Installing a H100i - Fan direction question

azibux1 said:
I'm fairly sure the voltage is on auto... In short, what's the best way to work out a suitable voltage? Slowly lower it until you see issues? Then back up a tiny bit? But how do you find out where to start from?

Sorry for all the questions, I just went for a simple overclock when I did it by upping the multiplier

Just for info, currently typing this out I'm on 1.320v

Thanks for the tips too, couple more questions if you don't mind haha:

1. With regards to soaking the TIM tube, never done that before, I guess no water gets in if you stand the syringe face down in hot water, just make sure no water gets in the 'top' of the syringe (towards the handle)?

2. What do you mean by going the same direction as the die? I've never heard that term before so I'm not sure what the die is?

Thanks! :)

i think he means start just above the middle and put the tim in a down stroke manner not across.

Ahh okay

I used to use the pea blob method... Will try grain of rice from now as I think pea blob (or at least my application of it) is using more than necessary, and with TIM less is better (to a certain point of course :D ) haha

Also phate1337, with regards to the block orientation, I have the corsair logo the correct way up (pipes on the right hand side), which I'd hope is the correct way, :D
 
That is the correct way. The die is the printed part of the chip. It is a rectangle underneath the square heatsink. That voltage is high! I recommend starting at around 1.25 and working your way down (yes, it should be down from there!). By the way, the die goes in a vertical direction on this chip so that would be the best direction to lay your TIM. Stick the tube in a sandwich bag and seal it if you are worries about hot water getting in!
 
Thanks! I'm a bit busy at the moment but will change the TIM when I get a chance

Also will look at lowering the voltage soon then :)
 
if you want any screenshots of my bios of the 2500k, best to ask soon as i am selling the rig in a couple of weeks xD (a 5.2ghz 2500k apparently sells for around £200!)
 
Please do provide screenshots :D

I wasn't looking at going that high yet, but in future I may look at them

For now I'd just like around 4.3GHz maybe, I was happy with 4GHz as temps were getting too hot, but now I know the voltage is the cause of that I can hopefully sort it out and raise the overclock a bit
 
I will see if I can upload a few of my overclock profiles after I save them to usb. You can load them to see the settings but make sure you keep a good eye on your temps and such. Will grab my 4.2ghz OC profile for you next time I am in the office!
 
Great thanks! That 4.2 will be the one I'd most like please as that's closest to my target

So when it is on Auto the voltage goes up and down presumably, surely when you enter a fixed value, are you not running at a higher than necessary voltage at some points?
 
I tend to use offset voltage and leave speedstep and all of the c states enabled for power saving. Usually I will use fixed voltage to see what is actually required for it to be stable at load and then move from there to offset by matching the load voltage. Can be tricky but defo worth it! Start with 42 multi and 1.25v and check for stability using ibt, occt and if it passes those, bump the multi up to 43 and retest. If it passes great! If not bump up your voltage slightly and then rerun. Once you have occt stable for around 15 mins and 10 passes of ibt using max memory then you can look at reducing voltage if you did not have to up it to get 4.3. Once you are happy there and stable on the above, run prime overnight. If it passes, roll with it. This process will ensure stability 99.99% of the time but you may find that you have bluescreens doing something normal like browsing the Web. If you do, up the voltage! Really really handy tool for me was the overclockers bluescreens guide [URL="http://forums.overclockers.co.uk/showthread.php?t=18482850"]http://forums.overclockers.co.uk/showthread.php?t=18482850[/URL]
 
Thanks for all the details and the link!

Will definitely look into this when I have more time to test it.

For now, rather than leaving it as it is, would you say I'd be better off setting my voltage to 1.25 with the multi on 40? Just as something that will definitely work without issues as I need my PC at the moment, or would I be better off just running with the slightly higher temps?

Will/can you ever end up in a state where you can't even get back to your BIOS to fix this if you mess it up? My guess is no?
 
Well if you take out power cable and bios battery for like 10 mins it will reset to factory default so you should be fine. Just stick it at 1.25v and if it works, run with it. If not stick it back on auto until you have time to play with it!
 
When you have applied your manual voltage, let us know temps? Also if you wanna continue discussing the overclocking I will happily stay for the chat until you get it where you want it but I think if you do we should make a thread in the right section of the forums xD
