DDR 400--Or, Does This Sound Right?
I bought my AMD64 system in early May. It has a 3200+ processor on a Gigabyte K8N Pro MB with 1 GB of DDR 400 RAM. For over two months I've been running SuSE 9.1 in 64 bit mode with no problems. Suddenly a week or so ago I encountered system freeze ups to the point where I couldn't even run Knoppix anymore. Long story short, the repair guy at the local shop I bought the box at said that on AMD64 systems, the DDR 400 memory needs to be underclocked down to DDR 333. "Why would it work for two months with no problem?" said I. "That's the way they are." said he. Does this sound right? Does anyone here have DDR 400 RAM on their boxes that work properly? I haven't even gone into how they snookered me out of $100 for a new hard drive when we thought the freeze ups were related to hard drive access. So you can see the reason I'm a little sceptical. It just doesn't sound right that you can't run DDR 400 on 64 bit, but who knows? (Hopefully someone here, which is why I'm asking... :-) -- Bryce Hardy (Santa Rosa, CA USA) cygnia@sonic.net

It does not sound right. But it is possible that the memory is not ok. Why don't you load the SuSE install DVD and run the memtest there. It will show if there is an issue with the memory. And if yes, your local shop should exchange the faulty ones... You could also replace them for testing with other DDR 400 RAMs, to see if teh problem goes away. And again, if yes, your local shop should exchange the faulty ones... I had a similar problem once where it helped to simply take the memory our and put it back again, as if somehow a contact would have been not good somewhere. HTH, Matt

You mention lock-ups related to hard-disk access? I had a similar problem with our new Dual-Opteron Servers a few months back. Memtestx86+ ran for 12 hours with no failure. However running "bonnie" (hard disk benchmark) my system FROZE (AMD64 SLES 8). Sometimes it would freeze at the start, sometimes in the middle of the test. Just make sure to give it the number of megabytes of RAM you have as an option (i.e. bonnie -s 2048 for a 2 GB RAM system). I tested the ram chips one at a time with bonnie and sure enough traced it back to ONE faulty stick of RAM. We'd ordered 3 servers and it was just my bad luck that I picked the one with the faulty RAM to install FIRST! :) -----Original Message----- From: Matt T.

Don't get too tight performance ram, go with a manufacturer that sticks to jdec timmings. i.e Samsung. Not Mushkin/OCZ/Corsair. The CAS Timmings on any of the "Performance" Brands tend to run too tight for many of the amd 64 chipsets. This is especially true of the nforce3 150's and the k8t800 chipset based Mobo's. I don't know if the nforce3 2xx series are any better. On Wed, 2004-07-28 at 16:38, Matt T. wrote:

My MSI K8T800 FIS2R mobo was rock solid with Mushkin DDR 400 222 Special (CAS2-2-2 timings) in Win32/64, FC2 and Suse 9.1 x86_64... Joel Wiramu Pauling wrote:

Bryce, I run an Athon 64 3200+ running on an Abit KV8 Max3 motherboard. I have 2 sticks of Crucial DDR400 memory installed and the box works fine. However there is a restriction documented by Abit and AMD that you cannot have more than 2 DDR400 DIMMS installed, adding a 3rd would required the bus speed being dropped to 333MHz. If you only have 2 DIMMS installed then this isn't an answer to your problem, if you have 3 or more DIMMS installed then you are into unknown teritory. -- David Bottrill david@bottrill.org www.bottrill.org Registered Linux user number 330730
Hi Well the latest AOPEN Bios (1.13) for my Mobo (AK86-L) suddenly clocked my 2 sticks of DDR400 ram down to 333. Where is was running 400. Never had a problem before, but this is not a server so it is not running continuously. BB, Arjen

Huh? Thanks for the heads up. About to try upgrading to that bios... - kevin
