Buck's 4P F@H Build(s)

[Mindweaver]

Buck did you see the EK water blocks I put the link up for? I figured you would be all over that buddy.

Are you going to complain at the seller and see if you can do anything, or just leave it as-is?

As long as it overclocks to my satisfaction, I will leave it as is. I did pay only $239 for the chip after all.

Thanks Mind! I considered going WC, but it would add too much additional cost and complexity to my set up. Plus... Winter is coming!!!!

Yea, it would cost a lot to fully water cool those beasts.. hehehe But maybe down the road or if you win the loto! lol crosses fingers... lol

Or what passes as winter there

$239 is really a stellar deal for a 12C CPU!

Have you started OCing yet?

Was gonna flash & O/C last night, but started too late(11PM). Prob start around 6pm tonight.

That sounds like a good weekend project!

Yep, gonna get a pizza and park my butt in front of the rig for the night.

My foggly little brain is telling me that, IIRC, the ES chips have unlocked multipliers. That may be how he gets to 3GHz.

You are correct and a person would be very lucky to posses such chips.

Bad news:
O/C session has begun and I've had my first victim. Lost a P8101 @ 80% due to a corrupt file during the bios flash. Started rig back up and it failed to re-start the WU and eventually dumped it.

Good news:
I'm now sitting @ 15% o/c (2.65Ghz) with a TPF of 12:09 on P8101. This is netting me 410K PPD. I'm sure I can go higher, but I must loosen my ram timings to do so. This means going to a non-XMP profile. Rig is drawing 825W at the wall and all temps(cpu,vrm,...etc) are very good.

Darn...it's a shame that you lost a nearly-complete WU

But that's certainly a great OC!
By loosening the RAM timings, do you think that it will cost you the benefits brought about by additional MHz?

It's a possibility that higher mhz/looser timings will yield nothing more than extra heat. Several 4P owners have reverted to the previous settings due to this, as heat is the #1 culprit for lost work units/instability. There's only one way to find out, but I will let it fold like this to confirm stability before I go tinkering some more.

What's the maximum temperature that you can hit with those CPUs before heat starts to be an issue with stability? I know that my Intel CPUs will do 80C+. but I know that AMDs won't tolerate that hot.

They throttle @ 70C, but you'll be losing work above 60C. Both rigs are running between 42C and 49C, so i am good so far.

[BUCK NASTY]

Finally put the 2nd Rig in the folding cart. Now I can wheel them both over to the patio door and exhaust the heat if needed. Just gotta drag around 3 extension cords. I have all 3 rigs running on separate circuits and every circuit is 20 Amp in this house.

Only some of the ES chips are unlocked depends on the batch.

The folding cart from hell

You know, I think that i7 system on the bottom looks a bit...out of place.
I think the cart would look more even with a 3rd 4P setup on it

I found some pics of my setup from 2009. Puttin out 88K PPD back then

So 50% of the FAH rigs and nearly 10x the PPD since then

[BUCK NASTY]

Was contacted by the seller of the 2nd damaged 6176 chip(missing sm resistors) because I left negative feedback. Ended up negotiating a $50.00 credit for the chip in exchange for positive feedback(yes, even I have my price), so ended up with a fully functioning 12-core Opty-6176 chip for $190.00. Not bad for a damaged chip in a rig that's pulling 410K PPD. Good Hunting!

I found another 12 core for you $30 for it, but it beeps that it has an overheat

Picked up my 2nd P8102 WU on the OPTY-6176se rig and thought I would post some eye candy of the client pulling 650K PPD. Looks like we will have 1 Million PPD out of these rigs for 3 consecutive days in a row.

Absolutely insane!

So what's the PPD difference between this and the 6180SE rig?

And have you ordered the GTX560TIs that you were talking about?

6180se rig pulls 730K PPD on the p8102's. Still up in the air on getting 2x GTX560ti's($358)or a single GTX580($369). Been scanning the PPD charts trying to decide. Gonna order tonight so they are here by next Monday.

If you go for a pair of 560 then you more or less max out your PCIe slots but with a 580 your will still have room to expand...just a thought

Agreed. I would have more total output with 560's(assuming 8057's on both cards), but little room for expansion(do have a 3rd slot, but it's tight with little airflow). Prob go with the GTX560ti's, as they would have decent resale value if I choose to upgrade to Kepler.
