psycho13 Posted January 26, 2011 Share Posted January 26, 2011 Could you please tell me if you tested this pair of memory/mainboard and if there are no known issues, what are the best settings for these? I'm not interested in overclocking, but I would do some if it ran with the stock coolers and if it would get me rid of the BSODs. When i start up the comp after being allowed to cool off, it enters Windows, does a BSOD with MEMORY MANAGEMENT and restarts. After it warms up, starts up no problem. Please advise to BIOS recommended settings for MOBO, CPU and memory. Thank you in advance. Below is my CPU-Z report.

psycho13 Posted January 27, 2011 Author Share Posted January 27, 2011 Thank you for removing the useless stuff in my post.

psycho13 Posted January 27, 2011 Author Share Posted January 27, 2011 Thanks a million. I'm going to shut the rig down.....hope it works in the morning. Edit: Well, I started her up this morning, two restarts then working fine. So i'm not quite in the clear, but improving. Maybe I need to fiddle around with the settings some more. It says that XMP profile 2 should be 8.0-8-8-24-41-2T @ 800 MHz (1.650 Volts). WHat exactly is the 41? Because my Row Refresh Cycle Time (tRFC) is 88. I hope that's not it. And if it is, should i manually input 41? Sorry about all the bother. Link to comment Share on other sites More sharing options...
psycho13 Posted January 30, 2011 Author Share Posted January 30, 2011 Anyway, i seem to have what is called a Cold Boot issue. The first time i started my rig it worked fine. I left on for about a week and had no issues. The next boot up, it BSOD-ed and restarted two times, went into windows repair and then worked. Kept it on for about two weeks. Next boot-up, same thing. This week, it would not start at all. A lot of restarts, even went through "no boot disk" error. The BSODs are about memory management. Memtest when it doesn't start showed about a trillion errors, after it starts no errors. any advice about that? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 2, 2011 Corsair Employee Share Posted February 2, 2011 I would test the modules one at a time with http://www.memtest.org, if one of the modules is causing that the problem will show up when you test them one at a time and the other will run with out problems, in which case I would suggest getting an RMA and get them replaced but if they all display the same symptoms then check with the MB maker for the latest BIOS and see what they say.

psycho13 Posted August 4, 2011 Author Share Posted August 4, 2011 Okay, so i tested the modules and they're fine. Flashed the BIOS to the latest stable version(FF), still having issues. What are the recommended timmings and voltage settings for this to run at normal spec? Do i have to overclock the processor? Link to comment Share on other sites More sharing options...
peanutz94 Posted August 4, 2011 Share Posted August 4, 2011 What are the recommended timmings and voltage settings for this to run at normal spec? 8.0-8-8-24-41-2T @ 800 MHz (1.650 Volts) Instead of enabling XMP try entering them in manually. For some reason XMP does not work for some users. Timings and voltages are always printed on the labels of each stick. I would also make sure your memory controller voltage is set to 1.35v as well. (QPI voltage) Do i have to overclock the processor? You already are ! Since the memory controller is now on the CPU , when you overclock the memory as you are, it is in fact overclocking the CPU. There is always the possiblity that you CPU wont allow you to run the RAM anything higher than stock 1333mhz. The 950's are probably the worst chips for overclocking. They seem to have the weakest memory controllers out of all the 1-7 series CPU's Link to comment Share on other sites More sharing options...
psycho13 Posted August 4, 2011 Author Share Posted August 4, 2011 Are these settings OK? I don't really understand what the 41 is !

Corsair Employee RAM GUY Posted August 5, 2011 Corsair Employee Share Posted August 5, 2011 This should be fine but I would try and set the memory Voltage to 1.64 to 1.65 and see if its still stable. Link to comment Share on other sites More sharing options...

Corsair Employee RAM GUY Posted August 5, 2011 Corsair Employee Share Posted August 5, 2011 Try it at 1.64 Volts and TRFC would be 41 but test with http://www.memtest.org And I would try and increase the QPI Voltage from 1.35 to 1.375 or 1.40 Volts Link to comment Share on other sites More sharing options...
psycho13 Posted August 9, 2011 Author Share Posted August 9, 2011 it won't boot at all with these settings(overclocking failed) ram 1.66v ram multi 12 qpi/vtt 1.355v uncore multi 24 cpu multi 23 QPI 36 ram timings are 8-8-8-24 with 2T One more question: if the command rate is 2T does that double the effective frequency(if the multi is set for 800 MHz, with 2T is it 1600?) With the QPI/VTT i'm already in the red on the mobo(1.355), should I up it one more time? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted August 9, 2011 Corsair Employee Share Posted August 9, 2011 Yes I would try 1.375 or 1.40 for the QPI Voltage. Command Rate is not really a memory setting and would be dependent on the make and model of MB and PSU and the specific CPU you have installed. You might look this/those setting /'s up on the BIOS Optimization Guide at Techarp and get a better explanation. Link to comment Share on other sites More sharing options...
psycho13 Posted August 10, 2011 Author Share Posted August 10, 2011 okay, i upped the qpi/vtt voltage to 1.375 and it booted up fine. The temps are fine, last night it worked ok, but this morning BSOD with the same settings: ram 1.66v ram multi 12 qpi/vtt 1.375v uncore multi 24 cpu multi 23 QPI 36 ram timings are 8-8-8-24 with 2T Should I increase the DRAM termination voltage also?

Corsair Employee RAM GUY Posted August 11, 2011 Corsair Employee Share Posted August 11, 2011 NO absolutely not, the only voltage I would adjust and only if needed would be the CPU/QPI Voltage no more than about 1.45 Volts if you have a (D0) Stepping CPU.

dhstsw Posted May 31, 2018 Share Posted May 31, 2018 Hi, i have the "dishappearing" ram problem with this kit (actually, 2 of them - for a total of 12Gb) and a GA-X58A-UD7-V2, bios FD and a x5670 xeon processor. I had it last year, then it went away by itself. Two weeks ago, it started happening again. The problem is the same as in this video: [ame] [/ame] Usually, from a cold start, the pc boots up in windows: after a few seconds (or minutes) i get a BSOD and after a reset, at startup, the computer detects only 8Gb of ram. After minutes of fiddling and many resets, the PC reports 12Gb again and works flawlessy... The morning after (cold start) the same happens. By now i tried tRFC of 128 (wich is what i get from "auto"), 80 and, now i tried 100 (i know if there will be any difference tomorrow i guess). I see in the thread you advice to put "41" for tRFC. If 100 fails i'll try that. Any other advice? I'm going crazy. Link to comment Share on other sites More sharing options...
dhstsw Posted June 2, 2018 Share Posted June 2, 2018 So, i found out that my board, as "safe" or "optimized" settings sets 108 for tRFC on channel A and 74 on channel B and C. That leads to crashes and one channel to dishappear on cold boots. It may be very well the bios or the board itself, even if i don't think so (as i see it was a very common problem on X58 boards from various manifactures and various ram models/makers). Imposing a fixed parameter for all three channels fixes the issue (100 or 74 in my case). So, even if it's old tech and stuff, if that happens to anybody else they know how to fix the problem. BTW: XMS reports only 1 profile and it *never* worked correctly (at least, on my board). Cheers. Link to comment Share on other sites More sharing options...

From the limited experience I have on X58 and what you have seen, I do believe the bios to be the culprit. -Art Link to comment Share on other sites More sharing options...
