FatherTime Posted November 27, 2004 Share Posted November 27, 2004 Ahh, it is so nice to find a thread dealing with my same problem. I've only been dealing with this since May 2004!!! OK, so -- AMD's site says specifically, only use registered memory but YOU'RE saying don't use registered but rather unbuffered and that will fix the problem. I bought my system from Cyberpower and I would think they would have done the legwork on fixing this issue. Instead they let me buy a system that crashes randomly do to this problem. The computer freezes, audible "system falied due to cpu overclocking" and I can't get it to reboot UNTIL I pull out a memory stick and pop it back in again. Please review my rig and confirm for me that I need the above mentioned memory in lieu of what I have now: AMD Athlon 64 FX-53 Corsair XMS 1 gig (2 X CMX512R-3200C2) Asus SK8V MB Geforce 6800 GT Western Digital Raptor HD Also, I have not done anything with the bios. I don't have a clue how to tweek with that and I'm hoping I don't have to. If I can simply exchange the memory, that would be cool. In fact, can I do that through Corsair directly to avoid dealin with CyberPower??? Thanks in advance for your response. Lastly, will I be sacraficing anything with the unregistered memory? Speed, etc? Link to comment Share on other sites More sharing options...
Wired Posted November 27, 2004 Share Posted November 27, 2004 Actually, that was a different motherboard. The motherboard they had was a K8V (Socket 754), while you have SK8V (Socket 940). Your motherboard does require registered memory, and as such, being a different board, I've split the thread. Try these timings: CAS Latency: 2.5T RAS to CAS Delay (tRCD): 3T Row Precharge (tRP): 2T Active to Precharge Delay (tRAS): 6T Memory (DDR) Voltage: 2.75 or 2.8 volts Link to comment Share on other sites More sharing options...
FatherTime Posted November 27, 2004 Author Share Posted November 27, 2004 So, my memory is right because of the MB I have? OK, how do I set these numbers you're mentioning? Sorry, this is all brand new for me. Is that in bios? Boot up hold delete button or somewhere else? Also, I want the memory sticks in slot 1 and 3 right?? Alright, I found all of those in bios and changed them. Thanks. Now I'll put in the module that I removed and see if it's happy or not... cross fingers starting.....now! Well, it booted up and all seems well. Again, this crash happens randomly so if I can go for a few days in succession then I might be out of the woods. Anyway, we shall see. Thanks again.

FatherTime Posted November 27, 2004 Author Share Posted November 27, 2004 Wow, that was a whole 10 minutes before it crashed... Literally 10 minutes in Half Life 2 and dump. This is ridiculous. So, now I'm on 512mb as I've pulled out the other dimm. The funny thing is, it doesn't matter which 512 I pull out. If only one is present, I'm fine. When both are in there I have a problem. Are you sure my problem isn't connected to that other thread? My issue is exactly like that the first guy with the registered memory. Anyway, tweeking with numbers in the bios doesn't seem to be the ticket. Any other thoughts? Link to comment Share on other sites More sharing options...
Wired Posted November 27, 2004 Share Posted November 27, 2004 His problem I believe was registered memory in a board that didn't support it. What is the revision of each stick you have? Were they bought in a TwinX pack? Link to comment Share on other sites More sharing options...
FatherTime Posted November 27, 2004 Author Share Posted November 27, 2004 Hey Wired: I was searching the internet and found this thread from the summer when you were helping some guy named Crodge with the same problem. http://www.houseofhelp.com/v3/showthread.php?p=130525 Do you remember how that turned out?? Anyway, The version # is XMS3200R version 1.1 on both and they were bought through the package deal at Cyberpower so I don't know if they are part of some TwinX. They could be but I don't know. That above mentioned thread seems to suggest my MB doesn't like the Corsair memory but I find it hard to believe. Also, my bios shows from a build in September of 2003. Do you think flashing the bios could be the solution?? That thread above mentioned an old bios that wasn't ready for the FX-53 chip...... Hey - my memory is XMS512R-3200C2 which is registered BUT NOT ECC. Doesn't the FX-53 need registered AND ECC memory??? Is that the problem??

