That's not a very pleasant outlook :-P </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26320 Tue, 27 May 2008 21:20:50 +0000 InDiSent 26320@http://www.howtogeek.com/forum/ <p>that's what i thought. Hopefully i can build my quad core system this summer if my wife stops spending all of my money, lol. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26319 Tue, 27 May 2008 21:12:01 +0000 The Geek 26319@http://www.howtogeek.com/forum/ <p>No... hyper threading isn't a true CPU, so I wouldn't use the affinity settings at all. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26317 Tue, 27 May 2008 21:00:11 +0000 InDiSent 26317@http://www.howtogeek.com/forum/ <p>ok, so i am running windows xp sp3 pro. i have a pentium 4 3.04Ghz cpu. CPU 0 and CPU 1 is because of hyper threading? Should i set vms to use only cpu 1? Thanks. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26316 Tue, 27 May 2008 20:59:40 +0000 The Geek 26316@http://www.howtogeek.com/forum/ <p>It's more that in case VMware goes crazy and takes 100% of the cpu, I want to continue to have fast performance in the rest of the system.</p> <p>Vista does a pretty good job of threading across multple cores, especially with 64-bit and lots of memory. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26314 Tue, 27 May 2008 20:50:57 +0000 whs 26314@http://www.howtogeek.com/forum/ <p>Any idea how good a job Vista does managing 4 cores. Assuming that Vista does a good job, why would I want to change the core assignments? </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26313 Tue, 27 May 2008 20:45:20 +0000 The Geek 26313@http://www.howtogeek.com/forum/ <p>Everything internally in programming terms starts with 0, although I suppose they could have changed the UI to be more user-friendly.</p> <p>Windows determines all of the threading and processor usage allocation internally, you can just change some of the settings from task manager if you want. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26312 Tue, 27 May 2008 20:39:14 +0000 whs 26312@http://www.howtogeek.com/forum/ <p>I checked some of my processes. Affinity is always assigned to all 4 processors. Is it the task manager now that decides to which processor to assign a process and how good a job does it do?<br /> BTW: Isn't it dumb that the processors (cores) always start counting with 0 and everybody else starts with 1. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26309 Tue, 27 May 2008 20:25:35 +0000 The Geek 26309@http://www.howtogeek.com/forum/ <p>@InDiSent: I simply used task manager to set them... but you could modify the shortcut to run all of vmware with a separate affinity, I imagine:<br /> <a href='http://www.howtogeek.com/howto/windows-vista/start-an-application-assigned-to-a-specific-cpu-in-windows-vista/'>http://www.howtogeek.com/howto/windows-vista/start-an-application-assigned-to-a-specific-cpu-in-windows-vista/</a></p> <p>I haven't checked to see if that will run the virtual machines themselves that way. I need to look into this more... setting it manually worked out fine for me =) </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26308 Tue, 27 May 2008 20:19:11 +0000 InDiSent 26308@http://www.howtogeek.com/forum/ <p>@ The Geek - I use vmware workstation 6.0.3. How do you set the affinity? </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26297 Tue, 27 May 2008 17:45:12 +0000 whs 26297@http://www.howtogeek.com/forum/ <p>With benchmarks it is like with statistics - you first define the result and then you pick the samples accordingly. Dual channels must be faster - but not neccessarily in all instances. It's like with my new Intel Q6600 quad. I thought it would be faster than a duo core in all cases - not so. For e.g. the installation of SP1 it took nearly twice as much time than my AMD duo core. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26289 Tue, 27 May 2008 16:18:25 +0000 ScottW 26289@http://www.howtogeek.com/forum/ <p>We were discussing dual channel memory in another thread and I went to Wikipedia to look for references. They have a pointer to an article from Tom's Hardware Group that says there is little benefit to dual channel memory configurations in the benchmarks they used:<br /> <a href='http://www.tomshardware.com/2007/10/17/parallel_processing/page11.html'>http://www.tomshardware.com/2007/10/17/parallel_processing/page11.html</a></p> <p>It makes me wonder if the whole dual channel thing is a marketing scheme to get everyone to buy 2 DIMMs instead of 1. Have we all been duped? The idea of dual channel sounds good on paper, but I've seen plenty of sounds-good-on-paper ideas that are just hype. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26288 Tue, 27 May 2008 16:14:26 +0000 jraparrish 26288@http://www.howtogeek.com/forum/ <p>That is Awesome, we have a couple of dozen Windows 2003 Servers running on VM Ware and the physical hardware can really get stretched if you don't have the horsepower to run them. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26287 Tue, 27 May 2008 15:39:35 +0000 The Geek 26287@http://www.howtogeek.com/forum/ <p>I looked in the manual, you are correct... I figured it wasn't too important since I'm just waiting for the rest to come in the mail =)</p> <p>I'm running Vista 64-bit, and it's screaming fast... I wanted more memory so I can run more virtual machines at the same time. The quad-core is awesome... I changed the affinity so vmware runs on two CPUs, which keeps my regular system from slowing down while running the virtual machines </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26286 Tue, 27 May 2008 15:35:05 +0000 jraparrish 26286@http://www.howtogeek.com/forum/ <p>I miss spoke, the picture shows you populated A1 + A2, in section 2.4.2 of the manual A1 + B1 is the Dual Channel configuration if you only populate 2 of the 4 slots. But the point is moot if you are going to populate them all. Are you running Vista 64bit? or a Linux Distro? That thing should scream. Great site and Forum. I personally appreciate your work on the site. Thanks. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26284 Tue, 27 May 2008 14:56:39 +0000 xenomex 26284@http://www.howtogeek.com/forum/ <p>Thanks Geek. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26281 Tue, 27 May 2008 13:42:01 +0000 The Geek 26281@http://www.howtogeek.com/forum/ <p>@jraparrish</p> <p>The manual actually says those two slots are A1+A2, even though one is yellow and one is black... but the real reason I put them in those two slots is that I'm adding another 2 dimms, so all of them will be full =) </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26273 Tue, 27 May 2008 10:35:39 +0000 InDiSent 26273@http://www.howtogeek.com/forum/ <p>i didn't even notice that, good catch. </p> http://www.howtogeek.com/forum/topic/geeks-new-computer-memory-configuration-not-dual-channel#post-26272 Tue, 27 May 2008 10:26:44 +0000 jraparrish 26272@http://www.howtogeek.com/forum/ <p>I was looking at the pictures of your new computer this morning and noticed you installed the DIMM's in a non-dual channel configurarion. Was that on purpose? And if so, can you explain why? Otherwise, unless your ASUS board had different directions, the modules should be placed in A1 + A2(Black + Black)for dual channel operation. Your picture shows them in A1 + B1(Black + Yellow). Just an observation. </p>
