FX-8120 Gaming - 1 Core per CU - Rate my OC

post #1 of 6
Thread Starter 
I've been waiting for this for a while.
Gigabyte just released F6E Beta BIOS for the 990fxa-ud3. Although it STILL doesn't have LLC options, it sports some CPU management options I've been waiting for for sometime now. I love the "1 core per compute unit" option. You might be wondering why I would run the 8-core BD quad? Why I might as well have just gotten a phenom II X6 or X4? Well, I had a 1055t and could only run my 2000Mhz dominator GT's at 1333mhz. With bulldozer, I can actually get those ram speeds. And running 8 threads is a little useless for gaming. But BD's cores at 4.5Ghz are not all that bad compared to the phenoms.

Running 8 cores, my max OC was 4.3Ghz at 1.412v. My max temp running prime was 64C.

ONE QUESTION:
Should my temps be hotter running 4 cores rather than 8?

Now, running 4 cores, 1 per CU, I'm at 4.5Ghz (BIOS). CPU-Z reads 1.440v. It's stable. EDIT: Disabled System Smart Fan Control in BIOS, and push/pull config on COOLIT ECO is now syned.
I only play BF3 and skyrim and in both, my CPU peaks at 58C. Is this ok?

Max recomended temps, if I'm not rong: 61 celsius.

You are borderline, although still under the limit, I suppose.

Myself, I'd lower it to 4.4ghz and keep it there, just to be safe. But that would be your call.

Dont run the F6E bios, Its way worse then the F6C bios.
With the F6E I can only get a max of 4400mhz where on the F6C I can get 5ghz with the same voltages.
Both of them suffer from voltage raising tho compared to the F5 but atleast you can play steam games and disable APM with the F6 ones.

Hm. I'm running the F6 BIOS because I want 1 core in each module or compute unit to be getting all the resources and not sharing them with an integer core. I would have thought that this would raise my heat wall but it appears that it hasn't. Furthermore, I thought I'd be able to push it much higher than 4.5Ghz. Oh well. It performs nicely.

@Alex: EDIT: DISABLED System Smart Fan Control in BIOS, and push/pull config on COOLIT ECO is now syned. Before flashing my BIOS i had disabled it and forgot to do it again. Max temp is now 64C. So my heat wall is actually higher....

But still, 64C under small FFT's is over the limit. Would you sacrifice that for 4.5Ghz 24/7 clocks?

The max temp is the cores max temp of 61, On our boards the socket temp is really off. You can blow a fan on the back of it and it lowers the socket temp 6-8C.

64c for 4.5ghz, sure why not, its like its gonna burn or anything, silicon only damages near 100c.

Although it can cause instability.
