Hi guys, first post, so be nice :P

Just got the following for a higher end budget gaming system;

Antec 300 (value case)

Colors silent 750 watt psu (seemed a decent psu)

Phenom 2 x4 965 black ed, 125 watt, 3.4 (I like amd and this chip seemed to have a lot going for it)
Zalman 9500 (never done me wrong, dont like the drone on high rpm but it is such an open array in the antec 300 the top and rear exhaust fans help it a lot on low rpm)
ASRock M3A790GMH/128M (value board)
4gb ripjaw 2000mhz ddr3 (why not really :P )
running 9800gt (will be 5870 as soon as they stop making the boards out of rocking horse s%^t)
2x 500gb western digital, 1 os and programmes, 1 storage. (Will move both to storage once SSDs begin to hit mainstream properly)

Want to overclock once the 5870 is in, going for stable and nothing too extreme. As regards cooling, so long as my room is a reasonable temperature, I can have all fans on min and CPU goes at 38 max on low load, 47ish on high, so cooling wont be a problem I dont think- once everest alerts me it is at 50 just up the huge top exhaust fan and the zalman some. Should be better once I have offloaded the 9800 pumping 56 degree air into my case all the time.

Would like a few tips please;

1. Can I set the memory to 1600mhz safely- have already done a few start ups and everest benchmarks, it runs ok, good benefits, board and memory support it, will this be ok for the processor (supposed to be 1333 max)?

2. Can easily set the processor multiplier, will be looking for 3.7/8ghz, DO NOT want to mess with voltage too much, I ll leave that to the more experienced people. Can get it to boot and run fine, the processor should be 1.375v, cpuz says its 1.384v with OC and the same on stock settings. Will leaving voltage on auto cause any issues or should i fix it a value?

3. The graphics card is causing issues, it just plain runs too hot in a case that is well ventilated and a cool room it goes 80C+. Out of curiosity, will my having upgraded from a set up a step below the above mean the card has to do more work (it is the bottleneck) and so will run hotter- it has always run fine with me- my feeling is that a hot card is being made much hotter because it is outclassed by the system around it?

4. How safe is it to chance the reference clocks- with my current graphics card rather nervous about doing this...also do not want to fry the board, looking at sticking to +10% parameters- once a 5870 is in, will ten percent be ok? Does messing with ref clocks effect ram and gcard much?

Thanks in advance and much appreciated guys.
 
Your GFX card could be suffering from too much heat caused by build up of dirt. I had major issue with my old 7600GT getting choked with fluff and dirt. I never realised how bad it was till I took the card out in inspected it properly. The card cooling fins were almost totally filled with debris - after cleaning it out, my card was as good as new. It took me a good hour to strip the card and clean it, pushing & loosening fluff out with a thin strip of paper-card between the fins inside the heatsink fins (some I couldnt see down but tried to clear them the same way) and blowing the debris free.

I do this every 4-6 weeks now - air cooled systems need TLC!

Hit it with an air duster and a fair bit of crap came out, might just have to take it apart and see. Bloody dust who invented that??
