What model is your ram? what are you running it at?
Thanks for your reply mate.
Ram is Corsair XMS3 1333C9DHX. Everything is on AUTO. I have set command rate to 2T before, as it supposedly helps stability with this board. Running it at 1333mhz as its suposed to be.
As for repairing my Vista install, it is not needed. I just load up defaults in BIOS, and set Boot device priority to CD rom ONLY. Then let it search for a cd, and when it doesnt find anything, I reset, change boot device priority to Hard drive, and it'll boot up from the hard drive just fine, as if nothing had ever happened to it.
Its worth trying dont you think? While its doing the problem I mean. I suggest changing PnP OS to enabled, boot priority to Hard Drive.
x64 or x86? It might be boot the boot loader. Don't use Level Ups, go manual. Keep FSB linked and synced with ram at 1333 with enough vcore (I would say 1.34~1.36) and stock voltage and timings on ram (check on manufacturers homepage), PLL at 1.52, VTT at 1.34, NB 1.44, SB 1.5, CPU GTL refs +42 +39 +39 +42, NB and DDR3 REFS on auto.
When you say Auto, do you mean voltages, timings? Do you overclock with auto?
x64 vista. I did have x86, and the same problem happened with that as well. As for this error it doesnt happen anymore. I've deliberately bluescreened it by not giving it enough voltages. It has booted up just fine 3 times in a row now. As for PnP OS, I thought you said to disable it 2 posts back? If this problem happens again, I will be sure to try repairing vista with the boot cd.
When I say AUTO I mean everything that I didn't otherwise specify. I have got it running 1500 fsb now, but for some reason my Q6600 needs a LOT of vcore. 1.536v after vdrop just to stay stable at 3.375 ghz.
PNP OS should be disabled when using Raid or having boot issues IMO. Way too much, if your VID is 1.26 you would need 1.34 to 1.36 max with Loadline Calibration. With LLC I need 1.42 for 3.6 GHz and 1.54 for 3.8GHz and 1.6 for 4.05GHz. Oh yeah, forgot to mention my cpu is q6600. Are you running 1500 MHz ram too?
PnP OS is disabled now, no issues at the moment. No, running RAM at stock 1333 mhz at stock timings with 1T command rate. Should I set it to 2T?
VID of my cpu is 1.3v. I've set vcore to 1.475 with loadline calibration off. I cannot run 3.6ghz with 1.5vcore and loadline calibration enabled. Always a blue screen or a restart. Sometimes a quick blue screen saying "Parity check/ memory error" then a restart.

EDIT - It Froze on a BSOD stop 1

I tried 2T, and it froze up and bluscreend, and then restarted. I've given it more vcore (1.425 with loadline cal enabled, and 2T now).

OK, set everything like you said there. Boots up fine. My RAM has a sticker that says 9-9-9-24 1.5v on their sides. Dont know if that helps? Actual reported voltages by EVEREST are now:
Vcore: 1.46
VTT: 1.36/38
PLL: 1.55
VDIMM: 1.66/68
NB : 1.47
SB: 1.49/50
Cpu-Z reports: 1.456 IDLE, and 1.408 LOAD.
What next?
Jesus! :shocked: There's a great chance you damaged your ram, I thought it was the model that runs on 1.6v :shrug: Mate, check the stickers on all of your ram, if all say 1.5v then set 1.5 on Memory Votlage ASAP.Quote:

