Nice one C-N, looks like a keeper.
are you FN kidding me man, nice 2500K now :rolleyes::mad::D:rofl::up:
Awesome chip perfect for 5g 24/7, its got to break in voltage wise but atm she runs linx 5g at 1.32 bios! Low 60's
Nice to meet you all. Hot stuff going on here!
Just want to share the pain with some of you, I have that cold boot problem as well(some times it goes three times straight one after another). First I thought it was my HX650, after roaming in forums searching for answers (and unplugged my HDDs, HDD fans, USB port PCI) I almost bought a new AX650, but fortunately I found TurboDiv's posts LoL.
I have another PCI device left, a wi-fi antenna thing, so I might take that thing off and put back my HDD & co.
As Ram, I have RipjawsX set @1600CL8-8-8-24 1,56V.
I'll let you know how it goes..

Nice chip, C-N. What batch #?
Thank you :)Quote:

I think its just random luck with these chips from what I see voltage & speed vary wildly irrespective of batch.
Just added a small bit of info to the top of post 2.... http://www.xtremesystems.org/forums/...30&postcount=2
I have one of these PCI Diagnostic cards cost me £1.50 from Hong Kong & it works a treat.
TurboDiv's assumption was right I guess. I emptied all my PCI slot, stock clock, RAM tweak from the readable 1333 CL9 to its native 1600 CL8, everything else are stock settings. I run stressing and testing, no errors, only the normal-sometimes-twice reboot when I turn it on or on restarting. But as soon as I put the PCI card back and turn it on, I get error message saying there is system instability due to overclocking voltages and stuff.. and BIOS get revert to factory settings, except the RAM voltages(my setting is 1.56V and stock is 1.5V, and after error message is 1.526V or something).Quote:

Very interesting.... something for the GB boys to look into I think, Although I have used both a PCI video card & my PCI diagnostic card without fault.Quote:

what PCI devices are being used and in what configuration
specific models please and how it affects the board so it can be easily replicated?
Dinos: Soundblaster X-fi Fatal1ty.
@Dinos
Netgear RangeMax WPN311 Wireless PCI Adapter
Belkin USB 2.0 Hi-Speed 5-Port PCI Card
Stable system, turned system off to put PCI devices on, turned system on, wham! BIOS setting reverted due to unstable voltage/overclock message came out ( happened more than once)
Beside of that, can anyone tell me why CPU-Z shows x 37 multiplier while I set it up to x 40?
Yes, I disabled C3/C6, Thermal Monitor, C1E, EIST. Yes, I ran Prime95 and IntelBurner, but it still showing x 37. (core temp shows x 33 lol)
What did I missed?
Try clearing the CMOS. Also make sure the turbo options are disabled (so all cpu's use the same multiplier, and the independent multiplier settings should all be greened out).
Thanks. I did, but it was the same. So I tried to change all the cores' multiplier one by one before blued(or greened) them out by disabling the Turbo, and it was the same.
So I tried the same thing, plus enabling Real Time Ratio in OS.. And it worked! :D Sorry, first time build and first time overclocking :shakes:

Usually a cmos clear with the power plug disabled fixes weird stuff like that.
Though I flashed f6d in MS DOS with spiflash.
I disabled real time ratio in OS, always kept it disabled, and I always had everything else disabled (except bi directional prochot), and I never had a problem with the multiplier lowering.
I also have all power saving stuff (besides screensavers) disabled in windows.
Oh, I didn't reset the cmos. I'm using F6. Actually I too disabled everything else, but somehow it didn't worked with real time ratio disabled. Couldn't be bother to reset cmos at that time.Quote:

Hey guy, sorry to hear you got that nasty bug like me. For the record, I also have a Creative X-Fi Xtrememusic on one of the PCI slots. I was extremely annoyed with all of this cold boot issue and (knock on wood) i think i might have cracked it for the last 2 days. I don't want to bring anyone's hopes up but it appears to be extremely related to the CPU clock + PCI card + the power line of the house going to your system + the quality of the Active PFC on your power supply unit. ( Did i just mention like 90% of the components, lol)
So what i did first was bought a voltage regulator that connects my rig + monitor only and as soon i fired it up it registered that my line was overvolting and the unit was correcting it. Next i lowered my CPU down to 4.6 ghz and left the voltage a little bit higher - same as for my 4.9 ghz stable clocks. Ram was set to 2133mhz Cl7 as with its specs. At these settings my machine was having problems cold booting before w/o the voltage regulator but now it seems to be running fine for the last 2 days w/o any cold booting issues. At the same time i noticed a bit higher values for the 3,3v line from ET6 with the voltage regulator which suggests that the Active PFC of my power supply was not coping properly regulating the voltage from the house line. Also i noticed that BCLK exactly at 100mhz was making things more stable than to let the mobo default it at 99.8mhz.
First i would suggest to try and lower your CPU speed down to like 4.4 ghz with memories at the right specs and slowly build it up multi by multi until it starts cold booting or if it is cold booting w/o any CPU overclocks try and get a voltage regulator - it is always better to have one anyways (~30$). Right now if i increase the CPU multiplier to 47 it has issues cold booting from the first time but it is stable once it boots to windows, up to 49 multi with 2133mhz ram. This is all still testing things but so far i had like 5 successful cold boots w/o any problems with 2133mhz ram (XMP - profile1).
DEFINITELY reset the cmos. I found that the board was giving me 8x PCIE at 100 mhz (auto) and 99.8 and below, but was giving me 16x at 100.1 or 100.2. When I reset the cmos, auto gave me 16x PCIE again.Quote:

I'm still here, trying to figure out these Gskill's and working on picking up a 3rd 2600k ..............................
Not that I've seen, perhaps PM Dinos & ask as he got one for the UD4 & 7.Quote:

Goes without saying dont poke about if you not happy doing it!!!!
I find all but the VCore to be believable but as Sin said the choke voltage hasnt gone through any caps at this read point so :shrug:
If anyone has measured the VCore on the back of the board like we did with X58 & finds it more believable please let me know.
Any reason the UD5 is lacking a bios update when UD3P,UD4 and UD7 has new improved bioses ?
