Rhumba Posted September 30, 2005 Share Posted September 30, 2005 I'm having a problem I've been struggling with for a week now and I'm not sure how to proceed. I received the parts for a new PC about a week ago and put things together. The specifics of the build are: Asus A8N-SLI Dlx Asus En6600TD/256 Nvidia PCI Express card AMD 64 3800+ WD 10k 74gig WD740GD Corsair Twinx2048-3200C2 Sony Dvd writer DRU720A Basic Floppy. Antec Case and is a 400 watt psu from Antec. I started off trying to install Win XP x64. Had terrible problems and decided to go Regular Win XP 32 bit until I'm comfortable with the build. The big problem I saw initially was all of my downloads being corrupted and some random reboots occasionally, it was also corrupting files I would try to move from another PC to this one. I've also installed all of the latest chipset and card drivers. I've also tried itterations of many of the more rescent versions and they all exhibites the same problem. Eventually I figured out that the board was not handling the memory correctly. I used MEMTEST and received many mismatced pair errors. I then came to this board and followed the instuctions and set the board to the following. First i reset the board to the defaults before I started. DDR Voltage [ 2.80V ] - Also tried 2.75V with no luck. In DRAM Config: Tcl : 2.5 Tras : 6T Trcd: 3T Trp: 3T I left everything else at the default. I then ran Memtest and did not receive errors. I only let it run through 1 full time. Yay... I thought. I then went back in and reinstalled everything since I was not sure if anything had gotten corrupted from the other problems. I then started trying to download updates. It was better. But still every other download would become corrupt, meaning that the crc's would get off. I then scoured the boards and saw someone mention that they had changed their mhz to 333 so I figured that I would give it a try. What do you know it fixed the problem, but seems slower. As of yet, I've had no more issues running at 333 now. Been running that way roughly 8 hours. But how do I get this fixed? I bought this assuming it would handle 400 but it does not appear that it does. I have a P4P800 board here with a pentium 3.2 on it. I'm not even sure if this memory is compatable with that board to test it there. Memory Gurus. How should i proceed and as always, Thanks for your help.

gogo Posted September 30, 2005 Share Posted September 30, 2005 I have the almost the same board...you will get corrupted files by using the nvidia firewall. It corrupts files from ftp-servers. remove it and surf safer...:-) gogo Link to comment Share on other sites More sharing options...
Rhumba Posted September 30, 2005 Author Share Posted September 30, 2005 I saw some discussion of Nvdia Firewall. I'm not using the Nvidia Firewall. I've had corrupted downloads with both the Yukon and the Nvidia. The only thing that seems to have stopped the corrption was underclocking the memory.

Corsair Employee RAM GUY Posted September 30, 2005 Corsair Employee Share Posted September 30, 2005 I would check the driver that you are using for the Yukon Lan. There is an update on Microsofts update site that will case problems. Please make sure they you are using the driver from the MB maker only!

Rhumba Posted October 1, 2005 Author Share Posted October 1, 2005 I'm running the Microsoft one now, But i've tried many different versions. I've also tried the nvidia port and totally disabled the Marvell Yukon. Had the same problem. PC only seems to work if i downgrade the memory to 333mhz.

