twoodster Posted February 16, 2006 Share Posted February 16, 2006 Hi I'm running 4 sticks of VS512MB400C3 in an Asus A8N-Sli Deluxe. My processor is an AMD 3500XP. Problem is, I cant seem to run the ram at anything more than 200mhz - is it not possible? I seem to get random blue screens etc when trying anything higher. I play a lot of games, and the performance at the moment isn't great - runs great when switching to 400mhz :( Thanks in advance Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 16, 2006 Corsair Employee Share Posted February 16, 2006 Can you tell me the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? As well as the complete system configuration including the make and model of your PSU? Link to comment Share on other sites More sharing options...
twoodster Posted February 16, 2006 Author Share Posted February 16, 2006 Cpu Core Speed is 2211.3mhz Memory Settings: CAS#Latency 2.5 RAS# to CAS# Delay 3 RAS# Precharge 3 Cycle Time (Tras) 7 Bank Cycle Time (trc) 10 I've tried multiple recommended configurations for the above though, and it doesn't seem to make a great deal of difference in regard to the blue screens. All the other settings (including CPU) are running at default. The PSU is a HEC-550TD-PTE 550W. Where abouts do I find the FSB? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 16, 2006 Corsair Employee Share Posted February 16, 2006 Please try these settings and test the modules one at a time with http://www.memtest.org Memory Settings: Dram Voltage 2.7 Volts CAS#Latency 3 RAS# to CAS# Delay 3 RAS# Precharge 3 Cycle Time (Tras) 8 Bank Cycle Time (trc) 14 Link to comment Share on other sites More sharing options...
twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 Thanks - what speed for the ram though? Link to comment Share on other sites More sharing options...

Second, you cannot run any memory above 200MHz (DDR400) on any Athlon 64 motherboard without overclocking your CPU's HTT clockspeed. Third, you have all four memory slots filled with double-sided (double-rank) DIMM's. That will seriously limit your overclocking performance, and may also drop your memory speed below your processor's HTT clockspeed. As such, you may be running your memory at DDR400 - but (obviously) you had to use a 2T command rate setting just to run stably. There is simply excessive loading on your CPU's memory controller when you run four double-sided sticks of memory. Your best bet, in this case, is to replace all four of your 512MB sticks with two 1GB sticks. (In other words, get a VS2GBKIT400C3 kit - or better yet, a TWINX2048-3200C2 kit - and find other uses for your four existing 512MB sticks.)

twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 Ah right, thanks. Can't really afford to replace what I have right now though. What would you suggest as the optimal settings for my current setup? Also, I have a stick of Hynix 512 DDR 400 CL3. Am I likely to get better performance using that with a stick or two of the Corsair instead? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 17, 2006 Corsair Employee Share Posted February 17, 2006 With 2 modules that are matched you should be able to run at DDR400. However, if you install 4 modules with this CPU and MB you may need to run the memory at DDR333 and I would set the memory voltage at 2.8 volts.

twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 Hmmm, now I'm confused ;) The chap above says I can't run anything higher than 200mhz with an Athlon 64? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 17, 2006 Corsair Employee Share Posted February 17, 2006 With Double Data Rate 200 Mhz Clock Frequency = DDR400! Link to comment Share on other sites More sharing options...
twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 Ah right, but I can only run at DDR400 with two sticks? So what settings do I need to run four sticks at DDR333? Sorry to ask so many questions! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 17, 2006 Corsair Employee Share Posted February 17, 2006 Just set the timings to By SPD and the MB will set the timings for you. Link to comment Share on other sites More sharing options...
twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 I don't appear to have a 'By SPD' option. All I can do is set the timings and ram speed etc manually, or select 'Automatic' and then it does everything itself. Problem is, the Automatic option selects 333mhz speed and therefore causes blue screens. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 17, 2006 Corsair Employee Share Posted February 17, 2006 Just leave them set to AUTO that will set the timings to BY SPD. Link to comment Share on other sites More sharing options...
twoodster Posted February 17, 2006 Author Share Posted February 17, 2006 The Auto option causes the blue screening though. That's why I've been trying to set things manually in the first place. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 17, 2006 Corsair Employee Share Posted February 17, 2006 Please test the modules one at a time with http://www.memtest.org and go to the bios setup and load setup defaults and then set the memory voltage to 2.7 Volts and exit saving changes should be all you need to do.

twoodster Posted February 18, 2006 Author Share Posted February 18, 2006 Well, each stick of ram tests out fine - and it still blue screens using default bios settings. Only way to stop the crashing is setting the ram to 200mhz manually, but that causes crappy performance in games. Guess I'm just going to have to replace it :[pouts: Link to comment Share on other sites More sharing options...
twoodster Posted February 20, 2006 Author Share Posted February 20, 2006 Right - I've decided I'm going to have to get some more ram as I can't be coping with the constant blue screening! What is the best option? I play a lot of games, so need the fastest type possible. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 20, 2006 Corsair Employee Share Posted February 20, 2006 Can you tell me the stop error code you get? And have you installed the AMD CPU driver? Link to comment Share on other sites More sharing options...
twoodster Posted February 21, 2006 Author Share Posted February 21, 2006 The Stop Code seems to be different each time. Here's a couple of examples though: STOP: 0x0000000A (0x00010000, 0x0000001C, 0x00000001, 0x80502000) STOP: 0x00000050 (0xAB1D61FA, 0x00000001, 0x8054AAZE, 0x00000000) I've not installed the AMD Cpu driver - the only thing I've attempted is to upgrade the bios, and that didn't make any difference. Thanks Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 21, 2006 Corsair Employee Share Posted February 21, 2006 That looks to be a driver issue, you can search for the stop error at http://www.microsoft.com/technet and this is the one that comes up. Also have you installed the NVidia IDE driver? If so I would try and uninstall it. Link to comment Share on other sites More sharing options...
twoodster Posted February 23, 2006 Author Share Posted February 23, 2006 Well, I formatted my computer yesterday to see if it would sort the problem at all. Lasted 24hours, then I switched it on this morning and the computer wouldn't boot. Back to 200mhz in the bios and it's working ok again. So, it's definately looking like I need some more ram! Any suggestions? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 23, 2006 Corsair Employee Share Posted February 23, 2006 Are you running 4 modules? If so what are the settings you are trying to run them at? And if you change memory I would go with 2 1.0 Gig modules for best performance. Link to comment Share on other sites More sharing options...
twoodster Posted February 23, 2006 Author Share Posted February 23, 2006 I've tried every setting under the sun!! The only way to get the four sticks stable is to set the speed to 200mhz, and then games etc run really slow. Would you recommend something like this? http://www.ebuyer.com/customer/products/index.html?rb=16486467933&action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=66393 I need the best performance possible really. Thanks Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 23, 2006 Corsair Employee Share Posted February 23, 2006 With 4 modules you should have the memory at DDR333. And I would suggest Twinx2048-3200C2 for a bit better performance but yes those module will run in your system. Link to comment Share on other sites More sharing options...
