Re: write cache not working with RamDisk Pro

My kernel is patched so my OS sees the entire 12GB of memory and uses it. I've read the thread discussing the patching, and things aren't likely to be so simple. While it is possible to increase the total amount of memory usable (up to the PAE limit of 64GB) by such patching, limits still exist on ...

Re: Failed to format this volume to the level-2 storage!

Pending an official response, does the SSD format normally and does partitioning it (and using PrimoCache to format one partition only) make any difference?

Re: write cache not working with RamDisk Pro

If you're running a 32-bit OS, then there will be restrictions on smaller blocksizes depending on your cache settings (I need 16KB+ blocksize with a 7GB cache). That's because the reported "overhead" (which I presume is the indexing for the cache) uses conventional memory, so cannot exceed...

Re: write cache not working with RamDisk Pro

Use the "custom" setting as suggested twice previously, and you should be able to set up the cache as you please. The other options (read and write) both restrict certain choices. The performance figures I posted in the Benchmarking PrimoCache thread were obtained with LFU-R. Write defer s...

Re: cache vs ramdisk

Simplest answer - a Ramdisk only contains data you put on it, so can only improve performance if you take the time to (a) identify files/folders used frequently and (b) copy them across to the ramdisk and make any configuration changes needed to ensure the ramdisk version is used (e.g. using links o...

Re: Preload currently accessed files -> improve Audio/Video/

Setting a large block size (the maximum 512KB) may help out, if you've not already tried it.

Re: write cache not working with RamDisk Pro

Re-reading your initial post, you mention using Primo Ramdisk to hold the L2 cache for Primo Cache - don't do this, just forget about L2 caching and have a large L1 cache. The suggested 50/50 split would seem a good place to start, but (if using a 64-bit version of Windows) you should calculate your...

Re: Severe memory errors with large write cache

Does changing block size have any effect (and are you using the default 4KB size)?

Re: A longer stream of urgent writes should pause the cache

Sounds like a good idea, assuming that pausing the cache in mid-copy can be done without risk of data loss. But a normal copy shouldn't exercise the CPU at all (disk write speeds limit what can be done and disk controllers should be doing most of that) unless you're using encryption. Care to mention...

Re: Configure PrimoCache with Primo Ramdisk

I'm running both and, aside from deciding how to split memory between them, there's not really any complications involved in running them together (I would suggest a 50/50 memory split, unless you have specific reason to allocate more to one product). If you have not already done so, uninstall Fancy...
