sounds like you need to clear CMOS. Very common after an unstable overclock.

On VTT it's more if you are running a DRAM Voltage of 1.65v you don't want your VTT below 1.15v. With a VTT of 1.31 there isn't much need to worry about it unless you are trying to fry your RAM at over 1.81v.

thanks. removing battery did not help. again, set vcore to 1.15 - ant booted successfully.
I will give another attempt to go for 3.8 today.

not good... I do not like this. What have I done wrong? I can boot to Windows, but at prime or intelburn test starts I instantly get error and program shuts down

p.s. to boot windows i set Vcore to 1.35 now. All C states, EIST and turbo disabled.

Worried for you... There shouldn't be any problem after loading optimized defaults. Before doing any overclocking I'd find the problem here first. First thing I would do is Pull the CMOS baterry and leave it out for a good 20 minutes or so just to be sure then try optimized defaults again. Next I'd update to the latest BIOS. Also double check that the stock RAM settings are within spec for your RAM. Then run memtest86+ to check for errors.

I have clearly problems with mobo. I think... That thing, when optimizing defaults would not boot into Windows, worries me too.



So, I did some tweaking. Why cpuid show different vcore than bios? Which one is true? I think enabling LLC helped me. At least now I can run Prime tests. Highest temps are 64C on full load. Should I be running it like that? I think in BIOS my vcore is 1.32 now with LLC enabled.

Well, for starters, I'd be jumping CMOS, not just removing the battery. Do it w/ the power on, do it w/ the power off. Then pull the battery OVERNIGHT. (This saved a P5B Deluxe for me) When you wake up, go through all the BIOS options and setup everything for STOCK. Stock CPU, Stock RAM, Stock GPU, etc. Make sure it's completely stable before even beginning to mess w/ clocking. If it is, then SLOWLY start to bring things back up again, 100 Mhz @ a time w/ LinX runs, followed by gaming sessions. It's A LOT less frustrating than going for the high number after instability.

As for the differing Vcore, I've always thought CPU-Z to be more accurate than the BIOS. Don't really know though, lol!

Good luck!

You did hit F7 right ?...
Did you try loading the Fail-Safe defaults (F6) ?
F10 to save...... Hey I might have known somebody that forgot to do that one time.




Vdrop and Vdroop as well as LLC (Load Line Calibration) and it's effects on Vdrop/Vdroop. The Voltage setting in BIOS is nearly always off from the actual voltage.

CPU-Z is accurate enough unless you feal like using a voltage meter. Which isn't such a bad idea if you are going to push it to the stops.

Battlefield absolutely destroyed my overclock wow, then I restored everything to default, still crashes , means I got faulty hardware or drivers

@EKKO! DO NOT USE TURBO! If I hadn't gone into that i5 4ghz link, no one would have known, what are the rest your bios settings?

@asnedaigas, no use turning of c-states or putting your voltage that high. Try test cpu with occt, tell me what happens, intel burn test could be bullshizing you, but I doubt that prime is.

@sizzle, nice clocks and volts.

Oh and C6 state causes shut down when my pc is on idle, all windows power management things have been switched off, so no effect doing that. Anyone else have problems like this?

Seems like people with gigabyte p55 ud3 boards aren't having a good time.

i have the UD3R, i got my cpu up quite high http://valid.canardpc.com/show_oc.php?id=1517348

Well sure you're lucky that you can clock on that board with practically the same cpu. But your results sicken me, sorry to say and I mean no offense, it's just my opinion. I bet you could get practically the same with a lot less volts, would make the cpu last a few months longer too.
