The_Schwarz Posted October 10, 2005 Share Posted October 10, 2005 First off I am posting in a new thread because every other one that is close to my problem is for the most part inactive. I have read trough just about everything pertaining to ZNF3-150 and PC4000 Pro but the solution has eluded me. Here is my story: I have had Chaintech's ZNF3-150 since March of 04 and in that board I am using V 1.2 TiwnX PC4000 DDR500 PRO memory. After BIOS upgrades I got the machine to POST and been running smooth or so I thought until now. I had been running things at default bios settings with little problems. But when BF2 came out I realized I needed to juice up my Video card and with that I decided to also purchase another single stick of PC4000 Pro giving me 1.5G PC4000 Pro. When I put the 3rd module into the machine it would not POST. I tried various pairings and positions until I used one of the v1.2 twinx and the new module v3.2 in slots 1 & 2. and behold the machince posted. Since the machince was running I figured I would juice things up in the bios aswell. I reached 225Mhz 2.8V 3.4.4.8 1T. and the machince posted and ran the best I have even seen. Unfortuanley I had 160 + dollars of memory on my desk not being used. So, I called Tech Suppport at Corsair (Your customer support is the best Customer service I have ever recieved) I talked with Trien (I think) He had me run memtest86 and it showed failings with the old memory. I tried each stick at default settings from each slot 1,2,& 3. memtest returned hundreds of errors when using 1 of the old modules from slosts 2 and 3. The other old module returned errors from only slot 3. Both returned no errors from slot 1. The new module didn't return any errors from any slot. We decided to RMA the old twin x back for V3.2 (Gorgette in the RMA dept thank you very much for your help) I get the new memory and put all three in my machine and BAM!!! Its not posting!!!! I ran memtest again with all 3 sticks in each slot separetly this tme they all returned errrors at different passes during different tests in every slot. Fed up with everything and being the weekend I brought my 3 PC4000 modules to my friends place & plugged them into his board and they run beuatifully tested beuatifully. Where do I go from here? Chaintech support needs to take a lesson from you guys as I don't get any response from there support department. Any advice? Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 10, 2005 Author Share Posted October 10, 2005 Should I drop the dough and get a new MotherBoard if so what would run best run my 3 modules of PC4000 Pro??? I am at wits end here!!!!! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 10, 2005 Corsair Employee Share Posted October 10, 2005 I think I have answered you on another thread. But I doubt you will find any MB that will run 3 modules and over clock. Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 11, 2005 Author Share Posted October 11, 2005 You were right, On the overloading of the memory controller. After weeks of email pounding. I finally heard back from Chaintech this is what they told me: A 3rd double sided memory module is not possible to run due to cpu limitation on the memory controller in the cpu. If you would like to use all 3 memory sticks, you will need 1 double sided memory on the first slot and 2 single sided memory on the last 2 slots. Chaintech Support So I pose another couple of questions to you if you don't mind.... If I wanted to add more memory to my system which would be the best route? I See two options Option 1: If I wanted to start new(Meaning new Motherboard 939 Socket & 939 Processor, PCI Express Video Card etcetera) so I could use more than 2 double sided modules as Chaintech described above. Would my best choice be to get another pair of twinx 512's like the ones I have? Or do I sell the pair I have and buy someother memory module to use? If so what would be best? Option 2: Keep my motherboard/processor setup and sell the pair I have and buy someother memory module to use? If so what would be best? Which option would you go with?? If you bought new what would be the best AMD Board/Processor setup in your eyes???? I thank you so much for your time! Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 12, 2005 Author Share Posted October 12, 2005 I will listen to any readers advice on system builds. If I rebuild my machine I want to get good matchups/pairing on what I put into it this time. And having multiple opinions on products might aid my final decision. Thanks to all who respond in advance! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 12, 2005 Corsair Employee Share Posted October 12, 2005 No matter what MB you get it would be best to use 2-1.0 Gig modules if you need more than 1.0 gig of memory. Because of loading on the memory controller! You may find the information in the Memory Basics Presentation helpful. Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 12, 2005 Author Share Posted October 12, 2005 So an ASUS A8N-SLI Deluxe Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard and A Sngle Pair CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 433 (PC 3500) Unbuffered Dual Channel Kit System Memory Model Twinx2048-3500LLPRO Would kick some tail???

Corsair Employee RAM GUY Posted October 12, 2005 Corsair Employee Share Posted October 12, 2005 Yea thats what I'am talkin about! :cool: Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 12, 2005 Author Share Posted October 12, 2005 Thanks for the link very informative! I will be sure to send friends there.. Why have 4 mem banks if it ends up over loading the mem controller when you use more then 1 pair of DDR?? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 12, 2005 Corsair Employee Share Posted October 12, 2005 All modules can be made using both ranks on one module thus allowing you to use lower cost IC's and some MB/Chipsets will not see the higher density IC's that you would need to use to make a single ranked 1.0 Gig module. The cost of a IC like this at this time would make the module 2-3 times the currant price. Link to comment Share on other sites More sharing options...
The_Schwarz Posted October 12, 2005 Author Share Posted October 12, 2005 I understand the logic behind what you say. Cheeper is always better as it alows the average (Joe Blow) to get their hands on your products. Thanks for the info. Now... to pile it all the info I recieved from you into my own words: And assuming if I were to purchase the ASUS A8N-SLI Deluxe. I could assume: A system running the 2 Pairs of twinX (4X512MB) PC4000 would result in a much slower or perhaps inoperable system. Over a system running 1 set of the new CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 433 (PC 3500). Am I understanding you correctly???? Again I thank you for your time and knowledge!

Corsair Employee RAM GUY Posted October 12, 2005 Corsair Employee Share Posted October 12, 2005 Yes, I have this MB A8N-SLI Deluxe with a FX-55 CPU and it will not post if I install more than 2 modules or use slots 1-3. Link to comment Share on other sites More sharing options...
