Nehalem,One cpu to rule them all!

This is what the BOINC benchmark looks like in the task manager on my QX9650. It runs a short burst on all 4 cores and then another short burst on core 0. I'd be curious as to what it does on an I7 with HT enabled. I had a feeling this issue of "overclaiming" would come up with I7 since the BOINC benchmark is not set up to deal with virtual cores.

Have you tested the rig with any of the single redundancy projects like FAAH Dave? IIRC points are claimed and awarded via a small benchmark run within each work unit. I would think the claim/award ratio would be much better if the bench is run with all 8 cores crunching.

Just been running the HCC project due to preference and continuity on the numbers so I'd get a decent "feel" for what the machine is doing.
The benchmarks between HT enabled and disabled are very small.. maybe 100-150 difference..
The key to see what the real power is when you disable HT and run 4 WU.
It does those in app 2 hours 25 minutes.
That's at 3733mhz.
My Q6600 at 3600 does the same WU in just under 3 hours, like 2 hours 57 minutes..
With HT enabled it does 8WU in 4 hours 20-25 minutes but I think it is working "harder" as temps between HT enabled are a solid 6C higher..

[fallwind]

Oops, I forgot to upload the screenshot...lol! It's up there now. When you run the benchmark with HT enabled, does it load up all 8 cores during the initial burst, or only the 4 real cores?

[jcool]

Well it does load up all 8 cores on a Harpertown.. if only for seconds.

[deepsilver]

Stop posting pictures!! It's so hard to resist buying one

Not my problem.

[jcool]

Lol, those Corsair mems look exactly like the 256MB DDR Platinum sticks I paid a fortune for in 2001. That's right, 3500C2 mems.. handpicked Winbond BH-5
And they still run today, now that was quality hardware.

[Martijn]

BH-5, oh yeah

Those were the chips that clocked like D9 these days but couldn't die when you gave them more volts

Has someone shot there whole wallet yet or too soon to tell? Also welcome back Dave you have been greatly missed.

You wanna talk about shooting the wallet.

*looking at my wallet*

I dont think ive been so poor since my freshman year in college. :\

Hera is seriously killing me financially.

I think i understand what you old ST people went though, and why you wanted to sell it at one point in time.

The financial commitment for one of these monster classes, is just outragous.

:\

Not my problem.

Oh yeah i can play that game too
*whisper*.. mine are still under NDA also hence why the code is grayed out.
Bet your even drooling now...

Have you looked at the buildlog for PrometheusCu? WELL over 10k on just a C2Q setup.

Get into modding, and then wonder why you're broke. Why else do we seek sponsors so often? That money tree in the backyard is misleading, I haven't gotten any money from it yet. Just these funny white seed pods.

/goes to find an AC supplier...

[NaeKuh]

koolancedean said he would sponsor my ST II rig with 2 koolance blocks.
Ima throw it on to make them happy, if they perform great, keep them, if there on par, keep them, if they have a hugh performance cut, then recycle them on my sossoman setup.

Bei Fei is commited in making me my STII board blocks.
Extra Hardware already bought. I am even tempted to throw both a HD4870X2 AND 9800GX2 on the same board and run each monitor off each card.



Other then that, dude, the hardware cost is killing me.
My chiller is still being built and i havent finished paying for that even, let alone the st2 board. if and when i can get one. :\

Dont know what kills me more, having chips and no board, or not having anything at all.. or holding a nda and not being allowed to speak of anything at all.

Been in all 3 situations and they all SUCK!

stock cooler?

[bowman]

Stock cooler and no special sauce (i.e. no AS5). Waiting for TRUE 1366 kit..

Bowman could it be the temp readout is wrong and chip is cooler than what is reported?

Might be, Nehalem implementation in Real Temp is apparently still a work in progress so who knows. As long as it's under 100C it'll be okay.

Man thats scary.. I consider 70C an absolute max on this or any other chip.
I'm at 61C at 3733mhz and thats high to me.

What application is reporting 61C on yours? Or is that BIOS temp?

Oh, okay.

Now I want my TRUE 1366 adapter more than anything..

Seriously water is the way to go with these. They run hotter than the 45nm Yorkies and need the added edge of water cooling.
I think 4000 for 24/7 work is possible with water and as soon as I can afford the parts I'm going that way.

Dave, you will have your CPU block in December...it will be my Xmas gift to you.
