So I am running a q9650 exteme, kept this chip for a while sold off a few i7 systems i had and kept this baby just love my set up don't plan on upgrading my computer until i can get an 8-core cpu, I mostly do daily netting and programming on my desktop. Play some games two but my crossfire 4850 crunches out cyrsis at ultra hi around 40fps so i have no gaming gripes. Just wish i could find a volt mod that worked with my damn non refrence cards so i would have a reason to water cool those puppies too.

Anyways i like to Over-Clock for for fun nice to see chrome open instantly and windows 7 boot lighting fast! Also love beating my own benching if i had money to spend id love to do real benching competitions. Anyways i lost all my oc setting along time ago but i remember i had a hard time getting to 4ghz back then too.

Recently i set up an insane water external water cooling loop that is cpu only! But I am still sanded by my results. Here is a picture of the loop, I hope its not confusing tried to make it neat as possible with paint and cell phone pictures, two lazy to install photoshop since im going to reformat again once i get my max daily OC.

And here is a picture of my results, I am going to go ahead and post the link to the screen shot it is to big to post here with out being rude and it still being readable. Screen shot of allot of junk running! (http://i104.photobucket.com/albums/m195/boorishid/screencap.jpg) Ok first of all when you look at Real-Temp it says my max temps, those were while running Intel Burn in Lin-pack testing, there in the 70s (don't really like that). The current temperature Real-Temp is showing is while doing Small FTT's in prime 95, I am assuming those are allot closer to real life scenarios right? I idle in the low 40's and my ambient is somewhere between 70-75f maybe even 80f. Do these temps seem fine for everyday use on a 45nm chip?

Im actually trying to push to about 4.2 to 4.4 dunno if ill get there. My vcore is at 1.392 (intel recommends 1.362vcore i believe wondering how much i can really push it for a daily) with LLC turned on, the only other voltage ive touched in my MCH(North Bridge) Haven't messed with any of the the PLL, Term Voltages, or Reference voltages. Don't really understand them to much, i think everything else is on auto. Basically i stared out with a multiplier of 6 and ramped my fsb up to 500mhz while keeping the ram locked into to stock settings, and kept stability testing with Burn it and prime for about 12 hour sessions till i found the right voltage. MCH is 1.26. Im thinking of maxing the vcore at 1.45 to hit my goal is this going to be safe with my cooling, is reverse migration gonna dump my cpu down to one year running it that hi most likely?

btw some of the stuff twords the wall that looks like hosing is acually wire wrap

Anyways this is far from 100% stability tested but its the closest ive gotten so far will do more testing and tweaking later. I really want to hit 4.3 at least what is the max core temps i should hit safely 75 and would those temps
be better off being read from the linpack test or prime95?

One more question i wasnt seeing any temp diff whats so ever with the deltas on the bonnie core at 3.6 but would it make a difference to maybe put them back on at these hi of voltages? And how about lapping my cpu, i use to do this but didnt wanna ruin the warranty on the qx9650 (think im over it now though), Ive heard you should not lap these Apogee GTX water block right, because they are bowed to touch the all four cores of the cpu in the perfect way?

having had more wc`ing options than I knew what to do with at the time ive created some over complicated loops to no avail :)

I would remove small rad, small res and shorten the tubing some.
unsure about the pumps does one alone produce enough flow if you were to alter the setup?

more volume of coolant wont help... ive tried as much as you would find in the average 1.5 ton van just more costly to fill about sums the result.

im hitting 4050GHz on two triples and cooling CPU, NB, GPU.
(maybe im cheating slightly by living in the uk?)

Had more luck with 9.5x multi 450bus myself.

anyhow im no guru but its quiet out :)

hears the link to my transformation from overkill to a much simpler setup.

EDIT: maybe alter thoes triples to both push and make sure there not feeding air flow from one to the other as well.

another thing I notice is the 8gig `o ram

I managed to get 8gig running myself but two of thoes sticks (matched pair) toasted through the abuse.

much easier to clock 4gig and little performance drop really.

if there matched pairs then you will need to loosen the timings a little to get all 4 sticks something like with the cpu clocked anyway in my experience.

So you need to lower temps but didn't tell us what your temps are? I guess with that setup they are about as low as they can be with water.

Bobby, sorry dbl posted the other wasnt complete, but in my defense o your other replies.

Shorting the hoses shouldnt matter i should have plenty of head pressure with those two pumps in series and the length of hose.

As far as the second as the second res its not about volume i know the temps will even out, its more there for convience of filling he loop and i have a long hose hanging off the back capped off so its very easy to drain the whole thing lol.

8 gigs of ram are installed becuase i live o run Virtual machines!! :) Im running the ram stock speed stock timing though haven even tried to tweak it. The only thing is my latch is 333 instead of 400. Just had to bump up the vcore to 1.4 blegh. The third rad is there for a future ideaa of making a custom water block to cool five or 6 teks on it. dont think its doing much harm with all that head pressure, maybe im wrong...

Im thinking the best way to get the core lower is to mess with the PLL TERM and REF voltages because im only having one core fail at 3.92 in prime and it seems to linpack fine. Just scared of to much voltage and wanna shave off any temperature i can by lapping or adding fans on that rad if itll help at these higher voltages.

btw some of the stuff twords the wall that looks like black hose is acually wire wrap

I wish these gigabyte ep 45 boards would give me temp reading for my nb and in everest maybe i just need a bios update and a new version?

The reason im shooting at i 500mhz bus with an 8 multi even though i have an extreme is becuase im under the assumption a faster bus will give overall better performance ive done the 9.5 multi in the past but im really shooting for as fast as i can.

you need this version and im running bios F8 (modded:sly:)
78327

my northbridge is under abuse at 1.320 currently... in the middle of some new gpu driver action. its normal for it to be 3-5`c cooler :rolleyes:

as for your setup as conundrum and myself feel its plenty and as good as water will get you a result.

maybe if you want to explore that cpu more its time for extreme measures :shrug:

lapping the cpu is more danger and effort than I would go to for water.

and yes ive read myself the gtx block doesnt fancy being flattened.

whats the vid of this cpu?

ok guys heres the skinny i did post the temps in that screen shot but they weren't stable at 4ghz yet, now they are, im running 1.26 mch and cpuz reports 1.392 volts with LLC enabled in the bios the vcore is set to like 1.45 or something nuts. Everesr reports the dimm volts are 1.92 and the CPU VID is 1.25 (btw what is VID?)

For those of you not looking at the screeny i posted the current temps in an 80f ambient with prime95 small ftts are 63-63-62-62

Under Intel Burn Lipack temps gets too, 64,46,63,63 not as huge of a diffrence before but i just turned my heater off lol to damn hot

So version 5.30.1900 is the everest version, what do you mean a 'modded' f8 bios? i dunno what version im running ill check lol will that wipe out all my save bios profiles. So your core temps are all right? i hate using care temp and everest.

The VID is the "stock" vCore for each chip, and it varies from chip to chip based on Intel's testing procedures. The VID will tell the motherboard: "This is the voltage I require at stock speeds when the VCore setting is on 'Auto' for proper operation.
lower VID value will yield better overclocks on average.

yep my temps are what they are at idle.

my vid is around 1.32 (rubbish)
currently clocks to 4050 with 1.34vcore (actual) about 1.38750 in bios (I think)

the modded F8 bios im running isnt really relevant to clocking :sly:

well i would start with push pull on the rads and not have one blow into the the other, even though there is space one is still sucking in warmed air.
