adipate Posted December 30, 2007 Share Posted December 30, 2007 I have an ASUS P5K-E, TWIN2X2048-8500C5 (2x1GB), Intel E6750 (2.66Ghz). I'm having trouble getting this ram up to speed. Initially I couldn't even get memtest to run and the system would lock up. memtest 1.7 wouldnt run and 1.65 would have a panic and dump. Eventually I got it set to 800Mhz and it ran fine at 800 and passed ~4 passes in memtest, but still can't get it to run at 1066. I have tried manually setting the timings and speed, this results in it locking up. I've also tried the following settings: AI Overclocking: Manual CPU Ratio Control: Auto FSB Frequency: 333 PCI-E Frequency: 100 DRAM Command Rate: 2T DRAM Frequency: 1066 FSB Strap to Northbridge: 333 DRAM Timing Control: Manual CAS# Latency: 5 RAS# to CAS# Delay: 5 RAS# Precharge: 5 RAS# Activate to Precharge: 15 TWR: Auto TRFC: Auto TWTR: Auto TRRD: Auto TRTP: Auto DRAM Static Read Control: Disabled Transaction Booster: Auto Clock Over-Charging Mode: Auto CPU Spread Spectrum: Enabled PCIE Spread Spectrum:Enabled CPU Voltage: Auto CPU Voltage Reference: Auto CPU Voltage Damper: Enabled CPU PLL Voltage: Auto DRAM Voltage: 2.2v (For V1.xx) or 2.1v (for V2.xx) FSB Termination Voltage: Auto North Bridge Voltage: 1.4 North Bridge Voltage Reference: Auto South Bridge Voltage: Auto Transaction Booster: Auto Advanced CPU Settings CPU Ratio Control: Auto C1E Suppport: Enabled Max CPUID Value Limit: Disabled Vanderpool Technology: Enabled CPU TM Function: Disabled Execute Disable Bit: Enabled PECI: Disabled With 2.2v on the ram it ran for 5m37s in memtest and locked up. With 2.1v I've gotten some errors (3 passes have completed and its currently on pass #4 Test #4): Test Pass Failing Address Good Bad Err-Bits Count Chan 6 1 [00000000000 - 0.0MB] 00000004 00000000 00000004 1 7 1 [00000000000 - 0.0MB] 46c85415 00000000 46c85415 1 7 2 [00000000000 - 0.0MB] f8bae9e7 00000000 f8bae9e7 1 Is this ram bad? Should I obtain an RMA? Am I doing something wrong? :[pouts: (Complete system specs are in my profile) Update: I clocked it back to 800 and ran memtest: Test Pass Failing Address Good Bad Err-Bits Count Chan 6 2 [00000000000 - 0.0MB] ffffffbf 00000000 ffffffbf 1 7 2 [00000000000 - 0.0MB] a7ade37d 00000000 a7ade37d 1 Link to comment Share on other sites More sharing options...
Inti619 Posted December 30, 2007 Share Posted December 30, 2007 I am having problems as well with the same ram and MOBO. I have no idea whats going on and this after I just recieved a faulty EVGA A1 which blew up 1 of each of my pairs of old memory (Dominators as well) on first boot and 2and OCZ. Run to the store buy this memory and this mobo and have spent the last 8 hours playing around with settings ranging from voltages to speed to auto. I am completely bewildered. Windows will install but games and some installs and patches all do not work. I am stunned at the problems I have encountered with this mobo and ram it seems. If anyone can help solve this stability problem please help. System specs are in my info. Link to comment Share on other sites More sharing options...
adipate Posted December 30, 2007 Author Share Posted December 30, 2007 Update: I clocked it back to 800 and ran memtest: Quote: Test Pass Failing Address Good Bad Err-Bits Count Chan 6 2 [00000000000 - 0.0MB] ffffffbf 00000000 ffffffbf 1 7 2 [00000000000 - 0.0MB] a7ade37d 00000000 a7ade37d 1 Well I let it run through the night and it ran some 22 passes or so and those were the only errors :confused:. It was stable at 800Mhz and I played bioshock almost all night the other day but I'd really like to get this ram and MB running to spec. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 31, 2007 Corsair Employees Share Posted December 31, 2007 Please make sure that you have the latest Bios version and then load setup/optimized defaults and set the Dim Voltage to 2.1 volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/'s one at a time with http://www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
adipate Posted January 1, 2008 Author Share Posted January 1, 2008 I'm always reluctant to do BIOS upgrades and flash firmwares but the other day I flashed the motherboard from 0703 to 0901. I then tested teach stick at these settings: AI Overclocking: Manual CPU Ratio Control: Auto FSB Frequency: 333 PCI-E Frequency: 100 DRAM Command Rate: 2T DRAM Frequency: 1066 FSB Strap to Northbridge: 333 DRAM Timing Control: Manual CAS# Latency: 5 RAS# to CAS# Delay: 5 RAS# Precharge: 5 RAS# Activate to Precharge: 15 TWR: Auto TRFC: Auto TWTR: Auto TRRD: Auto TRTP: Auto DRAM Static Read Control: Disabled Transaction Booster: Auto Clock Over-Charging Mode: Auto CPU Spread Spectrum: Enabled PCIE Spread Spectrum:Enabled CPU Voltage: Auto CPU Voltage Reference: Auto CPU Voltage Damper: Enabled CPU PLL Voltage: Auto DRAM Voltage: 2.1v FSB Termination Voltage: Auto North Bridge Voltage: Auto North Bridge Voltage Reference: Auto South Bridge Voltage: Auto Transaction Booster: Auto Advanced CPU Settings CPU Ratio Control: Auto C1E Support: Enabled Max CPUID Value Limit: Disabled Vanderpool Technology: Enabled CPU TM Function: Disabled Execute Disable Bit: Enabled PECI: Disabled I did 12 passes with each stick (without any errors) and then before I went to bed I put both back and and left it to run. It had completed some 30 passes or so without any errors. I believe it's all dialed in and stable. I'll give another follow up in a week or so when I get my other HD back and put windows back on it. :headbang: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 2, 2008 Corsair Employees Share Posted January 2, 2008 The memory voltage should be 2.1 Volts but if it's stable then let it run. Link to comment Share on other sites More sharing options...
adipate Posted January 19, 2008 Author Share Posted January 19, 2008 Well it's been a couple of weeks but the system is stable at 1066 (running at the settings I posted above, 2.1v). It is my assumption that the bios update solved the issue. I just figured I'd come back and give some feedback for other people searching the forum, etc. Link to comment Share on other sites More sharing options...

