Hi, well I've only really had problems lately when I'm trying to render my 3D stuff (Cinema 4d, 3ds max) basically when the CPU is at full load, it wont hesitate to hit 95C! I'm currently using Liquid cooling: XSPC RS240 radiator and XSPC DUAL 750 BAY and the delta block. These temps end up in me bluescreening to a 124:

I've dropped to 195x19, and lowered my CPU voltage from 1.375 to 1.350. This isn't even slightly helping, I was originally at 3.8 ghz with 200x19 and 1.38125 but I've only had to go lower and lower, from my understanding with this kit I should be able to hit 4.2 without much problem.. any input I will be greatful for, this is really stopping me from working, getting blue screens while rendering is really annoying.

Ran Prime95 for 5 minutes, temps managed to get to 95C on the third core using 195x19 (3.7) and 1.35v
 
Something is up with your loop. I don't know enough about watercooling to help any more, but I'd probably want to take apart the loop and examine each component, something is definitely not right.
 
Oh dear something is very wrong here, all cpus are diff but 3.8ghz at 1.35vcore is prob the worst ever is the cpu a C0 chip by any chance?
A water cooling loop should excel at those speeds, list your parts and bios settings and we can try sort it out

error 124 is vtt voltage i think btw
 
Hi big, any help I can get to put this nightmare behind me is much much appreciated. You'll have to forgive my technical ignorance, but what is a C0 chip and how do I find out if it's what I have? This is from about 2 weeks ago: http://i52.tinypic.com/2l8gmd.jpg http://i54.tinypic.com/nduaev.jpg The things that have changed is, my ram is at 1531 and it's 195x19 with 1.35V IOH is now at 1.14V and ICH is at 1.2 (to fix the 4870x2 VGA Post problem) My specs;
Intel core i7 920
Asus P6T Deluxe
4870x2 2gb
1100watt Tagan PSU
12GB ddr3 G.Skill
Thermaltake Spedo
XSPC RS240 radiator and XSPC DUAL 750 BAY and the delta block

Thanks, again really would like to put this problem behind me.. I'd expect much better performance than I'm getting now with liquid cooling!
 
Sorry the i7 CPU's come in 2 steppings C0 & D0 the C0's need huge voltage 1.4+ to hit 4ghz where as the D0 chips can hit the same on silly less volts like 1.2-1.3.

Grab a quick screen shot with CPU-Z it will tell you what steping it is.

I really would suggest going back to basics on this one or you could be here all week trying to find the weak link. Reset everything to default run a very quick stress test 20min will do and see what the temps are and go from there IMO
 
And for the safety of your components try not to have your i7 go above 80* Celcius, tbh with a good water cooling loop you should be able to run that at 4ghz and never above 55*C. edit*(apologies 65-70)

The thing i would expect at first glance is that your cpu block isnt sat properly and is making poor contact with your cpu, if its not that then its your tubing is Kinked or your pump is too weak , thus not pumping enough fluid through your loop.

His pump is'nt to weak, its more powerfull then the one i use, and my temps never go over 70c (low rpm).

The never over 55c thing is wrong btw, for that you would need a really good clocking cpu and very low vcore, i would say most of the issues he is having would be related to a lot of the things on auto, and having to use a high vcore.

But it would be a good idea to see if the block is on properly, not to tight but not to loose either.
 
@necrontyr that's very optimistic seeing as my completely ott loop (420 rad for just my 920 D0) gets me in the mid 60's at 4GHz @ 1.25v with Prime95

I have to go with the badly seated theory though, or otherwise you may need to clean out your cpu block
 
Really, apologies im not a water cooler myself, i understand that water cooling will keep your temps stable far better than air, but i thought that most water cooling solutions meant that you start at 45 to 50 degs at idle and you shouldnt push past 65 deg at load,

So higher idle temps than air , but lower load temps... am i too far wrong ?
 
Generally my idle temps, are about on par with top end air cooling, can dip lower if the ambient room temp is low, thats the key thing the ambient room temp.

But yes water cooling comes into its own so to speak, once you load up the stuff you are cooling. So for example if i was to put a top end air cooler onto my cpu, with the same vcore, and load it up it would probably be 5c hotter (best) but generally 10/15c hotter, really depends on the air cooler really (silver arrow/DH14 being the best), and ofcourse air flow into the case.

Also something esle for the OP to check, is that the pump is getting power, recently i accidently knocked the molex connecter for my pump, and its stop getting power, did'nt notice untill i saw the temps, very high 90's, so as u can imagine i shut down and made sure pump power was connected again.

So a few things to check, pump is powered (water flow is key), cpu block is seated properly.
 
Hi bifday2k,

As we speak my idle temps are 45C... I'm pretty sure the power is connected, after I had re-dusted it today and when it powered on it made slushing noises for 1 minute (probably from being tilted sideways?) Again, forgive my ignorance.. but I've never even seated a CPU block, so can someone kindly tell me how I would check if it's seated properly? Is there anyway I can check if the water is flowing?

My idle temps are ranging from 36-42c, so your about right for the vcore you are using.

Is the res, fully filled, as the sloshing noise will be from the case being on its side, i get it when i do that, but very little as my res is totally full, if needs be run the loop with the cap off the top of the res, so any air can come out, may take abit of time.

The only way i test if my water is moving, without sticking my finger in the res that is, is gently cup your hand around a part of the tubing, and you will feel the water moving, its not like omg i can feel it, but u can notice it, over if the water is still, try this with the comp off, so no water moving, then try with the comp on and you wll see what i mean. Alternativly, turn all fans off and you should hear the pump, if u can't then thats the issue.

About the water block, its basicly plonk it down onto the cpu with tim on the cpu ofcourse, and and secure it down going from oppisite corner to oppisite corner, untill you feel some resistance, at that point it should be tight enough on. Don't over tighten though.
 
This might be a silly question but do you have fans mounted on your radiator? And at what speed?

And where it says revision is what it will be when others are asking if its C0 or DO.

And i personally would clean and re-apply thermal paste, but only u can decide if its needed, by looking. What i meant by reseating, is lossening it enough so u can move it abit, then re-tighten, that way u don't need to re-apply paste, if u remove fully, then yes would be best to re-apply. Depends on which way u do it.
