfield Lab update

Yeah I'm going to tease you all a little again.

We've been running numbers for the last two weeks for both magazine and online coverage of Lynnfield - you'll get the full package all together in Issue 74 of CPC, and of course, for bit-tech we'll be there with the info throughout September (depends on Intel's NDA as to exactly when). Custom PC readers will get a different experience to those just reading bit-tech, but we've carefully designed it so everyone will be informed.

On the test bench has been all the upcoming Lynnfield CPUs - retail boxed ones - and a selection of P55 motherboards, including the MSI P55 GD65, Gigabyte GA-P55-UD5 and Asus P7P55 Deluxe with the MSI P55 GD80, Gigabyte GA-P55M-UD4 and ECS P55 (possibly) reviewed at a later date.

The death of Elpida Hypers

The buzz in extreme overclocking circles recently has been about DDR3 memory featuring Elipda Hyper ICs coming to an early death. In response to this, several companies have stopped selling very high frequency and/or very low latency DDR3 products built with these ICs.
