Going back to Folding?

[C.C.Reed]

Which 4P motherboard does it have? Arima, Tyan, Supermicro? How is the BIOS setup? Check these settings. You can drop some TPF.

- PowerNow set to Disabled
- NUMA/SRAT set to Enabled
- Node Interleaving set to Disabled
- Bank/channel interleaving set to Auto or Enabled
- Tyan boards - Ungang DCTs set to Always

My Supermicro H8QM3-2 running quad 8431s and the Asus KGPE-D16 with dual 6174s. The Asus pulls less wattage and is a little faster. I have a 4P Tyan S4985 that I could never get stable running the 6-core chips. It's sitting over in the corner. Guess I should buy some 8389s for it.

Thanks!

I've got a SM H8QME-2+ running right now with 8389's (2.9ghz) in it. The 89's are 75watt but have 2200 HT bus, unlike some of the other quad chips. They can be had for $20 each if you haggle.

On Ebay, there are some BIOS dealers that have chips for the Socket 7 mobos. I ordered some.

I bought a Tyan S4985, but can't get it to light even with a single chip. But it was $56.

Also got a Dell quad socket, brand new, for like $75. But it requires a proprietary power supply, it's not ATX or anything else I've seen.

I have a ASUS Dual G34, with Engineering Sample 16 cores x 2.3ghz in it. Not really impressed, and it costs far more than the Junk Bin quads do.

I'm still playing with it.

The Tyan was the BIOS chip, $30 on Ebay.
Now to populate it.
If anyone needs DDR2 registered ECC RAM let me know. I have surplus.

We did over 1,000,000 point in 24hrs. Congrats all!

What speed is that RAM and how much do you have? Guess I need to find 8 sticks, some eBay heatsinks, and a PSU to get my S4985 up and going again.

Probably just grab a few of these since I have quite a few Noctua fans laying around unless you found better cheaper alternatives for yours. My 8431s don't really put out that much heat so I doubt the 8389s will.

They are DDR2-667 Registered ECC 2GB.

8 sticks? PM your mailing address if you want some.

Heat sinks are a different issue. If you can find the adapter bars (cheap plastic bar that bolts to the factory hole) you can use any AMD Phenom/Athlon fan/heatsink.

All mine are passive server heatsinks.

Avoid the Dell units. They don't bolt up. They require a special mobo.

The 8389's run cool.

Note:

These are Engineering Sample 3.0ghz 83xx quads:

He wants too much. I did buy 4 to test.

EDIT: Confirmed 8391? Quad, but appear to be SE chips, which run hotter.

Ghetto Master 5000! Errr... 4985.

Junk Ebay parts thrown on a desk, started with a screwdriver. Drives are in the desk drawer.

Fans are $4 NewEgg specials just sitting on top of the heatsinks. 52 deg C when folding.
Burning it in on SMP and I will see if it folds Big.
