FEATURED Summer CPU BBQ

[Mr.Scott]

For those using windows xp for 2D bench, do you use the 32 bit or 64 bit. Have you noticed a difference is the benches?

Depends on the bench, but generally 32 bit XP for 2D.

Thanks, very helpful
Just noticed that xp shaves a few seconds off on super pi compared to windows 7.

 

[dejo]

for superpi without tweaks I think server 2003 is better. but xp is faster when tweaked out

 

[ATMINSIDE]

ATMINSIDE / Intel / 4C8T / PiFast / 16.21s


ATMINSIDE / Intel / 4C8T / wPrime 1024M / 180.274s x4 = 721.096s


UPDATED ATMINSIDE Total = 2864.131

 

[marc0053]

Update on super pi 32m

marc0053 - intel i7 5960x / 8 cores - HT disabled / SPi 32M / 7min : 31.375 sec

 

[ATMINSIDE]

Nice run marc!
What can you get to when you crank it up??

 

[marc0053]

I can get the cpu up to 4.9GHz with HT under ambient water with 1.48V vcore and 2.1V input volts.
I went through about 10x retail 5960x to get this nugget...

Never tried pushing the 5960x in 2D benches except cinebench R15.

Once I get the tweaks and efficiency in place at 4.0GHz I'll give it a go a full speed on water.
Just received a phase changer yesterday locally and never played with one before so I'm looking forward to it.

 

[ATMINSIDE]

Definitely get all you can on water before using the phase, don't want you killing a nice chip before you get all the benches submitted!
Have you tried seeing what it'll do at 2 cores no HT for PiFast/SuperPi?

 

[marc0053]

Not yet but hopefully tonight.

Question: Can we have uncore frequencies higher than 4.010 GHz?

 

[ATMINSIDE]

Yes, uncore can be as high as you can manage. The only limit is CPU speed.
That said, I'm submitting at the 4GHz speed because Z97 won't let you exceed CPU speed w/ the CPU Cache speed.

 

[dejo]

with haswell we have some limitations for sure

 

[Dr. McCoy]

Ugh!
Got slaughtered in GPU PI, I'll have to redo my run with it and see what I can do.
I'll admit I wasn't using my best GPU but all of what I have are older ones so don't expect anything great here vs what some of you are using.

You should be running on the CPU, not the GPU.

 

[marc0053]

Do you need an amd gpu to run gpu pi or can use an nvidia card with the amd addon posted a few days ago?

 

[ATMINSIDE]

The OpenCL 2.0 installer? You have to be running certain AMD GPU's to utilize that.
You can utilize OpenCL 1.2 with any recent GPU though.

 

[Dr. McCoy]

You should be running on the CPU, not the GPU.

I'll doublecheck and see what goes - Probrably ran it the wrong way.

 

[ATMINSIDE]

If you're not sure, post a screenshot of all your settings in the bench and we can straighten you out

 

[dejo]

you can install an amd driver when an amd card is resident and it will work even after you take the amd gpu out

 

[Blaylock]

...Z97 won't let you exceed CPU speed w/ the CPU Cache speed.

Hmmm. My Pifast run from the other day my CPU was 4.0 with the cache at 4.7 IIRC.

Huh... Mine won't do it.
