*** Official AMD Phenom II X6 1055T & 1090T Overclocking Thread ***

Whats in the loop 1st? Does your system go

Rad > CPU > 4870x2 ?

Surely prime won't make your GPU get hot anyway?
Does your temp rise above 46c after more than an hour of Prime95?
 
My loop goes Res/Pump -> CPU -> 120mm -> GPU -> 240mm -> Res/Pump.

No GPU shouldn't affect a prime run much, but may affect idle temps more. well, that's the way it works in my logic :)

To be honest I've not run Prime95 for much more than an hour yet. The trouble is the system is built around an OcUK pre-overclocked bundle (@ 3.8GHz). When I originally got it I ran prime and the motherboard caught fire (yes, with water-cooling :rolleyes:). I got it RMA'd but have been nervous with the new system in case there's an inherent fault with the motherboard (which I doubt, or why would OcUK use it?) or something.
 
Any reason why your pipes go from 120 > 240 ? Not done watercooling for a while, so not a criticism ;)
 
Mostly inexperience and the inability to get it into my head that the order doesn't really matter. In my head the CPU would kick out less heat than the 2 GPUs so I put the 120mm rad after the cpu to cool the water after that and then the 240mm after the graphics card as I thought 4870x2s ran hotter so needed more cooling.

If I did it again I'd probably try to just do the shortest loop and ignore the order.
 
These look quite interesting, but I'm not sure what motherboard is best value : overclock - I've heard the Crosshair IV is the best (but its ~£250) so tad too expensive for me lol.

Looking for any other motherboard, mATX if possible but if that affects the o/c (mATX) then whats the best ATX?

Thanks

Did a 5 hour run of Prime95 last night. Temperatures were cooler because of ambient I guess. this time it didn't go over 43C. I think it hit about 41C within the first hour, so doesn't seem to be a lot of fluctuation over time.
My GPU temp did go up too, to about 40C as I recall (from 36C) but I guess this is because the water flowing through the block is warmer.
 
4 ghz 250*16 1.425V CPU NB 2.6Ghz 1.225V
IBT 20pass ok, 5hours Prime ok
temps on load 50 max
can't be bothered to oc higher...not worth it

^ entirely depends on what you use the computer for

have you tried unlocking the x2? could get some free performance :D

yeah have tried.

well use it for gaming and uni work mainly so not sure if i should flog it in an auction and get one of these or possibly the 955
