System Locks Up Under Load. BLARRRG!

[clshades]

I was given a computer similar to this to fix because it was having all kinds of issues. I owned another computer which had similar issues as you however it was a fried south bridge.

The 1st computer happend to have the new ram slots (sabretooth) which only locked (clicked in) on the top. The person that installed the computer originally didnt seat the ram fully in and fried the memory channel. Unfortunately in order to run triple channel said RAM slot HAD TO WORK for the triple chan config. Your chipset I believe is dual channel so that shouldn't be the issue. I have heard/read that the x67 chipsets have some unresolved issues and the x68 counterpart is supposed to have those fixes. Don't quote me on that as I haven't investigated those facts at all so I could be totally wrong about that.

It seems to me the ram may be incompatable. Was the ram set a complete 4 stick set or 2x 2 stick sets? Are you over clocking at all? Overclocking doesnt work as well with 4 sticks of ram? Have you tried running ONLY the hdd with the games / OS installed and none of your storage drives?

The memory is 2 identical kits of 2. Made on the same day, their serials numbers from the two kits are about 20 off of each-other. I guess I could try mixing the two kits, but that seems pretty unlikely.

I'm not overclocking, and I haven't tried unplugging my second hard drive. Are you suggesting the ram isn't getting enough power because of a storage drive?

I know what the issue is (likely).

P67/Z68 are very touchy about RAM....particularly 4 sticks of RAM or individual sticks larger than 4GB.

Go into bios. Look for a setting called vtt or vccio. Stock value is 1.05v. Many users report stability around 1.10v-1.15v, but 1.20v is generally accepted as safe for day to day according to my reading. I'd either bump it up .02v at a time and test with P95, or go straight to 1.10v and test up from there.

ALSO IMPORTANT: P67/Z68 much prefers that RAM voltage, speed and timings be set manually, not by auto. So, find out all the values for your RAM and enter them manually, voltage will be either 1.50, 1.60, or 1.65v. Speed 1333, 1600, 1866, 2133. Timings, do at least the 'big 5', for example in my case that would be 9-11-9-27-2T.

I have the same mb(well3.1 rev) and cpu
Try 2 sticks of ram in the Blue slots and get it humming along first.
see how that goes if it does.

thats a very good point keto I've read that as well. Another thing to consider is the memory will request it's settings from the bios. A 4 stick set could/would ask for more power from the memory controller than 2x 2 stick sets requiring less power. Obviously the mother boards manufacturers hands are tied if you buy ram that isn't on the qvl. They can't just bump the power up automatically because it detects more ram. I would definately try Keto's idea for a day.

you Beat me to the punch hehe

first I would check see what it says inside the event viewer. then if I am having crashes while gaming I usually think it is just the crappy programming of the game but, if it persists and everything is up to date ( chipset, drivers and windows updates) then I run the stress tests sometimes two or three of them at once to really stress my PC out to see if it crashes I go from there. your crashes could be something as simple as driver incompatibility with certain games and video card combination's. although this is allot more rare these days but it used to happen quite a bit.

I'm 99.9% certain my fix above will work, he's having all the typical symptoms. I don't know why this issue isn't as widely known or diagnosed as it should be, it's fixed up a lot of unstable systems.

[FlightlessLobster]

Well, I don't want to jynx it, but so far it seems to be running stable. I've been running P95 blend for about half an hour now.
may need some tweaking yet but I seem to be on the right track. Thank you Keto, and anyone else that tried to help.

Edit: actually it crashed just as i posted this

more settings to try yet.
