try picasa (from google) the software is definitely fast in organizing photos in your computer and easily upload it with desired resolution (including original size). The best photo organizer/uploader in one!

In terms of memory concern, don't aim to get it to 1600 or above when you're overclocking 4Ghz and up. Many users at that speed usually set their mem speed at x6 or x8 way below the indicated speed.

Recently I tried to manually configure my memory settings with the lowest possible speed(x6), 1.5DRAM voltage, QPI/VTT @1.1v, timings at 9-9-9-25-34-1T and my load temps were 6c lower! QPI/VTT does contribute in raising vcore temps.

With regards to your video glitch, are you overclocking your gpu? Have you tried ATI Tool and running it for 15-30 mins? It has nothing to do with cpu/memory. Make sure you also have the latest gpu drivers.
is it good to try to get the qpi/vtt and/or the dram voltage as low as possible without crashing? would that help in lowering the vcore voltage?
i lowered my memory ratio so now it's running at 1200. should i bother with memory timings?

i just lowered my qpi to 1.14, dram to 1.5, and lowered my memory ratio to 2:6. i was able to get a stable intelburntest at 1.3 vcore and the max temp was 84. since i'm using windows xp 32 bit, i can onyl test like 2gb of memory out of my 4gb of memory. does this affect how well IBT shows how stable my computer is?

You must make sure that you disable the XMP profile. And manually configure your highest timings possible, i based my 9-9-9-25-34-1T on my JEDEC#3 (from CPU-Z Memory specs) Just keep your DRAM at 1.5v since you are not overclocking it. This is the most stable the memory can get.

Since you are operating at the slowest possible memory frequency and timings, you don't need to raise your QPI/VTT. You now have isolated the CPU and just work on the vcore first.

Lowering qpi/vtt or dram voltage does not help lower the vcore voltage but it does reduce your core temps.

okay thanks!

i tried IBT again and it was unstable at 1.3 vcore

so i tried your 21x190 method. same voltages for everything, but i changed my memory ratio to 2:8 so it's at 1520 now. 1140 seemed a little too low, what do you prefer? it passed through edit:16 ibt tests so far and max temp was 84. is this way looking pretty good?

Ok, have about 35 gigabyte of downloads running right now so I'll try it tommorow, will give me a chance to take some bios screen pics.

It is easier if you isolate the cpu from the memory. So you would want to set the memory to slowest speed and higher timings. You can change them to higher frequency after you have found your desired cpu speed/voltage.

Also as i'm not great or an expert at this yet. Could someone please explain VTT/QPI voltages. When should you raise them, how high is too high. stuff like that.

And with RAM voltage. if you have low voltage ram like 1.35 how high can you up the voltage without it being dangerous. and what is the average overclock of ram. how many mhz?

QPI/VTT explained

My mem sticks have XMP rated at 1.35v 1600Mhz. But I already tried up to 1.65v and still safe. Don't go beyond that. But 1.65v is really unncessary since overclocking the memory is the most complicated thing out there especially if you tinker with the timings and speed. Now I don't use the 1600Mhz. I go below since I use x8. My voltage is at 1.5-1.56v. If you really plan to overclock with your 1600, it seems you can up to 1800. Beyond that is not worth it. Better buy a 2000 at stock instead.

Thought I'd also point out here that keeping the VTT and DRAM Voltage within .5v of each other is highly recomended. This doesn't get discussed all that much probably because it is a pretty big spread and keeping them within .5v is almost automatic. From alot of the overclocks I've seen on the 760's I could see it becoming a problem though as they can run very low VTT with moderate overclocks. Keep in mind also that it isn't all that uncommon for P55 boards to overvolt the DRAM Voltage from what is set in BIOS so staying within .4v might be even safer. This is not so much of a stability problem as it is a fry your CPU a few months down the road sort of problem.

Also on my system anyway and I believe it to be true of other P55/i5 systems the baseclock can be very VTT dependent especially over 200.

What is the max vcore you can feed this thing? With High vdroop 1.387v (bios) is 1.304 load and it isn't enough for my OC. But with Low Vdroop 1.35v (Bios) is 1.392 (load) it is stable but seems high.

191x21
VTT 1.206
DRAM 1.65 7-9-7-24
PLL (auto) 1.8

thanks.
