GTX 680.

I think anyone wanting monstrously raw performance should just save up for a 3930K, I just like playing new stuff mostly.

3930k is expensive but is probably the least disappointing cpu available

quite impressed with piledriver the cinebench results show promise , i'd certainly consider one around xmas if I have some spare money to replace my x4. For the money it would make a very attractive rendering machine. Would it be better single threaded than my x4 @4.2 ghz I wonder.

Resized my shizzle.

Ah... Wolvers... da'man! Nice results

Do you have Metro 2033? RE: http://forums.overclockers.co.uk/showthread.php?t=18456815

Yeah, but I'll have to install it. I could do that tomorrow, PM to remind me. It's late and I'm old and tired.

Running at 4.7 now, 200x23, just squeeezed over 8pts in Cinebench.

Working on stability now. There's more to come from this though, I get better scores with a lower multi and higher fsb. Also I haven't started on tweaking this 30nm RAM yet, it's good for much higher higher clocks or tighter timings.

What was the decision on CPU temps to watch? I'm hitting 61C on the CPU temp in the Asus software and 55C in coretemp while running IBT. Have I got any more head room?

humbug · 4 Nov 2012 at 02:32

^^^^^ 68 on the CPU and 58 on the cores might be ok. or it might now, try it. Mine crashes at 56c cores but i have seen FX CPU run warmer

my core temps is totaly buggered. says my cpus ide temps are 15C.

worked out it was 20C out.

Once mine hits 45C which is really 65C it starts to throttle the cpu down.

wolvers · 4 Nov 2012 at 10:26

It looks like my core temps are reading OK under load, but not at idle as everyone says. They've not gone over 58c yet, but I have seen 66c on the CPU temp which I think is the socket?

Currently stress testing 4.8ghz. What's your PLL voltage (also called VDDA)? I've got that at just under 2.7v and it's helped me get a higher clock without loads more core.

Edit; Woot! 20 run IBT stable @4.8ghz.

Before getting too excited try 30 mins of P95, then you will see the temps climb.
Also IBT should be run at high as a minimum, standard does very small tests and doesn't provide much load.

I would say you've gota thermal issue there look at the cpu-z

X7 multiplyer its downclocked itself

Martini1991 · 4 Nov 2012 at 11:59

The results are abysmal too on the Gflops.
Unless it's a mistake, that's throttled.

its deffo down clocked.

I can get well over 5.0 ghz if that didn't matter.

Mines stable now @ 4.3ghz at 1.30v no throttling happens if I go over that by much it throttles every now and again.

Martini1991 · 4 Nov 2012 at 12:03

It's why I made a fuss about the temperatures and the inaccuracy, much simpler to ignore temperatures and just monitor if it's stable without throttling.

Thanks for the stress testing lesson.

It took me a couple of hours to get it that stable at 4.8, so I'm working on pushing it harder now. I think my cooling is going to stop me from getting there though. I'll probably end up with 4.6 or 4.7ghz 24/7.

It's just downclocked after the test has finished, with no load on it.

Martini1991 · 4 Nov 2012 at 12:04

But those Gflops?
They're not normal.

yeh.

I've noticed if my core temp gos over 40C then it starts to throttle for 1 / 2 secs every minute

It's normal. 4.6ghz example.

hes right. I just ran it at 4.3 and got 40.5 gflops

passey89 · 4 Nov 2012 at 12:13

a 2600k @ 5.2 scores around 66 / 70

No thats normal
The 8150 struggles to get 40Gflops at 4.6Ghz
The 83x chips are a bit better, but not a lot. 10% or so

The FPU units of which there are only 4, are weak sauce i'm afraid.