Set RAM to 1.5v. I didnt think too much of it at first, They've been getting 1.66 v from the board since September last year. When I first built the pc, I did not have a clue about voltages etc. So on stock its been getting .16v over what its rated for. My RAM reports no errors in Memtest anyway, did 2 full passes. Surely they'd be getting problems by now? Maybe i am just REALLY REALLY lucky that they arent produced errors yet?
As for vcore, I just checked in BIOS voltage monitor, Vcore reports as : 1.44. Cpu-z (v1.50) in windows idle reports 1.456v. Load is 1.392v. These voltages seem all over the place dont they? LLC is disabled.
Luck is not enough, DDR3 is sensitive to votlages, 2 memtest86+ passes is not enough, leave it overnight or at least 6-12 loopss to check for any errors. To be honest I think you should try booting with 1.36v actual in bios (on load 1.30 -1.31) and run small FFT's in prime95. If it's unstable it should BSOD you immediately.
well the most stable setting I have found so far ir running the cpu on auto and setting that ram profile as suggested by the mfr:Quote:

As for my VDIMM now, I set 1.5v in BIOS. Everest reports 1.58/59v.
What should I do now? vcore seems a lot higher than what it should be yes?
That's because your cpu needs more voltage. You could try running ram at stock timings, that is most on Auto (including DDR3 REFs) except tCL, tRCD, tRP, tRAS, tRC and tRFC and stock voltage (not the actual, if it says 1.9 then set 1.9 in bios for now).
I don't think cpu-z or everest should be trusted with this board. From my experience, your ram is probably running at 1.52 - 1.54v. On vCore I meant the actual voltage (in bios or pc probe II) should be at 1.36v.Quote:

EDIT - Ill install PC Probe II, see what it says..
These board utilities piss me off when I have to install them too :yepp: But since I need them... :shrug:
PC Probe II reports Vcore as 1.42, Load it goes down to 1.38v. Is this OK?
EDIT - So long as I know what they are set at, there should be no problems right?
Yeah. Set vCore at 1.3 in bios and check PC probe for the actual. You goal is 1.36 actual. What does pc probe say about ram voltage?
I set vcore to 1.3v, and as it booted it restarted. BIOS reported 1.36v, but couldnt get it into windows with those volts. I've set it at 1.325v now. ASUS PC probe reports 1.38 vcore, and 1.58 VDIMM.
EDIT - 1.35vcore seems stable so far.. done 15 minutes,
Hm, VID does make a bigger difference than I thought. Same scenario though find where you are stable with small fft's at least an hour and once you think you found the appropriate run prime95 again for at least 4 hours. Hm, vdimm is still quite high, but from what I understand you report the highest value you detect rather the dominant/average. Perhaps you can average it at 1.52 actual thus 1.48 in bios. But to find the appropriate ram voltage (though on stock timings and frequencies) there's technique I found that works great. Run IntelBurnTest latest version, maximum stress and monitor cpu and ram usage (task manager is fine, performance tab). This only takes a minute, once you run IBT it consumes all of your memory then it starts stressing CPU, once it starts on CPU exit, do this twice. You see if ram voltage is low, this technique will freeze your pc. Once you find the voltage that is stable test it with prime95 blend for at least 4 hours.Quote:

Lowest I can set RAM voltage is 1.5v. I did try the technique you suggested just now. I did it 4 times, just to be safe, didn't freeze at all. Running Stock frequencies and timings but with 2T command rate. maybe try 1T?
EDIT - Dont know if my RAM is totally OK though. i was just watching a video, and was surfing the web, and it sort of "froze" for 1 second with the sound looping in the vid, like a short stutter. But its ok after that.
I'm not the one to make that decision for you. But I can tell you my opinion, it would probably create instabilities and the performance you get out of it is little. It will not harm your ram but there's a slim chance it might corrupt your OS. You are better of enabling P1 and P2 since it takes it out on vNB (1.44 is fine for your system IMO), which enhances some mch internal timings which gives you some memory read/write improvements.
EDIT: AnandTech suggests that 1T would be good up to DDR3-1860 with 2GB ram. You fit the speed, but not the size. I am not saying there's no chance but I can say that it will be hard.
Alright, i'll leave it at 2T for now. Ill forget P1 and P2 for now as well. Ill run memtest all day tomorrow then, see what it'll show.
That would be a good idea, especially before these 2 changes.
