The paging file is just virtual memory on HD where programs can be temporarily allocated from physical RAM when program is idle (allows for quicker starts), need to free up ram for active process, or need to dump contents of ram. And for paging file to function properly, it needs to be (especially in cases of crash/memory dump) at least same size as total RAM installed, and usually 200-300mb larger to be on safe side. I never understood "tweaking" paging file size unless the goal is to cause unnecessary issues. Minimizing the page file, then trying to load up all ram with stress test....other than page thrashing???

I had issues with it and so did another poster up above. It would stop one of my workers due to system swap file which has to do with pagefile space. So, I upped mine manually because Microsoft recommends 1.5x your RAM size, but by default it puts it almost equal to RAM. Once, I upped it, no workers stopped.

I was mainly referring to people decreasing paging file, nothing wrong with increasing to 1.5x ram, though I wont since I dont see the benefit.

For Windows XP microsoft recommended 1.5x RAM for paging file, and that was default value set by XP. Windows 7 and Vista the default value, ie microsoft recommended is RAM size + 300mb. I doubt microsoft would recommend 1.5x RAM for windows 7, then have default value set all installations to RAM + 200-300mb. But then microsoft probably doesnt anticipate people running stress tests using so much ram it interferes with normal background tasks, especially using a program like Prime which is meant to be used in background, and since prime will only use free cycles since it runs at such a low priority, I could see that becoming an issue. I wonder if you could have avoided prime errors in that case by simply increasing priority of prime while running, using task manager. Though my solution would be use less memory for prime.

I'm beginning to think this is some sort of configuration problem and not a hardware issue.
When I try other custom blend configurations with memory size higher than around 10,000, it also gives me this other message: "Unable to allocate memory. One possible cause is the operating system's swap area is too small". I don't understand this, I have a page file of 1GB on my C drive.
Another problem is that even in the event I manage to get something like 12,000mb going in custom blend, my task monitor only shows a maximum of about 5.60GB being used, and close to 10GB being free. How is that possible?
In the latest LinX (0.6.4), when I select it to use all memory (14,000+ with only Chrome running), task manager shows nearly all of the 16GB being used, minus about 500MB for reserve. So I don't really understand what's going on with Prime (27.7).

I bet you are trying to use 32bit Prime95 with 64bit Windows

Man some of you guys have some low vcore. Seems no matter what cpu I get it's always voltage hungry. Only way I can stay north of WHEA warnings is 1.272 max vcore in Prime 95. Or is everyone even checking for those errors? If I ignored the event logs I could go much lower but still a bit higher than some of you.

Does anyone have a comprehensive explanation of what exactly the WHEA error 19 is? Mine always says "A corrected hardware error has occurred." "Error type: Internal parity error".
So does that mean a calculation was checked and corrected and all is good or the machine is on the edge of total fail or what? cpu gurus?

"Internal parity error" means the processor checked its own work and got different results. So the processor has to rerun the calculation from scratch to find out which result (if either) was correct. Once it's done rerunning the calculation, it reports the situation to the OS for logging. It goes without saying that these errors are a sign of instability and lower performance.

What I find most intriguing is that I can't get these errors to show up at all on my 2600k no matter how unstable I make it... with all the playing with overclocks and the 1000 or so BSODs over the past several months, I don't have a single whea 19 warning...

I see three or five WHEA 19 errors per 12 hour run. I think too much is being made of it, but if there are actual performance results then whoever is worried about them should show us (not GFlops.. lol).

I'm with you. I got a bad batch, too. I'm at about 1.25v so far for 4.5 and running Prime95 ver. 27.7 to make sure it's stable. Then, I'll try running ver 26.6 and see what it reports the voltage at.

I didn't look when I had the 2600K in the board. Interesting.

Well I tend to lean toward what Iketh says however I too wouldn't mind so more information.


Does anyone have a link to P95 26.6? I seem to have deleted it from the drive, all I could find on the site was 27.7.
Thanks!
