which way should i go for upgrading ? , i would like something that does not bottleneck my crossfired 5770's . my phenom II 720BE is just not got enough power/performance for my liking , but which way should i go ? . been looking at the fastest amd quad core , but that means upgrading my mobo also and my memory . not worked out how much i want to spend yet , yet again i do not want to spend a fortune either . it must last me a few years performance wise

what is your budget?
have you tried overclocking your 7200BE?
what MB adn RAM do you currently have?

1: not sure yet but some where around the £200 mark
2: yes it's running at 3.3ghz (fastest stable overclock)
3: biostar ta790gx 128m and Kingston HyperX 4GB (2x2GB) DDR2 8500C5

and the max my mobo supports is the phenom II 945

3.3GHz is pretty good although I'm sure 3.6GHz is waiting for you!

Is that a Straight Black-Edition overclock (i.e multi only) or have you tinkered with raising the HT link and NB speeds?

Crossfired 5770's must be quite nice :)
 
yes multi only and not tried anything else since it kept giving BSod's with the multi at x17 , and yes the crossfired 5770's are nice but they do not bench well in my system . one 5770 clocked at 900/1250 scores just over 9078 in vantage , but in crossfire they score only 11509 which seems poor to me for 2 5770 in crossfire . also they will not overclock in crossfire for some reason

For sure! :)

CPU MHz isn't everything, Fast northbridge, fast memory etc, all helps. Maybe worth leaving the CPU multi at stock and seeing if you can get some overclocking done without it, then when you have sussed out how far the IMC/CPU-NB can be pushed you can bring back the enhanced CPU multi.

How does your crossfired HD 5770's handle in games? What 3DMark score are other people getting with the same cards?

I can't see a +3GHz dual core holding you back that much?
 
dual core ? its a tri core lol , anyways in the reviews i read before i got the seccond 5770 they were getting around 60% increase plus . but the were running the i7 965 and i7 975 overclocked , as for performance in games it seems fine if i do not use aa . when aa is turned on at x2 i get stuttering in farcry2 and stalker cs + a few others
 
which settings ? , do you use aa in game ?

edit : mind you i have had stutter in games with aa turned on with my old 3870x2 and my 4870 512 and now with my 5770's , so it must be something wrong with something else in my system

have you tried resetting your system back to stock and testing?

There may be a chance something in the overclock is causing problems . . .worth a quick try? :)
 
had to set the mem speeds my self cause on auto it kept setting them to run at 800mhz and not 1066 , mem timings 5-5-5-15 and left the rest on auto . what should the multi for the ht and nb be set at ? , atm it is set to x10
 
10x Multi is standard for both HT-Link and NB as at stock they both should be 2GHz and the Ht Ref. is 200MHz (10x200MHz= 2GHz). You wanna how high you can raise the Ht ref (aka fsb) as that opens the possibility to overclock your NB.

Start by switching your memory back to standard DDR2-800, save, then change both HT-Link and NB to x8 multi, save, drop your CPU Multi down to 10, save, then see if you can get the HT-Link running at 266MHz . . .

If that works then you can try increase the multi on the NB, if you can make it back to 10x multi then the NB will be running at 2.66GHz which will help shift more data, also you may notice your memory is running back at DDR-1066.

You may need to manually increase the CPU-NB voltage from 1.1750v up to 1.25-1.30v to keep the NB stable once its overclocked . . .

These are just basic steps but if you can pull them off your overclock will be faster than just changing the CPU multi alone, a fast CPU needs a fast NB in order to shovel data about . . .

Let me know how you get on! :)
 
got it to 3.36 but it was not stable , so back to 3.3 :( . think i will go back to the old bios which seemed better to be honest , but that gave incorrect temps
 
no go on getting past 3.3ghz , and now thats not that stable when playing ra3 . think i will go full am3 of change to intel , this has to last me a good while but not cost the earth so am3 might be the cheapest way tbh
 
So you got this hardware right?

  • AMD Phenom II X3 Tri Core 720 Black Edition
  • Biostar TA790GX 128
  • Kingston HyperX 4GB (2x2GB) DDR2 8500C5 1066MHz Dual Channel
  • Radeon HD 5770 (Crossfired)
And so far the performance isn't good enough for your liking, even with the TriCore running at 3.3GHz?

something isn't right here, that's some solid kit you have? :confused:
