...Windows will auto use any spare DRAM as a file aware read cache, regardless of whether you have PrimoCache installed or not...~all your DRAM is used (dynamically) anyway. What is NOT used as extra/spare RAM is any spare GPU VRAM... This is actually a bad thing because: it results in multiple lev...

I'm in agreement with Cichy45 here. GPU VRAM does offer greater bandwidth than system RAM, but only for GPU-specific work (graphics rendering, GPUGPU, etc). Using GPU RAM more generally (as a ramdisk or disk cache) leads to it being restricted by PCIe bandwidth, which is far less than that of system...

Additionally - there's nothing unsafe about Primocache, and using a 3rd party uninstaller with software that has a kernel-level driver may not have worked so well. With Primocache, you can always use it's own uninstaller and rest assured that your system wasn't harmed. In fairness, the issue here w...

...However would like some advice as to how to best configure it best for performance and safety...Both the SSD boot drive and the 4TB HD raid share the same cache task. This task has Defer-Write of 10 sec enabled for the 4TB HDD. If you are using L1 and L2 caching, then you should consider separat...

Yes, PrimoCache will work with just L1 cache (that's how I use it) and if you are caching programs on SSD or NVMe, L1 on its own is usually the best option. However you need to choose the amount of memory to allocate to L1 with some caution - too little and performance gains will be minimal, too muc...

...It's a modal child window that the OS controls, which I don't believe XP ever added the ability for resizing to... I don't think it's that straightforward. I use WinXP SP3 also and have attached a screenshot with 4 File Open dialogs from different applications - Primo Ramdisk, BeebEM (an emulato...

Sorry for the delay in posting - but given this seems to be a case of an existing Windows install being moved to a new system (something which would pretty much guarantee BSODs on booting with older versions), it seems most likely to be a driver issue. However, try connecting the SSD to another syst...

Greatest problem with defer-write is out of order writes. This is what causes greatest issue... Haven't out-of-order writes been a feature of NTFS since its inception, plus disk interfaces like SCSI? (with features like elevator seeking and write queuing). PrimoCache may add an extra level with Def...

Just to echo Support's response, you can expect to see higher CPU utilisation since (a) PrimoCache results in memory being accessed more often and (b) with increased speed, you have a higher rate of filesystem overheads (gathering together fragmented files, updating file metadata, checking file acce...

I'd agree with Jaga's smaller block size recommendation (512KB is pretty large and will be particularly wasteful if you are accessing lots of smaller files). 16-32KB should be more practical. Assuming you have Windows and all your program files on NVMe (and keep the HDDs for non-speed critical tasks...
