The program author did a nice job explaining in his thread. Basically, he says I'd have to do a run in the billions of digits to see solid CPU usage.

I thought Y-Cruncher was hitting 100% on 16-thread Xeon systems. If they're pulling times like they are without 100% utilization, that says something.
EDIT: Particle, you need to horde ram like a dragon hording gold. You got a fever, and the only prescription is MORE RAM!
I'd be inclined to think real core count would matter more in terms of how badly the problem surfaces. For the HT people, they'll each have two threads running per physical core, and that's going to offer a much better chance of keeping them all loaded up.
might be hitting Hyper Transport bottleneck too.Quote:

1.14GHz HT between CPU and NB, but that isn't terribly important. The CPUs negotiate their own HT3 link offering 4.8GT/s.
Nvidia's replacement for Ntune has everything but vcore control. I, like you have hit an oc wall on my motherboard (Tyan S2927-E) but mine is needing some additional vcore to bump my 2389s past 3.45ghz.
That's socket 940 :(. I find references to the lga1207 funtional datasheet everywhere (#31118 and/or #41696), but not the papers themselves...Quote:

Looks like the Istanbul processors use Fr6 which is document #45603.
Hawk, what HT ref do you get up to before crashing?

That could be an issue if anything is on the PCI bus. All I have on mine is a XFI Audio Card, but I am not getting any wierd looping sound crashes that are typical with audio card problems.
I will say that my Asus KFN32-D SLI will do more than 240htt... but no shanghai support there.
Looks like we're mostly stuck in the same boat them. I don't think vCore is going to help us. Have you tried overvolting your chipset yet? I think that may be out only bet until new boards come out this fall.
I see you're using the Kingston ECC/Reg DDR2-800 like myself. Were you the chap buying out all of Newegg's stock a while back? I had to wait weeks to get a full compliment. heh
No chipset voltage control. No voltage control of any kind.Quote:

I think the Newegg supply issue was due to Kingston changing over from dual to single rank.
I have the dual rank stuff:Quote:

The dual rank stuff went OOS for a week or so, then it deactivated entirely. A couple days later Newegg listed the modules again under a new listing and it was the single rank stuff (for $5 more, naturally). I've got a mix.
isn't the HT 3.0 for core to core even then it would start at 2400 stock at 235 you'd but to 2800. HT to Nb is also chip to chip isn't it?Quote:

Hows the system coming along? Had a chance to populate those memory slots and run a slew of benchies yet?
Anyone have any experience with ASA Computers? They're a Supermicro partner and all, but I'm curious as to why they're the first and only people to have the new H8DAi+ motherboards so far. I emailed them and they assure me the boards are in stock instead of a preorder. The price is fair.

What do you guys thing? Yay or nay on this vendor? I'm anxious to get started overclocking, using crossfire, and my IOMMU project, but I don't want to get burned for $400.
I thought I read you got the new boards with new chipset? Come on lets see some 3.2ghz :)
I've got the new board. I'm still working with the creator of SetFSB to see if he can add support for my clock generator.
Use the donate button -might speed up the work flow,lookingQuote:

That's curious. When I try to run Everest, it just BSODs my system (as it also did for my last motherboard) when it tries to measure CPU frequency. I put 3250 yen in his coffer. Maybe that'll help if he notices it was my email address. :) (That's about $35)
says on http://en.wikipedia.org/wiki/AMD_700_chipset_series
that Sp5100 is Sb700.
I don't know if that helps. :shrug: but it's worth a try.
CPU-Z lists my SP5100 as an SB750, actually. It's kind of funny. :) Unfortunately no, though, I need support for my specific clock generator. It's a different one than those used on virtually all 700-series boards.
If I limit Windows to 4 CPUs, AOD will load. I just don't have control over HT ref. Of course, it would be of limited usefulness to only be able to run with 4 CPUs, but it would have been a start. Apparently AOD crashes if it doesn't have enough display spaces for the number of CPU cores or GPU cores in a system.
