I was wondering why my laptop was running noticably slower after installing this app when I remembered that Yonah doesn't do SSE2. Can anyone give me an xml file to switch inprogress tasks back from 6.05 to 6.04?

I could be wrong, but I believe not only does Yonah have SSE2 but SSE3 instructions as well.

Correct. Yonah is the first generation Core Duos (if I remember correctly) and does support SSE2, SSE3, and SSSE3. I can confirm this firsthand as my Mac uses a Yonah core at 2.0GHz.
EDIT: Actually, all Intel Core processors (only Core, NOT Core 2) are Yonah cores.
huh. If that's not the problem, I'm baffled at its performance. With 604 it was averaging ~20hrs/WU, the same as my desktop. Now the dekstop's runnign ~12hrs, while it's at 30. Other apps aren't taking more than a few percent of the CPUs time, and every time I've checked over the last few days it's been running at full speed so it's not thermal throttling...

Here's some info I was reading through

The shortcomings of Intel Core (Yonah) are:
integer performance decreased slightly due to higher latency cache
The same or even slightly worse performance per watt in single threaded or non-parallel applications compared to its predecessor.
32-bit processes only. 64-bit processes are not supported.
High memory latency due to the lack of on-die memory controller (further aggravated by system-chipset's use of DDR-II RAM)
Limited Floating Point Unit (multiply/divide) throughput for non-parallel computations or single-threaded processes; this is due to the smaller number of floating-point units in each CPU core compared to some previous designs.
The Yonah platform requires all main-memory transactions to pass through the Northbridge of the chipset, increasing latency

That must be comparing it to AMD processors. AMD's had on-die memory controllers for a while (it's called HyperTransport), but Intel's just started doing it with their Nehalem processors being released on the 17th (this Monday). So those memory latency problems can be attributed to basically any Intel processor, since they've been using the front side bus to the Northbridge for quite a while now.
And yes, Core Duo/Yonah was one of the last 32-bit only processors. As most people have figured out, the Core 2 series are all 64-bit, and Intel stopped making the Pentium brand in 2006. One thing I hadn't quite noticed when buying the Mac... Now I'm stuck with 32-bit on the Mac, which has proved to be quite an annoyance at times.

Could be just an update of BOINC from 5.8.15 might help.

They stopped making pentium-4/pentium-m chips, but the branding lives on for lowend CPUs. "pentium dual core" laptops use a yonah CPU with a very small cache. The desktop e2xxx and e5xxx(?) chips are core2d's with very small caches and also branded as "pentium dual core".
Could the people that reported problems with renaming the checkpoints in this 6.05 App please test 6.07 Beta and report there if this App fixed their problem (if not running Win98/ME of course)?
