Kingpinda Posted February 11, 2008 Share Posted February 11, 2008 Hi there, I'm having a bit of problems with these modules in my system. They won't run at stock speed (DDR1066). Presumably it has to be with my motherboard which may not set automatic settings correctly. I have put in the cas timings 5-5-5-15-5-2T manually and manually increased voltage to 2.1 and 2.2 respectively. However the other timings may not be set correctly. I'll download memset later on to verify where my Mobo put them and may list them to verify with you if these are correct. Also i have read putting the NB SPP voltage up by 0.05 over default. Will try that also. However! hehe I've still got a lingering question.. I've read in the Dominator Qualifications and Testing thread that you have tested this module: DDR2 SDRAM Clock: Manually set to 800MHz By this do you mean DDR800 or DDR1600? And if this is DDR800 why isn't it tested then at DDR1066 since the module is sold like this? Only started out using DDR2 this year. All my experience in memory is with DDR1 so it could be that my thinking is a bit faulty. Hoping for a swift reply :) Thanks! Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted February 11, 2008 Corsair Employees Share Posted February 11, 2008 Please make sure that you have the latest BIOS for your motherboard and then load optimized defaults and set the Memory Voltage to 2.1 volts and then set the timings to 5-5-5-15 (CAS-tRCD-tRP-tRAS) and frequency to 1066MHz. Configure these settings in the BIOS and then test the modules one at a time with http://www.memtest.org! Please allow memtest to run 2-3 passes on each module. If you still get errors, we will be happy to replace them! 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 the XMS Qualifications and Testing thread, the board used to originally to test the board used was the ASUS M2N32-SLI Deluxe. With this board you would have to set memory frequency to 800MHz (there is no 1066MHz option) and then overclock the FSB of the CPU in order to get the memory running at 1066MHz. With your motherboard you have the option to set the memory to 1066MHz and you do not need to overclock the CPU in order to run the memory at its tested settings.

Kingpinda Posted February 11, 2008 Author Share Posted February 11, 2008 Thanks, i will try testing each module tommorow. Thought i may had found the problem.. Looks like my mobo undervolts. I had to up the dram voltage to 2.7 to have it show 2.22 in everest. Anywhere below this voltage at 1066 mhz it would freeze either my bios or memtest. Finally with voltage at 2.7 (everest volt2.22) It would RUN Memtest. Got the mega errors in test 5 and 7. This rang a bell which led me to believe its a setting problem. Had this kind of problems with ddr1 in combination with dfi as well. Although i there just had to change the auto settings in the correct ones. Upped the NB V by 0,05 and thought the errors decreased. But stuck now. No matter what i change errors aplenty. relaxed timings... nada.. oh well.. more testing tommorow.

Corsair Employees RAM GUY Posted February 12, 2008 Corsair Employees Share Posted February 12, 2008 You may want to contact your motherboard manufacturer regarding this issue. I could not recommend setting the memory voltage to 2.7v unless you have measured the voltage with a volt meter. Software readings are fairly unreliable most of the time and can be off by quite a bit. Regardless if your board indeed needs to be set to 2.7v in order to get the memory up to 2.2v then the board may need to be replaced. Link to comment Share on other sites More sharing options...
Kingpinda Posted February 12, 2008 Author Share Posted February 12, 2008 Yes gonna contact DFI right away. Running stable ddr800 now by putting bios voltage to 1.9. Everest says 1.82. Strange thing however... Whenever i start prime95, voltage drops to 1.81... so most likely a problem there. Furthermore i have a question regarding warranty. Most likely this will not apply to me since i bought these modules from another end-user. Correct? I haven't tested each individuel module yet because i thought i isolated the problem and well.. hehe its tedious taking them out. If i have no claim on warranty i'll just cope and try and get the utmost out of ddr800 and maybe i'll be able to pull a bit more juice out of them for a +400 fsb overclock. BUT PRAY if I am entitled on warranty i'll test them anyway you want me too :) Just contacted DFI. They advised me to get the latest BETA bios since this adresses some issues with NB and 45nm technology. Will try that in a moment. Furthermore they asked if i contacted you guys from corsair and afterwards that in some cases for modules more juice is required. They advised me that if my modules run better on higher voltage then go with it. Could be a problem with the e8400 also they told me hence the beta bios update. But unfortunately i do not have a 65nm c2d to test with. I'll start testing with nominal voltages after flashing my bios and see what happens. then slowly upping voltages from NB and dimm. I'll let you know what i come up with. Oh btw.. when will you guys come up with temp diodes on mem modules? :) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 12, 2008 Corsair Employees Share Posted February 12, 2008 Here is a link to our Warranty Information, you may need to get the seller to RMA the modules for you. Before an RMA, I would recommend testing the modules in a different system to make sure that the problem is not with the motherboard, and see if you can isolate a faulty module. As for the temp diodes, unfortunately I am unaware of any plans to include them on our modules. Link to comment Share on other sites More sharing options...
Kingpinda Posted February 23, 2008 Author Share Posted February 23, 2008 Thanks for the feedback. After some tedious testing i've located the problem... Using the 333/1066 divider with default settings and voltage at 2.2 creates thousands of errors. However i've been testing my processor and got it stable at fsb 444. After applying the 333/800 divider i came up with ddr1066. which on voltage settings of 2.2 performs flawless... So my motherboard is the issue.. it doesnt run at 333/1066 but it does run at 333/800 with fsb up to 444... Took me a while but now i'm happy :) ta!

DerekT Posted February 24, 2008 Share Posted February 24, 2008 So, you are running at ~4.0GHz? Those 8400's sure are nice. :D: The 333/1066 Board anomaly is certainly strange. I have found with older boards (i965) that 400Mhz was a sweet spot and performed with more stability than 333. Tweaking is half the fun, extracting the performance is the other half. What cooling do you have on the CPU. Idle and Load temps? Voltages? Inquiring minds want to know :D: Link to comment Share on other sites More sharing options...
Kingpinda Posted February 25, 2008 Author Share Posted February 25, 2008 yep got it running @ 4ghz. Using a thermalright 120 extreme with a scythe 1600 rpm fan. @stock speed it ran at idle:18c went to 16 after 2 weeks because of arctic silver 5, load:30 i think.. forgot ;) maybe in the twenties. @4g's voltage 1.4v idle:29 load:44 I think i can tweak the voltage down somewhat however. just did a quick test over the weekend during a lanparty. and the few hours i slept it was priming. cpu ran flawless at 3600 with default cpu voltage. 1.2 i believe. 3750 orso needed more but there are so many steps in my bios that i just put it to 1.3. however 4 g didnt run and just set it to 1.4 so i believe with some more testing i can get it somewhere between 1.3 and 1.4. with some more reading to do about gtl tweaking maybe i can get it at 1.3 or lower. we'll see :) Link to comment Share on other sites More sharing options...
DerekT Posted February 25, 2008 Share Posted February 25, 2008 Thanks for the information. I'll be moving to the E9450 once they are released and some testing occurs. I want the cooler and quieter and of course, 4GHz is the number :D: Is the 1.4 Vcore BIOS? I agree with you on the GTL research. GTL tweaks have a profound effect on overclocking at the more extreme ends. Link to comment Share on other sites More sharing options...
Kingpinda Posted February 25, 2008 Author Share Posted February 25, 2008 Yes vcore in bios set to around 1.4v I just saw a few chaps who listed their overclock with the e8400 at 4g's and they had both had their vcore set at 1.375 so you might try that first. tonight i'm gonna put it there also before i go sleep and prime untill i wake up Link to comment Share on other sites More sharing options...
