Is there a limit on CPU Speed at E@H?

(moderation:
I recently upgraded my daughter's lappy. Having a 100% AMD crunch farm, I decided to play with the Celeron 2ghz I harvested from her laptop. I got an excellent buy on a Shuttle AN60R mobo and a Cooler Master HSF. With spare parts (2 512 sticks of KVR 2700, WD 80 gig HD, yadda yadda). I assembled the Celly box. With the Celeron stable and running at 2.9ghz, I loaded Boinc 4.45 and attached to Einstein. I got one WU with a completion time of 8 hours. Crunched one and uploaded. Got another single WU of 8 hours. Detached from E@H, went to the darkside (Boikeley) and received about a dozen WU's with 5 hour completion times. Pushed the Celly to 3ghz and all is stable, crunching 24/7. What's with E@H and one WU on a seriously OC'd box?

hmmm, my understanding is the the number of units fetched is determined by the value entered for "connect to network about every" under the general preferences.... what value do you have for this?
if one unit is taking about 8 hours, that's about 33% of a day...0.33......
so, to get more than one queued up, your value would have to be greater than 0.7?? could increase the value by mutliples of 0.33 to get more units.
Mines 0.08 because I intentionally only want one unit, but if you don't want to cause so much traffic, a value of 1.0 might get you two or three units??
I keep mine low, cause i'm worried about meeting the deadlines......

matt: My preferences are set to connect about every three days. If I let the cruncher accumulate that many completed WU's, I get nailed with the "quota eight" penalty. I have learned that I need to connect once a day and upload 4-5 WU's per box to stay off probation. Any Celeron, even at 3ghz should not be pushing that barrier. Me thinks there is some junk code on the server that has no clue about non stock proc's. This is not an endorsement for any Intel product. Having said that,it is fun to "make er sweat". This is a temporary build, I will be gutting this box when my A64 3400 arrives. Thanks for the advice and response.

The benchmarks are what tells BOINC how much work it's capable in a given time period. With your computers hidden, it's difficult to see if there's something odd with that machines benchmarks.

Heffed; The box is listed as a Celeron 2ghz in my computers. Einstein benchies are MFPS 1514.5 MOPS, and MIS 3008.06 MOPS. I'll defer to the Intel experts to interpret these. I believe it was running at 2.8ghz when Einstein ran the benchies. I did get a message about requesting zero when it downloaded work (1WU). This may be a disconnect in 4.45. Any Intel crunchers care to respond? I will try and post the Boinkeley benchies, but will have to wait till after work, my account code is at home.

Heffed; Current benchies for this proc @3.01ghz as calculated by Boinkeley are 1569 dp MIPS Whet, and 3349 integer MIPS Dhry. I Googled a 3ghz Celly (not Celly D, this is a truly factory crippled Northwood core), and based on your choice of benchmark, it hauls data about as fast as a 1.6-1.8ghz P4. Sandra rates its arithmatic operations as equal to a P4 3 ghz. Certainly a comment on Sandra. I need some feedback from any of you Intel drivers please. Is this a keeper?

Requesting 0 seconds of work indicates that the daemon believes that the queue is full, or the CPU is overcommitted.
