dXsL Posted March 25, 2008 Share Posted March 25, 2008 setup: asus P5K, intel E6850, corsair TWIN2X2048-8500C5D, asus 8800gts640, corsair 750W psu modules are running flawlessly at SPD (DDR2-800, pc-6400 specs) but no POST at 1066 (using 5-5-5-15-2T 2.2V, latest p5K bios, no overclocking) tried many, many, many tips/tricks etc found online.... :bigeyes: so please RAM guy :), is it possible to run these modules on a p5K or not? (I found contradictory statements about this online...:confused:) tnx! Link to comment Share on other sites More sharing options...
DerekT Posted March 25, 2008 Share Posted March 25, 2008 I have run 8500C5 on almost every iteration of P5K boards. There is no issue. So let's see what's wrong.Download memtest from--->Here and extract the ISO image. Burn the ISO image to an CD-ROM disk.Enter your BIOS. Load setup defaults, save setup defaults and set to these values:AI Overclocking: Manual CPU Ratio Control: 9 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 version 1.xx) or 2.1v (for version 2.xx+) FSB Termination Voltage: Auto North Bridge Voltage: 1.4 North Bridge Voltage Reference: Auto South Bridge Voltage: Auto Transaction Booster: AutoAdvance CPU SettingsCPU Ratio Control: Auto C1E Suppport: Enabled Max CPUID Value Limit: Disabled Vanderpool Technology: Enabled CPU TM Function: Disabled Execute Disable Bit: Disabled PECI: Disabled Shut the system down. Boot to the Memtest CD. Allow for two full passes unless errors occur. If errors occur. Remove one stick of DRAM. Leave the first stick (Closest to the CPU) in and boot to the Memtest CD. Allow for two full passes. Remove and replace with the second stick. Retest. If the sticks pass, then test with a single stick in the second slot, then third slot, and finally fourth slot.

Morichi Posted March 25, 2008 Share Posted March 25, 2008 hi there sorry for the las post, but my keyboard fall down and the Enter key was press. With this config can I fix the post problem? thx and sorry again Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 25, 2008 Corsair Employees Share Posted March 25, 2008 I would test the modules one at a time to make sure that one is not failing or if there is some other problem. Link to comment Share on other sites More sharing options...
dXsL Posted March 25, 2008 Author Share Posted March 25, 2008 (lost all i was typing so i'll try again :o:) hi and thanks for the extensive help! first I fixed the "no post" problem using this workaround: http://www.tomshardware.co.uk/forum/246388-12-deluxe-wont-post-workaround (removed both corsair memory modules, insert samsung pc5300 single module closest to cpu, post ok, enter bios, change DIMM speed from AUTO to DDR800 (or DDR667), removed samsung module, insert single corsair pc8500 module, post ok, insert second corsair pc8500 module, post ok, boot with memtest86+ 2.01, ran 2 passes: 0 faults so memory is ok at DDR800 (SPD setting) then I entered all settings from DerekT, except the ones below: *** CPU Spread Spectrum: Enabled -> left on AUTO, no ENABLE in list, only AUTO AND DISABLE...?? *** PCIE Spread Spectrum:Enabled -> left on AUTO, no ENABLE in list, only AUTO/DISABLE...?? *** PECI: Disabled -> parameter not found under advanced cpu setting...??? after reboot: no POST :roll::roll::roll: so I can't get in the bios to change things, I have to start at at the beginning again to solve the "no post" problem :(: any suggestions/additions to your bios settings that might work? I wanted to test the memory at 1066 but without a POST that will be difficult :p: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 25, 2008 Corsair Employees Share Posted March 25, 2008 I would try and clear the BIOS and see if it will post with just one module installed and if so you should get the latest BIOS installed and then load setup defaults and set the memory Voltage to 2.1 Volts.

dXsL Posted March 25, 2008 Author Share Posted March 25, 2008 I lied... :eek: :laughing: I did not have the last bios version (thought I had...) Asus released a new bios a few weeks ago: version 1005. According to them to "Enhance compatibility with certain memory module.":roll: Also, corsair memory is version 2.3, and runs according to the label at 2.15V (not 2.1V or 2.2V - but 2.2V which I tried should still be ok hmmm...) @ram guy: i'll now try to run a single module @1066 after I have flashed the bios to v1005, and then run a memtest, insert second, etc...

Corsair Employees RAM GUY Posted March 25, 2008 Corsair Employees Share Posted March 25, 2008 NP Please let us know, but that BIOS should correct the no post issue. Link to comment Share on other sites More sharing options...
dXsL Posted March 26, 2008 Author Share Posted March 26, 2008 it works! :biggrin::biggrin: After weeks of experimenting, giving up and starting again several times it finally works. Thanks to settings provided by DerekT and the Asus P5K 1005 bios posted March2008. Thanks RAM guy and DerekT for prompt response. great, guys! The memory runs rock solid at 1066, I ran 2 passes of memtest86+, no problems whatsoever. [offtopic] Now that I know that the memory is stable, I could start to play... My E6850 runs fine at 3.6 with 400fsb, 1:1 ratio and thus memory at spd spec again :laughing: My original goal was because of the 5:6 ratio to run fsb at 444, thus memory at 533 (1066). That's why I bought the Dominator in the first place ;): Now I can finally search for the limit, both in fsb (with stock cpu cooler...), and the corsair memory (without memory fans).

Corsair Employees RAM GUY Posted March 26, 2008 Corsair Employees Share Posted March 26, 2008 I doubt that will work out that way, from what I have seen when the CPU FSB gets much over 333 MHz the memory frequency will have to be more insync with the CPU but with the newer chipsets they might be able to run the divider settings a bit better so just try it and see.

jere39 Posted April 13, 2008 Share Posted April 13, 2008 P5K TWIN2X2048-8500C5D (2.2V ver4.1) E8200 Hi guys, please excuse my english, I'm french ;): I bought this MB one week ago, with the E8200 and Corsair memory. I had no post, so after reading forums, I bought a Kingston 512Mb PC5300, and the POST is always ok with this memory. Please notice I've NEVER had POST ok with Corsair memory I've tested many differents BIOS setups, with 0902 and 1005 versions, put single memory and dual in both yellow and black slots, cleared CMOS each time I've flashed the BIOS.... I'm not a beginner, but this time I need help, because I bought 2Gb@1066Mhz and the only way for me to hear a beep is to put 512Mb@667Mhz :(: Can someone tell me which BIOS to use and every settings I have to put, because when I read this topic, I see people who have successfully installed this Corsair Memory... Thank you guys, have a nice day ! Jerem Link to comment Share on other sites More sharing options...
