Even as the double checker, I'm honored to catch a Mega.

Thanks for the info Scott about HT & minimum memory. I initially purchased just 4 GB for my system. I ran Windows task manager & discovered that my free memory was only 166MB. So, I just ordered another 4GB DDR3 memory from NewEgg. With 4 GB < $100 there is no reason for memory to be a bottleneck.

Just picked up a Intel i7 875k & Windows 7 - 64 bit. Was wondering if hyper-threading feature was beneficial or not with Primegrid? I read that some applications can receive a boost or sometimes a penalty running with hyper-threading. Was going to test both ways but felt it would be easier to ask what most i7 owners experienced first. Thanks...

4) Message boards : Number crunching : Getting a prime number!!! If ever!! (Message 16684)

I went through 8500 WU with 0 Proth primes, then discovered 3 in one day. The key is persistence. My ratio is currently 1 proth every 3500 WU, but it varies. It seems to be either feast or famine, so again persistence is key...

Looks like I accidentally turned auto-reporting on. After getting a heads up I did receive the prime.

Last week under my account, the Proth Prime found number increased to 6, but my prime number list remained at 5. Occasionally this happens & after a day or two the new prime shows up. But it has been a almost a week & I have searched the pending tasks & nothing seems that old. Was wondering if the prime was in error or what could be causing the delay.

Thought I found my fourth unique prime, but searching the Top 5000 database showed 29*2^627167+1 was entered back in June 2005. Well, at least it counts at PrimeGrid.

I wnet through 8,000 WU with no primes, then I hit three in one day. Now over 12,000 WU, so another dry patch of 4,000. But the ratio of 1/4,000 PPS prime to PPS WU is almost dead on to my current ratio. Persistance will pay off.

Thanks... Looks like they just showed up under my account. So just a few hour wait.

I've been crunching primes on PrimeGrid for 7 months & not one prime. Thought my PC was cursed. To my surprise, the last day of the Tour de Primes, I receive not one or two, but three primes within a couple of hours. What are the odds!

1085*2^556987+1
1151*2^558549+1
385*2^557488+1

I've just finished reporting them into the Top 5000 Largest Known Primes database. How long does it normally take before the primes are added to primegrid? When I look at my prime list, I still have the following -
