what voltage and clocks do you run for 24/7?

I think this g1 is ok aslong as you don't mess or move your pc around much,otherwise id plump for the perminant stuff

I might try for 1150/1500mhz now ive got some oc room

Various clocks.

1125/1575 - stock volts
1133/1633 - stock volts
1172/1667 - 1.138 volts
1200/1719 - 1.163 vols
1225/1750 - 1.193 volts
1250/1823 - 1.225 volts
 
Ok, someone asked what my VRM temps were as I used Akasa thermal tape to mount the heatsinks to them. I have just played an hour of BF3 on ultra at 1080p. I am happy to say the VRM's only went between 70 and 73 degrees. This is running my 7950 at 1060/1450 . The GPU only hit a max temp of 54 degrees. Only a few days ago it was hitting 75 degrees (even 86 when clogged with dust). I should add I have no fan blowing on them, and the accelero fans were running only at 70%.

I am super happy with the result, and pleased to have silence while I game !

PS just to add I have no intention of ever changing the VRM heatsinks ! Its good to know I can put the card quickly and easily back to stock when I sell it.

Excellent, thank you just what i wanted to see. How did you arrange the heatsinks? Did you follow the instructions that you got with the cooler or did you follow LtMatts picture a few pages ago?

I'll get a picture up tonight. I had a more difficult card layout tbh.
 
Id like to get my temps down as much as poss but i dont like the fact the chunky L shapers are a bit too close to other components. Ive got insulation tape there ready but it seems too risky
 
Here is my sapphire card's basic ram and vrm cooling !!

I have dual vrms but with two capacitors that move closer to the vrm's and chips between the vrms which stop the heat sinks sitting properly on the vrms. I had to use thermal pads so the heat sinks are higher than the chips between the vrms (you can see the x2 attached pads). I never took a photo of the finished product unfortunately.

I could only use right angled heat sinks on one side, and more basic straight ones on the other.

One other tip I would give is to use UHU glue instead of the sticky washers. Very thinly apply it, and blow on it to make it tacky. It's certainly easier than those ****ing sticky washers!

that's the same layout as my powercolor card

Its a bit more involved than the other layouts I have seen on this thread to be honest. The main problem is the beige chips which run in pairs between the VRM's. Because they are higher than the VRM's it makes using the adhesive impossible in my opinion (as you won't know if the heatsinks are contacting the VRM's properly). The only option is the akasa thermal tape with this layout. I should also point out the 4 VRM's on the other side of the card are squashed together quite a lot making heatsink choice difficult. In the end I used a spare RAM heatsink and a long one. All the above, as well as the two capacitors that crowd the VRM area makes it a more tricky install....but it is possible...and of course totally worth the effort.
 
I put the insulating tape between the gaps of the two rows of vrm's just to make sure as there's tiny resistors in between

The core temps now are fantastic,its not gone above 55c in Any game I play,max vrm temps I've seen are 77c on both,usually its around 63c

That's at 1150/1500 mhz,before the vrm's were 100-105c

That a reference 7950 v2 pcb. What's the mfr code ?
 
The rainforest site offered me RMA refund cos they have no more in stock. I said ill keep it and buy the parts i need they offered me £5 i ask for £10, i got £10. Just waiting on the parts now
