3820 have limited unlocked multiplier x39 - x43. With multiplier alone, you can overlocked to 4.3GHz. Using STRAP, you can get higher. I didn't really push on OC because lack of better cooling.
Congrats on the water cooling kit. It feels like it's been forever since I started out in water cooling.

**First OMG sorry this post turned out so long.. got carried away.**

Well its been a few days... and my system is still stable, not a single BSOD... there is however one thing still annoying me.

First I should mention this has been happening ever since I got the new motherboard and cpu, and before I even thought about overclocking my pricey new gear.

Sometimes (random) when I shutdown the pc, windows7 will get stuck at the shutting down screen, the keyboard turns off (g110 with lit keys- so its easy to tell when power is cut). However it just sits at that screen with the text saying shutting down and the spinning circle, so the system is not locking up.... no matter how long I wait it just stays there so I have to hold the power button in for a few seconds to turn off the machine.

After this happens the next time I turn on the pc, it will stay black-screened for about 10 seconds before shutting itself off, and turning itself back on about 5 seconds later, then shows a message "overclocking has failed" or something like that and tells me to press F1 to enter setup, After entering setup I just press F10 to save and reboot and everything is fine again until it decides to happen again.

I have run prime over 24 hours stable along with memtest and intel burn test.. Playing games for hours, watching bluerays, recording game footage at 1920x1080 with fraps and encoding to h.264/mp4, this machine does it all rock solid, yet this error will not seem to go away.

My board is a Asus p9x79 (not pro or deluxe), I have tried BIOS updates thinking they would solve the problem, 1203 and now 2002, however its still there.

I seriously doubt this is an overclocking issue, however feel free to mention something/anything that might help... Maybe its a bug that needs to be fixed in a future BIOS, I hope that's all it is.

I have read about lots of people with the same issue, so in a way that is looking good for me lol "if it gets fixed".

Moving on....

Over the past couple days I re-seated my heatsink (Thermalright Ultra-120 Extreme *for anyone interested*), it took a few tries, before I was happy with the results, all cores can now get below 30c at times during idle, lowest before was 30c and that's before overclocking (same ambient temp), never in 20's... one core really likes to stay frosty getting as cold as 24c.

Idle temps:
29c-24c-28c-29c

load temps:
70c-65c-66c-69c

temps never go over 60c while gaming, heck not even sure if they get over 50c now that I think about it.

I used ArcticSilver5, overall I tried 7 times before I found the best method of application that worked for me.. the pea-size / rice-size blob method is what I kept using however the temps did not seem right, I was making sure the heat-sink went on flat and not at an angle... yet each time I noticed the compound did not tend to spread evenly, or thin enough when I removed the heat-sink.

This is first time I have ever used this method, and I must say I will forever be using this method from now on. Put a small rice size blob (VERY SMALL) right on the center of the cpu, get some glad/cling/plastic-wrap (whatever its called over there - the stuff you use to cover food plates with in the fridge), and wrap it around your finger keeping it tight/smooth.

Then spread the compound in a circular motion with your finger starting from the center and work the circle out till its covering a large enough area of the cpu but while keeping a good clearing from the tiny hole on the cpu.

When the circle is done, the compound should be so thin, that just touching it gently with your finger will remove a bit of compound exposing the shiny cpu beneath, just gently try to smudge it back over. check if any more cpu is showing through before putting on the heatsink.

Shouldn't spread anymore due to being so thin.

Moving on....

Even turning up my gtx-680's fan from stock/auto to 70% brings its temp down from 32c idle to 24c, and from 81c highest I have seen it down to 67c highest while gaming.

Due to increasing the fan speed on the gtx-680 (hardly any extra noise btw... guess my pc fans drown it out), my 3dmark11 scores even jumped by a decent amount.

I just did some tests and here are the results.

GTX-680 Inno3d.

(max cpu temps during tests were 57c-53c-56c-56c)

Stock settings:
Bench1 - 9995 score - max temp 76c
Bench2 - 9900 score - max temp 77c
Bench3 - 9886 score - max temp 78c

Fan speed increased to 70%:
Bench1 - 10067 score - max temp 59c
Bench2 - 10058 score - max temp 60c
Bench3 - 10058 score - max temp 60c

Fan 70% + OC core +100 mem +400:
Bench1 - 11342 score - max temp 66c
Bench2 - 11333 score - max temp 66c
Bench3 - 11349 score - max temp 66c

After some research I found out that the gtx680 underclocks itself once it reaches 70c as some sort of precaution, no clue why as this card is rated to run at temps much hotter than 70c.

