DUMO: awesome winrar! Keep push- 6000Kb/s will be done !

I managed to dial in a short/test of Prime blend at 4.6GHz today. My chip may require more vcore for clocks than a few others that I've seen but it may also be a little cooler running? Load temps were usually running in the mid to upper 40's C. with peaks sometimes as high as 50/51 C. Ambient at ~21 C. Cooling: TR Archon with push/pull. (Disregard the CoreTemp 225x20 4.5Ghz because I forgot to close and reopen it after using TurboV Evo to bump up the clock to 230x20 4.6Ghz)

I suggest using HWMonitor or other software which can read the "motherboard specific" CPU sensor.
The temperature read by the internal sensor is not the actual die temperature (tCTL). The value displayed by CoreTemp etc. (tCTL) is atleast 10-15c lower than the actual die temperature is. During Prime95 LargeFFT the tCTL temperature reading was 43c while my Fluke IR thermometer showed 52c measured from the side of the IHS. The motherboard CPU sensor displayed 55c which should be quite right.

Used an offset off 14°C for the testing with the FX cooling kit( CPU idles then at +/- 28°C). At 4.8 prime 95 I get close to 87°C, the heat coming out of the back of the case is huge... 4.5-4.8 will be the sweetspot for many, 5Ghz might be too much for all in one liquid solutions and air coolers. ( not talking about a pi/cinebench run )

I wished AMD got their sensors right as idling at 14°C seems a bit silly... load at 45°C, when the room heats up drastically...

That is kind of a bummer!

I noticed that the Turbo EVO temps were running ~10 C. higher. Now I'll need better cooling or reduced clocks... I'm not sure running/crunching ~4.6GHz 8-cores load 24/7 at ~ 50+ C. would be ideal for the chip? What kind of daily (load) temp range do you all think I should shoot for?

I would not worry about the temperatures until they are 70c+.
These chips are rated to 90c (thermal control, "throttling").

Bios 9913

Catalyst 11.9 kept givin' problem for crossfire setup

[img]edit[/img]

do you prefer 9913 over 9911? Is there a link anywhere for 9913?

I'm still playing with 9911 and will try 3Ds with 9913 again next

Heres core temp K15 from The Coolest, I haven't try it with ambient temp. though.
Will ask The Coolest for dl link

I wanted to test SLI on the board yesterday ( 9911 bios ) First did some runs with the 1090T@4ghz and then popped in the FX 8150@4.6. Outcome all 3D scores dropped ???? CPU score is everywhere higher, yet the GPUs seem to get limited somehow (or don't scale as much as with the 1090T) ... Reinstalled windows ( Ghost image ) tried other drivers, no go... will try 9913 and in the end pop in the 1090T again.

Have I just been Buldozzered ?

[Dumo]

Vantage cpu test 1 sometimes dropped to >1000

Heres 32m

[mav2000]

Nice voltages for a 5 Ghz run....are the CPU Z tabs right?

[Dumo]

Yep, AI suite bouncing around 5009~50018 under load

@Dumo

Even though chew* said low VID chips didn't scale as well when going "cold" as some that had higher VID... it looks like they still might be better clockers with ambient air/water? I know you are running SS but on air my chip is running ~ 400MHz lower with the same vcore.

It seems like it PR.

I'm still trying to find oc settings that balanced my old SS capability (1.5+ Vcore 8C/8T is too much).

Really like playing with BD but 2700K is waiting. Lol

[The Stilt]

For air, water (+chiller) and mild phase a chip with average leak & VID seems to be best.
There are quite massive differences between the power consumption (= heat) between the keepers & leakers.
The least leaky chip (happens to have the highest VID too...) I got has over 10% lower power draw than the one which has the highest leakage (lowest VID...).

The chip with lower leakage does better on air with 4CU/8C configuration, while the high leaker beats it hands down with only one core enabled. The "keeper" also runs 6c cooler at the same clocks, even the VDD is 0.1V higher.

Thanks for the comment.

From what you've said then I gather Dumo's 1.200 VID chip might well be too HOT (power hungry) when attempting to run on air at ~4.6GHz(+) 8-cores as compared to my 1.287 VID sample with a similar o.c. and a higher VDD...

From your experience and from the samples that you've tested... what range or ~ number would you describe as the ideal average leak/VID? A chip(s) that would hopefully offer the best balance of clocks to lowish voltages to low/manageable temps?

[Blacklash]

I plan on running 4.6 myself. I can boot and use 5.0GHz fine, however I'm not even going to try to stress test that on air cooling.

I got FX-8150 chips with 1.2625V, 1.2875V, 1.3000V, 1.3125V, 1.3250V and 1.3375V VIDs.
The best chips on air have 1.3000V+ VID, the lower ones are simply too hot to be run on air.
The 1.3375V VID chip does ~4740MHz Prime95 LargeFFT stable (4CU/8C) with 1.40V on poor UEX120 + Ultra Kaze 3krpm fan.
After that the third (0-3) compute unit starts failing and does not scale with further voltage.

The chips with higher leakage do only 4550MHz (4CU/8C LargeFFT) or so with 1.35V.
The temperature raises way too high on these and the third CU starts failing at ~70c.

When the power draw / heat is limited by disabling the compute units and leaving only one core active, the lower VID chips do ~5400MHz / 1.49V (light tests) while the low leakers do only 5200MHz or so with the same voltage.

If I would purchase a single FX cpu to be run on air or water, I would want a chip with atleast 1.3000V VID.

The things will probably change as the CPUs get more mature (in terms of manufacturing process) thou.

[FlanK3r]

thank you Stilt for your info. Im still waiting for my FX-8150, I will happy for one great under air cooling and one under LN2 .

[Dumo]

A lot of fun oc this chip, too bad theres nowhere to be found

Gotta move on

[Blacklash]

Ya' me too. I'm probably going to jump on a 2600k. I may wait on IB though.

My findings were/are very similar to stilts.

For an all around bench chip 1.30 is the sweet spot. More common than not chips with lower than 1.30 vid on ln2 crapped out at 7000-7500......

1.30 chips averaged 7600-7700 with some scaling well into the 8.2 range if they had voltage tolerance............

We found that 1.30 is the base starting vid for good air/water chips.

No it wasn't PR..........our WR chips note plural as we had a couple were both 1.30 vid........It's the range I had liked best from extensive testing and the range I bet and binned for for our Lhe runs. It costs about $1000 per chip on lhe and I bet the farm on the 1.30 vid chips...........and won.

It must be PR Watch the video closely........that will be the tell all.........

Guess I know why i distance myself further away daily from this game............

[FlanK3r]

So, I must founbd one with 1.3V and second more than 1.3 VID ...How is it with FX-8120???? The same or maybe -0.05V diference?
