Problems with GA-EX58-UD5 Overclocked bundle

Just had a quick play with overclock settings.

New profile from OC has definently solved the warm boot / restarts.

However the cold boots still have problems (first boot of the day is always fine though)

I tired downing the multiplier so the chip was only overclocked to 3ghz, but this still caused an issue (left the rest of the settings as they were in OC profile)

I then loaded the standard settings and did a basic overclock to 3.5ghz (no voltage / ram changes). This loaded fine everytime, and the system seemed stable. Also on a normal bootup, i only got 1 test cycle.

By test cycles i mean this:

When the computer starts the Graphics card will fire up to full speed, then slow down (This is 1 cycle, the diag display will show C1, then blank, then come back)

Generally with the overclockers profile i get 3 test cycles, then the system will start.

On cold boot after the system being on, the computer will come on, then go off very quickly.

I then get it back and get 3-4 test cycles, then the power goes off again.

Then power back, 1 test cycle, and systems starts with O.C error.

Any ideas? Maybe the voltages need playing with. I tried setting some of the voltages from AUTO, to their actual running settings, but couldn't actually get it to boot with that profile.
 
My opinion is you should RMA it.

You bought an overclocked bundle.

You should not have to change settings to get it to boot - thats the whole idea of getting Overclockers to do it for you - it should work 100% out of the box.

I know you didn't want to RMA it because of the turnaround time, but I think you have been more than patient with the system, more patient than I would have been anyway!;)
 
Any chance you could post up some of the BIOS settings of the overclock that result in multiple restarts?

Thanks to everyone for their help and suggestions so far :D
 
Personally I would be concerned by QPI/VTT being set to AUTO. Try setting it to 1.3 and see if it boots. If it doesn't, bump it up a bit more - Don't go over 1.35 though as this is what Intel recommend as the maximum. My guess is that the mobo is setting this far to high whilst on AUTO.

Also What speed is your RAM running at? And what speed can you RAM run at?

Where are you getting the actuals from, not the bios values? You'll need to load easytune to get the values to replace the AUTO field. The uncore is running on x19 3800MHz, seems a little high for starters. Try x16 to begin with.
 
I used some of the running values from easytune yes. But everytime i booted these would change. i will run easytune now and post the current values (with board set to auto)

The uncore x19 setting is what overclockers provided so i assumed it would be fine. I tried x15-x20 but they all gave the same booting problem.
 
Also, what sort of temps should i be expecting to get at idle and load? I have noticed an increase since the F10 update, although i must admit i only really did a proper temp check when i first installed the system.

The Uncore multiplier value should be derived from the Memory Multiplier. It should be x2, or x2 +1 the value of the Memory multiplier e.g. If Memory Multiplier is 8, Uncore should be x16 or x17, if Memory Multiplier is 10, Uncore should be x20 or x21

Memory, to start with you set it as near to the rams stock speed as possible. You can of course overclock the ram, but the jump to the next multi can be quite large. Set everything you can manually. AUTO settings can be a pain, especially ones tied to Turbo modes or vcore. You never know what they're going to do, I've seen countless potentially damaging overvolts from AUTO settings.

I assume from the profile its PC3-12800 (DDR3-1600), so the x8 is correct at 200 BCLK. PC3-16000 (DDR3-2000) would be stock at x10 @ 200 BCLK.

Have now managed to get rid of the restart / cold start issue by setting the QPI/VTT to 1.340v (couldn't boot into windows with anything lower than this)

However when i run a stress test i get a lovely BSOD.

The next setting up is 1.360v which is above recommended levels.

I'm going to try adjusting some Ram / multiplier settings and see if i can get it to be more stable
 
Bit stuck at the moment. Can't get it to run at 100% cpu with QPI set to 1.340v, can't get it to boot with any less than that. Apparently the max recommended setting is 1.350v. Can anyone suggest any other settings i can change to get the system to behave?

Also i found out that ejr22 was probably right and that having QPI voltage set to auto was causing the booting problems. So just need to find a happy medium where i can boot and use my computer!

Thanks again for everyone's help and suggestions so far :D
 
1.35 is only an Intel recommend maximum - I doubt whether Intel recommend overclocking either so I wouldn't worry about trying something slightly more, 1.4 etc.

Obviously with increased voltages the thing to keep an eye on are your temperatures. Obviously the more you raise the voltages the more heat it will create.

If you don't want to go over 1.35v on the QPI (or you find that it is to hot over this) the only thing I can think of suggesting is to try setting your RAM multiplier to x6 (remember to change your uncore frequency to x12 or x13 at the same time) - it will mean your RAM will run a 1200MHz but you won't notice a difference between that and 1600MHz. Alternatively if you aren't happy with that you could always try loosening your RAM timings, something like 10-10-10-30.

Also, make sure you DRAM Voltage is set to 1.66.

Well some damn good news!

I seem (fingers crossed) to have it stable and got rid of the cold boot issues!

Here is what i changes from O.C profile:

As eir22 suggested, the QPI being set to auto was wrong. have now set this to 1.340v.

Then as fornowagain and eir22 both suggested, the Uncore multiplier was wrong. Have set this to 16x (giving an uncore freq. of 3200MHz). Also changed SPD to manual @ 8.0.

QPI link speed is set to auto and is running @ 7.2ghz according to bios

CPU clock ratio is 20 and BCLK is 200 giving me 4GHz

CPU Vcore is currently 1.33750V.

Other settings are:
CPU Clock Drive @ 900mV (Set by overclockers i think)

Together the system seems stable, and currently has no cold or warm boot issues (although i will be testing over the next few weeks to make sure)

What sort of temps do people get with a 4GHz overclock @ stress and idle? My temps seem to have gone up since new BIOS and am wondering if it is worth reseating heatsink since i have been poking about in there.

Thanks again to everyone for their input, hopefully this has bought my overclocking nightmare to an end! I have learnt quite a bit about overclocking and shouldn't have been so lazy to let a company do it for me! It was much easier with my socket A athlon :P

Will keep you all advised on stability of the system.

Special thanks to mirx, eij22 and fornowagain

I hope i'm not jinxing it by posting my findings! :D :D
 
Oh an as for my keyboard, i have a spare PCI USB card which i will try. Currently I have the keyboard plugged into the screen and i don't turn the screen on until the computer is past POST (the USB ports don't work on the screen unless it is on) A bit of a dodgy way round but it works for now!

Just regarding the keyboard - is it a USB 2.0 connection? Although it should still work and not cause booting issues if it is not plugged into a USB 2.0 port, it might be worth checking that it is plugged into one of these ports just to eliminate a possible cause. You might also want to check out the Logitech support forums, it seems like you are not the only one with this problem.

Temps-wise. Idle temps are obviously largely affected by the ambient room temperature and as long as it isn't running massively over this it'll be fine. Load temps for 4GHz on air??? There will be quite varied opinion as to what is considered normal or safe but personally I think that you should try to stay below 80c. I think the i7 can go all the way up to 100c before throttling itself but you don't want to go anywhere near that, clearly.

I wouldn't be too concerned with the 1.35v QPI/Vtt Intel limit, within reason. More important is the difference or delta voltage to the rams Vdimm. This needs to be no more than 0.5v, typically with the 1.66v OcUK profiles. So a minimum of Vtt 1.2v allowing for fluctuations. Again keeping the QPI/Vtt fairly near to the Vcore is the key. Excessive deltas in voltage from one part of the cpu to another can generate heat (current flows with potential), increasing instability. Some uncores are better than others, often needing more QPI/Vtt with 12Gb ram and higher speeds.