Corsair Employee RAM GUY Posted October 4, 2005 Corsair Employee Share Posted October 4, 2005 Can you test the modules in another system? And with your configuration a 400 Watt PSU may not be enough. And is your PSU ATX 2.0 compatible? Link to comment Share on other sites More sharing options...
Rhumba Posted October 6, 2005 Author Share Posted October 6, 2005 Can I test this with a P4P800 board, that's my old machine? My powersupply is the Antec SmartPower 2.0 400. It looks like it is compatible. http://www.antec.com/us/productDetails.php?ProdID=26400 Thanks, Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 6, 2005 Corsair Employee Share Posted October 6, 2005 Yes that MB or system should be fine to test them in. And you can use the PSU calculator at http://www.houseofmobos.com under power supplys to see if you have enough power. Link to comment Share on other sites More sharing options...
Rhumba Posted October 6, 2005 Author Share Posted October 6, 2005 According to the calculator, I'm not even at 300 watts. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 7, 2005 Corsair Employee Share Posted October 7, 2005 I think you may be missing something. According to what you have listed you would need about 350-380 Watts max continious power. Link to comment Share on other sites More sharing options...
Rhumba Posted October 15, 2005 Author Share Posted October 15, 2005 I finally had a chance to throw this memory into the P4P800 and the board would not boot. Do I need to do anything to get it to boot on that board? That board currently has pc3200 ram in it, but its 2x512. Link to comment Share on other sites More sharing options...
Garvin Posted October 15, 2005 Share Posted October 15, 2005 Notes: 1.The Invidea firewall is a bit picky about being setup correctly but runs fine on my system with medium settings, high tends to fubar ftp downloads. 2. Your running close to full steam on that Antec supply, especially on an nf4 based board, and it is probably the source of your memory problems. 3. A useful link for this board (A8n-sli dlx), including bios settings on the first page: http://hardwareanalysis.com/content/topic/38623/ Link to comment Share on other sites More sharing options...
Rhumba Posted October 17, 2005 Author Share Posted October 17, 2005 1) I don't have the Nvidia firewall installed. Tried it both with and without. 2) I checked out the mobo check page and it did not show me close to the max yet. EDIT: I just ran this through again. I'm coming in right around 300. Why do you think it would be more than that? 3) I've looked through that page. Tried using all the bios settings on that page and it did not help. Even at 333mhz I'm still hard locking up occasionally. I'm really beginning to think that I just got some bumm memory. From what I see, the P4P800 should have been able to at least post with this memory. And that has a larger power supply on it. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 17, 2005 Corsair Employee Share Posted October 17, 2005 Did you reset your bios when you changed the modules? if so let's get them both replaced. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! Link to comment Share on other sites More sharing options...
Rhumba Posted October 26, 2005 Author Share Posted October 26, 2005 Was out of town for a few days. I did one more test and am more convinced its the memory. I pulled the memory from my other pc and put it into the new one. It is Corsair CMX512-3200c2 memory and its a twinx pair. I set it to 2.75v 2.5-3-3-6 1t. 400mhz. I'm having no issues with that memory. I've run many downloads and they've not been corrupted. I also ran everquest pretty heavily for about an hour pretty heavy and have not had any lockups. I'm just not sure what else to try with this new memory. Nothing I try seems to help. Memtest comes up clean, but downloads are corrupted at 400mhz no matter what settings i use, and even at 333mhz i lock up occasionally in everquest.

Rhumba Posted October 26, 2005 Author Share Posted October 26, 2005 Another question I have now. Since this new system works great with this old memory. Is it enough to rule out the psu? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 26, 2005 Corsair Employee Share Posted October 26, 2005 Yes the PSU may or may not be the issue, but based on your config I would suggest you consider a newer bigger unit ASAP.

Rhumba Posted October 26, 2005 Author Share Posted October 26, 2005 So then the two types of memory I tried use differing amounts of voltage? I plan to get it replaced, but am still very much a novice at the psu side of things. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 26, 2005 Corsair Employee Share Posted October 26, 2005 Sorry but I dont understand your question! Link to comment Share on other sites More sharing options...
Rhumba Posted October 26, 2005 Author Share Posted October 26, 2005 I tested the memory from my old pc, which I listed above at the same voltage as my new ram. The old ram is working great and I'm having no issues with it. I'm curious as to why the PSU would be an issue with the new memory but not the old, since with the old I'm running great at 400mhz. Does the old memory just take less power? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 26, 2005 Corsair Employee Share Posted October 26, 2005 The PSU is another issue, and you are welcome to keep what you have but as I said I think you will eventually have problems. What is the part# of the old memory? Link to comment Share on other sites More sharing options...
Rhumba Posted October 26, 2005 Author Share Posted October 26, 2005 CMX512-3200C2 is the old memory that's working great in the new box. Link to comment Share on other sites More sharing options...
Ulvster Posted October 27, 2005 Share Posted October 27, 2005 I have the exact same problems with two sets of TWINX2048-3200C2, one is used in a MSI NEO4 (NON SLI)mb with an Athlon X2-4400, and the other is used in an Asus A8N-SLI board with an Athlon X2-3800. Both are fairly stable at stock speed at 2,75v with 2.5-3-3-6-1t timings - but they dont like high fsb at all - anything over 210fsb is unstable, they go to about 220 with loose timings in 2t mode.... Both mb's has the latest bios (1.9 for the MSI and 1012 for the Asus), the psu is a Fortron/Source 550w. I thougt these chips were supposed to be high performance chips suitable for overclocking - even my old pair of 2x512 XXXXXXX cheapo ram goes higher with tighter timings! Must be some problems with NForce4/Athlon X2? Link to comment Share on other sites More sharing options...
Rhumba Posted October 27, 2005 Author Share Posted October 27, 2005 I'm not even trying to overclock. I can't run stable at 2,75v with 2.5-3-3-6-1t timings at 400mhz. Even running at 210 and below. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 27, 2005 Corsair Employee Share Posted October 27, 2005 Ulvster These new CPU's seem to be the limiting factor, but I would test the system one module at a time and set the timings to By SPD and set the voltage to 2.8 Volts and see what you can get. But remember you may have to set the HTT Freq at 3 or 4 as well as set or lock the PCI/AGP freq. some MB's do better at this than others. Rhumba, Let's get the modules replaced.
