回复 7# ocw
XP下没问题，双通道和三通道跑的PPD差别不是很大，机器2*2G内存足矣,
家用电脑跑BIGADV本身运行占用内存一般在1-1.5G之间。
32位系统建议兄弟使用VSuite Ramdisk把不能识别的部分内存虚拟成硬盘缓存。
64位系统是最佳选择。
兄弟要是980X还是上2G*3内存，装64位系统,4.2G估计PPD在37.5--55.6K之间
Running bigadv WUs:
1) A system with 8 or more Physical Cores. (MUST READ NOTE #1 & #2)
2) Download the latest F@H SMP2 BETA Client (v6.30): <Click>
3) Install the F@H SMP2 Client by following this guide: <Click>
4) If you want to take advantage of the Bonus Points (highly recommended), make sure that your Passkey/Username is already qualified.
5) Run the F@H SMP2 Client with these flags before it downloads the WU:
-verbosity 9 -bigadv -smp
6) Windows OS 32/64 bit.
Notes:
1) Those of you running Intel Core i7-800 Series CPU or Intel Core i7-900 Series CPU will notice that in the Task Manager and Device Manager, 8/12 CPUs will be shown and may assume that your system is capable of running bigadv. This isn't the case. The fact of the matter is that these CPUs are Quad/Hexa Cores with HT (Hyper-Threading) thus you have 4/6 Physical Cores with 8/12 Threads while Standford recommends at least 8 Physical Cores. The only reason you can obtain these bigadv WUs is because of a loophole(confirm?) in the detection mechanism of the Client which reports 8/12 Cores to the Servers. HOWEVER, if you have an Intel Core i7 system that is Overclocked and STABLE (Read Troubleshooting below), you can try running the bigadv WUs and see if your system can fold within the Preferred Deadline (Read Minimum CPU Speed For Each CPU Model below).
2) The minimum amount of RAM is 0.50 GB/Core which turns out to be 4 GB. The recommended is 0.75 GB/Core which equates to 6 GB. The more-than-enough is 1 GB/Core which results in 8 GB. Note that 32-bit OS can't use RAM sizes above 4 GB. (This is the Official requirement for Linux and OSX. There isn't any Official word for Windows yet but RAM Usage for F@H Client is generally <2 GB)
3) A report has been made that a fast CPU with slow RAM can be overall slower then a slow CPU with fast RAM. This may be due to the fact that the FahCore_a3 uses more RAM to process the bigadv WU then the standard WU. (Further testing is required before it can be confirmed so please experiment with it and report your findings here.)
4) If you are already running the latest F@H SMP2 Client and have been qualified for the Bonus Points, use the -oneunit flag. After the F@H SMP2 Client exits, replace -advemthods flag (if you have it) with -bigadv flag. Do not use both as -advmethods may override -bigadv.
5) If you forget to use the -smp flag, your F@H SMP2 Client will download a Classic WU which will use only one core/thread regardless of how many you have.
6) If you forget to use the -bigadv flag but are using the -smp flag, your F@H SMP2 Client will download a normal a3 WU.
7) If you are using -smp X instead of -smp then it is recommended that you use a non-prime number for the X value as there is a known issue with scaling when using prime numbers. PG is aware of it and will hopefully provide a fix.
8) New users should first obtain the passkey so that they can take advantage of the Bonus Points. I recommend that they qualify for the Bonus Points by first folding normal a3 WUs and once you become eligible for the Bonus Points, you can try folding bigadv WUs.
9) Donors with slow internet connection should take the upload time of the WU Result (~100 MB) into consideration when estimating Bonus Points. If you fail to upload the WU Result before the Preferred Deadline, you will not get Bonus Points even if you have finished processing the WU before the Preferred Deadline. Availability of Standford Servers isn't guaranteed thus any delay will have a negative impact on your Bonus Points and Pande Group isn't responsible.

Project #---CPU Model---CPU Speed---RAM Used (F@H)---SMP X---TPF---OS---32/64---Dedicated---Username
Explanation Of The Terms:
Project #: -> The Project # available to Windows Users. So far there are Projects 2684 & 2685
Average TPF: -> The Average Time Per Frame for this Project. You can use HFM.NET to get this data.
CPU Model: -> What is the Processor's Model that you are using?
CPU Speed: -> What speed is your Processor running at?
# of CPU sockets: -> Most motherboards have 1 CPU Socket. The exceptions are server motherboards and EVGA SR-2.
# of cores/threads available: -> The number of Physical Cores followed by the number of Threads available.
# of threads used by fahCore_a3: -> How many cores/threads have you dedicated to F@H SMP2 Client?
RAM installed: -> How much RAM is installed in your system?
RAM used (F@H): -> How much RAM F@H SMP2 Client is using when folding. Memory value of FahCore_a3.exe can be found in the Task Manager under the Processes Tab.
OS: -> What version of Windows are you using and is it 32 or 64 bit?
Dedicated: -> Is you system folding 24/7 or do you use it for other purposes?
Username: -> In case you need to be contacted about your submitted data.