goodole1 Posted August 5, 2008 Share Posted August 5, 2008 Well, looks like I opened Pandora's Box so to speak. I recently lost my Asus P5P800 SE mobo and after reading a thousand reviews it turns out that the Asus P5K-E board had the less cursing about it. I intend on using the Intel Q9450 CPU and a Evga 8800 GT (don't need high end stuff here, no gaming) Sooo, since I've had some problems in the past with ******** I decided to try Corsair memory. Now the fiasco starts, it seems no matter what mobo manufacturer you use they all have one thing in common. MEMORY instabilities. After reading many post here it would appear that my original choice of memory TWIN2X2048-C5 may not be the wise choice as most controllers won't allow the 1066 range without dancing through hoops to accomplish it and at best it may or may not run. This kinda sucks because I would like to get what I paid for. I want to put in memory sticks that will at least get me close to the mobo specs without all the darn headaches and now I'm stumped. Since I'm reading about how much trouble the mobo is causing with the 8500 C5's, how much would I lose if I try to use the TWIN2X2048-6400C4 and can I run it without the problems reported with the 8500 C5's? Building computers used to be fun, not anymore! Regards Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 5, 2008 Corsair Employees Share Posted August 5, 2008 I think you are making some assumptions that may not be correct, how many people do you see having problems? And if you think that is everyone you are mistaken we sell literally hundreds of thousands of sets of these modules so most more then 90% never have a problem and most of the users who post here get their modules working once they set the proper settings and or update the MB and set the tested settings. Please make sure that you have the latest Bios version and then load setup/optimized defaults and set the Dim Voltage to 2.0 volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, or if you have Value Select "BY SPD" and then test the module/'s one at a time with http://www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.

goodole1 Posted August 5, 2008 Share Posted August 5, 2008 I would like to believe that Corsair makes a better chip then ******** who has had quite a few problems. The assumption is because of reviews of the P5K-E board when they have tried not just Corsairs 8500's but others as well. So maybe I didn't convey that part properly. I really would liketo achieve a 1066 FSB if possible. Currently I'm waiting for the Video board which should be here tomorrow and I do have a set of ********s on hand to try to start the system up with to make sure the board is functional as well as the CPU. Since I've had problems in the past with ******** I really don't want to stick with them. One more thing, my assumption that the Corsair 8500 and 6400 are low density module is correct?

Corsair Employees RAM GUY Posted August 5, 2008 Corsair Employees Share Posted August 5, 2008 The term "low density" would be a relative term in that it would be relative to the chipset you are using but no they would be considered high density ATM but early version may have been a lower density.