Wired Posted November 27, 2004 Share Posted November 27, 2004 Wasn't helping him, just asked if there was an update. Yeah, I was thinking of that ECC thing as well 'cause ASUS' page about that board states Registered ECC, but doesn't mention non-ecc per se. http://usa.asus.com/products/mb/socket940/sk8v/overview.htm Just checked the list of memory they tested with and it looks like they're all ECC memory.

FatherTime Posted November 27, 2004 Author Share Posted November 27, 2004 Yeah, I'm thinkin that's the deal. I'm gonna call Cyberpower and get them to send me the right stuff. I think it's 2 modules of CMX512RE-3200LLPT. That looks right on the Corsair website stating that it's made specifically for AMD 64 FX systems. Thanks for all of your help. Just think, if Cyberpower had built my system right the first time, none of this would have been necessary. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 29, 2004 Corsair Employees Share Posted November 29, 2004 The CMX512R-3200C2 or TwinX1024R-3200C2 will work without any problem as well with your ASUS SK8V socket 940 with an AMD FX53 CPU. Please make sure that you have the latest BIOS for your MB, and set the correct timing settings which will be 2.5/3/3/6 with a 2.7 or 2.8 volts for the memory module.

FatherTime Posted November 30, 2004 Author Share Posted November 30, 2004 Yeah, you're right. I thought I was onto something with that ECC ram thing but I guess not. I just flashed my bios with the news 4/2004 version and changed the settings to the ones mentioned up above. I think I'm dual channeling and everything so we'll see. One more thing, is there a plus to having the ECC memory as opposed to not and when I get it next week, do I need to change any of the above mentioned settings again??

FatherTime Posted December 2, 2004 Author Share Posted December 2, 2004 Well, bad news --- same problems as before. No success or change. I was hoping for success but none has been found. Let' see, I've flashed my bios to version 1002, I've changed my bios memory information to 2.5 2,3,3,6 with my memory votage to 2.8. I've put both CMX512r-3200 dimms into 1 and 3 and 2 and 4 and eventually, in 10 minutes or a day, I get a total freeze. Only when I pull out either one of the dimms and go back to 512mg, can I boot up the computer. There seems to be nothing wrong with the memory as either dimm will workfine by themselves, only together are they lethal to each other!!! What now, memory controller fried on the AMD 64 fx 53, or faulty SK8v board? This is unbelievably sad. I can't understand how the best hardware in the world from the best companies in the world can be less reliable than a DELL. How is that possible. Ram guy and Wired - I need some new ideas. Please hit me with your best shots ---- fire away!!! (A little Pat Benetar to ease my nerves) Link to comment Share on other sites More sharing options...
FatherTime Posted December 8, 2004 Author Share Posted December 8, 2004 It's been a week since my last post with no response. Is there something I need to do to request a response? I still am having system freeze problems with Corsair memory. Thank you. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 9, 2004 Corsair Employees Share Posted December 9, 2004 Please put the memory module on slot 1 & 3; make sure that you have the latest BIOS for your MB, and set the following settings on your BIOS; Advanced CPU/Memory configuration: Memclock Mode: Limit Memclock Value: 2:1 (400 MHz) Bank Interleaving: 4/Enabled Burst Length: 4 SDRAM timing setting: Disabled/User Define SDRAM CAS Latency: 2.5T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 6T 1T/2T Command: 1T or Auto Master ECC Enable: Disabled Jumper Free/Frequency Voltage Control: Spread Spectrum: Enabled CPU FSB Clock: 200 DDR Voltage: 2.7/2.75 Volts AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!* All other settings should be set to default settings! Then please test them one at a time with http://www.memtest.org and let's make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

FatherTime Posted December 12, 2004 Author Share Posted December 12, 2004 Thanks, RamGuy. I will apply these settings when I return from my weekend trip. I hope they will do the trick. (Some of the settings you have added are new things I haven't tried yet). I will let you know how I fair. Link to comment Share on other sites More sharing options...
FatherTime Posted December 14, 2004 Author Share Posted December 14, 2004 Well, I think I'm solid, finally. No lock ups or anything for the past several days and hours since I input the last settings. I truly think I'm OK now. Time will tell. Thank you again to everybody for your help.