So if anyone reading this has a gtx680, I recommend at least turning up your fan speed, the default is only about 30%, and you can see the temps drop dramatically.

Even though the temps are in control, I cannot overclock the cards base or memory any further without the driver crashing in 3dmark

If you key in a manual voltage, you will not be able to enable the power saving features that drop the voltage along with the Speedstep.
I am unsure which memory you are using, but there should be different values available depending on your Blck and strap. You could a couple of things:
- You can select the closest value below your rated RAM speed.
- You can select the closest value above your RAM speed (< 200Mhz), and see if you can get it to run.
- You can select the closest value above your RAM speed (< 200Mhz), and see if you can get it to run with a slight voltage bump.
- You can select the closest value above your RAM speed (< 200Mhz), and see if you can get it to run with a slight voltage bump, and increase the timing values by 1.
Below are screenshots of my BIOS settings, They may not make your system stable, but that should provide a good idea of what you should try experimenting with.
Good Luck! cheers.gif







Hey man, thanks for your help.


I did everything like you suggested and got these results:

1344088995-clip-489kb.jpg


How do they look? The vcore jumps to 1.37V and it seems a bit high to me for a 4.6Ghz OC. Maybe there is a way to lower it a bit?

The best way to do that, would be to lower your CPU VCORE Offset Voltage. Then run prime95 Large FFT's for 1 mins, if you don't get a BSOD then lower the offset some more. repeat until you get a BSOD within 20 seconds to a minute. then raise your offset a notch and then let prime run for as long as you can, 12+ hours is good. if you get a BSOD again, just raise the offset another notch and repeat.

you can also change from offset to manual and put in the voltage you want to try directly.

The offset I use now is 0.060 Should I try something like 0.050 ?

Also, how do the RAM timings look to you? What do you think could be tightened? I'm using This Corsair kit (9-11-10-27 , 2133Mhz at 1.5V)

Thanks Scrapy

Yeah, maybe even 0.040, or lower still.... the idea is to find the sweet spot for your chip, some take more voltage than others.... just do what I said, lower it by 0.010/0.005 each time until prime95 gives you a BSOD while running Large FFT's, the BSOD should happen within 1 minute... so keep lowering your voltage until that happens. When it does give you the BSOD, go back and raise your voltage by 0.005 and try again, if it does not BSOD then..... leave it running until it does... could take acouple hours after that before it BSOD's, but if it lasts 12+ hours.. you should be all good.

as for the RAM timings, I'm not the person to ask because I really have no idea myself... currently using triple channel memory and in need of an upgrade in that department, so I have some research to do so I can work out what I should get.

BTW I should mention.....

My current overclock is:
4.5ghz
125 STRAP/BCLK
x36 Multi
vCore 1.325v

Being on the 125 STRAP/BCLK also increases your (QPI Link in CPU-Z), mine is at 5ghz, this I believe speeds up the pc in general a considerable amount... at least from what I have noticed its quicker than 4.5ghz at the 100 STRAP/BCLK which is like 3ghz

Also using less of a vCore than you... If you feel like it, give the 125x36 a shot... you should be able to leave all other settings as is, just remember to write down anything you do change so if it does not work for you, you can revert back.

*EDIT* (more info, and corrections)
just incase you would rather not lower your overclock speed....
125x37 = 4.625mhz

Also, make sure your RAM timings/command rate/voltage reflect using the boot strap, you will end up with a different RAM speed that you were at 100mhz. My RAM hates running above 1600mhz and I had to add .050v to get it to run at 1666mhz (125mhz strap).

lol didn't read the full post did you? or at least the top part that explains what happens...

anyway its not a cold boot issue, I'm almost 100% sure its a BIOS issue/bug... only happens when windows7 randomly wont complete the shutdown process. apart from that, everything so far is 100% stable.

and my voltages are manual, I do not use offset.

However your idea about the boot vCore might be worth looking into, thanks.

*EDIT*
BTW, might be a wall... but at least it has holes wink.gif lol

I did read the full post, its confusing as hell and you were talking to the other guy about using offset mode so I assumed you were as well since you did not list any voltages. Next time be a little more specific. thumb.gif

I also had the issue of windows hanging on shutdown with the mouse and keyboard shutting off when I switched to 2002 but I switched back to the prior BIOS already because of that turbo issue I was having and it seems to be fine. I ended up hitting the restart button every time because it would take the machine 20 minutes to shut off on its own, so you're right about that probably being a BIOS bug.
