E8400 OC with water cooling.

post #1 of 11
Thread Starter 
Hey Overclock.net

Im trying to OC my sig rig some more.
I've just bought the XSPC Rasa 750 RX360 CPU watercooling kit. But even with this cooling i cant get it over 4.15GHz? in BIOS my vcore is set to 1.4, and when im running prime i get temps around 68C. if i raise the FSB i get a error on on of the cores, and if i then raise the vcore it gets too hot. Is this normal or am i doing something wrong?

A picture from cpu-z is included, and i hope someone can help me getting this a little higher, or atleast telling me that this is normal

thanks in advance.

Your temps seem high to me, My E8500 did 58c at 4.275GHz with 1.36volts with a d14 CPU Cooler. I would expect your kit to manage lower temps.

Here is what I would do to eliminate the issues you have. Keep all the voltage the same and then lower your multiplier all the way down to 6x. It will give you 460x6 = 2760mhz. Now raise your FSB by 5-10mhz increment and see if you can get it stable. Let say you crash at 500mhz FSB then very likely you need more voltage on the north bridge and maybe a fan to cool it down. If you can hit 500mhz FSB without any issue, then the next thing I suspect would be your E8400 needs more vcore, due to the fact it has older C0 stepping.

by keeping all the voltage the same you mean stock voltage right?

Keep all your voltage the same you have right now (not stock), cpu vcore = 1.4v... etc...

I am not surprised at that temp on 1.4 volts, that is probably higher than you need.
What is the ambient when you get these temps? You probably need more on the NB but may need to add a fan to it if it doesn't have one already, make sure it stays under 60c.
Also what is your FSB termination voltage?

Theres no fan directly on the nb, but i have the haf932 which have a 23cm fan on the sidepanel blowing air on the motherboard, so im hoping that it will do the trick. but where can i see the nb temp? is that the one called system in speedfan?

and okay, ill try lowering the multiplier to 6 and see what happens

everest should show the NB temps

However how hot is "too hot"? I would expect <60C with a rx360 on an e8400. 1.4V isn't that much for a dual core no HT 45nm under water. What TIM are you using? Did you try remounting the block?

What's your memory speed? It could be your memory interface becoming unstable as you raise the FSB

so i just downloaded everest, but when i went to the chipset tap a windows alert poped up saying that everest was trying to install a unvalid driver, and it wasnt allowed with this version of windows, and theres nothing in chipset, motherboard or SPD.

and no i havnt remounted the block, but would that make a difference? i mean i cant mount it any other way then i did?

and in my opinion it is too hot when it gets over 70, at least thats the max temp i wanna go to.

my memory is running at about 1550mhz (cant remember the actual speed) but i lowered it because else the system wouldnt boot.

at last i dont know what TIM is, but if you can explain ill tell you what i use

TIM = Thermal Paste/Compound
