Opteron Memory Timings Tested

Reviews

When building any modern computer, the choice of which memory to use is a major consideration. After all, why spend a mint on the latest CPU and motherboard, only to slow it down a bit with anything but the best memory available? This was definitely a big consideration when we began work on our Ultimate Linux Workstation. So, the question before us was, “Which memory should we buy and would the expense of the lower latency memory be worth it?” To answer this question, we went in search of the three standard CAS latencies that you will find for DDR memory and we put them to the test on our new Opteron testbed.

For this testing we went out and found memory specifically designed to run at the settings we wanted to test. This made the testing more real world, since these modules represented certain price points.

For the CAS 2 and CAS 3 memory, we turned to Corsair and their XMS and Ultra-Stable server memory respectively. For CAS 2.5, we called up Kingston for some of their HyperX registered ECC modules. Both companies were more than happy to participate in our testing. This also gave us an opportunity to test out these memory modules for compatibility on the new Tyan Thunder K8WE motherboard.

First of all, were all of the memory modules stable? Yes. All modules made it through all stress testing without error. For our testing we ran all modules with ECC enabled. This is a requirement for our CAS 2 modules, so we thought it was only fair to run ECC on all modules. We've found through internal testing that ECC does not appear to measurably hurt performance. The only hitch we found in testing is that Kingston's modules did not SPD (Serial Presence Detect) at the advertised timings. This was not a huge issue though since we were able to set these manually. Both sets of Corsair's modules set themselves to the timings expected.

Now let's show you our setup: Link to setup, tests and results.

CentOS 5.11 Officially Released, Probably the Last One in the Series

As you all know already, CentOS is an Enterprise-class Linux Distribution derived from sources provided by Red Hat. This is the eleventh update for the distribution and probably the last one. It features all the packages from all variants, including Server and Client, and the upstream repositories have been merged into a single one. Red Hat announced less than a month ago the release of their last update for Red Hat Enterprise Linux, 5.11. It stands to reason that CentOS 5.11 will also be the last update in the series.

England's Healthwatch switches to open source CRM

England's Healthwatch organisations are now using CiviCRM, an open source solution for customer relationship management. "Open source affords access to a wide community of developers, which means that the software continues to develop and security updates and bug fixes are regularly rolled out", explains Tim Schofield, the organisation's interim systems manager.

Opera for Linux to Get a Stable Version Soon

The Opera browser is now based on Chromium and this simple fact has delayed the release of a stable Linux version for more than a year. Now, the Linux platform will finally get a release and some final touches have been made to the client. The developers have improved a number of features that are already available in the browser. For example, users will not be able to drop a PDF file in browser tab that already has a similar file opened, deleting the entries in History now works as it should, the correct font is used all the time, and the new Bookmark feature that has been recently made available has been improved.
