A new CPU or a new GPU? Help, suggestions? - Page 4

post #31 of 40
Have you stressed it long enough on prime? 12 hours minimum? Your OC obviously isn't stable.
This is your heatsink btw. thumb.gif

Either you have a bum chip or doing it wrong,maybe RAM freq/timings are off?
Thuban OC range is from 3.9-4.2 with that chip.
Also could be the BIOS you're running.If you have close to the latest..try an older one.
No need to run Prime95 for hours and hours doh.gif
Download Hyper-pi and do 2 runs of 32m.Ackk..on AMD..it'll take about 40 mins puke.gif
For real quick..3 runs of IBT.
Even the maker of IBT said he wouldn't do more than 5 runs..It stresses too much.
IBT=Intel Burn Test.
I would really hate to see you get an FX chip thinking it would be better for gaming and realizing that it's not.

You could very well simply have a bad oc'er on your hands. I've been in cases owning the same model cpu and got only a 300mhz oc on one, and a 800mhz on the other, truly the luck of the draw. If you drop it down to 3.4ghz, is it stable?

If you truly do have a bum chip, your best bet is by far getting an 8350

I'll be honest, I couldn't even get my AM2 7750 Black Edition to overclock and they're supposed to be beasts! Or were back in the day!

I'll have a play around later and keep you posted on the results.

Ok. Maybe so. Now assuming he's just as lucky with that 8350 and gets it to 4.8-5ghz... bye bye thuban.
Why game on a maybe? The 8350 is the clear upgrade path in this case.


Hmmm no, a Thuban to 4 Ghz it's on par with a Fx to 4,6/4,7 ghz, IPC on Thuban is about 15/20% better.

You need a piledriver to 4,8 Ghz to match IPC on my Thuban to 4,15 Ghz,

Ok. Explain this.

http://www.tomshardware.com/reviews/fx-8350-vishera-review,3328-14.html

So a 3.3ghz Thuban is roughly 10fps behind on average to the 8350 on a very lightly threaded game. So you are telling me that if we add 700mhz to the thuban (4ghz) and add 700mhz to the 8350 (4.7ghz) that it will not only close the 10fps gap, but also match the 8350 @ 4.7ghz? I find that really hard to believe.

Especially considering the x4 980 @ 3.7ghz is still roughly 5fps slower on average than the 8350. Adding 300mhz to the x4 will probably close the gap a bit more, but unless the thuban architecture is some micracle one (compared to the deneb )that I'm not aware of, it's not going to touch a 4.7ghz+ PD cored FX.

Now if he can actually get a decent overclock on his thuban, than no, it's not worth the upgrade IMO. However, if he truly has a dud or just cant get a decent OC for whatever reason, he is by far better off getting an 8350

Its very simple, overcloking NB, something that gives almost, if not the same gain in perfomance that only rise CPU clock, at least on Phenom II

here an example with a very CPu dependent game, and very lightly thread game, gain 8 fps rising NB 800Mhz

http://www.overclock.net/g/i/1115103/a/802638/sort/display_order/


here to 4Ghz and NB to 3Ghz, 23 fps over stock

http://www.overclock.net/g/i/1115097/a/802638/sort/display_order/


And for the clock if Thuban have better IPC dont need to be so fast as piledriver to do the same

Thats my case, i was waiting to see piledriver but isn't worth it for me, fantastic CPU anyway

I say get the 7950. A friend of mine recently dropped in a 7950 into a bone stock Phenom II X4 965 and its seams to pump out FPS just fine. Really people massively over estimate the need for CPU power. Yes there are games that need a fast CPU but the was majority are GPU hungry and can run on very modest CPU's.

Valid point, I tend to forgot the NB oc'ing on those as I've never owned a phenom based cpu, just a bulldozer 8120 (meh, but was still a huge upgrade over my old x2 4200+ s939 system). Haven't had a need to OC my 8350 yet though for the games I play, but I'm sure the day will come.
