DrMunkey Posted January 17, 2008 Share Posted January 17, 2008 Problem is I'm using Vista Ultimate 64-bit, and with all 4 memory modules installed, Windows gives me a BSOD during OS load screen that says "IRQL_NOT_EQUAL_OR_LESS" or something like that and then proceeds to do a memory dump. It doesn't matter which memory set is in the 0 & 2 memory slots (they're paired), the system works fine. As soon as I put 2 sticks in 1 & 3 in addition for a total of 4, the system gives me that problem. I have yet been able to get all 4 sticks to work properly and I don't know if this is a known issue with my setup or what the problem may be. Any help would be greatly appreciated. As I write this, I was wondering about sticking memory into the 1 & 3 slots only to see if it might be an issue with those slots. Will post an update in a few minutes.

DrMunkey Posted January 17, 2008 Author Share Posted January 17, 2008 So, after toying around with everything, my system apparently doesn't mind 3 of the sticks, it just minds when all 4 slots are full. Doesn't matter which 3 of the 4 sticks I have in, or in which slots they exist in, the system performs great like that. Any ideas why my setup won't take a full 4GB?

Yoxxy Posted January 17, 2008 Share Posted January 17, 2008 EVGA Board and 680i in general has problems with 4x 1GB. You need to raise FSB Termination to 1.40, NB voltage to 1.40v. This should get you stable. Also try changing MCH-SPP reference to 3x from 5x. -OXXY Link to comment Share on other sites More sharing options...

This should get you stable. Also try changing MCH-SPP reference to 3x from 5x. -********Y OK, so I'm not totally sure what you meant by some of that. What I ended up doing was changing the "CPU FSB" to 1.40v, as I figured that's what you meant by "FSB Termination to 1.40." I changed the "HT nForce SPP <-> MCP" to 1.40v" as well figuring that might be what you meant by "NB voltage to 1.40v." Then I changed the HT Multiplier only uni-directionally. It showed the option to change "nForce SPP <- nForce MCP" and the option to change "nForce SPP -> nForce MCP." I only changed the SPP <- MCP to 3x and left the SPP -> MCP at 5x, should I have changed this in both directions? Sorry for my ignorance when it comes to some of these terms. I figured MCP = MCH since that was the only thing close to what you had typed I could find. What kind of performance is that affecting bumping the multiplier down to 3x? Thanks, your help is much appreciated, I sure would like to be able to utilize all 4GB that I had bought for this machine. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 17, 2008 Corsair Employees Share Posted January 17, 2008 Try setting the nForce SPP to 1.3 to 1.4 Volts. Link to comment Share on other sites More sharing options...
DrMunkey Posted January 17, 2008 Author Share Posted January 17, 2008 It's working flawlessly now with the HT multiplier bidirectionally at 5x. I have the HT SPP <-> MCP at 1.40v and the CPU FSB at 1.4V, the SPP at 1.4V and the MCP at 1.5V (the auto default) and the CPU is running at 1.31V (the auto default as well). Thanks to both of you guys, it's nice to finally be able to use all my hardware. It makes a huge freakin' difference in Windows Vista! Link to comment Share on other sites More sharing options...
DrMunkey Posted January 18, 2008 Author Share Posted January 18, 2008 Last post retracted, the first time I went to reboot, the system hung at shutdown and then shutting off and attempting to load back into windows put me back at square one with BSODs at every windows load screen. I just don't get it... I can't find a stable setting to keep all 4GB in my machine. Any help is appreciated. I am almost tempted to just buy a 2x2GB set now...

Corsair Employees RAM GUY Posted January 18, 2008 Corsair Employees Share Posted January 18, 2008 Are you running the memory frequency at DDR667? If not I would suggest that and for sure 2 modules would be better than 4 any day. Link to comment Share on other sites More sharing options...
DrMunkey Posted January 19, 2008 Author Share Posted January 19, 2008 Are you running the memory frequency at DDR667? If not I would suggest that and for sure 2 modules would be better than 4 any day. No, I was running the modules at DDR800 since that was what they were rated. Now, apparently I can't even use 3 of the sticks of memory. The system is still unstable with only3 sticks in very strange ways. USB devices don't function correctly (i.e. my palm won't sync). It is very strange how everything reacts. I'm almost tempted to get a different motherboard... Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 22, 2008 Corsair Employees Share Posted January 22, 2008 Please try setting the memory frequency at DDR667 and if you still have problems I would set the tested settings and test them one at a time to make sure one is not failing.

DrMunkey Posted January 22, 2008 Author Share Posted January 22, 2008 but then I lose the benefits of running DDR-800 which is why I bought that particular RAM instead of DDR-667. At any rate, I have ordered a 2x2GB set and am hoping that that will solve my problems and just E-bay off the 2 sets of this stuff for $50 a set. We will see in a few days when I get the new RAM.

Corsair Employees RAM GUY Posted January 22, 2008 Corsair Employees Share Posted January 22, 2008 Two 2.0 Gig modules will run at DDR800 so that should resolve the issue. But this is a limitation of the chipset/Memory controller not the memory. Link to comment Share on other sites More sharing options...
DrMunkey Posted January 22, 2008 Author Share Posted January 22, 2008 What are ideal voltages I should have everything set at to start off with? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 22, 2008 Corsair Employees Share Posted January 22, 2008 What is the part number of the modules you want to know about and how many modules and please tell me the make and model of the MB in question and the CPU speed and its FSB. If its in your list then please state that or list the MB and configuration in question. Link to comment Share on other sites More sharing options...
fremel Posted February 4, 2008 Share Posted February 4, 2008 Dont know if u applied this patch but its needed to run with 4gb of ram (not just install as the article says) http://support.microsoft.com/kb/929777 /Fremel Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 5, 2008 Corsair Employees Share Posted February 5, 2008 And if its XM2S-6400C4DHX like whats in your list 2.1 Volts and set the memory frequency at DDR667 with 4 modules installed. Link to comment Share on other sites More sharing options...
lwilliams Posted February 6, 2008 Share Posted February 6, 2008 I am having the same problem. MB is EVGA 122-CK-NF68 2 of TWIN2X2048-6400C5DHX G 2 of XMS6405v5.1 All 4 sticks are DDR2 800mHz. With all 4 in the board, all I get is a long, steady beep tone at startup and no POST. With ANY 3 sticks, it works perfectly. Win Vista Ultimate, all updates. Anything to do? Bios update maybe?

Corsair Employees RAM GUY Posted February 6, 2008 Corsair Employees Share Posted February 6, 2008 with a working module set the memory Voltage to 2.0 Volts and set the NB/MCH Voltage to +.05 Volts and set the memory frequency at DDR667 then exit the bios saving changes and let it try to boot from a floppy or CD and then turn it off and install all of the modules and see if it will post.

lwilliams Posted February 6, 2008 Share Posted February 6, 2008 Well, I am posting this right now with Windows reporting 4mg of Ram. Won't I have a severe performance hit by moving the Mem bus speed down to 667mHz?? Also, I could not find anything that said NB/MCH in the BIOS anywhere.

Corsair Employees RAM GUY Posted February 6, 2008 Corsair Employees Share Posted February 6, 2008 If the system is not stable then no you will not and in fact it will probably solve any stability issues. Also the NB/MCH Voltage might be called NB SPP Voltage, you want to increase the Memory Controller Voltage is what you are looking for. Link to comment Share on other sites More sharing options...
lwilliams Posted February 6, 2008 Share Posted February 6, 2008 Do you mean if the system IS stable??? or NOT stabel?? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 6, 2008 Corsair Employees Share Posted February 6, 2008 LOL is your system stable at DDR800 with 4 modules? If Yes then why are you posting? If not then please try what I suggested. Link to comment Share on other sites More sharing options...
lwilliams Posted February 6, 2008 Share Posted February 6, 2008 Yes, I am having no issues. The only thing that is a little strange, is my HP printer software wants to reinstall and is asking for the disc. Any reason you can think of for that?
