What is Offset and what other terms are used for this in BIOS? There is no setting in my BIOS named "Offset".

I'm at work right now, so I can't really say for sure. I can say that while playing Skyrim with 100+ mods and on Ultra settings, I don't ever get above 35% RAM usage... I want to say that normal system idle with all my normal processes running is somewhere around 10% of RAM.

I think I get where you might be going with this - maybe I need to set the max pagefile size to be 16gb + the percent of RAM my normal system processes use? So, to give myself a little headroom, set the pagefile to 18.5gb max? (16gb of RAM + 15% to account for system processes)...

Old, but still in effect:

See: www.anandtech.com/show/2404/5

I question how much of that article is still valid today with the ivory cpus. For instance, in their article, vid and offset are described as completely internal to the cpu and not able to be modified by the user. Obviously, in our current systems, at least the offset is able to be manipulated by the user (necessary if OCing using offset). In addition, with our current systems, VID is routinely exceeded (i.e., positive offset). Thanks for the post as I do enjoy trying to add to my understanding of these sometimes difficult concepts.

And they are difficult concepts for sure. What was interesting at the time, was that intels dx48bt2 board behaved completely different than Asus with my QX9650. Sometimes it seems only the engineer that built the thing knows why he/she included the function! But to your point, with sandy/ivy: even with an offset vcore, i still run below the chip's hard-coded VID at a given multiplier... Seems stable by 24h p95 and IBT, but maybe its really not according to intel's specification? As long as it's fun...

I have a possibly stupid question, I've gone through the Bios of my UD5H (F15q) and have been wondering how to lower my idle voltage. On my ex4 I was able to get to -0.140 offset and compensate with +0.094v turbo to maintain stability under load. These settings gave me my vcore at idle ~1.004 and under load ~1.318. Any way to adjust idle voltage with the UD5H bios?

I see what your trying to do, but not sure why. However, I do recall way back somewhere in this thread someone that was interested in undervolting (sort of an anti OC). Search a little and see if any of that information helps.

So, I'm not certain if I've got the wrong version of P95 or what. Yesterday evening when I quit gaming for some family time, I started up P95 again. At 12,000mb RAM on the Custom Blend, I get several workers who won't start due to the "Error allocating memory for FFT data". When I get down to 8,000mb of RAM, everything starts up no problem. However, total memory usage for P95 only shows as just under 2gb of RAM in use. Maybe I have the wrong version of P95? I know I have 27.9, but would the 32bit version cause this type of problem with RAM usage?

I downloaded 27.7 64 bit and will replace the current version on my machine tonight...

On the bright side, P95 was up for 10+ hours with no issues when I left for work today...

you should retest with the new p95 if your older version did not have the AVX instruction set. try downloading "open hardware monitor" to get a read on the memory usage.

go here for the latest version.

http://forums.tweaktown.com/gigabyte/30530-latest-overclocking-programs-system-info-benchmarking-stability-tools.html

27.9 is the current build. Why would you be using the 32-bit version when your os is 64? Use the correct version and give it a go. I usually run the std test first to check stability of my oc. First for an hour, then 12, then if that is ok, I go to custom blend and run 90-95% (whatever is recommended on this thread on page 1) of ram for 12 then 24 hrs.

I was using the newest version - sadly I can't be positive that I downloaded the 64 bit 27.9 or 32 bit. I was going to use 27.7 because that's what the rules for the Stable / Suicide club say to use - I had figured that this was because of some questions about the 27.9 build.

So, to recap, my problems present in build 27.9, which I would assume has the AVX instruction set?

Also, on the HW monitor - Open Hardware Monitor looks just like the CPUID Hardware Monitor that I already have - are there any real differences?

Thanks!
