Invalid int value/precision 6144

Hello,

I'm running V5 prime95 on a Windows XP Pro x64 system (Q6700 with 8 GB of RAM). I'm running stage 1 and 2 work right now. I set my memory via the interface as 6144 MB.

My swap / page space (pre-assigned) is 16 GB (so 8 GB RAM, 16 GB page space).

The communications log shows:

Why is 6144 an invalid memory size on an 8192 MB RAM system?

Yes, I'm using the 64 bit version of Prime95. Yes, I know the memory only helps during stage 1 & 2 and that is what I'm using right now.

Bert.

P.S. From time to time Prime95 is getting a win32 error. I don't remember any specifics.

P.S.S. In Worker #4 I'm getting memory errors:

This is a known bug with the v25,7 version of Prime95 (still a BETA version.) You must limit the memory available to P-1 stage 2 (not stage1) to 1703 MB. George Woltman is currently on holidays and will come back in 2 or 3 weeks. He will be very busy with forced migration issues, then he will resume debugging v25 (I hope).

Is this memory limit also true for the 64-bit version? I'd expect different memory models / bugs between a 32-bit and 64-bit version.

Just FYI: My worker #3 stopped as being out of memory, but did say it had 4,452 MB of memory.
