kmuel Posted February 4, 2005 Share Posted February 4, 2005 I have 4 sticks of 256M RAM and want to ppopulate all 4 dimms slots. I have it running with dual memory. When I put the other 2 sticks in, I get no boot. All modules are identical. I have tested all the memory. ASUS tech support says that I need to set the memory timings manually to get all 4 running. There may be errors setting the BIOS to "auto" I don't know what settings to change. There are about 8 different memory settings. I know my memory should be set at 2,3,2,6. What about the other BIOS memory settings. Can you help me configure this BIOS? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 4, 2005 Corsair Employee Share Posted February 4, 2005 If the system will post with all four installed, please go to bios setup and load setup defaults and then set the following settings. Dim Voltage to +2.7 Volts: CAS Latency CL=2.0 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 3 Row to Row delay Bios Default Min Ras# Active Time tRAS 6 Row Precharge Time tRP 2 Write Recovery Time Bios Default Write to Read delay Bios Default Read to Write Delay Bios Default Refresh Period tREF Bios Default Enable 2T Timing Enabled Then test the system with http://www.memtest.org and make sure it's stable!

kmuel Posted February 4, 2005 Author Share Posted February 4, 2005 The problem is that it won't post with 4. It will post with 2 in dual channel. I'll try these settings. Link to comment Share on other sites More sharing options...
kmuel Posted February 5, 2005 Author Share Posted February 5, 2005 This is a "no go". I booted into the BIOS and changed these settings. Then installed the other two memory modules. The result was no boot. Any ideas. I bought this board with the idea that I would be able to populate all 4 slots with matching Corsair memory. Thanks Link to comment Share on other sites More sharing options...
Wired Posted February 5, 2005 Share Posted February 5, 2005 Try looser timings: CAS Latency: 3 RAS to CAS Delay (tRCD): 4 Row Precharge (tRP): 4 Active to Precharge Delay (tRAS): 8 Link to comment Share on other sites More sharing options...
kmuel Posted February 5, 2005 Author Share Posted February 5, 2005 I tried this and then even with two sticks that had been running, the computer wouldn't boot. The computer is now running with the orig. 2 sticks of memory. Here's how I feel after purchasing this expensive Corsair memory: This seems to be a major problem with this baord. The advertise that you can populate all 4 slots with identical ram. Called Asus - They said call Corsair, even though there are numerous reports of problems when populatins all four dimm slots Called Corsair - They don't have much tech support for this particular board.

kmuel Posted February 5, 2005 Author Share Posted February 5, 2005 Here are my current setting - works with 2 sticks dual channel. Ready to try the other 2 sticks - any suggestions? Changes - SET BURST LENGTH TO 4 from 8 Dim Voltage to +2.7 Volts: CAS Latency CL=2.0 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 2 Row to Row delay Bios Default Min Ras# Active Time tRAS 6 Row Precharge Time tRP 2 Write Recovery Time Bios Default Write to Read delay Bios Default Read to Write Delay Bios Default Refresh Period tREF Bios Default Enable 2T Timing Auto Link to comment Share on other sites More sharing options...
Wired Posted February 5, 2005 Share Posted February 5, 2005 tRCD should be 3. What revision is each stick? How To Read the Memory Label Also, what do you mean by Corsair not having much tech support for that board? Link to comment Share on other sites More sharing options...
kmuel Posted February 5, 2005 Author Share Posted February 5, 2005 Well Corsair doesen't have any phone support or e-mail contacts that I could find on their customer support link. I did find that one of my modules has a different version. 3 are 1.1 and 1 is 2.1. I'm acting on the belief right now that this is the problem. That even the exact same modules might have different versions? I had no idea this would be an issue. I've used mixed versions in my previous three Asus boards. This is my first A8V. It's tough when you buy a module online to know what you're getting in terms of it's version. I still think that with just the right settings, these modules could work. I've also discovered that running memory in four banks is a tricky task. Anyway, I'll try to RMA the memnory and start over again. A finicky board indeed.

Wired Posted February 6, 2005 Share Posted February 6, 2005 They have both phone #s and email addresses. http://compatible.corsairmemory.com/corsair/warranty.html The link SHOULD be http://www.corsairmemory.com/corsair/warranty.html but I think they're updating the site or something atm, either that or someone messed up lol. Just in case the links don't work when you read this: warranty@corsairmemory.com rma@corsairmemory.com ramguy@corsairmemory.com 1-888-222-4346 There's a customer service email address I think, can't remember it offhand.

leeghoofd Posted February 6, 2005 Share Posted February 6, 2005 Did you try PC2700 settings or PC333 ? AMD VIA based boards are very itchie regarding the amount of ram. If this doesn't work it's better to try to get 2x512 sticks, I still don't see the point of populating the 4 banks , I read it many times even on Intel mobo's that the risk of error is way higher than with 2 sticks. You like to live dangerously Kmuel ? Also look at http://www.abxzone.com and look into the AMD64 VIA based section , try to grab hold of lady Sierra she's the A8V high tech guru there Link to comment Share on other sites More sharing options...
Wired Posted February 6, 2005 Share Posted February 6, 2005 I think I'll go poke around there for more A8V stuff, thanks for the tip! Link to comment Share on other sites More sharing options...

kmuel Posted February 6, 2005 Author Share Posted February 6, 2005 Thanks leeghoofd for the info. Basically I'm cheap. I had 3 256 M sticks of good Corsair ram which I took out of my last build. Since I was selling that rig, I replaced the Corsair with some 2700 Samsung. Anyway, I thought that if I bought 1 more stick, I could get 1G of ram running in my A8V. So, I bought a stick for 85.00. Now I have like 300.00 invested in this RAM. It's good RAM, but I can't seem to use all of it. I did not read about these issues before making my purchase The two sticks currently in the machine are running at 220 = 2415. I know they will go further, but hey, I'm not greedy. I did set the BIOS to AUTO everything except the memory settings when I tried all 4 sticks. Isn't this the normal system speed? (333) Are you suggesting that I "underclock" the rig? If so, this begs the question of; is it better to get a good overclock with 500M of Ram or underclock and get 1G. Link to comment Share on other sites More sharing options...
