cinebench 11.5

[Dr_Swizz]

Well, I did take advantage of the cold winter air.
Under normal ambient temperarures I can only run Cinebench at 5.3GHz and I cannot push the CPU/NB as high without causing the CPU cores to become unstable.
Taking all this into account, your score is indeed very respectable.

Here is a slightly better result I managed to get a few days ago:

[FlanK3r]

omg good...So, I must waiting for cold too

[Zeus]

Just what the Doctor ordered. Can you tell what batch/week for that cpu Doctor?

[FlanK3r]

I need cold, this winter is too hot in CZ ...Still over zero temperatures. Think, for 5400 MHz or so Il need about 0 C in room , now is it impossible

[Dr_Swizz]

@Zeus:

1244PGT





@FlanK3r:

It has gotten allot warmer here in Sweden too. Currently it is +2C.


When I did this, however it was -10C:

[FlanK3r]

how good is this piece with normal ambients?

[Zeus]

Dr_Swizz, thanks. Seems an awesome piece of slilcon! Haven't seen many but i think this must be one of the better clocking ones. A good 200MHz over my old 8150 which was about average. Since default clock for the FX8350 is +400MHz over the FX8150 one would expect higher clocks though.

@FlanK3r:

Well, I only have this single Vishera-based CPU do I don't have any other CPUs to compare it to directly, using the same cooling etc.

The CPU seems to be prime95 stable at 4.8GHz using 1.45V.
I have tried running Prime95 at 4.9 and 5.0GHz too and the voltage/frequency scaling does continue. I seem to be able to get the system stable and those frequencies too, but the power consumption becomes too high for my taste.

The CPU/NB is stable at 2400MHz undervolted to 1.1V.

I can run Cinebench at 5.2GHz.

I have done suicide runs by increasing the multiplier up to 5.5GHz (for all cores. My motherboard/BIOS is buggy(?) so I cannot adjust the frequency to individual cores ).

I use a small custom water cooling loop with a 50% glykol/50% water mixture for the CPU.




@Zeus:

I think you missed that I used cold winter air to cool my system when I ran the benchmark (?)

[Zeus]

Nope mate haven't missed that, the 5350MHz my old 8120 did was at temps below zero ambient temps and watercooling. Can't remember how cold it was but it was freezing and the computer was outside. At 20?C ambient temps that cpu did around 5140MHz for Cinebench 11.5.

[Zeus]

Here's the best i could do with my crappy 1236PGT CPU:



2?C ambient.. i need a new CPU!!

[FlanK3r]

this is good, no crappy with 20C ambienst around!

[I.nfraR.ed]

I's with 2C ambient and yes, cpu seems to be on the weak side. Maybe you have some really bad module?

[Zeus]

Yes in normal 20C ambient this would have been okay. With just 2C ambient i would have expected to hit at least 5400MHz or maybe even slightly more.

I don't think it has one bad module Ivan, running Prime on this CPU takes out cores randomly not just the same one all the time.

Even if it was just one it still had to go. Let's hope the next chip is (a lot) better.

[Dr_Swizz]

The temperature dropped to around -19C today so I decided to do one more try with Cinebench to see if I could get a bit closer to a score of 10.x.

@Zeus: I am going to pray that the next FX-series CPU that you get performs better.

[Zeus]

Thanks Doctor.

About your CB 11.5 score: how is any mortal supposed to top that score with water or aircooling? Absolutely out of this world! No matter how good my new CPU will be this is gonna be a hard nut to crack!

[Daveburt714]

WOW... That is definitely a nice score Doc!!!
If anyone's chip can hit 10 pts on cold air yours is probably the one...

My highest score (9.2x) was done with just a radiator outside on a budget Asus board (M5A97 R2).

Next time it gets really cold here I'll have to lug this heavy azz 800D outside and make a run at your score.
Although I have my doubts whether this chip has that much in it!

[FlanK3r]

we have still "hot", maybe my 5750 MHz chip can do this...I need only very cold for 5500+ MHz R11.5. But validation 5750 MHz 1.565V and 22C ambients is promising ,-)....

[Dr_Swizz]

Thank you guys for the kind words.

Someone who has a more powerful watercooling setup should still be able to beat my score, provided that he/she has similar chip + roughly the same outdoors temperatures. I know from previous experiences that my current setup is a little weak when benchmarking power hungry CPUs.

[Zeus]

I know for one that my water will freeze once ambient goes lower than -6?C. One would need some anti-freeze and nobody uses that stuff anymore these days.

[Dr_Swizz]

Here in Sweden antifreeze available in all gas stations and many other stores.
Perhaps you can find some online store where you can order some.

For my system I use a 50% solution. This keeps the water from freezing down to around -35C. Antifreeze does not conduct heat as well water so you probably want to use a solution with less antifreeze than this though.

[Zeus]

I think you misunderstood. It's widely available in my country, that's not the problem but i don't want it in my cooling loop. In the early days people used it to avoid corrosion now everyone is on plain distilled water with either a piece of silver or PT nuke.

We don't have temperatures lower than minus 6C herre so i dont think that will be too much of a concern.

Do you have HDD's in your rig? I've heard those can freeze, ever had that?

[FlanK3r]

There is a bit oldschool...My last newest x4 965 BE C3 with a lot of LN2 (remains of Ln2)

x4 965 BE, 1201PGT, 6.00 Points

[Dr_Swizz]

@Zeus:

Well, I do advice you to keep an eye on the temperatures & the speed of your pump. I accidentally had my water cooling setup freeze at one point when I had no antifreeze in the loop. I was doing some benchmarking outdoors and the temperature was around 0C. When it got dark the temperature dropped to about -5C. I was adjusting some BIOS settings when the system started to lock up. I noticed that the CPU temperature was around +45C. I quickly turned off the system. The water in the tubing seemed to be frozen solid. Luckily all components survived intact.

I mostly use SSDs when doing outdoors benchmarking, but when I do use HDDs I put them in a special foam container to keep them warm. Both the cold and the humidity when you bring them back indoors can kill HDDs.


@FlanK3r:

Nice, especially the 4GHz for the CPU/NB.

[Barr3l Rid3r]

really nice one flanker, it should be lethal for some FX6100


my latest run, finally mine Elpida Hyper got retired... first time I could make an 8GB kit scream louder.

[FlanK3r]

maybe tomorow Il try again R11.5 after longer time with 8350
